Regulation of Real Estate in Coastal and Tourist Areas

Along Mexico’s 11,122 kilometers of coastline, few strips of land concentrate more legal complexity—or generate more active litigation—than the federal maritime-terrestrial zone. For investors, developers, and resort operators in Quintana Roo’s tourist corridor, the regulatory architecture governing this federal zone determines what can be built, under what legal title, and with what degree of security. The consequences of misunderstanding this regime are direct and well-documented: concession revocations, demolition orders, PROFEPA enforcement proceedings, and—where significant ecological damage is involved—criminal exposure under Articles 420 and 420 Bis of the Federal Criminal Code. That criminal dimension is addressed in full in the enforcement risk section below; it is not a rhetorical caveat but one of the most serious risk categories facing coastal developers and operators who deviate from authorized use conditions.

Constitutional and Statutory Architecture of Mexico’s Coastal Public Domain

The legal foundation is Article 27 of the Political Constitution of the United Mexican States, which vests original ownership of all national territory in the Nation and establishes federal dominion over the maritime-terrestrial zone, internal waters, and adjacent seas. This constitutional provision precludes any private party from acquiring ownership of the ZOFEMAT through purchase, adverse possession, or any civil law instrument—a limitation that courts have consistently enforced regardless of the age or apparent regularity of the conflicting title.

The operative statute is the General Law of National Assets (LGBN), published in the Official Gazette of the Federation on May 20, 2004, which replaced its 1982 predecessor and substantially modernized the management framework for federal public domain assets. Article 7 of the LGBN catalogues maritime beaches, the ZOFEMAT, and lands reclaimed from the sea among the assets comprising the federal public domain. Article 9 establishes their inalienability, imprescriptibility, and non-attachment—characteristics that flow directly from the constitutional public ownership regime and cannot be derogated by administrative act, contract, or local law. This is not a procedural technicality: it is the structural premise that determines the legal nature of every transaction involving coastal land in Mexico.

ZOFEMAT: Legal Nature, Delimitation, and Federal Administration

Chapter IV of Title V of the LGBN (Articles 119 through 128) defines the three principal components of Mexico’s coastal public domain. Maritime beaches (maritime beaches) are the areas covered and uncovered by ordinary tidal action. The ZOFEMAT is the twenty-meter strip of dry, passable land immediately contiguous to those beaches, measured inland from the highest ordinary tide mark (ordinary high water line). Where the coastline consists of rocky terrain, cliffs, or bluffs rather than sandy shore, the ZOFEMAT is measured from the upper edge of the cliff. Lands reclaimed from the sea (lands reclaimed from the sea)—a category of particular relevance to Cancún’s Zona Hotelera, which was substantially constructed on reclaimed ground—are subject to the same public domain regime and may only be occupied under federal concession or authorization.

Administrative authority over the ZOFEMAT is vested in the Secretariat of Environment and Natural Resources (SEMARNAT), acting through its General Directorate of Federal Maritime-Terrestrial Zone and Coastal Environments (DGZFMTAC). The implementing instrument is the Regulation for the Use and Exploitation of Territorial Sea, Navigable Waterways, Beaches, Federal Maritime-Terrestrial Zone and Lands Reclaimed from the Sea (DOF, August 21, 1991)—a text now more than three decades old, widely criticized by practitioners and legal scholars for failing to reflect contemporary coastal management standards or adequately address climate-driven geomorphological dynamics.

ZOFEMAT delimitation is not a cadastral formality. The determination of the línea de pleamar máxima ordinaria constitutes a sovereign act of federal authority—not reviewable on the basis of pre-existing private title records, municipal cadastral registrations, or notarial instruments predating the LGBN’s entry into force. This proposition reflects a doctrinal tendency embedded in multiple circuit-level resolutions from the Tribunales Colegiados de Circuito in administrative matters, including criteria developed in amparo proceedings before circuits with jurisdiction over Quintana Roo, where the intersection of SEMARNAT delimitation surveys and private cadastral claims has generated a recurrent line of litigation. Specific tesis registered in the Semanario Judicial de la Federación addressing delimitation challenges in the coastal zone have consolidated around the principle that SEMARNAT’s technical determination is an acto de autoridad subject to review exclusively through administrative and amparo channels, not through civil property actions. Practitioners requiring pinpoint tesis numbers should query the Semanario Judicial de la Federación digital platform using search terms zona federal marítimo terrestre, pleamar, delimitación, SEMARNAT for current registered criteria, as the electronic registry constitutes the authoritative verification source. This delimitation doctrine has direct consequences in Quintana Roo, where coastal erosion and storm-driven geomorphological change continuously shift the physical reference point, generating recurrent disputes between federal delimitation surveys and private boundary records. Investors who acquire coastal assets without commissioning an independent georeferenced ZOFEMAT survey assume a risk that title insurance alone cannot adequately cover.

A particularly acute dimension of the delimitation problem is whether SEMARNAT treats the línea de pleamar máxima ordinaria as a fixed historical datum established at the time of the original concession grant, or as a dynamic measurement updated at each concession renewal cycle. The legal and practical consequences of this distinction are substantial. If the baseline is fixed, structures built to an earlier shoreline reference may remain within authorized coordinates even as the physical coastline recedes landward. If the baseline is dynamic—recalibrated to reflect current geomorphological conditions at each renewal—the scope of the federal zone expands with erosion, potentially enveloping structures that were lawfully outside the ZOFEMAT when originally constructed. Current SEMARNAT field practice in Quintana Roo does not resolve this question uniformly: the DGZFMTAC has in some renewal proceedings applied updated topographic surveys reflecting post-storm shoreline retreat, while in others it has honored the original concession coordinates. No published SEMARNAT technical criterion or binding administrative resolution establishes a general rule for Quintana Roo coastal concessions as of the date of this article. The absence of such a rule represents a structural gap in the regime: there are no pending legislative proposals at the federal level that specifically address dynamic versus fixed pleamar baseline methodology, though SEMARNAT’s broader coastal management agenda—reflected in its Estrategia Nacional de Manejo Costero Integrado—acknowledges the geomorphological change problem without prescribing a delimitation resolution mechanism. For investors and developers, this uncertainty has direct transactional implications: a concession boundary that appeared unambiguous at acquisition may be contested at the first renewal, and structures positioned near the twenty-meter boundary carry the highest exposure to baseline recalibration disputes.

The Concession Regime: Access, Terms, and Operative Risks

No private party may occupy, use, or exploit ZOFEMAT land without a federal concession granted by SEMARNAT. The Reglamento de ZOFEMAT (1991) establishes an administrative process requiring: a georeferenced technical survey of the requested area; a project description specifying the intended use; proof of the applicant’s legal capacity; and a favorable opinion from the relevant municipal authority. Concessions are granted for initial terms of five to fifteen years, renewable subject to fee compliance and adherence to the authorized use conditions.

Annual concession fees are governed by Articles 232-B et seq. of the Ley Federal de Derechos, which establish per-square-meter rates calibrated by location category and type of exploitation. These provisions govern ZOFEMAT fee schedules in the versions of the LFD applicable to recent fiscal years; practitioners must verify the current operative article numbers against the version of the LFD in force for the relevant fiscal year, since fee tables and their structural location within the statute are subject to annual legislative revision through the federal budget process as implemented by the Ley de Ingresos de la Federación. In Quintana Roo’s tourism-classified coastal frontage—the highest-rate category in the national fee schedule—fee compliance constitutes a significant and recurring operational cost. Persistent non-payment is among the most common grounds for revocation and among the most frequent deficiencies identified in distressed asset due diligence.

A ZOFEMAT concession does not confer ownership; it confers a precarious administrative right to use federal property for specified purposes. The legal nature of ZOFEMAT concessions as precarious administrative authorizations—not property rights—and the principle that revocation does not constitute expropriation for constitutional indemnification purposes under Article 27, reflects a doctrinal tendency consistently expressed in circuit-level resolutions and doctrinal commentary aligned with Primera Sala criteria on administrative acts and constitutional rights. This proposition has been developed extensively in amparo proceedings before Tribunales Colegiados with jurisdiction in federal administrative matters; practitioners should consult the Semanario Judicial de la Federación electronic platform under the search terms concession, federal maritime-terrestrial zone, revocation, expropriation, indemnification for registered tesis directly on point, as the specific tesis numbers require verification against the current electronic registry to ensure citation of the operative registered criterion. This distinction is systematically misunderstood by foreign investors who conflate the economic value of beachfront concession rights with the legal stability of ownership. The Reglamento further provides that permanent structures built on ZOFEMAT land revert to the Nation upon concession expiration, without compensation. Enforcement of this reversion clause is procedurally complex and frequently litigated, but it constitutes a real and underappreciated liability in restructuring and distressed-asset scenarios.

Concessions may be transferred to third parties only with SEMARNAT’s prior written authorization, and such transfer does not extend the original term. The specific transfer authorization requirement and its legal consequences are governed by Articles 57 through 60 of the Regulation for the Use and Exploitation of Territorial Sea, Navigable Waterways, Beaches, Federal Maritime-Terrestrial Zone and Lands Gained from the Sea (DOF, August 21, 1991). Article 57 establishes the prohibition on transfer without prior written SEMARNAT authorization; Articles 58 through 60 set out the procedural requirements for the authorization application and the consequences of non-compliance, including that an unauthorized transfer is unenforceable against the federal authority and constitutes an independent ground for revocation of the underlying concession. In corporate acquisitions involving hotel or resort assets that operate on ZOFEMAT frontage, this requirement means that deal structuring must address SEMARNAT approval as a condition precedent—not a post-closing formality.

The practical timeline problem created by the transfer authorization requirement is acute and routinely underestimated in M&A transactions involving Quintana Roo coastal tourism assets. SEMARNAT transfer approvals in tourism-classified zones in Quintana Roo routinely require between six and eighteen months from the date of a complete application, depending on the complexity of the concession area, the nature of authorized uses, and the administrative workload of the DGZFMTAC. Deal structures that do not account for this gap expose buyers to the risk of taking title to a hotel or resort while the underlying ZOFEMAT concession remains in the seller’s name—a condition that, if prolonged, can itself generate an enforcement vulnerability. Practitioners active in this sector have developed several structuring tools to manage this timeline gap. First, interim operating agreements between seller and buyer can be structured to give the buyer de facto operational control of the asset—including collection of revenues, management decisions, and environmental compliance obligations—while the concession transfer authorization remains pending; these agreements must be carefully drafted to avoid themselves constituting an unauthorized transfer under Article 57. Second, SEMARNAT no-objection letters or formal acknowledgment of a pending transfer application can be established as a condition precedent to closing or to release of a portion of the purchase price, converting the timeline risk from a structural ambiguity into a contractually managed milestone. Third, purchase price holdback mechanisms—typically structured as escrow arrangements representing between five and fifteen percent of the total consideration—can be calibrated to the estimated cost exposure of a revocation scenario, with release conditional on confirmed SEMARNAT transfer authorization. The specific design of these instruments requires analysis of the individual concession terms, the asset’s regulatory standing, and the risk tolerance of the parties; no standard structure is universally applicable across Quintana Roo coastal transactions.

Criminal Enforcement Exposure: Articles 420 and 420 Bis of the Federal Criminal Code

The criminal dimension of ZOFEMAT violations is the most serious enforcement risk in this regulatory framework and deserves analytical treatment beyond introductory reference. The applicable provisions are Articles 420 and 420 Bis of the Federal Criminal Code, which establish the federal criminal types for environmental crimes against ecosystems and natural resources, as complemented by the environmental protection framework of the LGEEPA.

Article 420 of the Código Penal Federal imposes imprisonment of one to nine years and fines of three hundred to three thousand días multa on any person who, without authorization or in violation of applicable legal provisions, carries out works or activities that damage the natural habitat of wild species, destroys or severely alters ecosystems or their elements, introduces invasive species or pathogens that damage native ecosystems, or causes the death or destruction of specimens of species considered threatened or endangered. In the coastal context, this provision is directly engaged by unauthorized occupation of ZOFEMAT land that results in destruction of natural habitat—including the clearing of coastal vegetation, dune stabilizing flora, or adjacent wetland margins—as well as by construction activities that alter tidal dynamics or eliminate intertidal habitat without MIA authorization.

Article 420 Bis of the Código Penal Federal establishes an aggravated criminal type applicable specifically to acts that damage, destroy, drain, fill, or otherwise adversely modify mangrove wetland systems, coastal lagoons, coastal dunes, and wetlands in general. The penalty range under Article 420 Bis is two to ten years’ imprisonment and fines of six hundred to six thousand días multa. This provision is of acute operational relevance along the lagoon-facing coastlines of Solidaridad, Tulum, Puerto Morelos, and the Costa Maya corridor, where mangrove ecosystems are dense, their ecological connectivity with the ZOFEMAT is direct, and PROFEPA’s enforcement posture has intensified following a series of high-profile investigations into unauthorized mangrove removal associated with tourist infrastructure projects. The elements of the Article 420 Bis type require proof of the harmful act, the resulting damage to the protected ecosystem type, the absence of lawful authorization or the deviation from the terms of any authorization granted, and the defendant’s knowledge of the prohibited nature of the conduct. Corporate officers, project managers, and environmental compliance signatories have all been subject to criminal investigation under this provision in Quintana Roo enforcement proceedings; criminal exposure does not attach exclusively to beneficial owners.

The interaction between PROFEPA administrative enforcement and federal criminal prosecution is sequential in some proceedings and parallel in others: PROFEPA inspections that identify evidence of criminal-level ecological damage are required to refer findings to the Fiscalía General de la República for criminal investigation. Developers and operators facing PROFEPA inspection proceedings in ecologically sensitive ZOFEMAT areas should treat the criminal referral risk as a live possibility from the moment an inspection is initiated, not only after formal proceedings are opened.

Coastal Development in Quintana Roo: Overlapping Regulatory Layers

Development along the Quintana Roo coast is subject to a regulatory matrix of exceptional density. Beyond the federal ZOFEMAT regime, developers and investors must navigate:

• Articles 28 and 29 of the General Law on Ecological Balance and Environmental Protection (LGEEPA, DOF January 28, 1988, as amended), which require an Environmental Impact Statement in Regional or Particular Modality for any work within the federal zone or that may affect its ecological integrity. The operative procedural instrument governing Environmental Impact Statement requirements—including the distinction between Regional Modality and Particular Modality, the content requirements for coastal zone studies, the timeline for SEMARNAT review, and the specific triggers for each modality—is the Regulation of the General Law on Ecological Balance and Environmental Protection regarding Environmental Impact Assessment (DOF, May 30, 2000, and subsequent amendments). Articles 5 and 6 of that Regulation establish the activity categories requiring Environmental Impact Statement in Regional Modality versus Particular, with coastal zone works, tourist infrastructure, and works affecting federal coastal land specifically enumerated. Articles 9 through 17 govern the content requirements, submission procedures, and maximum review timelines for each modality. For practitioners structuring coastal projects in Quintana Roo, the Regulation—not the parent statute articles alone—is the operationally determinative instrument. SEMARNAT’s procedural guidance documents updated in 2022 through the DGIRA (General Directorate of Environmental Impact and Risk) provide additional guidance on documentation standards and the application of coastal modality determinations, and should be consulted alongside the Regulation for current administrative practice;
• NOM-022-SEMARNAT-2003 (DOF May 10, 2004), which prohibits draining, filling, or otherwise modifying mangrove wetland systems—a restriction of acute operational relevance along the lagoon-facing coastlines of Solidaridad, Tulum, and Puerto Morelos, where mangrove coverage is dense and PROFEPA enforcement is active;
• the Territorial Ecological Planning Program (POET) of the State of Quintana Roo and the municipality-specific Local Ecological Planning Programs (POEL), which assign legally binding land use designations, maximum surface coverage coefficients, height restrictions, and mitigation requirements through Environmental Management Units;
• the Law on Human Settlements, Territorial Planning and Urban Development of the State of Quintana Roo and individual municipal Urban Development Plans, which impose coastal setbacks and density limitations beyond the 20-meter ZOFEMAT baseline; and
• FONATUR’s planning authority in designated tourism development zones—Cancún, the Riviera Maya corridor, and associated infrastructure areas—which adds a fourth layer of concession and authorization requirements with its own administrative procedures and timelines.

The practical result of this multiplicity is a regulatory environment in which a project may hold a valid ZOFEMAT concession, a favorable Environmental Impact Statement resolution, and a municipal construction license—while simultaneously facing a PROFEPA inspection proceeding initiated on independent grounds, or an administrative challenge from an adjacent ejido asserting overlapping territorial rights. The interaction between ejidal land tenure and the ZOFEMAT regime, particularly in the Tulum and Costa Maya corridors where ejidal boundaries frequently abut federal coastal land, represents one of the most litigated and legally complex fact patterns in current Quintana Roo real estate practice. The absence of a unified federal coastal zone management statute—capable of coordinating these competing authorities under a single planning framework—is a structural deficiency that increases transaction costs and fuels litigation across the entire sector.

Comparative Perspective: Spain and Brazil

A comparative analysis reveals both the relative weaknesses of Mexico’s coastal regulatory architecture and the reform directions available to legislators.

Spain. The Law 22/1988, of July 28, on Coastal Zones, substantially reformed by Law 2/2013, of May 29, on Protection and Sustainable Use of the Littoral, provides an integrated statutory framework governing the entire maritime-terrestrial public domain. Articles 3 and 4 of the Coastal Law define the public domain expansively to include the intertidal zone, adjacent beaches, stabilized coastal dunes, cliffs, and coastal wetlands. The statute then establishes a cascading system of protection instruments: a six-meter transit easement (transit servitude) immediately landward of the public domain boundary; a 100-meter coastal protection easement (protection servitude) within which construction is severely restricted and subject to exceptional authorization; and a 500-meter influence zone within which territorial planning instruments must take coastal impacts specifically into account. The 2013 reform extended maximum concession terms from 30 to 75 years—significantly improving investment security for coastal tourism operators operating under the public domain regime. Mexico has no equivalent of the protection easement or the influence zone: beyond the 20-meter ZOFEMAT, adjacent private land is subject only to local planning law, with no mandatory federal constraint deriving from coastal proximity.

Brazil. Brazil’s coastal regime is grounded in Decree-Law No. 9.760, of September 5, 1946 and in Article 20, VII of the Federal Constitution of 1988, which vest federal ownership over terrenos de marinha—a strip of 33 meters measured inland from the mean high tide line of 1831—and over coastal accretion lands. Administration falls to the Secretariat of Union Patrimony (SPU). Brazil employs aforamento (a form of emphyteusis) and cessão de uso as primary instruments for regularizing occupation, offering occupants greater long-term legal predictability than Mexico’s concession model while imposing significant annual foro obligations and laudêmio charges on transfers. Brazil’s environmental overlay—the Forest Code (Law No. 12.651/2012) and the Atlantic Forest Law (Law No. 11.428/2006)—creates a parallel statutory protection regime for coastal vegetation, including restingas (coastal sandy vegetation formations), that has no direct federal equivalent in Mexico beyond the mangrove-specific provisions of LGEEPA and NOM-022.

The comparative lesson is consistent: Mexico’s 20-meter ZOFEMAT provides a substantially narrower coastal protection band than any major comparator jurisdiction; the operational concession model offers weaker long-term security than Brazil’s emphyteutic alternatives; and the absence of a unified coastal management statute generates the jurisdictional fragmentation that increases costs and uncertainty for all market participants.

Doctrinal Framework and Legislative Gap Analysis

The scholarly treatment of Mexico’s coastal public domain establishes several foundational propositions with direct practical application. Jorge Fernández Ruiz, in Administrative Law and Public Administration (Institute of Legal Research, UNAM), situates the ZOFEMAT within the classical doctrine of public domain: assets subject to a special legal regime that permanently precludes their integration into private patrimony, regardless of the instruments through which possession was acquired. Gabino Fraga, in his foundational Administrative Law (Editorial Porrúa), established that the inalienability of federal public domain assets is a principle that cannot be derogated by administrative act or contract—a point with immediate operational relevance when evaluating private development agreements that purport to grant exclusive beach access or restrict use of federal land. Alfonso Nava Negrete, in Mexican Administrative Law (Fund for Economic Culture), provides the analytically most precise characterization of the concession as an administrative authorization conferring a precarious, conditional right of use—not a property right—whose revocation does not generate constitutional indemnification obligations. Raúl Brañes Ballesteros, in Manual of Mexican Environmental Law (Fund for Economic Culture / Mexican Foundation for Environmental Education, 2nd ed.), documents the structural fragility of Mexico’s coastal environmental regulatory framework: the multiplication of instruments without a coordinating mechanism produces systematic gaps that allow significant coastal degradation to occur even within formal compliance structures.

From a litigation and transactional risk perspective, the principal legal gaps and vulnerabilities in the current regime include:

• the absence of a mandatory federal buffer zone landward of the 20-meter ZOFEMAT, leaving adjacent private development subject to inconsistent local discretion and creating the conditions for gradual encroachment;
• the continuous displacement of the line of ordinary maximum high tide by coastal erosion, dune migration, and climate-driven sea level dynamics, generating recurrent and costly cadastral disputes that the 1991 Regulation provides no mechanism to resolve, and which SEMARNAT has not addressed through any binding technical criterion or administrative resolution establishing a uniform methodology for Quintana Roo;
• the lack of a unified, publicly accessible national registry of ZOFEMAT concessions, which impedes effective due diligence in coastal asset transactions and allows multiple parties to hold conflicting use claims over the same federal area;
• unresolved jurisdictional conflicts between SEMARNAT, PROFEPA, FONATUR, SEDATU, and state and municipal authorities, which are routinely resolved through administrative litigation before the Federal Administrative Justice Court rather than through institutional coordination;
• the legally uncertain treatment of permanent structures on ZOFEMAT land under expired or revoked concessions, where the Regulation’s reversion clause is inconsistently enforced and contested in amparo proceedings; and
• the interaction between ZOFEMAT concessions and agrarian rights in areas where ejidal land adjoins or overlaps with the federal zone—a scenario of increasing frequency in the Tulum and Costa Maya corridors and one that can generate dual-track litigation in both federal agrarian and administrative courts simultaneously.

Transactional Risk Checklist: Coastal Asset Due Diligence in Quintana Roo

Any sophisticated due diligence process for a coastal asset in Quintana Roo must specifically address each of the following risk categories. The existence of a ZOFEMAT concession instrument in a transaction file is a starting point, not a conclusion.

• Concession standing and currency: Confirm the concession is in force, that annual LFD fee obligations under Articles 232-B et seq. are current, and that no revocation or enforcement proceeding is pending before SEMARNAT, PROFEPA, or the Tribunal Federal de Justicia Administrativa. Obtain a certified extract of the concession file from DGZFMTAC.
• Georeferenced boundary verification: Commission an independent georeferenced ZOFEMAT survey prepared by a certified federal surveyor, comparing the current physical shoreline and línea de pleamar máxima ordinaria against the coordinates registered in the concession instrument. Identify any gap between authorized coordinates and physical occupancy, including any structures outside or beyond the concession perimeter. Do not rely on cadastral records or notarial boundary descriptions as substitutes for an independent survey.
• Authorized use conformity: Verify that all structures and activities present on the federal zone correspond to the authorized use description in the concession. Structures built in excess of the authorized footprint, or uses inconsistent with the granted category, constitute independent grounds for revocation regardless of fee compliance.
• Concession term and investment horizon alignment: Assess whether the remaining concession term, and any renewable extensions available under the Reglamento, are consistent with the investment and financing horizon. Terms of five to fifteen years create refinancing and exit constraints that must be addressed in transaction documentation.
• Transfer authorization timeline and deal structuring: Evaluate SEMARNAT transfer authorization requirements under Articles 57 through 60 of the 1991 Reglamento. Model the authorization timeline (typically six to eighteen months in Quintana Roo tourism-classified zones) and establish an interim operating agreement, SEMARNAT no-objection letter as a condition precedent, or purchase price holdback mechanism to allocate the authorization gap risk between buyer and seller. Do not treat SEMARNAT authorization as a post-closing formality in any transaction involving a change of concession holder.
• MIA status and Reglamento compliance: Verify that a valid MIA resolution exists for all works within or affecting the federal zone, issued under the applicable modality pursuant to Articles 5, 6, and 9 through 17 of the Reglamento de la LGEEPA en Materia de Evaluación del Impacto Ambiental (DOF, May 30, 2000). Confirm that construction and operational activities remain within the approved MIA conditions; deviation from MIA conditions is independently actionable by PROFEPA and can support criminal referral.
• NOM-022 and mangrove compliance: Map the asset’s footprint against mangrove and coastal wetland coverage using INEGI and CONABIO cartographic layers. Any evidence of unauthorized mangrove modification triggers NOM-022-SEMARNAT-2003 liability and creates Article 420 Bis CPF criminal exposure for responsible individuals. This analysis must be completed before any acquisition regardless of representations in the seller’s disclosure.
• POET and POEL conformity: Confirm that the project’s footprint, density, height, and use are consistent with the applicable Unidades de Gestión Ambiental under the POET of Quintana Roo and the relevant municipal POEL. Identify any pending modification or challenge to the applicable UGA designation that could affect the asset’s development potential post-acquisition.
• Ejidal boundary interface: In assets in the Tulum, Solidaridad, and Costa Maya corridors, conduct a specific ejidal registry review to identify any overlap or adjacency between federal coastal land and ejidal perimeters. Obtain certified ejidal registry extract and, where overlap is identified, analyze the risk of concurrent agrarian and administrative proceedings.
• Criminal exposure review: Assess whether any existing or historical activities on the asset could support criminal liability under Articles 420 or 420 Bis of the Código Penal Federal. Obtain representations and indemnities from sellers covering pre-acquisition environmental damage and any ongoing PROFEPA investigations that could result in criminal referral to the Fiscalía General de la República.
• Dynamic pleamar baseline risk: Evaluate the asset’s exposure to SEMARNAT baseline recalibration at the next concession renewal, particularly for structures positioned within or near the twenty-meter band. Commission a geomorphological assessment of shoreline change rates at the specific site to quantify the risk that updated delimitation surveys will extend the federal zone boundary inland.
• FONATUR and tourism zone authorizations: In Cancún, the Riviera Maya corridor, and other designated FONATUR zones, confirm the existence and standing of all applicable FONATUR authorizations in addition to SEMARNAT concession instruments. FONATUR authorization deficiencies are not cured by SEMARNAT concession standing and require separate remediation.

IBG Legal: Demonstrated Capability in ZOFEMAT and Coastal Regulatory Practice

IBG Legal has represented clients in PROFEPA enforcement defense proceedings involving unauthorized ZOFEMAT occupation and mangrove damage allegations in Quintana Roo, including proceedings in which the criminal referral risk under Articles 420 and 420 Bis of the Código Penal Federal was a live and actively managed consideration. In the transactional context, IBG Legal conducts independent georeferenced ZOFEMAT surveys as a standard component of pre-acquisition coastal due diligence, combining certified federal survey methodology with legal analysis of concession boundary conformity and dynamic pleamar baseline exposure—a service that institutional lenders and private equity sponsors acquiring resort and hotel assets in the Riviera Maya corridor have engaged specifically to address the boundary and term risk categories described in this article. IBG Legal has also acted in contested concession reversion litigation before the Tribunal Federal de Justicia Administrativa, representing both asset owners resisting federal reversion claims and acquirers seeking to establish the enforceability of transferred concession rights following SEMARNAT authorization disputes.

IBG Legal is headquartered in Cancún with offices in Mexico City and Querétaro.
