A guide to site acquisitions, demolitions and planning approvals in Mexico City

Demolition permits and legal triggers

Under Mexican law, a developer cannot alter or demolish an existing building without explicit authorization from local authorities. In Mexico City, demolition activities fall under the purview of the local administrative boroughs (Alcaldías) in coordination with the Secretariat of Urban Development and Housing (Secretaría de Desarrollo Urbano y Vivienda, or SEDUVI).

The legal trigger for a demolition approval is governed by Article 57 of the Reglamento de Construcciones para el Distrito Federal (RCDF). This regulation specifies that any project involving partial or complete structural clearance, structural dismantling, or deep site excavation requires a Licencia de Construcción Especial para Demolición prior to breaking ground.

To apply for a demolition permit, the site owner or developer must retain a certified Director Responsable de Obra (DRO), a state-licensed architect or civil engineer who assumes legal and technical liability for the site. The DRO submits a comprehensive technical dossier to the relevant borough's Ventanilla Única de Trámites. This submission must include the property deed (Escritura Pública), updated municipal property tax receipts (Impuesto Predial) for the current year, a site safety and demolition procedure plan, and a waste management plan approved by the Secretariat of the Environment (Secretaría del Medio Ambiente, or SEDEMA).

Where demolition occurs concurrently with a new project, the demolition authorization can be integrated into the primary construction notice, known as the Registro de Manifestación de Construcción. However, work cannot begin until the official registry stamp is issued by the borough. Executing demolition without a valid license triggers immediate site closure, heavy administrative fines set under the Código Fiscal de la Ciudad de México, and potential civil or criminal liability for the registered owner.

Heritage and conservation restrictions

Redevelopment sites in historical or established neighbourhoods across Mexico City are frequently subject to strict heritage protections. Federal and local statutory bodies oversee these controls, and their approvals are prerequisites for any proposed modification or tear-down.

Federal jurisdiction is divided between two primary institutions governed by the 1972 Ley Federal sobre Monumentos y Zonas Arqueológicos, Artísticos e Históricos:

1. Instituto Nacional de Antropología e Historia (INAH): Regulates, catalogues, and protects all pre-Hispanic and colonial structures built prior to 1900. Demolition of an INAH-catalogued monument is strictly prohibited under federal law. 2. Instituto Nacional de Bellas Artes y Literatura (INBAL): Holds authority over 20th-century and contemporary architectural heritage. Buildings listed by INBAL cannot be demolished or structurally altered without formal authorization from its Dirección de Arquitectura y Conservación del Patrimonio Artístico Inmueble.

At the local municipal level, SEDUVI oversees Áreas de Conservación Patrimonial (Patrimonial Conservation Zones) defined within the Plan General de Desarrollo Urbano. Sites located within historic enclaves such as Coyoacán, San Ángel, Roma, Condesa, or the Centro Histórico carry secondary zoning restrictions even if the specific building is not individually listed. In these zones, developers must obtain an Dictamen Técnico del Consejo del Patrimonio Urbano Arquitectónico before applying for any permit. If a building is classified with historical value, the law generally requires structural preservation, restricting the owner to internal adaptive reuse or partial rear extensions.

Calculation of buildable area

Buildable area in Mexico City is strictly regulated by SEDUVI through the Certificado Único de Zonificación de Uso del Suelo. This binding document outlines the site zoning code, which dictates land use, maximum floor count, and open space requirements.

Zoning designations appear as structured alphanumeric codes, such as H / 3 / 30 / M. In this example, 'H' denotes Residential land use (Habitacional), '3' dictates a maximum height of 3 storeys above street level, '30' specifies that 30 percent of the total plot must remain unbuilt as open ground (Área Libre), and 'M' defines the permitted residential density.

To establish the exact floor area that can be constructed, developers use two mandatory metrics established in the Normas Generales de Ordenación:

• Coeficiente de Ocupación del Suelo (COS): The maximum footprint of the building at ground level, expressed as a decimal or percentage. COS is calculated by subtracting the required open area percentage from the total plot size. For a 1,000 square metre lot with a 30 percent open space requirement, the maximum ground coverage (COS) is 70 percent, or 700 square metres.
• Coeficiente de Utilización del Suelo (CUS): The maximum total built area across all storeys above ground level. CUS is calculated by multiplying the ground footprint (COS) by the maximum permitted number of storeys. For a 1,000 square metre lot with a 700 square metre COS and a 3-storey limit, the CUS equals 2.1, yielding a maximum gross buildable surface of 2,100 square metres above ground.

Subterranean parking levels do not count toward the CUS total provided they remain completely below natural ground level, subject to local soil and environmental rules.

Tenant rights and site clearance

When purchasing an occupied property for tear-down or redevelopment, buyers must comply with the provisions of the Código Civil para el Distrito Federal regarding lease agreements and tenant possession.

In Mexico City, the sale or transfer of real estate does not automatically invalidate existing lease contracts. The buyer assumes the legal role of landlord under the terms of the active lease. Mexican law contains no automatic statutory right to evict tenants simply because a site has been marked for demolition or redevelopment.

If a tenant is operating under a valid, fixed-term lease, they hold legal right of possession until the expiration date. To clear a site before lease expiry, a developer must enter into a negotiated voluntary surrender agreement (Convenio de Terminación Anticipada). This process almost always requires financial compensation, negotiated privately between the landlord and tenant.

Where a residential or commercial contract has converted to an indefinite or month-to-month tenancy, the landlord must issue formal statutory notice under Article 2478 or Article 2479 of the Civil Code. For residential tenancies, the legal notice period is two months; for commercial tenancies, it is three months. Should a tenant refuse to vacate following formal notice, the developer must initiate judicial eviction proceedings (Juicio Inmobiliario de Desocupación). Litigation in local civil courts can delay site possession by 12 to 24 months.

Costs and timeframes for permitting

Taking a redevelopment site from initial purchase to active construction involves navigating a multi-stage municipal process. The comprehensive permitting phase typically takes between 6 and 12 months, depending on project scale and location.

Key steps and timeline breakdown:

1. Preliminary Certificates (1 to 2 months): Securing the Certificado Único de Zonificación de Uso del Suelo and the Constancia de Alineamiento y Número Oficial from SEDUVI and the local borough. 2. Utility and Environmental Approvals (3 to 5 months): Acquiring water supply feasibility clearance (Dictamen de Factibilidad de Servicios Hidráulicos) from the Sistema de Aguas de la Ciudad de México (SACMEX), alongside environmental impact assessments from SEDEMA if required. 3. Technical Registrations (2 to 3 months): Review of structural plans by the Instituto para la Seguridad de las Construcciones and formal filing of the Manifestación de Construcción Tipo B (for residential up to 10,000 sq m) or Tipo C (for large-scale or mixed-use over 10,000 sq m).

Government filing fees are calculated under the 2026 Código Fiscal de la Ciudad de México based on proposed square meterage. Statutory fees for a Manifestación de Construcción Tipo B or C generally range from 35,000 MXN to over 200,000 MXN for large commercial builds. Third-party professional fees, including hiring a licensed DRO, structural checkers (Corresponsables de Seguridad Estructural), and environmental consultants, typically add between 300,000 MXN and 1,500,000 MXN to pre-construction soft costs depending on technical complexity.

Local zoning rules, municipal tax rates, and administrative procedures in Mexico City remain subject to statutory updates by SEDUVI and the local legislature.
