Fideicomiso and construction permits explained

A fideicomiso concerns rights to use a property. A construction permit concerns the work you want to carry out. Understanding that distinction helps you ask the right person for each document before starting a home project in Mexico.

What is the restricted zone?

Article 27 of Mexico’s Constitution prevents foreigners from acquiring direct ownership of land and waters within 100 km of international borders and 50 km of the coast. These bands are called the restricted zone. Your advisers should establish the status of the exact property, rather than relying on a destination’s name. See Article 27 of the current Constitution.

For a residential project in Tulum, Cancún, Puerto Vallarta, Los Cabos or Riviera Nayarit, ask a Mexican notario to confirm the acquisition route for the address. When researching San Miguel de Allende or Ajijic, the same principle applies: verify the property and procedure, rather than assuming every foreign purchase follows the coastal model.

How does a bank trust fit in?

The restricted-zone trust route allows a foreign beneficiary to use and benefit from a property through a Mexican credit institution acting as trustee. SRE permission is required and the trust contract is recorded in a public deed. The SRE’s official trust-permission guidance explains the process. Have your notario and bank explain the parties, permitted use, beneficiaries and obligations in your particular deed.

Article 13 of the Foreign Investment Law sets a maximum term of 50 years and allows an extension on request. Renewal is a procedure to discuss with the bank and advisers, not something to assume happens without action. Consult the current Foreign Investment Law, Articles 11–13.

Ask for a written schedule of bank charges, professional fees and government costs. Ask who handles ongoing obligations, changes of beneficiary, transfer or renewal, and what documentation is needed. A construction quote should not be mistaken for the complete cost of acquiring or holding the property.

What about a purchase outside the zone?

The SRE publishes a separate procedure for the foreign buyer’s constitutional agreement outside the restricted zone. Its page identifies the application and supporting documents. Ask your notario to determine the correct route and current requirements for your case. See SRE guidance for property acquisition outside the restricted zone. Avoid using an old downloaded form without checking the official page.

Why a trust does not authorize construction

Property acquisition records do not approve a roof, an extension or a new house. Building authorization is a separate review of the proposal and site. The municipality may need land-use information, drawings and technical documents, with additional approvals depending on the location and work. Confirm this before manufacturing made-to-measure materials or setting a start date.

Puebla’s official licensing information describes a construction license as approval of a proposal that meets applicable technical and urban requirements. Tehuacán maintains its own licensing process. Compare the Puebla construction-license guidance and Tehuacán construction-license page, then contact the authority for the actual address. Their existence is a reminder to check locally, not a permit promise for your project.

Build a document and responsibility checklist

Keep copies of the property documents, relevant acquisition or trust records, approved plans and permits in one folder. Ask your professional team to identify which documents apply, who prepares them, who signs them, their validity and the next action needed. If a contractor says permission is unnecessary, request the basis and confirm it with the competent authority.

Discuss whether a local responsible construction professional is required. Ask who checks changes to the approved design and what close-out documents are needed when the work is complete. Do not assume approval for the main building automatically covers every later structural alteration or addition.

Keep the construction agreement separate and clear

The installation agreement should explain measurements, materials, scope, exclusions, price, payment milestones, access and timing. Request written warranty terms and a change-approval process. Agree how remote progress will be documented and who is authorized to accept the work. These practical arrangements support clearer decisions; they do not replace independent legal review or guarantee an outcome.

VAM can consider aluminum, tempered glass, roofing and drywall projects throughout Mexico, from its Puebla and Tehuacán base. Share the location to confirm project availability and travel arrangements. You can send a written inquiry in English and state your communication preference. VAM is not presented here as a legal adviser, notario, bank trustee or permit-issuing authority.
