In San Miguel de Allende, “permiso de venta” is the phrase buyers should learn early. The mayor says that one document can separate a real project from an expensive mirage. Why? Because it is issued only after key paperwork and guarantees are in place, it leaves a trail in the public record. Yet many buyers—especially those shopping from abroad—never ask for it until after the money has changed hands. What does the permit actually prove, where should it show up, and what other red flags tend to appear first? Here’s the practical checklist behind the warning.
A warning that starts with one document
San Miguel de Allende’s mayor, Mauricio Trejo, is telling buyers to slow down. Don’t fall in love with a brochure first. He warned that some projects have been marketed, and even “sold,” without a municipal sales permit. That permit is required before lots or units can be transferred legally. The warning was aimed at locals and foreigners alike. Both groups have been burned in earlier fraud cases. Trejo says the city has tightened oversight, yet he insists prevention starts with buyers. Scams often begin with urgency. Think limited-time pricing, a “last unit,” or a pushy request for a deposit. For many expats, the risk is distance. You might tour a site once, then sign from another city or another country. A sales pitch can move faster than the municipal file. Ask early, before you pay. Trejo’s point: if you can’t see the permit, treat it as a stop sign, not a speed bump.
What a permiso de venta really means
In San Miguel, the permiso de venta is not marketing fluff. It is a municipal authorization tied to specific plans, lots, and obligations. Local rules allow a developer to request it only after urbanization work has begun. The same applies once a condominium project is under active construction. To get it, the developer must present a certificate showing liens and any related approvals. They also need proof of donated public areas and streets, as well as evidence of required payments. The city can require a financial guarantee to complete missing infrastructure. The permit is not meant to sit in a drawer. It must be registered with the local Public Registry and published in the state’s official gazette and a local paper. That paper trail matters because it is harder to fake and easier to verify. The rules also draw a bright line. Without a permiso de venta, developers are prohibited from signing deals that transfer ownership. If someone wants money first and paperwork later, the law treats that as a red flag.
Why the warning resonates in San Miguel
San Miguel’s appeal is a magnet for new construction, and that speed creates openings for bad actors. Many buyers shop by the calendar, not by a checklist. They want a place before high season, or before prices climb again. That urgency is amplified for expats who buy from afar, often through messaging apps and quick site visits. In recent years, the city has faced disputes tied to projects that moved ahead before urban planning was complete. The fraccionamiento Ciudades Unesco became a visible example. Local officials said it was closed due to failing conditions and urged affected buyers to seek guidance. The common pattern is simple. Payments are collected early, while permits and infrastructure lag behind. When deadlines slip, buyers discover they lack leverage, or even a clear legal path. That is why the mayor’s warning lands now. A permit check is not pessimistic. It is how you tell the difference between a delayed project and a project that should never have been sold.
A safer way to shop for property from abroad
Start by asking to see the permiso de venta and the project’s land-use and construction authorizations. Mexico’s federal consumer standard for housing sales requires providers to hold those permits and share them with consumers. A serious developer will show you documents that match the exact address and company name. Next, look at the contract, not the rendering. It should include a PROFECO registration number for the model contract. You can cross-check that number in PROFECO’s Registro Público de Contratos de Adhesión. If you’re buying in pre-sale, insist on clear delivery dates and penalties for delays. Make sure the contract describes finishes and common areas in plain language. Then bring in the right local professional. In Mexico, searches by the notary and the Public Registry often turn up surprises, including liens and ownership gaps. If any step becomes excuses, missing pages, or pressure to wire money “today,” take it as a sign. Walking away is cheaper than litigation.
