29 Tulum Developments Flagged by the Government — Is Yours on the List?

By Nick Neacsu, Sales Manager — Engel & Völkers Tulum  |  April 2026

If you're considering buying property in Tulum, this is one of the most important articles you'll read before making a decision. The Secretaría de Desarrollo Territorial Urbano y Sustentable (SEDETUS),  Quintana Roo's official urban development authority, maintains a public registry of real estate projects that are operating without the required government permits. As of April 2026, 29 developments in the Tulum municipality appear on that list.

At Engel & Völkers Tulum, transparency is at the core of everything we do. As Sales Manager, It's my job to make sure buyers have access to information that protects their investment, not just the glossy brochures developers hand out at sales events. Below, I break down every flagged project, why they were flagged, and what this means for you as a buyer.

🔍 What Is the SEDETUS Registry?

SEDETUS publishes the Registro Estatal de Desarrollos Inmobiliarios Irregulares, a searchable public database of real estate projects in violation of state and municipal law. You can check it yourself here: desarrollo.sedetus.gob.mx/consultaDesarrollos

This registry is a critical due-diligence tool for anyone looking to invest in property in Quintana Roo, and most buyers have never heard of it.

⚖️ Why Are These Developments Flagged?

Every single one of the 29 Tulum developments on this list shares the same legal violation:

"Contravienen los artículos 80 y 81 de la Ley de Asentamientos Humanos Ordenamiento Territorial y Desarrollo Urbano del Estado de Quintana Roo, toda vez que se encuentran realizando actividades de publicidad y difusión en cuanto a su comercialización, sin contar con la Constancia de Congruencia Urbanística Estatal, licencias o permisos de índole municipal inherentes a los mismos."

In plain English: These developments are actively advertising and selling properties to the public without having obtained the legally required State Urban Congruence Certificate (Constancia de Congruencia Urbanística Estatal) or the necessary municipal licenses and permits, a direct violation of Articles 80 and 81 of Quintana Roo's Land Use and Urban Development Law.

Simply put: they are collecting your money before the government has approved their project.

🚨 What Are the Risks of Buying in a Flagged Development?

1. No legal protection — Without proper permits, the development may never receive municipal approval. Your unit could never be legally titled in your name.
2. Construction can be halted — Authorities can stop work at any time, leaving your project unfinished with no recourse.
3. No fideicomiso guarantee — Without official permits, you may not be able to secure a proper fideicomiso (bank trust), the legal mechanism foreign buyers use to hold property in Mexico's restricted zones.
4. Nearly impossible to resell — A property with a cloudy legal title is extremely difficult to resell or refinance.
5. Loss of your entire investment — In the worst cases, buyers have lost every peso they put in.

✅ How to Buy Safely in Tulum

Not all Tulum developments are flagged, there are many legitimate, fully permitted projects in the market. Here's how to protect yourself before signing anything:

1. Check the SEDETUS registry first — desarrollo.sedetus.gob.mx/consultaDesarrollos
2. Request the Constancia de Congruencia Urbanística Estatal — any legitimate developer will have this document and will hand it over without hesitation.
3. Hire an independent notary and real estate attorney — not one recommended by the developer.
4. Understand the fideicomiso process — watch the guide above and work only with a reputable Mexican bank.
5. Work with a trusted advisor — I only present fully vetted, legally compliant developments to my clients.
