To verify that a Tulum development is legal, do five things: ask for its permit file (expediente), check the state's SEDETUS bulletins, confirm the title path with an independent notary, search the Registro Público de la Propiedad, and review the developer's completed projects. This checklist walks through each step — including what happened when the state reviewed our own project in September 2025.
We are a developer writing about developer verification, so let us put our cards on the table first. Selvadentro appeared on a state alert, and was removed five days later after proving compliance. We tell that story below with dates and sources, because it is the clearest worked example we know of the system doing its job.
What is SEDETUS and why does it matter?
SEDETUS — the Secretaría de Desarrollo Territorial Urbano Sustentable de Quintana Roo — is the state authority that oversees urban development. It reviews whether projects hold the state and municipal authorizations they need, and it publishes its findings openly. For a buyer, that makes it something rare in real estate: a public, official, free source you can check yourself.
What happened in September 2025 — including to us
On September 11, 2025, SEDETUS published an alert listing 26 Tulum developments that allegedly lacked state or municipal permits. Selvadentro was on that initial list. The alert was covered by local press, including El Quintanarroense and later Reportur.
On September 16, 2025, SEDETUS published an updated bulletin removing 14 developments — Selvadentro among them — after they demonstrated full compliance with the Ley de Asentamientos Humanos, the Ley de Acciones Urbanísticas, the Ley de Propiedad en Condominio, and related regulations. Tulum Times reported it under the headline "SEDETUS Clears 14 Tulum Developments After Legal Review" (September 2025).
Two honest takeaways. First, the review worked exactly as it should: the authority asked, we presented the expediente, the record was corrected within five days. Second — and this is the part that matters for you — 12 developments were not cleared. A market where the state actively audits projects is a market where checking before you buy is both possible and worth doing.
The verification checklist: how do you check any Tulum development?
Run this on any project — ours included. It costs you a few days and protects a six-figure decision.
- Ask for the expediente. Every legitimate development can hand you its file: dictámenes (technical opinions), constancias, land-use authorizations, and state and municipal permits. Ask for copies, not a glance at a binder.
- Check the SEDETUS bulletins. Search the developments SEDETUS has flagged and cleared, and ask the developer directly whether the project has ever appeared in one — and how it was resolved. The September 2025 cycle shows both lists exist.
- Verify the escritura path with an independent notary. Before signing anything, have a notario público of your choosing — not the seller's — confirm how and when you will receive title: the deed, the condominium regime, and for foreign buyers the fideicomiso setup.
- Search the Registro Público de la Propiedad. Confirm the land is registered, who actually owns it, and that it is free of liens. A property that cannot be found in the registry cannot be legally transferred to you.
- Verify the developer's completed projects. Track records are checkable: visit past developments, confirm they were delivered and titled. Our own principals' record — Aldea Zamá in Tulum and Yucatán Country Club in Mérida — is documented here.
Which red flags should stop you?
| Red flag | What it usually means |
|---|---|
| "The permits are in process" with no dates or documents | The project may be selling before it is authorized |
| Refusal to hand over the expediente | There may be nothing complete to hand over |
| Pressure to sign before due diligence | The seller benefits from you not checking |
| Only a private contract, no notary or escritura path | You may be buying paper, not property |
| Price dramatically below the area with no explanation | Risk is being discounted into the price |
| No completed, verifiable projects behind the developer | You are financing a first experiment |
None of these is a verdict on its own. Two or more together, and you should walk.
The green flags are the mirror image: copies of the expediente handed over without friction, a seller who suggests you bring your own notary, a registered condominium regime, and delivered projects you can stand inside. Verification matters most in pre-construction, where you pay before the product exists — if that is your route, read our pre-construction guide alongside this checklist, because price advantage only makes sense on top of proven paperwork.
What this means at Selvadentro
We keep our compliance documentation available to any prospective buyer — the expediente, the condominium regime, and the September 2025 clearance with its dates. Our legal compliance page summarizes it, and our team will put the documents in front of you before you are asked to sign anything. We also think you should read the broader question honestly: is it safe to buy property in Tulum? The answer is yes — if you verify.
If you are comparing developments right now, use the checklist above on every one of them. And if Selvadentro is on your list, start with current lot availability or the FAQ, and ask us for the file. We would rather you buy slowly and certain than fast and worried.
