Here is the honest answer up front: you can own a beachfront home in Mexico as a foreigner, but you can never own the beach itself or the 20-meter federal strip between your lot and the water. That strip is the ZOFEMAT (Zona Federal Marítimo Terrestre), and along with the beach it belongs to the Mexican nation as public-use property. What you can hold is title to the upland lot, through a bank trust, plus a separate government concession to use the federal strip in front of it. Those are two different rights, and confusing them is where buyers lose money.
This is one of the most common questions we get at City Laws from buyers coming from the United States and Canada. Back home, “beachfront” usually means your deed runs to the mean high-tide line and the sand is yours. Mexico works the opposite way: the closer you get to the water, the less any private title can reach. Below is what you can and cannot buy, what the law says, and the traps a good real estate lawyer in Mexico checks before you close.
The restricted zone: why a foreigner cannot hold direct title on the coast
Article 27, fraction I, of the Mexican Constitution draws a line around the country’s edges. Within a band of 100 kilometers along the borders and 50 kilometers along the coastline — the zona restringida (restricted zone) — foreigners cannot acquire direct ownership (dominio directo) of land or water. Only Mexican nationals and companies may, or foreigners who first agree before the Secretaría de Relaciones Exteriores (SRE) to be treated as nationals as to that property and not to invoke their home government’s protection over it — the commitment known as the Calvo clause.
Every meter of coastline sits inside that 50-kilometer band, so for a US or Canadian beach buyer direct ownership is off the table. What is on the table is a well-established mechanism the law itself created.
The fideicomiso: how foreigners legally hold beachfront homes
Under the Ley de Inversión Extranjera (Foreign Investment Law), a foreigner can hold residential real estate in the restricted zone through a bank trust, or fideicomiso (articles 10 and 11). A Mexican credit institution holds legal title as trustee (fiduciaria), and you, the foreigner, are the beneficiary (fideicomisario), with the full bundle of practical rights — to use, live in, rent, remodel, sell, and pass the property to your heirs — without holding a derecho real (real property right) over the land itself.
Two points matter most for planning:
- The bank needs an SRE permit. Article 11 requires a permit from the Secretaría de Relaciones Exteriores for the institution to act as trustee over restricted-zone property for a foreign beneficiary, and the property must be residential.
- The 50-year term is renewable, not a cap on your ownership. Article 13 sets a maximum term of fifty years, but says it “may be extended at the interested party’s request” (podrá prorrogarse a solicitud del interesado). This matters because of a persistent myth: the fideicomiso is not a 50-year clock that ends your ownership. It renews indefinitely in 50-year terms and passes to your heirs.
A fideicomiso is not a lease and not a loophole. It is the mechanism the Constitution and the Foreign Investment Law built so foreigners can hold coastal homes, with real, durable rights to use, rent, sell, and inherit.
What the ZOFEMAT actually is
Now to the strip that trips buyers up. The ZOFEMAT is defined in article 119 of the Ley General de Bienes Nacionales (General Law of National Assets). As a general rule, it is a 20-meter-wide band of firm, transitable land adjacent to the beach. The law sets out variants for unusual coastlines:
- Along rivers, the zone runs 100 meters upstream from the mouth.
- Cays and reefs are ZOFEMAT in their entirety.
- For lakes, lagoons, and estuaries connected to the sea, it is measured from the highest annual tide or flood line.
- In artificial marinas and canals, it may be reduced to no more than 3 meters.
On rocky or cliff coasts without a beach, the 20 meters is measured from the shoreline where the slope does not continuously exceed 30 degrees. The on-the-ground delimitation is performed by SEMARNAT following NOM-146-SEMARNAT-2017 and the federal regulation on the use of beaches, ZOFEMAT, and land reclaimed from the sea.
You cannot buy the beach — from anyone, ever
Both the maritime beaches and the ZOFEMAT are bienes de uso común — public-use national assets — under article 7, fractions IV and V, of the General Law of National Assets. Article 13 makes them property of the federal public domain and declares them inalienable, imprescriptible, and unseizable (inembargables): they cannot be sold, mortgaged, or acquired by adverse possession, by anyone — Mexican or foreign.
So when a seller unrolls a site plan showing “your” lot running to the water’s edge, the beach and the 20-meter strip on it are not part of any private lot, no matter what the drawing says, and nobody can grant you private title to them. This is the opposite of the US rule, where in many states a deed runs to the mean high-water mark and the dry sand can be privately owned.
| What you are looking at | Can a foreigner “own” it? | Correct legal vehicle |
|---|---|---|
| Upland beachfront lot (restricted zone) | Yes — beneficial ownership | Bank trust (fideicomiso) with SRE permit |
| The maritime beach | No — public domain, never | None; open to common public use |
| The 20-meter ZOFEMAT strip | No ownership — only use rights | SEMARNAT concession |
| US/Canada comparison | Deed often runs to high-tide line | Private deed (does not apply in Mexico) |
The concession: how you legally use the federal strip
If the beach and ZOFEMAT can’t be owned, how does a resort put a dock, a palapa, or a pool on that strip? Through a concession. Article 120 of the General Law of National Assets puts SEMARNAT in charge of administering the ZOFEMAT, through its Dirección General de Zona Federal Marítimo Terrestre y Ambientes Costeros (DGZFMTAC); PROFEPA verifies compliance.
A concession may be granted for up to 50 years and extended one or more times; under article 73, the holder has a preferential right to request renewal during the final 10% of the term. Crucially, it grants use and exploitation rights, not ownership. Holders must also pay annual federal fees (derechos) under article 127 and the Ley Federal de Derechos, and non-payment or unauthorized occupation can lead to cancellation and PROFEPA sanctions.
Foreigners can obtain ZOFEMAT concessions, but as with any concession touching article 27 they are bound by the Calvo-clause commitment; in practice, foreign buyers commonly channel beachfront concession rights through a Mexican fideicomiso or financial institution rather than holding them directly.
The trap that costs buyers: the lot does not include the concession
This is the single most important practical point in this article. Owning the upland lot through a fideicomiso does not give you the ZOFEMAT concession for the strip in front of it. The concession is a separate federal title that must exist, be current, and be transferred or assigned to you. A lot marketed with “private beach access” is worthless as a beach right if no valid concession backs it, or if it sits in someone else’s name and is never assigned to you.
Before you close, insist on seeing and verifying:
- Proof the seller or developer holds a valid, current ZOFEMAT concession for the exact strip in front of the lot — SEMARNAT publishes concession titles for consultation.
- That the concession is paid up, with annual derechos current, so it is not exposed to cancellation.
- How the concession will be transferred or assigned to you at closing, and whether SEMARNAT approval is required.
- The official ZOFEMAT delimitation, so you know where the federal strip begins and how much of the “beach” the seller shows you is actually public domain.
The consumer-protection layer: buying from a developer
If you are buying pre-construction or from a developer, one more body of law applies. Developers, builders, promoters selling housing to the public, and time-share operators fall under Profeco. Under articles 73 and 73 BIS of the Ley Federal de Protección al Consumidor, they must register their adhesion contracts with Profeco, meet pre-sale (preventa) disclosure duties, and provide minimum warranties — roughly five years for structural elements, three for waterproofing, and one for other components. Asking whether the contract is registered with Profeco is a fast screening question.
Is the 20-meter strip about to shrink? What buyers should know
You may see claims online that the ZOFEMAT is being cut from 20 meters to 10. An initiative to amend article 119 to that effect advanced in the Senate, but it remains pending in the Chamber of Deputies and has not been published in the Diario Oficial de la Federación. As of 2026, the ZOFEMAT is still 20 meters — treat the change as a proposal to watch, not current law. The Foreign Investment Law’s most recent reform (DOF, May 27, 2024) did not touch the restricted-zone or fideicomiso rules, so the bank trust works the same in 2026 as before.
Frequently asked questions
Can I actually own beachfront property in Mexico as an American or Canadian?
Yes — the upland home, through a bank trust (fideicomiso) authorized by the SRE, giving you full rights to use, rent, sell, and inherit. What you cannot own is the beach or the 20-meter federal ZOFEMAT strip, which are public domain and cannot be sold to anyone.
What is the difference between the fideicomiso and the ZOFEMAT concession?
They cover different ground. The fideicomiso is how you hold the private upland lot in the restricted zone. The ZOFEMAT concession is a separate federal permit from SEMARNAT to use the 20-meter strip between your lot and the water. Owning the lot does not automatically include the concession — you must verify it and, if needed, have it assigned to you.
Does the 50-year fideicomiso mean I lose the property after 50 years?
No. Article 13 of the Foreign Investment Law sets a maximum 50-year term that “may be extended at the interested party’s request.” It renews indefinitely in 50-year terms and passes to your heirs — it is a renewal cycle, not an expiration of your ownership.
The seller’s site plan shows the beach as part of my lot. Is that legal?
The drawing may be misleading. Under articles 7 and 13 of the General Law of National Assets, the beach and the ZOFEMAT are federal public property and cannot be part of any private lot. Any beach use comes from a SEMARNAT concession, not the lot’s title.
