Baja California’s housing institute estimates Tijuana alone contains roughly 250 irregular settlements, and new ones are forming “practically every day,” according to INDIVI Director Guadalupe Cuéllar. For anyone considering buying land in Baja, the warning is direct: a signed contract, a fence, and a water hookup do not prove legal ownership. INDIVI (the state’s housing and real estate development institute) is now racing to build an updated registry of these communities, but the data is already outdated before it can be compiled.
Tijuana’s 250 Irregular Settlements Trace Back Decades
Irregular settlements are not new in Tijuana. The city’s explosive growth through the 1980s and 1990s, driven by maquiladora expansion and migration from southern Mexico, pushed families onto hillsides, flood channels, and ejido land (communally held agricultural parcels that require federal authorization to convert to private property). Mexico’s 1992 reform to the agrarian law allowed ejido land to be privatized for the first time, but the process is slow and expensive. Many parcels in the Tijuana metro area remain in legal limbo three decades later.
Today, the pressure has intensified. Tijuana’s formal housing market has tightened as cross-border demand pushes prices upward. Workers earning Mexico’s minimum wage of roughly 375 pesos per day (about $19 USD) cannot qualify for mortgages on homes that now list at 1.5 million pesos ($75,000 USD) or more in legal developments. Informal sellers offer lots for as little as 50,000 pesos ($2,500 USD), often on land they do not legally control.
Two long-running cases show the scale of the problem. In the Rojo Gómez area of Tijuana, a 2011 court ruling left approximately 15,000 families without clear title to the land they occupy. Officials say a regularization process may finally begin soon, but “regularization” is a legal procedure to attempt to create title certainty. It does not guarantee that every family will receive ownership of the parcel they built on.
In Rosarito’s Colonia Morelos, around 500 families purchased lots from an individual who attempted to claim federal land. Those families are now waiting on the outcome of legal proceedings before authorities can even determine whether regularization is possible. Some of those buyers paid in good faith over several years, believing they were building equity in a legitimate purchase.
Improvised Infrastructure Strains Services Beyond Settlement Borders
The effects of irregular settlements extend past their own boundaries. Homes built without planned road grids can block emergency vehicle access to surrounding neighborhoods. Improvised electrical connections, often tapped illegally from CFE (Mexico’s federal electric utility) lines, increase fire risk during Tijuana’s dry, windy Santa Ana season. Hillside construction without proper grading worsens erosion and landslide danger during winter rains.
Unplanned water hookups draw from systems already strained by legal demand. CESPT (Tijuana’s water utility) has struggled with supply shortfalls and infrastructure failures for years. Each unauthorized connection adds pressure that affects service reliability for paying customers in adjacent colonias. If you live near an area with informal development, you may have already noticed lower water pressure or more frequent outages.
Fire response times also suffer. In 2023, Tijuana’s fire department reported that narrow, unpaved roads in hillside settlements regularly prevented trucks from reaching blazes in time. That risk does not stay contained: fires in densely built informal areas can spread to legally titled properties next door.
Five Things to Verify Before Buying Land in Baja
Anyone considering buying land in Baja should treat the process with the same caution they would apply to purchasing property in any unfamiliar legal system. Here are five concrete steps.
First, hire an independent Mexican notario público (a specially licensed attorney, not the same as a U.S. notary) to conduct a title search at the Public Registry of Property. The notario should confirm the seller is the legal owner and the property has no liens. Second, verify the land classification. Ejido land, federal zones (within 20 meters of the coastline or 50 meters of a riverbank), and ecological reserves cannot be sold through a normal private transaction.
Third, confirm the property has a valid catastral (cadastral) number and that property taxes are current with the municipality. Fourth, check permitted land use with the local planning office. A parcel zoned agricultural cannot legally be subdivided for residential lots without a formal reclassification. Fifth, if you are a foreign national, confirm that the purchase is structured through a fideicomiso (a bank trust required for foreigners buying within 50 kilometers of the coast) and that the trust is properly registered.
A seller’s willingness to accept your money is not evidence of legal authority to sell.
INDIVI is currently cross-referencing data from Tijuana’s municipality, federal agencies, and water utilities to determine which settlements can be regularized and which sit on land where legal title may never be possible. No timeline has been announced for completing the updated registry. The story was first reported by Gringo Gazette North.
