Baja California Sur Governor Víctor Manuel Castro Cosío announced this week that the state may stop issuing permits for new real estate developments in La Paz and Los Cabos unless developers can prove adequate water supply. The proposal, made during a Mañanera del Pueblo press briefing, would create an intergovernmental working group to draft legal reforms. No formal moratorium has been declared, and no legislation has been drafted yet. But the governor’s language was unusually direct for a state that has spent two decades courting foreign investment.
“We have to take a firm, legal decision and say: enough,” Castro Cosío said. “Water for everyone comes first.”
BCS Development Permits Water Crisis Dates Back Over a Decade
Water scarcity in Baja California Sur is not new. The state is the driest in Mexico, receiving an average of just 170 millimeters of rainfall per year. Los Cabos and La Paz both depend on underground aquifers that CONAGUA, Mexico’s national water commission, has classified as overexploited since at least 2013. OOMSAPAS, the Los Cabos municipal water utility, has struggled to deliver consistent service to colonias across the corridor between San José del Cabo and Cabo San Lucas.
Protests over water access in Los Cabos have grown more frequent since 2021. In some neighborhoods, residents report going days without tap water during peak tourist season, when hotel and resort demand spikes. La Paz faces similar pressure. Where single-family homes once stood in neighborhoods like Esterito, condominium towers now rise, each one drawing from the same strained municipal system.
Desalination has been discussed as a solution for years. A small desalination plant operates in San José del Cabo, but its output covers only a fraction of demand. A larger plant proposed for La Paz has faced repeated delays in financing and permitting. Castro Cosío’s proposal essentially acknowledges that infrastructure has not kept pace with construction approvals.
The pattern is familiar across Mexican resort markets. Cancún and Playa del Carmen on the Yucatán Peninsula faced a similar reckoning in the early 2020s, when the state of Quintana Roo began requiring environmental impact statements that specifically addressed water supply for new tourism developments. Puerto Vallarta has debated comparable restrictions as its condo market expanded into hillside zones with limited water access. In each case, the tension was the same: municipal governments depended on permit revenue, while state and federal agencies flagged resource limits.
Existing Permits Likely Safe, but New Projects Face Uncertainty
Castro Cosío acknowledged that property owners currently have a legal right to build if they hold proper municipal permits. His proposal would not retroactively cancel those approvals. Projects already under construction or holding valid permits would likely proceed without interruption.
The change would target new applications. Under the governor’s framework, developers would need to demonstrate that their projects will not worsen local water shortages. That standard goes beyond existing zoning and environmental requirements, which do not currently make water availability a primary criterion for permit approval.
For investors with projects in the planning phase, the practical impact could include longer approval timelines, additional documentation requirements, and the possibility of outright denial in areas where aquifer levels are critically low. Municipal governments in La Paz and Los Cabos, which currently control construction permits and depend on application fees for revenue, would need to coordinate with the state government on new standards.
The governor proposed forming a working group with the State Congress and both municipal governments to draft the legal reforms. He offered no timeline for when that group would convene or when legislation might reach the floor.
Property values in Los Cabos and La Paz could face mixed effects. A development slowdown could constrain supply in an already tight market, supporting prices for existing properties. At the same time, regulatory uncertainty tends to cool investor enthusiasm. The short-term rental market, which has grown rapidly across both cities, relies on a steady pipeline of new condo inventory to feed platforms like Airbnb and Vrbo.
Castro Cosío Links Water Scarcity to Gentrification Concerns
The governor framed his proposal as both a resource issue and a social one. He pointed to rising housing costs that have priced local families out of neighborhoods now dominated by vacation rentals and luxury developments.
“Everywhere you go, construction is sprouting up,” Castro Cosío said. “This has to be regulated.”
That language reflects a broader debate across Baja California Sur about who benefits from the state’s real estate boom. Construction has generated jobs and tax revenue, but working-class residents in La Paz and San José del Cabo increasingly compete for housing with foreign buyers and short-term rental operators willing to pay in dollars.
The governor’s dual framing, tying water access to housing affordability, could build a wider coalition of support than a purely environmental argument. But it also raises the political stakes. Municipal officials who rely on construction permits for revenue may resist a state-level framework that limits their authority to approve projects.
The working group has not yet been formally convened. Castro Cosío said the details, including how water availability would be measured for individual projects and who would enforce the new standards, remain to be defined through the legislative process. The proposal was first reported by Diario El Independiente.
