Rosarito’s population grew 40 percent in a single decade. Its roads, sewers, and water systems did not. The gap between the city’s booming real estate market and its strained utilities now defines daily life for residents and expats alike, making Rosarito infrastructure growth one of the most pressing issues on the Baja coast.
The coastal city recorded 126,890 residents in the 2020 census. That figure has only climbed since, driven by continued migration from the United States and other parts of Mexico. Condos and housing developments have spread across hillsides and corridors that, in many cases, still lack basic services. The city government acknowledged the mismatch by launching a Plan Integral de Movilidad Urbana Sustentable, known as PIMUS. This comprehensive mobility plan aims to reorganize traffic flow, improve transit, and address what officials call the city’s “most sensitive urban problems. “
How Rosarito Infrastructure Growth Fell Behind
Rosarito’s infrastructure deficit did not appear overnight. The city incorporated as its own municipality only in 1995, separating from Tijuana. For years it operated with a fraction of the tax base and institutional capacity of its larger neighbor. As American retirees and remote workers discovered affordable oceanfront living, development outpaced the city’s ability to deliver services.
The numbers tell the story clearly. Baja California’s most recent government report puts sanitary sewer coverage in Rosarito at just 70.40 percent as of October 2024. Tijuana, by comparison, sits at 90.10 percent. That 20-point gap means nearly one in three Rosarito households lacks a proper sewer connection. The state government listed active sewer expansion projects in neighborhoods including Colinas del Sol, Catalina del Mar, Cumbres del Mar, and Villaurrutia.
Roads present a similar challenge. Many streets remain unpaved, generating dust, accelerating vehicle wear, and slowing emergency response. A sinkhole on Heinse Boulevard grew serious enough to become an urgent municipal rehabilitation priority. NADBank, the North American Development Bank that finances border infrastructure projects, has funded paving work in Rosarito. The bank says these projects should reduce peak-hour congestion and lower particulate pollution.
However, the pace of remediation trails the pace of growth. New developments continue to receive permits while surrounding infrastructure remains incomplete. This pattern is familiar across fast-growing Mexican municipalities. Local governments depend heavily on state and federal funding for major capital projects. Municipal budgets cover maintenance and modest improvements, not transformative upgrades.
What This Means for Expats and Property Owners
For the growing English-speaking community in Rosarito, infrastructure gaps create real friction. The most immediate pain point is traffic. Anyone who has driven Benito Juárez Boulevard on a weekend knows the crawl. Census data show 57.2 percent of Rosarito workers rely on personal vehicles. Average commutes stretch to 24.5 minutes. In a city with few alternative routes and no public transit system worth the name, congestion compounds fast.
Water reliability is another concern. Rosarito sits within the same strained water system that serves greater Tijuana. The region depends on Colorado River allocations delivered through CONAGUA, Mexico’s national water commission, and local supply has not kept up with demand. A long-discussed desalination plant for Rosarito recently cleared key hurdles. The state government secured 656.1 million pesos in support from FONADIN, the federal infrastructure trust fund, for land acquisition and preliminary studies. For more on the regional water picture, see BDN’s guide to Baja California’s water crisis, desalination plans, and what expats should know.
Property values are directly tied to infrastructure quality. A condo with ocean views loses appeal if the street floods during winter rains or sewer service is unreliable. Resale becomes harder when buyers can see unfinished roads and smell drainage problems. Neighborhoods with completed upgrades hold value better. Those still waiting carry risk that is difficult to price.
Specifically, expats considering purchases in Plan Libertador, Lomas de Coronado, Lomas de Rosarito, or Primo Tapia should know these areas appear on the city’s 2026 priority public works list. That signals both current deficiencies and planned investment.
Government Response at Three Levels
Rosarito’s municipal government approved a 2026 public works program targeting roads, stormwater drainage, public spaces, and the problem corridors listed above. At the state level, Baja California continues expanding sewer connections and advancing the desalination project.
At the federal level, the response is larger but slower. President Claudia Sheinbaum’s administration announced a 37 billion peso infrastructure package for Baja California in January 2026. The package includes road projects and other strategic investments. CONAGUA has designated the Rosarito desalination plant as a major regional water project.
The question is timing. Federal infrastructure packages take years to flow into local contracts. The desalination plant remains in the study phase. Meanwhile, new residents keep arriving and new buildings keep rising.
Rosarito’s appeal is real: the ocean, the proximity to San Diego, the lower cost of living. But the city is in a race between development and the systems that make development livable. If you own property here or plan to buy, the neighborhood-level infrastructure picture matters as much as the view. Watch the 2026 public works schedule closely. The projects that actually break ground this year will shape which parts of Rosarito deliver on their promise and which ones keep waiting.
