Costa Mesa Approves Housing on a Former State Hospital Site. What Surplus Public Land Could Mean for San Diego Buyers

A former state hospital site is set to become housing. According to the Los Angeles Times, Costa Mesa has approved a large-scale housing development on the former Fairview Developmental Center campus. The site was a state-run facility for decades, and the approval moves it from institutional use toward homes.

The project matters beyond Orange County because of where the land came from. Most new housing in coastal Southern California has to squeeze onto small infill lots, often one parcel at a time and often against strong neighborhood opposition. A single large campus that is already owned by the public changes that math. It can take years of planning, but once approved it can deliver far more homes than scattered lot-by-lot building.

Why San Diego should pay attention. San Diego County has the same basic problem as Orange County: strong demand, limited land, and a coastline that caps how far the region can spread. It also has its share of underused public and institutional property, including aging government facilities and large parcels held by agencies. Costa Mesa's approval is a useful example of how a coastal city can open a new source of supply without rezoning established single-family streets.

For buyers, more supply in the region is good news, but it arrives slowly. Large redevelopment sites typically build out in phases over several years, so any effect on prices will be gradual and local. Buyers shopping in San Diego today should not wait on projects like this one. The better move is to track which large sites are entering the planning pipeline near the neighborhoods you are considering, since those plans can shape traffic, schools, and retail over the next decade.

For owners, a nearby project of this scale can cut both ways. New residents often bring new shops, services, and infrastructure investment, which tends to support values in established streets close by. Construction periods and added density can also test patience. The details of each plan (open space, road improvements, and the mix of for-sale and rental homes) decide which way it tips.

Our view. Southern California will not solve its housing shortage one lot at a time. Reusing large public sites is one of the few paths that can add meaningful supply in coastal counties, and Costa Mesa has now shown that it can get through approval. Our team watches these pipelines closely in San Diego so clients know what is coming to a neighborhood before it shows up on the market.
