4802 W 1st Street, Santa Ana: Prime Mixed-Use Development Site Heads to Auction

Located in the heart of Santa Ana's Riverview West neighborhood, 4802 W 1st Street is a mixed-use parcel with serious development potential. The property sits on 8,712 SF (0.200 acres) and is the key missing piece of a ±18,092 SF assemblage. Paired with the directly adjacent parcel at 4728 W 1st Street, which is available for a concurrent joint closing, the combined site totals 0.415 acres.

At that scale, the assemblage could support a 14–20 unit for-sale townhome development, similar to the product types recently approved just blocks away. Using SB 6 guidelines and a 20–50% density bonus, the site offers a path to a larger project in a high-demand corridor. The listing estimates local for-sale units at $750K to $950K each, for a projected gross sellout of $10.5M to $15.2M. It also puts the combined land basis at about $1.7M and the potential developer profit at $2.5M to $5.0M. These figures are the listing's projections, not guarantees, so buyers should do their own due diligence.

The property is offered at auction with a starting bid of $1,655,000. Bidding begins October 22, 2026, from 8:00 AM to 12:00 PM PST. Electricity and sewer are available, and the water is public.
