4090 C St, San Diego, CA 92102

40th & C Street offers a rare, fully entitled residential development opportunity in the heart of Southeastern San Diego. The 2.12-acre property is approved for a thoughtfully designed 29-unit community consisting of single-family residences and accessory dwelling units, delivering an efficient and highly desirable housing product in a supply-constrained market. The project offers flexible exit strategies, allowing an investor or developer to deliver a build-to-rent community or sell the completed finished units/lots individually upon completion. The development is planned across ten lots, with nine lots entitled for one single-family home with two ADUs each, and a tenth lot entitled for two single-family homes, resulting in a total of 29 units.The property has completed an extensive multi-year entitlement and subdivision process, including the vacation of three previously un-developable public streets and a portion of an alley, followed by land consolidation, subdivision, and full development permit approvals. The project was ultimately reviewed by both the Planning Commission and the City Council, where it received unanimous final approval in December 2025. The project is fully entitled and vested, with approvals that are no longer subject to appeal. The CEQA determination has also vested and is no longer subject to legal challenge, eliminating entitlement risk. With all discretionary approvals secured and the development plan fully defined, 40th & C Street represents a turnkey opportunity for builders and investors to deliver a 29-unit residential community in a growing San Diego neighborhood.
