Tentative Parcel Map 94-149 was approved at the Planning Commission level in 1994 and by City Council in 1995. County recordation is the remaining step. The entitlement work is done. Parcel 2 is the rear flag lot with the existing 3, 432 SF residence, 4 bedrooms, 3.5 baths, pool, two fireplaces, and a 2-car garage. Hold it, rent it, or redevelop. ADU rights are confirmed on both parcels simultaneously: a converted ADU, a JADU up to 500 SF, and a detached ADU up to 800 SF. Sewer lateral replaced 2024. Variance in place for the existing front fence. Buyer to verify with the city. Old Town Tustin continues to attract significant buyer and developer interest. Walkable to restaurants, retail, and the weekly farmers market.
