309 Grace Ave is a 6,560 sq ft single-family residential lot in the heart of La Habra, Orange County. Built in 1961, the existing 1,600 sq ft structure carries only 10% of the total assessed value — making this a compelling land-value play for developers and investors. The property sits in a designated Transit Priority Area and Low VMT Generating Zone, enabling streamlined by-right ADU and SB 9 development approvals. With a 151-foot lot depth, the site is ideally configured for a detached ADU or a full SB 9 lot split into two parcels, each supporting primary dwelling plus ADU — for a maximum of 6 dwelling units.
