Property details
About 22427 Plummer St
Incredible development opportunity on one of the last remaining 2.6+ acre gated estates in Chatsworth. Full architectural plans and drawings are available to convert the existing "Carriage House" into a 2-bed, 2-bath, 1,200 sq ft ADU and add over 300 sq ft to the main home (permits from 2019 have expired). Whether you're looking to renovate, expand, or explore lot split potential (buyer to verify), this property offers unmatched flexibility. The main residence is ready for cosmetic updates, while the second structure—with its own address—presents an ideal rebuild opportunity. Designed by renowned architect Robert Byrd, the original home retains signature character and charm. Existing amenities include a lighted tennis/pickleball/basketball court, pool, three storage sheds, and a detached garage with a workshop. Nestled among mature oak trees, the grounds offer beauty, shade, and total privacy. Property profile designates use as a duplex. Endless potential for investors, builders, or end-users looking to create a custom compound or private estate.
