Boasting a sprawling lot of 171,283 square feet (per public records) with a sizeable vintage home that takes in the breathtaking mountain setting and views of the San Gabriel Mountains. Capture the RARE investment options/scenarios within this desirable location that features horse property with unmatched Development potential. Multiple ADU's or subdivision of the lot are to be fully investigated and verified by Buyer as to City/building requirements/restrictions. Prior consideration was for subdividing the lot in to possibly 16 different sites. If you appreciate a vintage era beauty then renovating the existing home, which is in need of makeover & repairs, could be considered. This was a cherished family property for decades. There are 2 separate gated entries to the property, an expansive front yard with mature trees including California Oaks throughout. A fenced in pool, not currently in use, is situated in front of the main house. Beyond the home to the rear of the property is spacious/generous level land. A structure used as guest house is just north of the house. Incredibly serene and private setting waiting to be reimagined and re-designed for best usage purposes. ## Location - **Address:** 819 N Walnut, San Dimas, CA 91773 - **County:** Los Angeles ## Listing Agent - **Name:** Patrick Wood · **License:** 00615225 - **Brokerage:** Help-U-Sell Prestige Properties - **Broker Phone:** 909-597-5252 ## Photos ![819 N Walnut - Photo 1](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f3816970371r.jpg) ![819 N Walnut - Photo 2](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f768227295r.jpg) ![819 N Walnut - Photo 3](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1602683216r.jpg) ![819 N Walnut - Photo 4](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f3393079600r.jpg) ![819 N Walnut - Photo 5](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2704992448r.jpg) ![819 N Walnut - Photo 6](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1581257521r.jpg) ![819 N Walnut - Photo 7](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f3922218939r.jpg) ![819 N Walnut - Photo 8](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2024178335r.jpg) ![819 N Walnut - Photo 9](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1083571978r.jpg) ![819 N Walnut - Photo 10](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f3008323800r.jpg) ![819 N Walnut - Photo 11](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1646987530r.jpg) ![819 N Walnut - Photo 12](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f552083906r.jpg) ![819 N Walnut - Photo 13](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2169409411r.jpg) ![819 N Walnut - Photo 14](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2398419215r.jpg) ![819 N Walnut - Photo 15](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f4022138253r.jpg) ![819 N Walnut - Photo 16](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1671566385r.jpg) ![819 N Walnut - Photo 17](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1634590308r.jpg) ![819 N Walnut - Photo 18](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1126582206r.jpg) ![819 N Walnut - Photo 19](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1551943003r.jpg) ![819 N Walnut - Photo 20](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f3048015323r.jpg) ![819 N Walnut - Photo 21](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f140009903r.jpg) ![819 N Walnut - Photo 22](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1740209595r.jpg) ![819 N Walnut - Photo 23](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2938135643r.jpg) ![819 N Walnut - Photo 24](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2739305814r.jpg) ![819 N Walnut - Photo 25](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f3547512426r.jpg) ![819 N Walnut - Photo 26](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f3391967573r.jpg) ![819 N Walnut - Photo 27](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2982637774r.jpg) ![819 N Walnut - Photo 28](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2462866935r.jpg) ![819 N Walnut - Photo 29](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f720867005r.jpg) ![819 N Walnut - Photo 30](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2956200680r.jpg) ![819 N Walnut - Photo 31](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f1303978223r.jpg) ![819 N Walnut - Photo 32](http://lh.rdcpix.com/df0f0dfa0815cd70a79703fd421e1d9cl-f2114366029r.jpg) --- **MLS#:** CV26240998 | **Updated:** 2026-11-14 **Source:** listhub *Copyright © 2026 California Regional Multiple Listing Service, Inc.
