Property Description
32,500 SF | Up to ~18 Units | CR Zoning Located at the end of a private, secluded dead-end street lined with newer construction, this site is anchored by a remodeled 5-bed, 3-bath, 2,780 SF home producing rental income from day one. Zoned Community Residential (CR), it subdivides at 5,000 SF minimum lot sqf, with density that scales by lot size to roughly 18 units across the site. Flexible zoning lets you build the mix the market wants: single-family, duplexes, triplexes, fourplexes, townhomes, stacked flats, cottage housing, and ADUs/DADUs. (Buyer to verify.) Hold the existing home for income while you entitle, then keep it on its own lot or redevelop to full density. Topography survey and geo-tech report already completed. Site previously had 3 houses and a detached garage; one house remains, but utility connections to the removed structures are still on site. Developer-friendly terms. Ideal for developers, investors, non-profits, or anyone building a private multi-generational compound.
