About this property
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-bedroom, 3-bath, 2,780 SF home generating rental income from day one. Zoned Community Residential (CR), the site subdivides at a 5,000 SF minimum, with density that scales by lot size up to roughly 18 units across the site. Flexible zoning allows you to build the mix the market wants: single-family, duplexes, triplexes, fourplexes, townhomes, stacked flats, cottage housing, and ADUs. (Buyer to verify.) Hold the existing home for income while you entitle, then keep it on its own lot or redevelop to full density. Utilities previously served three homes on-site. The mostly flat topography means less grading and lower site-work cost. Seller is open to developer-friendly terms. Ideal for developers, investors, non-profit or a family building a private multigenerational compound.
