About This Lot

As of November 2025

Price improvement: Now offered at $400,000, this 5,500 sq ft lot at 1003 E Mariposa St is set back from the street with easement access, offering privacy and a peaceful setting just minutes from the center of Altadena. The land has been fully cleared through certified Phase I and Phase II post-fire cleanup and is ready for new construction. Zoned LCR2YY, the property may allow for a single-family residence or potentially two units, such as a main home with an additional unit (buyer to verify with the county). The lot formerly hosted a 2-bedroom, 1-bath home of approximately 845 sq ft with a detached garage. All utilities were previously connected and are available at the street (buyer to verify availability and reconnection requirements). The lot is rectangular and privately situated beyond the street. Buyers and builders might be able to take advantage of L.A. County’s post-fire pre-approved plan and AI-assisted permitting program, enabling faster approvals and reduced design costs. Opportunities for new development in this area are limited, and the surrounding neighborhood has seen increased interest in redevelopment. Note: Any home rendering image shown is AI-generated for illustrative purposes only and may not reflect actual plans or buildable features. All information is deemed reliable but not guaranteed. Buyer to independently verify zoning, building regulations, and all aspects of property development with the appropriate local authorities.
