Positioned directly below the upper parcel, Lot 449-102-18 encompasses approximately 4,438 square feet and shares the same development advantages: no hillside designation, no environmental sensitivity, and no special slope restrictions under the City of San Diego Development Regulations. The gentle descent across the site creates an opportunity for stepped or terraced development, providing natural separation between access and living areas while maintaining privacy and maximizing design potential. A retaining wall will be integrated into the building design, though only standard grading is required, ensuring efficient construction and simplified permitting. This lower lot is ideal for residential, mixed-use, or live/work concepts, particularly those that benefit from multi-level design and the property's natural topography. Like its neighboring parcel, this site benefits from the City's modernized parking standards, enabling developers to pursue reduced parking ratios or parking waivers in favor of maximizing livable or commercial space. Overall, APN 449-102-18 represents a flexible, regulation-friendly infill opportunity-simple to develop, cost-effective to build, and well-suited for creative urban design.
