TL;DR. Buildability™ checks whether a San Diego lot can support new construction, a teardown-rebuild, an addition, or an ADU — all in one pass. Zoning, FAR, lot coverage, setbacks, height limits, and overlays, layered against California state law. Free for your first address.
What's typically possible on a San Diego lot
Most San Diego lots fall under a residential zone that permits one or more of: a new single-family home, an addition, an ADU, a detached garage, or a teardown-rebuild. What's actually feasible depends on lot size, existing structures, setbacks, FAR, height limits, and overlays like historic districts, flood zones, or hillside/slope rules. With a median home value around $900K in San Diego, adding buildable square footage or a new unit can meaningfully shift property value. Buildability™ reads your specific parcel against San Diego's code — not a neighborhood generalization.
The hidden blockers to check first
Builders in San Diego routinely spend $3,000–$8,000 on preliminary design before learning their project is blocked by an easement, overlay, or setback encroachment they didn't check first. Buildability™ catches those blockers before you spend soft costs.
