Discover a comprehensive guide to San Diego ADU regulations. Learn how to navigate local laws, benefits, costs, and building tips for your granny flat.
San Diego’s ADU market has changed significantly since California’s accessory dwelling unit legislation took effect. Permit timelines are shorter, setback requirements have loosened, and more property configurations qualify than most homeowners realize.
Murray Lampert has been building in-law suites and accessory living spaces in San Diego since well before ADUs became a mainstream conversation. We understand what the City of San Diego and surrounding jurisdictions actually require — the specific permit pathways, utility connection standards, and design constraints that apply to your property.
An ADU project begins with a site assessment. Lot coverage, setbacks, existing utility connections, and the condition of the primary structure all affect what’s possible and what it costs. Murray Lampert’s architectural designers evaluate these factors early in the process, before any design work is finalized, so that the project you design is the project that gets permitted and built.
Common configurations include detached backyard units, garage conversions, attached additions with separate entrances, and interior conversions of existing space. Each has a different cost profile, permitting pathway, and design considerations. Our ADU design-build program is built around multigenerational living: affordable units for family members downsizing, aging-in-place spaces for older relatives, and flexible rooms for short-term guests or multi-purpose use.
