ADU Services We Offer in San Diego
Garage Conversions The most cost-effective ADU option. We convert your existing garage into a fully permitted, code-compliant living space — including framing, electrical, plumbing, insulation, and all interior finishes.
Detached ADU — Ground-Up Construction A standalone structure built from the ground up on your property. Ideal for maximizing rental income or creating a fully private living space. We handle design, engineering, permits, and construction.
Design-Build or GC-Only Already have an architect? We can come in as your General Contractor and manage the full build. Prefer a single point of contact from concept to completion? We offer full design-build services.

How It Works
1. Consultation & Feasibility We review your property, discuss your goals, and confirm what's buildable under current San Diego zoning and state ADU laws.
2. Design & Engineering For design-build projects, we coordinate architectural plans and structural engineering. For GC-only, we work directly from your architect's plans.
3. Permits We handle all permit submissions and coordinate with the City of San Diego or your local municipality. Current review times are 4–8 weeks depending on jurisdiction.
4. Construction Full project management from demo through final finishes. One point of contact throughout. Clean, professional execution.
5. Final Inspection & Certificate of Occupancy We see it through to the final sign-off so your ADU is legal, rentable, and move-in ready.
The Case for Building an ADU
San Diego is one of the most ADU-friendly cities in California. Recent state laws have made it easier and more affordable than ever to add a unit to your property.
Rental income potential: Most San Diego ADUs rent for $1,800–$2,800/month depending on size and location
Property value increase: Homes with ADUs sell for significantly more on average
No owner-occupancy requirement: For ADUs permitted after January 1, 2025, you can rent both your main home and the ADU
Impact fee waivers: ADUs under 750 sqft are exempt from development impact fees under SB 13 — saving $8,000–$15,000
Frequently Asked Questions
