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.

Have Plans or Need Them? Already have an architect? We come in as your General Contractor and manage the full build from your plans. Starting from scratch? We coordinate the architect, structural engineering and permits for you—one point of contact from concept to completion.

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 If you need plans, we coordinate architectural drawings and structural engineering. If you already have an architect, we build directly from your 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

  • From contract to Certificate of Occupancy, most projects take 6–12 months. Garage conversions typically move faster than ground-up builds due to permitting timelines.

  • Not necessarily. If you need plans, we coordinate the architect and structural engineer for you. If you already have an architect, you provide the plans and we build from them. We can recommend local architects we've worked with if needed.

  • Yes. We manage the full permit process including plan submission, coordination with the city, and all required inspections through final sign-off.

  • California state law limits HOAs from blocking most ADU projects. We'll confirm feasibility during the initial consultation.

  • A Junior ADU (JADU) is a unit of 500 sqft or less built within the existing home. A detached ADU is a separate structure. JADUs are typically faster and cheaper to permit and build.
