Types of ADU Projects They Handle
Stand-Alone (Detached) ADUs
Gary Faith Construction builds detached ADU units that function as fully independent living spaces on a property. These standalone units can serve a range of purposes — housing family members, providing rental income, or functioning as a dedicated home office or guest space. Their team manages the design and construction process while ensuring compliance with local regulations.
Above-Garage ADUs
For properties where yard space is limited, an above-garage ADU can be a practical option. Gary Faith Construction has experience building living spaces above existing garages, creating functional units that can be used for guests, tenants, or as a home office. They offer a free consultation to assess whether a property's existing garage structure is suitable for this type of addition.
Garage Conversion Contractor Services
Garage conversions are one of Gary Faith Construction's core specialties. They have completed numerous projects transforming existing garage spaces into livable accessory dwelling units. Their team manages every phase of the conversion — from design and permitting through to final construction. Past garage conversion projects have included features such as living rooms, full bathrooms, kitchenettes, and laundry facilities.
Notable completed projects include:
- Canata ADU — A garage conversion that was redesigned to include a living room, bathroom, and laundry area.
- Granada ADU — A new second floor built above a garage to increase usable space on the property.
- Meade Ave. ADU — The existing garage was demolished and rebuilt, with a laundry room on the ground level and a living space with a full bathroom and kitchenette on the upper floor.
Their ADU Building Process follows a structured five-step approach:
- Consultation — A free initial meeting to assess scope, preferences, and budget.
- Estimate — A detailed written estimate covering project elements and costs.
- Project Plan — Coordination with designers to develop plans and establish timelines.
- Construction — Active building phase with regular progress communication.
- Completion — A final walkthrough to confirm the project meets expectations.
San Diego County ADU Regulations
San Diego County permits homeowners to build one ADU and one Junior ADU (JADU) on single-family residential lots. For multifamily properties, up to two detached ADUs may be allowed. Detached ADUs can be up to 1,200 square feet, while attached ADUs are limited to 50% of the primary dwelling's square footage or 1,200 square feet — whichever is less.
Homeowners in San Diego are permitted to act as owner-builders for ADU projects, though all local zoning laws, building codes, and permitting requirements still apply. This includes obtaining proper permits before construction begins, meeting setback and height requirements, and passing city inspections at various stages. Many homeowners opt to work with a licensed ADU contractor like Gary Faith Construction to manage compliance and reduce the risk of costly errors.
Gary Faith Construction is licensed and insured, and their team is available to answer questions about granny flat builds, garage conversions, above-garage units, and other ADU-related projects. They offer free consultations for homeowners considering an ADU on their San Diego property.
