ADU Construction Services by S.D White Construction Inc
S.D White Construction Inc is a family-owned, licensed, and insured construction company based in Richmond, CA, with over 20 years of experience building across the Bay Area. They specialize in accessory dwelling unit construction, handling everything from initial design and permit applications through to final inspection and handover.
Their work covers a range of ADU types, making them a practical choice for Bay Area homeowners looking to add living space for family members or generate rental income on their existing property.
Types of ADUs S.D White Construction Inc Builds
- Detached ADUs (Backyard Cottages): Stand-alone structures separated from the main residence, offering independent living space with privacy for occupants.
- Attached ADUs: Additions connected directly to the primary home, suitable for keeping family members nearby while maintaining separate entrances and living areas.
- Garage Conversion ADUs: Existing garages, storage rooms, basements, or attic spaces converted into fully functional living units, avoiding the cost of new construction.
- Above-Garage ADUs: Units constructed on top of existing or newly built garages, making use of vertical space on the property.
As an experienced ADU contractor and accessory dwelling unit builder, S.D White Construction Inc manages the full scope of each project under one team. This includes design, permit handling, framing, electrical, plumbing, and final city inspection — without the need for homeowners to coordinate multiple subcontractors.
What to Expect During the Construction Process
S.D White Construction Inc follows a structured four-step process designed to keep projects on track and homeowners informed throughout.
- Free Consultation and Site Assessment: The team visits the property, discusses the homeowner's goals — whether that's housing for aging parents, adult children, or rental income — and provides honest answers about design options, permits, timeline, and budget.
- Design and Permit Handling: A custom ADU design is developed to suit the property and the homeowner's needs. S.D White Construction Inc submits all permit applications to the city and coordinates with inspectors, handling the regulatory process on the client's behalf.
- Construction and Regular Updates: Their licensed crew carries out the build from foundation to finish. Homeowners receive regular progress updates so they remain informed at each stage of construction.
- Final Inspection and Handover: The team coordinates the final city inspection to confirm the completed unit meets all applicable building codes before handing over the finished ADU.
Most projects are completed within 3 to 5 months. S.D White Construction Inc places emphasis on sticking to agreed timelines, which allows homeowners to plan ahead — whether that means arranging for a family member to move in or preparing a rental unit for tenants.
Practical Benefits of Building an ADU
For Bay Area homeowners, an accessory dwelling unit can serve several practical purposes:
- Housing for family: ADUs allow extended family members — including aging parents or adult children — to live on the same property while maintaining separate, independent living spaces.
- Rental income: A detached ADU, granny flat, or backyard cottage can be rented to long-term tenants or short-term guests, providing an additional income stream.
- Cost-effective construction: ADUs do not require purchasing new land or building shared infrastructure, making them a more affordable housing option compared to new multifamily developments in California.
- Wood frame construction: S.D White Construction Inc uses wood frame building methods, which are proven and cost less than alternative construction approaches while delivering comparable quality.
S.D White Construction Inc serves Richmond and the broader Bay Area as a full-service ADU builder. Their approach is built around clear communication, defined timelines, and managing the entire project from a single point of contact — from the first site visit through to the day the keys are handed over.
