ADU Construction in West Sacramento

An accessory dwelling unit (ADU) adds a complete, permitted living space on the lot you already own: room for aging parents or grown kids, a home office, or rental income that helps cover the mortgage. TDI^® builds ADUs in West Sacramento and across Yolo County, and manages each project from the first site review to the final inspection under one contract.

ADUs we build in West Sacramento

• Detached ADUs, a standalone backyard cottage with its own foundation, kitchen, bathroom and entrance
• Attached ADUs, a new unit built onto the existing home with its own entrance
• Garage conversions, turning an attached or detached garage into a full living unit
• Junior ADUs, up to 500 square feet carved out of existing space inside the home, with an efficiency kitchen and a separate entrance
• Above-garage units, where the lot and local rules allow it

Building an ADU in West Sacramento

West Sacramento is a Yolo County city across the river from downtown Sacramento, with older neighborhoods, riverfront development and newer subdivisions in Southport.

On smaller and urban lots in West Sacramento, setbacks, access and utility connections shape what fits. Garage conversions and junior ADUs are often the most practical options, and California law allows reduced setbacks for ADUs, which can make a compact backyard unit possible where a larger structure would not fit.

Newer homes usually have more electrical and plumbing capacity to work with, which can simplify the utility connections for a new unit. We still verify the panel size and the sewer and water connections before design is final.

Being close to the river and the Delta means damp winters, tule fog and higher humidity than towns farther from the water. We design ADUs to California Title 24 energy standards, with insulation, window placement and a properly sized heating and cooling system so the unit stays comfortable year round.

How an ADU project works with TDI^®

1. Site and zoning review. We look at your lot, setbacks, utilities and access before anything is drawn, so the design fits what can be permitted.
2. Design and drawings. We coordinate floor plans and construction drawings sized to your goals and budget.
3. Permits and plan check. We submit the application to the City of West Sacramento building division, answer plan check comments and track the permit through approval.
4. Construction. Foundation, framing, roofing, plumbing, electrical and HVAC, insulation to Title 24, then drywall, cabinets, fixtures, flooring and finishes.
5. Final inspection and walkthrough. We close the permit and walk the finished unit with you, so you have a legal, insurable, rentable space.
