Building an ADU in Fair Oaks
Fair Oaks is an unincorporated community along the American River bluffs, with a historic village center, older homes and wooded, sloped lots.
Most Fair Oaks lots can fit at least one type of ADU. A detached unit works where the backyard has room, while a garage conversion reuses an existing structure and is often the fastest path to a permitted unit.
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.
Sacramento Valley summers are long and hot, and winter rain comes in concentrated storms. 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®
- 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.
- Design and drawings. We coordinate floor plans and construction drawings sized to your goals and budget.
- Permits and plan check. We submit the application to Sacramento County Building Permits and Inspection, answer plan check comments and track the permit through approval.
- Construction. Foundation, framing, roofing, plumbing, electrical and HVAC, insulation to Title 24, then drywall, cabinets, fixtures, flooring and finishes.
- Final inspection and walkthrough. We close the permit and walk the finished unit with you, so you have a legal, insurable, rentable space.
Licensed and accountable
- CSLB licensed general contractor, License #1041773, Class B General Building
- Native American owned (Cherokee) and a certified Minority Business Enterprise
