ADU Construction in Rancho Cordova

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 Rancho Cordova and across Sacramento County, and manages each project from the first site review to the final inspection under one contract.

ADUs we build in Rancho Cordova

• 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 Rancho Cordova

Rancho Cordova is a city along Highway 50 and the American River, with 1950s and 1960s neighborhoods north of the freeway and newer subdivisions to the south.

Most Rancho Cordova 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.

Many Rancho Cordova neighborhoods have an HOA. Under California law an HOA cannot prohibit an ADU, but it can apply reasonable standards for things like materials and appearance, so we review your CC&Rs and plan for architectural review alongside the building permit.

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^®

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 Rancho Cordova 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.
