ADU Construction in Temecula, CA
Full Permitting & Turnkey Construction
On time, on quote, and your home left cleaner than we found it.
An ADU gives aging parents a home of their own on your lot, or gives you a longer-term rental. The hard part is the rules: Temecula's ADU standards, the permit path and the utility connections. BMO Build Co. handles the design, the permits, the hookups and the build as one licensed general contractor (CSLB #1064672).
What rules apply to an ADU in Temecula?
Temecula sets its ADU and JADU standards in Municipal Code Chapter 17.23 and Section 17.06.070: size, setbacks, height and the number of units per lot. Before design starts, we check your lot against those standards so the plans go to the city ready for review.
2026 Build Types & Estimated Investment
- JADUs ($50k–$100k): Built inside your existing home, such as a converted bedroom, with its own cooking facilities.
- Garage Conversions ($100k–$175k): Repurposing an existing structure saves significantly on foundation and framing costs.
- Detached Units ($200k–$400k+): Standalone backyard homes with the most privacy, for family or a longer-term rental.
ADU Options for Temecula Homes
Detached ADU
A separate small home on the same lot as your house, with its own kitchen, bathroom and entrance. The most private option for a family member or a long-term tenant.
Attached ADU
Built onto your existing house, with its own entrance, kitchen and bathroom. A good fit when your yard has less open space.
Junior ADU (JADU)
Created by converting part of your existing home, such as a bedroom, into a smaller unit with its own cooking facilities.
Garage Conversion ADU
Turn an existing garage into a permitted living space.
