What affects the price

Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.

About this service

A prefab ADU is a structure built off-site in a factory and then transported to your property. Since the components are manufactured in a controlled environment, these units often have shorter construction timelines than traditional builds. You might choose this if you want to minimize noise and debris in your backyard. Costs depend on the complexity of the design, the quality of materials, and the foundation work required.

Local planning departments review plans for compliance with zoning and building codes, so a thorough understanding of these specifics is vital before commencing any work.
