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 unit constructed off-site in a controlled factory environment before being delivered and assembled on your property. You might choose this option if you want a faster construction timeline and less disruption to your yard compared to traditional building methods. Once the foundation is ready, the structure is dropped into place and connected to utilities. It is an efficient way to add housing while maintaining high quality control standards throughout the entire manufacturing process.
