Prefab adu — Daly City, CA
Last updated: September 24, 2026
An accessory dwelling unit (ADU) is a secondary housing unit, like a backyard cottage or an in-law suite, on a single-family residential lot. These units in Daly City provide flexible living options, from housing family members to generating rental income. They are a smart way to increase your property's utility and value without subdividing the lot. In a densely populated area like Daly City, maximizing existing space is key. Many homeowners in neighborhoods like Westlake or Serramonte are exploring ADUs. They recognize the potential for added income and accommodating multi-generational living. They've worked on projects throughout the city, from the coastal areas to the inland districts. Their expertise ensures your ADU is compliant and well-constructed. This means a smoother process for you. Getting started is about understanding your property's potential. We make that easy. Call us today to explore your ADU options.
What affects the price
Building an ADU involves several moving parts that shape your total budget. The biggest factor is whether you choose a prefabricated unit or a custom build on-site. Site preparation is also significant; if your land requires extensive grading, utility trenching, or foundation work, costs will climb. Your choice of finishes—like kitchen cabinetry, flooring, and siding materials—also shifts the bottom line. We help you navigate these variables to find a setup that fits your property. Exact pricing confirmed free on the call.
About this service
A prefab ADU is built in a controlled factory environment and then transported to your property for final assembly. Because the units are constructed off-site, they often result in less noise and debris in your yard during the process. You need this if you want a more predictable timeline and efficient construction process. Exact pricing confirmed free on the call.
