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.
An accessory dwelling unit is a secondary, self-contained living area located on the same lot as a primary residence. It includes its own kitchen, bathroom, and sleeping area. You might hear these referred to as granny flats, carriage houses, or backyard cottages. You need to know this term when researching your local zoning codes, as it is the official legal definition used by building departments to regulate your project.

Accessory dwelling unit (ADU) construction in San Jose begins with site evaluation and design, followed by obtaining necessary permits from the City of San Jose.

Prefabricated accessory dwelling units (ADUs) in San Jose offer potential advantages like faster construction timelines and often more predictable costs, as many components are built off-site in controlled factory conditions.
