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.

Frequently asked in San Jose

What are the disadvantages of ADUs?

Disadvantages can include the initial cost of construction and potential impacts on your current yard space. You'll also need to consider any new utility hookups required. However, for many San Jose homeowners, the benefits of increased property value and rental income outweigh these concerns. It’s worth getting a personalized quote to see how it fits your situation.

How much does an ADU cost in California?

The cost for an ADU in California, including San Jose, really depends on the size, materials, and site preparation needed. Factors like foundation type, if you're going for a detached unit, or a complex foundation can significantly affect pricing. We can give you a much clearer picture once we understand the specifics of your property and desired ADU type during your free consultation.

What are the rules for ADUs in California?

California has state-level laws encouraging ADUs, but local jurisdictions like San Jose also have specific zoning ordinances. These cover things like maximum unit size, height limits, and parking requirements. Understanding these local rules is crucial for a smooth process. We can help you figure out what applies to your specific San Jose location.

What are the rules for ADUs in California?
