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.
ADU services simplify the complex process of turning unused yard space into a functional, independent living unit.

Engaging experts ensures the project stays compliant with state codes while meeting your specific design goals for a secondary dwelling.
Potential downsides include navigating San Jose's specific zoning ordinances and potential impacts on existing utility services. You'll also need to consider the upfront costs and construction timelines. However, the benefits of increased property value and rental income often outweigh these challenges for homeowners.
