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.

What are the rules for ADUs in California?

California has statewide standards that streamline ADU development, often with fewer restrictions than many other states. These rules focus on reducing barriers to construction. However, specific local San Antonio requirements still apply and need to be followed for compliance.

That grant is specific to California and not applicable in Texas. While there aren't similar statewide grants for ADUs in San Antonio, exploring local incentives or financing options is still a good idea. We can discuss potential avenues for funding your project.
