Frequently Asked Questions
What is an ADU?
An ADU (accessory dwelling unit) is a secondary, self-contained living unit on the same lot as a home, such as a detached backyard unit, an attached addition, or a garage conversion. ADUs are popular in San Diego for rental income and multigenerational living. AH Construction designs and builds ADUs throughout San Diego County.
Do I need permits to build an ADU in San Diego?
Yes, ADUs in San Diego require permits, and they must comply with California’s state ADU laws as well as local zoning and building codes. The good news is that state law has streamlined much of the approval process. AH Construction handles permit planning and coordination as part of the project.
How much does it cost to build an ADU in San Diego?
ADU costs in San Diego vary based on size, whether it’s detached or a garage conversion, finishes, and site conditions, so there is no single price. Garage conversions are typically less than detached new-build units. AH Construction provides a free estimate and conceptual floor plans for your property.
Can you convert a garage into an ADU?
Yes, converting an existing garage into an ADU is one of the most cost-effective ways to add a living unit, since it reuses the existing structure. It still requires permits and code-compliant systems. AH Construction handles garage-to-ADU conversions across San Diego County.
How long does it take to build an ADU?
An ADU in San Diego typically takes several months from design through completion, depending on the type, permitting, and site conditions. A clear pre-construction and permit plan keeps it on track. AH Construction manages the full design-build process.
