Common questions. Straight answers.
Explore planning, permits, and quotes before discussing your project with an independent professional.
Cost and quotes
How much will my garage conversion cost?
The proposed use, condition of the garage, utility work, and finishes all affect the scope. Ask a professional for a written estimate based on your property, including allowances, fees, and exclusions.
How can I compare estimates?
Describe the same layout and finish expectations to each professional. Compare the work included, payment terms, agency fees, and how changes or unexpected conditions will be handled.
Are permit and design fees included?
They may be quoted separately. Ask who prepares the drawings, submits the application, pays agency fees, and responds to review comments before signing an agreement.
Choosing a conversion
Is a garage bedroom the same as an ADU?
A room that remains part of the main home and an independent dwelling have different purposes. Explain your intended use to your designer and the reviewing department before choosing a plan.
What is the difference between an ADU and a junior ADU?
The City of San Diego describes an ADU as a separate dwelling and a junior ADU as a smaller unit within a home or attached garage. The junior unit may share sanitation facilities. Ask your reviewing agency which path fits the property and proposed use.
Can a detached garage become an ADU?
The City of San Diego describes converted or detached ADUs among its options. Eligibility depends on the property and proposed work, so confirm the applicable requirements with the reviewing agency.
What happens to parking?
The proposed use changes how the garage can be used. Ask the reviewing department about current parking and driveway requirements for the address before finalizing plans.
Permits and process
Where do I start with a permit?
Confirm the agency responsible for your address, then describe the garage and the room or unit you want. The City of San Diego provides a garage conversion permit bulletin; County Building Services handles permits for unincorporated areas.
How long will the process take?
Timing depends on the application, the reviewing agency, and the project. Ask the department about its current process and the professional about a schedule for drawings, construction, and inspections.
Who prepares the plans and handles inspections?
Responsibilities depend on your agreement. Ask the professional who will prepare and submit documents, respond to comments, and arrange inspections. Keep the approved plans and results with your project records.
Can I begin work after applying?
An application is not an issued permit. Ask the reviewing agency what approvals are needed before work begins.
Working with a professional
Does Garage Conversion SD perform construction?
No. Garage Conversion SD is a referral service connecting homeowners with independent professionals. If you hire a professional, you contract with and pay that professional directly.
How do I check a contractor?
Ask for the business name and license number, then check the license and any applicable workers compensation information with the California Contractors State License Board. Ask the professional for insurance details and confirm coverage with the insurer.
Is a consultation free?
Garage Conversion SD does not promise a free consultation. Ask the individual professional about any consultation, design, or estimate fee before scheduling.
