Frequently Asked Questions About ADU Construction
1. What is an ADU and how can it help my Los Angeles property?
2. Can Golden State Construction convert my existing garage or basement into an ADU?
Yes. We handle garage conversions, basement apartments, and other space conversions. We evaluate the existing structure, utilities, and zoning rules, then recommend the best approach and coordinate architectural plans.
3. How long does an ADU project take from planning to construction begins?
Timelines vary based on scope, permitting, and site conditions. Typical projects take 4–9 months from early planning through final inspection, with permitting often being the biggest variable. We provide schedule estimates as part of your proposal.
4. Do I need a building permit to build an ADU in Los Angeles?
Yes. A building permit and building permit application are required for most ADU projects. We assist with the entire permitting process, including fees and inspection coordination, to ensure your ADU meets local building codes.
5. What are the common ADU types you build?
We build detached ADUs, attached ADUs, garage conversions, basement apartments, carriage houses, and “granny flats.” We can also design accessible dwelling units on request.
6. How do zoning rules and local regulations affect my ADU?
7. Can an ADU generate rental income and how does it affect property taxes?
8. What financing options are available for building an ADU?
9. Will my ADU need separate utilities or can it share with the primary house?
Some ADUs share utilities with the main home, while others have separate utility connections or meters, depending on code requirements and project goals. We coordinate all utility connections and advise on metering.
10. What is included in Golden State Construction’s ADU services?
We provide site evaluation, ADU design coordination, architectural plan support, permit application assistance, full construction, on-site management, inspection coordination, and a 1-year workmanship warranty.
11. How much will my ADU construction costs be?
Costs depend on size, ADU type (detached vs conversion), finishes, and site conditions. We offer free estimates and a transparent cost breakdown during the proposal phase—no hidden fees or surprise change orders.
12. Do you follow California contractor laws and deposit limits?
Yes. We strictly follow California contractor laws, including deposit limitations and clearly defined payment milestones, to protect homeowners and keep the process fair.
