Frequently Asked Questions

Answers to your questions about ADUs and additions.

How much value does an ADU add to my property?
While market conditions vary, an ADU typically adds significant value—often 20-30% to your property value. Additionally, it offers the potential for monthly rental income, which can offset construction costs over time.
What are the setback requirements for a backyard ADU in Irvine?
Generally, detached ADUs require a setback of 4 feet from the side and rear property lines. However, rules can differ based on your specific zoning, lot size, and presence of easements. We perform a detailed feasibility study to confirm exact requirements for your lot.
How long does it take to build a room addition?
Room additions typically take 3 to 6 months to complete, depending on size and complexity. This includes framing, roofing, electrical, plumbing, and finishing. The permitting phase prior to construction can also take several weeks to a few months depending on the city's backlog.
