What is an ADU feasibility report, and do you need one?
Before you hire an architect, talk to a contractor, or spend a dollar on plans, there's one question you need to answer first: is an ADU actually feasible on your property?
What an ADU feasibility report covers
A feasibility report is a written assessment of your specific property. It looks at zoning, setbacks, lot coverage, ADU eligibility under California state law, and jurisdiction-specific requirements for your city, not just general state law.
Why it matters before you spend money on plans
Architectural plans for an ADU typically cost $8,000–$25,000. If your property has a setback issue, lot coverage constraint, or zoning restriction, you could spend that money on plans you can never use. A feasibility report surfaces those issues upfront.
Who needs one
You need a feasibility report if you're considering an ADU but haven't started design yet, you're buying a property and want to understand its ADU potential before closing, or you've received conflicting information from your architect or contractor about what's allowed.
