Can you build an ADU on your property? Get the answer before you spend a dollar.
A property-specific ADU feasibility study for California homeowners. Zoning, costs, permit requirements, rental income potential — analyzed for your lot, your city, your project.
An ADU feasibility report is a property-specific analysis that evaluates whether your California lot qualifies for an accessory dwelling unit — and what type, size, and budget to expect. ADUscale cross-references dozens of data points from paid property intelligence APIs (Zoneomics, Regrid, ATTOM, and others) and county- and city-level databases to examine your actual zoning classification, setback requirements, lot coverage limits, utility connections, and local permit rules — giving you a data-backed answer before you commit to architectural plans or construction contracts.
Your lot is checked against these registries simultaneously. Where the sources disagree, we reconcile against the county record of authority — not a single feed.
15 pages of property-specific ADU analysis.
Eight self-contained sections, written for the homeowner who wants a verdict — not a brochure. Every section answers a question you'd otherwise spend weeks chasing.
Your ADU feasibility score
A single number that tells you how viable your ADU project is — scored out of 100, based on your lot, zoning, regulations, and financial potential. This is the answer to "can I build an ADU on my property?" — expressed as a clear, data-backed verdict.
Your property, decoded
Lot size, zoning classification, existing structure footprint, setback requirements — pulled from paid property data APIs (Regrid, ATTOM, Zoneomics) and cross-referenced with county and city databases. Whether you're in Los Angeles, San Diego, San Jose, or Sacramento — the analysis is specific to your city's rules, not generic statewide data.
Every ADU option on your lot, ranked
Detached ADU, attached ADU, garage conversion, Junior ADU (JADU) — we evaluate every type that fits your property and rank them by size, ROI potential, and practical trade-offs. If you're considering an ADU garage conversion, you'll see exactly how it compares to building new.
ADU cost breakdown for your property
Total project cost range (conservative to optimistic), broken down by construction, permits, design, and contingency. Plus: projected monthly ADU rental income, property value uplift, and payback period. The ADU cost calculator you've been looking for — except it's based on your actual lot, not California state averages.
California ADU permit requirements — checked for your property
Parking requirements, coastal permits, CEQA compliance, local jurisdiction rules, ADU setback requirements — each checked against your specific property using live regulatory data from Zoneomics and municipal zoning databases. You'll see exactly what stands between you and a building permit in your California city.
What could go wrong — before you find out the hard way
Risks categorized as low, medium, or high — so you know what to watch out for before you hire anyone. Easements, HOA restrictions, utility constraints, environmental flags, and title issues that could delay or block your ADU project.
What your neighbors already built
Real ADU permits issued near your address — with dates, descriptions, and locations. Proof that your neighborhood already supports ADU development. If ADUs are getting approved on your street, that's the strongest signal your project is viable.

This isn't a generic ADU calculator or a contractor's sales pitch.
Three reasons the $199 buys you something neither Google nor a "free consultation" can give you.
This ADU feasibility report is for California homeowners who…
- Own property in California and are considering building an ADU — detached, attached, garage conversion, or JADU.
- Want to know if they can build an ADU on their property before talking to contractors or architects.
- Need to understand ADU costs, permit requirements, and rental income potential for their specific city.
- Want an independent feasibility study — not a sales pitch disguised as a consultation.
Questions homeowners ask before paying $199.
Same questions you'd type into Google. Answered here so you don't have to.
14-day, no-questions money-back guarantee.
If the report doesn't give you a useful answer about your property, ask for a refund within 14 days and we return the full $199 — no questions, no forms, no phone call. We can stand behind that because the analysis either hands you a clear verdict on your lot, or it doesn't — and you shouldn't pay for the second case.
$199. One report. Complete clarity on your California ADU project.
Find out if you can build an ADU on your property — before you spend thousands on plans that might not get approved.
