Request your free review
Takes about a minute. A real Southern California ADU advisor reviews every request.

Submitting isn't a financing, permit, or construction application — it starts a preliminary planning conversation. We never sell your information.

What your free review covers

Potential ADU configurations — detached, attached, garage conversion, or Junior ADU — and the possible scale for a lot like yours.
A preliminary cost range to plan around — a planning-level estimate, not a quote or appraisal.
Major property considerations — the things worth checking before you invest in design.
Local planning resources and contractor-readiness questions — plus the recommended next steps for your situation.

The review is intended for preliminary planning and does not replace professional design, engineering, permitting, appraisal, legal, or construction services.

How it works

1
We review your property information
Share the basics about your lot and goals. A real advisor reviews every request against what's realistic for a property like yours.
2
You get a straight answer
We follow up with possible options, a planning-level cost range, and anything worth checking — including an honest "not yet" if that's the real answer.
3
Contractor introductions — only with your separate say-so
Your information is not shared with contractors as part of the review. If you later decide you want introductions, we ask for your separate consent first, and only then may we connect you with up to three carefully selected local builders. You choose who — if anyone — to hire.

Why talk to UBP before choosing a contractor

A contractor you call directly is naturally selling their own services. UBP is a planning resource that comes first: we help you understand what may be possible, establish a realistic preliminary budget, and organize the project — so when proposals arrive, you can compare them clearly and ask better questions. Homeowners don't pay UBP directly. The intention is that participating contractors compensate us and set their own project pricing independently, but those arrangements remain under review and are subject to change.

Quick questions

You won't receive a UBP invoice for the preliminary review or contractor introductions. The intention is that participating contractors compensate UBP and determine their own project pricing, but those arrangements remain under review and are subject to change. Here's the current thinking on how the model works.

No. Your request goes to UBP first, not to a contractor list, and your information is not shared with contractors as part of the review. If you later decide you want introductions, we ask for your separate consent first — and only then may we introduce you to at most three participating contractors, not a dozen cold calls.

We'll tell you directly, with the reason. An honest "not yet" is part of the service — you'll know what's standing in the way and what to check next.

No. There's no obligation to hire anyone, and submitting isn't a financing application, permit application, or construction contract — it starts a preliminary planning conversation.

Southern California — Los Angeles County, Orange County, and the Inland Empire. We publish city-specific ADU guidance across the service area.
