ADU Property Clarity Report — sample report cover
The Expensive Wrong Turn

The Red Flags Most Homeowners Find Too Late

Most ADU projects get expensive before construction starts.

That usually happens when early decisions are made around assumptions instead of the actual property.

One missed size, placement, parking, utility, or setback issue can force the plan to change after money is already in motion.

A plan built on the wrong assumptions can send the entire project in the wrong direction.

What Gets Expensive

ADU Projects Can Quietly Lose $5,000 to $50,000 Before Construction Ever Starts

Most ADU costs do not appear all at once.
They build one unverified assumption at a time.
1
Your ADU Comes Back Smaller Than Expected

When the property cannot accommodate the size you planned around, more than the footprint may change. The layout, bedroom count, rental potential, and overall project value may all need to be reconsidered.

Potential Cost Exposure:
$2,500–$10,000+
2
The Layout Has to Be Redrawn

A placement that looks right on paper may conflict with setbacks, access, privacy, windows, utilities, fire requirements, or usable yard space. When those conflicts appear after design begins, the plans may need substantial revision.

Potential Cost Exposure:
$3,000–$15,000+
3
Utilities Change the Entire Budget

The route to sewer, water, gas, and electrical service can materially change the scope of the project. A longer or more difficult connection may mean trenching, rerouting, panel work, service changes, or additional investigation.

Potential Cost Exposure:
$10,000–$40,000+
4
Every Delay Pushes the Outcome Further Away

Time spent in redesign, permit corrections, and unanswered property questions is time the ADU is not producing rent, housing family, or delivering the financial result you planned for.

Potential Delay Cost:
$2,000–$4,000+ per month

Question the assumptions while the project is still flexible.

It all comes in a 10-page property report with your findings laid out page by page — yours to keep, print, and put in front of any contractor or architect you ever talk to. When someone quotes your project, you’ll be the homeowner holding the answers, not the one hoping they’re right.

The Best Outcome Is Knowing What You’re Working With

When the early findings are encouraging, your Clarity Report helps you understand what your property may support, where an ADU could potentially fit, and which direction appears worth exploring.

If the review uncovers a potential concern, you discover it while the project is still flexible enough to adjust the direction.

Either result puts you ahead: a clearer path forward—or an early warning before the expensive decisions begin.

The homeowners who move forward with the most confidence are the ones who understand their property, their constraints, and the questions that still need answers.

What Changed Once Homeowners Had the Facts

“”

I thought I could build an 800 sq. ft. two-bedroom ADU, but the report showed my usable area was tighter than I expected. It helped me plan around a smaller one-bedroom instead and gave me a more realistic budget.

I assumed I could place the ADU close to the back fence, but the report showed the fire-code setback could push it farther into the yard than I pictured. That helped me rethink the size and placement instead of designing around the wrong spot.

Before ordering the report, we weren’t sure if our lot would work for an ADU or where the unit could actually fit. The report gave us a clear answer, showed us the likely placement, and helped us move into permitting with a lot more confidence.

Why the Order Matters

The Property Comes
Before the Plans

ADUPlanner
California — 2026

You didn’t start thinking about an ADU by accident.

Maybe it’s rental income that gives your household more breathing room. Maybe it’s a place for your parents to live close by while still having a space of their own. Or maybe you already have a picture in your head of what belongs in the backyard.

The idea is usually the easy part.

What makes ADU projects difficult is figuring out how that idea fits the actual property.

After years of working around California construction and ADU projects, one lesson keeps coming up: the order matters.

Homeowners often start with a floor plan, a prefab model, or a contractor estimate before anyone has taken a close look at the property itself.

Then the real questions start showing up.

Where can the ADU realistically sit?
What setbacks or access requirements matter?
How will utilities reach it?
Is there something on the property that could change the direction of the project?
What still needs to be confirmed before design begins?

Those questions are exactly why we created the ADU Clarity Report.

We start with your property and the rules that may apply to it. We look at the likely ADU path, placement, size, utilities, access, red flags, and the assumptions that still need verification.

The goal is not to design your ADU for you or sell you construction.

The goal is to give you a clearer picture of the property before you enter those conversations.

Our process is informed by real-world construction experience, and when a project moves into an on-site review, visible site conditions and findings can be reviewed with licensed California contractor oversight where appropriate.

That practical perspective matters because a property can look simple online and tell a very different story once someone understands what to look for in the field.

The Clarity Report puts that information in one place so you can move forward with better questions, clearer expectations, and a stronger understanding of your options.

You should be able to sit down with a designer, contractor, architect, or builder and understand the direction of your own project — rather than depending entirely on the person trying to sell you the next service.

That is what ADUPlanner is here to provide.

Clarity before design. Direction before the next decision.

The property is yours.

Let’s find out what it may support.

Questions Homeowners Ask Before Moving Forward

Why should I do this before talking to a designer or contractor?

Because you should understand the property before someone designs around assumptions. The report helps you identify the lot constraints, likely ADU direction, and questions that still need confirmation so those conversations start from better information.

What do I receive?

A 10-page, property-specific PDF report reviewing your parcel against your city’s rules and state ADU law — eligibility, size and placement, setbacks and constraints, utilities, fees, and your safer next step — plus a 15-minute expert review call to walk through it. Yours to keep, print, and put in front of any contractor or architect you talk to.

What do you need from me?

About 10 minutes. After checkout you complete a short intake form — your property address and what you’re hoping to build. We handle the rest.

How fast do I get the report?

Within 48 hours of your completed intake — or the report is free.

What is the difference between the $195 and $495 options?

The $195 Clarity Report is a 48-hour review of your parcel, your city’s rules, and state ADU law. The $495 option adds an in-person site walkthrough by a licensed CA contractor team — red flags caught on the ground, on-site photos and notes, and a next-step roadmap. Most homeowners start with the $195 report.

Can’t the city tell me this for free?

The city can tell you what code theoretically allows — generic to your zoning. Your report tells you what’s actually buildable on your specific lot: your address, your site conditions, your utility situation, and the constraints that reshape projects. That’s the difference between a rule and an answer.

What if the report says I can’t build what I want?

Then the report still did its job. You learned what appears to stand in the way, what may be adjustable, and whether the smarter next step is to move forward, modify the idea, or pause.

What is your refund policy?

Your report is delivered within 48 hours of your completed intake — or it’s free. Full details are in our Refund Policy, linked in the footer.
