365-Day Done Right Promise - if it's not done right, we make it right

The Haven Standard delivered by Ellery, a proud Haven company.

365-Day Written Promise

“900+ ADUs designed, permitted and built since 2015 - every one with a written price before we started, and a documented record when we left. Every ADU job is quoted in writing before it starts and leaves a documented record, under The Haven Standard.”

The Haven Standard, delivered by Ellery ADU Studio, a proud Haven company.

Our 90-Day Done Right Promise: if the work we did isn’t right, we come back and make it right - no argument, no second invoice.

Our response promise: A real person answers our phone 24 hours a day, 7 days a week - and we get an estimator to your property within two business days and put the written estimate in your hands within one business day of that visit.

What Our Promise Actually Means

If your finished ADU is not built to the permitted drawings, Ellery ADU Studio makes it right – at no additional charge, with no forms to file and no case number to track.

Call (971) 497-2402

That sentence is the whole thing. The 365-Day Done Right Promise is not a goodwill gesture or a “we’ll see what we can do” call to customer service. It is a written commitment, signed before your project starts, that the finished structure will match the permitted set. If it doesn’t, the crew comes back. You don’t have to argue the point, escalate to a manager, or prove you deserve the fix. You tell us what’s wrong. We handle it.

Since 2015, every one of the 900+ ADUs designed, permitted, and built under The Haven Standard has carried this promise. The number that matters is not how long we have been in business. It is how many projects left a documented photo record behind them – evidence of what was found, what was built, and what you signed off on.

Why We Answer Fast, Everywhere

A one-crew shop can be excellent. But when that crew is booked, you wait – and waiting is where ADU projects fall apart.

Ellery ADU Studio operates with local crews across four states, coordinated under a single dispatch system that a single-market contractor cannot replicate. When you call (971) 497-2402, a real person picks up – not a voicemail queue, not a callback promise that may or may not materialize. That is Haven Standard, Clause 2, and it applies at 11 p.m. on a Tuesday the same as it does on a Wednesday morning.

The response window we commit to is specific: an estimator reaches your property within two business days of your call, and the written estimate is in your hands within one business day of that visit. We can keep that window honest because we have built the infrastructure to keep it – local crews, a real dispatch operation, and a documentation system that does not depend on any one person remembering to follow up. National reach. Local crew. One standard.

How We Make It Right

You Tell Us

Call (971) 497-2402 and describe what you’re seeing. No online portal, no ticket system, no waiting for an email thread to resolve. A live person takes the information and opens the file. If you have the project documentation we left you – and every Ellery project leaves one – have it handy, but it is not a requirement.

We Come Back Out

We schedule a return visit and send the same kind of crew that did the original work – background-checked, uniformed, and carrying the permitted drawings. They walk the discrepancy, not your description of it. There is no charge for this visit and no assessment fee.

We Fix It

If the work does not match the permitted set, we bring it into compliance. The fix is scoped in writing before anyone picks up a tool – Haven Standard, Clause 1 applies to corrective work the same as it applies to new work. No verbal agreements, no “we’ll sort it out as we go.”

You Sign Off

When the correction is complete, you receive an updated photo record documenting what was done. You confirm the work matches the drawings. That sign-off closes the item. If it doesn’t close cleanly, we do not consider it closed – that is what the 365-Day Done Right Promise means in practice.

What Stands Behind the Promise

The promise is only as good as the people and systems behind it, so here is what is actually present on every Ellery project.

Every crew member is background-checked and uniformed. Their license number appears on every page of this site – verified, not just claimed. Every project is quoted with a written price before work starts, per Haven Standard, Clause 1. There are no hourly rates, no subscriptions, no membership tiers, nothing to sign up for. Every job is priced job-by-job off a free written estimate, and that number does not change once work begins.

The design, the permit set, and the build travel under one contract – which means neither the designer nor the builder can point at the other when something is off. Both answers belong to the same document. The documented photo record is not a summary; it is evidence. And the 365-Day Done Right Promise is not a policy on a website. It is a written commitment, co-signed by Ellery ADU Studio and backed by The Haven Standard, before your project starts.

If you have a written estimate from another contractor and want a second opinion, that is also free. Call us, bring the document, and we will review it with you.
