The Ellery ADU Studio Long Beach Guarantee
When you hire us for an ADU project in Long Beach, you’re not getting a handshake and a hope. You’re getting The Haven Standard in writing: a fixed price before any work starts, a documented photo record of every visit, and our 365-Day Done Right Promise. If the finished ADU doesn’t match the permitted drawings, we make it right. That’s not a slogan. It’s Clause 5, signed before the project begins. We’ve designed, permitted, and built over 900 ADUs since 2015, and every single one left with a written price and a photo trail. No exceptions.
What’s Covered
- Workmanship that matches the permit set. We build to the drawings that the City of Long Beach approved, not to what we think looks close enough. If there’s a deviation, we document it and fix it under our 365-Day Done Right Promise.
- Parts and material handling with full traceability. For prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, we specify the exact product, coordinate delivery, and verify condition on arrival. You get documentation of what was ordered and what showed up.
- Site cleanup that leaves no question about what happened. Our crews are background-checked and uniformed, and they leave the work area documented. The photo record shows the condition before we started and after we finished each phase.
- On-time project milestones tied to the written scope. We don’t promise impossible speed on construction. We do promise that every phase starts when the contract says it starts, with permit status and inspection scheduling tracked in real time.
- Honest pricing with zero scope creep. Under Haven Standard Clause 1, the price is written before work begins. Under Clause 5 (No Surprises), that scope locks at signing. No door-side upsells, no “we found something extra” pressure. The number you sign is the number you pay.
Our Satisfaction Promise
If something’s not right, we don’t debate whose fault it is. We fix it.
Here’s how that works in practice. During construction, you receive a documented photo record on every visit. That means you see what we found, not a summary of how it felt. If the slab is 4 inches and that’s within range for your garage conversion ADU, we tell you exactly that and show you the measurement. If a setback variance - the extra distance the city requires between your new ADU and the property line - affects your Belmont Heights lot differently than your neighbor’s in Bixby Knolls, we explain the variance and adjust the drawings before we build.
After completion, the 365-Day Done Right Promise is your backstop. If the finished ADU isn’t built to the permitted drawings, we return and make it right. No deductibles, no “normal wear and tear” exclusions, no runaround between designer and builder pointing fingers. Our one-contract design-build model means we’re the only phone number you call. Nadia Ellery answers, or a live person does, 24 hours a day. No voicemail queue, no callback that doesn’t materialize.
We’ve had homeowners in Long Beach call us six months after move-in because a door was sticking or a window wasn’t sealing the way the drawings specified. We showed up, pulled the permit set, compared it to what was built, and fixed what didn’t match. That’s the promise. It’s in writing before your project starts.
Before
AfterLicensed & Insured Backing
A warranty is only as good as the company that has to honor it. We’re licensed and insured, and our license number appears on every page of our site - verified, not just claimed. That matters in Long Beach, where the Building & Safety Bureau enforces the California Building Code plus local amendments for coastal zones, fire hazard areas, and historic districts. An unlicensed operator can disappear; a licensed contractor has a bond and a track record the city can audit.
Our insurance covers the property, the workers, and the project itself. If a subcontractor damages your existing sewer lateral during ADU site prep, our policy handles it. If a crew member is injured on your Signal Hill-adjacent hillside lot, you’re not exposed. The Haven Standard requires this coverage because a “guarantee” without financial backing is just a piece of paper. We’ve maintained continuous coverage since 2015, and we provide certificates on request.
We also carry the relationships that matter locally. Long Beach requires separate plumbing, electrical, and mechanical permits for most ADUs, plus a foundation inspection for detached units. We pull every permit, pass every inspection, and document every approval. Your final certificate of occupancy is real, recorded, and transferable when you sell.
Free Second Opinion: A Different Kind of Guarantee
We’re confident enough in our pricing and process that we’ll review any written estimate you already have. Bring us another contractor’s scope for your garage conversion in Alamitos Heights or a modular quote for a detached ADU in Los Altos. We’ll tell you what’s missing, what’s inflated, and what’s genuinely different. No charge, no obligation. If we’re not the right fit, we’ll say so. That’s been our practice since 2015, and it’s how we’ve earned the repeat referrals that built this studio.
What the Photo Record Proves
Every visit generates timestamped, geotagged documentation. You receive:
- Condition photos before demolition or construction begins
- Progress shots at rough framing, MEP (mechanical, electrical, plumbing), and final walkthrough
- Inspection results, including any corrections and re-inspections
- Final as-built documentation for your records
This isn’t for our portfolio. It’s evidence of what was found and what was done. When you sell your Long Beach home, that documentation answers buyer questions before they ask. When you need a repair in year three, we can pull the exact photo and know what we’re working with.
How Our Guarantee Differs from “Industry Standard”
Most ADU contractors offer a one-year warranty on workmanship. Some offer two. The problem isn’t the length; it’s the enforcement. Does the warranty cover only “defects in materials and workmanship,” which lets the builder blame the manufacturer? Does it require you to notify them in writing within 30 days of discovering the issue? Does it exclude “settling,” which in Long Beach’s clay-heavy soils can mean almost anything?
Our 365-Day Done Right Promise is simpler. Built to the permitted drawings. If not, we make it right. The drawings are the standard, not our interpretation of “industry practice.” And because we’re design-build, we control both the drawings and the construction. There’s no gap to hide in.
Call to Verify, Then Call to Start
We don’t ask you to trust us because we say we’re trustworthy. We ask you to verify: check our license, request our insurance certificate, call our references in Long Beach, ask about the Haven Standard. Then call (562) 414-4842 to schedule your free estimate. The price we write is the price you pay. The work we document is the work you get. And if it’s not done right, we make it right. That’s not a feeling. That’s the contract.
