The Ellery ADU Studio Glendale Guarantee
We stand behind every ADU we design, permit, and build in Glendale with one simple standard: if it’s not done right, we make it right. That’s not a slogan we printed on a truck. It’s the 365-Day Done Right Promise, and we put it in writing before your project starts. Since 2015, we’ve delivered 900+ ADUs across Los Angeles County, and every single one left with a written price agreed to upfront and a documented photo record showing what we found and what we fixed. In Glendale, where hillside grading rules and fire-zone setbacks can derail a project mid-stream, that paper trail matters. We don’t disappear after final inspection. We answer the phone when you call.
What’s Covered
- Workmanship guarantee. Our crews are background-checked, uniformed, and supervised, and the work they perform is covered by our 365-Day Done Right Promise. If the finished ADU doesn’t match the permitted drawings, we come back and correct it at our expense.
- Parts and material handling. We specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie. Every material order is documented in your written scope, and substitutions require your signed approval. No bait-and-switch on what arrives at your Glendale property.
- Site cleanup and protection. Your main house, driveway, and landscaping aren’t collateral damage. We protect what stays and leave the site broom-clean after every phase. The photo record shows the condition before we start and after we finish each stage.
- On-time milestone delivery. ADU timelines in Glendale depend on city plan check queues and LADWP service releases, which we don’t control. What we do control is our internal schedule, and we commit to those dates in writing. If our crew misses a milestone we set, we address the delay and the cost impact transparently.
- Honest, upfront pricing. Under Haven Standard Clause 1, every project is quoted with a written price before any work begins. The words “call for a quote” do not appear anywhere in our process. Your line-item estimate includes permit fees, utility connections, and contingency language so you understand what drives cost before you sign.
Our Satisfaction Promise
If something’s not right, here’s what happens. You call (424) 325-4322 and a live person answers, 24 hours a day. No voicemail queue, no callback that never comes. You describe the issue. We review the photo record from your project to verify what was documented versus what you’re seeing. If the work falls short of the permitted drawings or the written scope we agreed to, we schedule the correction and we cover the labor and materials to fix it. That’s the 365-Day Done Right Promise, and it’s in your contract before the first shovel hits the ground in Glendale.
We’ve had to honor it. In a 2022 garage conversion near Adams Hill, the final electrical panel location shifted six inches during framing to accommodate a discovered sewer line. The homeowner caught the discrepancy during walkthrough. We opened the wall, relocated the panel to the permitted location, repaired the drywall, and repainted. No change order, no argument. The fix cost us $1,400 and two days. The homeowner is now referring their neighbor. That’s how we want every project to end.
We don’t consider the job complete when the certificate of occupancy posts. We consider it complete when you’re satisfied that what was built matches what was promised. If you have a written estimate from another ADU contractor in Glendale, we’ll give you a Free Second Opinion and tell you exactly where their scope is clear, where it’s vague, and where the risk of a surprise cost lives.
Licensed & Insured Backing
Every page of our site carries our license number, verified, not just claimed. That license is the state’s minimum threshold, but for us it’s the floor, not the ceiling. We’re insured and bonded, which means if something goes seriously wrong, there’s a financial backstop that doesn’t depend on our goodwill. For a Glendale homeowner investing $150,000 or more in a detached ADU or $80,000-$140,000 in a garage conversion, that matters more than any sales pitch.
Licensing also means we pull permits and pass inspections. In Glendale, that includes plan check through the city’s Building & Safety Division, fire department review for hillside zones, and utility coordination with LADWP for separate meters. Unpermitted work doesn’t just risk fines. It kills resale value and can void your homeowner’s insurance. Our license, insurance, and bond are the infrastructure that lets us offer the 365-Day Done Right Promise with confidence. We don’t ask you to trust a handshake. We ask you to read the contract, verify the license, and call (424) 325-4322 when you want proof that someone’s actually there.
How the Haven Standard Protects Your Investment
Every Ellery ADU Studio Glendale project runs under The Haven Standard, a set of written clauses that govern how we work. Here’s what that means in practice.
Clause 1: Written Price Before Work Starts. Your estimate is line-itemed and fixed before signing. No verbal allowances, no “we’ll figure it out in the field.” In Glendale’s competitive ADU market, some competitors lead with a low number and add scope later. We don’t. The price you sign is the price you pay, unless you request a change and sign a change order.
Clause 5: No Surprises. The scope locks at contract. No door-side upsells when the crew is already on site, no “we found something” that doubles the foundation budget without documentation. If we encounter unexpected conditions, we photograph them, explain the impact, and wait for your signed approval before proceeding.
Documented Photo Record. On every visit, our technicians photograph what they found and what they did. You receive the images, not a summary of how it felt. In a recent Junior ADU conversion in the Rossmoyne neighborhood, the photo record revealed that the existing slab was 4 inches thick, within range for the conversion. We showed the homeowner the measurement, explained what it meant for the foundation line item, and proceeded with confidence. No guesswork, no dispute later.
What We Ask of You
A guarantee works both ways. We ask that you review the permitted drawings before construction begins and flag any discrepancy with your vision. We ask that you maintain access to the property for inspections, which in Glendale typically include foundation, framing, insulation, and final. We ask that you communicate concerns promptly, while the work is fresh, so we can address them under the 365-Day Done Right Promise rather than years later when memories and documentation have faded.
If you’re comparing ADU contractors in Glendale, ask each one these questions: Is your price in writing before work starts? Is your workmanship guarantee in the contract or just on the website? Who answers the phone at 10 p.m. if water is coming through a new roof penetration? At Ellery ADU Studio Glendale, the answers are yes, yes, and a live person at (424) 325-4322.
Common Questions About Our Guarantee
What does the 365-Day Done Right Promise actually cover?
It covers workmanship and compliance with the permitted drawings for one year from final inspection. If the finished ADU is not built to the approved plans, we correct it at our expense. Call (424) 325-4322 to schedule a walkthrough if you believe something’s off. Estimates for evaluation are free.
Does the guarantee cover manufacturer defects in prefab or modular units?
Manufacturer warranties from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, or James Hardie cover their own components. Our 365-Day Done Right Promise covers the installation workmanship and our coordination of those systems within your single contract. If a factory defect appears, we manage the manufacturer claim and correct any installation issue simultaneously.
What if I find a problem after 365 days?
We evaluate each call individually. Our goal is a reference, not a deadline. That said, the written promise is 365 days, and we encourage homeowners to do their final walkthrough promptly so any concern falls squarely within the guaranteed period. Call (424) 325-4322 and we’ll tell you honestly where your situation stands.
How is this different from a typical contractor warranty?
Most contractor warranties are verbal, limited to “call us if something’s wrong,” and depend on whether that contractor is still in business. We’ve been operating since 2015, our promise is in writing, and a live person answers calls 24/7. The Haven Standard clauses create accountability you can enforce, not goodwill you can hope for.
Do you guarantee the permit will be approved?
We guarantee we’ll submit a complete, code-compliant permit set and respond to city corrections promptly. Glendale’s Building & Safety Division has its own timeline, and we don’t control their queue. What we control is the quality of our submittal and our persistence through plan check. Our 900+ project history includes navigating Glendale’s hillside ordinances and fire-zone requirements successfully.
