Frequently Asked Questions

From signed contract to certificate of occupancy, most West Hollywood ADUs take 12-18 months. Permitting through the city's Planning and Building Services typically runs 4-6 months, with construction adding 8-12 months depending on complexity. Pre-approved designs can shave 2-3 months off the front end. We provide a written schedule with named milestones before we start, and we text you when crews are on the way. Delays happen, but we document the cause and the revised timeline in writing.

A design-build studio holds one contract for drawings, permits, and construction. A traditional contractor builds from plans created by a separate architect or designer. The ADU projects that go wrong are almost always the ones where the designer and the builder can each blame the other. With us, the permit set and the build price are developed together, so the drawings we submit are the ones we know we can build for the quoted price. That's why Ellery was founded in 2015, the year California's ADU law changed and the permitting queue became the actual product.

We pull every permit and schedule every inspection. Our permit set is included in our flat price, and we manage the plan-check revisions that West Hollywood's Building Division typically requests. You attend the final inspection if you want to, but you don't manage the process. We leave you with a documented record: permit numbers, inspection sign-offs, and photos of what we actually found and fixed. That's Clause 4 of The Haven Standard.

Yes, though hillside construction requires geotechnical reports, engineered retaining walls, and often LADWP or county drainage approvals in addition to city permits. West Hollywood's northern neighborhoods border the Hollywood Hills, and we've worked on sloped lots there. The foundation system drives cost more than the structure itself on these sites. We evaluate slope, soil, and access during our initial site visit and build those findings into the written quote.

Call (213) 329-7167 to schedule a free site evaluation. We'll walk your property, check setbacks against the current zoning map, identify utility locations, and flag any obvious constraints. Within a week, you'll receive a written feasibility summary with a rough price range. If you move forward, we develop the permit set and fixed-price contract. If you don't, you keep the summary. No charge either way.

We do both, depending on site constraints and owner preference. Stick-built on-site works best for irregular lots, custom designs, and properties with limited crane access. Prefab options from brands like Abodu or Cover can reduce construction time by 30-50% on flat, accessible sites with standard utility connections. We evaluate access, setback clearances, and your design goals before recommending either path. The permit process is similar; the difference is in how much happens in a factory versus in your yard.

James Hardie fiber-cement siding performs well here. It handles the dry heat, occasional Santa Ana wind, and UV exposure without the warping or pest issues that can affect wood in Southern California. For smaller studio units, Tuff Shed's engineered panel systems offer a cost-effective option when the design is simple and the aesthetic fits. We specify materials in the written scope, with alternatives at different price points, so you see the trade-offs before deciding.

You can, with conditions. Owner-supplied items must arrive on schedule and meet the specifications in our permit set. Delays or mismatched specs hold up the job, and we charge for crew standby time. Most West Hollywood clients prefer we source through our trade accounts, which include warranty support and replacement guarantees. If you have specific fixtures in mind, we build them into the written scope with a clear procurement timeline.

Yes. Every pro working under our name is required to hold the license and insurance California requires for ADU construction, including a valid B-General Building Contractor license and current workers' compensation coverage. We provide license numbers and certificate of insurance on request. Our local branch operates independently under the standards and documentation systems that Ellery ADU Studio established in 2015.

Yes. We maintain general liability coverage appropriate for residential construction in Los Angeles County. We name property owners as additional insureds on the certificate for the duration of the project. Documentation is available before contract signing. This is standard for reputable builders in West Hollywood and surrounding cities like Beverly Hills, Culver City, and Santa Monica.

Most standard policies do not cover active construction or builder-caused damage. We require proof of your existing coverage and provide our certificate so your agent can confirm gaps. For major additions, we sometimes recommend a course-of-construction policy, which we can help you source. We document existing conditions with photos before we start, so there's a clear record if questions arise.

Contact your project manager directly. For urgent structural, utility, or safety issues, we respond during our operating hours: Monday through Friday 7:30 AM - 7:30 PM, Saturday and Sunday 8:30 AM - 7:30 PM. Our coordinator connects you with the local team; the person who answers knows your project. We document what we find, fix it, and record the resolution. Clause 4 of The Haven Standard requires evidence on every job.

We prioritize warranty and callback service for past clients. For genuine emergencies, water intrusion or structural concerns, we respond as quickly as our schedule allows during the hours listed above. We are not a 24/7 emergency contractor; for after-hours situations requiring immediate response, we refer you to appropriate emergency services and follow up during business hours. Our strength is planned, permitted work done right the first time.

Your project manager provides direct contact information and typically responds to texts and calls within the same business day. For scheduling questions, our coordinator handles crew dispatch and can confirm arrival windows. We send a text when crews are on the way, with a named technician and estimated arrival. No dispatch center runaround, just the local team managing your job.

Every ADU we build carries a written workmanship warranty, with terms specified in your contract before work starts. Structural elements, waterproofing, and mechanical systems carry different coverage periods, all documented in writing. We don't ask you to trust a verbal promise; Clause 1 of The Haven Standard requires the warranty in the same document as the price and scope. If something fails due to our work, we fix it and document what we found.

The Haven Standard is our five-clause commitment: Clause 1, Have it in writing, flat price, written scope, written warranty before anyone starts; Clause 2, Arrive on schedule, a real window, a named tech, a text when they are on the way; Clause 3, Verified crews, licensed, insured, background-checked, license number on the page; Clause 4, Evidence on every job, photos and readings of what we actually found; Clause 5, No surprises, no door upsell, no scope creep, no "while we are in here." Every Ellery ADU Studio branch works to this standard, including ours in West Hollywood.

Our workmanship warranty transfers to the new owner with proper documentation. We provide a warranty certificate and project record at completion, which you can hand to buyers or their inspector. In West Hollywood's active real estate market, a permitted, documented ADU with a transferable warranty adds measurable value. We've seen this play out in sales from the Hollywood Hills to Beverly Grove. The permit history and our documentation prove the unit was built to code.

We guarantee we'll submit a complete, code-compliant permit set and manage the revision process until approval. If West Hollywood's Planning or Building Division requires changes, we make them at our cost. We don't guarantee timelines controlled by city staffing or policy shifts, but we do guarantee we'll navigate the process professionally and document every step. Since 2015, Ellery ADU Studio has designed, permitted, and built over 900 ADUs with a written price before we started and a documented record when we left.
