Frequently Asked Questions - ADU in North Hollywood, CA
We've been designing, permitting, and building ADUs across the San Fernando Valley since 2015. Below are the questions we hear most from North Hollywood homeowners researching their project.
Pricing & Cost FAQs
A detached ADU in North Hollywood typically runs between $250 and $450 per square foot depending on site conditions, finishes, and whether you're building new or converting an existing garage. A 500-square-foot one-bedroom unit usually lands in the $125,000-$225,000 range. We've priced jobs lower where the garage slab and electrical panel were already in good shape, and higher on hillside lots in the foothills near Studio City where grading and retaining walls added scope. Every quote we deliver is flat price and written, per Haven Standard Clause 1, before anyone breaks ground. Call (424) 407-8266 and we'll walk your property to give you a real number.
No. Our flat-price contract includes the full permit set, city fees, construction, and finish work. What we quote is what you pay. The only changes happen if you add scope after signing, like upgrading from vinyl flooring to engineered hardwood, or if the city requires unexpected seismic work after we open walls. In 11 years, we've documented every surprise we found and showed the homeowner photos before any cost moved. Haven Standard Clause 5, No Surprises, means no door upsell and no "while we're in here." Call (424) 407-8266 for a written estimate with every line item visible.
Yes, most North Hollywood ADUs pay back their construction cost in rental income within 7-12 years, and they add significant resale value in a market where buyers specifically search for income potential. The real return depends on your rental strategy: long-term tenants in North Hollywood's rent-controlled market, short-term rentals where permitted, or family use that replaces a separate housing payment. We don't sell appreciation promises; we show you the actual rental comps on your block and let the math speak. Call (424) 407-8266 and we'll pull comparable rents within a half-mile of your property.
Yes, most of our North Hollywood clients use a combination of home equity lines, construction loans, or California's CalHFA ADU Grant program, which offers up to $40,000 for pre-development costs. Some lenders specialize in ADU-specific products because the income potential makes the loan math work differently than a kitchen remodel. We don't broker loans, but we can share the lenders our clients have actually closed with and what documentation they needed from us. Call (424) 407-8266 and we'll point you toward options that match your project timeline.
Service & Process FAQs
From signed contract to certificate of occupancy, most North Hollywood ADUs take 12-18 months. The permitting phase with the City of Los Angeles Department of Building and Safety typically runs 4-8 months, depending on whether your lot is in a hillside zone or requires a coastal exemption review. Construction itself usually takes 6-10 months for a detached unit. We've had garage conversions move faster when the foundation and utilities needed minimal work, and we've seen complex hillside jobs in the Hollywood Hills stretch longer. We give you a real schedule in writing at contract, not a best-case fantasy. Call (424) 407-8266 to review your property's specific timeline.
A design-build studio handles architecture, engineering, permitting, and construction under one contract with one price. A traditional contractor builds from plans you bring them, which means if the city rejects the drawings or the builder finds a conflict, the designer and contractor can each blame the other while your project stalls. Ellery ADU Studio was built this way in 2015 specifically because California's ADU law change created a permitting queue that became the actual product. One contract, one price, one throat to choke. That's Haven Standard Clause 1 in practice. Call (424) 407-8266 to see how the process works for your lot.
We handle everything. Our in-house designers produce the full permit set, including structural calculations, Title 24 energy compliance, and landscape plans if required. You don't hire a separate architect or expeditor. We've been working with the City of Los Angeles plan checkers since 2015, and we know which details trigger questions on Tujunga Avenue versus which ones sail through. The permit fees are included in your flat price. Call (424) 407-8266 and we'll check your address against current zoning and utility capacity.
Yes, garage conversions are often the fastest and most cost-effective ADU path in North Hollywood, especially in neighborhoods like the NoHo Arts District where lot sizes are tight and detached new construction may not fit. We assess the existing slab, roof structure, and electrical service to determine what's reusable. Many 1950s garages in Valley Village and Sherman Oaks need panel upgrades and seismic bolting to meet current code, which we factor into the written quote upfront. Call (424) 407-8266 to schedule a site evaluation of your garage.
We walk your property, measure the lot and any existing structure, photograph conditions, and flag obvious constraints like overhead power lines, slope, or setback issues. Within a week, you receive a written feasibility summary with rough square footage potential, a preliminary floor plan option, and a price range. There's no charge for this visit and no pressure to move forward. We document what we found with photos, per Haven Standard Clause 4, so you have evidence of conditions whether you hire us or not. Call (424) 407-8266 to book your walkthrough.
Brands & Parts FAQs
We specify materials for durability in Southern California's climate, not for brand recognition. For siding, we often use James Hardie fiber-cement products because they handle the Valley's heat and occasional Santa Ana wind-driven rain better than vinyl or wood. For prefabricated structural components on tight-access lots, we've worked with Tuff Shed and Abodu for their engineered panel systems that reduce on-site construction time. Windows are typically vinyl-framed, dual-pane, with low-E coating for Title 24 compliance. Every material is listed in your written scope with model numbers, so you know exactly what you're getting. Call (424) 407-8266 to review specifications for your project.
We do both site-built and prefab depending on site access, timeline, and budget. Prefab units from brands like Cover or Abodu can cut construction time by 30-50% when crane access is straightforward and the foundation is simple. Site-built makes more sense on hillside lots, tight alley-access properties in North Hollywood's older neighborhoods, or when you want custom dimensions that don't match prefab modules. We evaluate your specific lot and give you an honest comparison, not a sales pitch for whichever product we prefer. Call (424) 407-8266 to discuss which approach fits your property.
Yes, within the allowances specified in your contract. We tier our finish packages, and you select from those tiers or pay the difference for upgrades. Some clients in Beverly Hills and West Hollywood want higher-end tile and plumbing fixtures; others in Van Nuys and Northridge prioritize rental durability over aesthetics. Either way, selections are locked before construction starts so there's no delay from decision paralysis mid-project. Haven Standard Clause 1 means your choices are documented in writing, not remembered from a conversation. Call (424) 407-8266 to see our standard finish packages.
Licensing & Insurance FAQs
Yes. Every pro working under our name in North Hollywood is required to hold the California contractor license and insurance that state law requires. Nadia Ellery leads the local branch, and our crews carry general liability, workers' compensation, and commercial auto coverage. We don't publish individual license numbers online, but we provide them in writing with every quote for your verification. This is Haven Standard Clause 3: verified crews, with documentation you can check. Call (424) 407-8266 and we'll send you our certificate of insurance directly.
We pull every permit required for your project, including building, electrical, plumbing, and mechanical. The permit fees are included in your flat price. We also schedule all inspections and meet the inspector on site. In Los Angeles, this matters because failed inspections can add weeks to your timeline if the contractor isn't familiar with the specific inspector's expectations. We've been working with LADBS since 2015, and we know which details get flagged in North Hollywood versus Glendale versus West Los Angeles. Call (424) 407-8266 and we'll explain the permit path for your specific address.
Your homeowner's policy should cover the existing structure during construction, but you should notify your carrier that work is happening. We carry builder's risk coverage for the new construction itself, and our general liability covers damage we cause to your property. We don't give insurance advice, but we do provide our certificate of insurance and a summary of what each policy covers so you can have an informed conversation with your agent. Documentation is Haven Standard Clause 4. Call (424) 407-8266 and we'll send you our insurance packet.
Emergency & Response FAQs
Call us immediately at (424) 407-8266. Our phone is answered 24 hours a day, every day of the week. For urgent issues like water line breaks or exposed electrical hazards, we dispatch the trade responsible within hours. For non-urgent concerns like finish discrepancies or scheduling questions, we respond by the next business day with a specific plan. Every job has a dedicated project manager with a direct number, and Haven Standard Clause 4 requires photo documentation of what we found and what we did. Problems happen in construction; how they're handled separates professionals from the rest.
Yes, our phone line at (424) 407-8266 is answered live 24 hours a day, Monday through Sunday. You'll reach a coordinator who connects you with the appropriate local team member, not a voicemail system. For true emergencies during active construction, like a broken water main or exposed live wiring, we have protocols to reach the on-call trade. For planning questions or non-urgent scheduling, we may take a message and have your project manager return the call during business hours. The point is: you're never waiting until morning with no one to talk to. Call (424) 407-8266 any time.
Yes, though pauses create costs. We can secure the site, cover incomplete work, and resume when you're ready. The contract specifies hold fees for extended pauses, typically covering site security, insurance continuation, and material storage. We've worked with homeowners in Tarzana and West Los Angeles who needed to refinance mid-project, and we structured the pause to protect the work already in place. The key is communicating early, not after the next trade is scheduled. Call (424) 407-8266 to discuss how we'd handle your specific situation.
Warranty & Guarantees FAQs
We provide a written workmanship warranty on every ADU we build, with specific coverage periods for different systems: typically one year on general workmanship, two years on mechanical systems, and longer on structural elements where California law requires it. The exact terms are in your contract, not a vague promise. Haven Standard Clause 1 requires everything in writing, and Clause 5 means no surprise exclusions when you actually need service. We've been building ADUs since 2015, and we're still here for clients from our earliest projects. Call (424) 407-8266 and we'll send you a sample warranty document.
Yes, our workmanship warranty transfers to the new owner with written notification from you. This matters in North Hollywood's active real estate market, where buyers increasingly ask about ADU warranty status during due diligence. We keep digital records of every job since 2015, so we can verify coverage and conditions for any future owner. Transferring the warranty requires a simple form; there's no fee. Call (424) 407-8266 and we'll explain the process.
You call (424) 407-8266, describe the issue, and we schedule an inspection within a few business days. If it's our work, we fix it at our cost. If it's normal maintenance or damage from external causes, we show you photos and explain why. Haven Standard Clause 4 requires evidence on every job, and that documentation helps us diagnose whether a crack is settling or a defect, whether a leak is from our flashing or a new roof impact. We don't debate; we investigate and show you what we found. Call (424) 407-8266 to report any concern.
The Haven Standard is our documented system for how every ADU project is sold, built, and closed out. It's not a single warranty document; it's five clauses that govern the entire relationship: written price before start, scheduled arrival with named crews, verified licenses and insurance, photo evidence of conditions and work, and no surprises in scope or billing. The brand name Ellery comes from a founder's surname, used the way design practices use them, because an ADU is a year-long relationship and a six-figure decision. People want to know whose practice it is. Call (424) 407-8266 to see how Haven Standard applies to your project.
