Why Ellery ADU Studio Glendale Is Los Feliz’s Preferred New Detached ADU Company
We’ve designed, permitted, and built ADUs across Los Feliz since 2015, the year California’s ADU laws shifted statewide. That timing matters here. Los Feliz was already dense with 1920s Spanish Colonial Revival and California Craftsman homes, most with original detached rear garages on alley-accessed lots. We learned early that these structures hide outdated systems behind intact stucco, and we built our process around finding them before we quote, not after we start.
Our Los Feliz clients receive the same documentation we provide on every project: a permit set treated as the core product, a written price locked at signing under Haven Standard Clause 1, and a documented photo record on every site visit. Nadia Ellery oversees each permit strategy personally. No designer-builder blame gap. One contract, one written price, one point of accountability.

Our New Detached ADU Services in Los Feliz
Custom Built ADU
Custom built ADUs in Los Feliz start around $280,000 and scale past $480,000 for hillside lots requiring caisson foundations and Chapter 7A ember-resistant assemblies. On the flat streets near Vermont Avenue or Hillhurst, conventional framing and standard material packages clear plan check faster. On Aberdeen Avenue or any slope abutting Griffith Park, the same square footage carries a materially different structural and fire-resistance package. We engineer for your specific lot, not a template.
Prefab ADU Installation
Prefab ADU installation in Los Feliz typically runs $220,000-$350,000, depending on site access and utility routing. We specify and coordinate Abodu, Cover, and Dvele systems within our single-contract model. The advantage here is factory precision meeting Los Feliz’s compounded permitting environment: HPOZ design review for Historic Preservation Overlay Zone lots, hillside grading compliance, and Chapter 7A fire-zone detailing where applicable. We handle the coordination so the prefab delivery aligns with a cleared permit, not the other way around.
Modular ADU
Modular ADU projects in Los Feliz fall in the $240,000-$380,000 range, with crane access and utility tie-ins as the main variables. These units arrive 80-95% complete, which compresses on-site construction time. That’s valuable on tight Los Feliz alleys where staging space is limited and neighbor relations matter. We coordinate Mighty Buildings and Dvele modular systems, matching the module specifications to your lot’s structural and fire-resistance requirements before ordering.
Studio ADU & 1-Bed & 2-Bed ADU
Studio ADUs in Los Feliz typically run $220,000-$310,000; 1-bedroom units $260,000-$380,000; 2-bedroom units $320,000-$480,000. These ranges assume flat lots with conventional construction. Hillside or HPOZ lots move toward the upper end. The 1-bedroom and 2-bedroom configurations are the most common request we see from Los Feliz homeowners converting detached rear garages or building new on narrow alley-accessed parcels. Every configuration receives a permit set as the deliverable, not an afterthought.

Trusted Brands We Service in Los Feliz
We specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie within our single-contract model.

No brand is pushed. The right system for your property, your permit set, and your written price.
Common New Detached ADU Problems We See in Los Feliz Homes
- Unbraced cripple walls and missing continuous footings. Open a 1920s Los Feliz garage and you often find the original foundation was poured as a slab with no footing, and the short stud walls between slab and floor joists have no shear bracing. The City of Los Angeles won’t sign off on an ADU conversion until a seismic retrofit scope is complete. We inspect for this before quoting, write it as a priced allowance if found, and never bury it in a “contingency” line item.
- Live knob-and-tube wiring behind intact stucco. On a 1928 Spanish Colonial on Aberdeen Ave, our crew opened a detached garage for an ADU conversion and found the existing rear framing undersized for the second-story load, knob-and-tube wiring still live behind the stucco, and the flat roof assembly failing at the parapet. We stopped work, pulled a structural and electrical scope, wrote the added framing, 100-to-200-amp panel upgrade, and waterproofing repair as priced allowances approved in writing before we framed a single wall.
- HPOZ correction notices from skipped pre-application meetings. Contractors who submit garage-conversion plans in the Los Feliz HPOZ without a pre-application meeting with the Office of Historic Resources almost always receive a correction notice demanding revised exterior elevations and material callouts - a delay that can push a straightforward garage conversion past the six-month mark before a single shovel hits the ground. We schedule that meeting before the first drawing is inked.
- Chapter 7A fire-zone surprises at plan check. On the hillside streets abutting Griffith Park, a new detached ADU has to be engineered as a Chapter 7A ember-resistant assembly with multi-pane windows and enclosed eaves, while on the flat streets below the same-sized unit clears plan check under conventional detailing - the identical building on two Los Feliz lots can carry materially different framing and material packages. We verify fire hazard severity zone status in our initial site analysis so the material package and lead times are accurate in your written price.

FAQs - New Detached ADU in Los Feliz
Yes, most detached garages in Los Feliz are convertible, but the 1910s-1940s housing stock routinely reveals outdated wiring, undersized framing, and foundations without continuous footings once walls are opened. We inspect first, write any necessary seismic retrofit, electrical upgrade, or foundation repair as priced allowances, and get your written approval before touching a wall. Call (424) 325-4322 to schedule a site visit - estimates are free.
Yes, typically 15-30% more. Hillside lots abutting Griffith Park require geological reports, caisson foundations, hillside grading compliance, and Chapter 7A ember-resistant assemblies with multi-pane windows and enclosed eaves. The identical floor plan on a flat street near Hillhurst clears plan check under conventional detailing. We verify slope and fire-zone status in our initial analysis so your written price reflects the actual package, not a flat-street guess. Call (424) 325-4322 for a site-specific estimate.
Only if your property falls within the Los Feliz Historic Preservation Overlay Zone boundaries. If it does, detached-garage conversions and new ADU structures are subject to design review for compatibility with the neighborhood’s 1920s-1940s Spanish Colonial and Craftsman character. We schedule a pre-application meeting with the Office of Historic Resources before submitting drawings, which prevents the correction-notice delays that push projects past six months. Call (424) 325-4322 and we’ll confirm your property’s HPOZ status.
We stop work, document with photos, and write a priced scope change for your written approval before proceeding. No open-ended “time and materials” additions. On that 1928 Aberdeen Ave project, we found live knob-and-tube, undersized framing, and parapet failure. The client received a written allowance for the 100-to-200-amp upgrade, structural reinforcement, and waterproofing repair, approved before we framed a wall. Haven Standard Clause 5 (No Surprises) governs every change. Call (424) 325-4322 - estimates are free.
Inspection first, allowances written into the contract, and any surprise priced and approved in writing before we touch it. Older Los Feliz homes - 1920s Spanish Colonials and California Craftsmans - routinely hide systems that don’t meet current code. We build that reality into our process, not into hope. The 365-Day Done Right Promise backs the finished work in writing. Call (424) 325-4322 to discuss your property.
