Why Los Feliz Homes Are Different
Los Feliz sits at the intersection of three forces that reshape every ADU project. First, the hillside slopes abutting Griffith Park fall within LA’s Very High Fire Hazard Severity Zone, so any new structure or conversion must meet Chapter 7A ember-resistant assemblies - ignition-resistant siding, multi-pane windows, enclosed eaves - adding material cost and lead time that flat-street ADUs avoid. Second, the Los Feliz Historic Preservation Overlay Zone subjects detached-garage conversions and new structures to design review for compatibility with Spanish Colonial and Craftsman character, requiring pre-application meetings with the Office of Historic Resources before plan submission. Third, the 1910s-1940s housing stock means original knob-and-tube wiring, unbraced cripple walls, and 100-amp panels are standard - each a permit-blocking condition until addressed. We’ve seen contractors skip the HPOZ pre-application and receive six-month correction notices. We don’t.
Our Main Los Feliz Services
Los Feliz homeowners call us most often for two services, with three additional ADU types each holding their own page.
ADU Design & Permitting in Los Feliz
Our permit set is the core product, not an afterthought. In Los Feliz, that means navigating both the LA Hillside Construction Regulations for sloped parcels and the HPOZ design review for historic-area properties. We produce the full architectural, structural, and MEP drawings, then shepherd them through LADBS and the Office of Historic Resources. Every set includes the documentation the city requires for your specific lot. ADU Design & Permitting in Los Feliz covers the full process.
Garage Conversion ADU in Los Feliz
Los Feliz’s alley-accessed detached rear garages are the neighborhood’s most common conversion candidate. These structures routinely need 200-amp panel upgrades, foundation leveling, and seismic cripple-wall retrofits before LADBS will sign off. We assess the existing slab, roof structure, and utility capacity in the first site visit, then quote a single written price for drawings through final inspection. Garage Conversion ADU in Los Feliz details our process.
New Detached ADU in Los Feliz
Sloped lots near Griffith Park require geological reports and caisson foundations under the Hillside Construction Regulations, while HPOZ parcels face design-review scrutiny for exterior materials and massing. We coordinate geotechnical referrals, produce permit-compliant elevations, and specify ignition-resistant assemblies from the start. New Detached ADU in Los Feliz explains how we manage both burdens under one contract.

Junior ADU & Interior Conversion in Los Feliz
Junior ADU & Interior Conversion in Los Feliz solves a specific problem: homeowners who want rental income or family housing without touching the garage or building new in the yard. The neighborhood’s 1910s-1940s homes contain basements, attics, and underutilized rooms that convert well, but original knob-and-tube wiring, low ceilings, and non-conforming egress windows are nearly universal. We assess which interior spaces qualify under California’s JADU code - a bedroom or similar area within the existing footprint, with separate exterior access - then produce the permit set and construction documents as a single deliverable. Junior ADU & Interior Conversion is our dedicated service hub for this work.
Basement ADU
Signs you need it
Your basement has headroom below 7 feet 6 inches, moisture staining on foundation walls, or a single exit with no egress window.
What it costs in Los Feliz
Basement ADU conversion in Los Feliz typically runs $95,000-$175,000 all-in, including excavation for proper ceiling height, waterproofing, and egress window installation.
How we do it
We measure existing headroom, specify underpinning or bench-footing where needed, install perimeter drainage and vapor barriers, then frame, rough-in MEP, and finish to match the main house.
Room-to-ADU Conversion
Signs you need it
You have a ground-floor bedroom or den with direct exterior access potential and a separate entrance that could be added without altering the roofline.
What it costs in Los Feliz
Room-to-ADU conversion in Los Feliz typically runs $75,000-$140,000 all-in, including kitchenette, bathroom rough-in, and separate meter or sub-meter installation.
How we do it
We verify the space meets JADU square-footage limits, design the kitchenette and wet-wall layout, pull the permit set, and build to the documented scope with photo records at each inspection.
What Junior ADU & Interior Conversion Costs in Los Feliz
| Item | Typical range in Los Feliz |
|---|---|
| Basement ADU conversion | $95,000 - $175,000 |
| Room-to-ADU conversion | $75,000 - $140,000 |
| Egress window installation (per window) | $4,500 - $8,500 |
Does a Junior ADU need its own meter in Los Feliz?
No - California JADU law allows a sub-meter or shared utility arrangement with the main dwelling, though many Los Feliz owners opt for separate meters to simplify tenant billing. Call (424) 325-4322 and we’ll review your panel capacity and quote both options in writing.
Can I convert any room into a Junior ADU?
No - the space must be within the existing footprint, have exterior access, and the owner must occupy either the main house or the JADU. We assess qualifying rooms during our first site visit and document what works. Call (424) 325-4322 for a free evaluation.
ADU Site Prep & Utilities in Los Feliz
ADU Site Prep & Utilities in Los Feliz addresses the conditions that stop construction before it starts: hundred-year-old foundations, undersized electrical panels, and hillside grading that triggers geotechnical requirements. The neighborhood’s 1910s-1940s housing stock routinely presents 100-amp panels, galvanized plumbing laterals, and unbraced cripple walls - each a code violation that LADBS will flag before issuing a construction permit. We handle these as standalone preparatory work or bundled into the full ADU contract, with a written price before any work begins. ADU Site Prep & Utilities covers our full scope.
Electrical Panel Upgrade
Signs you need it
Your panel is rated at 100 amps, has fused rather than breaker-based protection, or shows scorch marks around bus bars.
What it costs in Los Feliz
Electrical panel upgrade in Los Feliz typically runs $4,500-$9,500 for 200-amp service, including permit, inspection, and utility coordination with LADWP.
How we do it
We verify load calculations for the ADU plus main house, specify the new panel and grounding system, pull the permit, and coordinate LADWP disconnect and reconnect.
Foundation & Grading
Signs you need it
Your garage slab measures less than 4 inches thick, shows vertical cracking wider than 1/4 inch, or sits on a hillside lot with visible slope creep.
What it costs in Los Feliz
Foundation and grading work in Los Feliz typically runs $12,000-$35,000 for garage slabs, and $25,000-$75,000 for hillside caisson or pier foundations requiring geotechnical oversight.
How we do it
We engage a geotechnical engineer for hillside parcels, produce the grading and foundation plan as part of the permit set, and build to the engineered specifications with inspection hold points.
What ADU Site Prep & Utilities Costs in Los Feliz
| Item | Typical range in Los Feliz |
|---|---|
| Electrical panel upgrade (100A to 200A) | $4,500 - $9,500 |
| Foundation and grading (garage slab) | $12,000 - $35,000 |
| Foundation and grading (hillside caisson) | $25,000 - $75,000 |
Will LADWP require a new service drop for my ADU?
Not always - many Los Feliz ADUs run on a panel upgrade with existing service capacity, but overloaded transformers in older neighborhoods sometimes trigger LADWP infrastructure charges. We verify this with a service-request letter before quoting. Call (424) 325-4322 for a written assessment.
How long does site prep take before construction starts?
Typical site prep in Los Feliz runs 3-6 weeks for panel upgrades and slab work, and 8-14 weeks for hillside foundations requiring geotechnical reports and grading permits. We sequence this work so construction follows immediately after final inspection. Call (424) 325-4322 to schedule.
Brands We Service in Los Feliz
We specify and coordinate prefab and modular systems from Tuff Shed, James Hardie, and Abodu within our single-contract model, with parts and assemblies stocked through Los Angeles-area distributors. Turnaround on brand-specific material orders typically matches standard lead times once the permit set is approved. See our brands for full compatibility details.

FAQs About ADU in Los Feliz
Standard LADBS plan check runs 8-16 weeks, but Los Feliz HPOZ properties add 4-8 weeks for Office of Historic Resources design review. Hillside parcels trigger additional geological and grading plan checks. We schedule pre-application meetings to prevent correction-notice delays.
California law prohibits HOAs from outright banning ADUs, but Los Feliz’s few remaining covenants may impose design guidelines. We review your title report and CC&Rs during the initial consultation, then design to satisfy both the covenant and the city code.
