We serve North Hollywood from our Los Angeles office, with crews and site assessors covering the Valley daily. Whether your lot sits off Satsuma Ave in the TOC core or south of Victory Boulevard in the postwar tracts, we know the specific DBS inspector assignments, the alley-access garage configurations, and the R2/R3 zoning overlays that shape what your permit set needs to include.

Why Ellery ADU Studio Burbank Is North Hollywood’s Preferred ADU Design & Permitting Company

We’ve designed, permitted, and built ADUs across North Hollywood since 2015 - the year California’s state ADU law shifted. That timing matters. We learned the local DBS system as it was rewriting its own rules, and we’ve tracked every subsequent ordinance update that affects Valley parcels.

North Hollywood homeowners review us consistently for one reason above others: we name the price in writing before they sign, then we build to that price. Haven Standard Clause 1 locks the scope at signing. No change orders, no door-side upsells.

Our response time to North Hollywood averages same-week site assessment availability. Dispatch and scheduling are coordinated from our Los Angeles office, with local crews who know the difference between a TOC-tier lot near the NoHo Metro B/G Line station and a standard R1 parcel south of the 134.

What builds trust here is specificity. We don’t say “we handle permits.” We say: your permit set will include the 200-amp service upgrade the inspector will flag, the Valley-grade Title 24 package with R-19 walls and R-38 roof, and the TOC density-bonus calculation if your parcel qualifies. That’s the difference between a permit set that passes and one that gets red-tagged.

Our ADU Design & Permitting Services in North Hollywood

Site Assessment

Every North Hollywood project starts with a parcel-specific site assessment. We verify your zoning (R1, R2, or R3), measure setbacks against current LA Municipal Code, check alley access for garage conversions, and confirm whether your lot falls within a TOC tier zone near the NoHo Metro B/G Line station. On a recent assessment off Satsuma Ave, our team identified TOC tier eligibility the owner hadn’t known about - unlocking a by-right JADU-plus-ADU combination that a standard design would have missed. The assessment includes a documented photo record of existing conditions, a written findings memo, and a preliminary scope with dollar ranges before you commit to full design.

ADU Design & Blueprints

Our architectural team produces permit-ready drawing sets for North Hollywood’s specific conditions. That means designing for 100°F+ summer highs with properly sized mini-split heat pump systems, not the coastal-spec single-zone units that fail Title 24 here. It means specifying stainless or hot-dip galvanized hardware for any exterior fasteners - the inland Valley heat and Santa Ana wind cycles corrode standard galvanized faster than coastal owners expect. And it means confirming your electrical service capacity upfront; most postwar North Hollywood garages run on a 60-amp subpanel off a 100-amp main, insufficient for any ADU with kitchen, laundry, and HVAC. We design the upgrade into the set from day one.

Permit Application

We file directly with LA Department of Building and Safety, not through a third-party expeditor. Our permit applications for North Hollywood include the full Title 24 energy compliance package, structural calculations for Valley seismic conditions, and - for TOC-eligible parcels - the density-bonus documentation that triggers relaxed development standards. We track the plan check timeline, respond to corrections, and coordinate the inspection sequence. Under Haven Standard Clause 5 (No Surprises), any correction that stems from our design error is our cost, not yours.

HOA & Zoning Compliance

North Hollywood’s patchwork of zoning - R1, R2, R3, and various Specific Plan overlays - creates compliance traps for generic ADU designs. We pull the certified parcel map, verify current zoning with the City Planning Department, and confirm whether your specific plan imposes design guidelines beyond the base code. For properties with HOAs, we review the CC&Rs for ADU restrictions and produce a compliance memo before design begins. This step prevents the nightmare scenario: a permitted set that the HOA blocks, or a design that misses a Specific Plan’s height district.

Title 24 Energy Compliance

North Hollywood’s inland Valley climate zone triggers stricter Title 24 requirements than coastal LA. Our energy compliance packages specify R-19 minimum wall insulation, R-38 roof insulation, and high-efficacy lighting - the standard that passes inspection here. We do not submit coastal-spec packages with lower R-values; we’ve seen those rejected at plan check, adding 4-6 weeks to timelines. The mini-split heat pump we specify is sized for the actual cooling load at 100°F+, not the milder design temperatures that work in Santa Monica or Venice.

Trusted Brands We Coordinate in North Hollywood

Ellery ADU Studio specifies and coordinates prefab and modular systems from Cover, Dvele, and Mighty Buildings within the same single-contract design-build model. For North Hollywood clients considering factory-built options, we evaluate whether the module can clear local alley widths, whether the crane placement works with your lot’s power-line geometry, and whether the manufacturer’s standard Title 24 package meets Valley-grade requirements. We don’t just drop a catalog on your desk. We model the site constraints, compare the installed price to stick-built, and document the recommendation in writing.

Common ADU Design & Permitting Problems We See in North Hollywood Homes

• Skipped 200-amp service upgrade on postwar garages. Most North Hollywood detached garages built 1945-1965 carry a 60-amp subpanel fed off a 100-amp main. That’s enough for a garage door opener and a light. An ADU with electric range, water heater, and mini-split HVAC needs 200-amp service. The DBS inspector will red-tag this before final. We design the upgrade into every permit set.
• Coastal-spec Title 24 packages submitted for Valley lots. A Title 24 package sized for coastal LA - smaller HVAC, lower R-value insulation, no dedicated cooling - fails plan check or inspection in North Hollywood. The deep Valley’s 100°F+ summer highs are not theoretical. We specify Valley-grade loads from the first submission.
• Missed TOC tier eligibility near the NoHo Metro B/G Line station. Property owners within a half-mile of the station often don’t know their lot qualifies for Transit-Oriented Communities bonuses: reduced setbacks, increased height, and by-right density. A generic ADU design ignores these entitlements. We verify TOC status in every site assessment.
• Alley-access garages designed without utility routing plans. North Hollywood’s postwar lots typically access detached garages via narrow alleys. Water, sewer, and gas extensions from the main house need specific routing that doesn’t violate utility easements. We coordinate with LADWP and LA Sanitation during design, not after construction starts.
