Get your free estimateFast, Reliable ADU Builders Across North Hollywood
Most ADU projects in North Hollywood start with one question: can I convert my existing detached garage, or do I need to build new in the backyard? The answer changes the budget by tens of thousands of dollars, and it hinges on your specific lot lines, rear-yard setback, and how your garage sits relative to the alley. That’s what we sort out first, before anyone gives you a number. Our crews work North Hollywood neighborhoods including the NoHo Arts District, Valley Glen, and the streets off Burbank Boulevard and Vineland Avenue regularly, and we know which lots trigger which plan-check reviews. Call (361) 315-4177 and we’ll walk your property and tell you what’s actually feasible. Not what sounds good. What will pass.
Why Fielding ADU Builders Is North Hollywood’s Preferred ADU Builders Company
Fielding ADU Builders operates inside the Garrison Partners family, and we hold ourselves to The Garrison Standard. That means written pricing before any work starts, permitted construction done by the book, and a one-year written guarantee on the finished ADU. Reed Calloway leads our team, and he’s the person who signs off on every North Hollywood scope we produce. Homeowners here tell us the same story again and again: a previous contractor quoted a number, started digging, then came back with a change order when the trench hit a root or the panel needed an upgrade. We flag those costs in the written estimate, not after the concrete is poured.
Every crew member who steps onto a North Hollywood property is background-checked, uniformed, and knows the job plan before arrival. You’ll know who’s on your site by name. And when you call (361) 315-4177, a live person answers – noon or midnight – not a voicemail queue. We coordinate scheduling from the brand’s Los Angeles office, so a project manager is never more than a short drive from your address when something needs a second look.
ADU Design in North Hollywood
ADU Design in North Hollywood is where a project either gets done right or goes sideways before anyone swings a hammer. On postwar tract lots, the design phase determines whether your existing detached garage can convert cleanly or whether a backyard build is the better path, and that decision locks in your price. We charge design separately from build, and we’ll give you the design price in writing after the first site visit. A typical ADU design package for a North Hollywood project runs $8,500 to $18,000 depending on whether we’re drawing a garage conversion, a custom backyard unit, or a prefab panelized layout, with structural engineering and permit-ready drawings included.
Feasibility first
We do not draw anything until we have measured the actual lot. Rear-yard setbacks, side-yard clearances, and the distance from your garage door to the alley all get checked against current Title 24 and North Hollywood building-code requirements. If a garage conversion is the only way to get a compliant ADU without triggering a replacement-parking requirement, we tell you that on day one.
Design for the lot you have
In North Hollywood, most lots run about 50 feet wide on paper and feel narrower once you account for driveway access and existing structures. The design phase is also when we confirm whether a setback variance (the city’s written permission to build closer to the property line than the standard rule allows) is necessary, and whether that variance will add plan-check time.
Backyard ADU in North Hollywood
Backyard ADU in North Hollywood construction means a new detached unit in the rear yard, typically 400 to 800 square feet, with its own utility trench tied back to the main house panel. It’s the right call when the existing garage sits inside the required setback and cannot convert, or when you want a full-height structure with more square footage than a garage shell allows. A custom backyard ADU in North Hollywood generally runs $250,000 to $420,000 before permit fees, depending on site access, soil condition, and how far the utility trench must run.
Utility runs decide the number
The trench from the main house to the backyard ADU is the single biggest silent cost driver in North Hollywood. A 60-foot run through open soil is one thing; a 40-foot run under a concrete patio with a sewer line crossing it is another. We price the trench with an allowance for what we find, and we show you the per-foot rate in writing so you know exactly how the number moves.
Panel upgrades and power
Most 1950s-era North Hollywood homes still carry a 100-amp panel, which is rarely enough to feed a separate dwelling unit. We inspect the panel during the initial walkthrough and include any upgrade in the written estimate. Nothing about your electrical load should be a discovery item once excavation starts.
Trusted Brands We Service in North Hollywood
Our ADU Builders team works with the major prefab and modular platforms North Hollywood homeowners are already researching. For detached backyard units, we install and finish Abodu and Cover modules, including foundation, utility tie-in, and final interior work. For larger panelized builds, we work with Dvele and Mighty Buildings systems, and we frame conventional structures with James Hardie siding where a custom look is the priority. We know which brands clear North Hollywood plan check faster and which ones match the setback constraints of a standard 50-foot lot. When you call (361) 315-4177, we’ll tell you which one fits your lot and budget – not whichever one a manufacturer’s rep is pushing this month.
Common ADU Builders Problems We See in North Hollywood Homes
- Garage setbacks that flip the whole plan. Many North Hollywood garages sit within three feet of the rear lot line, which is inside the current setback for new construction. A garage conversion often becomes the only compliant ADU path, and that changes the scope and the price. We check this before quoting anything.
- Alley-adjacent access triggering parking reviews. If your garage opens onto an alley, the driveway approach and replacement-parking analysis go through a separate plan-check cycle. We’ve seen quotes miss this entirely, then the client gets a notice from the city six weeks in. We flag it in the estimate.
- Undersized electrical panels on postwar homes. A 100-amp panel that’s worked fine for fifty years will not carry an ADU with a kitchen and a mini-split. We inspect the panel during the first visit and put the upgrade in writing.
- Utility trenching costs hiding inside low bids. Running water, sewer, and electrical from the main house to a detached ADU across North Hollywood’s compacted clay soil is real labor, and it’s not cheap. We show you the trench rate per foot so you can compare bids honestly.

FAQs About ADU Builders in North Hollywood
Yes, in most cases you can, and it’s usually the lower-cost path. The key question is whether your garage sits outside the required rear and side setbacks. Many North Hollywood garages sit close to the lot line, and when that’s true, conversion is often the only compliant way to add an ADU without triggering a replacement-parking requirement. We’ll measure it during the free site visit and tell you what will pass. Call (361) 315-4177 to schedule yours.
A typical North Hollywood ADU goes through foundation inspection, framing inspection, rough electrical and plumbing, insulation, and a final building inspection, plus separate utility sign-offs. If your lot has alley access, expect an additional zoning and driveway-approach review. We pull the permits, call the inspections, and stay on site until each one clears. The Garrison Code applies here: by the book, no exceptions.
Plan on six to nine months from the first design meeting to final inspection. Design and permit submittal typically take two to three months, plan check another four to eight weeks depending on the current queue in North Hollywood, and construction runs three to five months for a garage conversion or prefab backyard unit. Custom backyard builds on difficult lots can stretch longer. We’ll give you a written schedule before work starts and hold to it.
Nothing, unless you change the scope or we hit a condition that could not have been seen before excavation. That’s why we inspect your lot, your panel, and your garage setbacks before we quote. We recently rebuilt a failing 1950s detached garage into a one-bedroom ADU off the alley side in the NoHo Arts District, and because we scoped it as a garage conversion with a reused slab footprint where it passed, the client never faced a change order. If something subsurface shows up, we show it to you and price the fix before we proceed.
Yes. Prefab and panelized units from Abodu, Cover, and Mighty Buildings work on many North Hollywood lots, particularly in the Valley Glen and NoHo Arts District areas where rear access is open enough for a module delivery. The restriction is usually crane access or a narrow side yard, not the unit itself. We’ll tell you during the first visit whether a prefab build saves you money on your specific lot or whether a conventional build makes more sense. Call (361) 315-4177 to find out.
