ADU Builders in North Hollywood - Design, Permits and Build Under One Contract

Fast, Reliable ADU Builders Across North Hollywood

ADU construction in North Hollywood typically costs between $180,000 and $420,000 depending on whether you’re converting a detached garage, building a ground-up unit, or installing a prefab, and most projects take 4 to 10 months from permit to move-in. We’re Seedling ADU Builders, and we work throughout North Hollywood on the post-WWII ranch lots that define this part of the San Fernando Valley. Your lot off Burbank Boulevard or Magnolia is not the same as one in Burbank or Van Nuys, and the way we scope it shouldn’t be either. Call (707) 383-5338 for a written price before any work starts.

Why Seedling ADU Builders Is North Hollywood’s Preferred ADU Builders Company

North Hollywood homeowners keep hiring us for a simple reason: we scope the real constraints before we quote. That means pulling LADBS panel permit history on a 1952 detached garage before we name a conversion price, checking alley-adjacent setback eligibility under LA’s ADU ordinance, and budgeting for the west-facing wall insulation and mini-split HVAC that a Valley summer demands. We’ve worked on ranch homes along Saticoy, Oxnard, and Victory, and we know what happens when someone quotes a flat price without checking the panel first.

Every project we build in North Hollywood is backed by the 365-Day Done Right Promise in writing. If it’s not done right, we make it right. You’ll also get background-checked, uniformed technicians on every visit, shoe covers and drop cloths inside your home, and a photo of the clean-up before the crew leaves. A live person answers our phone 24/7 during an active build. That matters when you’re a block from the B Line terminus and your ADU project has a question at 7pm.

ADU Contractor in North Hollywood

An ADU Contractor in North Hollywood handles the licensed build-out of a new dwelling on your lot, from foundation and framing through electrical, plumbing, insulation, drywall, and finish work. On the 6,000 – 7,500 sq ft lots that dominate neighborhoods from Valley Glen to NoHo Arts District, this usually means either converting a detached rear garage or building a new unit in the open rear yard. A ground-up detached ADU in North Hollywood typically runs $280,000 – $420,000 depending on size, lot access, and grading needs. A garage conversion typically runs $180,000 – $280,000, but only after we’ve confirmed the existing panel situation.

Garage Conversion Scoping

We pull the LADBS permit history on your existing garage before we quote. Unpermitted 60-amp sub-panels are endemic in North Hollywood’s 1945 – 1970 garages, and finding one changes the electrical scope and the timeline. If your garage opens onto a rear alley, LA’s ADU ordinance may also reduce the setbacks we need to meet, which changes where the unit can sit.

Ground-Up Detached ADU

Building new in a North Hollywood rear yard means planning access for equipment and material staging before the first trench is cut. Many of these lots are long and narrow, so we walk the site with you and mark where the mini-split, the panel, and the drainage will sit. Grading and drainage on these open rear yards are part of the written quote, not a surprise line item added later.

ADU Design in North Hollywood

ADU Design in North Hollywood means something specific here: working within the City of Los Angeles ADU rules that allow alley-adjacent detached garages reduced rear and side setbacks, and no owner-occupancy requirement on the property. That’s distinct from Burbank or Van Nuys, which are separate cities entirely outside LA’s ADU ordinance. Our design process starts with the lot, not the floor plan. We look at alley access, rear yard depth, the existing panel, and the west-facing exposure that afternoon Valley heat will hit. A design-and-engineering package for a North Hollywood ADU typically runs $12,000 – $28,000 depending on whether it’s a conversion, a ground-up unit, or a prefab install.

Lot-Based Design First

We measure the rear yard and confirm the legal setbacks before we draw anything. On a 1950s ranch near Saticoy, the alley-adjacent garage got reduced setback treatment under the LA ordinance, which let us design a second detached unit behind it. Without that early check, the design would have been wrong from the start.

Climate-Ready Interiors

West-facing garage walls with original uninsulated drywall are a recurring problem in North Hollywood conversions. We specify dedicated mini-split HVAC and proper attic insulation on every design, because a unit that can’t stay cool through a 105°F+ July week is not rentable and may fail habitability inspection. This is not an optional upgrade here.

Trusted Brands We Service in North Hollywood

We work hands-on with the ADU brands serious North Hollywood buyers research before calling anyone, including Abodu, Cover, and Dvele. For a garage conversion or a ground-up build, those prefab and panelized systems can shorten the on-site phase meaningfully. But we don’t sell you a brand because it’s sitting in a warehouse. We help you choose the right product for your specific lot, your alley access, and your panel capacity. We also service and install these systems locally, so replacement parts and warranty work don’t mean waiting on a crew from another county.

Common ADU Builders Problems We See in North Hollywood Homes

• Unpermitted 60-amp garage sub-panels. These show up constantly in the 1945 – 1970 detached garages along the B Line corridor. We pull the LADBS permit history before quoting, because a mandatory service upgrade will add three to six weeks to your timeline and change your number.
• West-facing uninsulated garage walls. Original drywall on a west wall bakes through Valley summer afternoons. Without dedicated mini-split HVAC and proper insulation, the converted unit will be functionally unrentable in July and August and may not pass habitability inspection.
• Alley-adjacent setback confusion. North Hollywood’s ranch homes often have detached garages opening onto rear alleys. LA’s ADU ordinance grants favorable setback treatment to these structures, but if the designer doesn’t check the alley access and the existing panel history first, the plan can get rejected or the quote can come back wrong.
• Narrow-lot equipment access. On a 6,000 – 7,500 sq ft lot with a long rear yard, getting equipment and materials to the back without tearing up the yard takes real planning. Grading and drainage on the open rear yard also affects where the structure can legally sit and where stormwater goes.
