Fast, Reliable Home Addition Contractor Across Burbank
Adding a room or a second story to a Burbank home costs between $85,000 and $450,000 depending on scope, with most single-room additions landing between $120,000 and $180,000. The bigger variable isn’t the square footage; it’s what the walls hide once they’re open. Burbank’s housing stock runs heavily toward 1940s and 1950s ranch homes and bungalows, and those houses carry original electrical service, outdated framing, and waterproofing that failed quietly for decades before anyone noticed. We’re Seedling ADU Builders, and our Home Addition Contractor team serves Burbank with written pricing before work starts and a 365-Day Done Right Promise on every completed job. Call us at (707) 383-5338 to schedule a free estimate.

Why Seedling ADU Builders Is Burbank’s Preferred Home Addition Contractor Company
Burbank homeowners call us because we speak the language of their specific houses. We know what a 1947 Magnolia Park ranch looks like behind the drywall, because we’ve opened dozens of them. We know which streets fall inside the Hollywood Burbank Airport noise-contour overlay and which don’t, and we pull that map before we quote anything. That’s the kind of local knowledge that keeps an addition from stalling at plan check or blowing past its budget mid-framing.
Ben Ortega leads our Burbank projects personally, and every crew member who walks through your door is background-checked and uniformed. The Cedarwell Care Promise applies to every visit: shoe covers and drop cloths inside your home, pet-safe products wherever there’s a choice, and a photo of the clean-up before the crew leaves each day. We’re an independently owned and operated member of the Cedarwell family of companies, established in 2001, and live phone support runs 24/7 throughout your build, so a real person answers when you call about a question at 7 a.m. before school drop-off.
Burbank families with kids and pets care about how the house is left at the end of every workday. So do we. Floors stay protected, air stays as clean as active construction allows, and nobody has to wonder who’s in the house.
Room Addition Contractor in Burbank
A Room Addition Contractor in Burbank works on the most common project we see here: adding a primary suite, a family room, or an extra bedroom onto a single-story home that’s run out of space. In Burbank, the typical ground-floor room addition runs $120,000 to $200,000, depending on whether a bathroom is included and whether the parcel sits inside the ALUCP noise contour. The airport overlay matters more than most homeowners expect, because it upgrades the window spec, the wall assembly, and the HVAC design on every new habitable room. We quote it correctly the first time.
Adding Space Without Leaving the Lot
Most Burbank homeowners aren’t moving. They like their street, their schools, their commute to the studios. A room addition keeps them in the house they already own while giving a growing family the square footage they need. On modest lots in Magnolia Park or south of Olive Avenue, a well-planned addition can double a home’s usable living area without touching the backyard footprint more than necessary.
What a Burbank Room Addition Involves
Foundation work, framing, roofing tie-ins, electrical, insulation, drywall, and finish work are all part of it. The permit process in Burbank is thorough, and if your home still runs on a 60-amp or 100-amp panel, that upgrade is almost certainly coming with the permit. We build those allowances into the written price before work begins, so the panel isn’t a surprise line item the week the electrician shows up.
Second Story Addition Contractor in Burbank
A Second Story Addition Contractor in Burbank handles projects where a lot is too small to build outward, so the only direction is up. Burbank’s ranch homes sit on compact lots, and when a family needs two or three more bedrooms, going vertical often makes more sense than sacrificing the backyard. Second-story additions in Burbank typically run $250,000 to $450,000. The structural work is more involved, but for many households, it’s the best use of the lot they already own.
Structural Reality on 1950s Ranch Homes
Many Burbank ranches were never engineered for a second floor. The footings and first-floor walls often need reinforcement before the upper level goes on, and that work has to be engineered and permitted properly. We handle the structural design with a licensed engineer, and we schedule the noisy phases, like floor framing and shear wall installation, around your family’s routine rather than through it.
Working Within Burbank’s Height and Setback Rules
Burbank’s planning department enforces specific height limits and setback requirements that vary by zone. We pull the parcel data and confirm what’s buildable before we quote, so you’re not paying for design work on a second story the city won’t approve. On 1950s ranches inside the airport noise contour, upper-level windows need STC-rated glazing, which changes the budget, and we tell you that up front.

Trusted Brands We Service in Burbank
Seedling works hands-on with prefab and modular brands Burbank buyers already research: Abodu, Cover, and Dvele are three we source for clients who want factory-built precision. Because we stock parts and coordinate directly with these manufacturers for Burbank jobs, custom orders don’t sit in limbo. Whether you’re adding a modular studio or a stick-built primary suite, you’ll get a written price before any work starts and the same 365-Day Done Right Promise when the job is finished.
Common Home Addition Contractor Problems We See in Burbank Homes
- Original 60-amp or 100-amp electrical service. Burbank’s 1940s and 1950s homes were built for cloth-wrapped wiring and a few appliances. Adding a bedroom with a mini-split, outlets, and lighting almost always triggers a panel upgrade to 200 amps, and code requires it before the new space can be energized.
- Knob-and-tube branch wiring hidden behind walls. Homes in Magnolia Park and the blocks south of Olive Avenue frequently still have live knob-and-tube circuits feeding outlets and lights. Once a wall is open and the inspector sees it, it has to come out. We’ve learned to expect this and write an allowance for it into the contract.
- Failed waterproofing around old bathroom additions. Decades of slow leaks rot sill plates and rim joists behind tile that looks fine from the outside. The rot doesn’t announce itself until the wall is open, and then it has to be reframed before anything new goes over it.
- Airport noise-contour requirements missed at the quoting stage. Contractors who don’t work Burbank regularly quote additions without checking the ALUCP map. Then the plans come back from plan check needing STC-rated windows, upgraded wall assemblies, and mechanical ventilation that weren’t in the budget. We pull the map before we quote, every time.

FAQs About Home Addition Contractor in Burbank
A Burbank addition usually carries extra cost because of the Hollywood Burbank Airport ALUCP noise-contour requirement. Parcels inside the 65 dB CNEL zone must build every new habitable room with STC-rated glazing, upgraded exterior wall assemblies, and mechanical ventilation, and that adds $8,000 to $20,000 to a typical room addition. Glendale parcels outside any airport overlay never face that spec. Labor and materials are otherwise similar across the two cities. Call (707) 383-5338 and we’ll check whether your parcel falls inside the contour before we quote.
It doesn’t kill it, but it does change the scope and the price. A 60-amp or 100-amp panel can’t safely feed a new bedroom, bathroom, or second story, and when the walls are open, Burbank’s inspectors will require the panel upgrade and removal of any knob-and-tube wiring they can see. A 200-amp panel upgrade in Burbank runs roughly $4,000 to $8,000. We write that allowance into the contract up front so it’s priced, not a surprise. Call (707) 383-5338 for an exact quote on your home.
We stop, document what we found with photos, and price the repair as a written change order you approve before we touch another board. No hidden work, no verbal agreements.
On a 1947 Magnolia Park ranch where we opened the back wall for a primary-suite addition, the demolition exposed cloth-wrapped knob-and-tube wiring feeding the original 60-amp service, plus a bathroom floor that had been leaking into the framing for years. The sill plates were soft and the rim joist behind the tile was blackened. We documented the rot and wiring, priced the panel upgrade, the reframe, and new waterproofing as a written change order, got the homeowner’s approval, then rebuilt the wall to the airport sound-attenuation spec with upgraded glazing. That’s how we work every time. Call (707) 383-5338 to schedule a free estimate.
Yes. Most 1950s Burbank ranches can support a second story, but the first-floor structure usually needs reinforcement first. Footings and walls built for a single story often require engineered upgrades before the upper floor goes on. We handle that engineering and permitting as part of the project, and we’ll tell you during the estimate whether your specific home is a good candidate. Call (707) 383-5338 to schedule a free estimate.
Yes, and that’s true across California. Pulling a permit for an addition triggers current code requirements for the existing electrical system, insulation, smoke and carbon monoxide detectors, and often the water heater strapping. On older Burbank homes, the electrical panel and knob-and-tube wiring are the two big ones. We build these upgrades into the written allowance schedule before work starts, so the permit doesn’t turn into a fight mid-project. Call (707) 383-5338 and we’ll walk you through what your specific home will require.
