Most home additions in Burbank run $220 – $410 per square foot for standard stick-frame construction, before design and permit fees. A simple bump-out addition of 250 square feet typically lands between $55,000 and $105,000, while a full second-story addition on a typical Magnolia Park bungalow starts around $180,000 and can exceed $350,000 depending on structural work. Those numbers come from real projects we’ve scoped in Burbank’s existing housing stock, not national averages. If you’re weighing whether your lot can even accommodate the addition you want, call us at (472) 248-8213 and we’ll walk you through the math before you spend a dollar on drawings.
Burbank’s single-family neighborhoods sit under some of the tightest lot-coverage and rear-yard setback math in the Verdugo corridor. A home addition here is usually a massing puzzle before it’s a construction project. What fits behind the house is dictated by Burbank Municipal Code limits on lot coverage and required rear setbacks, not by how much square footage the homeowner wants. In neighborhoods like Magnolia Park, the Rancho District, and the streets around Johnny Carson Park, many 1940s and 1950s homes already exceed today’s coverage thresholds, which means an addition often requires converting existing footprint rather than expanding outward. Getting that scoped correctly on day one is the difference between a smooth plan check and a red-tagged drawing set.
Why Sutton ADU Builders Is Burbank’s Preferred Home Addition Contractor Company
We’ve done this work in Burbank long enough to know which blocks trigger neighborhood design review and which lots can carry a bump-out without a variance. Burbank homeowners call us because our Home Addition Contractor team shows up with a written price before any work starts, and because every person we send to a property is background-checked, identity-verified, and photo-badged under the Threshold Verified standard. You’ll know the name and face of the person walking up your driveway before they arrive. That matters in Burbank, where homeowners often have young kids, an aging parent at home, or a work-from-home schedule that makes unannounced strangers a real problem.
Miles Hartwell leads the team, and he’s built the Burbank operation around one principle: nobody should open their front door to an unvetted construction crew. The 365-Day Done Right Promise backs every project we complete in Burbank. If the work isn’t right within a full calendar year, we make it right. Written guarantee, stamped on the contract. We also provide a free second visit if any element of the build fails. No haggling, no invoice. That’s the Threshold Standard applied to every Home Addition Contractor in Burbank project we take on.
Garage Addition Contractors in Burbank
Garage Addition Contractors in Burbank handle a specific job: extending or expanding an existing garage into conditioned living space, or adding a second story above a garage when the lot can carry it. This is one of the most requested scopes in Burbank because so many homes here have detached garages on alleys off streets like Chandler Boulevard and Verdugo Avenue, where a rear-lot addition doesn’t touch the main house’s footprint. A garage addition in Burbank typically runs $190 – $280 per square foot for standard finishes, with the final number driven by whether we’re converting existing space or building new. If you’re adding plumbing and a bathroom above a detached garage in the Rancho District, expect total costs to start around $120,000 and climb from there.
Converting vs. Building New
Converting an existing Burbank garage into living space usually costs less per square foot than building new walls, because the shell already exists. But don’t assume a conversion is automatically cheaper. Many older Burbank garages have slab foundations that fail current seismic and structural standards, which means we’re often pouring new footings and reinforcing the slab before any framing touches the walls. That work alone can add $15,000 to $30,000 to a project budget.
Second-Story Garage Additions
If your Burbank lot is maxed out on coverage, going up is often the only path. A second story above a garage requires structural evaluation of the existing framing, and in many Burbank homes built before 1960, the garage walls aren’t engineered to carry a second floor. We budget for steel beams or a full reframe in these cases. A second-story garage addition in Burbank with a small bathroom starts around $160,000 and often lands closer to $240,000 when structural upgrades are required.
Bathroom Addition Contractor in Burbank
A Bathroom Addition Contractor in Burbank handles a project that looks small on paper but touches every system in the house: plumbing, electrical, ventilation, waterproofing, and often a sewer-line connection that hasn’t been touched since the home was built. Burbank homes from the 1930s through the 1950s, especially in the Magnolia Park and Rancho areas, often have cast-iron drain lines that need replacement or relining before a new bathroom can pass inspection. A standard 5×8 bathroom addition in Burbank runs $45,000 – $75,000 depending on finishes, and that range assumes existing supply and drain lines are in usable condition. If we’re tying into an old cast-iron stack, add $8,000 – $15,000 for replacement work.
Where the Bathroom Goes Matters
Burbank lot coverage limits mean many bathroom additions go inside the existing footprint, often carved from a porch, a hallway, or a section of an oversized living room. That’s fine. But if the new bathroom extends past the current exterior wall, we’re now talking about a bump-out, which triggers setback reviews and possibly neighborhood design review depending on your street. The placement decision drives the price more than any finish selection.
Ventilation and Title 24
Every new bathroom in Burbank must meet California Title 24 energy and ventilation standards. That means a dedicated exhaust fan on a timer or humidity sensor, LED lighting, and in many cases a new dedicated circuit. It’s not optional, and it’s not a negotiation with the city. We budget it into every bathroom addition quote from day one, so the price you see is the price you pay.
Trusted Brands We Service in Burbank
We work with a handful of ADU and addition product lines that make sense for Burbank lots: Abodu for compact one-bedroom units, Cover for precision-engineered wall panels that speed up framing, and Dvele for homeowners who want a higher-efficiency envelope. We also handle Tuff Shed conversions when a homeowner already has a permitted shed and wants to turn it into livable space. We stock the hardware and finishing components our Burbank projects need locally, so a missing bracket or flashing detail doesn’t stall a framing crew for three days. We’ll tell you honestly which product line fits your lot, your budget, and your timeline, and which ones don’t.
Common Home Addition Contractor Problems We See in Burbank Homes
- Designing before checking lot coverage. We regularly see plans from homeowners who’ve already paid an architect for a 400-square-foot addition on a lot that can only legally carry 120 more. In Burbank, remaining lot-coverage allowance is the ceiling, not the starting point, and redrawn plans cost real money.
- Older slabs and foundations. Homes in Magnolia Park and the streets north of Olive Avenue often sit on unreinforced or minimally reinforced slabs. A bump-out addition frequently triggers a foundation upgrade on the existing structure, not just the new footprint. Budget for it before you start.
- Cast-iron drain lines. Burbank homes built before 1960 commonly have original cast-iron sewer lines under the house. Adding a bathroom or wet bar means tying into lines that may be corroded or cracked, and city inspectors won’t sign off on a connection to a failing line.
- Garage conversions mistaken for ADUs. Burbank’s ADU ordinance doesn’t automatically cover a non-ADU garage conversion or addition. Different permit path, different fees, different inspections. We’ve seen projects stall for months because the scope was filed under the wrong permit type.

FAQs About Home Addition Contractor in Burbank
No. A home addition in Burbank is permitted as new construction under the city’s standard building code path, not under the ADU ordinance. That means separate structural review, Title 24 energy compliance, and in some neighborhoods a design review process that doesn’t apply to ADU projects. We scope each project against the correct permit path before drawings begin, so you don’t get a plan-check surprise. Call (472) 248-8213 and we’ll check your property’s zoning before you spend on design work.
A typical Burbank home addition takes 4 to 7 months from first call to final inspection. The variables are plan check duration at the city, which currently runs 6 to 10 weeks for additions, and whether your project triggers neighborhood design review. Construction itself for a single-room bump-out usually runs 8 to 12 weeks once permits are issued. We’ll give you a written schedule at the estimate, and we update it as the permit process moves. Call (472) 248-8213 to start with a site visit.
The three things that change price on a Burbank project are foundation conditions discovered after demo, drain-line age and condition, and electrical panel capacity. None of these are visible until walls are open or trenches are dug. That’s why we do a full foundation and plumbing scope before quoting, and why our written price is line-item so you can see exactly what’s included. We don’t pass change orders silently into the bill. If we find something, we stop and show you before spending your money.
Yes, in many cases converting or extending a garage is the most cost-effective way to add square footage on a Burbank lot. The existing structure already counts against your lot coverage, so converting it often means adding zero new coverage. Extension works when the garage sits on a slab that can carry the load and when the lot has rear-yard space to give. We’ve done garage conversions throughout the Rancho District and Magnolia Park, and we’ll tell you honestly if your garage is a conversion candidate or a tear-down. Call (472) 248-8213 for a free assessment.
Yes. Any new conditioned square footage in Burbank triggers California Title 24 compliance, which covers insulation, window performance, HVAC efficiency, lighting, and ventilation. A home addition is new construction under the energy code, not a remodel exemption. We build Title 24 compliance into every Burbank quote, including the HERS testing and documentation. No surprise line item at the end.
