AfterFast, Reliable Home Additions & ADU Across Burbank
Home additions and ADU construction in Burbank typically run $45,000-$130,000 for room additions and $90,000-$220,000 for detached units, with most projects requiring 4-8 months from permit to final inspection. Rowan Construction Group coordinates scheduling from our Los Angeles office and dispatches crews to Burbank daily. We’ve worked the 1940s-1960s ranch grids from Magnolia Park to the Rancho district long enough to know what those plaster-and-lath walls hide, and we write the price for it before anyone picks up a hammer. Call (213) 221-0788 to schedule your free estimate.
Why Rowan Construction Group Sherman Oaks Is Burbank’s Preferred Home Additions & ADU Company
We’ve delivered home additions and ADUs across Burbank since before the 2019 state ADU laws reshaped the market. Our crews know the difference between a Burbank Community Development Department inspection and LADBS - because they’re entirely separate systems, and treating them the same is how projects stall.
Burbank homeowners leave reviews that mention the same thing: the written price held. Our 365-Day Done Right Promise is printed on every contract, backed by The Haven Standard terms page, not an asterisk. Under Clause 1, the price is written before any work starts - always.
Calls route to a live person 24/7. Crews arrive background-checked and uniformed. Every visit generates a documented photo record, included standard, so you see what we found and what we did.
Our free Second Opinion on Any Written Estimate means you can bring a competitor’s Burbank quote and we’ll review it line by line at no charge.
Our Home Additions & ADU Services in Burbank
Room Additions
Most Burbank room additions we build extend 1940s-1960s ranch footprints in Magnolia Park, the Rancho area, or the hillside streets below the Verdugo Mountains. The framing connects to original cripple-wall foundations that Burbank inspectors specifically flag for seismic deficiency - a local enforcement emphasis that out-of-area contractors regularly miss. We inspect before we frame, write structural allowances into the contract, and price any cripple-wall upgrade as a formal change order signed before work proceeds. A typical Burbank room addition runs $45,000-$130,000.
Garage Conversion ADU
Garage conversions in Burbank face a specific hurdle: many original garages sit on slabs poured without the stem-wall depth required for habitable space under current Burbank code. We assess the existing foundation, calculate the upgrade if needed, and put that number in writing before demolition starts. The city’s Community Development Department - not LADBS - issues the permit and conducts inspections, so our general contractor maintains the compliance relationship directly with Burbank staff. A garage conversion ADU in Burbank typically costs $30,000-$80,000.
New Detached ADU
Detached ADUs in Burbank must account for the city’s compressed Santa Ana wind corridor between the Verdugo Mountains and the valley floor. Ember transport risk runs higher here even on non-WUI parcels, so exterior finish material choices - decking, roofing, soffits - face heightened fire-resistance scrutiny from Burbank inspectors. We specify IKO or Atlas roofing assemblies rated for the exposure, and we document the spec in the written quote so there’s no substitution at the lumber yard. A new detached ADU in Burbank runs $90,000-$220,000.
Junior ADU & Interior Conversion
Junior ADUs work well in Burbank’s smaller 1940s bungalows where a full detached unit won’t fit the lot coverage. These conversions share walls with the primary residence, which means the original electrical panel and service entrance often need upgrading once walls open. We pull the permit history before we quote, check the existing service size, and write the electrical allowance into the contract - not as a surprise later.

AfterTrusted Brands We Service in Burbank
Rowan sources across fifty-plus vetted brands, and we stock assemblies locally for Burbank jobs. For roofing on detached ADUs in the wind corridor, we specify IKO or Atlas shingles with the fire ratings Burbank inspectors expect. Where the original home needs re-roofing as part of a second-story addition, we match with Tamko or Boral components rated for the exposure. The brands are named in your written quote, not swapped at the supplier’s convenience.
Common Home Additions & ADU Problems We See in Burbank Homes
- Ungrounded electrical behind plaster-and-lath. Opening a 1948 Magnolia Park ranch wall regularly reveals knob-and-tube or early Romex cloth wiring that fails current Burbank electrical code the moment the addition triggers a full rough-in inspection. We scope the panel and service entrance before we quote, and we write the electrical upgrade as a line-item allowance.
- Cripple-wall seismic triggers. Burbank’s Community Development Department enforces seismic retrofitting on cripple-wall foundations in the Rancho and Magnolia Park areas because the Verdugo Fault runs through the city’s north side. We inspect the foundation before framing, price the retrofit in writing if needed, and schedule the seismic inspection before we close any walls.
- Failed waterproofing at old thresholds. Room additions that tie into original Burbank ranch slabs often find the old door threshold membrane has rotted through. The repair isn’t visible until demolition, so we include a waterproofing allowance in every addition contract tied to pre-1970s construction.
- Foundation depth shortfalls on garage conversions. Original Burbank garage slabs frequently lack the 18-inch stem-wall depth required for habitable space. We probe the slab edge during our initial site visit and price the stem-wall extension or replacement as a signed change order before concrete work starts.

FAQs - Home Additions & ADU in Burbank
Yes, if your home has a cripple-wall foundation and sits in the Magnolia Park or Rancho areas where Burbank actively enforces seismic deficiency corrections. We inspect the foundation during our site visit, write a structural allowance into the contract, and price any retrofit as a formal change order before framing begins. Call (213) 221-0788 and we’ll check your foundation type at no charge.
Burbank’s Community Development Department processes all permits entirely separately from LADBS. Our general contractor maintains a direct compliance relationship with Burbank inspectors, not LA City. This distinction matters - out-of-area contractors who submit to the wrong jurisdiction lose weeks. We file with Burbank directly on every job.
Ungrounded knob-and-tube or early Romex cloth wiring, failed waterproofing at original thresholds, and cripple-wall foundations that trigger mandatory seismic retrofitting. In a 1948 Magnolia Park ranch, our crew found exactly this combination - ungrounded cloth wiring and a cripple-wall foundation the homeowner had never heard of. Because we had scheduled the Burbank inspection before framing and written a structural allowance into the contract, we priced the cripple-wall upgrade as a signed change order with no surprises. The inspector signed off on rough-in and retrofit before we closed a wall.
No work proceeds on a change until the change order is signed. This is Clause 1 of The Haven Standard. We document the condition with photos, write the scope and price, and get your signature before we touch it. The administrative discipline Haven acquired Rowan for - and the reason projects finish within a few percent of the agreed price.
Yes, with fire-resistant exterior assemblies specified for the exposure. Burbank sits in a compressed Santa Ana wind corridor that accelerates ember transport, so inspectors scrutinize roofing, decking, and soffit materials even on non-WUI parcels. We specify IKO or Atlas roofing rated for the condition and document the exact assembly in your written quote. Call (213) 221-0788 to review the spec for your lot.
