Home Addition Contractor in Maywood - Design, Permits and Build Under One Contract

Fast, Reliable Home Addition Contractor Across Maywood

A room addition in Maywood typically runs $140 – $260 per square foot for a standard build, with most garage conversions landing between $95,000 and $185,000 all-in. The real wildcard on this side of Los Angeles County isn’t labor or lumber; it’s what’s hiding inside your 1920s – 1950s walls. We’re Lodgewick ADU Builders, the ADU and addition company of the Kingswell family, and we’ve spent years opening up Maywood bungalows that had galvanized pipes weeping, cloth-wrapped wiring, and 100-amp panels with no room left. If you’re thinking about a sunroom addition, room addition contractor work, or a garage conversion off the alley, call (254) 602-5618 and we’ll walk you through what your specific lot will actually allow.

Why Lodgewick ADU Builders Is Maywood’s Preferred Home Addition Contractor Company

Maywood is dense. At roughly 1.18 square miles with most lots running under 5,000 square feet, there’s no room for a contractor who guesses. We’ve worked the alley grid behind Slauson, Atlantic, and the residential blocks off 52nd and 54th, and we know what the city’s plan-check process flags before we ever write a contract. That’s the point of our inspection-first method: we open the wall or pull the panel cover before you sign, so the number we put in writing is the number the job costs. Russ Delmar, who leads our Maywood work, has walked enough of these 1920s – 1950s bungalows to tell you within fifteen minutes whether your addition needs a panel upgrade, a repipe stub, or a drainage detail at the rear entry.

Every Lodgewick project runs under The Kingswell Guarantee. That means a written price before work starts, a defined arrival window, a clean job site, and a written guarantee on every project, including a free return visit if anything fails within the 365-Day Done Right Promise. A live person answers our phone 24/7, not a voicemail, because when you’re mid-build and a question comes up at 7 a.m. before the crew arrives, you should get an answer. Maywood homeowners tell us the same thing: the price staying written is the reason they call us instead of whoever quoted them last time.

Sunroom Addition in Maywood

A sunroom addition in Maywood runs $38,000 – $72,000 for a typical 150 – 220 square foot build, depending on whether you’re doing a three-season room or a fully conditioned four-season space. On Maywood’s tight lots, sunrooms usually attach to the rear of the house facing the alley, which keeps the street facade intact and works within the side-yard setbacks that squeeze almost every parcel here. The biggest cost driver we see is HVAC: Maywood sits far enough inland that summer afternoons run noticeably hotter than westside LA, so a three-season room with no cooling becomes unusable by July. Most Maywood homeowners end up adding a ductless mini-split, and that often requires the panel upgrade we discuss below.

Three-Season vs. Four-Season

A three-season sunroom keeps costs down and works if you’ll use the space spring through fall. A four-season room with insulation, a mini-split, and proper glazing costs more upfront but gives you an actual living room, dining nook, or home office year-round. In Maywood, we usually recommend four-season: these bungalows are small, and the square footage matters most when the kids are home and the house is full.

Alley-Side Drainage and Access

Because Maywood’s sunrooms almost always face the alley, the rear entry needs to be flashed and sloped correctly or you’ll pond water at the door every winter rain. We detail this to the city’s drainage standard before we frame, and it’s one of the things Maywood’s contracted plan-check consistently reviews.

Room Addition Contractor in Maywood

A full room addition in Maywood runs $55,000 – $140,000 for a 200 – 400 square foot bedroom, den, or expanded kitchen, and most homeowners here are actually better served by a garage conversion or rear bump-out than a traditional stick-built addition. The reason is the lot itself: with sub-5,000 square foot parcels and rear alleys taking up the back half of most blocks, there’s rarely room to add a 400 square foot conventional wing. California’s post-2020 ADU preemption laws, which override local setback and lot-coverage limits, are what make most Maywood additions possible at all, because without that state override almost every parcel here would be flatly ineligible.

Garage Conversion as the Maywood Default

Your detached garage, mostly 200 – 300 square feet, accessed from the alley, is usually the smartest path to more living space. We convert it, run utilities from the main house, upgrade the panel, and you get a permitted dwelling unit without eating into the yard your kids actually use. This is the most common Home Addition Contractor project we build in Maywood, and it’s most of what the local code path is written around.

Bump-Outs and Small Rear Additions

When a garage conversion isn’t enough, a rear bump-out of 100 – 200 square feet works within most Maywood setbacks, especially when we tie it into the existing roofline. We frame, flash, and waterproof to match the original bungalow profile so it reads like the house always had that space.

Trusted Brands We Service in Maywood

We work hands-on with prefab and panelized manufacturers including Cover, Dvele, and Boxabl, matching each to your Maywood lot, budget, and timeline. Cover and Dvele make sense for homeowners who want design-forward, highly insulated units that go up fast on a tight alley lot. Boxabl fits when you need a small unit on a postage-stamp parcel and want the shell delivered and set in a day. Because we coordinate with these manufacturers directly, we can order factory-built components for Maywood jobs and hold them until the site is ready, which keeps scheduling predictable on lots where a crane or delivery truck needs alley coordination.

Common Home Addition Contractor Problems We See in Maywood Homes

• Galvanized supply lines that fail the moment you open the wall. In 1940s – 1950s Maywood construction, original galvanized plumbing is often already weeping at the threaded joints. When we extend plumbing to a converted garage or new room, those lines frequently need replacement, and that’s a cost you want in the contract, not discovered at inspection.
• 100-amp or smaller electrical panels. Most Maywood bungalows were built with fuse boxes or early breaker panels under 100 amps. Adding a room or a mini-split circuit means a panel upgrade, full stop. We check this before we quote so the number we write is the number you pay.
• Cloth-wrapped wiring in exterior walls. We routinely find original cloth-insulated wiring in Maywood homes, and it does not meet current code once the wall cavity is exposed. A permit triggers correction, and we price that allowance into the contract before work starts.
• Alley-side addressing and utility-meter placement. Converted-garage ADUs and rear additions face the alley, not the street. Maywood’s plan-check process, which has historically been contracted out, consistently flags postal addressing, separate utility meter placement, and emergency-vehicle access. We resolve those before framing, not after.
