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

Fast, Reliable Home Addition Contractor Across Long Beach

A home addition in Long Beach typically runs $180 – $420 per square foot depending on scope, site access, and what’s hiding inside your existing walls. We’re Lodgewick ADU Builders, the ADU company of the Kingswell family, and we’ve been building additions, garage conversions, and accessory dwelling units since 2010. When you call (254) 602-5618, a live person answers, not a voicemail loop. That matters when you’re trying to figure out whether a garage addition off a rear alley in Rose Park actually pencils out, or whether a bathroom addition on a 1920s bungalow in Bluff Park will trigger a Coastal Development Permit.

Call (254) 602-5618

Long Beach is its own animal. The housing stock, the zoning, the salt air, the alley grid. A contractor who mostly builds in Lakewood or Signal Hill doesn’t know what we know about how Long Beach Building and Safety processes additions on R-2 lots, or what a 200-square-foot detached garage on a Naples Island property actually needs before it becomes legal living space. Local knowledge isn’t a marketing phrase here. It’s the difference between a permit that sails through and a stop-work order halfway into framing.

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

Long Beach homeowners have dealt with enough contractors who vanish after the deposit or hand over a quote that doubles once the walls are open. The Kingswell Guarantee exists for exactly that reason. Written price before work begins. A defined arrival window. A clean job site. And a 365-Day Done Right Promise in writing on every project. If the work isn’t right, we come back and make it right. No fine print, no phone tag.

Russ Delmar leads our Long Beach addition work, and he’s walked more pre-war bungalows and rear-alley garages than most contractors see in a decade. Our crews show up background-checked and uniformed, so you always know who’s on your property. And every call goes to a live person, 24/7. Not a bot, not a callback queue. When a homeowner in California Heights calls at 9 p.m. with a question about their garage conversion permit, they talk to a human being who can actually answer.

We don’t build additions on speculation. Before anyone swings a hammer, we inspect. On older Long Beach homes, that inspection usually finds something worth knowing about before it becomes an expensive surprise and we write allowances into the contract so every discovery is priced and approved before the work proceeds.

Garage Addition Contractors in Long Beach

Garage Addition Contractors in Long Beach spend most of their time working with detached single-car garages from the 1920s through the 1940s that run 200 to 240 square feet and need more than a fresh coat of paint to become livable. These structures usually require a foundation upgrade, a complete electrical panel replacement, and often a modest bump-out just to clear California’s minimum habitable space threshold. A full garage addition or conversion in Long Beach typically lands between $160,000 and $280,000 depending on whether it’s attached or detached, whether the slab holds up, and whether the alley behind the property is dedicated. That’s a real range, not a teaser number.

The Rear-Alley Garage Reality

Long Beach’s pre-war neighborhoods like Rose Park, Wrigley, and California Heights were built around rear-alley access. That alley grid is an asset if it’s handled correctly. A detached garage addition with a separate rear-alley entrance can get its own postal address, which gives real privacy and stronger rental appeal. But if a contractor frames that new entry door before confirming the alley’s dedication status with Long Beach Public Works, the city can issue a stop-work order mid-project. We confirm dedication status before we frame. Every time.

Foundation and Electrical Upgrades

A 200-square-foot garage in Long Beach was rarely built to modern code. The slab is usually cracked, the framing is undersized, and the electrical service is almost always a 60-amp panel wired with knob-and-tube. Our garage addition estimates include allowances for these upgrades so the written price reflects reality instead of a best-case fantasy.

Bathroom Addition Contractor in Long Beach

Bathroom Addition Contractor work in Long Beach almost always means adding to a 1910s to 1940s bungalow where the floor joists were sized for a clawfoot tub, not a tiled walk-in shower with modern plumbing. A standard bathroom addition in Long Beach typically runs $55,000 to $95,000, and the range widens quickly if the home sits in the Coastal Zone and needs a Coastal Development Permit. The biggest cost driver isn’t tile or fixtures. It’s what’s behind the lath and plaster.

Opening Up Old Walls

When our crew opens a back wall for a bathroom addition on a Rose Park bungalow, we expect to find failed waterproofing, undersized framing, or knob-and-tube wiring. That’s not a reason to panic and it’s not a surprise we spring on you later. We pre-inspect, we write allowances into the contract, and any discovery gets priced and approved in writing before we touch the framing. The written price before work starts is still a written price the day work starts.

Wet Wall in the Coastal Zone

A bathroom addition in Belmont Shore or Naples Island often triggers coastal-zone review, which adds permitting time and changes what materials make sense. Salt-laden air corrodes exposed fasteners and galvanized connectors faster than inland homeowners would believe. We spec stainless fasteners and moisture-resistant materials on every coastal-zone addition because replacing rusted hardware three years after the build is exactly the kind of failure the 365-Day Done Right Promise exists to prevent.

Trusted Brands We Service in Long Beach

We work hands-on with leading ADU brands and materials including Abodu, Cover, and Mighty Buildings, and we stock the components Long Beach projects actually need. That means shorter lead times for prefab panels and faster turnaround when a coastal-zone project needs corrosion-resistant hardware or James Hardie siding. Matching the right system to your lot, your timeline, and the Long Beach permitting reality is what we do before we quote anything. Sometimes a prefab kit is the right call. Sometimes a custom bump-out makes more sense. We’ll tell you which and why.

Common Home Addition Contractor Problems We See in Long Beach Homes

• Knob-and-tube wiring behind the lath. Older Long Beach bungalows still carry the original electrical system, and adding square footage means the panel, the circuits, and often the service drop all need replacement. We inspect before we quote, not after you’ve signed.
• Cracked garage slabs and undersized framing. Those 200 to 240-square-foot detached garages weren’t engineered for living space. Foundation upgrades and structural reframing are common, and we write those allowances into the contract up front.
• Failed waterproofing on rear walls. Long Beach’s marine layer means persistent humidity, and forty years of that against old stucco or wood siding does damage. Once walls are open, we repair what’s there before we build on top of it.
• R-2 zoning surprises. A large share of Long Beach parcels are zoned R-2, meaning some properties were already entitled to a second unit before the 2020 state ADU reforms. That changes the permit path and the fees, and a contractor who doesn’t check zoning before quoting is guessing. We check.
