Adding square footage to a Lakewood home means working with houses built between 1940 and 1960, and that changes everything about how a job should be priced and planned. We’re Sutton ADU Long Beach, and we’ve spent years opening up these mid-century stucco homes across Lakewood, learning what’s behind the walls before we ever put a number in front of you. A bedroom addition in Lakewood typically runs $140,000 – $240,000 depending on scope, and a sunroom addition usually lands between $65,000 and $135,000. If you’re thinking about adding space, call Home Addition Contractor team at (562) 317-7042 for a free estimate, and we’ll walk your lot the way an inspector would.
Why Sutton ADU Long Beach Is Lakewood’s Preferred Home Addition Contractor Company
Lakewood homeowners call us because we treat their 1950s ranch or 1940s bungalow like the specific structure it is, not a blank lot. The housing stock near Mayfair Park, around Del Valle Park, and along the Carson Street corridor is remarkably consistent: wood-framed, stucco-clad, single-story, with garages that were built before modern seismic codes existed. That consistency is useful, because it means we’ve seen the same failure patterns enough times to price them honestly up front. We document everything before demo day. Our Threshold Verified crew standard means every technician who steps onto your Lakewood property is background-checked, identity-verified, uniformed, and photo-badged, with their name and photo sent to you before arrival. You’ll know exactly who is opening your front door.
We also know Lakewood’s permit office expectations, from the setback requirements off your rear property line to the aesthetic review standards that apply when your front-facing elevation changes. That local fluency saves you weeks of back-and-forth. And our Lakewood customers consistently tell us the same thing: the written price we delivered before work started is what they paid at the end. No change order silence, no scope creep passed quietly to the bill. That’s the Threshold Standard in practice.
Bedroom Addition Contractor in Lakewood
A Bedroom Addition Contractor in Lakewood is dealing with something builders in newer developments don’t face: original 1940s – 1950s framing that often doesn’t meet current lateral load requirements, electrical systems that were never designed for a modern bedroom, and slab footings that may not extend deep enough for the added load. In Lakewood, a bedroom addition typically costs $140,000 – $240,000, with the range driven by whether you’re adding onto the back of the house or bumping out a side wall, and by what the opening-up phase reveals.
Footing Depth and Foundation Verification
Many of these 1950s Lakewood garages and rear additions sit on slabs with footing depths that worked fine for a garage but fall short for habitable space. We don’t assume. We verify the footing before designing the addition, because retrofitting a foundation after the walls are framed doubles the cost and delays the job by weeks. If your addition touches an existing slab, we include a discovery-phase allowance in the written contract.
Electrical and Seismic Code Triggers
Adding a bedroom means adding an egress window, hardwired smoke detection, and often an AFCI circuit or two. It can also trigger seismic bracing requirements on the original cripple walls. In Lakewood, local inspectors consistently flag these on original houses. We plan for them in the initial quote, so the number you sign is the number that holds.
Sunroom Addition in Lakewood
A Sunroom Addition in Lakewood gives you the daylight of Southern California living without the full structural cost of a conventional room addition. Most sunrooms we build in Lakewood run $65,000 – $135,000, depending on whether you want a three-season room with single-glazed windows or a four-season space with insulated glass and its own mini-split. The mild Mediterranean climate here means a well-ventilated sunroom stays comfortable most of the year, but the wet winters make moisture management the most important detail.
Ventilation for Wet Winters
Lakewood’s rainy season runs November through March, and a sunroom built without proper ridge and soffit venting turns into a humidity trap. We spec continuous ventilation on every Lakewood sunroom, even the three-season ones. The extra cost is minimal. The mildew prevention is real.
Foundation Options for Sunrooms
On a 5,000 to 7,000 square foot Lakewood lot, a sunroom usually goes on a pier-and-beam or a thickened-edge slab. Pier foundations disturb less of your existing yard and cost less to permit. Slab foundations feel more rooted and allow a flush floor line into the existing house. We’ll price both.
Trusted Brands We Service in Lakewood
We’re fluent with the product lines that make sense for Lakewood’s lot patterns and mid-century housing stock. For garage-to-ADU conversions, we work with Tuff Shed structures and Abodu prefab units, both of which handle Lakewood’s compact rear yards well. For exterior cladding on additions and full remodels, we specify James Hardie systems because they hold paint better than stucco alone and stand up to the coastal moisture that moves inland toward Lakewood. We keep local inventory access so parts and panels don’t stall your job waiting on a distributor.
Common Home Addition Contractor Problems We See in Lakewood Homes
- Knob-and-tube wiring behind drywall. Original 1940s electrical systems often hide behind decades of patches. You can’t see it until the wall is open, and replacing it is a five-figure line item if it wasn’t planned for.
- Notched or undersized headers over garage openings. A 1950s garage door header was sized for a garage door, not for a bedroom above it. We regularly find headers notched to unsafe depths when a previous owner ran plumbing or ducting through them.
- Footing depth that fails current code. Garage slabs and older patio slabs in Lakewood frequently sit on footings too shallow for habitable space. Discovery before framing is cheap. Discovery after framing is not.
- Failed waterproofing behind original stucco. The stucco itself holds up fine. The flashing and paper behind it often doesn’t, especially on west-facing walls that take the winter rain off the coast. If you’re tying into an existing exterior wall, we check it before we commit to it.

It means we open the relevant walls or access the crawl space and subfloor before we finalize your number. We’re looking at wiring type, framing condition, footing depth, and waterproofing. That inspection shapes your written price so the quote doesn’t move after demo day. Call (562) 317-7042 to schedule yours.
On a quiet street near Mayfair Park, our crew opened up a 1954 stucco home for a bedroom addition and found original knob-and-tube wiring spliced into Romex, a header over the garage door that had been notched to 40% of its required width, and failed waterproofing behind the existing stucco. We documented every deficiency, wrote the allowance-driven change order, and the homeowner signed off before we reframed, rewired, and flashed the new addition to current code. That’s how we work in Lakewood: document first, price second, build third.
