Fast, Reliable Home Addition Contractor Across Artesia
If you’re planning a home addition in Artesia, you’re likely looking at a project that runs anywhere from $85,000 for a modest bump-out to $240,000+ for a full second-story addition, with most single-story room additions landing between $110,000 and $165,000. Those are real numbers for this market, and they include the code upgrades older Artesia homes nearly always require. We’re Lodgewick ADU Builders, and we’ve spent years working on the 1950s and 1960s ranch homes that dominate this city’s residential streets. When you call (254) 602-5618, you’ll get a straight answer about what your addition will actually cost, not a vague “we’ll see when we open the walls.”
Our crews know Artesia specifically: the post-WWII housing stock south of 91, the tight 5,000 to 7,500 square foot lots, the full streets around Pioneer Boulevard, and the city’s small but surprisingly efficient building department. That local knowledge matters when it comes to pricing a job accurately the first time.
Why Lodgewick ADU Builders Is Artesia’s Preferred Home Addition Contractor Company
Homeowners in Artesia call us because we put every commitment in writing before work begins. That’s The Kingswell Way, and it’s been how we operate since 2010, led by Russ Delmar and the Kingswell family of home-service companies. Before a single nail is driven, you get a written price, a defined arrival window, and a written guarantee. If the work isn’t right within 365 days, we come back and make it right. That’s the 365-Day Done Right Promise, named in writing on every project.
We’ve earned a strong local reputation in Artesia by showing up when we say we will, keeping job sites clean, and answering the phone. A live person answers every call, 24 hours a day, seven days a week. No voicemail loops, no chatbot. When you have a question about your build or your guarantee, you talk to a person who can actually help. Our background-checked, uniformed technicians arrive on schedule, and you’ll always know who’s on your property.
Our familiarity with Artesia’s housing stock means we plan for what’s behind the drywall: cloth-wrapped wiring, undersized headers, and 100-amp electrical panels that need upgrading before an addition can pass inspection. We write those costs into the contract upfront so your quote doesn’t move when demolition day reveals what we already expected to find.
Garage Addition Contractors in Artesia
Garage Addition Contractors in Artesia work primarily on the attached and detached single-car garages that came standard on the 1950s through early 1970s ranch homes filling this city’s residential blocks. A garage addition in Artesia typically converts that underused space into a family-occupancy ADU or a connected living area, and it runs $70,000 to $140,000 depending on whether you’re adding a full kitchen, a bathroom, or a private entrance. Most Artesia homeowners pursue this as an in-law suite for aging parents or adult children rather than a rental unit, which changes the design priorities significantly.
What the conversion actually involves
On most Artesia lots, the garage slab lacks a vapor barrier, which means we’re either sealing it properly or pouring a new slab before flooring goes in. The existing garage door opening usually has an undersized header for the added load of a new exterior wall with a window or French door. And the electrical panel feeding the garage is almost always the same 100-amp service running the whole house. We handle all of it: 200-amp upgrade, header re-framing to plan, and waterproofing done right the first time.
Planning for the permit process
Artesia’s building department processes ADU permits faster than LA City, but the staff is small. A single plan-check correction means your project waits in line again. We submit garage-conversion drawings complete on the first pass: structural, electrical, plumbing, and title-24 energy all properly documented. That’s how we keep your Artesia project moving instead of stalling in revision cycles.
Bathroom Addition Contractor in Artesia
A Bathroom Addition Contractor in Artesia needs to plan for the hard municipal water that shortens the life of fixtures and water heaters in this city’s homes. Adding a full bathroom to a 1950s Artesia ranch typically runs $35,000 to $65,000, depending on whether it’s a compact 3/4 bath off a hallway or a larger attached bathroom serving a new primary suite. Older Artesia homes often need drain-line re-routing and, frequently, a 200-amp panel upgrade if the addition adds any electrical load to the existing service.
Bathroom additions on tight Artesia lots
Most Artesia homes sit on modest lots where a bathroom addition means going up or bumping out rather than adding a full new wing. We design bump-out additions that capture unused side-yard space, which is common here given the oblong lot shapes in the neighborhoods east and west of Pioneer Boulevard. The flat terrain and mild winters mean no frost-line complications, but we do plan for Artesia’s hard water by recommending fixtures and water-heater placement that handle sediment buildup better over time.
JADUs and small-footprint additions
A bathroom addition often pairs with a JADU, or junior accessory dwelling unit, which in plain English is a smaller, attached living unit with its own bath and a kitchenette. In Artesia, where multigenerational households are the norm, a JADU with a private bathroom is frequently the fastest path to giving an adult child or a grandparent their own livable space without the footprint of a full ADU.
Trusted Brands We Service in Artesia
We work directly with established prefab ADU manufacturers including Cover, Dvele, and Boxabl, which means Artesia homeowners can choose a factory-built addition when the site and timeline favor it over a traditional stick-built project. These systems arrive with precision engineering and consistent quality, and they can cut months off a build compared to framing on site. Because our crews are familiar with each manufacturer’s installation requirements, we handle the foundation work, utility connections, and finish-out without surprises. We also work extensively with James Hardie siding products for stick-built additions, particularly on Artesia homes where matching existing 1950s and 1960s exterior materials matters to the finished look.
Common Home Addition Contractor Problems We See in Artesia Homes
- Cloth-wrapped wiring behind the drywall. Many Artesia ranch homes still have original 1950s-era cloth-insulated electrical wiring. It’s a fire hazard once walls are open, and it has to go before an addition can be safely connected. We budget for rewiring when the existing panel and branch circuits predate the 1980s.
- 100-amp panels feeding the whole house. Add a kitchen, a bathroom, or any significant electrical load to a 100-amp service and you’ll need a 200-amp upgrade. Artesia homeowners who get quotes that ignore this are looking at a price change later. We include it upfront.
- Undersized headers over garage door openings and old window openings. When a 1950s framing crew installed a header, they sized it for the load they were building then. Adding a second-story or bump-out changes the load path. We re-frame to plan, not to code minimum.
- Failed waterproofing at the slab and foundation perimeter. Artesia’s flat basin geography means poor drainage around older foundations is common. We address hydrostatic pressure issues and install proper vapor barriers before any flooring or wall finish goes in.

FAQs About Home Addition Contractor in Artesia
Because the quote didn’t account for what’s actually behind the drywall. A 1950s Artesia ranch nearly always has cloth-wrapped wiring, a 100-amp panel, undersized headers, and slab waterproofing issues that a thorough inspection would have caught on day one. The honest number is higher than the attractive number, and we give you the honest number before you sign. Call (254) 602-5618 for an estimate that includes the code upgrades.
Yes, in most cases. Artesia’s small lots and older garages make this the city’s most common ADU conversion target. The work involves upgrading the electrical service, re-framing the old door opening, addressing the lack of a vapor barrier under the slab, and adding a proper private entrance. We handle the full conversion including a full kitchen and bath when the homeowners want a self-contained in-law suite.
Artesia’s building department is small and moves applications faster than LA City’s, largely because the city is only 1.6 square miles and processes a smaller workload. The catch is that a single plan-check correction goes back into the queue with everything else. We submit complete, code-compliant drawings on the first pass so your permit doesn’t stall in revision cycles. That’s an information edge homeowners don’t get with a contractor who files incomplete plans.
If your home still runs on a 100-amp panel, yes, almost always. Adding a kitchen, bathroom, laundry, or an ADU with a water heater pushes past what a 100-amp service can safely handle. The upgrade to 200 amps adds $4,000 to $7,000 to the project, and it’s in our written estimate before work starts, not a surprise discovered mid-build.
A private entrance, a full kitchen, a full bathroom, and its own climate control. In Artesia, where multigenerational living along the Pioneer Boulevard corridor is a cultural norm, in-law suite ADUs are designed for family occupancy, not rental income. That means a real kitchen, not a kitchenette, and a bathroom with enough clearance for aging parents. We design to those needs from the first drawing. Call (254) 602-5618 to talk through your lot and your family’s needs.
