Adding square footage to a Sun Village home usually costs between $60,000 and $180,000 for a ground-up room addition, while a bathroom addition runs $45,000 to $90,000 and a second-story addition runs $150,000 to $320,000. Those numbers come from local permits, local soil conditions, and the county review process that every Sun Village project has to clear. We’re Benson ADU Builders, and we put every one of those numbers in writing before we pull the first permit. Call (903) 568-7222 for a free estimate and a line-item price you can actually take to the bank.
We know Sun Village because we work here. The unincorporated streets off Pearblossom Highway, the lots south of Avenue S, the older single-story ranches near 20th Street East. When you call, a live person picks up. Not a voicemail loop. Not a call center. Someone who knows what a county plan-check calendar actually looks like and can tell you straight what your addition will face before you spend a dollar on drawings.
Why Benson ADU Builders Is Sun Village’s Preferred Home Addition Contractor Company

We’re part of the Relay Home Co. family, founded in 2006, and our Sun Village work is Home Addition Contractor work done with one rule: a written price before any work starts. That’s The Relay Visibility Guarantee, and it applies to every single project we run in Sun Village. No verbal “probably this much.” No scope creep billed after the fact. The price we show you is the price we build to, and it’s stamped with a 365-Day Done Right Promise: if the work isn’t right within a full year, we make it right, in writing, on every project.
Our Sun Village customers get background-checked, uniformed technicians on every job site. You always know exactly who is walking onto your property. We build with brands you can research yourself: Abodu, Cover, Dvele, and James Hardie cladding. And when you call, someone answers. Around the clock, every day of the year. Troy Eastman, who leads our team, insists on that. A homeowner who can’t get a callback can’t get a straight answer, and in Sun Village, straight answers are the difference between a bid that holds and a bid that slips.
Garage Addition Contractors in Sun Village
Garage Addition Contractors in Sun Village deal with a specific problem that city contractors don’t always see coming: older single-story stock built on slabs and stem-walls that were never sized to carry a second floor. A garage addition here typically runs $70,000 to $140,000 when it’s a build-up above the existing footprint, and it often includes a foundation upgrade the homeowner didn’t budget for. We walk you through that before we ever write the contract, not after we open the walls.
Foundation Load Checks
Before we quote a build-up, we check what’s under the garage. The original slab, the stem-wall footing, the hold-down points. In Sun Village, a lot of garages from the 1970s and 1980s were poured with a one-story load in mind. That’s not a dealbreaker, but it is a real cost. We tell you what we find and we write the fix into the original price. No change order after demo.
County Plan-Check Reality
The Los Angeles County Department of Public Works administers Sun Village building permits, not a city hall. That means plan-check, inspection scheduling, and fire-clearance review all run on a county calendar. A bid that assumes a city turnaround will slip. We build the county’s actual schedule into your project timeline before we start, and we tell you which submittals the county will ask for so you’re never blindsided.
Bathroom Addition Contractor in Sun Village

A Bathroom Addition Contractor working in Sun Village has to answer one question first: can the existing plumbing carry the new wet wall, or are we running a new line from the street? On older Sun Village slabs, that answer changes the price by $8,000 to $15,000. A new bathroom addition here typically runs $45,000 to $90,000, depending on whether you’re tying into existing waste lines or cutting new ones.
Slab Work and Drainage
Most Sun Village homes sit on slab foundations, not raised floors. Adding a bathroom means cutting concrete, sloping new waste lines, and often re-working the existing cleanout. We price that work line-by-line before you sign. You’ll know exactly where the trench goes and what it costs to backfill and patch it.
County Inspection Notes
A new bathroom means a new fixture count, and L.A. County will want to see a plumbing isometric and a fixture unit calculation. We pull those drawings and stand with you through the inspection. When the county’s structural inspector signs off at rough framing, we take the photo and send it to you same day. That’s the Relay Visibility Guarantee in practice.
Trusted Brands We Service in Sun Village
We’re authorized to build with the industry’s leading prefab and materials brands, which means Sun Village homeowners get curated options instead of a single take-it-or-leave-it product. For a home addition, that matters most at the cladding and envelope stage. James Hardie siding holds up in Antelope Valley sun and wind. For an ADU or attached addition, Abodu and Cover deliver precision-built prefab panels that cut framing time on-site and keep your county inspection schedule predictable. Dvele gives us a high-performance shell option when you want wellness-grade indoor air and lower utility loads. We stock common parts and materials for Sun Village customers, so we’re not waiting on a truck from downtown L.A. when your project is mid-frame.
Common Home Addition Contractor Problems We See in Sun Village Homes
- Assuming the L.A. County plan-check counter works like a city building department. County response times and fire-clearance submittals change the schedule. A bid that assumes city turnaround will slip and inflate. We price for the county’s actual timeline from day one.
- Quoting a garage addition without confirming the slab or stem-wall footing will carry the new load. In Sun Village’s older single-story stock, a foundation upgrade is the most common mid-project change order. We check the foundation before we quote, not after we open the walls.
- Under-scoping grading and drainage on desert-adjacent Antelope Valley lots. A new addition’s roof runoff and footing excavation can trigger a drainage plan or a soils report the homeowner never expected. We factor that into your written price up front.
- Treating every bathroom addition as a tie-in job. Older Sun Village slab homes often have cast-iron waste lines that have shifted or cracked. Cutting concrete to find a failed line is a real discovery. We show you what a worst-case tie-in costs before you commit.

FAQs About Home Addition Contractor in Sun Village
The Los Angeles County Department of Public Works issues building permits for Sun Village. Sun Village is an unincorporated community, not a city with its own building department, so plan-check, inspection scheduling, and fire-clearance review all run through county offices on a county calendar. We prepare plans and submittals that meet county requirements and walk your project through the process. Call (903) 568-7222 for an exact quote on your addition, including county fees and timeline.
Many won’t, and that’s the single biggest pricing risk on a Sun Village garage build-up. Older slabs and stem-wall footings were sized for one-story loads, so a second story often requires new perimeter footings, hold-downs, and shear panels before framing starts. We inspect the foundation before we quote and write any needed upgrade into the original price. Call (903) 568-7222 and we’ll check your garage first, not after the walls come open.
Often yes. The county will require a soils report when a new addition changes roof runoff or when footing excavation hits expansive or poorly drained soil, which is common in the desert-adjacent Antelope Valley lots around Sun Village. We identify whether your project needs one before you commit, and we include the geotech cost in your written price. Call (903) 568-7222 and we’ll tell you what your specific lot will require.
Plan-check runs through the Los Angeles County Department of Public Works, and the county calendar is slower than a city hall counter in most cases. First submittal review can take several weeks, and fire-clearance submittals add another layer. We build that county timeline into your project schedule so you never sign a bid that assumes a faster city process. Call (903) 568-7222 for a realistic calendar based on what we’re seeing in Sun Village right now.
Sometimes, but it depends on the age and condition of your waste lines. Older Sun Village slab homes often have cast-iron or clay waste pipe that may have shifted or cracked. Sharing the existing line saves money when the line is sound; cutting a new line from the street adds $8,000 to $15,000. We camera the existing line before we quote so you know which path you’re on. Call (903) 568-7222 and we’ll scope it for free as part of your estimate.
