Benson ADU Santa Clarita is an independent Cover service provider that plans, permits, and builds home additions for homeowners who already own or want to pair a Cover prefab unit with additional square footage.

We give every homeowner a written price before any work starts, so you know the number before you commit.

How Cover Products Fail – and How We Fix Them
Cover units are well-engineered prefab structures, but when we’re called in to add square footage or tie a new addition into one, we see the same issues repeat. Homeowners in Santa Clarita deal with heat, Santa Ana winds, and occasional heavy rain, and that weather exposes weak points fast. Here’s what we encounter most:
- Foundation settling at the transition line. Cover builds on its own engineered foundation system, and when you add a room addition, the new foundation butts up against the existing one. We see differential settling in Santa Clarita areas like Canyon Country and Saugus where soil expands and contracts through dry summers and wet winters. The fix is a properly engineered tie-in with a flexible transition joint, not just bolting the two slabs together and hoping for the best.
- Weather barrier gaps at roof intersections. When a bump-out or second-story addition meets the Cover roofline, the flashing has to be perfect. In Valencia and Newhall, wind-driven rain finds any gap. We’ve repaired leaked intersections where the original flashing was installed by a contractor unfamiliar with Cover’s roofline pitch. We strip back, re-flash with proper step flashing, and test with water before sealing.
- Drywall stress cracks along the original joint. Thermal movement between a Cover unit and a stick-built addition is real. Santa Clarita’s 90-plus degree summer days and near-freezing winter nights cause expansion and contraction. We see hairline cracks at the exact point where the original Cover wall meets the new addition. Our fix includes installing a movement joint and using flexible drywall compound at transitions, then repainting to match.
- Electrical panel capacity limits. Cover’s prefab electrical setup is designed to code at time of manufacture, but adding a sunroom, bathroom, or second story often pushes the existing panel past capacity. We regularly upgrade panels or add subpanels in Santa Clarita additions. Before framing starts, we run a load calculation so the addition doesn’t trip breakers on day one.
- Stucco or siding mismatch at the addition wall. Cover units have a specific exterior finish. Matching it with site-built framing and materials takes skill. We’ve seen additions where the texture difference is visible from the street. We match the original finish as closely as the material allows and, where an exact match isn’t possible, we design a clean architectural break so the transition looks intentional, not like a patch job.
We also service Abodu and Dvele units, so if you have multiple prefab structures on the property or are comparing brands for a future build, we can talk through the differences honestly.
Our Cover Home Addition Contractor Process
Every project runs the same way, whether it’s a 200-square-foot bump-out or a full second story. Here’s the process from first call to final walkthrough:
- 1
Call and conversation. A live person answers at (661) 219-7906. We ask about your Cover unit, the addition you’re planning, and whether you have any existing drawings or permits.
- 2
Site visit and measurements. Troy Eastman or a senior crew lead comes out, measures everything, checks the existing Cover foundation and roofline, and takes photos. We’re looking for tie-in points, grading, and any existing issues that will affect the addition.
- 3
Written price and scope. You get a line-item cost breakdown on paper before you decide anything. No verbal ballparks. Price it in writing, build it right, no surprises – that’s the whole job.
- 4
Permits and engineering. We pull plans, get engineering stamps where required, and submit to the City of Santa Clarita. You don’t chase paperwork. We do.
- 5
Build and document. Our background-checked, uniformed crew does the work. You get photo updates, a live arrival time, and a digital invoice you can pay by link. No wondering who’s showing up or when.
- 6
Final inspection and the 365-Day Done Right Promise. We walk the job with you, fix anything that isn’t right, and put the guarantee in writing. If something fails within a year of completion, we come back and make it right.

Why Santa Clarita Homeowners Call Benson ADU Santa Clarita for Cover Work
Most contractors see a prefab structure and either overcharge because they don’t understand it or underbid because they’ve never touched one. We’ve worked on Cover units across Santa Clarita, and we treat the intersection between prefab and site-built as a skill, not an afterthought. Troy Eastman grew up in the San Fernando Valley watching his older relatives gut and rebuild everything from garages to guest rooms, and he studied construction technology at Los Angeles Trade-Technical College where load-path rules got drilled into his head. Over a decade of ADU work later, he’s the builder who sits at your kitchen table with a printed cost breakdown instead of a vague ballpark.
Every project carries a written guarantee. If it’s not done right within 365 days, we make it right. Our technicians are background-checked and arrive in uniform, so you always know who’s on your property. A live person answers the phone around the clock, every day. And because we also build with Abodu, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie materials, we can give you independent, honest comparisons if you’re weighing whether to add to your Cover or start fresh with something else.
FAQs
Yes. We plan and build home additions that tie into existing Cover structures, including room additions, bump-outs, sunrooms, garage conversions, and second-story work. We handle the engineering, permits, and construction as an independent contractor. Call (661) 219-7906 for a free site consultation.
It depends on what the addition touches and how it’s tied in. We take a warranty-conscious approach: we document the existing condition before we start, use compatible tie-in methods that don’t compromise the Cover structure, and keep the original envelope intact wherever we can. If you have your Cover warranty documents, we’ll review them with you before any work begins.
Most projects run 3 to 6 months from first call to final inspection. Permits with the City of Santa Clarita typically account for 4 to 8 weeks of that, depending on scope and current review queues. We give you a written timeline with the written price, and we track progress with photo updates so you know exactly where things stand.
For additions, we source building materials locally and through our supplier network. Where the addition meets the Cover unit, we use compatible products that match or exceed the original spec. For any existing Cover component that needs repair during the addition (roofing, flashing, stucco), we match materials as closely as possible and tell you upfront if an exact OEM match is required. Call (661) 219-7906 to discuss your specific project.
A bump-out is typically cheaper because it extends an existing space without adding a new foundation footprint in the same way a full room addition does. Bump-outs run $30,000 to $75,000 in Santa Clarita, while full room additions start around $80,000. The honest answer depends on your lot, your Cover unit’s placement, and what you want the space to do. We’ll show you both options with written pricing.
