Cover ADU in Davis, CA | Benson ADU Sacramento
We provide independent Cover ADU service across Davis as our ADU Builders in Davis, and we know exactly how Cover’s panelized systems behave under this city’s zero-net-energy ordinance and its older slab conditions. That’s the thing most contractors miss here. Davis is not Woodland, and it’s not Dixon. If your Cover unit needs repair, retrofit, or a full build, call (279) 254-1808 and we’ll put the price in writing before anything gets touched.
Our crews have retrofitted and built Cover ADUs across Davis’s older tract neighborhoods and newer subdivisions, so we know how Cover’s panels interface with post-tensioned slabs, 100-amp legacy panels, and Title 24 all-electric requirements. We’re an independent service provider, not a Cover factory affiliate. That means we recommend what fixes your problem, not what protects a corporate relationship.
Why Davis Residents Choose Us for Cover Service

Cover builds a genuinely smart panelized ADU. The S Series, M Series, and L Series all ship as precision-cut panels that lock together faster than site-built framing. But precision factory tolerances meet messy real-world slabs here, and that’s where experience matters. Troy Eastman, who leads our build team, has been working ADU projects across the Sacramento region for years. He grew up in the San Fernando Valley and picked up his first framing hammer before he could legally drive, then got serious about the trade at Los Angeles Trade-Technical College. That background means he can read a 1968 garage slab the way a mechanic reads an engine. We are the independent Cover service provider Davis homeowners call when they want someone who has actually seated Cover panels on the specific slabs and electrical services this city throws at you.
We stock Cover-specified OEM fasteners and panel components locally, and we carry aftermarket weather-resistive barriers and flashing from regional suppliers so a lead-time delay doesn’t stall your project. Background-checked, uniformed technicians show up when we say they will. A live person answers the phone around the clock. And every promise goes in writing before a single shovel turns.
Common Cover ADU Problems We Solve in Davis
- Misaligned panel joints at roof-to-wall intersections. Older Davis garages routinely have slab leveling variances from the 1960s. When a Cover panel system seats on a crowned or sloped slab, the roof-to-wall joints open up slightly, and winter tule fog finds its way in as air and moisture infiltration. We shim, grind, or add perimeter blocking as needed, then re-flash those joints so they stay tight.
- Breaker trips on 100-amp main panels. A Cover unit’s heat pump and induction cooktop running together can overload a legacy panel on older Davis homes. We size the load properly, upgrade panels when needed, and make sure the all-electric system actually works without flickering every time you make dinner.
- Condensation inside wall cavities. Davis’s cool Delta breeze nights meeting warm interior air is a recipe for condensation, especially because Cover’s tight panel seams leave little room for airflow. If vapor barriers aren’t lapped correctly, moisture gets trapped. We inspect seam laps and correct them before damage spreads.
- Improper flashing where prefab walls meet stucco. Attached garage conversions in Central Davis often have this failure. Where Cover’s prefab wall meets an existing stucco surface, bad flashing leads to dry rot, and post-tensioned slab homes hide that rot longer than you’d like. We replace and re-flash properly.
- Panel delamination from heat exposure. A panel with water staining or delamination loses insulation value quickly in Davis’s hot, dry summers. We replace rather than patch any compromised panel, because patching a damaged Cover panel in this climate just buys you another failure next summer.
Cover Service in Davis: What Local Conditions Mean for Your Equipment
Davis’s zero-net-energy ordinance requires every new ADU to be all-electric with no natural gas. That sounds simple, but it changes how a Cover unit gets serviced here. You won’t run a gas line extension, which saves money. What you will do is upgrade the electrical panel and size a heat pump properly for a unit that heats, cools, cooks, and heats water all on electricity, which is why working with a Home Addition Contractor in Davis who knows these requirements matters. Neighbors in Woodland or Dixon rarely face that. On a detached garage conversion off E Street in Central Davis, our tech found the post-tensioned slab had a 2-inch crown under the original 1968 garage, so a stock Cover S panel kit wouldn’t seat without shimming. We ground the crown flat, added perimeter blocking, and flashed the panel base with a reinforced sill gasket before installing the Cover roof system. It passed the Title 24 blower door test on the first try. That’s the difference between knowing Cover panels and knowing Davis slabs.
Cover Models & Products We Service in Davis
We service the full Cover lineup: the S Series studio and one-bedroom backyard units, the M Series two-bedroom models, and the L Series larger custom-layout units. We also work on Cover’s Accessory Dwelling Unit panel system in conversion scenarios. For structural continuity, we use Cover-specified OEM panels and fasteners. When OEM lead times drag, we substitute quality aftermarket weather-resistive barriers and flashing from local suppliers so a Davis project doesn’t stall. We stock common Cover-compatible fasteners and sealants in our Sacramento shop for fast turnaround, which matters when a panel seam opens up in November and the fog starts rolling in.

Cover Service Pricing in Davis
Here’s what you should know before you call. A site assessment for a Cover repair or retrofit in Davis typically runs $150 to $300, and that fee is credited toward the work if we do the repair. Panel replacement runs $800 to $2,800 per panel depending on the model and access. Electrical panel upgrades for all-electric Cover units on older Davis homes generally land between $2,500 and $6,500 depending on service size and trenching. Foundation retrofit work on post-tensioned slabs without perimeter footings starts around $4,000 and goes up based on what the slab actually looks like.

FAQs – Cover ADU in Davis
Correct. Davis requires new ADUs to be all-electric with no natural gas connection. You’ll need an induction cooktop and an electric heat pump for water and space heating. On older homes, that usually means a panel upgrade. We’ll size the electrical load properly during the site assessment so your Cover unit runs without tripping breakers. Call (279) 254-1808 and we’ll walk through what your specific house needs.
Yes, but it’s not a drop-and-go situation. Many Central Davis garages sit on post-tensioned slabs without perimeter footings, and a Cover panel system needs a stable, level base. We assess the slab, grind crowns if needed, add perimeter blocking, and install a reinforced sill gasket before seating the panels. The foundation work sometimes costs more than the panel kit itself, and we’ll tell you that before you spend anything. Call (279) 254-1808 for a written assessment.
Probably not, especially with the all-electric requirement. A heat pump, induction cooktop, and electric water heater running together can pull more load than a 100-amp panel safely serves. We’ll evaluate your service size and either add a subpanel or upgrade the main panel. The exact cost depends on your panel, your meter location, and the distance to the ADU. Call (279) 254-1808 and we’ll put real numbers on it.
Cover’s panel seams are tight, which is good for air sealing but means moisture has nowhere to go if vapor barriers aren’t lapped correctly. Davis’s tule fog combined with Delta breeze nights can push condensation into wall cavities. We check seam laps, verify flashing details, and correct any gaps during our service visits. A correctly detailed Cover unit handles Davis winters fine. A poorly lapped one doesn’t. Call (279) 254-1808 to schedule an inspection.
Yes. The Cover M Series is a two-bedroom unit designed to fit within standard residential setbacks on Davis’s deeper lots. We’ll verify your specific lot dimensions, setback requirements, and Title 24 solar and all-electric mandates during the site assessment. Call (279) 254-1808 and we’ll confirm what fits before you commit to a floor plan.
