Cover ADU in San Bernardino, CA | Fullerton ADU Builders
We install, retrofit, and service Cover ADU systems across San Bernardino, and the biggest surprise for most homeowners is that the Cover unit itself is rarely the hard part. The real work usually happens before the panelized walls ever arrive: legalizing an unpermitted rear garage, upgrading a 100-amp panel on a mid-century home, or clearing Title 24 for inland heat that coastal units were never spec’d for. We’re an independent Cover service provider, not manufacturer-affiliated or authorized, so our recommendations are driven by what your San Bernardino lot actually allows. Call (877) 801-4497 to schedule a free estimate.
Why San Bernardino Residents Choose Us for Cover Service
Glen Pacheco, our owner, grew up framing additions on his family’s street in Fullerton and has spent years working through residential projects across Southern California before narrowing his focus to ADUs. That background matters on San Bernardino’s 1940s-1970s stucco tract homes, where the wiring, plumbing, and slab under your existing garage don’t always match what the Cover factory drawings assume. We’ve worked with Cover’s panelized systems in enough 92404 and 92405 backyards to know exactly where the standard package needs adjusting before the city will sign off. Our Cover sales & service work covers everything from single-room studio units to two-bedroom builds and garage-conversion packages, and we always use Cover’s OEM panels and connectors where they matter structurally while upgrading electrical, HVAC, and plumbing components sized for San Bernardino’s summer heat. One contractor, one crew, and a straight answer about what your property needs.
Common Cover ADU Problems We Solve in San Bernardino
These are the issues we see repeatedly on Cover in Highland and across San Bernardino, and most of them are tied directly to the city’s older housing stock and inland valley climate:
- Factory cooling spec runs short in July and August. Cover’s standard energy package is designed for milder coastal conditions. On a 100-plus-degree San Bernardino afternoon, a west-facing unit with the factory insulation and glazing will run hot and expensive. We upsize the cooling and shade the west glazing before the unit ever gets a final inspection.
- No default fire-rated detailing near the foothills. The standard Cover panel assembly doesn’t include ignition-resistant vents or non-combustible skirting. For units sited toward the San Bernardino foothills, where Santa Ana winds push fire risk, those additions have to be made at install, not after.
- Unpermitted garage slabs as a foundation problem. Cover ships plans for a clean, flat pad. In 92404 and 92405, the rear pad often sits over an old garage slab or a converted structure with unknown footings. The factory plan assumes a site condition that frequently doesn’t exist, so we document what’s actually there before anything gets ordered.
- Undersized sewer laterals on mid-century lots. Cover’s catalog footprint and wet-wall location assume a compliant sewer lateral. On homes built in the 1940s through 1960s in 92404 and 92405, the existing lateral is often undersized or shallow, which forces utility rework the standard package simply doesn’t account for.
- 100-amp panels can’t carry the added load. A Cover unit with a mini-split, water heater, and kitchen appliances pulls real amperage. Most San Bernardino mid-century homes still run on 100-amp service. We’ve upgraded enough panels across 92408, 92410, 92411, and 92412 to know the city’s plan check will flag this every time.
Cover Service in San Bernardino: What Local Conditions Mean for Your Equipment
San Bernardino’s deep, flat mid-century lots in 92404 and 92405 are the best ADU candidates in Southern California, and that’s not marketing. The lots are wide and rectangular, the land values are comparatively low, and a detached unit at the back of the property genuinely pencils out here in a way it doesn’t in Los Angeles or Orange County. But there’s a catch that’s more common in San Bernardino than almost anywhere else we work: many of those rear garages were built without permits, or converted into living space years ago with no city approval and no as-built drawings. That means the first job on a lot where you want a new Cover unit is often legalizing or documenting the existing structure before the city will even look at the new permit. A well-planned ADU doesn’t start with a floor plan, it starts with knowing what your property will actually allow. We handle the as-built documentation, the panel upgrade, and the existing-structure legalization as part of the same project, so the Cover install doesn’t stall at plan check. On a corner lot off Del Rosa Avenue in 92404, a homeowner wanted a Cover one-bedroom unit set on the pad behind an old detached garage. The garage had been converted years ago with no permit and an aging 100-amp panel feeding it. We pulled the as-built documentation, upgraded the service panel, cleared Title 24 for the hotter inland climate with upsized cooling and shaded west glazing, and got the existing garage legalized alongside the new Cover install so the city would sign off on both at once.
Cover Models & Products We Service in San Bernardino
We service the full Cover lineup that shows up in San Bernardino backyards: the Cover studio ADU, the one-bedroom unit, the two-bedroom model, and the garage-conversion package. Our parts approach is simple. We use Cover’s OEM panels and connectors where structural integrity matters, and we switch to quality aftermarket electrical, HVAC, and plumbing components when the factory spec is undersized for inland valley conditions. We keep common replacement parts and panel touch-up materials on hand for faster turnaround on San Bernardino service calls, and we’ll tell you straight when legalizing an existing conversion is the smarter financial move versus ordering a new Cover unit.
Cover Service Pricing in San Bernardino
Every Cover project in San Bernardino carries different costs depending on what the lot gives us to work with. Legalizing an unpermitted garage, upgrading a 100-amp panel, reworking a shallow sewer lateral, and upsizing cooling all land on the final number, and they’re not always obvious from the start. That’s why we do a free, no-obligation site walk where we document what’s actually on your property before we quote anything. You’ll get a written line-item estimate that covers the Cover unit, the site work, the permits, and the utilities, all from one contractor. Call (877) 801-4497 for an exact quote on your San Bernardino property.

FAQs – Cover ADU in San Bernardino
Yes, but the existing structure nearly always has to be documented or legalized through the City of San Bernardino before a new Cover unit can be permitted on that same pad. We pull the as-built drawings, file the paperwork, and handle the legalization alongside the new install so both are signed off together. Call (877) 801-4497 and we’ll walk your lot first.
Not without adjustment. Cover’s factory energy package is built for milder coastal climates, and San Bernardino’s inland valley summers will push a standard-spec unit hot. We upsize the cooling, add shaded west-facing glazing, and clear Title 24 for the hotter climate as part of the install. Estimates are free, so call (877) 801-4497 to talk about your specific lot.
Probably not. Most homes in 92405 still run on 100-amp service, and a Cover unit with cooling, a water heater, and kitchen appliances will overload it. We upgrade the panel as part of the project, which is also what gets you through plan check without a correction. Call (877) 801-4497 for a free site assessment.
Yes. Cover’s standard panel assembly doesn’t carry ignition-resistant detailing by default, so units sited toward the foothills need fire-rated vents and non-combustible skirting added at install. We build that into the scope for foothill adjacent lots, not as a change order later. Call (877) 801-4497 and we’ll check your fire zone during the free walkthrough.
It depends on what’s already back there. On a deep San Bernardino lot, a garage conversion often pencils out cheaper than a new Cover unit, but only if the existing structure can be legalized without extensive structural rework. We’ll give you an honest cost comparison between the two paths after one site visit. Call (877) 801-4497 to see both numbers side by side.
