Cover ADU in Bloomington, CA | Sunstone ADU Builders
We provide independent ADU Builders – Bloomington Cover service across Bloomington, CA, from initial site assessment to final county sign-off. What makes our Cover work different here is simple: Bloomington is unincorporated San Bernardino County territory, so every Cover plan has to clear San Bernardino County Land Use Services, not a city building department. That changes the entitlement path, the fees, and the timeline. Sunstone ADU Builders is not Cover-authorized or manufacturer-affiliated. We build to Cover’s published design standards while flagging where a plan needs field modification before the county sees it. Call (855) 949-1913 for a free estimate.
Why Bloomington Residents Choose Us for Cover Service
We know Cover packages inside out, from the studio to the two-bedroom, and we also handle Cover service in Rialto. Nate Holloway, our owner, spent two decades working residential construction across Orange County before focusing exclusively on ADUs, and he has shepherded Cover projects through San Bernardino County Land Use Services on Bloomington’s flat, alley-access lots. That combination matters. A builder who knows Cover but not the county will burn your timeline. A builder who knows the county but not Cover will burn your budget. We know both.
We install Cover’s specified panels and connectors where they’re correct. Where the stock package won’t handle Bloomington’s reality, we substitute equal-or-better rated equipment: ENERGY STAR cooling, Title 24-compliant insulation assemblies, upgraded service panels. You get the Cover design you researched, adjusted for the lot you actually own, whether here or with our Cover repair in Glen Avon. And because we also do kitchen and bathroom finishing in-house, the unit is move-in ready without a second contractor.
Common Cover ADU Problems We Solve in Bloomington
- Stock insulation that bakes by mid-afternoon. Cover’s standard insulation and ventilation assumptions are tuned for coastal loads. On a 100°F Bloomington summer day, the standalone unit needs an upgraded attic and roof assembly or it turns into an oven by 2 p.m. We rework the assembly before the panels land.
- Panels that assume a level, compacted pad. Bloomington’s older county tracts often have gravel rear access and unpaved side yards. Cover’s prefab panel sets assume a flat, compacted foundation. The grading and foundation rework has to happen first, or the panels won’t seat correctly.
- Garage conversion kits that don’t fit the garage you have. Cover’s garage-conversion package assumes a standard two-car attached garage. Bloomington’s post-war housing stock includes plenty of detached and shallow garages. The partition layout, bathroom stub, and panel upgrade all have to be re-sequenced for the actual structure.
- Electrical packages undersized for a real ADU. Cover’s default electrical package frequently under-sizes the service drop for a full ADU with its own HVAC and range. In Bloomington, that panel upgrade needs to be folded into the county submittal early, not discovered mid-project.
- Cooling load planning that never got done. The Inland Empire heat is not a footnote. A Cover ADU in Bloomington needs real cooling load planning, shaded or west-facing-glare mitigation, and Title 24 compliance for a standalone structure without the main house’s thermal mass. We handle all of it before the county reviews the plans.
Cover Service in Bloomington: What Local Conditions Mean for Your Equipment
Because Bloomington is unincorporated county territory, a Cover ADU here is entitled through San Bernardino County Land Use Services rather than any city building department. That is not a technicality. On the alley-access lots off Valley Blvd, the county’s rear-setback and utility-trench review, not a city planner, is what actually decides whether your detached unit gets its own rear driveway. We have sat in those reviews. On a half-acre parcel off Valley Blvd with gravel rear-alley access, our crew took a Cover garage conversion package into the existing detached garage and hit the county’s utility-trench review first. We re-graded and compacted a level pad, swapped in a higher-SEER cooling unit and Title 24 attic assembly for the 100°F summers, and upgraded the service panel before the county signed off on the rear driveway approach. The county’s process has a personality all its own. You want a builder who has already met it on Bloomington lots.
Cover Models & Products We Service in Bloomington
We work on the full Cover lineup: the detached studio ADU with its flat or low-slope roof, the one-bedroom detached, the two-bedroom detached, and the garage conversion package for attached or detached garages. Our parts approach is straightforward. Where Cover’s specified panels and connectors are correct for the site, we install them. Where they are not, we substitute equal-or-better rated components and tell you exactly why. Stocked locally for fast Bloomington turnaround: Title 24 insulation assemblies, higher-SEER cooling units, and service panel components sized for a full ADU electrical load. You are never waiting on a coastal distributor to ship something inland.
Cover Service Pricing in Bloomington
Cover service in Pedley follows similar county rules, but here in Bloomington, Cover ADU service pricing depends on what the county review demands and what the lot gives you. Foundation and grading rework on gravel or unpaved rear access adds cost. Panel upgrades add cost. Title 24 compliance on a 100°F-plus summer climate adds cost. A free estimate from Sunstone tells you the real number before you commit. We provide written line-item quotes, and our fixed pricing means no change orders mid-project. Call (855) 949-1913 and we will walk your Bloomington lot with you.

FAQs – Cover ADU in Bloomington
County. Bloomington has no municipal building department, so your Cover ADU entitlement, permits, and inspections all run through San Bernardino County Land Use Services. That is the entire path. Call (855) 949-1913 if you want us to walk you through what the county will ask for on your specific parcel.
Yes, on many of the larger lots off Valley Blvd and the older county tracts, the rear lot line has gravel or dirt alley-style access. The county’s rear-setback and utility-trench review decides whether the driveway approach is approved, not a city planner. We have gotten these approved. Call (855) 949-1913 for a site-specific read on your rear access.
No. Cover’s stock insulation and ventilation assumptions are tuned for coastal loads, and Bloomington regularly hits 100°F-plus in summer. The standalone unit needs an upgraded attic and roof assembly or it bakes by mid-afternoon. We spec Title 24-compliant insulation assemblies before the county reviews the plans. Call (855) 949-1913 for an exact quote on the upgrade.
It depends on your garage and your rear access. Many Bloomington post-war homes have detached or shallow garages that force re-sequencing of the Cover conversion package. On a half-acre lot with rear alley access, a ground-up detached unit with its own driveway often pencils out better. We will tell you honestly which is the better spend. Call (855) 949-1913 and we will walk the lot with you.
Usually yes. Cover’s default electrical package frequently under-sizes the service drop for a full ADU with its own HVAC and range. The panel upgrade has to be folded into the county submittal early. Call (855) 949-1913 for a free estimate on the full electrical scope.

Written by Nate Holloway, Owner at Sunstone ADU Builders, serving Bloomington and the Inland Empire. Nate grew up in North Tustin, not far from Peters Canyon Regional Park, and spent enough weekends exploring those trails to know he never wanted to leave. He learned the fundamentals of residential construction through the building trades program at Santiago Canyon College in Orange, then spent two decades working on everything from custom home additions to garage conversions before focusing exclusively on ADUs. An ADU should feel like a natural part of your property, not an afterthought bolted onto the back of it.
