Cover ADU in Bloomington, CA | Cottage ADU Builders
We provide independent Cover ADU service throughout Bloomington, CA 92316 – from site assessment and County permit package through panel assembly and final inspection. What separates our Cover work here is the order of operations: in unincorporated Bloomington, your septic and well capacity gets reviewed by County of San Bernardino before the structure does, so we front-load that feasibility work rather than letting it ambush the project mid-build. If you own a half-acre-plus Bloomington parcel and you’re weighing a Cover Backyard ADU, garage conversion, or JADU, call us at (866) 808-7312 for a free site assessment. We’ll tell you straight whether the lot supports the kit before you spend a dollar on panels.
Why Bloomington Residents Choose Us for Cover Service
Cottage ADU Builders works with eight recognized ADU and building-materials systems – including Cover – and we install Cover’s factory-cut panel sets the way they were engineered to go together. Neil Stratton, our owner, spent years on residential builds across the Temecula Valley before focusing exclusively on ADUs, and he’s carried that framing and finish discipline into every Cover project we touch. Bloomington homeowners get a builder who knows the Cover tolerance stack: how the panels seat on the foundation, which connectors cannot be substituted, and where aftermarket HVAC and plumbing makes better sense than OEM extras.
We’re not a Cover dealer and we don’t pretend to be one. That independence matters in Bloomington because some lots here need a different system entirely – and we’ll say so. When a Cover kit does fit, we execute it end to end: site prep, foundation, panel assembly, utility hookup, Title 24 compliance, and interior finishing. Your lot, your budget, the right system. Call (866) 808-7312 to schedule a site assessment.
Common Cover ADU Problems We Solve in Bloomington
- Panel delivery arriving before County plan check clears. Cover’s factory-cut panels are manufactured to your drawings, but Bloomington permits route through County of San Bernardino, not a city counter like Rialto or Fontana. Reviews move slower than most owners expect. We sequence the order so panels don’t sit in your unpaved yard through a Santa Ana event while paper waits on a desk.
- Foundation anchors that don’t match Bloomington’s ground. Cover’s kit assumes a certain soil condition. Many Bloomington lots we walk have caliche-hardened ground, decades of compaction, and grading that’s never seen a structural spec. We re-engineer the slab or stem-wall before the first panel lands; otherwise the anchors are working against soil they weren’t designed for.
- Undersized cooling loads in inland summer heat. Bloomington sits east of the Cajon Pass, where July means consecutive triple-digit afternoons. A standard Title 24 package often underestimates the cooling demand. We re-run the load calc and spec the HVAC and shading accordingly – because a beautiful Cover shell that bakes by August isn’t livable square footage.
- Garage conversions colliding with decades of informal work. Bloomington’s older stock includes plenty of detached garages that have been casually wired, plumbed, and lived in for years. Cover’s conversion scope assumes a clean slate. We bring the existing slab and wiring to code first, then apply the Cover conversion panels – otherwise you’re bolting a legal system onto an illegal foundation.
- Well and septic capacity killing the project before design starts. On a half-acre Bloomington parcel with a private well and septic, the percolation rate and water-supply demand decide whether a two-bedroom Cover Backyard ADU is even feasible. We test early, before you commit to a model line. That’s not a Cover limitation – it’s a Bloomington reality few builders flag honestly.
Cover Service in Bloomington: What Local Conditions Mean for Your Equipment
Because Bloomington is unincorporated, a Cover ADU here goes through County of San Bernardino planning and building rather than a city counter – and on the area’s half-acre-plus parcels, septic and well capacity often get reviewed before the structure does. That’s the single biggest difference between a Cover build in Bloomington versus the same kit in Rialto or Fontana, and it shapes how we run every project. Take the lots off Cedar Avenue: many sit on private wells with septics sized for a single 1950s ranch house, not a second dwelling. Add a two-bedroom Cover Backyard ADU and the County wants percolation test data, tank capacity verification, and water-supply demand calculations before the first panel is even ordered. We handle that sequencing up front. On a recent half-acre parcel off Cedar with an old detached garage and a private well, our crew assessed a Cover garage-conversion configuration and found the existing slab and wiring set up for decades of informal use. We pulled the County permit package, answered the percolation and water-supply questions, then brought the garage and foundation to code before the Cover conversion panels went in – the owner ended up with a legal one-bedroom instead of a tear-out. Let’s figure out what your lot can actually do – then build it right the first time.
Cover Models & Products We Service in Bloomington
We install and service the full Cover product range: Cover Connect panelized custom ADUs, Cover Backyard ADUs in studio, one-, and two-bedroom configurations, and the Cover Garage Conversion program. We also handle Cover Junior ADU configurations for attached-garage and interior conversions. Our parts approach is straightforward: Cover’s factory-specified panels, structural connectors, and anchors go in exactly as the engineering drawings dictate. We don’t substitute those, ever. For the surrounding systems – HVAC, electrical panels, plumbing fixtures – we spec quality aftermarket components matched to Bloomington’s heat loads and the County’s inspection requirements. That keeps your structure true to Cover’s engineering while your mechanicals match the actual climate you live in.
If you’ve been researching Cover sales & service options and want a builder who knows the kit without being a sales rep for it, start with a conversation about your lot. We service the entire Bloomington service area including 92316.

|---|---|
| Site assessment & feasibility review | $250 – $500 |

Bloomington pricing swings on two things: what’s underground and what’s already standing. A lot with confirmed well and septic capacity and a clean build site runs lean. A lot with an old unpermitted garage conversion that needs electrical, slab, and plumbing brought to code before Cover panels can go up runs heavier. Your free estimate includes a walk of the parcel, a review of County permit history, and a written line-item scope. Call (866) 808-7312 to book one – the estimate costs nothing and it’ll tell you exactly what you’re working with.

FAQs – Cover ADU in Bloomington
Bloomington has no city building department – it’s unincorporated, so your Cover ADU permit comes from County of San Bernardino planning and building. We prepare and submit the full County package, including septic and well documentation where applicable. Call (866) 808-7312 and we’ll walk you through the exact submittal list for your parcel.
Often yes, but only after the County confirms your well yield and septic capacity support the additional dwelling. Many Bloomington parcels have septics sized for the original 1950s-1980s house only. We test early, before you commit to a Cover model. If capacity falls short, we’ll tell you what it costs to upgrade – and whether the lot math still works. Call (866) 808-7312 for a feasibility review.
Cover’s garage conversion program can replace an informal conversion with a habitable, permitted ADU – but the existing slab, wiring, and plumbing have to come up to code first. Bloomington has plenty of these legacy conversions. We assess what’s salvageable, then build the Cover conversion onto a foundation that actually passes inspection. Call (866) 808-7312 to have our crew look at what you’ve got.
The Cover shell is well-insulated, but the HVAC and shading have to be engineered for Bloomington’s actual heat loads – inland Inland Empire summers east of the Cajon Pass regularly push triple digits, with Santa Ana events layered on top. We re-run the cooling calc and spec the mechanicals and reflective roofing accordingly. A standard Title 24 package often undershoots here.
No. We’re an independent builder with deep Cover experience, not a manufacturer-authorized dealer or installer. That independence is the point: we can recommend Cover when it genuinely fits your Bloomington lot and tell you when a different system makes more sense. Call (866) 808-7312 to talk through your options without a sales pitch attached.
