Cover ADU in Pomona, CA | Holloway ADU Builders
We provide independent Cover in La Verne and across Pomona, and one thing separates our work here from any other city we cover: the alley-garage electrical situation. Most Pomona Cover projects start with separating a shared 100-amp service before a single panel goes up. If you’re exploring a Cover unit for a lot in 91766, 91767, 91768, or 91769, call us at (855) 617-6356 and we’ll tell you straight what your service panel needs before we talk floor plans.
Why Pomona Residents Choose Us for Cover Service
We’ve worked alongside Cover’s prefab and modular systems since they entered the Southern California market, and our crew understands the panelized wall and roof assemblies, the factory electrical rough-in conventions, and the waterproofing details that make or break a Cover ADU on an older Pomona lot. Neil Trescott, our owner, learned the trade through Riverside City College’s building technology program and has spent years focused almost entirely on ADU work. He’s walked enough Pomona back alleys to know which garages are conversion-ready and which ones need a full service overhaul first.
We’re an independent builder, not a Cover dealer or manufacturer affiliate. That matters because our recommendation isn’t tied to moving inventory. If a Cover unit fits your lot, we’ll tell you. If a different approach makes more sense after we see your slab and service setup, we’ll tell you that too.
Common Cover ADU Problems We Solve in Pomona
- Roof ventilation failures in Pomona’s inland heat. Cover’s low-slope panelized roof assemblies work, but without added ridge and soffit venting, attic heat builds up through July and August. We see premature shingle and membrane failure on units that skipped this step because the standard spec wasn’t written for Pomona’s hot, dry summers.
- Shared electrical service on alley-garage lots. The 1950s-era 100-amp services across Pomona were rarely designed to feed a second dwelling. When a Cover ADU goes on a rear alley garage, the factory electrical interface assumes a dedicated service. We separate the meter and upgrade the panel as step one on nearly every project in 91766 and 91767.
- Drainage problems at the panel-to-foundation transition. Flat and low-slope garage roofs are common on Pomona’s east side. Winter rain backs up under the panel edge and wicks into the slab-on-grade if the flashing wasn’t detailed for that condition. We re-flash and correct drainage before water damage spreads.
- Solar heat gain in standard-glazed Cover units. Santa Ana wind events and summer sun expose weak window specs quickly. Standard glazing underperforms on west-facing Pomona lots without aftermarket shading or upgraded low-E panels. We address this during the site assessment, not after the first utility bill.
- Unpermitted garage conversions that need legalizing. Many Pomona garages were converted decades ago without permits. Before a Cover ADU can go in, the structure has to be brought to code. We repair and upgrade the existing shell rather than tear it down, which saves both cost and time.
Cover Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s what most Cover or Pomona ADU pages won’t tell you: on the east side of Pomona, the back-alley garages off streets like those in 91767 share a single electrical service with the main house. That’s a product of the 1940s-to-1960s tract housing pattern where one meter fed everything on the lot. Cover’s factory electrical interface assumes a dedicated service, and Pomona properties rarely have one. So every Cover project in these neighborhoods starts with panel separation and a new meter, a step neighboring cities with wider lots and newer service rarely require. If you skip this and try to feed a Cover ADU from the existing panel, you’re looking at overloaded breakers, flickering circuits, and a failed inspection. We handle this first so you don’t have to rip out drywall later. Let’s figure out what actually makes sense for your lot before we talk about anything else.
Cover Models & Products We Service in Pomona
We work with the full Cover line: the Cover ADU panelized unit, the Cover Garage Conversion ADU, the Cover Studio ADU, and the Cover One-Bedroom ADU. For structural and waterproofing integrity, we specify Cover’s factory replacement panels, connectors, and electrical interface components. For ventilation, flashing, and shading hardware, we often source aftermarket options because Cover’s stock details are undersized for Pomona’s climate. Keeping factory parts for the critical interfaces and upgrading the rest is how we get units to pass inspection and hold up long term.
Cover Service Pricing in Pomona
Service pricing depends on what your specific project needs. A panel separation and meter upgrade on a 1950s Pomona garage typically runs $4,000 to $6,000 depending on trenching distance and city requirements. Ventilation retrofits, drainage corrections, and Title 24 upgrades each land in their own range, and we’ll give you a written line-item quote before any work starts. Your free estimate includes a site walk and a straight answer on which approach fits your budget. Call (855) 617-6356 and we’ll schedule it.

FAQs – Cover ADU in Pomona
Yes, in most cases. The unpermitted conversion has to be brought up to current code first, and that usually means structural reinforcement, electrical separation, and drainage corrections. We’ve done this on several Pomona east-side garages. The existing shell stays; the building envelope and systems get repaired and upgraded to pass inspection. Call (855) 617-6356 and we’ll assess what your garage needs.
Because most 1940s-to-1960s homes in Pomona have a single 100-amp service feeding the whole lot, and a Cover ADU needs its own meter and dedicated circuit capacity. We separate the service, pull the new meter, and upgrade to a 200-amp panel before setting Cover panels. Skipping this step means failed inspections and overloaded circuits.
We re-flash the panel-to-foundation transition and add the ridge and soffit venting Cover’s stock assembly doesn’t include by default. Pomona’s winter rain will find any gap at the panel edge and wick into the slab. We detail drainage so water sheds away from the structure instead of pooling under it.
Yes, every new ADU in Pomona has to meet California’s Title 24 energy standards. For Cover units, that usually means upgraded glazing, proper roof venting, and sometimes added exterior shading to handle solar heat gain. We handle the compliance package as part of the project so you’re not chasing paperwork later.
Yes, and Pomona’s alley lots are actually some of the best candidates for detached Cover ADUs because the alley gives access without disturbing the main house. We also serve the Los Serranos Cover service area with similar lot configurations. The catch is the shared service we mentioned earlier. We handle the meter separation and then the Cover unit goes in cleanly. Call (855) 617-6356 for a free estimate on your specific lot.
