ADU Company in Bloomington, CA

Kitchen remodeling in Bloomington often means opening up a 1950s-1980s ranch home that was built for a different era of living. These older stucco houses have closed-off galley kitchens, worn cabinets, and layouts that trap summer heat. Cottage ADU Builders handles kitchen renovations alongside ADU work for Bloomington homeowners who want one contractor relationship from permit to punch-list.

Why Bloomington Homes Are Different

Bloomington sits unincorporated in San Bernardino County, which changes how permits, setbacks, and utility approvals get handled. Where Rialto and Fontana run their own municipal ADU desks, Bloomington projects route through County planning and building. That means our team works with County reviewers on setbacks, and with the local environmental health office when a property is on septic and a private well. A large share of Bloomington lots are half-acre or more, and many run on septic systems rather than city sewer. Before a kitchen addition or an ADU gets drawn, the percolation test and water-supply assessment often decide what is feasible. The housing stock is mostly single-story ranch and stucco homes from the 1950s through the 1980s, with detached garages and wide unpaved side yards. Summer heat here is serious: temperatures push past 100°F, and Santa Ana winds raise dust and ember exposure at lot edges. Kitchens and ADUs need real cooling loads, reflective roofing, and shade planning. The dry climate keeps moisture issues lower than coastal builds, but it also means we plan for expansion, dust intrusion, and fire-wise exterior materials. James Hardie fiber-cement siding is a good fit for this climate: it holds paint longer, resists ember exposure, and does not warp in dry heat the way vinyl can. Bloomington’s large lots and older interiors make it a prime market for adding square footage and reworking the original home at the same time.

Our Main Bloomington Services

Two jobs dominate the calls we get from Bloomington homeowners: building new ADUs and refreshing outdated bathrooms. Both are covered in detail on their own pages.

ADU Builders in Bloomington

Most Bloomington ADU projects begin with a question about the lot. Half-acre parcels on septic and well systems need a capacity check before any design gets locked. We walk homeowners through County setbacks, utility sequencing, and the choice between a garage conversion, a detached unit, or a prefab delivery from brands like Mighty Buildings or Boxabl. The full breakdown is on our ADU Builders in Bloomington page.

Bathroom Remodeling in Bloomington

Older Bloomington ranches tend to have compact bathrooms with original cast-iron tubs, dated tile, and single-sink vanities. We rework these spaces for better ventilation, storage, and water efficiency, often while an ADU is under construction on the same property. Details on timelines, layouts, and costs are on our Bathroom Remodeling in Bloomington page.

Kitchen Remodeling in Bloomington

Kitchen remodeling in Bloomington usually starts with a tired galley or closed-off cook space in a 1950s-1980s ranch home. The heat here is dry and intense, so we plan for ventilation, cooling, and materials that hold up when doors and windows stay shut through summer. Some homeowners pair a kitchen refresh with an ADU build so one crew handles both. For the full scope of what we do, see our Kitchen Remodeling hub. A kitchen remodel in Bloomington typically runs $28,000 to $65,000 depending on cabinet grade, layout changes, and finish level.

Cabinet Replacement

Signs you need it

Cabinet boxes are swollen, doors no longer close square, or the layout forces you to work in a cramped triangle with no landing space.

What it costs in Bloomington

Cabinet replacement in Bloomington typically runs $12,000 to $28,000 for a standard 10×12 kitchen with mid-grade full-overlay doors.

How we do it

We measure and template the existing space, remove old boxes without disturbing adjacent walls, then install new cabinets with level tops, soft-close hardware, and scribe trim fitted to Bloomington’s older, often out-of-square ranch walls.

Countertop and Backsplash Upgrade

Signs you need it

Laminate counters are delaminating, tile grout is cracked and stained, or you want a surface that handles heat and daily use without constant sealing.

What it costs in Bloomington

Countertop and backsplash replacement in Bloomington typically lands between $4,000 and $12,000 depending on slab material and linear footage.

How we do it

We template after cabinets are set, fabricate quartz or granite to fit the exact run, install a full-height backsplash, and re-set sinks and fixtures with new plumbing connections.

Full Kitchen Renovation

Signs you need it

The layout fights how you actually cook, storage is not meeting daily needs, and the space needs new plumbing, electrical, lighting, and ventilation work together.

What it costs in Bloomington

A full kitchen renovation in Bloomington typically costs $35,000 to $65,000 when walls, plumbing, electrical, and finishes are all in scope.

How we do it

We coordinate the demo, rough plumbing and electrical, drywall, flooring, cabinet and countertop install, and finishing trades as one sequence, pulling County permits and scheduling inspections so the homeowner has one point of contact.

What Kitchen Remodeling Costs in Bloomington

Item Typical range in Bloomington
Cabinet replacement $12,000 – $28,000
Countertop and backsplash $4,000 – $12,000
Full kitchen renovation $35,000 – $65,000

Why do Bloomington kitchen remodels need extra cooling design?

Bloomington summers push past 100°F, so older ranches without central air or with undersized returns make kitchens uncomfortable. We plan for ventilation, appliance heat output, and window placement rather than dropping in cabinets with no airflow plan.

Do I need County permits for a kitchen remodel in Bloomington?

If you are moving plumbing, electrical, or walls, yes. Bloomington is unincorporated, so permits come through San Bernardino County. We pull them as part of the job and schedule inspections. Call (866) 808-7312 to talk through scope.

Brands We Service in Bloomington

We work with the brands you have likely been researching already. For Bloomington ADUs, that often means Mighty Buildings, Boxabl, and Plant Prefab for the structure, with Tuff Shed for garage and accessory solutions. We also install James Hardie fiber-cement siding on applicable projects. See our brands for the full list.

Prices in Bloomington climb when a home is on septic, because kitchen work that adds a sink or moves plumbing can trigger a septic system review through County environmental health. We give a written line-item quote before work starts, and the price does not change mid-project.

What Bloomington Customers Say

★★★★★ 4.8 from 4+ reviews

"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."

— Ernesto Hernandez

"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."

— Shane Miller

"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."

— Amanda Walsh
