Kitchen Remodeling In Ontario

Older bungalows along Ontario’s north side grid often have small, closed-off kitchens that no longer fit how families cook and gather, while newer Ontario Ranch homes call for layouts that flow naturally into an open great room. Our kitchen remodeling services cover custom cabinets, countertops, tile work, and reconfigured layouts built for real daily use. Browse layout and finish ideas at HGTV Kitchen Ideas.

Bathroom Remodeling In Ontario

A dated bathroom in a postwar tract home or a builder-grade bath in an Ontario Ranch two-story can both be brought up to current standards with the right plan. Our bathroom remodeling solutions cover vanities, tilework, fixtures, and full layout changes from powder rooms to primary baths. For finish and fixture ideas, visit Houzz Bathroom Remodel Ideas.

Interior Remodeling In Ontario

Many north side bungalows were built with compartmentalized rooms that feel tight by modern standards, and opening those layouts takes careful structural planning. Our interior remodeling work covers open-concept conversions, custom staircases, and layout changes that hold up over time. See design approaches from Architectural Digest for broader planning context.

Exterior Remodeling In Ontario

Ontario is a Certified Local Government with its own historic preservation ordinance, so exterior work on designated landmarks or within historic neighborhoods may require a Certificate of Appropriateness before construction starts. We coordinate that process alongside siding, stucco, and trim work through our exterior remodeling expertise. Additional guidance on exterior upgrades is available at This Old House – Exterior Upgrades.

Room Additions & ADUs In Ontario

Ontario’s mix of older grid lots and larger Ontario Ranch parcels creates different opportunities for expanding living space, and both building types can support well-planned room additions and ADUs suited to multigenerational living, a home office, or rental income. Permits go through the City of Ontario Building Department. State-level rules are outlined in California’s HCD ADU Guide.

Garage Conversions In Ontario

Detached garages on older north side lots and attached two-car garages in Ontario Ranch neighborhoods can both be converted into livable space when the scope is planned correctly. Our garage conversion projects address insulation, framing, and City of Ontario Building Department permit requirements from the start. Browse finished examples at Houzz Garage Conversions.

Outdoor Living Spaces In Ontario

Southern California’s climate makes backyard living practical for most of the year, and Ontario homes from the Euclid Avenue corridor to Ontario Ranch benefit from purpose-built outdoor living features like patios, pergolas, and BBQ islands sized to the lot. Find layout and material ideas at Better Homes & Gardens – Outdoor Spaces.

Flooring & Painting In Ontario

Hardwood, luxury vinyl plank, and other finish materials are part of the broader scope we manage when updating Ontario homes, and our flooring services are coordinated alongside other trades rather than performed as a standalone job. Interior and exterior painting services follow the same approach, with finish work completed as part of a larger remodeling project.

Window & Door Installation In Ontario

Replacing windows and doors in older Ontario bungalows or postwar tracts typically improves energy performance and ties into Title 24 compliance requirements that apply to permitted remodeling work. Our window and door replacements are selected and installed to meet current efficiency standards. Performance criteria for qualifying products are listed at Energy Star – Windows.

Home Remodeling Construction and Design Services in Ontario

Home remodeling in Ontario means working across one of the more layered housing markets in the Inland Valley, and that layering shapes every project we take on. Since 2009, Horizon Construction and Remodeling Inc. has been handling additions and whole-home remodels as a licensed and bonded Class B general building contractor. Ontario’s residential stock stretches from the original Chaffey-era grid established after the city’s founding and 1891 incorporation, through mid-century postwar tracts, all the way to the two-story homes that have gone up in Ontario Ranch since the New Model Colony was annexed in 1999. Knowing which era a home belongs to tells us a great deal before we ever open a wall.

The differences between a north-side bungalow with a compartmentalized floor plan and a newer Ontario Ranch house built around an open great room are not cosmetic. They are structural and logistical. An older bungalow on the grid typically requires more planning to relocate load-bearing walls and update systems to current California Title 24 standards, while a newer tract home often offers cleaner paths for an addition at the rear or side yard. All permit applications for this work go through the City of Ontario Building Department, and we handle that coordination from the start so nothing stalls mid-project.

One factor that catches some homeowners off guard is Ontario’s status as a Certified Local Government. The city operates its own historic preservation ordinance and commission, which means exterior alterations on designated landmarks or properties within recognized historic neighborhoods may require a Certificate of Appropriateness before permits can move forward. We research that question during pre-design so your plans reflect what the city will actually approve. Reach out today to request a free estimate and find out what your home and lot will support.

Professional Design & Personal Attention from Start to Finish

Why Choose Horizon Remodeling For Home Remodeling in Ontario

We run a design-build process, which means the drawings, structural engineering, permitting, and construction all stay with one company from start to finish. For a project in Ontario, that matters because the City of Ontario Building Department handles permits directly, and keeping everything under one roof reduces the back-and-forth that slows projects down. Our office at 614 S Euclid St in Fullerton is open if you want to look at materials and displays before settling on a scope.

Ontario’s housing spans a wide range of eras, from the original Chaffey-era bungalows on the north side grid to the two-story tract homes in Ontario Ranch that have been going up since the New Model Colony was annexed in 1999. Older homes on that grid often have compartmentalized layouts with separate kitchens, while newer Ontario Ranch houses typically open the kitchen into a great room. The remodeling approach we take reflects which generation of construction your home belongs to.

One thing worth knowing on the financial side: school facility fees attach to a residential addition only when it adds more than 500 square feet of assessable space. Garages, patios, covered walkways, and detached accessory structures generally do not count as assessable space. There is also a disaster reconstruction exemption documented in county guidance, covering rebuilds up to the original footprint plus 500 square feet.

Horizon Construction & Remodeling Inc. holds a Class B General Building license and serves homeowners across a wide region of Southern California. Our home remodeling work in Ontario draws on years of experience coordinating multi-trade projects, and we pull all required permits through the City of Ontario Building Department.

Ontario’s housing stock spans a long range of eras and styles. Older bungalows on the north-side Chaffey grid often have separate, compartmentalized kitchens that many owners want opened up, while newer two-story tract homes in Ontario Ranch more commonly need updated finishes, additional square footage, or structural changes to aging systems. Each era presents its own set of conditions, and we plan accordingly.

Because Ontario is a Certified Local Government with its own historic preservation ordinance and commission, exterior work on designated landmarks or in historic neighborhoods can require a Certificate of Appropriateness before a building permit is issued. We coordinate that process alongside the standard permit application so nothing stalls the project.

We also serve homeowners throughout Orange County, San Bernardino County, Riverside County, and Los Angeles County, including communities such as Anaheim, Fullerton, Chino, Chino Hills, Montclair, Corona, Long Beach, Pasadena, Glendale, Burbank, and many others across the region.
