#1 ADU Contractor in Banning
Custom Builds by Horizon Remodeling
Horizon Construction & Remodeling Inc. builds accessory dwelling units in Banning, managing design, permitting through the City of Banning Building and Safety, and construction under one general contract. Many properties here sit in the San Gorgonio Pass wind corridor, so structural work is engineered to meet the higher wind-load criteria that apply in this area. We coordinate every trade involved, from foundation work to finished interiors, whether the project adds a detached backyard unit or converts existing square footage. Specialty work is handled by appropriately licensed subcontractors we bring in and oversee.

How Our ADU Process Works
When it comes to enhancing your living space, room additions combined with Accessory Dwelling Unit (ADU) construction offer unparalleled versatility and value. These projects not only increase square footage but also provide additional living accommodations, whether for extended family, rental income, or work-from-home setups, making them a popular choice for homeowners seeking to maximize their property’s potential. According to California’s Department of Housing and Community Development, ADUs are a key solution to expanding housing options in urban and suburban neighborhoods.

Finding a qualified adu contractor in Banning means working with someone who understands both California state law and the specific local conditions that shape what you can actually build on your property. California consolidated its ADU statutes into Government Code sections 66310 through 66342 in 2024, and the rules shifted again on January 1, 2026. Square footage is now calculated as interior livable space rather than overall building area, and a local agency has 15 business days to determine whether a submitted application is complete, then 60 days to approve or deny it.
Approval is ministerial under state law, meaning no public hearing and no discretionary design review. In Banning, that application goes directly to the City of Banning Building and Safety division, which sits within the Community Development Department. Knowing which office handles your permit and what the current review timeline looks like helps you plan your project schedule realistically from the start.
One structural reality specific to Banning is that the city falls inside a mapped special wind region in the San Gorgonio Pass. Riverside County design criteria impose higher wind loads here than the standard countywide baseline, and every structural component of a new unit has to be engineered to meet them. That requirement applies whether the unit is detached or attached, small or large.
Riverside County maintains a Permit Ready ADU program offering four pre-approved plans ranging from a 499 square foot studio to a 909 square foot two-bedroom. Three of the four plans fall under the 750 square foot state threshold below which impact fees generally do not apply. The program excludes parcels in flood hazard or environmental constraint areas, so the first question on any Banning site is which mapped zone the lot sits in.
Banning’s housing stock adds another layer to that question. The city grew in two distinct waves, an older core dating to the decades after incorporation in 1913 and a much larger suburban build-out from the 1980s forward, when the population rose from roughly 14,000 to nearly 30,000 by 2010. Many properties in areas like Sun Lakes Country Club feature single-story ranch plans with compact, walled-off kitchens rather than open layouts, which directly affects where a detached unit can be sited and how far water, sewer, and electrical connections need to run.

Why Choose Horizon Remodeling As Your ADU Contractor in Banning ?
Horizon Construction and Remodeling is a licensed Class B general building contractor, bonded, and in business since 2009. We handle ADU projects in Banning from initial drawings through permit submittal to the City of Banning Building and Safety and on through finished construction, all under one contract.
Banning sits inside a mapped special wind region in the San Gorgonio Pass, which means structural design here must meet higher wind load criteria than the countywide baseline. We account for that from the start, along with summer heat exposure and any flood hazard or environmental constraint that might affect your parcel and limit which approval path is available to you.
A few state ADU protections apply regardless of those local conditions. No owner-occupancy requirement applies to an ADU. Adding an ADU does not trigger a sprinkler retrofit on your existing home. And impact fees are waived on any unit with 750 square feet or less of interior livable space. We work throughout Banning, including Sun Lakes Country Club, Atwell, downtown along Ramsey Street, and the Banning Bench.

ADU Contractor in Banning FAQ
What is an ADU and why should I build one?
An accessory dwelling unit is a secondary home on your existing property, taking the form of a backyard cottage, a garage conversion, or an in-law suite. Building one with Horizon Construction and Remodeling can generate rental income, house extended family, or simply add usable living space. Because Banning sits in the San Gorgonio Pass wind region, structural design here must meet elevated wind load requirements.
How much does it cost to build an ADU in California?
Pricing an ADU in Banning depends on details no contractor can settle from a distance: the unit size, whether the work involves a conversion of existing space or new detached construction, what utility runs your lot requires, and the finish level you select. What the law does pin down are certain fee limits that protect you regardless of scope. A unit at or under 750 square feet of livable interior space is exempt from impact fees. School fees apply only when the unit exceeds 500 square feet. Connection fees for a junior ADU or a garage conversion are capped, because state law does not classify those as a new residential use. Adding an ADU also cannot force a fire sprinkler retrofit on your existing home.
Before we give you a fixed scope and price you can actually hold us to, we walk the property, confirm setbacks, and review what the City of Banning Building and Safety will require through its Community Development Department permitting process. Because Banning sits inside the San Gorgonio Pass wind region, structural design here must meet higher wind load criteria than the Riverside County baseline, and that reality factors into how we scope the work. One point worth repeating clearly: the CalHFA ADU grant program is closed, its funds fully allocated, and the agency itself states that anyone offering to help you obtain an ADU grant today is running a scam.
Do I need permits for an ADU in Banning?
Yes, an ADU always requires a building permit, but the approval process is ministerial rather than discretionary, meaning there is no hearing and no design review board to satisfy. Applications for properties in Banning go to the City of Banning Building and Safety, which operates within the Community Development Department. State law gives the agency 15 business days to confirm completeness and 60 days to issue a decision, though a pre-approved plan shortens that review to 30 days. Horizon prepares and submits the full permit package and follows it through every inspection, so the process does not fall back on you.
How long does ADU construction take with Horizon Remodeling?
Most ADU construction projects take between 4 to 8 months from design to completion, depending on scope and permit approvals. Horizon Remodeling prioritizes efficient timelines while maintaining quality workmanship.
What types of ADUs can Horizon Remodeling build?
We specialize in building detached ADUs, attached ADUs, garage conversions, backyard cottages, and junior ADUs (JADUs). Our team can help you choose the right ADU style for your property and goals.
Can I build a detached ADU on my property in Banning?
Yes, if your property meets California zoning and space requirements. Horizon Remodeling will assess your site, secure the necessary permits, and build a fully detached ADU tailored to your preferences.
Is Horizon Remodeling licensed to build ADUs in my area?
Yes, Horizon Remodeling is fully licensed, bonded, and insured to build ADUs throughout Orange County and surrounding areas. We have over 18 years of experience delivering high-quality ADU projects.
