#1 ADU Contractor in Victorville
Custom Builds by Horizon Remodeling
Horizon Construction & Remodeling Inc. builds accessory dwelling units and home additions across Victorville, managing design, permitting through the City of Victorville Building Division, material selection, and budgeting under one roof. The city’s housing stock runs heavily toward single-story stucco tract homes built during the 1980s through the 2000s, and the age and condition of that construction is what typically shapes the scope of an ADU project. We coordinate every trade involved so the finished unit meets current building code and works with your existing home.

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.

If you are looking for an adu contractor in Victorville, understanding how state law and local permit requirements work together is the first step toward a project that actually gets built. California moved its ADU law into Government Code sections 66310 through 66342 in 2024, and updates effective January 1, 2026 changed how square footage is counted, measuring interior livable space only. Those same updates set a 15-business-day window for an agency to determine whether an application is complete and a 60-day deadline to approve or deny it. Approval is ministerial, meaning no public hearing and no discretionary design review stands between a compliant application and a permit.
For a Victorville property, that application goes to the City of Victorville Building Division. No unusual local overlay applies here, so what governs your project is the state building code and the age of your specific house. That is actually straightforward compared to some jurisdictions, and it means the plan we draw has to answer to the code, not to a separate set of local design rules layered on top of it.
San Bernardino County adopted a new ADU chapter, Development Code Chapter 84.36, at the Board of Supervisors on January 13, 2026. Under those published standards, an ADU can range from 200 to 1,200 square feet, a junior ADU reaches up to 500 square feet, and height limits are 25 feet attached and 18 feet detached, with two additional feet allowed to match an existing roof pitch. Side and rear setbacks are four feet, with five feet of separation required between detached structures. Two provisions stand out compared to coastal counties: two ADUs per lot are permitted, and properties of five acres or more can have three units.
Sewer access shapes feasibility on a significant number of parcels in this area. A connection is required when a sewer line runs within 200 feet of the property line, and that distance grows by 100 feet for each additional dwelling unit. When a connection is not required, the project goes to septic or an advanced treatment system. We bring Environmental Health into the conversation before a single plan is drawn, not after, because discovering a septic requirement late in the process costs time and money.
The physical character of Victorville housing adds another layer of planning. Most of the housing stock went up during the 1990s and 2000s growth surge that pushed the population from roughly 40,000 to over 115,000, and the typical home is a single-story stucco tract house on a flat lot with an open floor plan oriented toward a family room. That layout, combined with flat lot geometry, shapes where a detached unit can realistically sit and how far utility runs will need to extend. We factor that in from the first site visit so the design we develop reflects what your specific lot can actually support.

Why Choose Horizon Remodeling As Your ADU Contractor in Victorville ?
Horizon Construction and Remodeling is a licensed Class B general building contractor, bonded, and in business since 2009. We handle ADU projects in Victorville from initial planning through final inspection, with one team managing the drawings, the permit submission to the City of Victorville Building Division, and the construction itself.
Most Victorville homes are single-story stucco tract houses built during the 1980s through the 2000s, and the building code along with the age of that structure is what governs what an ADU requires here. No unusual local overlay complicates the process, so feasibility comes down to the existing home, the lot, and what the city reviews. We work through those questions before design begins. State law protections apply regardless of where your parcel sits: no owner-occupancy requirement is attached to an ADU, adding one does not trigger a sprinkler retrofit of the main house, and units with 750 square feet or less of interior livable space are not subject to impact fees.
We build ADUs across Victorville, including areas like Old Town Victorville, Mesa Linda, Sunset Ridge, and along the Bear Valley Road corridor. Specialty trade portions are performed by appropriately licensed subcontractors coordinated by our team.

ADU Contractor in Victorville FAQ
What is an ADU and why should I build one?
An accessory dwelling unit is a self-contained secondary home on your property, built as a backyard cottage, a garage conversion, or an in-law suite. In Victorville, where most homes are single-story stucco tract houses on flat lots, that existing footprint often makes an ADU practical to add, giving you rental income or independent space for family.
How much does it cost to build an ADU in California?
ADU costs in Victorville depend on details no contractor can assess from a distance: the size and type of unit you want, whether you are converting an existing space or building a detached structure on your lot, how much site work and utility running your specific parcel requires, and the finish level you choose. Because most Victorville homes are single-story stucco tract houses built during the 1980s and 2000s boom, a garage conversion often involves less structural work than new detached construction, but the City of Victorville Building Division still reviews every project, and the age of the house along with standard building code requirements are what govern the scope of work.
State law does protect you on several cost items. An ADU under 750 square feet of livable interior space is exempt from impact fees. School fees only apply above 500 square feet. Connection fees for a conversion or junior ADU are capped because the state does not classify those as a new residential use. Building an ADU also cannot force a fire sprinkler retrofit on your main house. Any contractor quoting a firm number before walking your property is guessing. We confirm setbacks, utility conditions, and site realities first, then give you a fixed scope and price. One warning: the CalHFA ADU grant program is closed and fully allocated, and the agency itself states that anyone offering to help you obtain that grant is running a scam.
Do I need permits for an ADU in Victorville?
Yes, every ADU requires a building permit. In Victorville, that application goes directly to the City of Victorville Building Division, and state law sets the review clock at 15 business days for a completeness determination and 60 days for an approval or denial. Because much of the city’s housing stock went up during the 1990s and 2000s growth surge on flat tract lots, most properties connect to city sewer, but the sewer proximity rule still gets checked, and connection is required when a line runs within 200 feet of the property line. Where a septic system or well is involved, Environmental Health becomes part of the review. We handle the submittal, respond to any correction notices, and coordinate every inspection.
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.
