#1 ADU Contractor in Eastvale
Custom Builds by Horizon Remodeling
Horizon Construction & Remodeling Inc. builds accessory dwelling units and home additions throughout Eastvale, managing every step from initial design and budgeting through material selection, permits, and the final walkthrough. Because Eastvale’s housing stock dates almost entirely from the late 1990s through the 2010s, the framing and systems we work with are current-era construction, which keeps the structural side of an ADU project straightforward. We coordinate with the City of Eastvale Building and Safety Division to keep your project code-compliant from the first submittal forward.

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 the right adu contractor in Eastvale means working with a team that understands both the current state of California ADU law and the specific permit process the city uses. California consolidated its ADU statutes into Government Code sections 66310 through 66342 in 2024, and those rules were updated again on January 1, 2026. Under the current framework, square footage is calculated as interior livable space only, an agency has 15 business days to confirm an application is complete, and 60 days to approve or deny it. Approval is ministerial, meaning no public hearing and no discretionary design review.
For Eastvale homeowners, that application goes directly to the City of Eastvale Building and Safety Division within the Community Development Department. Knowing the right office matters because submitting to the wrong agency adds weeks to a project. We handle that coordination for you, preparing the package so it meets the city’s completeness checklist before it ever crosses the counter.
Riverside County runs a Permit Ready ADU program offering four pre-approved plan sets at no cost, ranging from a 499 square foot studio to a 909 square foot two-bedroom. Three of those plans fall under 750 square feet, which is significant because state law exempts ADUs below that threshold from most impact fees. The program does exclude parcels in flood hazard or environmental constraint areas, so confirming which maps apply to your specific lot is always the first step.
Eastvale’s housing stock shapes ADU planning in a practical way. Because the city was built almost entirely on converted dairy land between the late 1990s and the 2010s, the homes here feature recent engineered framing and current-era construction rather than outdated systems that require replacement before work can begin. That generally simplifies structural tie-ins and utility connections compared to older communities.
The typical Eastvale home is a large two-story tract house on a slab with an open floor plan, which directly affects where a detached ADU can be sited and how far electrical, water, and sewer lines need to run to reach it. We evaluate those conditions during our initial site review so there are no surprises once construction begins.

Why Choose Horizon Remodeling As Your ADU Contractor in Eastvale ?
Horizon Construction and Remodeling is a licensed Class B general building contractor, bonded, and in business since 2009. We handle the full scope of an ADU project under one roof: design, permit submission through the City of Eastvale Building and Safety Division, and construction. Keeping everything with one company removes the coordination gaps that slow projects down.
Eastvale’s housing stock is almost entirely from the late 1990s through the 2010s, built on slabs with engineered framing as dairy land gave way to master planned subdivisions. That means we are working with current-era construction rather than aging systems, which simplifies structural planning. State ADU law provides several protections worth knowing: no owner-occupancy requirement applies to an ADU, no sprinkler retrofit is triggered on the main house, and no impact fees are assessed on a unit with 750 square feet or less of interior livable space.
We are familiar with Eastvale communities including Eastvale Gateway, The Enclave, Cloverdale Farms, and Orchard Glen. Parcel conditions, setbacks, and any environmental or flood hazard constraints all factor into the plan we bring to the Building and Safety Division on your behalf.

ADU Contractor in Eastvale FAQ
What is an ADU and why should I build one?
An accessory dwelling unit, or ADU, is a self-contained secondary residence on your property, typically built as a backyard cottage, a converted garage, or an in-law suite. Working with Horizon Construction and Remodeling on an ADU in Eastvale gives you the option to generate rental income, house extended family, or simply gain usable living space on a lot that already sits within one of the city’s master-planned subdivisions.
How much does it cost to build an ADU in California?
ADU costs in Eastvale shift based on factors we can only assess in person: the size of the unit, whether you are converting an existing space or building a detached structure from the ground up, how far utility lines need to run across your lot, and the finish level you select. Because virtually every home here was built between the late 1990s and the 2010s on engineered slab foundations with current-era framing, the structural baseline tends to be predictable, which helps us scope work accurately once we walk the property. What we can tell you upfront is where the money goes. Units at or under 750 square feet of livable space are exempt from impact fees. School fees apply only above 500 square feet. Connection fees for a conversion or junior ADU are limited because state law does not classify those as a new residential use, and adding an ADU cannot trigger a fire sprinkler retrofit on your existing home.
Permits for ADU work in Eastvale run through the City of Eastvale Building and Safety Division within the Community Development Department, and we manage that process for you from application through final inspection. Any contractor quoting a firm number before visiting the parcel is estimating blindly. We walk the site, confirm setbacks and utility conditions, and then give you a fixed scope and price you can hold us to. One point worth stating plainly: the CalHFA ADU grant program is closed and its funding is fully allocated. The agency itself has warned that anyone offering to help you obtain an ADU grant is running a scam.
Do I need permits for an ADU in Eastvale?
An ADU always requires a building permit, but state law makes approval ministerial rather than discretionary, meaning there is no hearing and no design review board to satisfy. Applications for Eastvale properties go to the City of Eastvale Building and Safety Division within the Community Development Department, which has 15 business days to confirm completeness and 60 days to approve or deny. A pre-approved plan shortens that review window to 30 days. Because most homes here were built from the late 1990s onward on engineered slab foundations, the permit package tends to be straightforward rather than complicated by aging infrastructure. Horizon prepares and submits everything, then carries the project through every required inspection so the process never falls back on the homeowner.
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.
