#1 ADU Contractor in Moreno Valley
Custom Builds by Horizon Remodeling
Horizon Construction & Remodeling Inc. builds ADUs and home additions for homeowners across Moreno Valley, handling design, budgeting, permit coordination with the City of Moreno Valley Building and Safety Division, and material selection from start to final walkthrough. Most homes here are single-story or two-story stucco tract houses built in the 1980s and 1990s, and we account for site-specific constraints like the Primary Animal Keeping Overlay, which can affect where an accessory structure may be placed on qualifying lots.

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 Moreno Valley means working with someone who understands both California state law and the specific rules that apply to properties here. 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, 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, meaning no public hearing and no discretionary design review.
In Moreno Valley, applications go through the City of Moreno Valley Building and Safety Division. That is the body responsible for reviewing plans, issuing permits, and scheduling inspections for any ADU project within city limits. Knowing which office handles your application and what that office requires is a practical starting point before any design work begins.
One local factor that affects site planning is the Primary Animal Keeping Overlay in the city zoning code. On qualifying rural residential and residential agricultural lots, the overlay requires designated animal keeping areas, and that requirement directly limits where an accessory structure can be placed on the parcel. We check zoning constraints like this before finalizing any site plan.
The housing stock here also shapes the conversation. Most homes in Moreno Valley were built during the 1980s and 1990s, a period of rapid growth that took the city from roughly 50,000 residents at its 1984 incorporation to nearly 120,000 by 1990. The typical result is a single story or two story stucco tract house on a slab, which determines how far utilities need to run to reach a detached unit.
Riverside County operates 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 those plans fall under 750 square feet, placing them below the state impact fee threshold. The program excludes parcels in flood hazard or environmental constraint areas, so the first question on any site is which maps apply to that specific lot.

Why Choose Horizon Remodeling As Your ADU Contractor in Moreno Valley ?
Horizon Construction and Remodeling is a licensed Class B general building contractor, bonded, and has been doing design-build work since 2009. For an ADU project in Moreno Valley, that means one company draws the plans, submits them to the City of Moreno Valley Building and Safety Division, and builds the finished unit. Keeping everything under one roof cuts down on the back-and-forth that slows projects down.
Moreno Valley grew fast in the 1980s and 1990s, and most of the housing stock reflects that era. If your property falls under the city’s Primary Animal Keeping Overlay, that zoning designation can limit where an accessory structure may legally sit on the lot, and we plan around that from the start rather than discovering it mid-permit. Summer heat loads and any flood hazard or environmental constraint areas on the parcel also factor into how we design and document the project.
A few protections California state law provides are worth knowing. There is no owner-occupancy requirement for an ADU, no sprinkler retrofit triggered on the main house, and no impact fees on a unit with 750 square feet or less of interior livable space. We work throughout Moreno Valley, including areas like Sunnymead, Edgemont, Moreno, and Rancho Belago.

ADU Contractor in Moreno Valley FAQ
What is an ADU and why should I build one?
An accessory dwelling unit is a secondary home built on your existing property, taking the form of a converted garage, a backyard cottage, or an in-law suite. Adding one in Moreno Valley lets you bring in rental income, house extended family, or simply gain usable square footage on lots where many of the original tract homes still have room to grow.
How much does it cost to build an ADU in California?
ADU costs in Moreno Valley depend on details that vary from lot to lot: the size and type of unit you want, whether you are converting an existing structure or building a new detached unit from the ground up, how far utility lines need to run across your property, and the finish level you choose. What we can tell you upfront is where the money goes and what state law protects you from. Units at or under 750 square feet of interior livable space are exempt from impact fees, school fees apply only above 500 square feet, and connection fees for a conversion or junior ADU are limited because the state does not classify those as a new residential use. A sprinkler retrofit of your main house cannot be required as a condition of building the ADU.
Moreno Valley’s zoning also includes a Primary Animal Keeping Overlay that applies to qualifying rural residential and residential agricultural lots, and that designation can affect where an accessory structure is permitted to sit on the parcel. The City of Moreno Valley Building and Safety Division reviews and issues permits, so we confirm setbacks, utility conditions, and any overlay restrictions before quoting anything. Anyone offering a firm price without walking the property is guessing. One point worth stating plainly: the CalHFA ADU grant program is closed, its funding fully allocated, and the agency itself warns that anyone claiming they can help you obtain an ADU grant is running a scam.
Do I need permits for an ADU in Moreno Valley?
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 Moreno Valley go through the City of Moreno Valley Building and Safety Division, which has 15 business days to determine completeness and 60 days to approve or deny a standard submittal, though a pre-approved plan shortens that review to 30 days. We prepare and submit the full package and carry the project through every inspection, so the process does not fall 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.
