about the process
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.

California moved its ADU law into Government Code sections 66310 through 66342 in 2024, and it changed again on January 1, 2026: square footage is now measured as interior livable space, and an agency has 15 business days to determine whether an application is complete and 60 days to approve or deny it. Approval is ministerial — no hearing, no discretionary design review.
For a property in Jurupa Valley, that application goes to the City of Jurupa Valley Building and Safety Department. One local factor worth knowing: the city only incorporated on July 1 2011, so original plans and permit history for most existing houses were filed with Riverside County rather than with the city.
Riverside County’s own ADU ordinance is the oldest of the four counties we serve — Ordinance 348, adopted in 2023 — and in May 2025 the California Department of Housing and Community Development issued formal findings identifying eighteen provisions that do not comply with state law, including a height cap of one story or 16 feet, a junior ADU capped at 50 percent of the primary dwelling, and a parking requirement for interior ADUs. State law preempts all of them. A homeowner reading the county handout would conclude they can build less than the law actually allows.
Riverside also runs a strong pre-approved plan program. Its Permit Ready ADU set offers four free plans, from a 499 square foot studio to a 909 square foot two-bedroom, three of which fall under 750 square feet and therefore below the state impact fee threshold. The program excludes parcels in flood hazard or environmental constraint areas, so the first question on any site here is which map it sits on.
The lot decides most of the rest. Housing here was largely built before the city existed, as Rubidoux, Glen Avon, Pedley and Mira Loma suburbanized from quarry and dairy land through the mid and late twentieth century, with newer tracts added around the July 2011 incorporation, and the typical home is a single story ranch style house on a larger semi rural lot, typically with a modest original kitchen closed off from the living room, which shapes where a detached unit can sit and how far the utilities have to run.

Why Choose Horizon Remodeling As Your ADU Contractor In Jurupa Valley ?
Horizon Construction & Remodeling builds ADUs as a licensed Class B general building contractor, CSLB #938230, bonded and insured, with more than 15 years of design-build work behind us. One company draws the plan, runs it through the agency, and builds it.
Riverside County is the clearest example we work in of why it pays to have someone who reads the statute rather than the handout. We design to state law and cite it, and we plan around the constraints that are real here — summer heat, wind design in the desert communities, and whether the parcel falls in a flood hazard or environmental constraint area that removes the pre-approved plan option. The protections you keep either way: no owner-occupancy requirement for an ADU, no sprinkler retrofit triggered on the main house, and no impact fees on a unit of 750 square feet or less of interior livable space.
We work on ADU projects in La Quinta, Lake Elsinore and Menifee. Landmarks and neighborhoods we work around in Jurupa Valley include Rubidoux, Glen Avon, Mira Loma, Pedley.

ADU Contractor in Jurupa Valley FAQ
What is an ADU and why should I build one?
An ADU, or Accessory Dwelling Unit, is a secondary housing unit built on your property—like a backyard cottage, garage conversion, or in-law suite. Building an ADU with Horizon Remodeling allows you to expand your living space, create a rental income opportunity, or provide independent living space for family members.
How much does it cost to build an ADU in California?
The honest answer is that it depends on things we cannot know from a web page: the size and type of unit, whether it is a conversion or new detached construction, the site work and utility runs your lot needs, and the finish level you choose. What we can tell you is where the money goes and what the law protects you from. An ADU of 750 square feet or less of interior livable space is exempt from impact fees; school fees apply only above 500 square feet; and connection fees for a conversion or a junior ADU are limited, because the state does not treat those as a new residential use. Building an ADU also cannot trigger a fire sprinkler retrofit of your main house. Anyone quoting a firm price before seeing the parcel is guessing — we walk the property, confirm the utility and setback situation, and then give you a fixed scope and price you can hold us to.
One warning worth repeating: the CalHFA ADU grant program is closed, its funding fully allocated, and the agency itself warns that anyone offering to help you obtain an ADU grant is running a scam.
Do I need permits for an ADU in Jurupa Valley?
Yes — an ADU always requires a building permit, but approval is ministerial rather than discretionary, so there is no hearing and no design review. For a property in Jurupa Valley the application goes to the City of Jurupa Valley Building and Safety Department. State law gives the agency 15 business days to determine completeness and 60 days to approve or deny, and a pre-approved plan cuts that review to 30 days. Horizon prepares and submits the package and carries it through inspections rather than handing it back to 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.
