#1 ADU Contractor in Blythe
Custom Builds by Horizon Remodeling
Horizon Construction & Remodeling Inc. builds accessory dwelling units and home additions in Blythe, handling design, budgeting, City of Blythe permitting, and material selection under one contract. The generous flat lots common across West Blythe and the older neighborhoods along Hobsonway often leave room for a detached backyard unit or a connected addition without major site work. Because summer temperatures regularly push past 110 degrees, we coordinate insulation levels, HVAC sizing, and heat-tolerant finishes from the planning stage so the finished space stays livable year-round.

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 Blythe starts with understanding how state law and local permitting actually work together on your specific lot. California consolidated its ADU rules 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 rather than overall footprint, and any agency reviewing your application has 15 business days to determine whether it is complete and 60 days to approve or deny it. Approval is ministerial, meaning no hearing and no discretionary design review stands between a compliant application and a permit.
In Blythe, that application goes directly to the City of Blythe, which issues building permits for work inside city limits. That is a straightforward process compared to unincorporated areas, but it still requires a complete, code-compliant submittal from the start. We handle the drawings, the documentation, and the back-and-forth with the building department so nothing stalls your project at the counter.
Riverside County runs a Permit Ready ADU program offering four pre-approved plans at no cost, ranging from a 499 square foot studio to a 909 square foot two-bedroom. Three of those plans fall below 750 square feet, which matters because state law exempts units under 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 lot is the first practical question on any Blythe project.
Riverside County also adopted its own ADU ordinance, Ordinance 348, in 2023. In May 2025, the California Department of Housing and Community Development issued formal findings identifying eighteen provisions that conflict with state law, including a one-story or 16-foot height cap, a junior ADU size limit set at 50 percent of the primary dwelling, and a parking requirement for interior ADUs. State law preempts all of them. A homeowner relying on the county handout alone would likely conclude they can build far less than the law actually permits.
Blythe’s housing stock reflects decades of gradual growth since the city’s incorporation in 1916, and most properties here are single-story stucco or wood frame homes on generous flat lots with enclosed kitchens rather than open-plan layouts. That lot depth typically gives a detached ADU room to breathe, but it also means utility runs can be longer than on a compact suburban parcel. The desert climate adds another layer of planning: with summer temperatures averaging 85 to 110 degrees and a record high of 124, insulation values, HVAC sizing, and heat-tolerant finishes are not optional upgrades. We factor all of that into the design before a single permit application is submitted. Contact us today to request a free estimate and find out what your lot can support.

Why Choose Horizon Remodeling As Your ADU Contractor in Blythe ?
Horizon Construction and Remodeling builds ADUs in Blythe as a licensed Class B general building contractor, bonded, and with more than fifteen years of design-build work behind us. We handle the plan, the permit application to the City of Blythe, and the construction itself, so you are not coordinating between separate firms at each stage.
Blythe’s housing stock grew gradually across many decades on generous flat lots, and that history works in your favor. A single-story stucco or wood frame house on a larger parcel usually has room for a detached ADU without the setback struggles common on tighter urban lots. We plan around the real constraints here: Blythe’s hot desert climate, where summer temperatures regularly reach well above 100 degrees, means insulation values, HVAC sizing, and heat-tolerant finishes shape every ADU design from the start rather than being addressed at the end.
California state law provides protections worth knowing before you budget. No owner-occupancy requirement applies to an ADU, no sprinkler retrofit is triggered on the main house, and ADUs at or under 750 square feet of interior livable space are not subject to impact fees. We work throughout Blythe, including downtown along Hobsonway, West Blythe, and Hidden Beaches.

ADU Contractor in Blythe FAQ
What is an ADU and why should I build one?
An accessory dwelling unit is a self-contained secondary home built on your existing property, taking the form of a backyard cottage, a converted garage, or an in-law suite. Building one with Horizon Construction and Remodeling can open a rental income stream, give a family member independent living space, or simply put Blythe’s characteristically generous flat lots to better use.
How much does it cost to build an ADU in California?
What an ADU Actually Costs in Blythe and What the Law Protects You From
No contractor can give you a reliable number before walking your specific lot, and that is true whether you are adding a detached unit on one of Blythe’s characteristically generous flat parcels or converting existing square footage in an older single-story stucco home. The final cost shifts based on the size and type of unit you choose, the site work your property requires, how far utility runs need to travel, and the finish level you select. What we can tell you is how state law limits certain costs. An ADU of 750 square feet or less of livable interior space is exempt from impact fees. School fees apply only to units above 500 square feet. Connection fees are capped for conversions and junior ADUs because the state does not classify those as a new residential use. A new ADU also cannot force a fire sprinkler retrofit on your existing home.
Permits in Blythe run through the City of Blythe building department, so getting the scope right before you submit matters. We walk the property, 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 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 Blythe?
Yes, a building permit is required for every ADU, but the approval process is ministerial rather than discretionary, meaning there is no public hearing or design review board to clear. In Blythe, applications go through the City of Blythe, which handles all permits for work inside city limits. Under state law the city has 15 business days to confirm the application is complete and 60 days to approve or deny it, and a pre-approved plan can shorten that review window to 30 days. Horizon puts the permit package together, submits it, and sees it 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.
Can I build a detached ADU on my property in Blythe?
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.
