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 ADU law lives in Government Code sections 66310 through 66342, 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 Stanton, that application goes to the City of Stanton Building Division within the Community and Economic Development Department. One local factor worth knowing: nine mobile home parks holding about 1,300 spaces sit inside the city, and alterations to an installed manufactured home are permitted by the state Department of Housing and Community Development rather than by the city.
The lot decides most of the rest. Stanton was built out after the city reincorporated in 1956, through the postwar boom of the late 1950s and 1960s, and the typical home is a compact postwar single-family house or a small multifamily unit on a tight lot, in one of Orange County’s densest cities at roughly 12,000 residents per square mile, which shapes where a detached unit can sit, how far the utilities have to run, and whether a garage conversion or a new detached build is the better answer. We walk the parcel and check setbacks, grade, equipment access and utility routes before drawing anything.
What state law protects wherever the parcel sits: a local agency cannot cap an ADU below 850 square feet of interior livable space, or 1,000 with more than one bedroom; side and rear setbacks cannot exceed four feet; owner-occupancy cannot be required for an ADU; building one cannot trigger a fire sprinkler retrofit of the main house; and there are no impact fees on a unit of 750 square feet or less.

Why Choose Horizon Remodeling As Your ADU Contractor in Stanton ?
Horizon Construction & Remodeling builds ADUs as a licensed Class B general building contractor, bonded and insured, with more than 18 years of design-build work behind us. Our office and showroom are at 614 S Euclid St in Fullerton, so Stanton is a short drive rather than a long-distance job.
A detached ADU is a small house — foundation, framing, roof, envelope, electrical service, plumbing, a kitchen and a bathroom — placed on a lot where a house already stands. Design-build matters more here than on a remodel, because the design decisions and the construction constraints are the same decisions. One company draws it, permits it and builds it, and where an association is involved we prepare that submittal alongside the building permit rather than after it.
Our ADU crews also work in Cypress, Westminster and Garden Grove. Landmarks and neighborhoods we work around in Stanton include the Tina and Pacific neighborhood, the Benedict tract, Stanton Town Center.

ADU Contractor in Stanton 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 Stanton?
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 Stanton the application goes to the City of Stanton Building Division within the Community and Economic Development 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.
