#1 ADU Contractor in Palm Springs
Custom Builds by Horizon Remodeling

Horizon Construction & Remodeling Inc. handles ADU construction in Palm Springs from early planning through final inspection, coordinating design, permitting, and every trade involved in the build. The City of Palm Springs Building Safety Department reviews and issues permits for this work, and properties carrying a historic designation may also need a Certificate of Appropriateness before exterior changes can move forward, which matters in neighborhoods like Racquet Club Estates, Twin Palms, and Vista Las Palmas where mid-century modern homes are common. We manage that process for you.

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 Palm Springs means understanding a legal framework that has been moving fast at the state level. California consolidated its ADU rules into Government Code sections 66310 through 66342 in 2024, and another round of changes took effect January 1, 2026. Under the current law, square footage is calculated as interior livable space rather than total footprint. Once you submit an application, the reviewing agency has 15 business days to determine whether it is complete and 60 days to approve or deny it. Approval is ministerial, meaning no public hearing and no discretionary design review stands between you and a decision.

In Palm Springs, that application goes to the City of Palm Springs Building Safety Department. One factor that can add a step for some owners is historic classification. Properties designated as Class 1 or Class 2 historic resources must obtain a Certificate of Appropriateness before any exterior alteration or demolition proceeds. That determination is made by the Historic Site Preservation Board or the Historic Preservation Officer. Work confined entirely to the interior is exempt from that requirement.

The historic layer matters more here than in most Southern California cities. Palm Springs was built heavily between the late 1940s and the mid 1960s, and the Alexander Construction Company alone contributed roughly 2,200 homes, effectively doubling the city’s housing stock during that period. Many of those homes now carry historic designations, so confirming your property’s classification early keeps the project on schedule.

The dominant housing type in Palm Springs also shapes where a detached ADU can realistically sit. The mid century modern post and beam houses common across neighborhoods like Racquet Club Estates, Twin Palms, Vista Las Palmas, and Deepwell Estates typically feature low slope roofs, deep overhangs, floor to ceiling glass, and a compact kitchen positioned behind the main living area. That layout affects sightlines, utility run distances, and how a new structure relates to the primary building on the lot.

State law preempts any local or county provision that conflicts with Government Code sections 66310 through 66342, so what a county handout describes as the allowable scope is not always what the law actually permits. We read the current statute alongside your specific parcel conditions before any design work begins, which keeps your project grounded in what you are actually entitled to build rather than an outdated interpretation.

Why Choose Horizon Remodeling As Your ADU Contractor in Palm Springs ?

Horizon Construction and Remodeling builds ADUs throughout Palm Springs as a licensed Class B general building contractor, bonded, with more than 15 years of design-build work behind us. One company draws the plan, coordinates it through the City of Palm Springs Building Safety Department, and builds the finished unit. That single point of accountability matters in a city where the permit path can carry additional steps depending on how your property is classified.

Palm Springs has a large number of mid-century modern homes, many dating to the Alexander Construction Company era of the late 1940s through mid 1960s, and properties in neighborhoods like Racquet Club Estates, Twin Palms, Vista Las Palmas, and Deepwell Estates may carry a Class 1 or Class 2 historic resource designation. When that applies, exterior alterations typically require a Certificate of Appropriateness before the Building Safety Department will issue permits. We plan around that requirement from the start rather than discovering it mid-project.

A few state-level protections apply to every ADU regardless of local conditions: no owner-occupancy requirement, 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 also factor in desert-specific site considerations, including summer heat loads, wind design requirements, and whether the parcel sits within a flood hazard or environmental constraint area.

ADU Contractor in Palm Springs FAQ

What is an ADU and why should I build one?

An accessory dwelling unit is a self-contained secondary residence on your existing property, whether that takes the form of a converted garage, a detached backyard structure, or an attached suite. Building an ADU with Horizon Construction and Remodeling can generate rental income, house extended family, or simply add usable square footage to a Palm Springs property.

ADU costs in Palm Springs vary based on factors we cannot assess from a web page alone. The size and type of unit matter, as does whether the project is a conversion of an existing space or new detached construction. Site conditions, utility runs across your lot, and the finish level you select all pull the budget in different directions. What we can explain is where the money typically goes and what state law shields 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. 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 force a fire sprinkler retrofit of your existing home.

Before we quote anything, we walk the property, confirm setbacks, and review the utility situation. Many Palm Springs homes were built between the late 1940s and the mid 1960s, and permits go through the City of Palm Springs Building Safety Department, which adds steps we account for before finalizing scope and price. If your property carries a Class 1 or Class 2 historic designation, a Certificate of Appropriateness may be required before exterior work begins, so we verify that status early. Anyone offering a firm number before seeing the parcel is guessing. One point worth repeating: the CalHFA ADU grant program is closed and fully allocated, and the agency itself warns that anyone claiming to help you obtain that grant is running a scam.

An ADU always requires a building permit, and in Palm Springs that application goes to the City of Palm Springs Building Safety Department. Approval is ministerial rather than discretionary, meaning there is no hearing and no design review board to satisfy. State law sets a 60-day window to approve or deny, with a pre-approved plan cutting that to 30 days. One thing to keep in mind: if your property carries a Class 1 or Class 2 historic designation, a Certificate of Appropriateness may be required before exterior work begins. Horizon prepares the permit package, submits it, and sees the project through inspections so that responsibility never falls back on you.

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.
