Whether you want to add a casita, convert a garage or sell a home that already has an extra unit, you need to know which rules apply in La Quinta. This guide explains how zoning and accessory dwelling unit (ADU) rules work for a La Quinta homeowner, which parts come from California state law, and where the city’s own zoning code and staff fit in.

How zoning works in La Quinta
The Planning Division guides growth and the preservation of existing neighborhoods, and it will discuss development proposals or use permits on request. The Zoning Code is posted on the city website, and the city’s General Plan 2035 sets the long-range framework.
Planning applications, like building permits, are submitted through the HUB Online Portal. Many La Quinta neighborhoods are also governed by a homeowner association or specific plan with its own architectural rules, which are separate from city zoning.
What California state law says about ADUs
La Quinta’s ordinance has to follow California’s ADU statutes. The California Department of Housing and Community Development (HCD) summarizes the main limits. Treat these as the baseline and confirm exact numbers with the city, because the city’s code can add design standards where state law allows.
- Ministerial approval: a compliant ADU or junior ADU application must be approved or denied without a discretionary hearing, within 60 days of a complete application when there is an existing single-family home.
- Size: state law guarantees that an ADU of at least 800 square feet and 16 feet tall can be built, and local rules cannot set a minimum size that blocks an efficiency unit.
- Setbacks: no more than four feet from the side and rear lot lines, and no setback for a conversion of existing space.
- Junior ADU: up to 500 square feet inside an existing single-family home, with an efficiency kitchen and the owner living in the home or the JADU.
- Parking: cities cannot require replacement parking when a garage is converted, and many ADUs are parking-exempt in specified cases such as proximity to transit.
- Fees and rentals: state law limits impact fees on small ADUs, and rentals must be for terms longer than 30 days.
Patio covers, sheds and other accessory structures
The Building Division’s FAQ says a freestanding patio cover up to 120 square feet of roof area and a one-story detached shed up to 120 square feet of floor area are exempt from building permits.
They still must meet the city’s setback rules and any association approval, and an attached patio cover or a larger structure needs a permit. These small structures are not ADUs. Anything with sleeping, cooking and sanitation facilities is treated as a dwelling unit and falls under the ADU rules.
Steps to add an ADU in La Quinta
1. Confirm your lot and any HOA rules
Check zoning, lot lines, easements, utilities and association restrictions. In the Cove, a septic system may need to be converted to sewer through the Coachella Valley Water District before a building permit can be issued.
2. Call the Planning Division
Ask Planning for the current ADU standards in Section 9.60.090 and for any handout or pre-approved plans the city offers.
3. Prepare plans
Work with a licensed designer or architect. Plans need to show setbacks, height, floor area, utilities and the relationship to the main house.
4. Apply in the HUB Online Portal
Submit the application electronically. The city does not accept in-person submittals at this time, and you can track status and receive email notices.
5. Build and pass inspections
Schedule inspections with the Building Division at (760) 777-7000, and keep the final inspection record. A final is what makes the unit legal for a future sale.
Selling a La Quinta home with an ADU or casita
A permitted ADU can be a selling point, but an unpermitted one can slow a sale. Appraisers and lenders usually count only permitted living space. Gather the permit, plans, final inspection and any rental records. Remember that an ADU generally cannot be sold separately from the main home unless state law specifically allows it.
How to sell a house in La Quinta with an unpermitted unit
- Find out what exists. Ask the Building Division what permits are on file for the address.
- Check whether it can be legalized. Planning can tell you whether the unit meets current ADU standards.
- Estimate cost and time. Include design, permit fees, corrections and the months it takes.
- Compare with an as-is sale. A cash buyer can purchase the home with the unit as it is.
- Disclose. Known unpermitted work must be disclosed to buyers.

Where are La Quinta’s ADU rules written?
The city’s ADU ordinance is in Section 9.60.090 of the Municipal Code, according to the city’s housing element draft, and it must follow California Government Code Section 65852.2. Call the Planning Division at (760) 777-7023 for the current standards.
Can I build an ADU on any La Quinta lot?
State law requires cities to allow ADUs on residential lots with an existing or proposed home, subject to objective standards. Lot conditions, utilities and HOA rules still affect what you can build, so check with Planning first.
How long does the city have to review an ADU application?
Under California law, a compliant ADU application on a lot with an existing single-family home must be acted on within 60 days of a complete application.
Is a backyard shed the same as an ADU?
No. The city exempts one-story detached sheds up to 120 square feet from building permits, but a structure with sleeping, cooking and sanitation facilities is a dwelling unit.
Where do I submit zoning and building applications?
Through the HUB Online Portal. The city says applications cannot be submitted in person at this time.
Can I sell a La Quinta house that has an unpermitted casita or ADU?
Yes. You can sell as-is to a cash buyer without legalizing the unit first, but you must disclose known unpermitted work.
