ADU Regulations in Palm Springs, California

Zoning

Allowed ADU Types

Palm Springs has active short-term rental (STR) regulations that significantly affect ADU use. STR permits for ADUs in residential zones require separate licensing and are subject to city STR caps and neighborhood permit limits. Homeowners intending to use an ADU for vacation rental must obtain an STR permit before operating. Long-term ADU rentals (30+ days) serve the hospitality, healthcare, and resort services workforce and are unrestricted.

Dimensions

Size & Setback Requirements

Setbacks

Palm Springs' R-1-A, R-1-B, and R-1-C zones have varying minimum lot sizes and base development standards. The desert climate and many midcentury modern homes may impose historic or architectural overlay requirements in designated preservation areas. Pool equipment, HVAC, and mechanical setbacks should be coordinated with ADU siting in smaller lots.

Permitting

Permit Process

Palm Springs permitting is handled by Planning Services. Applicants intending to use the ADU as a short-term vacation rental must apply for an STR permit separately; STR permits are subject to city caps and may not be available in all neighborhoods. STR regulations are actively enforced. Historic district or architectural overlay areas may require design review approval.

ADU Costs in Palm Springs

Palm Springs ADU rental income depends heavily on intended use. Long-term rentals (30+ days) serve the resort city's large hospitality and services workforce at $1,500–$2,500/mo. Short-term vacation rentals require a separate STR permit and can generate substantially higher nightly revenue but are subject to city caps and seasonal demand swings. Desert construction costs include premium HVAC and insulation requirements.
