Does Desert Hot Springs have zoning, lot-size rules and setbacks?
Desert Hot Springs has city zoning, and the Planning Division identifies the applicable land-use and development standards for each property’s zoning district.37 The ordinary single-family minimum lot size is 5 acres in R-RD Residential Rural Desert and 7,200 square feet in R-L Residential Low; the code also provides separate SB 9 standards.4 R-RD standard setbacks are 50 feet from the public right-of-way, 50 feet at the interior side and 100 feet at the rear; R-L standards are 15, 5 and 20 feet respectively, subject to applicable table notes and exceptions.5 Standard maximum lot coverage is 15% in R-RD and 40% in R-L, with separate SB 9 provisions.12 Ask City Planning to check the district and applicable exceptions before choosing a building footprint.7
How do septic permits and water wells work inside Desert Hot Springs?
We could not confirm which office issues septic approvals for parcels inside Desert Hot Springs; ask Riverside County Environmental Health’s Indio Land Use office at (760) 863-7570 to establish jurisdiction before commissioning a septic design.6 The county’s OWTS Construction Application rule covers unincorporated Riverside County and contracted cities, so city coverage needs confirmation for your address.13 California’s onsite wastewater policy authorizes local agencies to issue OWTS permits; that statewide framework does not identify the city’s permitting office.14 Water wells have a clearer countywide rule: Riverside County Environmental Health requires a permit for well construction, reconstruction or destruction throughout the county, with a Registered Well Driller preparing the application for construction or destruction.9
Can you live in an RV or tiny home in Desert Hot Springs?
We could not confirm a general rule allowing residential RV occupancy, temporary camping or tiny-home occupancy on private land inside Desert Hot Springs; ask City Planning about the proposed dwelling and use before relying on either as housing during construction.7 In R-RD, the detached single-family minimum dwelling size is 1,000 square feet, with a 900-square-foot Discount Zone standard and a separate 800-square-foot SB 9 standard.8 A manufactured home cannot be newly installed in a permitted residential district if more than 10 completed years have elapsed since manufacture; already-installed older manufactured homes are unaffected by that subsection.15 These dwelling standards do not establish permission to occupy an RV.815
Building a home in Desert Hot Springs: what should you do first?
