Why build an ADU in Palm Desert.
Palm Desert offers strong ADU economics built on the Coachella Valley's seasonal-resident and retirement-driven rental market. Long-term ADU rentals to seasonal residents, working professionals at the medical and resort employers, and family members of golf-community homeowners support steady demand at premium rents. Property values in Palm Desert have appreciated steadily and ADU appraisal lift is meaningful. The 25 ft attached-ADU height allowance opens up room-addition ADU strategies on existing two-story homes. Construction Station builds to desert-climate-appropriate specifications by default — cool roofs, high-performance insulation, properly sized HVAC, and Title 24 compliance tuned to Coachella Valley climate zones — which directly affects both energy bills and long-term tenant satisfaction. We handle the desert-specific design coordination as part of the standard ADU package.
