ADU Company in Palm Springs, CA
Building an ADU in Palm Springs means designing for 115°F summer days, hard desert water, and Mid-Century Modern neighborhoods where the Historic Site Preservation Board reviews every exterior change. We build accessory dwelling units, garage conversions, and home additions across the Coachella Valley floor, with crews dispatched from our Inland Empire office and pricing written in full before any work begins. Call us at (707) 383-5338 to schedule a free estimate.
Why Palm Springs Homes Are Different
The housing stock here is almost entirely single-story Mid-Century Modern tract homes built between the 1950s and 1970s. Slab-on-grade foundations, post-and-beam framing, and flat or butterfly roofs define the typical lot. Most properties have detached carports rather than enclosed garages, which makes them obvious ADU conversion candidates, except when the HSPB classifies that carport as a character-defining feature.
That historic review layer is the single biggest scheduling variable we face. A garage conversion on a non-HSPB property in the Deepwell Estates might clear permits in weeks. The same scope in the Historic Tennis Club neighborhood can sit in design review for months while the board evaluates roofline compatibility and material substitutions.
Climate drives the build specs. Summer highs of 115°F – 120°F push Manual J cooling loads to levels coastal California contractors routinely underestimate. We size HVAC accordingly. Flat and low-slope roofs also complicate California’s Title 24 solar mandate, often requiring structural engineering before panels can be mounted. And Desert Water Agency’s aquifer-fed supply is among the hardest water in Southern California; we spec whole-unit water softeners or inline descalers as standard equipment on every ADU, not as an upsell.
Our Main Palm Springs Services
Most families who call us fall into one of three project types. Each has its own Palm Springs page with neighborhood-specific guidance and pricing.
Home Addition Contractor in Palm Springs
Home additions here typically extend the primary living space rather than build fully detached units, though we do both. Post-and-beam framing from the original 1950s – 1970s construction often requires careful structural integration, especially where butterfly roofs meet new flat-roofed sections. On HSPB properties, we coordinate exterior material palettes with board guidelines before submitting permits. Home Addition Contractor in Palm Springs
Garage Conversion Contractor in Palm Springs
True enclosed garages are scarce in Palm Springs; carport conversions dominate this category. We enclose with insulated wall assemblies rated for desert temperature swings, upgrade electrical to full ADU panel capacity, and address the common slab-elevation mismatch between original carport pads and finished floor heights. HSPB review applies to most visible exterior changes, so we front-load that documentation. Garage Conversion Contractor in Palm Springs
ADU Builders in Palm Springs
Detached ADUs in Palm Springs are overwhelmingly built as income-producing vacation-rental casitas, not in-law suites. That changes the spec: hotel-grade finishes, separate metering, and sound assemblies that satisfy both the City’s STR permitting and guest expectations. We work with prefab partners including Abodu and Cover when lot access and timeline favor factory-built, and stick-build when HSPB review or custom siting requires it. ADU Builders in Palm Springs

FAQs About ADU Company in Palm Springs
Historic Site Preservation Board review adds 6 – 14 weeks to the permitting timeline, depending on backlog and whether your property is individually designated or within a historic district. We submit complete material palettes and renderings upfront to avoid revision rounds. Call (707) 383-5338 and we’ll check your address against the HSPB map during your free estimate.
Yes. We pull all required permits, including Desert Water Agency sewer and water connection approvals, and coordinate the separate electrical utility application with Southern California Edison. The utility work is included in your written price, not billed separately.
Most R-1 and R-2 zoned lots in Palm Springs allow ADUs, but the City’s STR ordinance caps the number of vacation-rental permits per parcel and requires owner-occupancy of either the main house or the ADU. We verify your zoning and STR eligibility before finalizing any design. Call (707) 383-5338 for a compliance check with your free estimate.
