Twentynine Palms is the high desert — gateway to Joshua Tree, big skies, rural lots, and a mix of longtime desert residents, military families from the Marine base, and a growing wave of short-term rental owners. Building and remodeling out here has its own rules: extreme heat, freezing winter nights, well and septic systems on many properties, and homes ranging from vintage desert cabins to newer builds. A contractor working in 29 Palms needs desert experience and multiple trades under one roof, because the nearest specialist for the next trade might be an hour away. Mars Construction Industries Corp brings four licenses in-house — construction, plumbing, drain/sewer, and HVAC — so your desert project doesn’t depend on a relay of subcontractors driving in from three counties.
Construction & Remodeling Services in Twentynine Palms, CA
HVAC is the defining system in the high desert. Summer temperatures regularly top 100 degrees and winter nights drop near freezing, which means heating and cooling equipment works harder here than almost anywhere in Southern California. We install, replace, and repair full HVAC systems — and we size them for desert reality, not catalog averages. If your system can’t keep up in August or short-cycles through winter, our C-20 licensed team diagnoses it honestly and fixes it right.
Remodeling in 29 Palms splits two ways. Vintage desert cabins and older homes get practical, durable updates: kitchens and baths rebuilt with materials that handle temperature swings, repipes where old supply lines have failed, and water heater replacements. Newer homes and short-term rentals get the guest-ready treatment: refreshed kitchens and baths, durable flooring, outdoor spaces with fire features and gas lines run by our own C-36 plumbers. Many desert properties run on septic systems, and our drain and sewer expertise — camera inspections, hydro jetting, and repair through 911 Drain Lines — applies to keeping those systems healthy too.
We also build additions and ADUs on the area’s generous rural lots. A detached casita for guests, a rental unit, or extra space for a growing household — through our sister brand ADU Cities we’ve built more than 100 ADUs in four years. Our A (General Engineering) license covers the structural and site work that rural desert builds often require.

Frequently Asked Questions
Are you a licensed contractor?
Yes. Mars Construction Industries Corp is CSLB #1138550, holding A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC). Licensed, bonded, and insured, with SB-PW and SB(Micro) certifications.
Do you work in the high desert?
Yes. We serve Twentynine Palms and the Morongo Basin as part of our San Bernardino County service area. Desert HVAC, rural-lot additions, and ADUs are all core capabilities.
My AC can’t keep up with the heat. Can you help?
Yes. We diagnose underperforming systems honestly — sometimes it’s maintenance or ductwork, sometimes it’s a system that was never sized for desert loads — and our C-20 team installs, replaces, and repairs full HVAC systems.
Which trades do you keep in-house?
General construction, plumbing, drain and sewer, and HVAC — all under our own licenses. Work outside those classifications, such as electrical contracting, is handled by licensed specialty subcontractors we manage.
Can you build an ADU or casita on a rural lot?
In many cases, yes. Through ADU Cities we’ve built more than 100 ADUs in four years, and the Morongo Basin’s larger lots are often well suited to detached units.
Do you handle drain and septic-related issues?
We handle drain and sewer diagnostics and repair — camera inspections, hydro jetting, and trenchless repair with a 20-year lining warranty — through 911 Drain Lines, 24/7 at 714.746.7611.
