Hesperia is high-desert living with room to breathe — larger lots, outbuildings, and a mix of established neighborhoods and newer tracts stretching toward the mountains. The trade-off for all that space is climate: summer heat that works air conditioners to the edge, winter nights cold enough to remind you the furnace matters too, and wind and dust that age exteriors faster than the calendar suggests.
On bigger lots, projects get bigger too — and that is where a multi-license GC pays for itself. A Hesperia addition or ADU means running utilities across real distance, tying new HVAC into existing systems, and building structures that stand up to desert wind. With A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC in-house, we engineer the whole scope instead of handing pieces of it to whoever is available.
Construction & Remodeling Services in Hesperia, CA
Heating and cooling leads the list in the high desert. We install and replace complete HVAC systems built for big temperature swings — cooling that holds up through heat waves and heating that actually shows up on freezing January nights. As a C-20 contractor, we size and install the equipment ourselves and stand behind how it performs.
Space is Hesperia’s other great asset, and we help homeowners use it: room additions, detached ADUs, garage expansions, and shop and outbuilding construction for the toys, tools, and projects that do not fit in the house. Our A-license engineering background matters when structures have to handle desert wind and grading. Kitchens and baths get full remodels, aging plumbing gets repiped, and our 911 Drain Lines crews handle sewer camera inspections, hydro jetting, and trenchless repairs backed by a 20-year lining warranty.

Why Hesperia Property Owners Choose Mars
Most construction projects fall apart in the gaps between trades. The general contractor blames the plumber, the plumber blames the HVAC tech, and the homeowner is left playing referee. Mars Construction Industries Corp was built to eliminate that problem. We have been a licensed general contractor in Southern California backed by 30+ years of hands-on experience, and we hold four CSLB licenses in-house: A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC — CSLB #1138550.
That means one accountable team from the first walkthrough to the final punch list. When your project needs a repipe, a new sewer lateral, and an HVAC changeout in the same week, you make one call and we sequence all of it. No finger-pointing, no scheduling gaps, no “that’s not my trade.”
We are licensed, bonded, and insured, and we carry SB-PW and SB(Micro) small business certifications. Our family of brands — 911 Drain Lines for drain and sewer work, ADU Cities for accessory dwelling units, Get Your Roof Certified, and Universal Inspect for property inspections — means the same company you trust with your remodel can also camera your sewer line, build your ADU, or inspect a property before you buy it.

How does the estimate process work?
It starts with a conversation about what you need. We walk the project, put together a clear written scope, and give you straightforward combined pricing — no buried markups, no vague allowances. Call 310.880.9718 or email brett@marsx.construction and we will set up a time to look at your project.
Which trades do you handle in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC — all under our own CSLB licenses, so one team is accountable for the whole job. If your project also needs electrical work, we coordinate it through licensed C-10 electrical subcontractors and manage them as part of your project.
Do you offer emergency service?
For drain and plumbing emergencies, our 911 Drain Lines team is available 24/7 at 714.746.7611 — camera inspections, hydro jetting, and sewer repairs, day or night.
Can you build an ADU on my property?
In many cases, yes. Through our sister brand ADU Cities, we have built more than 100 ADUs in the last four years, so we know how to evaluate a lot, design to the space, and build it right.
Do you take on commercial work?
Yes. We handle commercial and tenant improvement projects — office and retail buildouts, restaurant plumbing, and multi-trade renovations — with the same single-point accountability we bring to residential work.
