The City of Industry is almost entirely commercial and industrial — warehouses, distribution centers, manufacturing, and retail corridors, with very few residents. That makes the contractor equation different here: you’re not hiring someone for a kitchen remodel, you’re hiring a team that can keep a facility running. Tenant improvements, warehouse plumbing, industrial-scale HVAC, sewer lines serving commercial buildings, and buildouts on aggressive timelines. Mars Construction Industries Corp is built for that kind of work — a licensed general contractor with plumbing, drain/sewer, and HVAC trades in-house, so a commercial project doesn’t stall in the gap between separate contractors.
Commercial Construction & Tenant Improvement in the City of Industry, CA
Industrial and commercial properties live or die on uptime. When a warehouse needs new restrooms, a distribution center needs its HVAC replaced, or a retail space needs a full tenant improvement before a lease commencement date, the critical factor is coordination. Mars holds A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC licenses in-house under CSLB #1138550. On a TI buildout, that means our own crews handle the demolition and framing, the plumbing rough-in, and the mechanical work — sequenced by one superintendent, accountable to one contract.
Our C-36 plumbing license covers commercial water heaters, repipes, gas lines, and restroom buildouts. Our C-20 covers commercial HVAC installation, replacement, and repair — rooftop units, split systems, and ventilation for industrial spaces. And through 911 Drain Lines, we handle commercial drain and sewer: camera inspections, hydro jetting for grease and buildup in restaurant and food-service lines, and trenchless sewer repair with a 20-year warranty on lining, which matters enormously when the alternative is excavating a parking lot or warehouse slab.
We also do ground-up commercial construction and additions under our A and B licenses — structural work, site concrete, and building expansions. Mars brings 30+ years of hands-on experience, is licensed, bonded, and insured, and carries SB-PW and SB(Micro) small-business certifications, which can matter for projects with public-agency or corporate diversity requirements.

Why City of Industry Property Owners and Managers Choose Mars
Commercial projects fail in the handoffs. The GC blames the plumber, the plumber blames the HVAC contractor, and the opening date slips. Our model eliminates that: four licenses, one company, one point of accountability. When the plumbing, the mechanical, and the structure are all ours, scheduling is a plan instead of a negotiation — and when something needs attention at 2 AM, 911 Drain Lines answers.
Mars Construction Industries Corp, CSLB #1138550, licensed, bonded, and insured — backed by 30+ years of hands-on experience. SB-PW and SB(Micro) certified. Sister brands include 911 Drain Lines, ADU Cities, Get Your Roof Certified, and Universal Inspect.
