Commerce is industry and entertainment side by side — manufacturing, warehousing, and distribution along the rail corridors, plus the casino and retail draws along Telegraph Road. With almost no residential base, the construction work here is overwhelmingly commercial: tenant improvements, warehouse and industrial facility work, restaurant and retail buildouts, and the plumbing and mechanical systems that keep commercial buildings operating. Mars Construction Industries Corp serves this market with a commercial-focused, multi-trade operation — A, B, C-36, and C-20 licenses in-house, so a TI project, a rooftop unit replacement, or a sewer repair under a parking lot is handled by one accountable contractor.
Commercial Construction & Tenant Improvement in Commerce, CA
Speed and coordination decide commercial projects. A restaurant buildout on a lease deadline, a warehouse adding restrooms and offices, a retail space turning over between tenants — every one of them needs plumbing, HVAC, and general construction sequenced tightly. Mars self-performs all three: our B-licensed crews handle demolition, framing, and finishes; our C-36 plumbers run water, drain, and gas lines; our C-20 team handles HVAC and ventilation. One superintendent, one schedule, one contract — no waiting on a plumber who answers to a different company.
Commercial drain and sewer is a specialty through 911 Drain Lines. Restaurant grease lines, warehouse floor drains, and aging commercial sewer laterals all get the same treatment: camera inspection to see the real problem, hydro jetting to clear it, and trenchless repair or lining where excavation would shut down operations — our lining carries a 20-year warranty. When a line fails after hours, 911 Drain Lines answers 24/7 at 714.746.7611.
Our C-20 license covers commercial HVAC installation, replacement, and repair — rooftop package units, split systems, exhaust and makeup air for food service, and warehouse ventilation. And under our A (General Engineering) license, we handle structural and site work: building additions, concrete, and facility expansions. Mars brings 30+ years of hands-on experience, licensed, bonded, and insured, with SB-PW and SB(Micro) certifications.

Why Commerce Property Owners and Managers Choose Mars
Downtime is the enemy in Commerce. A kitchen that can’t open, a warehouse without working restrooms, a retail space missing its turnover date — all of it costs money daily. Our in-house trades exist to compress timelines: when the plumber, the HVAC tech, and the framing crew work for the same company, sequencing is a plan, not a negotiation between vendors. That’s the practical advantage of four licenses under one roof.
