Vernon is a city built for industry — one of the few cities in California with far more jobs than residents, its landscape defined by warehouses, manufacturing plants, food processing, and commercial buildings. There is very little residential construction work here, and that’s the point: Vernon property owners need a contractor built for commercial and industrial projects. Tenant improvements, warehouse build-outs, office renovations, restroom and plumbing upgrades, industrial drain work, and commercial HVAC — these projects combine construction with mechanical trades as a matter of course, and they punish the fragmented approach. A TI that needs plumbing rough-in, drain work, and rooftop HVAC should live under one contract with one team accountable for the schedule.
Mars Construction Industries Corp is a multi-trade general contractor based in Orange, CA, operating with 30+ years of hands-on experience. We hold four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC (CSLB #1138550). One accountable team handles your construction, plumbing, drain and sewer work, and HVAC — the exact combination Vernon’s commercial and industrial buildings demand.
Construction & Remodeling Services in Vernon, CA
Commercial and industrial tenant improvement is our Vernon focus. We handle warehouse improvements, manufacturing and food-processing facility renovations, office build-outs, and retail TI — including the plumbing, drain, and HVAC scopes these projects require. Because our C-36 plumbing and C-20 HVAC licenses are held in-house, restroom build-outs, plumbing rough-in, process-adjacent drain work, and commercial HVAC installation or replacement all stay inside one contract. One team, one schedule, one point of responsibility — which is what keeps business downtime to a minimum.
Our drain and sewer capabilities matter in an industrial city. We provide camera inspection, hydro jetting, and trenchless sewer repair for commercial laterals and building drain systems, with a 20-year warranty on our sewer lining work. For facilities where excavation would disrupt operations, trenchless methods rehabilitate lines with minimal surface disturbance.
We also handle the building-envelope and interior side of commercial work: office renovations, break rooms, interior reconfigurations, and the general construction scope that frames every TI. And our A General Engineering license covers the site and structural-adjacent work that industrial properties sometimes require.

Why Vernon Property Owners Choose Mars
One accountable team is our model, and industrial clients feel it most. Four licenses in-house — A, B, C-36, C-20 — means a project’s construction, plumbing, drain, and HVAC are all performed by us under one contract, with one team responsible for sequencing and schedule. With 30+ years of hands-on experience, we’re licensed, bonded, and insured (CSLB #1138550), and we’re SB-PW and SB(Micro) certified. In a city where downtime costs money, that single point of responsibility is the difference between a project that finishes and a project that drifts. Our sister brands — 911 Drain Lines, ADU Cities, Get Your Roof Certified, and Universal Inspect — extend what one relationship covers.

Frequently Asked Questions
Do I need a licensed contractor for my project?
In California, any construction project totaling $1,000 or more in labor and materials must be performed by a licensed contractor. Verify any license on the CSLB website before hiring. Ours is CSLB #1138550 — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC.
How does your estimate process work for commercial projects?
We walk the facility with you, review the full scope — construction, plumbing, drain, HVAC — and provide a written estimate. For TI work, we plan around your operations to keep downtime to a minimum.
Can you handle plumbing and HVAC inside a tenant improvement?
Yes. Our C-36 plumbing and C-20 HVAC licenses are held in-house, so those scopes are part of the same contract — not separate subs to coordinate. Electrical work is performed by qualified licensed electricians we bring in, since we do not hold the C-10 electrical classification.
Do you handle commercial drain or sewer emergencies?
Yes. Our sister brand 911 Drain Lines provides 24/7 drain and plumbing emergency service at 714.746.7611 for commercial and industrial clients.
Do you do residential work?
Yes — kitchen and bath remodels, additions, repipes, ADUs, and full home renovations — though in Vernon itself, our work is overwhelmingly commercial and industrial.
