Irwindale is a small city with an outsized industrial footprint — quarries, materials operations, warehouses, and commercial sites define much of the landscape, with a compact residential community woven between them. Contractors here spend more time on commercial and industrial buildings than anywhere else in the San Gabriel Valley, and the work demands a crew comfortable with that environment.
Industrial and commercial projects live or die on their mechanical systems: process plumbing, gas lines, heavy-duty HVAC, and drainage that has to work the first time. Mars Construction Industries Corp holds four CSLB classifications in-house — A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC) — so the same accountable team handles the building, the pipes, and the air. For Irwindale’s business owners, that means one contract and one schedule instead of a chain of specialty subs.
Construction & Remodeling Services in Irwindale, CA
Our commercial and industrial work covers tenant improvements, office buildouts, warehouse and light-industrial interiors, and restaurant projects. We self-perform plumbing — including gas lines and commercial-grade fixtures — and HVAC install and replacement with our own licensed crews, which keeps quality control and scheduling under one roof. For operating facilities, we phase work to minimize downtime.
Irwindale’s residential base may be small, but its homes get the same full-service treatment: kitchen and bath remodels, additions, repipes for aging systems, and HVAC replacement. Our 911 Drain Lines division handles sewer camera inspection, hydro jetting, and trenchless repair — with a 20-year warranty on sewer lining — for both homes and commercial properties.
We also build ADUs. Through our sister brand ADU Cities, we’ve delivered more than 100 accessory dwelling units in four years, giving Irwindale homeowners a way to add housing on their lots with one team handling design coordination through final finishes.

Why Irwindale Property Owners Choose Mars
Industrial cities don’t tolerate excuses. Here’s the accountability model Irwindale property owners get:
Mars Construction Industries Corp is a general contractor backed by 30+ years of hands-on experience, based in Orange, California. We are licensed, bonded, and insured, holding four CSLB classifications in-house under license #1138550: A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC). We are also SB-PW and SB(Micro) certified.
That means one accountable team. Most projects cross trades, and that is where jobs stall — the plumber blames the framer, and you are left managing people who do not work for you. With Mars, the general contractor, the plumbing crew, and the HVAC crew are the same company: one estimate, one schedule, one phone number, and no gaps between trades.

Frequently Asked Questions
Is Mars Construction Industries Corp licensed for this work?
Yes. We operate under CSLB license #1138550 with four classifications in-house: A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC). We are licensed, bonded, and insured, and we hold SB-PW and SB(Micro) small-business certifications. You can verify any contractor’s license status through the Contractors State License Board before you sign anything — and you should.
Do you work on industrial or warehouse buildings, or just offices and homes?
We handle warehouse and light-industrial interiors in addition to offices, retail, restaurants, and homes — general construction plus in-house plumbing and HVAC. Walk us through your facility and we’ll tell you plainly what we can take on.
Can you work around our operating hours?
Yes. For operating businesses and facilities, we phase the work — nights, weekends, or section by section — so downtime stays minimal. We settle the plan during the walkthrough before anything is scheduled.
Do you do commercial and tenant improvement work?
Yes. We build out offices, retail spaces, restaurants, and light industrial interiors, and we handle the plumbing and HVAC scope in-house rather than handing it off. For operating businesses, we plan the work in phases so you can stay open while we build.
