Santa Ana is Orange County’s urban heart — the county seat, a historic downtown in renaissance, landmark neighborhoods like Floral Park, and a commercial density no other OC city matches. The needs are as varied as the city: historic-home renovations, downtown office and retail build-outs, multifamily upgrades, restaurants along corridors that never sit still.
A contractor who only does one of those things is a bottleneck in Santa Ana. Mars Construction Industries Corp is a genuine multi-trade contractor backed by 30+ years of hands-on experience: four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, C-20 HVAC (Lic. #1138550). Residential or commercial, historic or brand-new — one licensed, bonded, and insured team, one estimate, one project manager.
Construction & Remodeling Services in Santa Ana, CA
Downtown and the commercial districts keep our TI division busy: office build-outs, retail interiors, restaurant projects where schedule is everything. Our C-36 crews handle restroom rough-in, kitchen plumbing, and gas lines for restaurant builds; our C-20 crews handle rooftop and split-system HVAC. Both scopes are ours — not a subcontractor’s — so TI timelines stay under our control, and we carry the licensing, bonding, and insurance commercial landlords require. In the historic neighborhoods, the work is more surgical: repipes routed around original finishes, camera inspections revealing decades-old laterals, trenchless lining with a 20-year warranty that avoids excavating established streetscapes.
Multifamily and investment properties are a third pillar — unit-turn renovations, common-area plumbing, water heater replacements at scale, and drain maintenance programs. Through 911 Drain Lines we provide 24/7 emergency response at 714.746.7611, which property managers in a dense urban market genuinely need. Kitchen and bath remodels in the historic districts balance modern function with architectural respect.

Why Santa Ana Property Owners Choose Mars
The classic remodeling horror story goes like this: three contractors, three schedules, and nobody responsible when something goes wrong. We’re the opposite of that. Mars Construction Industries Corp is licensed, bonded, and insured (CSLB #1138550), backed by 30+ years of hands-on experience, and we hold four trade licenses in-house — A General Engineering, B General Building, C-36 Plumbing, C-20 HVAC — so most of your project never leaves our own crews.
That changes the experience: the company that bids your kitchen remodel also moves the gas line, sizes the HVAC for the new floor plan, and handles the structural work. No finger-pointing between subs, no stacked mystery markups, no waiting weeks for a trade contractor to fit you in.
We’re based in Orange, California, and carry SB-PW and SB(Micro) certifications. Through 911 Drain Lines, ADU Cities, Get Your Roof Certified, and Universal Inspect, we serve a property end to end — from the sewer lateral (our trenchless lining has a 20-year warranty) to the roof. Santa Ana hires us because one accountable team is simply easier, and the work turns out better.

Frequently Asked Questions
Do you take on commercial work?
Absolutely — offices, retail, restaurants, and light industrial/warehouse interiors. We’re licensed, bonded, and insured for commercial work with SB-PW and SB(Micro) certifications, and in-house plumbing and HVAC keep TI schedules tight.
Are you licensed to do this work?
Yes. Mars Construction Industries Corp holds CSLB #1138550 — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC. We’re licensed, bonded, and insured, with SB-PW and SB(Micro) certifications. Verify any California contractor at cslb.ca.gov — we encourage it.
Do you handle every trade in-house?
The trades that matter most — building, plumbing, HVAC — are our own licensed crews under CSLB #1138550. For specialty scopes outside our four licenses, we bring in vetted specialists and manage them. Either way, you deal with one accountable team and one point of contact.
We manage commercial property in Santa Ana. Can one contractor handle TI work and plumbing emergencies?
Yes — a combination we serve often. Our commercial division handles tenant improvements and build-outs, our C-36 crews handle the mechanical and plumbing scopes within them, and 911 Drain Lines provides 24/7 emergency drain and plumbing response at 714.746.7611.
