Riverside is the Inland Empire’s historic and civic center — the Mission Inn downtown, the Wood Streets’ classic homes, university neighborhoods, and a government and business core keeping the commercial market active. A 1920s bungalow, a downtown office building, and a student rental can sit within a mile of each other, each needing a different kind of contractor. Or one contractor with the range for all three.
Mars Construction Industries Corp has that range, 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) — so we can repipe a Wood Streets historic, build out a downtown office, and renovate a rental near the universities, all with our own licensed crews. One estimate, one project manager, one accountable team: licensed, bonded, and insured.
Construction & Remodeling Services in Riverside, CA
Riverside’s older neighborhoods are where our diagnostic approach pays off. We camera-inspect sewer laterals in the city’s early-20th-century housing stock — clay and cast-iron lines that have served for generations — and our C-36 crews handle whole-home repipes, water heaters, and gas lines as coordinated projects. When a lateral is failing under a mature street tree, trenchless lining with our 20-year warranty renews it without destroying the landscaping. Downtown brings steady TI work — offices, retail, restaurant build-outs — where in-house plumbing and HVAC keep restroom rough-in and mechanical scopes on schedule, with the bonding and insurance commercial clients require.
The university areas add a third dimension: rental and investment properties where durable systems beat pretty finishes. Unit-turn renovations, building-wide repipes, drain maintenance — backed by 911 Drain Lines’ 24/7 emergency response at 714.746.7611. And through ADU Cities (100+ in four years) we build detached units and garage conversions that make strong sense in Riverside’s rental market.

Why Riverside Property Owners Choose Mars
Every property owner eventually chooses: manage a patchwork of trade contractors yourself, or hire one general contractor who owns the whole result. Backed by 30+ years of hands-on experience, Mars Construction Industries Corp has been the second kind — a licensed, bonded, and insured GC (CSLB #1138550) headquartered in Orange, California, holding four licenses in-house: A General Engineering, B General Building, C-36 Plumbing, C-20 HVAC.
Real projects are never single-trade. A bath remodel is plumbing, carpentry, and HVAC; an addition is engineering, building, plumbing, and mechanical. When one company holds all four licenses, there’s no seam for problems to hide in. You get one estimate, one schedule, and one project manager who answers for everything.
Our SB-PW and SB(Micro) certifications reflect the discipline we bring to the job site. And our sister brands — 911 Drain Lines, ADU Cities, Get Your Roof Certified, Universal Inspect — let us serve Riverside County properties end to end, from emergency drain calls to full ADU builds. When a sewer line needs lining, we back it with a 20-year warranty. That’s the accountability Riverside keeps hiring us for.

Frequently Asked Questions
How does your estimate process work?
Call 310.880.9718 or email brett@marsx.construction. We’ll walk the property, look at actual conditions, and give you a detailed written estimate spelling out scope, materials, and expectations. No pressure, no vague allowances — you know exactly what you’re buying before work starts.
Can you build an ADU on my property?
Yes — through ADU Cities we’ve built 100+ ADUs in four years. Design, permitting support, and construction in one design-build package: garage conversions, detached units, and attached additions.
Will I deal with several contractors?
No — that’s the point of hiring us. One project manager, one schedule, one company accountable for the finished work. Most projects never need an outside trade; when they do, we coordinate them.
We own rental property near the universities. Do you work with landlords and investors?
Regularly. Unit-turn renovations, building-wide repipes, water heater replacements, and drain programs — planned to minimize vacancy time. And 911 Drain Lines gives your tenants 24/7 emergency plumbing response at 714.746.7611. One vendor for capital projects and emergencies keeps management simple.
