La Verne blends a historic small-town core — tree-lined streets near the university, early-20th-century homes — with foothill neighborhoods of ranch houses looking out over the valley. It’s a college town with deep roots, where homeowners tend to invest in their properties for the long haul rather than flipping them.
Long-haul ownership is exactly when a multi-trade contractor pays off. Renovating a historic La Verne home means updating plumbing and HVAC behind the walls while respecting the architecture; adding to a foothill ranch means structural work plus extended mechanical systems. Mars Construction Industries Corp holds four CSLB classifications in-house — A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC) — so one accountable team handles the structure, the pipes, and the air.
Construction & Remodeling Services in La Verne, CA
In La Verne’s historic neighborhoods, we renovate older homes with care — kitchen and bath remodels, additions that match the original architecture, and full mechanical updates. Many of these homes are due for repipes and sewer lateral attention, which our own C-36 crews and 911 Drain Lines division handle: camera inspection, hydro jetting, and trenchless repair with a 20-year warranty on lining.
In the foothill neighborhoods, the work runs toward whole-home renovations, room additions with views, and HVAC systems sized for larger homes and warmer hillside exposures. Our A (General Engineering) classification covers structural and site work, keeping retaining, drainage, and foundation-adjacent construction in-house.
ADUs fit La Verne well — for university-area rentals or multigenerational family space. Through our sister brand ADU Cities, we’ve delivered more than 100 accessory dwelling units in four years, built start to finish by the same team that handles the main house.

Why La Verne Property Owners Choose Mars
La Verne homeowners plan in decades, not years. Here’s the long-view model we bring:
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.
Proudly Serving La Verne and Los Angeles County
La Verne sits in Los Angeles County, and we serve it regularly from our Orange County home base. We serve La Verne and the surrounding foothill and San Gabriel Valley communities — Claremont, San Dimas, Pomona, and beyond — working across Los Angeles County.
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.
Our home is historic. Will renovation damage its character?
Not if it’s done right. We match rooflines, trim, and architectural details on additions, and we concentrate modernization where it belongs — plumbing, HVAC, kitchens, baths, and floor plans. The street sees the same house; you live in a better one.
Do you handle the structural side of hillside or foothill projects?
Yes. Our A (General Engineering) classification covers structural and site work, so retaining, drainage, and foundation-adjacent construction stays with our own team instead of a separate contractor.
Do you subcontract everything out?
No. We self-perform across our four licensed classifications — general construction, plumbing, drain and sewer, and HVAC — which covers the bulk of most residential and commercial projects. For work outside our classifications, such as electrical, we coordinate properly licensed subcontractors and stay accountable for their work as your general contractor. You still deal with one team.
