La Habra Heights is deliberately rural — large hillside lots, equestrian properties, avocado groves, and ranch-style homes, all of it protected by a community that chose country living over suburban density. Projects here look different from anywhere else in the county: bigger properties, outbuildings, and homes that need room to breathe.
Large rural properties reward a contractor that can handle the full spread. A La Habra Heights project might include a main-house remodel, a barn or workshop, and plumbing and HVAC extended across a big lot — and coordinating separate trades across that kind of property gets expensive fast. 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 covers the house, the outbuildings, and everything connecting them.
Construction & Remodeling Services in La Habra Heights, CA
Our residential work in La Habra Heights covers whole-home remodels, room additions, and high-quality kitchen and bath renovations for the city’s ranch and custom homes. Many properties here are older and ready for full mechanical renewal — complete repipes, sewer line inspection and repair, and HVAC replacement — which we perform with our own licensed crews.
Outbuildings are a big part of life here, and they’re a big part of our work: barns, workshops, tack rooms, and guest houses, built or renovated with proper plumbing, drainage, and climate control. Our A (General Engineering) classification covers the structural and site-work side, so grading-adjacent and foundation work stays in-house.
For multigenerational families, our sister brand ADU Cities has delivered more than 100 accessory dwelling units in four years — detached units and conversions that fit naturally on large rural lots. And 911 Drain Lines handles drain and sewer work across the property, with camera inspection, hydro jetting, trenchless repair, and a 20-year warranty on sewer lining.

Why La Habra Heights Property Owners Choose Mars
Rural hillside properties need a contractor with range. Here’s the one-team model La Habra Heights 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 barns and outbuildings, or only houses?
We build and renovate barns, workshops, tack rooms, and guest houses — plumbing, drainage, HVAC, and general construction — with the same team that works on the main residence. One contract can cover the whole property.
Our property is large with older systems. Where do we start?
With a walkthrough of the whole property — house and outbuildings. We’ll map out what the plumbing, sewer, and HVAC systems need alongside any remodel goals, and put it in one written proposal so you can prioritize with real information instead of guesses.
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.
