Rolling Hills is one of the most distinctive communities in Los Angeles County — a gated, equestrian city of large estates on big lots, where homes sit back from quiet roads and many properties include room for horses. The housing here is estate-scale: ranch-style homes, custom builds, and properties where a renovation can mean a whole-house transformation, a guest house, or an addition sized for multigenerational family. Projects at this scale punish the multi-contractor approach — when the framing crew, the plumber, and the HVAC contractor are three separate companies, coordination failures land on the homeowner. An estate project needs one team accountable for all of it.
Mars Construction Industries Corp is a multi-trade general contractor based in Orange, CA, operating with 30+ years of hands-on experience. We hold four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC (CSLB #1138550) — so the same team handles your construction, plumbing, drain and sewer work, and HVAC under one contract. For Rolling Hills estate owners, that means one point of responsibility across the entire property.
Construction & Remodeling Services in Rolling Hills, CA
Our Rolling Hills work centers on whole-home remodels and large-scale renovations — the kind of project where a homeowner wants the entire house brought up to current standards of comfort and finish in one coordinated effort. Because we hold our plumbing, drain, and HVAC licenses in-house, that effort includes repipes, new water heaters, gas line work, and full HVAC replacement as part of the same project plan, sequenced properly instead of stacked awkwardly across subcontractors.
Many estate properties here benefit from additional structures: guest houses and ADUs for family or staff, and outbuildings suited to an equestrian property. Through our sister brand ADU Cities, we’ve built more than 100 ADUs in four years, and we handle detached guest units as part of a larger property plan. We also handle additions that expand the main house — primary suites, great rooms, and kitchen expansions sized for how the home is actually lived in.
On large lots, infrastructure matters as much as finishes. We provide drain and sewer services including camera inspection, hydro jetting, and trenchless sewer repair, with a 20-year warranty on our sewer lining work — valuable on estate properties where long laterals run under landscaping you don’t want disturbed. And for homes with aging or undersized climate systems, we install and replace HVAC sized for large, multi-zone houses.

Why Rolling Hills Property Owners Choose Mars
Estate work demands a single accountable team, and that’s our model. Four licenses in-house — A, B, C-36, and C-20 — means construction, plumbing, sewer, and HVAC are all performed by us, under one contract, with one team responsible for the outcome. We’ve been operating with 30+ years of hands-on experience, we’re licensed, bonded, and insured (CSLB #1138550), and we’re SB-PW and SB(Micro) certified. On a property of this scale, that eliminates the most common failure in renovation: trades blaming each other while the homeowner pays for the delay. Our sister brands — 911 Drain Lines, ADU Cities, Get Your Roof Certified, and Universal Inspect — extend what one relationship covers.

Frequently Asked Questions
Do I need a licensed contractor for my project?
In California, any construction project totaling $1,000 or more in labor and materials must be performed by a licensed contractor. Always verify licensing on the CSLB website. Ours is CSLB #1138550, covering A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC.
How does your estimate process work for large projects?
We walk the property with you, discuss the full scope — including infrastructure like plumbing, sewer, and HVAC — and provide a written estimate. For estate-scale work, we lay out the sequence of trades so you can see how the project flows from rough work to finishes.
Can you add a guest house or ADU to my property?
Yes. We build ADUs and guest houses, and through our sister brand ADU Cities we’ve completed more than 100 ADUs in four years. We can plan a detached unit as part of a larger property renovation.
Which trades do you handle in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC — all under our own CSLB licenses. Electrical work is performed by qualified licensed electricians we bring in, since we do not hold the C-10 electrical classification.
Do you handle plumbing or sewer emergencies?
Yes. Our sister brand 911 Drain Lines provides 24/7 drain and plumbing emergency service at 714.746.7611.
