Beverly Hills sets the standard for residential construction in Southern California — architecturally significant estates, exacting expectations, and projects where discretion matters as much as craftsmanship. Homeowners here have seen every kind of contractor, and they know the difference between a company that manages complexity and one that just talks about it.
High-end work is multi-trade by definition. A Beverly Hills whole-home renovation touches structure, plumbing, HVAC, and site work simultaneously, and the coordination burden is where luxury projects usually bleed money and time. We hold the A, B, C-36, and C-20 licenses in-house, which means the estate’s repipe, the new HVAC plant, and the structural changes are planned and sequenced by one accountable team — with a single point of contact who answers the phone.
Construction & Remodeling Services in Beverly Hills, CA
We handle luxury kitchen and bathroom renovations, whole-home remodels, and additions at the level this market expects: detailed scopes, protected finishes, clean jobsites, and trade sequencing that keeps the project moving. Our in-house C-36 plumbers manage complete repipes, luxury fixture rough-ins, and gas lines; our C-20 team designs and installs HVAC for large, multi-zone estates where comfort has to be invisible.
Estate properties also come with estate infrastructure — long sewer laterals, guest houses, and pool houses that need the same attention as the main residence. Our 911 Drain Lines division provides discreet camera inspections, hydro jetting, and trenchless sewer rehabilitation backed by a 20-year warranty. We build guest houses and ADUs, execute structural improvements under our A General Engineering license, and serve the city’s commercial corridors with high-end tenant improvement work.

Why Beverly Hills Property Owners Choose Mars
Most construction projects fall apart in the gaps between trades. The general contractor blames the plumber, the plumber blames the HVAC tech, and the homeowner is left playing referee. Mars Construction Industries Corp was built to eliminate that problem. We have been a licensed general contractor in Southern California backed by 30+ years of hands-on experience, and we hold four CSLB licenses in-house: A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC — CSLB #1138550.
That means one accountable team from the first walkthrough to the final punch list. When your project needs a repipe, a new sewer lateral, and an HVAC changeout in the same week, you make one call and we sequence all of it. No finger-pointing, no scheduling gaps, no “that’s not my trade.”
We are licensed, bonded, and insured, and we carry SB-PW and SB(Micro) small business certifications. Our family of brands — 911 Drain Lines for drain and sewer work, ADU Cities for accessory dwelling units, Get Your Roof Certified, and Universal Inspect for property inspections — means the same company you trust with your remodel can also camera your sewer line, build your ADU, or inspect a property before you buy it.

Which trades do you handle in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC — all under our own CSLB licenses, so one team is accountable for the whole job.

For drain and plumbing emergencies, our 911 Drain Lines team is available 24/7 at 714.746.7611 — camera inspections, hydro jetting, and sewer repairs, day or night.
Can you build an ADU on my property?
In many cases, yes. Through our sister brand ADU Cities, we have built more than 100 ADUs in the last four years, so we know how to evaluate a lot, design to the space, and build it right.
Do you take on commercial work?
Yes. We handle commercial and tenant improvement projects — office and retail buildouts, restaurant plumbing, and multi-trade renovations — with the same single-point accountability we bring to residential work.
