Laguna Beach is unlike anywhere else in Orange County — an artist colony turned coastal jewel, where cottages cling to hillsides, streets wind instead of grid, and every property has a personality. Building here is bespoke by necessity: hillside lots, coastal moisture, mature landscaping, and design review that protects the city’s character.
Hillside coastal construction is precisely where engineering depth matters most. Additions on sloped lots, drainage that protects foundations, and cottages whose charming old bones hide century-old plumbing — these projects need a contractor with an A General Engineering license, not just a remodeling portfolio. Combined with our B, C-36, and C-20 licenses, Laguna Beach gets one team that can handle the hill, the house, and the systems inside it.
Construction & Remodeling Services in Laguna Beach, CA
We remodel Laguna’s cottages and estates with respect for their character and clear eyes about their age: kitchens and baths rebuilt with coastal-appropriate materials, proper waterproofing, and ventilation that stands up to marine moisture. Behind the charm, our C-36 plumbers renew failing supply lines and our 911 Drain Lines crews camera older sewer laterals — then rehabilitate them trenchlessly with a 20-year warranty, because trenching through a hillside garden is nobody’s first choice.
On the structural side, our A-license team handles hillside additions, drainage improvements that move water away from foundations, and the site work that keeps coastal properties sound. Our C-20 techs replace salt-worn HVAC with equipment specified for the coast. Detached ADUs and guest cottages make the most of Laguna lots, and we coordinate every project with the care a one-of-a-kind property demands.

Why Laguna Beach 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.

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.
