Manhattan Beach rebuilds itself lot by lot — original beach cottages make way for stunning modern homes, and even the homes that stay get renovated to a standard that matches the neighborhood. With some of the highest property values in the South Bay, every project here is a serious investment, and owners expect the execution to match.
High-value projects are where the multi-trade model pays for itself. A Manhattan Beach rebuild or major renovation runs structural work, full plumbing, and sophisticated HVAC in tight sequence — and any gap between those trades shows up in the schedule and the budget. 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 owns the entire sequence from foundation to finish.
Construction & Remodeling Services in Manhattan Beach, CA
Our Manhattan Beach work spans full custom rebuilds, major additions including second stories, and whole-home renovations of both cottages and newer homes. We handle the structural scope under our A and B classifications, complete plumbing systems with our own C-36 crews — repipes, gas lines for outdoor living, water heater systems — and HVAC designed for the home through our C-20 division, including zoned systems for larger footprints.
For owners keeping their home’s footprint, we do high-finish kitchen and primary suite remodels and the mechanical renewals beach homes need: salt air shortens the life of condensers, water heaters, and exterior plumbing, so we plan equipment placement and protection with the coastal environment in mind. Our 911 Drain Lines division camera-inspects sewer laterals and performs trenchless repair where applicable — our sewer lining carries a 20-year warranty.
ADUs are increasingly popular on Manhattan Beach lots. Through our sister brand ADU Cities, we’ve delivered more than 100 accessory dwelling units in four years — detached units and garage conversions built start to finish by the same team, to the same finish standard as the main house.

Why Manhattan Beach Property Owners Choose Mars
On lots this valuable, the only acceptable surprise is none at all. Here’s the accountability Manhattan Beach 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.
We’re considering a teardown rebuild. Can you handle the whole project?
Yes. We manage rebuilds from the structural scope through complete plumbing and HVAC systems — our A, B, C-36, and C-20 classifications cover the core of the project in-house. For work outside our classifications, such as electrical, we coordinate properly licensed subcontractors and stay accountable for them as your general contractor.
How do you keep a major project on schedule?
Our construction, plumbing, and HVAC crews work for the same company on one master schedule — we’re not waiting on subcontractors juggling other jobs. You’ll have a single project manager and a single phone number from start to finish.
Does salt air affect new construction the same way?
New equipment still lives in salt air, so yes — placement and protection matter from day one. We plan for the coastal environment in every beach-city project, whether it’s a rebuild or a mechanical replacement, so systems last as long as they’re designed to.
