Maywood is one of the smallest and densest cities in Los Angeles County — compact residential lots, small multifamily buildings, and a hardworking community where every square foot of housing matters. Projects here are practical by necessity: adding a bedroom, converting a garage, keeping an aging building’s systems running.
Small, dense, and practical is exactly where a multi-trade contractor helps most. On a tight Maywood lot, you can’t afford three separate crews tripping over each other — and a landlord with a four-unit building can’t afford a plumber who doesn’t coordinate with the remodeler. 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 licensed, bonded, and insured team handles the whole job on one schedule.
Construction & Remodeling Services in Maywood, CA
Our residential work in Maywood focuses on additions, kitchen and bath remodels, and the ADU and garage conversions that make so much sense on small lots. Through our sister brand ADU Cities, we’ve delivered more than 100 accessory dwelling units in four years — giving families room to grow without moving, all handled start to finish by one team with a single written proposal.
For Maywood’s small multifamily buildings, we handle unit renovations and turnovers, building repipes sequenced to keep tenants in place, water heater systems, and common plumbing — our own C-36 crews doing the work on our own schedule. And our 911 Drain Lines division covers the underground: camera inspection, hydro jetting, and trenchless sewer repair with a 20-year warranty on lining.
HVAC rounds out the package — install, replacement, and repair for homes and small apartment buildings through our C-20 division, plus water heaters and gas lines. One call covers all of it: 310.880.9718.

Why Maywood Property Owners Choose Mars
Tight lots, full houses, zero patience for runaround. Here’s the straight-up model Maywood gets:
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.
Our lot is small. Can you still add space?
Often, yes. Garage conversions and ADUs are designed exactly for small lots, and additions can work where setbacks allow. We’ll walk the property, look at what’s actually possible, and give you a straight answer — including telling you when something doesn’t pencil out.
We own a small rental building. Can you handle the plumbing across all units?
Yes. We do building-wide repipes and plumbing upgrades sequenced unit by unit to minimize disruption, plus water heaters and common-area plumbing — all with our own licensed crews.
Can you build an ADU on my property?
Yes. Through our sister brand ADU Cities, we’ve delivered more than 100 accessory dwelling units in the last four years — garage conversions, detached units, and attached additions. We handle the project from design coordination through construction, plumbing, and HVAC, so the ADU is finished by the same accountable team that started it.
