West Hollywood is dense, urban, and always in motion — a compact city of condos, apartment buildings, and commercial corridors built around nightlife, retail, and dining. The construction work here reflects that density: condo and apartment remodels in buildings with HOA rules and tight access, older apartment buildings needing repipes and system upgrades, and a constant churn of restaurant, retail, and office tenant improvements along the commercial strips. Projects here come with logistical layers — parking constraints, limited staging, building management coordination — and they cross trade lines constantly. A restaurant TI needs plumbing and HVAC; a condo bath remodel needs drain work; an apartment building needs water heaters and gas lines. One multi-trade contractor keeps it all under one roof.
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). One accountable team handles your construction, plumbing, drain and sewer work, and HVAC under a single contract — and we’re experienced with the HOA, building-management, and tight-access conditions West Hollywood projects demand.
Construction & Remodeling Services in West Hollywood, CA
Condo and apartment remodels are a core part of our West Hollywood work. We remodel kitchens and bathrooms in condos, townhomes, and apartments — coordinating with HOAs and building management on approvals, insurance, work hours, and common-area protection — with our C-36 plumbing license in-house so fixture relocations and supply-line upgrades stay inside one job. Small urban bathrooms and kitchens demand smart layouts, and we plan the plumbing and construction together from the start.
Older apartment and condo buildings need infrastructure work: repipes, water heater replacements, and gas line work, all in-house trades for us. Our drain and sewer services — camera inspection, hydro jetting, trenchless repair — come with a 20-year warranty on sewer lining, valuable in a dense city where excavation disrupts residents and businesses alike. We also install, replace, and repair HVAC systems for residential units and commercial spaces.
The commercial side is where West Hollywood never sleeps: tenant improvement for restaurants, retail, nightlife venues, and offices. Because we hold plumbing and HVAC licenses in-house, a restaurant build-out that needs grease-adjacent plumbing, restroom work, and ventilation and HVAC stays under one contract with one team accountable for the schedule — critical when every week of delay is lost revenue.

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. Verify any license on the CSLB website before hiring. Ours is CSLB #1138550 — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC.
Can you work within my HOA’s or building’s rules?
Yes. We’re experienced with condo and apartment remodels: HOA approvals, insurance certificates, restricted work hours, elevator scheduling, and common-area protection. Share the requirements up front and we’ll plan around them.
How does your estimate process work?
We visit the property, walk through the project with you, and provide a written estimate. For commercial TI, we scope the full job — construction, plumbing, HVAC — at once so the schedule and number reflect the complete project.
Which trades do you handle in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC, all under our own 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.
