Santa Clarita is one of Los Angeles County’s largest cities — a master-planned valley community of newer subdivisions, HOA neighborhoods, and growing commercial corridors. The housing here is predominantly newer than in the coastal and central parts of the county, which shapes the work: less emergency infrastructure repair, more planned improvement. Homeowners remodel kitchens and baths to personalize production homes, add bedrooms and ADUs as families grow, and replace HVAC systems worn down by valley heat. Businesses need tenant improvements in retail centers, offices, and restaurants. It’s a market where a multi-trade contractor earns its keep on planned projects — additions that need HVAC resized, remodels that need gas lines moved, ADUs that need full utility coordination.
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 for planned projects, that coordination is where the value shows.
Construction & Remodeling Services in Santa Clarita, CA
Kitchen and bathroom remodels are our bread and butter in Santa Clarita’s subdivisions. Production homes have good bones but generic finishes, and homeowners personalize them with full kitchen renovations — new layouts, gas ranges, reconfigured plumbing — and bathroom remodels with modern fixtures and tile. Because our C-36 plumbing license is in-house, fixture relocations and supply-line upgrades are part of the same job, not a separate contractor’s schedule to coordinate.
Additions and ADUs are equally common as families grow. We build room additions — bedrooms, expanded living areas, primary suites — and ADUs through our sister brand ADU Cities, which has built more than 100 ADUs in four years. When an addition changes a home’s heating and cooling load, our C-20 HVAC license means we resize or extend the system as part of the same project instead of leaving comfort as an afterthought.
Valley heat makes HVAC a core service here. We install, replace, and repair air conditioning and heating systems, including full system replacements for aging equipment. Our drain and sewer services — camera inspection, hydro jetting, trenchless repair with a 20-year warranty on sewer lining — cover the infrastructure side. And for the business community, we handle commercial tenant improvement: office build-outs, retail spaces, and restaurant TI in the city’s commercial corridors.

Why Santa Clarita Property Owners Choose Mars
One accountable team — that’s the model. Four licenses in-house (A, B, C-36, C-20) means the addition’s framing, plumbing, and HVAC are all done by us under one contract, sequenced properly instead of stacked across subcontractors. We’ve been operating with 30+ years of hands-on experience, we’re licensed, bonded, and insured (CSLB #1138550), and we’re SB-PW and SB(Micro) certified. For planned projects like remodels, additions, and ADUs, that single point of responsibility is the difference between a smooth project and a coordination headache. Our sister brands — 911 Drain Lines, ADU Cities, Get Your Roof Certified, and Universal Inspect — extend what one call covers.

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.
How does your estimate process work?
We visit the property, walk through the project with you, and provide a written estimate. For additions and ADUs, we scope the full job — construction, plumbing, HVAC — at once so the number reflects the complete project.
