Agoura Hills is foothill living at its best — larger lots, equestrian pockets, and homes that range from classic ranch properties to custom hillside builds. Properties like these don’t fit a one-trade contractor. A regrade, a barn-adjacent guest house, a kitchen remodel that touches gas, water, and HVAC at once: that’s the kind of project where hiring three separate companies turns into a scheduling mess. Mars Construction Industries is a general contractor holding four CSLB licenses in-house, so one accountable team handles the whole scope in Agoura Hills.
Construction & Remodeling Services in Agoura Hills, CA
On larger foothill lots, projects tend to sprawl. A home addition might run new gas lines for a pool heater, extend drain lines across the property, and need a bigger HVAC system to condition the new square footage.
We see a lot of whole-home updates in Agoura Hills — owners of ranch-style homes opening up kitchens, adding primary suites, and modernizing systems that are decades old. Our in-house plumbers handle repipes and gas line work, our HVAC crew sizes and installs new systems, and our builders tie it all together under one schedule.
- Home additions and whole-home remodels — design-to-finish construction managed by one team.
- Kitchen and bathroom remodels with in-house plumbing rough-in and fixture installation.
- Repipes and gas line work for aging ranch homes and hillside properties.
- HVAC replacement and installation sized for larger foothill homes and additions.
- ADUs and guest houses — over 100 built in four years through our ADU Cities brand.
- Drain and sewer services including camera inspection, hydro jetting, and trenchless repair backed by a 20-year lining warranty.
- Commercial and tenant improvement for properties along the Ventura Freeway corridor.
Whether it’s a full custom remodel, an ADU for a multigenerational household, or a tenant improvement on a commercial property along the 101 corridor, you get the same deal: one contractor, four trades in-house, and a written estimate before work starts.
Why Agoura Hills Property Owners Choose Mars
Most remodeling projects fail in the gaps between trades. The plumber roughs in before the framer is done, the HVAC sub never shows, and the homeowner ends up project-managing three companies that blame each other. We built Mars Construction Industries to eliminate that problem. We hold four CSLB classifications in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC — so the crew doing your addition is the same company doing your repipe and your HVAC changeout.
We’ve been at it with 30+ years of hands-on experience, working from our Orange County home base across Southern California. We’re licensed, bonded, and insured (CSLB #1138550), and our SB-PW and SB(Micro) certifications reflect a company built to do right by the communities we serve. When you hire Mars, you get one accountable team, one phone number, and one company standing behind the finished work.
Our sister brands extend that accountability: 911 Drain Lines for drain and sewer emergencies, ADU Cities for accessory dwelling units, Get Your Roof Certified for roof certifications, and Universal Inspect for inspection services. Whatever your property needs, there’s a Mars team for it.

Frequently Asked Questions
We have a hillside lot in Agoura Hills. Can you handle grading and drainage work too?
Our A General Engineering classification covers general engineering work including grading and drainage-related construction, and because the same company also holds the building, plumbing, and HVAC licenses, site work and the structure above it stay coordinated.
Are you a licensed contractor?
Yes. Mars Construction Industries Corp holds CSLB license #1138550 with four classifications: 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 California contractor’s license status at cslb.ca.gov.
How does your estimate process work?
It starts with a conversation and a walkthrough of the project. We look at the full scope, identify what each trade will need to touch, and give you a written estimate with clear, combined pricing. Because our plumbers, HVAC techs, and builders all work for the same company, we price the whole job once instead of stacking separate subcontractor bids with separate markups.
Which trades do you keep in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC are all in-house under our four license classifications. When a project also needs electrical work, we coordinate with licensed electrical subcontractors so the work stays on one schedule under one accountable team.
Do you offer emergency service?
Yes. Our 911 Drain Lines brand runs 24/7 drain and plumbing emergency service at 714.746.7611. For sewer line emergencies, we can camera-inspect the line, clear it, and talk through repair options including trenchless repair and sewer lining backed by a 20-year warranty.
Do you build ADUs?
Yes. Through our sister brand ADU Cities, we’ve built more than 100 accessory dwelling units in the last four years. From detached backyard units to garage conversions, we handle the full build with the same in-house plumbing, HVAC, and general construction crews.
