Meet INVICTA · Design-build

One team. From first sketch to final inspection.

Most homeowners juggle a designer, an engineer, a permit runner and a contractor — and pay for every miscommunication between them. INVICTA brings it all under one contract. We plan the space, draw it, walk it through the city and build it, with one point of contact the whole way.

We build for the way families live now: rental income units, room for aging parents, a primary suite you actually want to wake up in. Every project is built with modern systems — efficient all-electric options, solar-ready roofs and smart-home wiring as standard thinking, not upgrades.

FAQ

Questions homeowners and owners ask us.

Don’t see yours? Ask it in your feasibility request and we’ll answer it in your report.

Is the feasibility report really free?

Yes. There’s no cost and no obligation. It’s how we help you decide whether a project makes sense before you invest in plans.

What does the report include?

A review of your lot’s zoning and setbacks, the build options that fit, a utility routing plan, a realistic budget range and an estimated timeline from design to move-in.

Can I build an ADU on my property?

Most single-family lots in California can add at least one ADU, and many multifamily lots can add several. Size, placement and type depend on your lot and city — that’s exactly what the feasibility report answers.

Garage conversion or detached ADU — which is better?

A garage conversion usually costs less and moves faster because the structure already exists. A detached ADU gives you more size, privacy and layout freedom. Your report compares both for your lot.

Do you handle design and permits?

Yes. INVICTA is a design-build company: design, renderings, engineering coordination, permit drawings, plan check and construction are all handled under one contract.

What is INVICTA Studio?

INVICTA Studio is our free online design tool. ADU Studio lets you see your property on a satellite photo, measure your yard or garage and lay out an ADU room by room. Kitchen Studio lets you try cabinets, countertops and floors on a photo of your kitchen.

Do you do commercial work?

Yes. We build restaurant and retail tenant improvements, grease interceptors, office and medical suites, ADA upgrades and change-of-use projects across LA County and Orange County.

Where do you work?

We serve LA and OC County — all of Los Angeles County and Orange County.

Your lot has more potential than you think.
