The Process

Four phases. Zero surprises.

We've structured every TI project the same way since day one — because the fastest way to blow an opening date is a phase you didn't plan for. Here's exactly how your project moves from signed contract to grand opening.

01

Scope & Estimate

Site walk, needs assessment, and a line-item bid — not a back-of-napkin number. You see exactly where the money goes before you sign.

Days 1–5
02

Design & Permit

Plans, MEP coordination, and permit submittal through your local AHJ. We speak the language of every OC city planning department.

Weeks 2–6
03

Build

Daily site management, weekly owner reports, transparent change-order process. The jobsite stays clean. The schedule stays honest.

Per scope
04

Inspect & Open

We sweat the final inspection so you don't. Punch list closed, COO secured, you flip the Open sign on the date we promised.

Final week
What We Build

Commercial build-outs, end to end.

Every project starts vacant or stripped to concrete. We turn it into a fully inspected, occupancy-ready commercial space — coordinating trades, timelines, landlords, and city officials so you only have to answer the questions that actually require you.

☕

Café Construction

Espresso bar rough-ins, grease interceptors, Type II hoods, health department walk-throughs, and the bar-top finish your brand deserves — handled start to finish.

🍽️

Restaurant Construction

Full kitchen build-outs, Type I hood systems, FRP, quarry tile, grease lines, and dining-room finishes. Code-compliant, inspector-ready, and delivered on your soft-opening date.

💼

Office Build-Outs

Private offices, open floor plans, conference rooms, glass walls, and IT infrastructure.

🛍️

Retail Spaces

Storefronts, fixtures, finishes, fitting rooms, and brand-aligned design execution.

📐

Design / Build

One team, one contract — from schematic sketch through final certificate of occupancy.

🏗️

Tenant Improvements

Converting raw shells and prior-use spaces into your occupancy-ready footprint. Permits, MEP, finishes, and inspections all managed in one tight schedule.

⚡

Permitting & Inspections

We carry your plans through the city — from plan check corrections to the final sign-off walk. Your opening date doesn't slip because of a paperwork snag.

Why Commercial Owners Choose Kubus

The drawings are where the budget gets won or lost.

Most TI projects go sideways long before a shovel hits dirt. We invest hours with you — and with the architect, the MEP engineer, and the city — so that the numbers on page one match the numbers at final walk. That's how we keep openings on schedule and owners out of surprises.

Built Different

The Kubus Standard.

We're not a volume shop. We take on a deliberate number of projects per quarter so every client gets the project management they're paying for — and so no one learns at month three that their GC is distracted.

On✓

On-Time Delivery

Schedules built backwards from your opening date, with buffer for real-world permit timelines.

100%

Code-Compliant

We don't pass inspection by luck. Plans, rough-ins, and finishes are pre-walked before every call.

1GC

Single Point of Contact

One PM from estimate to handoff. No sub-shuffle, no finger-pointing, no "that's not my scope."

$=

Budget Fidelity

Transparent change-order process. If something moves, you see the number before it moves.

What Owners Say

4.8 stars. 33 reviews. Zero excuses.

Commercial build-outs are stressful. The measure of a good contractor isn't whether problems come up — it's how fast they get solved and whether the owner's opening date still holds. Here's what our clients have said.

★★★★★

"Kubus ran our café build-out from permit to opening. Every inspection passed on the first walk. They gave us the opening date and they hit it — that's all we could ask for."

M
Café Owner
Irvine, CA
★★★★★

"Clean jobsite, consistent communication, and honest numbers. After dealing with two other contractors on prior locations, Kubus is the one we call now."

J
Restaurant Group
Costa Mesa, CA
★★★★★

"Office TI delivered on time, on budget, and with the finish quality we specced. Plan-check corrections handled without us even being looped in. Highly recommended."
