Commercial Construction · Tigard, OR
Commercial Builds, On Time.
As a commercial contractor in Tigard, De Marco Builders brings the same accountability that homeowners across the metro already trust to offices, retail buildouts, and tenant improvements of any size. From first walkthrough to final punch list, one team handles design, permitting, and construction, so nothing falls through the cracks between phases.
A reputation we've earned
It Isn't a Promise, It's a Record.
A lot of contractors promise a deadline. Few actually hit it. De Marco Builders has held a 100% on-time completion record, using critical path scheduling that moves projects along up to 10 times faster than typical industry timelines — a difference that matters most on commercial work, where every week of delay is a week of lost revenue or rent paid on a space that isn't open yet.
That track record isn't a one-off. It's the same standard we've applied to every project since 1996, under the same ownership the entire time — so when we give you a completion date, it's a date we've already proven we can hit.
Local Knowledge, Real Advantage
Washington County's Commercial Side, Covered.
Every commercial project in Tigard moves through its own permitting process, and that process runs on its own timeline — one that's easy to underestimate if you haven't worked through it before. We plan for that from the start, so approvals don't turn into the reason your project falls behind schedule.
Tigard's commercial spaces also come in a lot of forms, and each one comes with different requirements before construction can begin. That's where working with a contractor who's navigated it before pays off. De Marco Builders brings three decades of Portland Metro experience to every commercial project in Tigard, so you're not figuring things out as you go.
THE PROCESS
What to Expect.
Commercial construction moves through several phases — pre-construction planning, permitting, site preparation, and construction — each requiring precise coordination to stay on schedule and on budget. In Tigard, that planning phase matters even more, since building codes and permit requirements need to be worked out thoroughly before anything breaks ground.
Commercial projects often involve active businesses or time-sensitive openings — coordination that goes beyond standard construction practice. Once construction is underway, expect consistent communication, documented change management, and a job site maintained to a professional standard throughout.

How do you price a project?
Every proposal from De Marco Builders provides complete cost transparency. Our estimates clearly show the construction costs, company overhead, profit, and total project cost so clients fully understand where every dollar is allocated.
Do you require a deposit?
No. Never. We do not require an upfront deposit. The first payment is due only after a portion of the contracted work has been completed.
What happens if costs change during the project?
We guarantee the contract price through project completion unless the homeowner requests additional work beyond the original scope or unforeseen structural conditions are discovered that were not visible during the initial evaluation.
Can you work within a specific budget?
Absolutely. De Marco Builders is a budget-driven builder. We work within the client’s established budget throughout the design, engineering, permitting, and construction phases. We utilize value-engineering principles to maximize quality while maintaining budget goals.
Are you licensed, bonded, and insured?
Yes. De Marco Builders is fully licensed, bonded, and insured. We maintain all required certifications and operate in full compliance with state regulations.
How do you handle unexpected issues that come up mid-project?
Unexpected issues are rare because of our extensive experience and thorough planning process. If an unforeseen issue does arise, it is addressed immediately, typically within 24 hours. We resolve issues in a code-compliant manner while protecting the project schedule.
How often will I receive updates?
Communication is one of our highest priorities. Once a client signs a contract, we maintain frequent communication throughout design, engineering, permitting, and construction. Clients receive regular progress updates, photos, and end-of-day reports so they remain informed from start to finish.
