Custom home building · Tigard, OR
Your House, Your Rules.
Choosing a custom home builder in Tigard means choosing who's accountable for one of the biggest decisions you'll make — and it shouldn't be a guessing game. De Marco Builders has spent nearly 30 years turning that decision into finished homes across the Portland metro, with a price and a timeline that hold from day one to move-in.
Custom Built for Tigard
Yours From the Ground Up
A custom home isn't supposed to look like the house next door — it's supposed to solve for how your household actually operates day to day. Maybe that means a layout that keeps work and rest separate, extra storage where you actually need it, or a kitchen built around how you really cook, not how a showroom says you should. In Tigard, where lots and neighborhoods vary block to block, that kind of intentional design matters even more.
We build that intention into the process itself. Rather than passing your project between separate design and construction firms, one De Marco team carries it the whole way — which means the home you signed off on in the design phase is the home you actually get.

Craft, not chance
The Difference Is in the Details.
Framing, mechanical systems, structural sequencing — none of it is visible in the finished photos, but all of it determines whether a custom home holds up. Cut corners here and the consequences don't show up right away; they show up years later, in ways that are expensive to fix.
That's why De Marco Builders keeps every phase of construction under direct, hands-on management, instead of splitting the work across separate subcontractors with no one tying it all together. We've applied that discipline across more than 1,400 projects throughout the Portland metro, and it's what makes a fixed price and a guaranteed schedule possible for a custom home in Tigard — not just a promise, but a track record.
THE PROCESS
What to Expect.
Before anything gets drawn, we sit down and talk through how you want the home to function — what's non-negotiable, what's flexible, and what problems you're trying to solve. That conversation shapes design, engineering, and the permitting process that follows, with you looped in at each stage rather than left waiting for a reveal.
Once permitting clears, construction begins on the date we set — and doesn't drift from it. You'll work with one point of contact for the entire build, get regular updates as work progresses, and land on a completion date that actually holds, backed by our 100% on-time record across 1,400-plus projects in the Portland metro.

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.
