How Long Does It Take to Build a Custom Home in Portland, OR?

Timeline is one of the first things people ask when they start thinking about building a custom home. And it’s a fair question, because the answer affects everything: when you need to give notice on a lease, whether you should sell your current home now or later, and how to plan your finances around a construction loan.
The honest answer is that no two custom home projects take exactly the same amount of time. Your lot, your jurisdiction, your plan complexity, your finishes selections, and your financing situation all play a role. What we can do is walk you through each phase of the process, explain what drives the timeline in each one, and help you go in with realistic expectations.
The Three Phases of a Custom Home Build
Every custom home project moves through three broad phases, each with its own timeline and its own variables. Understanding these phases helps you see not just how long things take, but why.
Phase 1: Pre-Construction
This phase covers everything that happens before a shovel touches the ground: site evaluation, plan design, permitting, finish selections, budget finalization, and loan approval. It is almost always the longest phase, and it is the one buyers most often underestimate.
Plan design alone takes time, especially when a custom plan is needed to fit your specific lot. Permitting adds more. Jurisdictions across the Portland metro area vary considerably in how long permit review takes. Some are relatively quick; others can run several months for a residential new build. We tell our clients to plan for permitting to take time and to not schedule anything around a fixed permit approval date until they have it in hand.
Your financing also happens in this phase. Construction loan approval requires permitted plans, a finalized budget, and a builder contract, so everything in this phase feeds the next one. Rushing through pre-construction to get to the build faster almost always creates problems downstream.
Phase 2: Construction
Once your permit is issued and your loan is approved, construction begins. This is the phase most people picture when they think about building a home: framing, roofing, rough plumbing and electrical, insulation, drywall, finish work, and final systems.
Construction timelines are affected by the size and complexity of the home, weather, subcontractor availability, and how quickly decisions get made when questions come up on the job site. For a typical 3,000 SF two-story home in the Portland area, construction is a multi-month process. We schedule structured walk-throughs at key milestones so you’re never out of the loop: framing, plumbing rough-in, and electrical rough-in each get their own dedicated review before work is covered up.
One thing that reliably extends construction timelines is delayed finish selections. If tile, fixtures, cabinetry, or appliances aren’t selected and ordered well before they’re needed on the job site, the build waits. We work through finish selections with you during pre-construction specifically to avoid this.
Phase 3: Close-Out
The close-out phase covers the final stretch: a new home orientation where we walk you through all systems and features, a final walk-through with a punch list of any remaining items, certificate of occupancy, and key release. This phase is typically the shortest, but it is not a formality. The final inspection and certificate of occupancy are required before you can legally move in, and the municipality controls that timeline.
The Westwood Homes Process, Step by Step
Here is every stage of our process from first conversation to move-in day, and what’s happening at each one:
# | Step | What’s Happening |
1 | Site Evaluation & Feasibility | We assess your lot for buildability, utility access, and site-specific cost factors before anything is signed. |
2 | Agreement & Deposit | The fee-build contract is signed and a deposit is collected. Your costs and our fee are agreed to upfront. |
3 | Design or Select House Plan | We work with you and our plan designer to create a plan that fits your lot, family, and budget. |
4 | Submit Building Permit | Plans are submitted to the jurisdiction. Review times vary significantly across the Portland metro area. |
5 | Design Meeting & Finish Selections | You select interior and exterior finishes. Completing this early prevents delays once construction starts. |
6 | Finalize Budget | With plans complete and selections made, the full budget is locked in before the loan is submitted. |
7 | Loan Approval | Construction loan is approved based on the finalized plans and budget. |
8 | Permit Issued / Construction Begins | Once the permit is in hand and financing is secured, we break ground. |
9 | Framing Walk-Through | You tour the framed structure before walls are closed in. A key milestone for layout confirmation. |
10 | Plumbing Walk-Through | Rough plumbing is reviewed and approved before it’s covered by drywall. |
11 | Electrical Walk-Through | Rough electrical is reviewed and approved before it’s covered by drywall. |
12 | New Home Orientation | We walk you through every system, fixture, and feature of your completed home. |
13 | Final Walk-Through & Key Release | Punch list items are confirmed complete. Certificate of occupancy obtained. Keys handed over. |
14 | Move-In Day | Your home is yours. |
What Has the Biggest Impact on Your Timeline
Of all the variables that affect how long your build takes, three stand out:
• Permitting. This is the variable most outside your control. The City of Portland and surrounding jurisdictions each run their own review processes, and turnaround times fluctuate based on their workload. Some projects move through quickly; others sit in queue. Getting plans submitted accurately and completely the first time reduces the risk of review comments that send things back to the designer.
• Finish selections. Custom cabinets, specialty tile, appliances, and fixtures all have lead times that need to align with when they’re needed on the job site. If selections are delayed, delivery is delayed, and the build waits. We build a selection schedule into the pre-construction phase to get ahead of this.
• Decision speed. Questions come up during construction. When they’re answered quickly, the project keeps moving. When they sit unanswered for days or weeks, the schedule slips. Being an engaged, responsive client is genuinely one of the most effective ways to keep your timeline on track.
