Ask how long it takes to build a custom home and you'll probably hear, "From the time we break ground..."

But by the time excavation begins, months may already have gone into site research, design, engineering, pricing, permits, and materials.

We've helped dozen of homeowners set realistic schedules to build their dream custom homes in Oregon. Here's the bottom line: for a true custom home in Oregon, a realistic plan usually allows about 18 to 30 months from early planning through move-in.

This article shows you where that time goes, and how building in Portland or Bend can change the path.

How long does it take to build a custom home in Oregon?

A fully custom home in Oregon often takes about 18 to 30 months from initial planning through move-in.

Construction after permits are issued may take roughly 12 to 18 months or longer, depending on the home, site, and finish level.

That overall range assumes you have a reasonably feasible property or are evaluating one as the process begins. An open-ended land search can add months or years. Design, procurement, and permit work may also overlap, so the phase ranges below shouldn’t simply be added together.

If you’re planning the budget alongside the schedule, see our Oregon custom home cost guide.

The custom home timeline, start to finish

1. Site feasibility and team assembly: about 1–2 months

Before you design around a property, confirm that the property can support the home you want. Early feasibility work may address zoning, utilities, access, topography, soils, trees, drainage, and other constraints that affect the design, budget, or schedule.

This is also the time to establish your goals and target budget and begin assembling the architect, builder, engineers, and other key consultants. Bringing a builder in before you buy the property can help uncover costly obstacles while you still have options.

If you’re weighing a new build against changing an existing home, our custom home, remodel, or addition guide can help clarify the right path.

2. Design, engineering, and preconstruction: about 4–8 months

During this phase, the home moves from ideas to coordinated construction documents. The work may include architectural design, structural and civil engineering, energy requirements, constructibility reviews, and the details needed for pricing and permits.

The strongest schedules are built here. Budget updates should keep pace with the drawings. Major selections need clear deadlines. Windows, cabinetry, appliances, specialty fixtures, and other long-lead items should be identified before they become urgent.

Brothers’ preconstruction and scheduling process is designed to establish clear scope, plan trade coordination, and show how meaningful changes affect both budget and timing.

3. Permits and other approvals: plan for about 2–6+ months

The permitting allowance may include application preparation, intake, building and zoning review, site or tree review, utility coordination, corrections, and resubmittals. A teardown, private-community design review, or unusual land-use issue can add another approval track.

This isn’t a guaranteed city review time. The project’s jurisdiction and complexity matter, as does the completeness of the plans. Portland publishes a permit review dashboard with current data for residential permits. Check current local information when the project is ready to submit rather than relying on an old rule of thumb.

4. Construction: about 12–18+ months

Once permits are in hand, construction typically moves through site preparation and foundation; framing and dry-in; plumbing, electrical, and HVAC; insulation and drywall; exterior and interior finishes; and final site work.

Custom homes take longer than standardized production homes because the details, materials, and site conditions are specific to the project. Large openings, complex rooflines, specialty finishes, difficult access, weather, inspections, and trade coordination can all influence the critical path. A useful construction schedule accounts for those dependencies instead of treating each trade as an isolated task.

5. Final inspections, punch list, and move-in: about 2–6 weeks

A home that looks nearly finished may still need final inspections, system testing, occupancy approval, walkthroughs, punch-list work, and owner orientation. Treating closeout as a real phase gives the team time to finish details properly and gives the homeowner a more dependable move-in plan.

How Portland and Bend can affect the schedule

Building a custom home in Portland

Portland custom homes are often infill projects. If an existing house must be removed, that work and its approvals need to be planned before the new home can begin. Portland requires qualifying houses and duplexes built in 1940 or earlier, along with certain historic resources, to be deconstructed rather than mechanically demolished. The city explains the steps in its deconstruction requirements.

Urban access, trees, grading, erosion control, utilities, and site-specific zoning can also affect the review path. None of these automatically makes Portland slow, but they need to be identified early enough to appear in the real schedule.

Building a custom home in Bend and Central Oregon

First, determine whether the property is inside Bend or in unincorporated Deschutes County. The responsible agencies and requirements differ.

For new residential permit applications submitted within Bend on or after May 15, 2026, the city’s adopted R327 standards add wildfire-hardening requirements for elements such as roofing, gutters, windows, vents, and siding. Those requirements should be addressed during design and selections, not discovered at permit submission.

For projects in unincorporated Deschutes County, the county’s residential research checklist directs applicants to resolve applicable land-use, septic, and driveway-access requirements before applying for the building permit. A private community may have its own architectural review as well.

Neither Portland nor Bend is automatically faster. The property, jurisdiction, design, and approval path usually matter more than the city name.

What most often extends a custom home timeline?

Some delays can’t be eliminated. Many can be reduced with earlier investigation and firmer decisions. Common schedule pressures include:

• Site or utility problems discovered after design is underway
• Incomplete or poorly coordinated drawings
• Permit corrections or additional approval requirements
• Major design changes after pricing or construction begins
• Late selections and long-lead materials
• Weather or difficult site access
• Missed inspections and gaps in trade coordination

The goal is to expose risk while there’s still room to respond. A late decision can affect far more than one finish or fixture; it can shift purchasing, inspections, and several trades that follow.

How to keep your custom home on schedule

• Involve the builder during site feasibility or early design.
• Align the design with a realistic target budget before the plans become difficult to change.
• Investigate the site and approval path before finalizing the scope.
• Set decision deadlines and identify long-lead materials early.
• Use a baseline schedule, short-term look-ahead planning, and regular updates.
• Review the cost and schedule effect of every meaningful change before approving it.

Good planning won’t prevent every surprise. It gives the team more time to solve problems without letting one issue ripple through the entire project.

When should you contact a custom home builder?

Ideally, contact a builder before purchasing the property or before the design is substantially complete. Early builder input can test the site and design against the budget, identify construction challenges, and create a more realistic schedule.

Already own land or have drawings? You haven’t missed the window. A builder can assess what’s resolved, what remains open, and what could affect the target move-in date. Our guide to choosing a custom home builder in Oregon offers practical questions to ask before hiring.

Custom home timeline FAQ

Does the 18–30 month custom home timeline include design and permits?

Yes. The overall planning range covers site feasibility, design and engineering, permits, preconstruction, construction, closeout, and move-in. An open-ended property search isn’t included.

How long does it take to build after the permit is issued?

Construction for a fully custom home often takes about 12 to 18 months or longer. Home size, architectural complexity, site conditions, finish level, long-lead materials, inspections, and weather can all change that range.

Is it faster to build a custom home in Portland or Bend?

Neither market is inherently faster. Portland projects may involve infill constraints, deconstruction, and urban site reviews. Bend-area projects may involve wildfire-hardening requirements, rural infrastructure, county approvals, or private-community review.

Can a custom home be completed in one year?

A relatively straightforward home may be built within a year after permits are issued, but that isn’t a reliable expectation for the full custom-home process. Design, engineering, permitting, construction, and closeout will usually take longer in total.
