Beaverton Building Permits — Process, Costs & Requirements (2026)

Do I Need a Building Permit in Beaverton, Oregon?

Yes — most construction, remodeling, and structural projects in Beaverton, Oregon require a building permit before work begins. Permits are issued by the Beaverton Community Development Department, located at 12725 SW Millikan Way, Beaverton, OR 97005 (The Beaverton Building). However, there is a critical distinction that catches many homeowners off guard: not every address with a Beaverton mailing address actually falls within Beaverton city limits. Large portions of the area are in unincorporated Washington County, which has its own Development Services department and a completely separate permit process. Before you apply for any permit, you must first confirm whether your property is under City of Beaverton or Washington County jurisdiction — applying to the wrong authority wastes weeks and filing fees.

At Boss PDX, we are a licensed Oregon general contractor (CCB #232383) that handles the full permit process for Beaverton-area projects. From jurisdiction verification through final inspection sign-off, we manage every step so you can focus on the end result rather than the paperwork.

How Do I Know If My Property Is in City of Beaverton or Washington County?

This is the single most important question to answer before pursuing a building permit in the Beaverton area. Your mailing address may say "Beaverton, OR," but that does not guarantee you are within city limits. Neighborhoods along the city's southern and western edges — including parts of the Sexton Mountain area, portions near Scholls Ferry Road, and stretches south of Barrows Road — frequently fall in unincorporated Washington County rather than the City of Beaverton.

There are several ways to verify your jurisdiction:

• Washington County GIS Map: The county's interactive mapping tool lets you enter your address and see exactly which jurisdiction governs your parcel, including any overlapping service districts.
• Call the City of Beaverton: The Community Development Department at (503) 526-2222 can confirm whether your address is within city limits.
• Contact Washington County Development Services: If your property is in unincorporated territory, Washington County's Land Use and Transportation department at (503) 846-8761 handles permits.
• Check your property tax statement: It will list the taxing jurisdictions, which reveals whether you pay city taxes to Beaverton.

The difference matters enormously. City of Beaverton applies its own development code, design review standards, and fee schedule. Washington County uses the Community Development Code (CDC) with different setback requirements, review timelines, and approval thresholds. A project that qualifies for a simple over-the-counter permit in the city might require a full land use review in the county, or vice versa. Boss PDX verifies jurisdiction as our first step on every Beaverton-area project — it shapes the entire permit strategy.

What Types of Projects Require a Building Permit in Beaverton?

The City of Beaverton requires permits for a wide range of residential and commercial work. The general rule is that any project involving structural changes, electrical work, plumbing modifications, or mechanical system alterations needs a permit. Here is a breakdown of common project types:

Residential Projects Requiring Permits

• Home additions and extensions — room additions, bump-outs, second-story additions
• Detached and attached garages — new construction or conversion to living space
• Basement finishing and remodeling — egress windows, bathroom additions, structural modifications
• Kitchen and bathroom remodels — when involving plumbing relocation, electrical panel upgrades, or wall removal
• Accessory Dwelling Units (ADUs) — both attached and detached, per Oregon's state mandate
• Decks and covered patios — structures over 30 inches above grade or attached to the dwelling
• Fences over 6 feet tall and retaining walls over 4 feet
• Roofing — full re-roofs and structural roof modifications
• Water heater and furnace replacements — mechanical permits required
• Electrical panel upgrades — especially common with EV charger installations

Commercial Projects Requiring Permits

Beaverton is home to major employers including Nike's World Headquarters and significant Intel operations nearby. This drives a steady volume of commercial tenant improvement and renovation work that requires permits:

• Tenant improvements (TIs) — office buildouts, retail space reconfigurations
• Change of occupancy — converting retail to restaurant, office to medical, and similar use changes
• ADA compliance upgrades — restroom renovations, ramp installations, accessible entries
• Seismic retrofits — increasingly common for older commercial buildings along Canyon Road and Allen Boulevard corridors
• Mechanical system replacements — commercial HVAC installations

Projects That Typically Do Not Require a Permit

• Interior painting and cosmetic flooring replacement
• Cabinets and countertop replacement (no plumbing or electrical changes)
• Storage sheds under 200 square feet (must still comply with setbacks)
• Minor landscaping and garden fencing under 6 feet
• Like-for-like fixture replacements (same location, no new wiring or piping)

When in doubt, call the Community Development Department or contact Boss PDX — we can tell you quickly whether your project needs a permit and which jurisdiction handles it.

What Are Beaverton's Special Design Review and Overlay Requirements?

Beaverton has several overlay zones and special districts that add layers of review beyond a standard building permit. If your property falls in one of these areas, your project may require design review approval before a building permit can even be issued.

Beaverton Regional Center

The area roughly bounded by Canyon Road, Hall Boulevard, and the MAX Blue Line corridor is designated as the Beaverton Regional Center. Projects here are subject to additional urban design standards focused on pedestrian orientation, building massing, ground-floor activation, and streetscape integration. New construction and major renovations may require Design Review Board hearings, which add 4 to 8 weeks to the approval timeline. The city is actively encouraging mixed-use density in this zone, so adaptive reuse projects — converting older single-use commercial buildings to mixed residential and retail — can sometimes qualify for streamlined review.

Transit-Oriented Development Near MAX Stations

Properties within a quarter-mile of MAX Blue Line stations (Beaverton Central, Beaverton Creek, Millikan Way, and Sunset Transit Center) fall under transit-oriented development (TOD) standards. These standards typically allow higher density and reduced parking requirements, but impose stricter building design criteria around pedestrian connectivity, facade treatment, and ground-floor uses. If you are building or renovating near a MAX station, these TOD requirements shape everything from site layout to the materials you use on the street-facing facade.

South Cooper Mountain Area

South Cooper Mountain is one of Beaverton's newest development areas, annexed over the past decade with purpose-built community planning standards. Projects in this area must comply with specific design guidelines covering lot coverage, stormwater management, trail connectivity, and neighborhood character. The South Cooper Mountain Community Plan sets parameters that differ from standard Beaverton residential zones — most notably around open space preservation, tree canopy retention, and the integration of the regional trail system. New construction and significant additions require demonstrating compliance with these area-specific standards.

Historic and Sensitive Area Overlays

While Beaverton does not have a large historic district like Portland, certain areas — particularly along the original downtown corridor near Farmington Road and Watson Avenue — carry additional review sensitivity. Properties near significant natural resources, wetlands, or identified wildlife corridors may trigger Clean Water Services (CWS) review requirements and additional stormwater management conditions that must be addressed before a building permit is issued.

How Much Do Building Permits Cost in Beaverton?

Beaverton's permit fees are based on the project valuation — the estimated cost of the construction work — plus additional fees for plan review, system development charges (SDCs), and any required land use reviews. Here is a general overview of what to expect:

Project Type	Typical Permit Fee Range	Notes
Bathroom remodel	$300 – $800	Mechanical and plumbing permits often separate
Basement finish	$800 – $2,500	Depends on scope — egress windows add cost
Detached garage	$1,000 – $3,000	Size and electrical service determine fee
Home addition	$2,000 – $6,000+	SDCs may apply for added square footage
ADU (new detached)	$4,000 – $12,000+	SDCs are the largest cost component
Commercial tenant improvement	$1,500 – $10,000+	Varies widely by valuation and occupancy type

In addition to the base permit fee, plan review typically adds 65% of the permit fee, and state surcharges add a small percentage on top. System Development Charges are the largest variable — a new ADU or addition that adds living space may trigger SDCs for parks, transportation, water, sewer, and stormwater that collectively run into the thousands. Beaverton's SDC rates differ from Portland's and from Washington County's, which is yet another reason the jurisdiction question matters.

What Is the Building Permit Process in Beaverton Step by Step?

The City of Beaverton has invested in streamlining its permit process, but the steps and timeline depend heavily on project complexity and whether land use review is involved. Here is the standard sequence:

• Step 1 — Jurisdiction verification. Confirm your property is in City of Beaverton, not unincorporated Washington County.
• Step 2 — Pre-application conference (if needed). For projects that involve land use review, design review, or development in overlay zones, the city offers pre-application conferences to identify requirements before you invest in full plans.
• Step 3 — Plan preparation. Prepare construction documents that meet Oregon Residential Specialty Code (ORSC) or Oregon Structural Specialty Code (OSSC) requirements, along with any applicable Beaverton design standards.
• Step 4 — Permit application submission. Applications can be submitted through Beaverton's online permit portal or in person at The Beaverton Building. Include all required documents — site plans, floor plans, structural calculations, energy compliance forms, and any applicable stormwater or clean water documentation.
• Step 5 — Plan review. The city reviews plans for building code compliance, zoning conformance, and any overlay or design standards. Simple residential projects may take 2 to 4 weeks. Projects requiring design review or land use approval can take 8 to 16 weeks.
• Step 6 — Corrections and resubmittal. If the reviewer identifies issues, you receive a correction letter. Address all items and resubmit — each round of corrections adds 1 to 3 weeks.
• Step 7 — Permit issuance. Once plans are approved and fees are paid, the permit is issued and work can begin.
• Step 8 — Inspections. Schedule inspections at each required stage — footing, foundation, framing, insulation, electrical rough-in, plumbing rough-in, mechanical, and final. Beaverton typically provides next-day inspection scheduling for most inspection types.
• Step 9 — Final inspection and certificate of occupancy. Once all inspections pass, the city issues final approval. Commercial projects and new dwellings (including ADUs) receive a Certificate of Occupancy.

Boss PDX manages this entire sequence for our clients. We prepare permit-ready plans, submit applications, respond to reviewer comments, schedule inspections, and ensure final sign-off. For a broader view of how permits work across the metro area, see our Portland building permits guide.

What Are Beaverton's ADU Rules and Permit Requirements?

Beaverton adopted Accessory Dwelling Unit regulations in compliance with Oregon's statewide ADU mandate (ORS 197.312), which requires cities to allow at least one ADU on any lot zoned for single-family residential use. Beaverton's specific implementation includes the following key provisions:

• One ADU per lot is permitted on residentially zoned properties — either attached (within or added to the primary dwelling) or detached (a separate structure).
• Maximum size is generally 800 square feet or 75% of the primary dwelling's living area, whichever is less. Detached ADUs also face lot coverage and setback constraints specific to the zone.
• No additional parking required. Per state law, Beaverton cannot mandate off-street parking for ADUs.
• Owner occupancy is not required. Oregon law prohibits cities from requiring that the property owner live in either unit.
• Design standards apply in certain overlay zones — particularly near the Regional Center and in South Cooper Mountain — covering exterior materials, roof pitch, and building height.
• System Development Charges are the most significant cost beyond construction — they vary by ADU size and type and can run from $8,000 to over $15,000 depending on current rate schedules.

ADUs are one of the most popular permit-driven projects in Beaverton right now, driven by rising housing costs and the flexibility to create rental income or multi-generational living arrangements. Boss PDX has built both attached and detached ADUs across the Portland metro — reach out for a free estimate on your ADU project.

How Long Does It Take to Get a Building Permit in Beaverton?

Permit timelines in Beaverton vary significantly based on the type and complexity of the project:

• Simple mechanical, electrical, or plumbing permits: Often issued over the counter or within 1 to 3 business days through the online portal.
• Residential remodels and basement finishes: Plan review typically takes 2 to 4 weeks for straightforward projects with complete submittals.
• Home additions and new garages: Allow 3 to 6 weeks for plan review, depending on structural complexity and whether any setback variances or land use reviews are triggered.
• New ADU construction: 4 to 8 weeks for plan review, potentially longer if the property is in an overlay zone requiring design review.
• Commercial tenant improvements: 3 to 8 weeks depending on occupancy classification, fire and life safety requirements, and ADA compliance scope.
• Projects requiring Design Review Board approval: Add 4 to 8 weeks for the land use review process before the building permit application can even be submitted.

The single biggest factor in timeline is completeness of the initial submittal. Incomplete applications or plans that lack required details (structural calculations, energy code compliance, stormwater documentation) trigger correction rounds that each add weeks. Boss PDX submits permit-ready packages that minimize corrections and keep your project on schedule.

How Does Beaverton's Permit Process Differ from Portland's?

Contractors and homeowners who have dealt with Portland's Bureau of Development Services (BDS) often find Beaverton's process noticeably different in several ways:

• Smaller volume, faster review. Beaverton processes far fewer permits than Portland, which generally means shorter review queues and more responsive communication with plan reviewers.
• Different fee structures. Beaverton's fees and SDCs follow their own schedules — they are not derived from Portland's rates. In some cases Beaverton fees are lower; in others (particularly SDCs for new construction), they can be comparable or higher.
• Design review is more common. Beaverton applies design review standards more broadly than Portland does for standard residential work, particularly in the Regional Center and transit-adjacent areas.
• The jurisdiction split. Portland has a clear city boundary for most residential areas. Beaverton's boundary is irregular, and the Washington County overlap creates a unique two-authority dynamic that Portland homeowners never encounter.
• Clean Water Services involvement. Properties in the Beaverton area may need CWS approval for projects affecting impervious surfaces or near sensitive areas — a requirement handled differently than Portland's stormwater review.

Boss PDX works across both jurisdictions regularly. Whether your project is in Portland, Beaverton, or Washington County, we know the specific requirements and reviewers at each agency.

Frequently Asked Questions

Can I pull my own building permit in Beaverton as a homeowner?

Yes, Oregon law allows homeowners to pull their own permits for work on their primary residence. You can apply through Beaverton's online permit portal or in person at The Beaverton Building. However, you are responsible for ensuring plans meet code, scheduling inspections at the right stages, and correcting any deficiencies. Many homeowners pull permits for simple projects like water heater replacements but hire a licensed contractor like Boss PDX for complex work involving structural, electrical, or plumbing components.

What happens if I do work without a permit in Beaverton?

Unpermitted work can result in stop-work orders, fines, and requirements to expose and inspect completed work. The City of Beaverton actively enforces permit requirements, and unpermitted work creates serious problems when you try to sell your home — title companies and buyers' inspectors flag additions, finished basements, and converted garages that lack permit records. Retroactive permits are possible but typically cost more and require opening up walls or ceilings to verify code compliance. It is always cheaper and faster to permit work correctly from the start.

How do I schedule inspections for my Beaverton building permit?

Inspections are scheduled through the City of Beaverton's online portal or by calling (503) 526-2222. Most inspection types can be scheduled for next-day service if you call before the daily cutoff. You will need your permit number and the specific inspection type (footing, framing, electrical rough-in, etc.). The inspector will either approve the work or issue a correction notice listing items that must be addressed before re-inspection. Boss PDX coordinates all inspections for our clients and ensures work is ready before the inspector arrives.

Do I need a permit to finish my basement in Beaverton?

Yes, finishing a basement requires building, electrical, plumbing, and mechanical permits in Beaverton. Basement finishing projects involve framing, insulation, electrical wiring, and often plumbing for added bathrooms — all of which require code compliance and inspections. Egress window requirements are especially important: every basement bedroom must have a code-compliant egress window or door for emergency escape. Boss PDX specializes in basement finishing projects and handles the full permit and construction process.

Are there different permit requirements for Washington County vs. City of Beaverton?

Yes, Washington County and City of Beaverton have different codes, fee schedules, and review processes. Washington County's Development Services department applies the county's Community Development Code, which has different setback, lot coverage, and land use provisions than Beaverton's development code. The application forms, plan review timelines, and inspection procedures also differ. If your property has a Beaverton mailing address but is in unincorporated Washington County, you must apply through the county — not the city. Boss PDX knows both systems and handles projects in either jurisdiction.

What permits do I need to build an ADU in Beaverton?

A new ADU in Beaverton requires building, electrical, plumbing, and mechanical permits, plus potentially a land use review. The building permit process requires full construction plans, structural engineering for the foundation and framing, energy code compliance documentation, and site plans showing setbacks and lot coverage. If your property is in an overlay zone such as the Regional Center or South Cooper Mountain, design review may also be required. System Development Charges represent the largest non-construction cost and are assessed at permit issuance. Boss PDX manages the complete ADU process from design through occupancy.

How much does a building permit cost for a home addition in Beaverton?

Building permit fees for a home addition in Beaverton typically range from $2,000 to $6,000 or more, depending on the project valuation. The base permit fee is calculated from a valuation table, with plan review adding approximately 65% of the base fee. If the addition increases living space, System Development Charges for transportation, parks, water, sewer, and stormwater may apply — these can add several thousand dollars. Mechanical, electrical, and plumbing permits are filed and paid separately. For a precise estimate, request a free project estimate from Boss PDX, and we will calculate the full permit cost as part of your project budget.

Does Beaverton require special permits for work near MAX light rail stations?

Properties near MAX Blue Line stations are subject to transit-oriented development standards that may add design review requirements. Within a quarter-mile of stations like Beaverton Central, Beaverton Creek, and Millikan Way, the city applies specific standards for building design, pedestrian access, and parking. These standards do not create a separate "transit permit," but they can trigger design review board hearings that must be resolved before a standard building permit is issued. Projects that comply with the transit-area standards may actually benefit from relaxed parking requirements and increased allowable density.

Can Boss PDX handle the entire permit process for my Beaverton project?

Yes — Boss PDX manages the complete permit process from jurisdiction verification through final inspection. As a licensed Oregon general contractor (CCB #232383), we prepare permit-ready construction documents, submit applications, respond to plan review comments, schedule and pass inspections, and secure final sign-off. We work in the City of Beaverton, unincorporated Washington County, Portland, and communities across the metro area.
