The exact paperwork Oregon agencies require to issue a building permit

Most Oregon building permit applications stall for the same reason: the portal asks for specific documents, and one or two are missing or mislabeled. The state runs on a uniform building code with local administration, so the list is consistent in concept but precise in execution. Below is how Oregon jurisdictions ask for plans and supporting materials, what each document is meant to prove, and where the state and cities spell out the format and timing.

Which office takes your permit in Oregon, and when can you get in-person help?

In Oregon, permits are issued by the local city or county that administers the State Building Code. Most of those jurisdictions use the statewide Oregon ePermitting system for online intake, plan review and inspections; the City of Portland runs a separate system called Development Hub PDX (DevHub) with ProjectDox for plan review, and the City of Eugene uses eBuild. If you are unsure which portal your job falls under, Oregon ePermitting staff can point you to the right jurisdiction by phone at 503-373-7396 (toll-free 1-800-442-7457).

Portland maintains limited counter hours at the Development Services Center, 1900 SW Fourth Ave., Portland, OR 97201. As of September 2026, services are available on Tuesdays and Thursdays, 9 a.m.-3 p.m. during the southbound I-5 closure, with normal 8 a.m.-4 p.m. hours resuming after the closure ends; the main line is 503-823-7300. Eugene's Permit and Information Center is in the Atrium Building, 99 W. 10th Ave., Eugene, OR 97401, and offers drop-in service Monday-Friday, 12-4 p.m. for permit help; general assistance is available by phone weekdays, 9 a.m.-5 p.m.

Core documents every Oregon building permit submittal includes

Application form

Every jurisdiction requires a completed building permit application with the legal site address or parcel number, a work description, project valuation, and contractor or owner information. Portland accepts building permit requests through DevHub and then sets up a ProjectDox plan review; Eugene's eBuild begins with an online intake linked to its Permit and Information Center; jurisdictions on Oregon ePermitting accept applications directly online through their Accela Citizen Access portals. In all three pathways, the application itself is uploaded as a PDF.

Scaled site plan

Oregon requires a site plan showing property lines, the footprint of all existing and proposed structures, driveways, and the distances to property lines. Jurisdictions typically expect a consistent scale (for example, 1 inch = 10 feet or 1 inch = 20 feet) and north arrow, with all easements labeled. Portland's intake pages call out the "site plan" explicitly for residential work; Eugene's residential checklist requires a site plan and has a separate Residential Erosion checklist if ground disturbance is proposed.

Construction drawings (plans)

Plan sets must fully describe the work: architectural, structural, and, where applicable, mechanical, plumbing, and electrical sheets. Oregon's Building Codes Division (BCD) directs that electronic plans be submitted as PDF and remain electronic throughout review. Portland's ProjectDox adds file standards for sheet numbering and requires a third-party-verified digital signature or seal on plans when professional sealing is required. DevHub's file guidance limits individual PDF attachments to 100 MB. The statewide ePermitting program advises separate discipline files and a clear naming convention, such as "020-STRUCTURAL SET.pdf" and "040-STRUCTURAL CALCS.pdf," and to name revisions with "-REV-01" and a short revision narrative as a separate PDF.

Project valuation

Oregon calculates structural permit fees using the ICC Building Valuation Data methodology as adopted in rule. The valuation you enter on the application is confirmed by the building official. Portland publishes its valuation methodology and bases plan review and permit fees on that confirmed figure; Eugene provides an online calculator for its structural plan check fee due at intake.

Energy code compliance

Energy compliance documentation must match the code in effect. For commercial work, Oregon uses the Oregon Energy Efficiency Specialty Code (OEESC) and accepts the state's Oregon Energy Compliance Form. Jurisdictions also accept a COMcheck report aligned with the adopted standard, or an approved energy model. For low-rise residential work under the 2023 Oregon Residential Specialty Code Chapter 11, plans must show thermal envelope details and the required additional efficiency measure; Eugene posts a Residential Energy Additional Measure Selection form for that purpose.

What else gets required based on your site or scope?

Engineering and calculations

When any part of the design is engineered, jurisdictions require structural calculations stamped by an Oregon-licensed professional engineer and uploaded as a PDF. Prefabricated truss designs, hold-down schedules, and connection details appear either in the calcs or as manufacturer sheets. For projects with special inspections under OSSC Chapter 17, Portland issues a special inspections checklist during review and requires the owner or design professional to return a completed special inspections form naming the inspection agency before the permit is issued.

Stormwater and erosion control

Where soil disturbance triggers local rules, you must include erosion and stormwater materials. Eugene's intake includes an Erosion Permit Application and Residential Erosion Checklist when disturbance meets thresholds set by Public Works. Portland's Site Development and Bureau of Environmental Services review stormwater plans; roadway work may be subject to Transportation System Development Charges at the permit stage. The City publishes that some permit-related card payments carry a 3% convenience fee, so agencies encourage ACH or check for larger invoices.

Floodplain and geotechnical reports

Parcels mapped in flood zones require documentation consistent with the local floodplain ordinance, often a separate development permit with elevations and cut-fill quantities. In areas with steep slopes or questionable soils, jurisdictions request a geotechnical report. Eugene posts a "Geotechnical Evaluation Requirements" handout and will condition intake on receiving the report when applicable.

Onsite wastewater and cesspool decommissioning

Where no public sewer is available, the county environmental health authority's onsite wastewater approval or permit number is typically requested with the building submittal. Inside Portland, if a cesspool or other private sewage disposal system exists on site, the city's inspection guidance requires it be properly decommissioned under Oregon DEQ and city rules prior to final inspection, and applicants are asked to address this in their permit documents.

Asbestos and demolition attachments

Oregon DEQ requires an asbestos survey by an accredited inspector before any demolition or renovation of all commercial buildings regardless of age, and for residential buildings built before Jan. 1, 2004. In Portland, residential demolition permits specifically require uploading the asbestos survey and a close-out letter from the licensed abatement contractor before issuance, along with the city's Site Controls Form.

What fees are tied to these documents, and why do cities ask for them?

Two statewide items show up in every Oregon jurisdiction's fee logic. First, a 12% state surcharge is added to building permit fees to fund code administration. Second, jurisdictions assess a plan review fee when plans require review. Portland's published schedule sets the plan review/process fee at 65% of the building permit fee for original submittals, with an additional checksheet fee of $336 per review cycle if more corrections are needed. Nearby jurisdictions using the state model likewise set fire and life safety plan review at 65% of the building permit fee for commercial projects.

Because Oregon fees are valuation-based, your uploaded project valuation directly affects both the permit fee and the plan review fee. Portland also publishes minimum inspection counts by valuation tier and a per-inspection charge when the project exceeds the allowed inspection total for its fee bracket. Eugene notes that if a fee increase occurs after your application is filed, your project keeps the fee schedule in effect at the time of application while the permit stays active, which is why many jurisdictions timestamp the application and payment for plan check at intake.

Other charges can attach to particular documents you upload. Submitting a phased plan review package in Portland adds a per-phase plan review percentage with its own checksheet cap. Uploading a revised set marked "value-added" triggers a plan review calculation on the additional valuation. Where systems development charges apply, cities often collect the SDC estimate once the site plan and preliminary utility sheets are in the file. And in Portland, certain payments processed by card note a 3% convenience fee that does not apply to ACH or check.

How do Oregon's portals handle your files, and what's different between them?

All three commonly used systems in Oregon accept plan and document PDFs, but their file rules and support options differ. Portland's Single PDF Process has a strict file-naming convention and directs applicants to avoid including addresses or permit numbers in file names. Oregon ePermitting encourages discipline bundles and prescribes "REV-01" naming for revisions with an 8.5x11 narrative identifying changed sheets. Eugene's eBuild prompts you for the same core files and backs it up with counter help at set hours.

Key things to know

• Most Oregon permits are filed online. Outside Portland and Eugene, start with Oregon ePermitting; ask the help desk at 503-373-7396 to confirm your jurisdiction's online intake.
• Portland's counter at 1900 SW Fourth Ave. is open Tues/Thurs 9 a.m.-3 p.m. during the I-5 closure; the main line is 503-823-7300. Eugene's Permit and Information Center offers drop-in 12-4 p.m., Mon-Fri at 99 W. 10th Ave.
• Upload the same core set every time: application, site plan, plans, structural calculations if engineered, and energy code documents. Commercial projects add an energy compliance form; low-rise residential projects include an additional-measure selection.
• The statewide 12% surcharge applies to permit fees. Portland sets plan review at 65% of the building permit fee and charges $336 per additional checksheet cycle.
• ePermitting advises discipline-bundled PDFs and "-REV-01" naming on revisions with an 8.5x11 revision narrative. DevHub limits attachments to 100 MB and requires third-party digital seals on plans when a professional seal is required.
• Upload scope-specific documents when triggered: special inspections form (before issuance), stormwater/erosion materials, floodplain elevations, geotechnical reports, onsite wastewater approvals, and, for regulated work, asbestos surveys and close-out letters.
• For many City of Portland payments, a 3% convenience fee applies to credit cards. ACH or check avoids that charge on larger invoices.

Reader Q&A

What exactly must be on the site plan for an Oregon building permit?

Jurisdictions ask for a scaled drawing that shows property lines, all existing and proposed structures, driveways and parking, easements, and setbacks with dimensions. The plan should include a scale such as 1 inch = 10 feet or 1 inch = 20 feet and a north arrow. Portland's residential intake materials and Eugene's residential checklist both call for this same set of details, so the same drawing typically serves zoning, site development, and building review.

Do I need a special inspections document before my permit is issued?

When OSSC Chapter 17 special inspections apply, Portland generates a special inspections checklist during plan review and requires the owner or design professional to return a completed special inspections form naming the agency before the permit is issued. Other Oregon jurisdictions follow the same sequence under the State Building Code. The summary letter from the special inspector is then uploaded at the end of construction before final.

Is an asbestos survey part of the building permit submittal in Oregon?

It is required for certain scopes. DEQ rules require an asbestos survey by an accredited inspector before any demolition or renovation of commercial buildings and of residential buildings built before Jan. 1, 2004. In Portland, the residential demolition application specifically requires uploading the survey and a close-out letter from the abatement contractor prior to permit issuance.

Where do I verify energy code paperwork for my project?

For commercial projects, use the Oregon Energy Efficiency Specialty Code compliance form or an acceptable COMcheck report. For low-rise residential projects, Chapter 11 of the 2023 Oregon Residential Specialty Code applies and jurisdictions require plans to show the thermal envelope plus an additional energy efficiency measure; Eugene posts a dedicated Residential Energy Additional Measure Selection form that satisfies that documentation.

When you assemble your submittal, match the file list to the scope of work and the portal you're using. Portland, Eugene, and Oregon ePermitting each publish the exact PDF types they expect and the order they want them in; checking those pages while you label and upload prevents stalled reviews and extra checksheets.
