Clackamas County Building Permits & Inspections: What to Do in 2026
If you are planning a new home, addition, remodel, deck, electrical upgrade, plumbing work, HVAC installation, solar project or commercial construction in Clackamas County, the first thing to check is not the permit form. It is who actually has permitting authority over your property.
For unincorporated Clackamas County, the county generally handles building permits. Inside an incorporated city, responsibility can be split between the city and county depending on the permit type. Checking this first can save a frustrating application rejection or several days of delay.

Step 1: Confirm Which Agency Handles Your Property
A Clackamas County mailing address does not automatically mean the county issues every permit. The county states that it handles all building permit types in unincorporated Clackamas County, while responsibilities in incorporated cities vary by city and permit category.
Go to the county’s Building Permit Responsibility by Jurisdiction page.
Open Clackamas County CMap and search the street address, tax lot or parcel number.
CMap can identify whether the parcel is within a city and also shows zoning, service providers, natural hazards and other property information.
If the property is incorporated, select the city and check whether structural, mechanical, electrical, plumbing or other permits are handled by the city or Clackamas County.
This type of split responsibility also appears elsewhere in Oregon. If you are researching property outside Clackamas County, our Benton County Building Department guide explains another Oregon county’s permit-jurisdiction process.
What Permits Does Clackamas County Handle?
The correct permits depend on the project. A single project can require several approvals rather than one general “building permit.”
| Project or work | Possible permit or approval |
|---|---|
| New home or duplex | Building/structural, electrical, mechanical, plumbing, planning and possibly septic, erosion or engineering permits |
| Home addition or major remodel | Structural permit plus applicable electrical, mechanical and plumbing permits |
| Commercial construction or tenant improvement | Structural, fire/life-safety and applicable trade permits |
| HVAC, furnace, heat pump or gas work | Mechanical permit; electrical work may require a separate electrical permit |
| Electrical installation or alteration | Electrical permit |
| Plumbing alterations | Plumbing permit |
| Solar photovoltaic system | Building and electrical permits are generally required for a PV installation |
| Manufactured dwelling placement | Manufactured dwelling permit; later additions or alterations may need building permits |
| Excavation or grading | Grading and possibly erosion-control approval |
| Driveway or work in public right-of-way | Development Engineering entrance, right-of-way, utility or development permit |
| Property using an on-site septic system | Septic review or permit may be required in addition to building approval |
Before You Apply: Check Planning and Septic Requirements
One of the easiest ways to lose time is to prepare a complete building plan before checking land-use or septic requirements.
Clackamas County specifically directs building applicants to coordinate with Planning before submission. For partner jurisdictions such as Canby, Gladstone and Molalla, applicable city planning requirements may need to be addressed instead.
If the property uses septic—or your project could affect an existing septic system—check septic requirements early. This is especially important for a new home, replacement structure, bedroom addition, change of use, drainfield work or connection to an existing system.
The county warns that skipping Planning or Septic coordination can substantially lengthen review or cause the application to be rejected during those reviews.
Documents to Prepare for a Building Permit
For projects requiring plan review, expect to provide more than an application form. The exact list changes with project scope, but the county’s current submission guidance identifies several core items.
Site plan
A building permit application generally needs a site plan. Relevant information can include:
- Applicant name and address
- Property legal description and tax lot
- North arrow
- Driveway and adjacent street locations
- Existing and proposed structures
- Property-line setbacks
- Existing wells when the property is not on public water
- Septic tank, drainfield and replacement area when applicable
- Approximate ground slope
- Creeks, streams, ponds, springs or drainage ways
- Relevant elevations around the site and proposed building
You can obtain the property’s tax-lot information through CMap.
Construction drawings and supporting documents
Depending on the job, your package may need floor plans, foundation information, wall and roof framing, elevations, structural calculations, truss information, engineering, energy-code information and other technical documents.
The county’s current electronic-submittal instructions say:
- Documents must be submitted as PDF files.
- Plans must be legible and drawn to scale with correct dimensions.
- Plans and drawings should be in landscape/horizontal orientation.
- Files must follow the county’s Development Direct naming conventions.
For one- and two-family projects, the county also publishes a residential checklist and permit forms covering common plan-review items.
How to Apply for a Clackamas County Building Permit
Projects requiring plan review are generally submitted through Development Direct, the county’s electronic development-services system.
- Confirm jurisdiction. Make sure Clackamas County is responsible for the permit type at your address.
- Identify every permit your project needs. Structural, electrical, mechanical, plumbing, grading, septic and engineering approvals can be separate.
- Check Planning and Septic first. Resolve applicable land-use and on-site wastewater requirements before finalizing plans.
- Prepare the site plan and drawings. Convert required documents to properly named PDF files.
- Open Development Direct. Use Chrome or Microsoft Edge, which the county identifies for access to the system.
- Choose the application type. Building applications can include Building, Electrical, Mechanical, Plumbing, Manufactured Dwelling, revisions and other supported categories.
- Name the project clearly. The county recommends using the property address followed by the work type for building applications.
- Upload every required document. Check the section indicators to make sure each part of the application is complete before submitting.
- Watch your Development Direct account. Reviewer questions, requests for additional material and payment notices appear during processing.
- Download the issued permit and approved plans. Print the approved documents in color and keep them available at the job site for inspections.
Basic Homeowner Electrical, Plumbing or Mechanical Permits
There is an important exception to the normal Development Direct route.
A homeowner doing qualifying electrical, plumbing or mechanical work on their own residence or home-based business may be able to use the county’s Basic Homeowner process when the work does not require plan review.
The county instructs basic homeowner applicants to prepare the appropriate trade application, project description and the property-owner statement when required. These applications can currently be submitted to bldservice@clackamas.us. The county asks applicants to allow up to approximately 48 hours for processing.
Do not assume your project qualifies for the basic process. Additions, significant alterations and work requiring plan review use a different route.
How Long Does a Clackamas County Building Permit Take?
For building applications requiring plan review, Clackamas County currently publishes two useful planning ranges:
| Stage | County-published timeframe |
|---|---|
| Initial pre-screen / intake | Up to 10 business days before the project is set up in the system |
| Plan review | Approximately 3–7 weeks depending on project complexity |
Those are not guaranteed approval dates. Missing information, Planning or Septic issues, engineering corrections, applicant resubmittals and more complex projects can add time.
The practical way to avoid unnecessary delay is simple: check jurisdiction first, resolve land-use and septic questions before submission, and upload a complete plan set the first time.
2026/2027 Clackamas County Building Permit Fees
There is no single flat price for a Clackamas County building permit. Structural fees can depend on project valuation, and separate plan-review, trade, state and development-related charges may apply.
The county’s current 2026/2027 Building Division fee schedule lists the following residential structural permit tiers for new construction, additions, remodels and alterations:
| Project valuation | 2026/2027 structural permit fee |
|---|---|
| $1–$500 | $123 |
| $501–$2,000 | $123 |
| $2,001–$25,000 | $123 + $7.40 per $1,000 over $2,000 |
| $25,001–$50,000 | $298 + $6.72 per $1,000 over $25,000 |
| $50,001–$100,000 | $471 + $4.48 per $1,000 over $50,000 |
| Over $100,000 | $701 + $3.75 per $1,000 over $100,000 |
The regular residential plan-review fee is listed as 65% of the building permit fee.
Other useful 2026/2027 figures include:
- Reinspection fee: $123
- Residential Certificate of Occupancy: $43.50
- 1- and 2-family mechanical minimum permit fee: $123
- Plumbing minimum permit fee: $123
- Additional plan review caused by changes or revisions: $123 per hour, with a one-hour minimum
- Inspections outside normal hours: $123 per hour plus overtime, with a four-hour minimum
These figures do not mean that the listed building permit fee will be your total project cost. Planning charges, trade permits, erosion control, system development charges, school construction excise tax and other fees can apply.
For a new single-family home in unincorporated Clackamas County, use the county’s official new-home fee estimator. It is an estimate only, not a final quote.

How to Search a Clackamas County Permit or Property Record
You can use the Citizen Access system to check permit history, application information, inspection activity and available approved documents.
- Open Clackamas County Citizen Access.
- Select Building and then the search option.
- Start with the property address or known permit number.
- If an address search produces too many or no results, simplify the search rather than filling every available field.
- Open the matching record to review available permit, document and inspection information.
The county specifically recommends a “less is more” approach when searching—starting with the address can be more effective than entering many fields at once.
If you cannot locate an older permit or need help understanding the record, contact Building Codes at 503-742-4240.
Which Oregon Building Codes Apply in Clackamas County in 2026?
Oregon adopted several new specialty-code editions that affect 2026 construction. Which edition applies can depend on the permit date, project type and an applicable phase-in period.
| Code | Status in October 2026 |
|---|---|
| Oregon Residential Specialty Code | 2026 ORSC Chapter 1 became mandatory October 1, 2026. Construction provisions entered a phase-in period; the 2026 construction provisions become mandatory April 1, 2027. |
| Oregon Structural Specialty Code | 2025 OSSC became mandatory April 1, 2026. |
| Oregon Electrical Specialty Code | 2026 OESC became effective October 1, 2026 and is based on the 2026 National Electrical Code. |
| Oregon Plumbing Specialty Code | 2026 OPSC became effective October 1, 2026 and is based on the 2024 Uniform Plumbing Code. |
| Oregon Mechanical Specialty Code | 2025 OMSC became mandatory April 1, 2026. |
| Oregon Energy Efficiency Specialty Code | 2025 OEESC became mandatory July 1, 2025 for applicable commercial construction. |
During the 2026 residential code transition, do not assume the newest construction chapter automatically controls every already-filed project. Confirm the applicable code with the permit office when designing, revising or resubmitting plans.
You can review Oregon’s current editions through the Oregon Building Codes Division adopted-codes page.
For another example of how Oregon’s 2026 specialty-code changes affect a local permit department, see our Bend Building Department guide.
Clackamas County Design Criteria Worth Checking Early
Code compliance is not only about choosing the correct codebook. Site conditions can affect structural design.
Clackamas County’s published structural criteria identify:
- Seismic Design Category: D under the listed OSSC criteria.
- Wind: design speed and exposure depend on project risk category, location and whether the site is in a special wind region.
- Presumptive soil bearing: published county criteria include 1,500 psf for the listed soil condition when a project-specific geotechnical report is unavailable.
- Snow load: site-specific county snow-load criteria must be checked.
- Frost protection: minimum footing depth increases with elevation.
| Site elevation | Published minimum frost depth to bottom of footing |
|---|---|
| Below 2,500 ft | 12 inches |
| 2,500–4,000 ft | 18 inches |
| Above 4,000 ft | 24 inches |
Use the county’s current design criteria page before final structural design. A general county value does not replace project-specific engineering where engineering is required.
Solar Permits in Clackamas County
For a photovoltaic solar installation, Clackamas County states that both building and electrical permits are required.
Prescriptive roof-mounted systems that meet county criteria follow a simpler building-permit path. Ground-mounted systems, high-wind or high-snow sites, flood-hazard locations, heavier systems and other non-prescriptive installations can require engineered design and longer review.
Before buying equipment based only on a contractor quote, check the county’s official solar permit requirements.
Common Problems That Delay a Permit
| Problem | Practical fix |
|---|---|
| Applied to the wrong jurisdiction | Check CMap and the county’s permit-responsibility page before filling out forms. |
| Planning requirements were not checked | Resolve zoning, land-use and setback questions before preparing final construction plans. |
| Septic system affects the proposed work | Contact county septic staff before design and permit submission. |
| Site plan is incomplete | Show structures, property lines, setbacks, access, slope, wells, septic and drainage features where applicable. |
| PDF files are hard to review | Use legible, scaled, correctly oriented files and follow Development Direct naming rules. |
| Applicant misses reviewer messages | Check Development Direct regularly for comments, fees and resubmittal requests. |
| Work is covered before inspection | Schedule required rough inspections before drywall, concrete or other finishes conceal the work. |
| Building final is requested too early | Complete required electrical, plumbing and mechanical finals first. |
A Simple Permit Checklist Before You Start
- Confirm the property jurisdiction.
- Check zoning and land-use requirements.
- Confirm whether septic approval is involved.
- Identify structural and trade permits separately.
- Prepare an accurate site plan.
- Prepare legible, scaled construction drawings.
- Use the current Oregon specialty-code edition applicable to the project.
- Submit through the correct county system.
- Watch for plan-review corrections and fee notices.
- Do not begin regulated work until the necessary permit is issued.
- Keep approved drawings at the site.
- Schedule each inspection before work is concealed.
- Complete trade finals before requesting the building final.
If your project is actually in another Oregon city, the process can be very different even though statewide specialty codes are similar. For example, our Ashland Building Department guide explains Ashland’s separate permit and inspection system.
