Start with jurisdiction and project scope
Before applying in Clackamas County, confirm whether the property is within city limits or in unincorporated county territory. Describe the complete work to the office serving that parcel, including electrical, plumbing, structural, and site changes. Building, zoning, utility, and private HOA approvals can be separate.
Open the local official sources or prepare a project checklist.

Solar Permits
Clackamas County photovoltaic projects require both building and electrical permits, with prescriptive and non-prescriptive building permit paths.
Permit and scope questions
Clackamas County says solar photovoltaic installations require both building and electrical permits, with electrical permits requiring inspections but not plan review.
Zoning and placement
Solar systems that qualify as an accessory use are allowed in all land-use zones when annual power-generating capacity is limited to power consumed by the property; larger systems may require land-use review.
Building and trade review
Building permits for solar PV systems are divided into prescriptive and non-prescriptive categories, and the checklist determines whether a project qualifies as prescriptive.
Discuss your project early when: Call before applying if the system may exceed accessory-use limits, the project is ground-mounted, the roof structure is uncertain, the system is non-prescriptive, or electrical service changes are included.

Deck, Septic, and Inspection Planning
Clackamas County deck planning should account for Oregon's 30-inch deck permit threshold, septic tank and drainfield setbacks, and county inspection timing.
Permit and scope questions
For Clackamas County, ask the permit office to confirm the height or depth limit and the grade or reference point used for measurement; whether attachment, a roof, stairs or required exit access changes the deck review; and the setbacks, easements and public-space constraints for the parcel before treating this project as exempt or permit-required.
Zoning and placement
Ask Clackamas County's planning or zoning office to check whether attachment, a roof, stairs or required exit access changes the deck review for the proposed site and use.
Building and trade review
Residential inspections include site inspection with footing inspection, footing inspection before concrete, and other stage inspections depending on the approved work.
Discuss your project early when: Contact Clackamas County before ordering materials or starting work to resolve whether attachment, a roof, stairs or required exit access changes the deck review. Bring the proposed dimensions, location and scope so the answer is tied to the project.
