Per the City of Ontario Building Department Fee Schedule (Resolution 2024-114, effective 11/18/2024), ELECTRICAL and PLUMBING permits are issued and inspected by the Malheur County Building Department (316 NE Goodfellow St, Ontario, OR 97914; (541) 372-5460), not the City of Ontario. Online permitting is through Oregon ePermitting (Accela). Residential structural permit fees start at $40 minimum; commercial at $76 minimum. State surcharge is 12% of the building permit fee.

When you don’t need a permit
Tree removal is not regulated by the building code. Check with Ontario Planning & Zoning (541) 881-3238 or Public Works for any local tree ordinance, especially for street trees in the public right-of-way. A building permit is not required under 2021 ORSC.
Zoning & HOA Considerations
Many cities protect trees above a certain diameter at breast height (DBH), commonly 6", 12", 19", or 20", and some cities protect specific species (oak, sycamore) regardless of size. Portland, Atlanta, Austin, Seattle, and Los Angeles all have significant tree protection rules. Houston and most of Texas have none.
If you live in an HOA community: hOAs commonly regulate tree removal, particularly for front-yard trees and specimen trees. Even where city law permits removal, HOA approval may be required.
