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. Plan review is 65% of the building permit fee. The city does not enforce residential electrical/plumbing code, applicants must obtain those separately from Malheur County. Oregon is a state-adopted code jurisdiction, cities cannot amend ORSC/OSSC.
