Roof Replacement Permit Requirements in Ontario, OR
Ontario's Building Department (Building Official Eddie Alvarez) enforces the Oregon Structural Specialty Code (OSSC) and Oregon Residential Specialty Code (ORSC) for structural, mechanical, manufactured dwelling, and solar permits. 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.
