Full Breakdown
Under MCC § 39.8450, a building, structure, or premises the county has classified HP under §§ 39.5100 through 39.5170 cannot be torn down on demand. An application to remove or demolish it is a Type IV land use decision: the Planning Commission holds a public hearing and recommends either preservation measures (purchase, trade, relocation, or an approved change of use) or removal, and the Board of County Commissioners then holds its own de novo hearing and makes the final call. The Building Official cannot issue the demolition permit until 120 days after filing unless the Board authorizes it sooner. This applies only to unincorporated county land. Portland, Gresham, Troutdale, Fairview, and Wood Village enforce their own separate preservation rules.
Violations & Fines
Demolishing or materially altering an HP-designated building without going through this review is a zoning violation under MCC § 39.1510, exposing the owner to a Notice of Violation, fines, and required corrective action under the county's Enforcement Code.
