Summary

Unincorporated Washington County protects designated monuments, statuary and other cultural objects through a Historic and Cultural Resource Overlay District applied by plan amendment. Owners of a designated resource need a Type II permit even for exterior alteration and a Type III permit to relocate or demolish it.

City-specific rules exist: Hillsboro, and Beaverton have their own historic-cultural monuments rules that differ from Washington County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Object. The term object is used to distinguish from buildings and structures those constructions that are primarily artistic in nature or relatively small in scale and simply constructed. Although it may be, by nature or design, movable, an object is associated with a specific setting or environment, such as statuary in a designed landscape. Examples: sculpture, monuments, mileposts, boundary markers, statuary, and fountains. ... No development permit shall be issued for exterior alteration, relocation or demolition of any designated resource or any potential resource which is under consideration for designation while a public hearing or any appeal thereof is pending.

Full Breakdown

Section 373 of the Community Development Code creates the Historic and Cultural Resource Overlay District. 3 defines the 'Object' category the district protects as constructions 'primarily artistic in nature or relatively small in scale and simply constructed,' giving sculpture, monuments, mileposts, boundary markers, statuary and fountains as examples, distinct from buildings and structures. 1, either a quasi-judicial Type III action initiated by the property owner, the Board, the Planning Commission or the Director, or a legislative Type IV action any individual may request. A through C.

1 bars any development permit for exterior alteration, relocation or demolition while a designation hearing or appeal is pending. 4. 9 covering structural capacity to move, documented efforts of at least 90 days to find a relocation buyer, and confirmation the Washington County Museum or another preservation group was offered a chance to salvage the resource. 772(3), though the underlying designation stays on record until formally removed under Section 373-11.

Violations & Fines

Exterior work, relocation or demolition of a designated cultural resource without the required Type II or Type III permit is a Code violation the county's Land Use Division can enforce through permit denial, stop-work action and the county's general code enforcement process; a pending designation hearing or appeal under Section 373-6.1 independently blocks permit issuance regardless of any other violation.

Frequently Asked Questions

Does a monument have to be on the county inventory before this overlay applies?
Yes. Section 373-4.2 has the Review Authority apply the Historic and Cultural Resource Overlay District to resources listed in the Washington County Cultural Resources Inventory, and the overlay only attaches through a Plan Amendment process under Section 373-4.1. An object not on the inventory and not run through that plan amendment is not subject to Section 373.
Can I get out of the designation if it costs too much to maintain?
Section 373-4.3 lets an owner demonstrate economic burden with evidence such as two independent appraisals of value with and without the resource, insurance broker estimates, and rehabilitation contractor estimates. If the Review Authority or Appeal Authority accepts that showing, it may decline to permanently apply the overlay, though it can still apply it temporarily for up to 180 days while the county explores ways to protect the resource.
What has to happen before a designated resource can be demolished?
Section 373-6.7 requires a Type III procedure, and Section 373-6.9 requires findings that the resource cannot be moved due to structural inadequacies, or that the owner documented at least 90 days of effort to find a relocation site, plus proof the Washington County Museum and another appropriate preservation organization were offered the chance to salvage and record the resource.
