All moved structures require a building permit through Whatcom County Planning and Development Services.
A Building permit is required to construct a new foundation under an existing or moved building.
Pre-move inspections are not required for legally established structure located within Washington State.
All structures that are moved from out of State or out of Country (Canada) require a pre-move inspection performed by a Washington State licensed Engineer. The pre-move inspection form may only be obtained from the Planning and Development Office.
Once the pre-move inspection has been completed and the building has been approved to be moved, you may apply for a building permit to move your structure.
Elevation drawings showing all 4 sides of the building (labeled North, East, South, and West).
Plans should be 1/4 inches = 1 foot scale.
Elevation views are needed to show the shape of the building, height, number of stories, and any covered porches or decks.
Pictures of all 4 sides may be submitted in lieu of drawings
Provide verification of roof framing as “engineered trusses” or “stick framed roof” so it can be determined how roof loads are/will be transferred to the foundation (i.e. full span trusses or stick framed roof that relies on interior walls for support.)
Provide an as-built floor framing plan.
Provide an as-built foundation plan and a new foundation plan
Show perimeter foundation and interior pad or strip footings.
Show size and location of access and vents.
Provide new foundation details for perimeter foundations and all pad footings.
Indicate dimensions, reinforcement, mudsills, anchor bolts, post to beam and footing connections.
Show floor insulation and vapor barrier.
Indicate how the existing floor framing will be positively connected to the new foundation at mudsills.
The Washington State Energy Code requires installation of R-30 insulation in the floor and 6 milliliters black plastic vapor barrier in the crawl space.
Smoke detectors must be installed in accordance with International Residential Code (IRC) 313.1 as well as carbon monoxide detectors in the existing buildings.
Depending upon the complexity of the project, additional information may be required. (I.E. if the structure has to be cut into multiple sections to be moved)
If the interior is to be remodeled or there will be additions to the moved structure, additional permits may be required.
