The Coos County Building Department, part of Community Development, runs a full building codes program. Its structural inspector covers the whole county except the Cities of Coos Bay and North Bend. Septic permits and inspections are handled by the county’s own Onsite Septic Program, to which DEQ has delegated the program.
This guide covers the county program and its septic, floodplain and road offices. The county’s pages disagree on which areas get county plumbing and electrical inspections and on walk-in days, so both versions are given below; confirm with the county.
What requires a building permit in Coos County?
Land use authorization must accompany every permit request, including electrical and plumbing. Properties without municipal sewer need an onsite system permit from the county.
Oregon’s building code and its exemptions are the same in Coos County as everywhere in the state, and an exemption from the building permit is not an exemption from zoning, land use or a trade permit. Site snow, wind and seismic values come from the state’s Oregon Design Criteria Hub. How Oregon’s statewide code works

The county’s pages describe its reach two ways. The Building Department page says county inspectors do plumbing and electrical inspections for all of Coos County. The homeowner guide says Coos County issues all building permits except structural and mechanical inside North Bend or Coos Bay, and handles electrical and plumbing everywhere except the City of Lakeside, which has its own building department (541-759-3009).

Coos County permit costs and fees
Coos County’s land use fees (effective 7/1/26, Order 26-06-021L) list a floodplain review without a notice of decision at 546.00 dollars, or 955.00 with one, and a rural address at 241.00.
Oregon fixes the method rather than the price: new construction is valued with the ICC building valuation data under OAR 918-050-0100, Coos County applies its own schedule, and a 12 percent state surcharge is added to every permit fee. How Oregon permit fees are set
