When does a window replacement need a permit in Kirkland?
In-kind window/door replacement is exempt when no structural members are altered, the U-value meets the prescriptive energy code, safety glazing and fall protection are provided where required, and egress is maintained. A new or enlarged opening requires a permit. KMC 21.06.215(1)(N) exempts "In-kind window replacement for IRC structures where no alteration of structural members is required, safety glazing is provided where required, window fall protection is provided where required, emergency egress requirements are provided and when the window U-values meet the current prescriptive requirements of the International Energy Conservation Code." None of this is exempt in a flood hazard area, a critical area or its buffer, or where the International Wildland-Urban Interface Code applies. KMC 21.06.215: "Permit exemptions shall not apply to areas of flood hazard or city land use critical areas and their required buffers, or locations subject to the construction requirements of the International Wildland-Urban Interface Code."
