How are inspections scheduled?
Schedule an appointment with Land Development at https://login.nowaitinside.com/booking/4vFUW9wWed9K81H1xHcval9b or call 785-828-3347. The application documents entrance review and wastewater/floodplain review; the owner must contact Land Development when the project is complete to obtain a Certificate of Occupancy. A wastewater inspection for property outside city boundaries costs $150, and septic tanks must be pumped at the time of inspection.
Which codes and exemptions should I review?
N/A; the permit form requires work to conform to current codes and regulations adopted by Osage County, but the county does not identify a specific structural building-code edition on its Land Development page, permit form, or zoning regulations. The current county form states that all construction and all buildings moved onto property require a building permit, whether or not the project is farm-exempt. A farm building may be classified as exempt when it is on at least 40 acres and used for qualifying agricultural purposes, but the permit filing is still required. The form also covers interior and exterior remodeling; no general cosmetic/minor-work exemption is published.
