Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
N/A for unincorporated county building work; municipal timelines vary.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call 573-642-0737 (County Commission); 573-642-0740 (Road and Bridge Engineer); 573-491-1118 (sewage ordinance contact); 573-592-2480 (floodplain contact) if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 573-642-0737 (County Commission); 573-642-0740 (Road and Bridge Engineer); 573-491-1118 (sewage ordinance contact); 573-592-2480 (floodplain contact).
N/A for unincorporated county building work; municipal timelines vary.
No county building-inspection process applies to unincorporated areas. Contact the applicable municipality for building inspections. For separate county-regulated matters, call the sewage ordinance contacts at 573-491-1118, the floodplain contact at 573-592-2480, or the Road and Bridge Engineer at 573-642-0740 for utility right-of-way permits.
N/A for unincorporated Callaway County. The official county page states that Callaway County has not adopted planning or zoning and that no building or occupancy permits are required in unincorporated areas. Incorporated Fulton, Holts Summit, Lake Mykee, New Bloomfield, Mokane, Kingdom City, and Auxvasse may have their own local requirements. All building and occupancy work in unincorporated Callaway County is outside a county building-permit requirement according to the county's current 2026 planning notice. Sewage, floodplain, and county-road right-of-way requirements remain separate; incorporated municipalities may require permits for work within their boundaries.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
