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
Approximately 7-10 business days for residential permits and 10-14 business days for commercial permits, assuming complete submissions.
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 913-715-2200 (Option 1 for permits); 913-715-2200 general Building Codes; 913-715-2204 Building Official 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
Johnson County Planning, Housing and Community Development - Building Codes is the identified county-level authority for this profile. Confirm that the property is in its service area 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 913-715-2200 (Option 1 for permits); 913-715-2200 general Building Codes; 913-715-2204 Building Official.
Approximately 7-10 business days for residential permits and 10-14 business days for commercial permits, assuming complete submissions.
All county building permits require inspections. Submit requests through MGOConnect or call 913-715-2200; approved plans must be on site. Concrete inspections require at least 2 hours’ notice on the day of the pour; other inspections require at least one-half day’s notice. Only concrete and homeowner-occupied projects receive set times. Inspection requests also may require prior entrance-permit and septic/environmental final reports before final building inspection.
For unincorporated Johnson County in 2026, the county’s 2018 Code of Regulations adopts the 2018 International Residential, Building, Fire, Mechanical, Plumbing, Fuel Gas, Energy Conservation, Existing Building, Swimming Pool and Spa, and Property Maintenance Codes, plus 2009 ICC A117.1, 2014 ICC 500, and NFPA 70 (National Electrical Code 2017). The county also publishes project-specific amendments and requirements. Minor repair and maintenance such as carpeting, painting, wallpaper, replacement of receptacles, replacement of previously installed fixtures, vanities, and cabinetry generally does not require a permit. A residential accessory building under 200 square feet does not require a building permit, although setback rules still apply. A residential or commercial fence under 7 feet does not need a building permit, but Planning must be contacted for area-specific requirements. All decks, roofs, new structures, and most enlargement, alteration, repair, moving, demolition, and trade-system work require permits.
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.
