Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

Project questions
Johnson County Planning, Development and Sustainability / Building Services 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 319-356-6085 (Building Services); 319-356-6083 (Planning and Development).
N/A for ordinary building permits. The county publishes 7-10 business-day estimates for certain complete site-plan reviews after corrections and requested information are submitted; complex zoning, conditional-use, rezoning, stormwater, or public-hearing matters can take longer. Permits must begin within 180 days of issuance and may not be suspended or abandoned for more than 180 days without an extension.
Apply through the CitizenServe portal, upload the PDF building plans and required application materials, pay fees, and use the portal to request/schedule inspections. Building Services conducts site inspections; applicants must coordinate inspections before relevant work is covered and contact staff with questions at 319-356-6085. New homes and commercial buildings also need a wastewater permit from Johnson County Public Health where applicable. Demolition and trade work have separate application requirements.
Johnson County’s published FAQ identifies the 2024 International Residential Code, 2024 International Building Code, 2023 National Electrical Code as adopted by Iowa, 2024 International Mechanical Code as adopted by Iowa, 2024 Uniform Plumbing Code as adopted by Iowa, and 2012 International Energy Conservation Code. The county also enforces its Unified Development Ordinance, site-plan, stormwater, erosion and sediment control, sensitive-area, floodplain, and other applicable land-use requirements in unincorporated areas. A permit is not required for a one-story detached accessory structure of 200 square feet or less used as a tool shed, storage shed, playhouse, or similar use; additions to a house require a permit regardless of size. Window replacement is exempt when headers are not moved/altered/replaced, subject to emergency-escape-opening requirements. A detached deck may be exempt when it is no more than 200 square feet, no more than 30 inches above grade, unattached to a dwelling, and does not serve the main exit door. Construction of decks otherwise requires a permit.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
