2. No General Business License Required in Cedar Rapids

   Cedar Rapids Development Services does not issue an annual business license. Development Services and Building Services handle zoning, building and trade permits, and Certificates of Occupancy — required when you build, remodel, or change the use of a space, not as a recurring license. The City Clerk licenses only narrow categories: alcohol and tobacco, transportation, vendors, after-hours businesses, business close-out sales, and pawnbrokers. Otherwise your obligations are your state trade license (for example cosmetology or contractor registration) and a Certificate of Occupancy if you take over or change commercial space.

3. Cedar Rapids Plumbing Permit (per project)

   A separate plumbing permit must be pulled from the City of Cedar Rapids Building Services Department (Building and Trades Division) for each job, and a city plumbing inspection is required when the work is finished. The permit is pulled by a contractor holding the matching Iowa plumbing license. Starting work without a permit can add an investigation fee on top of the permit fee.
