Building Department

Waterloo Building Department 
The Waterloo Building Department administers all matters related to commercial and residential construction as well as the enforcement of building codes through education, plan review, permitting and inspections.  The Waterloo Building Department encourages you to contact us when considering a building project. Residents are reminded that if they are hiring a contractor to do work, that their contractor should be taking out the required permits.

Residential Contractor:
The Waterloo Building Inspection Department offers Residential Contractor Exams for those who want to become a licensed residential contractor with the City of Waterloo.

Exams will be given for one week each month during business hours. Two applicants per day will be scheduled. Exam time is 8:00 am on your designated day. The exam will be given at the Building Department located on the second floor of City Hall.

Select a day of the week that best suits your schedule on the application which can be accessed by clicking the link below. Applications along with the $50 registration fee must be received one week prior to your exam date.


Commercial Contractor:
When submitting plans for a commercial plan review, please provide two full sets, signed and sealed.  These will be internally distributed for review between the Building Department, Planning & Zoning, Engineering Department and Fire Marshall’s office.


For new construction, a site plan is required.  For new construction over 5000 square feet, civil plans are required along with SWPPP plans and application.

If the project is a food and or alcohol establishment, please submit a set of construction documents to the Black Hawk County Health Department.  Call 319-291-2413 with questions.
