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.

Preconstruction meetings can held upon request on Tuesday mornings at 9:00 a.m. in the Mollenhoff Room on 2nd floor of City Hall. These can be requested to discuss upcoming commercial projects by the owner, developer or contractor.  

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:
