Summer Project Permits
With summer just around the corner it is a great time for building projects. Whether you want to build a new shed for all your lawn care equipment or to install a nice cool pool for the kids in the back yard, we can help by making sure it is a safe structure per our city ordinance and codes.
The Checklists below are what we look for when summer projects are in the process of being built.
Before any projects are started a Building/Zoning Permit is required. Once the application has been received, our inspectors will conduct a plan review. Once the plan review tasks are completed and the permit is paid in full, we will issue your building permit to start building your project. You cannot start a project without requiring a permit. If you have any questions feel free to contact us at the office.
