Permits Required
The following permits are typically required to demolish a building in Wisconsin. Actual requirements vary by municipality.
Demolition Permit
Required before demolishing any building or structure in Wisconsin. Municipalities require demolition permits to manage asbestos abatement, utility disconnection, stormwater runoff, and debris disposal. Structures in historic districts may require additional review under local preservation ordinances or the Wisconsin Historical Society.
Inspection required after work is completed.
Razing Permit
A specialized permit used in some Wisconsin municipalities (notably Milwaukee) as the formal authorization for complete building removal. The razing permit process may include additional requirements beyond a standard demolition permit, such as a site restoration plan, escrow deposit, and a timeline for completion. In Wisconsin, 'razing' specifically refers to the complete removal of a building down to the foundation.

Frequently Asked Questions
Do I need a permit to demolish a building in Wisconsin?
Yes. Wisconsin municipalities require a demolition or razing permit before any building or structure can be torn down. Some cities use separate permits for partial demolition vs. complete razing. The permit process requires proof of utility disconnection, asbestos inspection results (for commercial buildings and multi-family residential), and a plan for debris disposal and site restoration.
Is asbestos testing required before demolition in Wisconsin?
Wisconsin requires a certified asbestos inspection before demolishing or renovating any commercial building or any residential building with more than four dwelling units. Owner-occupied single-family homes are exempt from the state requirement, but many municipalities require testing regardless of building type. If asbestos is found, a licensed abatement contractor must remove it before demolition begins.
Can I demolish my own garage or shed without a permit?
Most Wisconsin municipalities require a demolition permit for any structure, including detached garages. Some exempt very small accessory structures under 120 square feet, but this varies by city. Even when a permit is not required for the structure itself, you must still properly disconnect any utilities, manage debris disposal, and may need an erosion control plan if the site is disturbed.
