Detached Garages, Sheds, Outbuildings

All-Croix Inspections issues outbuilding, shed, and detached garage permits for all of our contracted municipalities EXCEPT* in the towns of Erin Prairie, Eau Galle, Hartland, Maiden Rock, Martell, River Falls, Salem, and Union.

*Please Note:  Though All-Croix Inspections does not issue permits for outbuilding in these municipalities, you may still need a land use permit and/or a building permit from the municipality. Contact your municipality.

Outbuilding Application Process
Follow the steps below.  Use the Checklist for Outbuilding Applications for additional guidance.


 1. Complete the following documents: 

a. Residential Outbuilding Permit Application

b. Cautionary Statement

c. Building Cross Section 

d. Site Plan

e. Subcontractor List


2. Obtain a Land Use/Zoning/Conditional Use Permit, If Needed.  (Note: A Land Use or Zoning permit is NOT the same as a building permit.)

It is up to the applicant to make sure that all zoning regulations are being followed.  This includes, but is not limited to, making sure there are not restrictions on what you intend to use the structure for, how many structures are allowed, the height of a structure, and the physical landscape of the lot (i.e. slopes, ponds, rivers, easements, protected areas....) Your building permit only addresses construction codes etc.  Anything relating to the above is outside All Croix's responsibility.   If you are unsure who to contact about zoning,  click here.

3. Obtain a CSM or Complete Plat Map from the Register of Deeds at the County if available. If you are in a development, then there will a plat map available. You will find your setback/easement restrictions on this.  It may be more restrictive than the general zoning code.  We need the recorded document. (You may find your setback information on this and any easements etc.)  If one is not available, you will need to contact the zoning administrator to see what your setbacks are. 

4. Obtain a Sanitary Permit from the County, if applicable.

Are you building a shed

 or an outbuilding with living quarters?

Any structure that a person sleeps in (even occasionally) is a dwelling and must be permitted like one.  Please see the process for that here.
