RESIDENTIAL ALTERATIONS/ADDITIONS

Do I Need A Permit for My Project?

Each municipality varies by price and type of project as far as what is required for permitting, but you can assume that any project that changes occupancy, area, structural strength, fire protection, exits, light or ventilation is going to need a building permit.   

To be certain, we encourage you to email our office with the details of your project, the cost associated with it (RS Means), and your address.  That way, you will not find yourself in a non-compliant building situation and at risk of fines. 

I  Need a Permit...Now What?

Please follow the steps below to obtain the necessary

documents to submit for your residential alteration/addition.

  • Filled out in its entirety, signed, and dated.

  • Please include this if you need more room than what the application allows for

 

  • We must have this for homeowners doing their own work or hiring a contractor that does not have a valid Dwelling Contractor Qualifier License in the State of WI.

 

Copy of your plans

  • They can be hand drawn but please include room sizes, door sizes, and window sizes.

 

Copy of a Sanitary Permit or Occupancy Affidavit

  • If you are adding a bedroom, you will also need to provide us with a copy of your sanitary permit showing how many bedrooms your septic is rated for. 

  • If adding a bedroom puts you over your septic rating, you will need to obtain an Occupancy affidavit and provide us with a copy of that.  You can obtain either from County in which the work is being done.

CSM (Certified Survey Map) or Plat Map showing setbacks

  • Obtain from the county

 

  • If you are adding on to your house or adding anything on your property where nothing existed,  (i.e. changing the footprint) we need a detailed site plan showing setbacks, etc.

 

Land Use From County

  • Pierce County-must obtain a Land Use from the county (with the exception of the Town of River Falls, the Village of Elmwood, the Village of Spring Valley, or the Town of Ellsworth ETZ zone ) if you are adding anything outside of the walls of your home

  • St. Croix County-needed if you are near wetlands, drainage easement, etc. *If it is questionable, we require documentation stating that it is not required.
