What types of projects are considered RESIDENTIAL ALTERATIONS?
​
RESIDENTIAL ALTERATIONS are any projects within a dwelling that are confined to the existing footprint of the dwelling.
​
Some examples include:
​
Electrical Service Upgrade
Enlarging/Adding Windows and/or Doors
Adding a Fireplace
Kitchen Remodel
Bath Remodel
Basement Finish
​
These are just a few of the projects that are considered residential alterations.
​
-
Gather required documents #1- #5 (see below) to make complete application packet.
​​
-
Submit complete application packet via email to office@allcroix.com. You will be sent an email back stating it was received. You can also drop it off in the office during Walk-in Office Hours. (See the Contact Us page for details.)
-
Wait patiently for permit application to be reviewed. The review process may take up to 10 business days to complete. (This timeline is dictated by state code and the countdown starts upon the receipt of a complete packet.) Plan accordingly.
-
Pick up and pay for your permit. When your permit is ready for payment, an email will be sent with the cost and instructions on paying if you are in a township. If you are building in a City or
Village, the City or Village will contact you for payment and pick up.

Do I Even 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.
​
​
What IS RS Means?
RS Means is a division of Reed Business Information that provides cost information to the construction industry so contractors in the industry can provide accurate estimates and projections for their project costs.
There are other free websites that can also help you evaluate the cost of your job.

​
PLEASE NOTE: WE CANNOT ACCEPT SINGULAR DOCUMENTS THAT DO NOT COMPRISE A COMPLETED APPLICATION.
1. Residential Building Alteration Permit Application
Filled out in its entirety, signed, and dated.
​
Please include the name, contact details, and license numbers of the subs you are hiring. Sub-contractors must be licensed in Wisconsin.
​If you are the homeowner applying for the permit, you must sign and submit the cautionary statement.
4. Floor Plans
Floor plans can be hand drawn but please include labels with room use, room sizes, door sizes, and window size.
​Remodels require both a BEFORE and AFTER floor plan.
Remember, if you are adding any square footage to your home, you are actually doing an ADDITION and should follow the Addition/Porch/Attached Garage procedure located here.
​​
5. Copy of a Sanitary Permit or Occupancy Affidavit
(Not applicable if you have municipal water and sewer.)
If you are adding a bedroom or finishing 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 from St. Croix County in or a Per Capita Flow Statement (whichever County the project is located in.)
