DECKS

STOP!

Does your "deck" have a roof?

   Then it is NOT a deck, and this is not the information you need.

Please see the Addition/Porch/Attached Garage page.

Did You Know?

Any deck, whether connected to a structure or free-standing, that serves as an exit must meet the standards of the WI Uniform Dwelling Code SPS 321.255 (1). 

Chapters SPS 320 to 325 

WI UDC-DECK INFORMATION

Appendix B

The following documents create a deck application. Please use in conjunction with the Deck Application Required Document Checklist at the bottom of the page.

 

1. Residential Addition Building Permit Application

Filled out in its entirety, signed, and dated.

2. Cautionary Statement 

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.

3.  Land Use/Zoning/Conditional Use Permit, If Needed

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 structure use or  structure location due to 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.

4.​ Site Plan

Please fill out completely, notating the actual distance from the structure to lot lines.  You may use a copy of satellite map or plat map or CSM as long as the structure is clearly marked and identified with the setback distances labeled.

5. CSM or Plat Map 

Obtain a CSM or Plat map from the Register of Deeds at the County, if available. (You will find your setback information on this.)  If one is not available for your property, you may  need to contact the zoning administrator to see what the property is zoned and what your setbacks are. If your project is zoned by Pierce County,  this is provided on your Land Use Permit. 

6. Deck Plans 

These can be hand drawn but should include a side view and a top view of the deck including dimensions, beams, joists, construction materials etc. 

 

7. Design Load Specifications Must Include one of the 2 options below

Option 1:  Design load calculated and stamped by a registered engineer. (PLEASE NOTE:  We can not accept deck plans alone from your local home improvement store unless they are accompanied by the worksheet or engineered calculations.  These stores do not provide engineered calculations.)  

Option 2: The WORKSHEET at the end of Appendix B  SPS 325 filled out and showing compliance with the standards in Chapters SPS 320 to 325 APPENDIX B and Appendix C, if applicable.  (PLEASE NOTE: These standards do not account for privacy screens, planters, built−in seating, hot tubs, stairs for multiple− level decks, etc. Engineering analysis is needed for decks with these designs.
