Permit needs for five common La Crosse projects
The city's own packets settle three of the five common jobs. The other two aren't confirmed here, so the city has the answer.
Roof replacement
Yes. Many cities require a building permit for re-roofing, so check with the city permit desk before you start.[2]
Skip the generic online claims that a reroof never needs one. The city's packet is the authority for a La Crosse address.
Deck
Yes. The wood deck packet gives the same answer: "Do I need a building permit? Yes."[4]
Deck posts carry load, so read the state footing rule covered below before you order materials. For more on that, see the Wisconsin deck code guide.
Fence
Yes, a building permit applies here too.[5] The city states two conditions:
- Residential fences may not exceed six feet.
- A fence within three feet of a lot line with no record of a prior fence needs a survey by a registered land surveyor or engineer, unless a recordable affidavit is filed.
Confirm your lot line before you order panels.
Driveway and flatwork
Check with the city. The city's construction permit list shows no driveway, patio or flatwork application, so the answer for your lot comes from the office.[3]
Use the city's permit page. Ask whether the work touches the curb, sidewalk, boulevard or alley. If you need a pro, the Badger Flatwork directory covers concrete statewide.
Basement waterproofing
Check with the city here as well. No waterproofing permit application appears on the city's list.[3]
Ask whether excavation, footing work, plumbing or electrical for a sump pump would bring in separate permits. The Badger Basements directory lists waterproofing pros statewide.
| Project | Permit needed |
|---|---|
| Roof replacement | Yes |
| Deck | Yes |
| Fence | Yes |
| Driveway and flatwork | Check with the city |
| Basement waterproofing | Check with the city |
Finding the fee for a La Crosse permit
No fee for these five jobs appears on the city's pages. Check the city's fee schedule or ask the office for the current total in writing.[1]
The roof, deck and fence packets each point to Appendix C of the city code for fees.[2][4][5] Ask the office whether anything beyond the basic permit fee applies to your job.
Wisconsin fees are set by each municipality, so a figure from another city tells you nothing about La Crosse. For a side-by-side look, see the Wisconsin permits by city table.
The office to apply to and who inspects in La Crosse
The office is the City of La Crosse Building & Inspections. Its page is cityoflacrosse.org Building & Inspections, and the permit list lives on the city's Construction Related Permits page.[1][3]
Contact details and the application route are on those pages, so use them rather than a third-party summary.
Before work starts, ask the office to name every approval your job needs, not only the building permit. The city has the final word on what applies to your property.
Snow load and footing rules that sit on top of city permits
Two state rules sit on top of the city's permits. For the exact requirements, check with your local building inspector.
Roof snow load
La Crosse County is in Zone 2, which means a roof snow load of 30 psf. Zone 1 is 40 psf. The county is not on the zone line.[6]
The county-by-county list is on the snow load data page.
Footing depth
Wisconsin has one statewide footing rule, with no county table. Footings and foundations, including those for landings and stoops, go below the frost penetration level or at least 48 inches below adjacent grade, whichever is deeper.[7] Footings may not be placed on frozen material.
Depth
Minimum footing depth
Ground level
- 0 inchesAdjacent grade
- 48 inchesMinimum footing depth
Footings may bear directly on bedrock less than 48 inches down only if the rock is cleaned of earth, clay in crevices is removed to the required level, and water cannot collect along the foundation.[7]
A local inspector can ask for more than the state minimum. If your lot is sloped, ask the building inspector about footings there. Read more in the 48-inch footing rule guide.
Contractor certification needed to pull the permit
For a one- or two-family dwelling, the person who obtains the building permit must hold a Dwelling Contractor certification (or a Restricted certification), held through a certificate of financial responsibility.[8][9] That contractor must also hold, or employ, a Dwelling Contractor Qualifier.[10][11]
An owner who lives or will live in the dwelling and applies for a permit to do work on it is exempt.[9]
The credential is a permit-pulling credential, not a trade license. It does not say which trades may work, only who may obtain the building permit.[8]
Qualifier renewal takes 12 hours of department-approved continuing education.[10] To check a contractor, use the DSPS license lookup guide, and read the full Dwelling Contractor license page for the credential details.
The Wisconsin Department of Safety and Professional Services notes that most paint-disturbing renovation work in pre-1978 housing needs separate lead-safe certification through the Wisconsin Department of Health Services.[10]
La Crosse sits in our Driftless & West grouping, a navigation label and not an official boundary. Neighboring pages follow the same format, such as Oshkosh and Madison.
