Do you need a building permit in the Town of Woodruff, Wisconsin?

Yes. The Town of Woodruff's ordinance says no one may build, add onto or alter a covered building without first getting a building permit from the Building Inspector1. The Town has adopted the Wisconsin Uniform Dwelling Code, so the rules cover new one- and two-family homes, additions, alterations and detached garages4. Restoration to a previous code-compliant condition, residing, reroofing, interior finishing, same-size window replacement, floor coverings and cabinetry are exempt1. Fees are set by Town Board resolution, and we could not confirm a current fee schedule, so ask the Town Clerk7. We also could not confirm a certificate-of-occupancy rule or an owner-builder exemption from the Town's permit; ask the Building Inspector before you plan to act as your own contractor.

Who issues building permits in Woodruff, and how do you reach them?

Inside the Town of Woodruff, the Town's own Building Inspector issues building permits, not Oneida County1. The Town's website lists the inspector's office on WI-47 in Woodruff, open Mondays, Wednesdays and Thursdays in the morning9. For questions about fees or town ordinances, the Town Clerk at town hall is the contact10. Zoning and septic stay with Oneida County Planning & Zoning in Rhinelander11.

Does Woodruff have zoning, and what does it mean for RVs, tiny homes and lot size?

Zoning inside the Town of Woodruff comes from Oneida County's Zoning and Shoreland Protection Ordinance, which names District 2 Single Family Residential, District 4 Residential and Farming and District 15 Rural Residential among its districts2. The county's zoning permit is required for most structures, including seasonal and permanent dwellings, garages and storage buildings11. Lot size depends on the district. In District 15, an off-water lot needs 5 acres with 300 feet of frontage and width8. In District 2, an unsewered back lot needs 50,000 sq ft, while a sewered back lot needs 10,000 sq ft12. District 4 uses the same back-lot areas of 50,000 and 10,000 sq ft13. Check the Official Zoning Map for the parcel's district2. Road setbacks are at least 20 feet from a documented right-of-way, and without one are measured 60 feet from the centerline of most public roads14. A tiny home is defined as a dwelling with a footprint of 400 square feet or less and follows the same district dimensions and setbacks15. The county adds that a town ordinance with greater restrictions continues to apply16.

How do septic permits work in the Town of Woodruff?

Septic permits for Woodruff addresses come from Oneida County, not the Town3. A sanitary permit is required to enlarge or install a sewage disposal system, and new or replacement permits need an application, plot plan, system information, management plan and soil evaluation report5. Oneida County's soils make this step matter: only about 0.3% of soils rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system17. We could not confirm whether the Town requires connection to public sewer; ask the Town Clerk. Private-well permit rules and off-grid sanitation inside the town also could not be confirmed, so ask Oneida County Planning & Zoning.

Can you live in an RV on your land in the Town of Woodruff?

Only in limited cases. An RV used as a dwelling must meet setbacks, minimum lot area and the dimensional rules for its zoning district6. One RV may be placed without a zoning permit for up to 2 years while a permitted permanent dwelling is under construction, and that exception is subject to the county's private onsite wastewater ordinance6. The county also requires a nonplumbing sanitary system permit when an RV is not connected to water or electric, and a private onsite wastewater sanitary permit when it is18. Tiny-home occupancy rules specific to Woodruff could not be confirmed.

Building a home in the Town of Woodruff: the steps, in order

  1. Find the parcel's zoning district on the county's Official Zoning Map and check lot size and setbacks2.
  2. Get a soil evaluation and apply for a sanitary permit from Oneida County Planning & Zoning5.
  3. Apply for the county zoning permit11.
  4. Apply for the Town building permit from the Building Inspector1.
  5. Build to the Wisconsin Uniform Dwelling Code, with the Town inspector checking the work4.
  6. If the driveway meets a state highway, a state driveway permit applies19.

What to check before you buy land in Woodruff

Ask the Town Clerk for the current building permit fee schedule and the Building Inspector about any owner-builder allowance7. Confirm the parcel's district and whether it is on a lake or stream, since shoreland grading within 200 feet of the shoreland needs a county permit11. Oneida County's effective property tax rate is about 0.9%, with a median bill of $2,146 a year2021. For land outside the town, see the Oneida County page, because county rules for unincorporated land differ from the Town's.

Watch-outs

  • The Town building permit and the county zoning and sanitary permits are separate applications from separate offices, so getting one does not cover the others13.
  • We could not confirm tiny-home occupancy, accessory dwellings, driveway permit rules inside the town, or private-well permits; ask the Building Inspector or Oneida County Planning & Zoning before you buy22.
