Answers from the rulebook for Town of Pine Grove

Town of Pine Grove’s own rules

  • Building permitRequired

    New dwellings inside Pine Grove town; the town's UDC building inspector (Benjamin Grimm, (715) 305-8814 per county contact sheet) issues the permit

    • Permit may also be required for other improvements.
    • A zoning permit (county) is separate and is not a building permit.
    • Construction may proceed after the permit is issued.
    “a uniform dwelling code (udc) building permit is required for all new dwellings and may be required for other improvements. these permits are issued by the town.”

Rules another office applies inside Town of Pine Grove

Town of Pine Grove does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • Local zoningVaries (with conditions)

    Land inside Pine Grove town that lies within shoreland or floodplain areas: Portage County zoning permit applies there. Not a finding that Pine Grove has its own zoning ordinance.

    • The county procedures document says the county zoning permit applies to Pine Grove residents only where the project is within shoreland or floodplain areas.
    • The same document lists the towns where a county zoning permit is needed for any project (Alban, Almond, Amherst, Belmont, Buena Vista, Carson, Dewey, Eau Pleine, Hull, Lanark, Linwood, New Hope, Plover, Sharon, Stockton). Pine Grove is not on that list; this omission is an inference, not an explicit statement.
    • When a county zoning permit is required in these areas it covers construction of new homes, additions that increase floor area, placement of campers in agricultural, conservancy and/or rural limited zoning districts, accessory buildings of 100 square feet or more, and soil disturbance greater than 1,000 square feet including driveways.
    • A separate stormwater review may be required case by case.

    accessory building size requiring county zoning permit: >= 100 square feet (accessory building under 100 square feet is exempt if it meets setbacks, yard and open space requirements) · soil disturbance requiring county zoning permit: > 1000 square feet (includes driveways)

    “residents of the towns of grant and pine grove will also need a portage county zoning permit if their project is located within shoreland or floodplain areas.”
