Answers from the rulebook for Gem Township

Rules another office applies inside Gem Township

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

  • Building permitRequired

    Structures in unincorporated Brown County under Title 4, which would include Gem township unless it falls in a joint-jurisdiction area. A permit is issued by the county zoning administrator.

    • Permit is required where improvement market value exceeds $2,000, or for any structure regardless of cost if additional land or area is required for it to be sited on.
    • No permit may be issued except in conformity with Title 4.
    • Fees are set annually by the county commissioners and posted in the zoning office.
    • The ordinance does not name Gem township.

    improvement value threshold: > 2000 USD (any structure needing additional land or area to be sited on requires a permit regardless of cost)

    “building permits are required in the following instances: 1. for any improvements on or to any structure/building in which the market value (net worth) of the improvement exceeds $2,000; or 2. for any structure or building, regardless of cost, if additional land or area is required for it to be sited on.”
