Zoning, building permits and septic rules in Union Grove Township, Illinois

Rules another office applies inside Union Grove Township

Union Grove 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

  Land inside Union Grove township outside any city or village limits, where Whiteside County (not the township) issues building permits

  • The county page covers unincorporated areas of Whiteside County; the township's incorporated-area status was not verified, so land inside any city or village limits is governed by that municipality instead.
  • The page does not state the exact construction types exempted, so exemptions are not established here.
  • Union Grove township itself has not been shown to adopt its own building permit ordinance in the sources opened.

  “building and demolition permits are required for all structures built, moved, altered, demolished, destroyed by natural forces in unincorporated areas of whiteside county.”

• Who permits septicCounty (with conditions)

  Private residential on-site sewage disposal systems on land inside Union Grove township, as administered by the Whiteside County Health Department

  • The permit form is issued by the Whiteside County Health Department; the form does not name Union Grove township, so the township's inclusion in the department's service area is inferred, not quoted.
  • Illinois state rules may also apply to private sewage systems; not analyzed here.

  “permit application to construct a private residential on-site sewage disposal system for homeowner whiteside county health department, 1300 w 2nd street, rock falls, il 61071”

• Permit feesPublished (with conditions)

  Homeowner installation permit for a private residential septic system in Union Grove township (Whiteside County Health Department fee)

  • Fee shown on the 2025 form; a later fee schedule may exist and was not checked.
  • The form marks the fee with an asterisk; the footnote text was not captured.
  • Building permit fees from the county Building & Zoning office were not located.

  homeowner installation permit fee: 460 USD (tank only: $360.00 per the same form)

  “homeowner installation permit fee*: $460.00 tank only: $360.00”
