Harrodsburg’s own rules

• Local zoningPresent (with conditions)

  Land inside Harrodsburg city limits: the Harrodsburg Zoning Ordinance, 2026 edition (listed as NHZO 3-5-26) on the Mercer County planning and zoning ordinances page.

  • Only the county page's listing of this ordinance was verified. The ordinance PDF returned HTTP 404 to the research tool, so its text, dimensional standards and effective date were not read.
  • Unincorporated Mercer County land is governed by the Mercer County Zoning Ordinance 2026 (MCZO 2026-01) listed on the same page, not by this ordinance.

Rules another office applies inside Harrodsburg

Harrodsburg 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

  • Permit issued from the planning and zoning office at city hall after plan review; permit must be posted on the property.
  • Rule-maker is Mercer County's building inspector office, not a city-enacted rule; the page states it applies to projects within the city limits.

  Permitted construction inside Harrodsburg city limits handled by the Mercer County building inspector.

  • Plumbing inspections are performed on Tuesdays only and separate fees apply.
  • Septic inspection appears in the final sequence only where septic applies; inside the city, sewer connection is the documented alternative.
