  • Ordinance has been amended several times since 2013 (amendments listed on the county page through May 17, 2026 rooftop solar); the county page says the current text should be confirmed with Town Hall.

  “planning & land management staff helps administer the mountain lake park zoning ordinance and works with the town to provide final review and approval of all required zoning permits.”

  • Per-district numbers are in the Table of Dimensional Requirements (ordinance section 501). The extracted text of that table is column-scrambled, so no numeric lot sizes are recorded here; see followups.
