Summary

Sangamon County's Historic Preservation Commission can designate landmarks and preservation districts for cultural, architectural or historic significance, requiring a certificate of appropriateness before alteration or demolition.

City-specific rules exist: Springfield has its own historic-cultural monuments rules that differ from Sangamon County's county-level regulations. If you live in Springfield, check the city-specific page instead.

The preservation commission or any person may propose landmarks or preservation districts for designation by the county board by filing a nomination for any property or properties and structures located in an unincorporated area within the geographical boundaries of Sangamon County and those municipalities as provided for by statute.

Nomination forms shall be filed with the preservation commission. Such forms shall be provided by the commission and, when submitted, shall include or be accompanied by all of the following information:

The name and address, as shown on the tax assessor's rolls of the owner of record of the nominated property; The Permanent Index Number (PIN), legal description, and common street address of the property proposed for designation; A map delineating the boundaries and location of the property proposed for designation; Photographs of the property showing all sides of the property; A written statement describing the property and setting forth reasons in support of the proposed designation; In nominating an area for designation as a preservation district, a list enumerating all properties and improvements previously designated, or currently pending designation, as a landmark by this commission or listed on any state or federal registers of historic places. There shall be no fee for submitting or resubmitting a nomination form to the commission for designation of an historic landmark or preservation district.

Full Breakdown

Under Sangamon County Code § 15.06.080, the preservation commission or any person may nominate landmarks or preservation districts covering property in the unincorporated county and municipalities as provided by statute. The commission reviews nominations against criteria in § 15.06.090, and the county board designates by ordinance. Once designated, § 15.06.230 bars significant exterior alteration, construction, demolition or removal without a certificate of appropriateness from the commission, and § 15.06.190 allows marking the site with a plaque.

Violations & Fines

Violating the preservation ordinance, including altering a designated landmark without a certificate of appropriateness, carries a fine of $25 to $500 per offense, with each day of continued violation a separate offense under § 15.06.300.
