Summary

St. Louis County can designate a building, site, structure, monument, or neighborhood as a Landmark and Preservation Area (LPA) under Section 1003.191 when it holds historic, architectural, cultural, or archeological significance. Once the County Council approves an LPA by ordinance, Section 1007.050 makes it unlawful to demolish or move any building or structure there without a permit reviewed by the Historic Building Commission.

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

1. Purpose and intent. The purpose of this section is to promote the general welfare, heritage, education and economic benefit of St. Louis County, through the preservation, protection and regulation of buildings, sites, structures, monuments, and neighborhoods of historic, architectural, cultural or archeological significance. It is further the intent of this procedure to encourage the adaptation of these buildings, sites, structures, etc. for current use. 2. In any zoning district, except "PS" Park and Scenic District, a single parcel or geographic area may be designated as a landmark and preservation area thereby encouraging the preservation, enhancement, rehabilitation and perpetuation of the landmark building, structure or area. The Planning Commission may recommend and the County Council, by ordinance, may approve designation for a specific parcel or area provided the area is characterized by one or more of the following criteria: (1) has significant character, interest or value as part of the development, heritage or cultural characteristics of the County of St. Louis, State of Missouri, or the United States.

Full Breakdown

191 lets the Planning Commission recommend, and the County Council approve by ordinance, LPA designation for a specific parcel or area characterized by significant heritage or cultural value, association with a significant historic event, work of an influential designer, distinctive architectural craftsmanship, or status as an established visual landmark of a neighborhood. 030 as a nine-member body within the Department of Parks and Recreation, reviews and comments on every designation petition before the Planning Commission makes its recommendation to the County Council; the Planning Commission construes the Commission's silence as acceptance.

Approval must be accompanied by conditions written into the designating ordinance covering permitted uses and maximum floor area, preservation and design standards for new construction and repair, height limits, exterior facade review by the Historic Buildings Commission, minimum yard requirements, off-street parking and loading, sign regulations, and any deed restrictions. Designation also unlocks additional uses beyond what the underlying zoning district allows, such as offices, limited retail and studio space, and affiliated dwelling units for an owner, manager, or employee, subject to a 4,000-square-foot cap on any manufacturing use.

050, once an area is designated, no one may demolish or move a building or structure there without first obtaining a permit; the Historic Building Commission reviews every application and determines whether the proposed demolition or move is detrimental to preserving the buildings, sites, and structures the designation protects.

Violations & Fines

A petitioner denied LPA designation, or a nearby property owner protesting an approval, may appeal to the County Council under Section 1003.193 within ten days of the Planning Commission's report, with a $200 filing fee for a petitioner's appeal or signatures from owners of 25 percent of nearby land area for a protest. Demolishing or moving a designated structure without the Historic Building Commission's permit is unlawful under Section 1007.050 and is enforced through the County's standard zoning violation powers, including stop-work orders and County Counselor referral for prosecution.

Frequently Asked Questions

What qualifies a site for Landmark and Preservation Area designation?
Section 1003.191 allows designation of a parcel or area with significant character, interest, or value tied to the County's development, heritage, or cultural characteristics, the site of a significant historic event, the work of an influential designer, distinctive architectural craftsmanship, or an established visual landmark of a neighborhood, subject to County Council approval by ordinance.
Can I demolish a building inside a designated LPA?
No. Section 1007.050 makes it unlawful to demolish or move any building or structure in a designated landmark and preservation area without a permit, and the Historic Building Commission reviews every application to decide whether the demolition or move would be detrimental to the area's preservation purpose.
Who reviews an LPA designation before the County Council votes?
The Historic Buildings Commission, a nine-member body under the Department of Parks and Recreation, comments on every petition, and the Planning Commission then makes a recommendation addressing those comments, planning consistency, and compatibility with adjoining uses before the County Council acts by ordinance.
How do I appeal a denied or approved LPA petition?
Section 1003.193 lets a denied petitioner appeal to the County Council within ten days of the Planning Commission's report for a $200 filing fee, while owners of 25 percent of nearby property area may file a protest against an approval within the same ten-day window.
