SALT LAKE CITY HISTORIC LANDMARK COMMISSION

The Historic Landmark Commission (HLC) reviews all applications for landmark sites, demolition and new construction within locally-designated historic districts. They do not review interior work or exterior paint color, only exterior alterations. The majority of the projects presented to the HLC are either approved as submitted or with modifications.

Policy: When retrofitting a historic structure in Salt Lake City to improve its ability to withstand seismic events, any negative impacts upon historic features and building materials should be minimized. Many historic structures were built during times when there was less knowledge of seismic design and building codes were less restrictive. This makes them vulnerable to destruction in earthquakes. However, today there are methods of reducing the risk of earthquake damage. If carefully planned and executed, these retrofitting techniques can upgrade the safety of the home, while at the same time being sensitive to the historic fabric of the house.

Investigate the premises and identify its weak points and features that can be strengthened and reinforced. Execute the seismic retrofitting of a historic building so that it has the least impact on its architectural integrity. Building materials used in seismic retrofitting should be located on the interior and/or blended with other existing architectural features. Most projects that meet the Commission's standards receive administrative approval. Consult the Design Guidelines and Section 21A.34.020.G of the Salt Lake City Zoning Ordinance for the standards the Historic Landmark Commission uses in evaluating projects, or contact the Planning  staff for further information.
