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.

Windows

Policy: The character-defining features of historic windows and their distinct arrangement should be preserved. In addition, new windows should be in character with the historic building. This is especially important on primary facades. Preserving historic windows is always preferable to replacement. As a rule of thumb, if 50% of the existing window can be repaired, then the window should not be replaced. Consider exterior or interior storm windows as an alternative to insulated glass. A well-built storm window system with single paned windows has been shown to be as energy efficient as replacement multi-paned windows. If windows must be replaced, the new windows should match the historic windows to the greatest extent possible. New windows should fit into the existing openings, match the original window type, and preserve wood casing around the sash. Substitute materials such as metal and vinyl-clad wood and vinyl windows will be considered on secondary facades of the house. The new window should match the original window in design and sash profile.

Window replacement projects are most often approved under administrative review. Staff refers some proposals for substitute materials to the Architectural Subcommittee or Historic Landmark Commission for review. 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 window projects, or contact the HLC staff for further information.
