Frequently Asked Questions

If a property is individually designated or is within the boundaries of one of the Historic Districts shown on the Planning and Zoning Map, the property is subject to associated Historic Preservation (HP) requirements. Properties that are individually designated or are located within an historic district are subject to design standards to ensure the continued preservation of Aspen’s historic resources. 

All exterior work (and even some interior work) needs to be reviewed and approved by Historic Preservation staff before the work begins. Some examples of work that need review and approval are painting masonry, replacing windows, alterations to structural framing, replacing HVAC equipment, and any penetrations through historic material (some of this work may also require a building permit).  

If you are considering making any changes to a designated property or a property within one of Aspen’s historic districts, it’s a good idea to contact Historic Preservation staff before beginning. Historic Preservation staff are happy to conduct a site visit or schedule a chat with you to ensure your work complies with Historic Preservation standards. Email hp@aspen.gov to connect with Historic Preservation staff. 

A Transferable Development Right (TDR) allows certain properties to sever and convey, as a separate development right, undeveloped floor area to be developed on a different property within the City. To learn more about this program please reach out to hp@aspen.gov.
