Frequently Asked Questions

The Planning and Zoning map is maintained by the City’s GIS department. It can provide a wide variety of information related to development, such as zone district, parcel information, and environmentally sensitive areas (ESA). To navigate, open the map and use your mouse to zoom into the area of interest. Some information is presented visually, such as the zone district overlay and the orange historic designation boundaries. Other information can be found by clicking on the parcel. You can search for an address by clicking on the magnifying glass in the top right corner and then zooming in to select the parcel. On the right-hand side is a legend which helps identify what information is being expressed. Next to where it says legend, you can find the different map layers; this allows you to add or remove layers from view, such as the Mountain View Plane layer. To do this, go to the right side of the layer you're interested in and click the eye icon.  

The Planning and Zoning map shows City limits as an orange dashed line. If the property is contained within the orange dashed line, it is within the City of Aspen. 

The Zone District Map is incorporated in the Planning and Zoning map on the Community Development website. Find the property by selecting the magnifying glass in the top right corner and entering the address. Select the property to generate a pop-up. Using the arrows in the pop-up, find the zoning tab where it will say the parcel’s zone district. Alternatively, the color of the parcel corresponds to the Zoning Legend on the right-hand side. 

A “Parcels” pop-up will be generated when you select the parcel you’re interested in on the Planning and Zoning map. The “Parcel Number” is the same as the parcel ID. You can also find out the parcel ID by searching the property on the Pitkin County Assessor’s site.  

Chapter 26.710 of the Land Use Code contains information about the zone districts in the City of Aspen. 

It depends on the zone district. Refer to 26.700, Zone Districts, in the Land Use code and refer to the dimensional requirements for the zone of interest. Refer to 26.575.020 for additional information.

26.700, Zone Districts, in the Land Use Code outlines the permitted uses based on the zone district of the property. If you are considering a conditional use, that would require additional review, which can be coordinated by emailing  planneroftheday@gmail.com. If you are unsure if the proposed use falls under the allowed use categories, please refer to 26.104.110 - Use Categories. 

If a property is associated with a planned development, it would have a “PD” overlay on the Planning and Zoning map. To find out more information about a planned development, refer to the Pitkin County Clerk Website or reach out to planneroftheday@gmail.com.
