Historic Resource Retention Incentive

The Historic Resource Retention Incentive is a way for owners of evaluated historic resources to increase the maximum density allowed on their property in exchange for legally protecting their historic building or site.
It is one of two Downtown District Heritage Incentives. The goal is to encourage land owners that are redeveloping heritage properties to preserve the buildings and features that have played a significant role in Calgary’s history.

How it works

In order to qualify for this incentive, you need to meet the following requirements:
  • Your property must be listed on The City’s Inventory of Evaluated Historic Resources.
  • Your property must be designated (zoned) as a CR20-C20/R20 District, which is described on pages 27-44 of Bylaw 22P2013.
  • You must be willing to legally protect the historic building or feature(s) by consenting to a Municipal Historic Resource Designation.
  • You must be willing to leave the historic building or feature(s) in its approved location on the site.
  • You must be willing to work with The City to evaluate the total cost of retaining the historic building or feature(s) so the right level of additional density can be calculated.
The additional density that you will be allowed to build is calculated using this formula:
Additional density (square metres) = Extra costs of preserving the historic resource
                                                                         $242 (if preserving just a building feature) OR
                                                                         $194 (if preserving an entire building)
For example, if it will cost $100,000 more to restore a heritage building than it would to simply build a new building on the site, you would qualify for approximately 515 square metres of additional density (100,000 divided by 194).

How to apply

You can apply for this incentive at the time that you submit a development permit application for your property.
City staff will then work with you to create an agreement outlining what type of rehabilitation you will do in exchange for what amount of added density. This agreement would also allow The City to legally protect your property as a Municipal Historic Resource.
The final decision on the development permit and agreement is made by the Calgary Planning Commission.
