Historic Preservation Tax Credits

Historic preservation tax credits lower your state property tax bill.  

Historic homeowners can earn credits for

  • Upgrades to your house’s electrical, plumbing, heating and air conditioning systems.  

  • Exterior rehabilitation work such as foundation repairs, re-roofing, brick masonry repointing, repairs of historic woodwork, and rehabilitation of historic windows can also qualify.   

The Basics

  • Complete an application form, and submit to Denver Landmark Preservation.  You will need to include contractor bids with your application.

  • Only projects consistent with historic preservation guidelines and standards qualify for the tax credits.

  • For historic preservation work items, such as restoration of historic windows or brick repointing, hire a contractor with experience working on historic buildings.

  • Apply in advance of beginning work, ideally at least 30 days prior to beginning work.

  • Keep your project simple, ideally to include no more than a few items.  Keep your historic preservation tax credit project separate from other home improvement projects.   

  • A tax credit project can include multiple work items, as long as the costs add up to at least $5,000.    

  • The eligible credit amounts to 20% of the project costs.  As an example, a project to replace a deteriorated roof, install a new heating system and repair historic windows costs $30,000, earning the property owner a $6,000 state tax credit.  An owner can apply this credit to taxes owed for up to 10 years.

  • For more information see the State Historic Preservation Income Tax Credits page on the Denver Landmark Preservation website, and review the customer guide.

  • Contact Denver Landmark Preservation staff for advice prior to applying.  Receive an informal go-ahead on your project from city staff prior to submitting a formal application, since there is an upfront application fee.
