City and County of Denver - Solar Panel Permitting

The City and County of Denver was designated the first "Solar Friendly Community" in the nation based upon its streamlined permitting process.

Denver provides same-day permit review for most solar panel projects. Electrical, Plumbing, and Zoning Permits* are required for photovoltaic (PV) systems installed in the city of Denver, although more complex engineering projects may still be required to go through the Plan Review process.

Permitting Process

Zoning Permits are required if the panels will be installed at an angle to the slope of the roof and are not "flush mounted," or if a generator or energy storage system is

Local Option - Commercial PACE Financing

Note:  In 2010, the Federal Housing Finance Agency (FHFA), which has authority over mortgage underwriters Fannie Mae and Freddie Mac, directed these enterprises against purchasing mortgages of homes with a PACE lien due to its senior status above a mortgage. Most residential PACE activity subsided following this directive; however, some residential PACE programs are now operating with loan loss reserve funds, appropriate disclosures, or other protections meant to address FHFA's concerns. Commercial PACE programs were not directly affected by FHFA’s actions, as Fannie Mae and Freddie Mac do not underwrite commercial mortgages.
