Denver has updated its zoning code to streamline the approval process, relax design standards and open up more space for businesses ranging from bars and restaurants to salons and tattoo parlors to set up outdoor patios. The updated regulations, approved via a unanimous City Council vote Monday night, build off temporary, pandemic-era changes the city made to its rules to provide flexibility to small businesses struggling under public health occupancy restrictions. They are the first step in a broader effort city officials are calling the Outdoor Places Program.
