Denver Deck Permit Guide

Denver publishes specific deck thresholds for zoning and building permits, making deck height one of the first details to verify.

Permit takeaway

Denver says uncovered decks more than 12 inches above ground require a zoning permit; decks 30 inches or more above ground also require a building permit.

Zoning and placement

Covered patios, porches, pergolas, and carports generally need both zoning and building permits.

Building and trade review

Electrical, plumbing, mechanical work, drainage, floodplain, sewer, forestry, and demolition issues can add permits or review.

Call before applying when

Call before applying if the deck is covered, high above grade, near a sewer line, in a floodplain, connected to a driveway change, or replacing an old structure.
