Setback Requirements
Setback requirements are zoning regulations specifying minimum distances that buildings and structures must be positioned from property lines, streets, and other structures.
Setbacks create minimum distances between your house and property lines, preventing overcrowding and maintaining neighborhood character. Denver's zoning codes specify front, side, and rear setbacks varying by zone district. Typical single-family zones require 15-20 feet front setback, 5 feet side setbacks, and 15 feet rear setback—but these vary significantly. Setbacks apply to houses, garages, decks, and other structures. Additions and new structures must comply with current setback requirements even if existing structures are non-conforming.
Why They Matter for Your Project
Setbacks determine where you can build additions and accessory structures. Violating setbacks creates serious problems: building departments can require removal, and encroachments onto neighbors' property create legal liability. Before planning additions, verify your setbacks with a survey or Denver's Accela system. Consider: Can you expand toward the side or back? Will a second story addition comply? Where can you locate a detached garage or shed? Older homes may have legal non-conforming setbacks, but can't be expanded further into setback areas.
Common Setback Rules in Denver
- Front setback: 15-20 feet typical for single-family zones
- Side setback: 5 feet typical, may be reduced for certain accessory structures
- Rear setback: 15 feet typical for primary structures
- Corner lots: Front setbacks apply to both street-facing sides
- Accessory buildings: Relaxed setbacks (sometimes 3 feet) for detached garages and sheds
- Obtain zoning letter from Denver confirming your property's requirements
