Thornton zoning code requires minimum setback distances from property lines for all structures. Setbacks vary by zoning district and structure type.
Thornton zoning ordinance establishes minimum setback distances that structures must maintain from property lines. Typical residential setbacks include 20 to 25 feet front, 5 to 10 feet side, and 15 to 20 feet rear. Corner lots may have increased side setbacks along the street. Accessory structures like sheds and garages often have reduced rear setbacks of 3 to 5 feet. Setbacks vary by zoning district (R-1, R-2, commercial, etc.). Variances require a hearing before the zoning board. Encroachments like eaves and decks may have exceptions.
