Full Breakdown
Table 4.1-1 of the Unified Development Code fixes minimum yard setbacks for each residential zoning district in Columbia, Missouri, Boone County. R-1 and R-2 lots require a 25-foot front yard, a 6-foot side yard, and a rear yard equal to the lesser of 30 percent of lot depth or 25 feet (25 percent of lot depth or 25 feet in R-2). R-MF lots need only a 10-foot front yard and 6-foot side yard (10 feet for 3+ unit structures), while R-MH manufactured-home lots use a 20-foot front yard and 10-foot side and rear yards. Columbia's community development department enforces these standards through the building permit process.
