Full Breakdown
Table 2-2 in the Residential Zoning Districts chapter sets the minimum yard setbacks for each single-unit district: R-A, R-1, R-1-6,000, R-1-7,200 and R-1-10,000. Front setbacks run 20 feet in R-A, R-1, R-1-6,000 and R-1-7,200, dropping to 15 feet in the larger-lot R-1-10,000 district. Interior side setbacks on lots 40 feet wide or narrower are 5 feet in R-A, 3 feet in R-1, 6 feet in R-1-6,000, 5 feet in R-1-7,200 and 10 feet in R-1-10,000; lots wider than 40 feet add a foot to the R-1 figure.
Rear setbacks range from a tight 6 feet in R-1-6,000 up to 25 feet in the estate-lot R-A district, with R-1 at 10 feet, R-1-7,200 at 20 feet and R-1-10,000 at 10 feet. Where the City has adopted a setback map for a block, that map controls instead of the table, and side or rear areas shown on a setback map are treated as front setback areas for regulating accessory structures. 110, which also lists the specific encroachments the Community Development Department allows into these areas, such as eaves projecting up to 30 inches or freestanding barbecues along the side and rear lines.
Alley-facing lots as narrow as 10 to 15 feet trigger a reduced first-floor alley setback under the same table. Any project that cannot meet the table's minimums needs a variance or modification permit reviewed by the Zoning Administrator before the Community Development Department issues a building permit; disputes over an adopted setback map are resolved by the Director's office rather than by ordinance amendment.
Violations & Fines
Building or expanding a structure inside a required setback without an approved permit is a code violation citywide under NBMC § 1.04.010. The City may cite it as an infraction, with fines of $100 for a first offense, $200 for a second within a year and $500 for each later repeat, or prosecute a continuing violation as a misdemeanor punishable by up to $1,000 and six months in jail; the City Attorney can also seek civil penalties of up to $1,000 per day.
