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.

Frequently Asked Questions

What is the minimum front setback in Newport Beach's R-1 zone?
Newport Beach requires a 20-foot front setback in the R-1 zoning district under Table 2-2 of NBMC § 20.18.030. That figure also applies to the R-A, R-1-6,000 and R-1-7,200 districts; only the larger-lot R-1-10,000 district drops to a 15-foot front setback. A local setback map can supersede the table where the City has adopted one for that block.
How narrow can a side setback be in Newport Beach?
On R-1 lots 40 feet wide or less, the interior side setback drops to just 3 feet, the narrowest figure in Table 2-2. R-1-6,000 and R-1-7,200 require 5 to 6 feet, and R-1-10,000 requires 10 feet. Lots wider than 40 feet add one additional foot to the R-1 side setback.
Can a setback map override the zoning table in Newport Beach?
Yes. NBMC § 20.18.030 states the table figures apply unless different requirements are identified on the City's setback maps, in which case the maps control. Side and rear areas shown on a setback map also count as front setback areas when the City regulates where an accessory structure like a shed can go.
