Summary
Newport Beach lets small accessory structures, including sheds and mechanical equipment housings, sit inside the required side or rear yard setback if they stay six feet tall or less and no larger than 150 square feet per structure. Sheds cannot use this setback exception in a rear yard that backs onto an alley, per NBMC § 20.30.110(D)(2)(a).
Accessory structures, including housings for mechanical equipment, not more than six feet in height and totaling no more than one hundred fifty (150) square feet per structure, may be located within a required side or rear setback area other than a rear setback area abutting an alley.
Full Breakdown
110(D)(2)(a) of the Zoning Code carves out a specific encroachment allowance for small accessory buildings, including doghouses, garden sheds and housings built around pool equipment, air conditioning condensers or similar mechanical gear. A structure that is not more than six feet in height and totals no more than 150 square feet of footprint may sit inside a required side or rear setback area, letting homeowners keep a shed off the buildable pad without seeking a variance. The exception has one hard limit: it does not apply to a rear setback area that abuts an alley, where the Zoning Code keeps the area clear for vehicle access and utility service.
110. 040 instead of this exception. Homeowners planning a shed still need to pull a building permit from the Community Development Department for the structure itself; the setback provision only decides where on the lot it may sit, not whether a permit is required for construction.
Violations & Fines
An accessory structure that exceeds the six-foot height or 150-square-foot limit, or that encroaches into an alley-facing rear setback, is a Zoning Code violation enforceable citywide under NBMC § 1.04.010. The City can cite it as an infraction starting at $100 for a first offense and rising to $500 for repeat violations within a year, prosecute a continuing violation as a misdemeanor carrying up to a $1,000 fine and six months in jail, or pursue civil penalties of up to $1,000 per day until the structure is corrected.
