Flagstaff, AZ Building Setbacks & Zoning: Structure Height Limits (2026)

The Flagstaff Zoning Code sets maximum building height by residential zone in Table 10-40.30.030.C, part of Section 10-40.30.030, Residential Zones. The Rural Residential (RR), Estate Residential (ER), Single-Family Residential (R1), Single-Family Residential Neighborhood (R1N) and Medium Density Residential (MR) zones share a 35-foot maximum. The Manufactured Housing (MH) zone caps buildings at 30 feet. The High Density Residential (HR) zone allows 60 feet outright, and End Note 4 to the table lets that ceiling be exceeded only with an approved conditional use permit, so an HR project over 60 feet needs Planning Commission or Council-level review rather than an over-the-counter permit.

Three end notes let a homeowner add height beyond the base number in every zone. End Note 11 grants an extra five feet to primary structures, not accessory structures, that carry a roof pitch of 6:12 or steeper, rewarding the snow-shedding roofs the City's own design guidance recommends for Flagstaff's snow loads. End Note 12 allows elevator and stairwell bulkheads an extra 15 feet above the zone maximum if they are architecturally integrated with the building, and the Director can approve even more when an elevator, stairwell or Building or Fire Code requirement needs it. End Note 13 gives steeples, solar collectors, towers and other unoccupied architectural features additional height equal to 20 percent of the zone's maximum, capped at 20 percent of the total roof area.

Community Development's Zoning Administrator checks height at building permit application; a plan showing a structure over the table maximum, without a qualifying bonus or an HR conditional use permit, is not approved until it is revised.
