Full Breakdown
040's residential development standards table sets primary structure maximum height at 35 feet across nine of the city's eleven residential zones: RA1, RA2, RD1, RD2, FR, R1, R2, R3 and RC. In the MF1 multifamily zone, footnote 8 caps multifamily dwelling structures at no more than three stories, still measured against the 35-foot baseline. In the MF2 zone, footnote 9 allows an exception: multifamily buildings with a minimum roof pitch of 5/12, or flat roofs carrying rooftop amenities, may be built with three stories up to 45 feet high.
Height itself is measured, per footnote 1, from the average of the highest and lowest finished grade of the structure to the highest point of the roof, excluding ancillary structures such as chimneys or antennas. 030, an ADU above a detached garage may reach 35 feet even in a zone where the base structure height would otherwise be lower for an accessory building.
Violations & Fines
A primary structure built above the applicable 35-foot or 45-foot cap without an approved exception is a Title 17 zoning violation, subject to the same code enforcement process as other development standards: the planning director conducts site inspections, issues certificates of compliance, and investigates and initiates proceedings to correct violations under EMMC 17.15.020.E. A builder relying on the MF2 45-foot exception must document the qualifying 5/12 minimum roof pitch or flat roof with rooftop amenities before construction, since that height is conditional rather than automatic.
