Full Breakdown
Chapter 30, Sec. A defines building height as the vertical distance between the average grade plane and the highest point of the roof. Several features are excluded from that measurement: cornices projecting no more than 5 feet above the roofline, chimneys and elevator enclosures up to 15 feet above the roofline, rooftop tank enclosures up to 20 feet that cover no more than 10% of the roof area, solar panels extending no more than 1 foot above a sloped ridge or 4 feet above a flat roof's parapet, and ornamental towers, spires and domes.
Sec. 2 flatly bars any habitable space above the maximum allowed height. The Sec. 5 stories as of right, with the City Council able to grant a special permit for up to 3 stories. Sec. C defines a half story as one under a sloped roof where less than two-thirds of the floor area has a ceiling of 7 feet or more, and Sec. D treats any story that is two-thirds or more below the average grade plane as a basement rather than a counted story.
The Commissioner of Inspectional Services applies these limits at building permit review under Sec. 1, and the Sec. 1 table was most recently amended by Ordinance No. C-67 on October 20, 2025.
Violations & Fines
Constructing above the 36-foot sloped-roof or 30-foot flat-roof maximum, or adding a third story without a special permit, violates Chapter 30. Sec. 7.9.2 fines the property owner up to $300 for each day the violation continues, and the Commissioner of Inspectional Services can refuse a building permit for work that exceeds the district's height table. Appeals of enforcement decisions go to the Zoning Board of Appeals within 30 days.
