Full Breakdown
House A is Hartford's large, wide residential building on an oversized lot, and Section 4.14.2 sets its height rules in three districts: MX-1, MX-2 and N-1. Part B of the table fixes three line items: minimum overall height, maximum overall height, and the floor-to-floor range for every story.
Every House A building must reach at least 2 stories in all three districts. Section 4.18.2(A) adds that the minimum overall height is located within the build-to zone, and that stories above the required minimum can be required to step back from the facade.
The ceiling is 3 stories in MX-1 and 3.5 stories in MX-2 and N-1. Section 4.18.2(B) defines maximum overall height as the sum of a building's maximum total number of stories. A half story counts in only two forms: one located completely within the roof structure with street-facing windows, or a visible basement exposed a maximum of one half story above grade. A building with both counts the two half stories as one full story.
Each story is measured floor to floor, from the floor of a story to the floor of the story above, and must fall between 9 feet and 14 feet in every district. Those floor-height requirements apply only to street-facing facades. On a single-story building or the uppermost story of a taller one, the measurement runs to the tallest point of the ceiling, and one foot can be deducted from the required minimum for top stories.
Rooftop items sit outside the cap. Accessory rooftop appurtenances allowed under Section 4.20, building mechanicals, skylights, chimneys, smokestacks, permitted communication antennas and water tanks can rise above the maximum, but never more than 15 feet over the district limit, never covering more than 10 percent of the roof area (accessory energy generation is exempt from that area cap), and never for a use other than one incidental to the principal use. Row 26 of the table also lists pitched and tower as the permitted roof types for House A in all three districts.
Violations & Fines
A House A proposal fails Section 4.14.2.B if it rises above 3 stories in MX-1 or above 3.5 stories in MX-2 or N-1, stops short of 2 stories, or lays out a street-facing story with a floor-to-floor height under 9 feet or over 14 feet. Rooftop equipment that climbs more than 15 feet over the district limit, or covers more than 10 percent of the roof, also breaks Section 4.18.2(B)(4). The sections read here state the standards and do not print a fine.
