Summary
Lynn's 2025 Zoning Ordinance caps building height by district, from 35 feet in the R1 and R2 single-family districts up to 240 feet in the RT and M2 districts, measured from the average street-frontage elevation to the roof under Section 4.
g. The building height shall be measured from the average elevation of the street frontage to the highest point of the roof for flat roofs, to the deck line for mansard roofs, and to the mean height between eaves and ridge for gable, hip and gambrel roofs. Fences and walls shall be measured from the Finished grade vertically to the highest point. h. Rooftop building elements may exceed the maximum height limit defined herein by up to 15 feet provided that they occupy in the aggregate less than 20 percent of the area of the roof on which they are located and are located and designed as to minimize visibility from the street to the extent practicable. Examples include elevator or stairway enclosures, spires, towers, chimneys, broadcasting and television antennae, ventilators, roof-mounted solar energy systems, and other appurtenances or ornamental features usually located above the roof, which features are in no way used or suitable for use for occupancy or storage purposes.

Full Breakdown
1's Table of Dimensional Requirements sets a maximum building height for every zoning district: 35 feet in R1 and R2, 40 feet in R3, 75 feet in R4, 35 feet in B1, 45 feet in B2, 120 feet in the BC business-core district, 55 feet in M1, 100 feet in M2, 70 feet in MV, 120 feet in RD, and 240 feet in the RT district, with 60 feet in both IL and IH. Several districts also allow taller buildings by special permit from the City Council, up to 75 feet in R3, 120 feet in R4, and as high as 240 feet in M2 or RD.
g fixes how height is measured: from the average elevation of the street frontage to the highest point of the roof for flat roofs, to the deck line for mansard roofs, and to the mean height between eaves and ridge for gable, hip and gambrel roofs, while fences and walls are measured from finished grade to their highest point. h then carves out a rooftop allowance: elevator or stairway enclosures, spires, chimneys, antennae, ventilators and roof-mounted solar equipment may rise up to 15 feet above the district's height cap, provided they cover less than 20% of the roof area in the aggregate and are sited to minimize street visibility.
i, must sit at least 10 feet from any lot line, a siting rule that works alongside the height table rather than the projection allowance.
Violations & Fines
Building above the district height cap, or exceeding the 15-foot rooftop-element allowance on more than 20% of the roof, is a Zoning Ordinance violation under Section 11 enforced by the Building Commissioner. It's a misdemeanor with a $300 fine per violation plus costs and legal fees, each day counted separately, though the Commissioner may pursue a noncriminal fine under G.L. c.40, Section 21D instead.
