Summary
Glen Cove's R-1A Two-Acre Residence District caps single-family construction at two and a half stories and 35 feet under City Code § 280-54.B(9). Citywide, § 280-45.Q measures that limit from existing grade to an imaginary plane parallel to finished grade, with peaked roofs measured to the ridge's midpoint.
Q. Height. ... (1) The maximum height of a structure shall be measured vertically from the existing grade to an imaginary plane located the allowed number of feet above and parallel to the finished grade (see diagram below illustrating application of this plane to a structure with a peaked roof). For peaked roofs, height shall be measured to the midpoint of the roof. No portion of a peaked roof below the midpoint shall extend above the imaginary plane. For flat and mansard roofs, height shall be measured to the top of the roof. No portion of a flat or mansard roof shall extend above the imaginary plane. (2) No structure shall exceed the maximum height in each district except as set forth in § 280-33. ... (9) Maximum height: 2 1/2 stories and in no event exceed 35 feet.

Full Breakdown
B(9), one line in the bulk table covering minimum lot area, frontage, and yard requirements for that district. Q, a rule that applies to every zoning district in the city, defines height as measured vertically from the existing grade to an imaginary plane parallel to the finished grade, set the allowed number of feet above it. For a peaked roof, the code measures to the ridge's midpoint, and no part of the roof below that midpoint may poke above the imaginary plane; for flat or mansard roofs, the measurement runs to the top of the roof itself, with no portion allowed to extend past the plane.
That same subsection cross-references § 280-33 for exceptions, meaning a structure can exceed the district maximum only where that separate section carves out an allowance, not by right. Because the height rule and its measuring method live in a citywide regulation rather than inside each district's own table, the same grade-to-plane methodology governs the R-1A district's 35-foot cap and the correspondingly numbered caps printed in the other residential and commercial district schedules elsewhere in Chapter 280.
Violations & Fines
Height violations are zoning violations under Chapter 280 and fall under the general penalty at § 280-74.A: a fine of $1,000 to $2,000 for a first offense, $2,000 to $3,500 for a second offense within five years, and $3,500 to $5,000 for a third, with up to 15 days imprisonment possible on any count. Each week an over-height structure remains is a separate violation, and the Building Department Director can pursue an injunction to compel compliance.
