Full Breakdown
The base rule is § 108-5.10(A) of the Monroe Township Code: no structure can extend higher than the limit provided in each zone for building height. The figure itself is not printed in § 108-5.10. It sits in the zone district regulations and in the Schedule of Area, Yard and Building Requirements that § 108-6.4 attaches to Chapter 108, so the first step is identifying which zone the lot is in. The definition in § 108-2.3 measures building height as the vertical distance from the average elevation of the proposed finished grade at the front of the building to the highest point of the roof, and it counts chimneys, spires, water towers, elevator penthouses, tanks and similar projections other than signs.
Section 108-5.10 then carves out exceptions. Subsection (B) says the height limitations do not apply to spires, belfries, cupolas or domes not used for human occupancy, or to parapets, walls or cornices extending not more than four feet above the building height limit. Subsection (C) separately says the limits do apply to chimneys, spires, water towers, elevator penthouses, tanks, ventilators, skylights, stair towers and similar projections, but those can exceed the limit by not more than 15 feet, and skylights, heating and air-conditioning equipment and ventilators by no more than 10 feet. Such features cannot exceed, in total coverage, 10% of the total roof area. Subsection (D) lets freestanding, noncommercial radio and television antennas and flagpoles exceed the limits by not more than 15 feet. Because (B) and (C) both name spires, ask the Zoning Officer which one applies to a given project.
Particular districts print their own numbers. The Planned Retirement Community District under § 108-6.14 says no buildings shall exceed a height of two stories or 35 feet, with water tanks, towers and church spires permitted up to 55 feet, and § 108-5.6(B) holds accessory buildings in residential zones to the lesser of 16 feet or the height of the principal building.
Violations & Fines
Violations of Chapter 108 are punished under § 108-14.4. The owner, contractor or anyone who takes part in the violation faces a fine of not more than $1,000, imprisonment for a term not exceeding 90 days, or both, and each day the violation continues counts separately. Under § 108-14.1 the Zoning Officer reviews plans and premises, and no development permit is granted for construction that would violate the chapter.
