Tower regulations

Tower regulations govern building portions rising above a specified level in the highest-density districts. Instead of capping height with a plane or a flat maximum, they discipline the tower by lot coverage: the floor plates must stay within a limited share of the zoning lot, and height may then continue. Slenderness, not shortness, is the price of the sky.

Tower-on-a-base variants add a required contextual base — a street wall within a prescribed band — so avenue frontages stay continuous beneath the shaft. Towers are not unlimited: the floor-area budget still caps the total, and district or special-district rules can add caps and conditions. The slender residential tower is this regime meeting a small lot and a large, often assembled, floor-area budget.
