Full Breakdown
Quincy's Table of Dimensional Requirements sets no lot-coverage percentage; instead Section 4.2.4 caps building bulk as a floor area ratio: gross floor area divided by lot area. Residence A has no FAR limit at all (yard, height, and story caps govern instead); Residence B ranges 0.4 to 0.5 depending on unit count; Residence C is capped at 1.0; and caps rise through the business and industrial districts to a high of 3.5 in Business C2.
Violations & Fines
Exceeding the district's floor area ratio is a zoning violation: $300 per offense, with each day of noncompliance a separate offense, enforced by the Director of Inspectional Services.
