Calculates floor-area ratio and lot coverage and compares use, height, parking and geometr
Calculates floor-area ratio and lot coverage and compares use, height, parking and geometry with an explicit caller-supplied rule set. It does not retrieve or interpret current law, resolve overlays or variances, establish entitlements or provide legal advice; an official planning authority must verify any real project.
