Work out zoning compliance check instantly with clear inputs, formula shown and shareable results.
Zoning compliance is tested independently against each control. Floor area ratio caps total development intensity while ground coverage caps the footprint, and a scheme can satisfy one while breaching the other. Showing utilisation as a percentage reveals which control is binding and therefore where design effort should go.
Utilisation
Utilisation = proposed value / permitted value x 100, tested separately for each control
Preliminary estimate only. Full zoning compliance also covers setbacks, height, parking, ventilation and use, and must be confirmed with the planning authority.
Utilisation = proposed value / permitted value x 100, tested separately for each control. Zoning compliance is tested independently against each control.
Then the scheme must go taller on a smaller footprint to use the available floor area ratio, which usually means a more expensive structure and core.
This calculator takes 4 inputs: Floor area ratio proposed, Floor area ratio permitted, Ground coverage proposed, Ground coverage permitted. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
