Work out visitor parking requirement instantly with clear inputs, formula shown and shareable results.
Visitor parking is normally specified as a percentage of dwelling units, commonly five to ten percent, and it must be genuinely accessible rather than allocated to residents. The area required includes aisles and manoeuvring, which roughly doubles the bay footprint.
Visitor spaces
Spaces = ceil(units x visitor percentage)
Area
Area = spaces x area per space including circulation

This calculator takes 3 inputs: Residential units, Visitor spaces as share of units, Area per space including circulation. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
