Zoning codes specify a parking ratio per use type. Plug in floor area and use, get total required spaces — plus ADA accessible stall count.
FAQ
ADA minimum? +
Per ADA: 1 accessible space for the first 25, then 1 per 50 up to 200, then 1 per 100 thereafter. 1 in 6 must be van-accessible (8' wide aisle).
Are these defaults universal? +
No — every municipality writes their own. Many urban areas have eliminated parking minimums entirely (Buffalo, Minneapolis, etc.). Check your code, don't trust defaults.
Stall dimensions? +
Standard: 9' x 18'. Compact: 8' x 16'. ADA: 8' x 18' + 5' access aisle (8' aisle for van). Drive aisles: 22-24' for 90° parking.
