Hi there,

Can anyone help me with accessible parking calculation?

If there are 1120 parking spaces, according to IBC  I would need 20 plus 1 plus 0.2 (21.2 spaces). Does this mean I need 21 accessible spaces or 22? At what point can you round down or up?

I just completed Erik Walker's practice exam and one of the questions was similar (Q81 - loading dock calculation), He rounded down to get answer. It says 3.4 loading spaces, ROUNDED DOWN to 3 total loading spaces. 

I always round up the parking count....so am a bit confused now. If anyone could help me with this, I would greatly appreciate it.

Thanks!

  I would go with 22, it supposes to round up not down to be safe; at least it is the way I found it in every question about that

  Megumi,

  When it comes to code occupant loads, plumbing counts, ADA parking spots, etc... you always round up. If after doing an ADA calculation your parking count came out to 21.2, then you need 22 accessible parking spaces.

  Good luck!

  Yes, in all life-safety and regulatory issues you take the conservatives/safe path - so round up, more stalls, thicker walls, more SF, wider egress, etc.
