    Red Bluff Inspectors stated that the symbol is the profile (Wheel Chair) not the border. Referanced were DOT 22511.8 (3) figure 3B-19 (CA) & 2010 CBC 1129B.4 (2), Symbol shall be 36″ w/contrasting outline.

    Can you confirm?

      I suppose that an inspector could make that interpretation, because I’ve never found a dimension string associated with an ISA diagram in the CBC, ADA, CALTRANS or the DMV. Given that the dimensions given in the code are for width and height, it seems logical that the dimensions would apply to the width and height of the entire square symbol – not just the wheelchair figure. Also, accessible building entrances are required to have a 6″ ISA adjacent to the door, and it’s definitely accepted practice that the 6″ applies to the entire sign, not the wheelchair figure.
      I hope that helps.

    What do you know about painting the wheelchair facing to the left when looking at it? My apartment complex hired a contractor that painted all of our parking spots that way. I’m assuming that would make all the spots “technically” not handicapped anymore. I need assistance finding the regulations to show my complex management IF they are incorrect with all the parking spots. Can you help me? BTW, I live in San Antonio, TX. Thanks – – David M.

      I occasionally see an ISA (International Symbol of Accessibility) facing left, out there in the real world. There’s nothing technically wrong with having the ISA face left, it’s just “grammatically” incorrect.

    Here is a link to a document put out by CALTRANS in 2012 on the design of the ADA parking space ISA symbol. It is very clear on the design and demission.

      That’s fine – but the dimensions f/ both the ADA & the CBC require a parking ISA to be 36″x36″ min. – which is different than Caltrans requirements.
