ANSWER: I don’t think you need to worry about signage height on existing signs anywhere but CA if they comply with the 2010 ADA Standards. They can all vary from jurisdiction to jurisdiction, but those will be building code and city ordinance issues. If you have to repair or replace the signs, they need to be 60″ minimum. You should always check local jurisdictions for any variances that would push the signs higher.
