If searching by an address do not spell the street name or the direction out and do not use punctuation. Example: 1234 W 52nd Ave. If you are searching for historical permits issued before 2013 review the attachment for PREH13 permits associated with the address.
Permit numbers have a pre-fix of the type of permit and the last two digits of the year that it was applied in. For example RES16, permit type is for residential and was applied for in 2016.
