Documents you need to request official building plans

Visit the Records Management Division in-person with these affidavits and letters.

You must bring these documents with you to apply for copies of official building plans.

The documents you need depend on the ownership of the building.

Bring a copy of the Affidavit of the Building Owner. We also have copies in the office. We will ask you to sign this form in the presence of a staff member.

A copy of the recorded grant deed may be needed if the property was purchased recently.
