A building or structure shall not be used or occupied in whole or in part, and a change of occupancy of a building or structure or portion thereof shall not be made, until the building official has issued a certificate of occupancy therefor as provided herein. Issuance of a certificate of occupancy shall not be construed as an approval of a violation of the provisions of this code or of other ordinances of the jurisdiction.

  2. Accessory buildings or structures.

R110.2 Certificate issued.

After the building official inspects the building or structure and does not find violations of the provisions of this code or other laws that are enforced by the department, the building official shall issue a certificate of occupancy containing the following:

  1. The permit number.

  2. The address of the structure.

  3. The name and address of the owner or the owner’s authorized agent.

  4. A description of that portion of the structure for which the certificate is issued.

  5. A statement that the described portion of the structure has been inspected for compliance with the requirements of this code.

  6. The name of the building official.

  7. The edition of the code under which the permit was issued.

  8. Where an automatic sprinkler system is provided and whether the sprinkler system is required.

  9. Any special stipulations and conditions of the building permit.

R110.3 Temporary occupancy.

The building official is authorized to issue a temporary certificate of occupancy before the completion of the entire work covered by the permit, provided that such portion or portions shall be occupied safely. The building official shall set a time period during which the temporary certificate of occupancy is valid.

R110.4 Revocation.

The building official is authorized to suspend or revoke a certificate of occupancy issued under the provisions of this code, in writing, wherever the certificate is issued in error, or on the basis of incorrect information supplied, or where it is determined that the building or structure or portion thereof is in violation of the provisions of this code or other ordinance of the jurisdiction.
