Summary
No new or altered building in Buffalo can be occupied until the Commissioner of Permit and Inspection Services issues a certificate of occupancy after a final inspection. The Commissioner must act within 30 days once all work and inspections are complete, and a conditional certificate can cover partially finished work.
No building hereafter erected shall be used or occupied in whole or in part until a certificate of occupancy shall have been issued by the Commissioner. ... When, after final inspection, it is found that the proposed work has been completed in accordance with the applicable ordinances, rules and regulations and also in accordance with the application, approved plans and specifications filed in connection with the issuance of a building permit, the Commissioner shall issue a certificate of occupancy upon the form provided by him. ... The Commissioner shall act to issue or deny an application for a certificate of occupancy within 30 days after written application therefor is made if all work has been completed and final inspections can be made.
Full Breakdown
City Code § 129-1 bars occupying any newly erected building, or any enlarged, extended or altered building, until a certificate of occupancy is issued, and bars changing a building's use or occupancy without a new certificate authorizing the change (enlargements to one- and two-family homes are excused only if the original floor area grows by 25% or less). Under § 129-2, the owner or agent applies on the Commissioner's form and may have to submit a licensed surveyor's survey, as-built drawings for any deviation from approved plans, and an affidavit from a registered architect or licensed engineer confirming the structure was built substantially as approved and complies with Chapter 103 Articles II and III, Chapter 129, Chapter 165 Article IV, Chapter 186, Chapter 263 Article III and Chapter 326 Article II.
Since October 18, 2016, applicants must also certify awareness of federal lead-paint disclosure rules, and § 129-3(F) bars issuing any certificate to a property with unremediated lead-based paint violations until a licensed lead inspector's letter of compliance or a licensed risk assessor's one-year letter of interim control (renewable only once) is on file. Under § 129-3(A)-(C), the Commissioner issues the certificate only after a final inspection confirms the completed work matches the approved plans and applicable ordinances, must act within 30 days of a complete written application once final inspections can be made, and must order the work completed if it fails inspection rather than issue the certificate.
Section 129-3(E) lets the Commissioner issue a conditional certificate before all work under the permit is finished, if the completed portion can be safely occupied, for a stated period that can be extended for good cause. A certificate issued through an error of fact or law is void under § 129-4, and § 129-5 sets separate Chapter 175 fees for new, altered and existing structures, with no fee for a standard new-construction certificate unless a conditional certificate is requested.
Violations & Fines
Occupying a building before the certificate of occupancy is issued violates § 129-1 and can bring a stop-occupancy order from the Commissioner of Permit and Inspection Services plus penalties under Chapter 137's fine schedule for code violations. A certificate obtained or issued through an error of fact or law is void under § 129-4, exposing the owner to enforcement as if no certificate existed at all, and any property with unremediated lead-based paint violations is barred outright from receiving a certificate under § 129-3(F).
