Legal Basis

Bangladesh National Building Code (BNBC) 2020 UNVERIFIED
Section Part II, Section 3.2.1 — Validity of Permits from the Date of Issuance
(a) Land use certificate 24 months; (b) Large and specialized project permit 24 months; (c) Building permit 36 months (unless construction up-to plinth level is done); (d) Occupation certificate Perpetual (unless any change in use and physical properties)

Building360 interpretation — not legal advice: Defines the validity periods for each permit type. A building permit lapses after 36 months if plinth-level construction has not begun. An occupancy certificate remains valid perpetually unless the building use or physical properties change.
