Nairobi Governor Johnson Sakaja has issued a final warning to property owners with unauthorized buildings, urging them to utilize a limited window to legalize their developments or face legal action. This initiative aims to regularize unapproved structures under the new Regularisation of Unauthorised Development Act, 2025, ensuring urban planning and safety standards are met.

• Affected areas include Ruai, Kasarani, Mwiki, Roysambu, and parts of Embakasi.
• Applications must be submitted through registered professionals via the Nairobi Planning and Development Management System (NPDMS).
• The county will launch a citywide crackdown after the deadline to bring thousands of unauthorized structures into compliance.
