A real estate developers’ association has urged the aviation authorities to speed up the issuance of no-objection certificates for construction projects. Delays in granting these approvals are affecting construction timelines and significantly increasing project costs in the city, the association said. In a formal representation sent to airport officials, the association stated that developers are facing prolonged processing times for clearances, even when applications fully comply with prescribed height and obstacle limitation norms. These delays are impacting statutory approvals from planning agencies, leading to the postponement of several projects. This, in turn, raises costs and hampers overall urban development, the association noted, pointing out the cascading impact on the real estate sector. While acknowledging the importance of aviation safety, the association stressed the need for greater clarity and predictability in the approval process. It suggested the introduction of indicative timelines, better communication regarding application status, and a coordinated mechanism to help developers plan projects more efficiently. The body also expressed willingness to engage with authorities to better understand procedural requirements and identify ways to streamline the system. Developers have additionally sought faster clearances from defence authorities in areas with military presence. In fast-growing localities such as Avadi and Tambaram, several buildings are reportedly awaiting approvals, slowing development in these rapidly expanding zones.
