Wireless Resiliency and Flexible Investment Act of 2023

This bill requires local governments to automatically approve certain small modifications to existing wireless towers and base stations (like adding backup power for public safety or hardening structures) within 60 days, unless they provide specific written reasons for denial. It defines "eligible" modifications as those not changing physical dimensions and directly benefiting public safety, such as improving resiliency. Local governments cannot demand extra documentation beyond publicly listed requirements and must follow strict timelines for incomplete submissions. Wireless companies seeking these modifications gain a clearer, faster approval process under federal enforcement.
