In the canton of Geneva, objections or observations can usually be filed within 30 days of the official publication. The exact deadline is stated in each notice, and the notice is what counts.
The NovaNest Pro alert e-mails new building permit applications, filtered by canton and project type, each with a summary for professionals. It is free during the launch.
