The person has to submit his construction plan along with his application for construction of building before the Municipal Corporation. The Muncipal corporation will scrutinize the application and as well as the proposed building plan. Thereafter, if the Municipal Corporation is satisfies, that the proposed building plan is in accordance with law and building rules, then the Muncipal Corporation will be sanction building permission. There is limited period for that [ I think i.e. 30 days ], in the stipulated period, if the Municipal Corporation is not sanctioned building permission, there will be applied the provsion of "Deemed Permission". The word "deemed permission" means "it is deemed that the permission is granted". Without any copy / sanction of permission, the aspirent will construct his building in accordance to the submitted proposed building plan. I think you are a lawer, kindly see the Hyderabad Muncipal Corporation Act for deemed permission provision.
