"We have ordered closure of 10 lodges for non-renewal of licences and for not meeting the standards listed in licence conditions," G Kannan, Commissioner of Rameswaram Municipality said.
Only if such defaulting lodges fulfil the legal obligations would they be allowed to function again, he said.
Adequate ventilation, clean drinking water and sufficient parking space are among the requirements in licence conditions.
Also, owners of 35 houses who had been allegedly letting out their premises on rent to visiting pilgrims have been directed to stop the practice immediately as it is illegal.
