Planning and Building queries will now be heard at La Motte Street.
The helpdesk has left South Hill to move into the States new ‘one front door’ building.
Householders and the general public who have questions about building work on local properties, want to drop off applications or view location plans and historic files will need to head for Philip Le Feuvre House.
South Hill is now closed except for appointments.
Planning joins Taxes, Treasury, Passports and Customs in relocating, as part of Chief Executive Charlie Parker’s plan to bring all front-line customer services to one place.
There are more details about the move on the States of Jersey website.
