Granny flat and annexe planning permission in Jersey.

How It Works

We confirm whether your annexe requires a householder application, change of use, or both.

Planning Note
Jersey planning policy requires annexes to remain ancillary to the main dwelling — they cannot be separately sold or independently let without further consent.
Frequently Asked Questions
New Builds & Outbuildings we have taken through planning
Garden Room and Home Office
“I needed a timber office built at the end of the garden. Even though it was small, our parish boundary rules made it complicated. They drew up proper scaled plans and got full approval without a hitch.”
Demolition and Rebuild
“Replacing an old bungalow with a modern family home involved a lot of discussion with the planning department. Having a professional handle the meetings and amend the drawings made all the difference.”
Oak Frame Carport
“They designed a traditional oak frame carport for our driveway. The plans were drawn up within days and submitted straight to the island planning portal. Very smooth process throughout.”
