Garage conversions in Harwich: Homeowners vs renters

For homeowners:

You’re responsible for applying for any necessary planning permission or building regs sign off. Most garage conversions fall under permitted development, but it’s always worth checking with your local authority.

For renters:

The rules are different. You’ll need written permission from your landlord before making any structural changes. In some cases, they may manage the job themselves. Either way, get it in writing.
