Planning permission in Watford

Most garden rooms used incidentally to the house can be built under permitted development, subject to the size, height and position limits. Depending on your address, your planning authority will be Watford Borough Council, Three Rivers District Council, Hertsmere Borough Council or Dacorum Borough Council. Conservation areas and listed buildings have extra restrictions. We give guidance at your free survey and can recommend an external planning consultant if an application is needed.
