Policy CTY 7 – Dwellings For Non-Agricultural Business Enterprises
Planning permission for a dwelling in connection with an established non-agricultural business enterprise requires clear demonstration of a site-specific need making it essential for an employee to live at the work site. The dwelling must be located beside or within the business boundaries, integrate with existing buildings, and be subject to occupation restrictions.
Planning permission will be granted for a dwelling house in connection with an established non-agricultural business enterprise where a site specific need can be clearly demonstrated that makes it essential for one of the firm's employees to live at the site of their work.
Where such a need is accepted the dwelling house will need to be located beside, or within, the boundaries of the business enterprise and integrate with the buildings on the site.
Planning permission granted under this policy will be subject to a condition restricting occupation of the dwelling for the use of the business.
