Certificate of Lawfulness

There are two types of Certificate of Lawfulness:


For an existing use or development (Section 191). This is commonly used to demonstrate that a use or development has been in existence for a certain length of time and therefore becomes lawful by default. For applications relating to residential matters this is generally 4 years, or 10 years for commercial/agricultural applications.


For a proposed use or development (Section 192). This is very useful to ensure that a proposed residential extension falls under permitted development (PD) rights (as set out under the General Permitted Development Order).
