What is a Legal Non-Conforming Use?
Non-Conforming Rights Determination Handout
A non-conforming use is defined as any lawful use of a building, structure, or land which does not conform to the zoning regulations where it is located. Non-Conforming uses usually occur when the use conformed to zoning regulations when it was originally established became non-conforming due to a zoning change or annexation.
In most cases, if you are able to establish that the property’s current use began before zoning changes made it non-conforming, you have a right to continue that use. That right is sometimes referred to as a “Grandfather Right.”
Uses that have been in existence, but never were lawfully permitted are not legal non-conforming uses.
How Do I Obtain Proof?
Obtaining proof of a pre-existing non-conforming use can be done in several different ways.
- First you must establish when the use became in existence
- Second you must establish that the use was a permitted use per the laws at the time it was established.
The following is a list of some (but not all) of the types of records which are accepted as proof of the use’s existence:
- A permit issued clearly identifying use at the subject address.
- If the property is rented, receipts showing dates of use.
- Receipts showing services or goods provided if the use is a type of business.
- Tax records.
- Statements from utilities, such as power, water or gas, which indicate time and amount of use.
- Notarized statements from neighbors who have observed the non-conforming use over the required period.
