A lot confirmation verifies one or more lots or lots of record have legal status as a property that is eligible for development under the zoning code. A lot confirmation is often undertaken to confirm lots or lots of record that have previously been combined for tax purposes. A lot confirmation does not verify accessibility to services such as water or sewer; it only confirms that the property meets zoning code standards to be eligible for development.
Applying for a Lot Confirmation
- Fill out and submit an Application/Request for Lot Confirmation
- Include a site plan, drawn to scale, showing all existing development, parking and distances from structures to property lines
- A survey is typically required when it appears that the location of 1-2 family residential development is within three-feet of the property line to be confirmed or for commercial development dependent on the type of development and available information. The survey must be stamped and signed by a registered licensed surveyor.
