In my community, prior to the sale of any commercial, office, industrial, or multi-family property, the seller or their agent is required to obtain a Zoning Certificate. This certificate is a verification of the legal zoning status of the property in all aspects of the zoning code. This way, the buyer is aware of the total legal status of the property and won't have any surprises later one when they try to change the property or expand it's use.(if they actually read the certificate).
For this certificate, we charge $95 for review and require the submittal of an accurate, scaled site plan that shows the as-built condition of the property.
Usually, this is a quick review that can be done within an hour from the submittal. This process has helped slightly to identify illegally used property, or property that is legal-non-conforming.
Do any other communities do something like this or similarly?
