Legality of town changing property classification from

[Christopher Guerriero]

In 2018, the township of Ewing NJ changed the definition of a dwelling unit to "houses with 5 or less bedrooms". Houses with 6 or more bedrooms became defined as "Commercial Rooming Structures". "Commercial Rooming Structures" must be registered as single family rentals and cannot be used as boardinghouse or roominghouses. The tax assessor changed the classification for all houses that fit the description from class 2 residential (1-4 family) to class 4c (apartments). Is it really legal for the tax assessor to take a home someone has owned for 20 years and change it to Commercial property, limiting his refinance and resale ability. It seems like this is a situation where you would be grandfathered in, am I correct. What kind of loan do you even get to purchase a made up property type? Let me know what you think.
