What determines the year of a house?

Sunday, July 22, 2018

When the construction of a home is completed and all the final inspections are done, the local building department issues a Certificate of Occupancy, also called a “C.O.” in the building trades, which literally means that it is now allowed to be occupied. The date of the Certificate of Occupancy determines the year of the home.

   The Alachua County Property Appraiser’s Office provides this definition of “actual year built”: 

The year that a building on the property was originally constructed. The year 1900 is used when no year of construction is on file.

    You might see an “effective year built,” which is essentially an adjustment of the age of the house made by the property appraiser based on its condition. To find out more, go to our blog post ”What is the difference between actual and effective year built?”

   If you are trying to figure out the age of an older house, see our blog post ”How do you find out when the house was built?”

    It’s also worth noting that the date that the building permit was issued determines what version of the building code applies to the construction of the home, and it can easily be a year earlier than when the Certificate of Occupancy was issued.
