Will my tax assessment increase if I construct an improvement to my house?

Yes. The following improvements will increase your assessment.

  • Kitchen remodeling
  • Bath remodeling
  • New exterior siding and veneers
  • Sun deck - portico - porch addition
  • In-ground swimming pools
  • Plumbing alteration, modernization and tiling
  • Installation of masonry patios
  • Finish basement for recreation rooms, laundry rooms, and game rooms, etc.
  • Central air conditioning
  • Finish attic for additional rooms of any kind
  • Additions to house for rooms of any kind, garage, greenhouse, etc.

It is only logical that an improvement to your home as described above will result in an
increased selling price of your home and therefore, your property tax assessment will
increase. This will take the form of an added assessment tax bill that you will receive in
the mail at the end of October after the improvement is substantially completed for its
intended use. This bill shall be payable on November 1, February 1 and May 1 and then
the added assessment amount will be included in your annual tax bill received in June
for the new tax year.

Therefore, just as you planned ahead for this improvement, you
should also plan ahead and set aside funds for the added assessment tax bill.
The added assessment is the amount of the difference between the property
assessment before the improvement and the value of the entire property after the
improvement. It does not reflect the cost of the amenity itself or the cost of the project.
If you did not receive an Added Assessment Tax bill for work completed in the previous
year, you will receive an "Omitted Added" Assessment bill in addition to an "Added
Assessment" bill the year following the improvement.

Please note: Not scheduling a final inspection for your building permit does not delay
the added assessment tax bill.
