In valuing a structure the Assessor takes into consideration the outside measurements, type of construction, year built, condition, etc.
After all data is gathered, appropriate cost tables, depreciation, and neighborhood factors are applied that result in a value. The land is valued separately and takes into consideration such things as location, use, and home site value as well as road and water frontage and any Right-of-Way associated with the land..
The Assessor's Office does consider actual cost, IF INFORMATION IS AVAILABLE! Supplying invoices of all materials, quotes on construction / land prep are all helpful in ensuring we have applied the correct cost. If you claim self-built, you will be requried to provide a certified letter stating the hours worked on the project to include the number of all those who helped in construction.
