Frequently Asked Questions

Does this exclusion apply to the regular tax bill?

No, this excludes only the supplemental assessment for the new construction.  Any new construction that is partially complete on January 1st (lien date) will be included in your regular yearly tax bill. 

How is the date of the start of new construction determined?

Construction is considered to have started if any physical activities on the property have begun. This includes clearing and grading of land, excavation, layout of foundations, installation of temporary structures and demolition of existing structures or fixtures.
