I. Purpose and Intent
This local law, using Section 421-f of the Real Property Tax Law, authorizes a partial exemption
from real property taxation of the increase in assessed value attributable to reconstruction,
alterations or improvements made to residential property, and shall apply to taxes and special ad
valorem levies, and shall not apply to special assessments.

The colloquial name of this local law, which is a verbatim adoption and implementation of Section
421-f of the Real Property Tax Law, shall be “The Home Improvement Exemption Law.”

Section 421-f of the Real Property Tax Law sets forth the following exemption criteria:
1. The property for which exemption is sought must be a one or two family residence;
2. The greater portion of the residence (as measured by square footage) after the capital
improvement must be at least five years old;
3. The capital improvement must be commenced after the date the local law or resolution is
enacted;
4. The exemption applies to reconstruction, alterations or improvements;
5. The exemption does not apply to ordinary maintenance or repairs; and,
6. The value of such reconstruction, alteration or improvement must exceed the sum of $3,000.

before the taxable status date of March 1st; and,
2. Provide sufficient documentation to the Town of Portville assessor’s office in the form of
construction contract, building permit, and receipted bills to support the cost of capital improvement.
V. Exemption Limit
The exemption shall be limited to Eighty Thousand Dollars ($80,000) in increased market value with
any additional value attributable to the new construction not being eligible for the exemption; and,
VI. Determination of Market Value
The market value of the new construction shall be calculated by dividing the increase in assessed
value attributable to the new construction by the latest State equalization rate or special
equalization rate, unless such rate is 95 percent or more, in which case the increased assessed
value shall be deemed to equal the market value.

VIII. Exemption Retention Conditions
Once the exemption has been granted, it shall not necessary to reapply for the exemption after the
initial year in order for the exemption to continue. There is no need to reapply in subsequent years,
but if the property ceases to be used primarily for residential purposes, or if title to the property is
transferred to persons other than the heirs or distributees of the owner, the exemption is
terminated. The exemption will automatically be recalculated in any year in which there is a change
in level of assessment for the final assessment roll of 15 percent or more. No local law or
resolution may repeal or reduce an exemption granted pursuant to Section 421-f until expiration of
the period of that exemption.
