Editor's Note: Section 3 of this local law stated as follows: "Existing accessory apartments lacking a certificate of occupancy may achieve conforming status without a violation being prosecuted by applying for a building permit within one year of the effective date of this local law and complying with the requirements of this section."
[Amended 4-23-2002 by L.L. No. 7-2002]
A. 
In order to construct an accessory apartment, the applicant shall apply for and receive a building permit from the Town Building Department in the manner of all other applications for building permits.

Where the application entails structural alteration of the dwelling, the applicant shall also pay all other applicable fees as provided under § 123-12 of the Town Code.
[Amended 1-22-2019 by L.L. No. 3-2019]

A rental permit in accordance with Chapter 270 of the Town Code must be issued prior to the occupancy of an accessory apartment. For those accessory apartments receiving building permit approval after January 1, 2019, at the time of application for a rental permit, or at the time of renewal of the permit, the owner shall provide a fully executed lease agreement or other documentation that demonstrates that the rent does not exceed the annual fair market rent (FMR) for Suffolk County as established by the Department of Housing and Urban Development (HUD) and that the tenant’s income meets the standards established for low-moderate income or middle income as defined under Chapter 216 of the Town Code.

[Amended 8-22-2000 by L.L. No. 12-2000; 4-23-2002 by L.L. No. 7-2002; 12-23-2003 by L.L. No. 78-2003; 12-13-2005 by L.L. No. 68-2005]
A. 
Owner occupancy required. The owner or owners of the lot upon which the accessory apartment is located shall reside within the principal dwelling or the accessory apartment, and said dwelling or apartment shall be considered the owner's domicile or principal place of abode. No other owner or owners shall own a larger percentage, collectively or individually, than the owner-occupant. Nothing within this Subsection A shall be deemed to apply to lots held in ownership by the Southampton Housing Authority or any not-for-profit agency to which the Southampton Housing Authority transfers title. The exemption of such not-for-profit agency must be approved by the Southampton Town Board, and such exemption will be determined on a lot-by-lot basis. Such required approval shall in no way affect the management of the lot by the Southampton Housing Authority.
[Amended 8-22-2006 by L.L. No. 46-2006; 6-9-2009 by L.L. No. 26-2009]
B. 
An accessory apartment shall be permitted in a structure that has been issued a certificate of occupancy or a certificate of compliance, or be entitled to the issuance of a certificate of occupancy by virtue of a preexisting status, or is new construction that complies with Chapter 123, Building Construction; Section 164, Fire Prevention; and § 330-5, Definitions: "dwelling, two-family detached" and "accessory apartment." Notwithstanding the above, no permit shall be processed until the lot has a certificate of occupancy for an existing single-family dwelling.

A nonconforming lot may be eligible for an accessory apartment, provided that the lot area is not less than 80% of the required lot area for the applicable zone district, but in no case less than 30,000 square feet unless the lot is located in a CDP that meets the above-referenced density requirement; then the nonconforming lot shall be not less than 20,000 square feet. All other dimensional nonconformities shall not be less than 70% of the required setback or lot width. A lot with a nonconformity of a greater degree shall not be eligible for an accessory apartment under this article. Any such request shall be prohibited and can only be treated as an area variance by the Board of Zoning Appeals.
