Fair Lawn's Land Development Ordinance (Chapter 125, codified on eCode360) does not contain a stand-alone accessory dwelling unit (ADU) ordinance. The R-1-1, R-1-2 and R-1-3 Zones permit only one one-family dwelling per lot with no other principal use; two-family dwellings are permitted only in R-2 (and zones above), and accessory uses must be customarily incidental to the principal use.

Converting interior garage space into habitable living area for the existing household is treated as a change of use that requires a Borough zoning permit ($45 fee for garage conversions per the Borough fee schedule) and a New Jersey Uniform Construction Code (N.J.A.C. 5:23) permit issued by the Fair Lawn Construction Code Official.
