Summary
Huntington's Zoning Code lets homeowners build a detached garage sized for two or three vehicles depending on the district, but it flatly bars turning that garage into living space. The definition of "Garage, Residential" caps floor area at 300 square feet per vehicle, limits the structure to one story, and allows only storage as an extra use.
An accessory building or part of a building traditionally designed or used for the storage of motor vehicles owned and used by the occupants of the residential building to which it is accessory. In R-15, R-10, R-7 and R-5 Districts, garage space for two (2) motor vehicles may be provided for a one-family or two-family home. In R-80, R-40 and R-20 Districts, garage space for three (3) motor vehicles may be provided for a one-family or two-family home. In any other zoning district, garage space for two (2) motor vehicles may be provided for each dwelling unit. In any residence district, a detached garage shall be one (1) story and have only one (1) floor level, shall provide not more than three hundred (300) square feet for each motor vehicle accommodated and shall not exceed the gross floor area of a permitted accessory building. Nothing contained herein shall be construed to permit the use of detached residential garages as habitable space, and same is specifically prohibited. A residential detached garage may provide space for storage on the same floor.

Full Breakdown
The Zoning Code's definition of "Garage, Residential" in § 198-2 sets both a build standard and a use restriction for detached garages serving one- and two-family homes. In the R-15, R-10, R-7 and R-5 Residence Districts, a home may have garage space for two vehicles; in R-80, R-40 and R-20, three vehicles are allowed. Whatever the district, a detached garage is limited to one story with a single floor level, may provide no more than 300 square feet per vehicle it accommodates, and cannot exceed the gross floor area otherwise allowed for an accessory building.
" A residential detached garage may still hold storage space on the same floor as the parked vehicles, but finishing the space as a bedroom, den, home gym or accessory apartment falls outside the permitted use entirely, regardless of the garage's square footage. Attached garages are treated differently: § 198-59F folds an attached garage into the main building for yard-requirement purposes, though any interior conversion there still has to satisfy the Building Code and the Town's building-permit process separately. Because the garage-conversion bar sits in the zoning definitions article, a property found in violation is enforced the same way as any other zoning violation, through the Building Inspector's authority under § 198-123.
Violations & Fines
A detached garage finished out as habitable space is a zoning violation enforced by the Building Inspector under § 198-123. Conviction under § 198-125(A) brings a fine of $1,000 to $5,000 for a first offense, up to fifteen days in jail, or both; a second offense within five years raises the fine to $2,000-$10,000, and each day the conversion continues can be charged as a separate offense.
