Full Breakdown
401(u) of Fairfield's Community Preservation Code splits home vehicle work into minor and major repair and regulates each differently. Minor repair covers alternator, generator, starter, water pump, fuel pump, battery, or brake work, a basic tune-up limited to distributor cap, rotor and spark plug replacement, oil and filter changes, fan belt or hose changes, lamp replacement, flat tire repair, lubrication, and spot painting. Minor repair in a residential zone is unlawful and a public nuisance if the vehicle is not registered to a current occupant of the premises, or, even when it is registered to a resident, if the work is done outside a fully enclosed structure for more than forty-eight consecutive hours, or on more than two vehicles at once by the same person.
Major repair, defined to include engine removal or rebuilding, internal component repair, transmission or differential or axle work, dismantling, and body work, is unlawful in a residential zone unless the vehicle is registered to a current occupant, the work happens entirely inside a fully enclosed structure, and no more than two vehicles are being repaired at the same time on the premises. Subsection (u)(4) bars body painting, including spot painting, in a residential zone regardless of these conditions. 205 penalty ladder as other nuisances: an infraction fine up to $100 for a first violation, escalating to a misdemeanor with a fine up to $1,000 or up to six months in jail for a second violation within a year.
Violations & Fines
Repairing a vehicle not registered to a resident, working outside an enclosed structure for more than 48 hours, servicing more than two vehicles at once, or any body or spot painting in a residential zone violates Section 27.401(u) as a public nuisance. A first violation is an infraction with a fine up to $100; repeat violations within a year become misdemeanors punishable by up to $1,000 or six months in jail.
