How close to the property line can I put an air conditioner?

Wednesday, August 31, 2022

There are no building code specs for minimum distance of an air conditioning condenser (outside unit) from a property line. But, because the noise generated by a condenser can be annoying to someone in an adjacent property, some communities have local ordinances that address the problem. For example, the City of Los Altos, California, requires that an air conditioner be a minimum of five feet from the property line for units creating less than 64 decidels of mechanical noise, and gradually ramps that distance up to 22 feet for 74-decibels.

Coral Gables, Florida, takes a slightly different approach. They allow no more than 55 decibels as measured at the lot line, and the condenser must be however far away is necessary to meet that standard. Because condenser units tend to become noisier as they age, it’s possible for one to age into non-compliance after a decade or so.

Other municipal jurisdictions around the country have similar ordinances. And it is typical for many of them to require that the condenser be located so it is not visible from the street.
