Summary
Unincorporated Putnam County requires every building light installed for security or looks to be a fully cut-off fixture, so no beam ever shines upward into the sky, and caps fixture height at 30 feet. Planning and Development Services can grant a narrow administrative deviation only when the applicant proves a genuine security need and adds screening for neighbors.
(a)Height. The maximum height of light fixtures, except as otherwise regulated by this section, shall not exceed 30 feet.(b)Light pollution. All building lighting for security or aesthetics shall be fully cut-off type, not allowing any upward distribution of light.(c)Variance. The lighting requirements in this section may be modified by administrative deviation provided that the applicant establishes that such an increase meets the following standards:(1)Any increase in intensity is reasonably required for security purposes for the use or for conducting the permitted outdoor use;(2)Any increase in intensity will not result in a nuisance to adjoining properties and does not interfere with the lawful use and enjoyment of adjoining properties; and(3)Necessary screening will be erected or exists and maintained to reduce the impact of any increase in intensity on adjoining properties.(4)The parcel on which the lighting is to be located is not within the military restriction overlay zone (MROZ).
Full Breakdown
Section 45-601 of the Putnam County Code, part of the Land Development Code's outdoor lighting division, sets two flat numeric limits before any variance analysis begins. First, no light fixture anywhere in unincorporated Putnam County, except where another LDC section regulates it specifically, may rise higher than 30 feet. Second, any building lighting installed for security or aesthetic purposes has to be fully cut-off type, the code's own term for a fixture that blocks all upward light distribution, the classic dark-sky shielding standard used to keep glow from spilling into the night sky over the St.
Johns River corridor and Putnam's rural subdivisions. The county does not leave a blanket exception: a property owner who wants brighter or taller lighting than the base rule allows must apply for an administrative deviation and satisfy four separate findings before Planning and Development Services will approve it. The applicant has to show the added intensity is reasonably needed either for security or for the specific outdoor use taking place, that the increase will not create a nuisance or interfere with a neighbor's use and enjoyment of their own land, and that screening is already in place or will be installed to blunt the added glare.
The fourth test is a hard geographic bar rather than a balancing factor: no deviation of any kind may be granted if the parcel sits inside the county's military restriction overlay zone (MROZ), regardless of how strong the security justification is.
Violations & Fines
Section 45-601 sits in the Land Development Code, so a fixture that throws light upward or exceeds the 30-foot cap is a code violation Planning and Development Services can flag during permitting or from a neighbor complaint. Because chapter 2's code enforcement provisions route contested cases to a special magistrate rather than a court, an owner who installs noncompliant lighting risks an order to retrofit the fixture with cut-off shielding or lower it to the 30-foot limit, and any deviation obtained on false claims can be revoked.
