Monroe County, FL Home Business: Signage Rules (2026)

Monroe County Land Development Code Section 134-2(d) sets two related standards the Planning Director checks before issuing a home occupation special use permit: activities associated with the home occupation cannot be visible from any other residential dwelling unit, and if the business uses an accessory structure, that structure has to be covered and enclosed rather than open to view. Layered on top of that visibility rule, no sign advertising the home occupation may be displayed on the premises at all, so a home business cannot use yard signs, window signs or any other on-site advertising to draw attention to itself.

These standards work together with the separate ban on putting the residence's address on business cards or advertising materials under subsection (d)(5): the county's goal is a home occupation that a passerby on the street cannot identify as a business at all, whether by sight, by sign, or by published address. The rule applies to every home occupation permit issued in the unincorporated Keys, from Key Largo to Big Pine, regardless of the type of business. A permit holder who puts up a sign, or who runs a visibly business-branded operation from an open carport or unenclosed shed, is out of compliance with the permit's own conditions.

The Planning Commission can revoke the permit after a public hearing if the holder is found to have violated any provision of Section 134-2, including this sign and visibility standard.
