Every outdoor sign in Miami is governed by the municipality’s sign ordinance, which sets how large a sign may be, how tall it may stand, how far it must sit from the property line, whether it may be illuminated, and which sign types are permitted in each zoning district. This page summarizes those requirements in plain language and links each value back to the section of the Miami code it came from.
Sign rules here are layered. The base zoning district — commercial, industrial, or residential — sets the default limits, and overlay districts such as historic or downtown districts can tighten them further. Because the most specific jurisdiction controls, a freestanding monument sign on a commercial parcel and a wall sign in a historic overlay can face very different limits even on the same street in Miami.
Use the figures below as a fast first check, then run a full address lookup to confirm the exact limits for a specific parcel in Miami, Florida. The full report also covers permit requirements, prohibited sign types, and illumination rules — each cited to the source ordinance so your permit application can reference it directly.
Before you order or install a sign in Miami, confirm three things: the maximum sign area and height allowed in the parcel’s zoning district, the minimum setback from the right-of-way, and whether the sign type you want — freestanding, monument, wall, projecting, or awning — is permitted there at all. Many permit denials come from missing a setback or an overlay-district restriction rather than from the size of the sign itself, so checking the governing section before applying saves a costly resubmittal.

The Historic and Environmental Preservation Board, in accordance with Article 7 of the Zoning Ordinance and Chapters 23 and 62 of the City Code, may determine that a sign is of historic significance upon finding that said sign contributes to the cultural, historic, or aesthetic character of the City, neighborhood, or streetscape, due to its construction materials, age, prominent location, unique design, or craftsmanship from another period.
