Sign Regulations in Jupiter, FL

If you live in Jupiter or are thinking about moving there, sign regulations are one of those things you probably won't think about until they affect you directly. Jupiter has 4 specific rules on the books covering different aspects of sign regulations, and some of them might surprise you.

Garage Sale Signs

A residential garage sale in Jupiter does not need a special permit, but the Code limits a household to two sales a calendar year. In the Abacoa-area Mixed Use Development District, the matching sign rule allows just one on-site sign, two square feet, for a single day, sunrise to sunset.

Key details: Sales per residence, per year: Two, no permit needed. Sign size (MXD): 2 square feet maximum. Sign duration: One day, sunrise to sunset. Frequency (MXD sign rule): Twice per calendar year. Sign location: Must be on sale property.

A garage sale sign left up outside the sunrise-to-sunset window, oversized beyond two square feet, or a household exceeding two sales in a calendar year is subject to code enforcement action, with removal or fines referred to the code enforcement board or a special magistrate under Sec. 8-40(a), up to $1,000 per day for a first violation.

The rules around garage sale signs in Jupiter lean permissive, but that does not mean anything goes.

Window Signs

A Jupiter commercial business cannot cover more than 25 percent of its street-facing window area with signage, display racks, merchandise or other opaque material. The business can spread that allowance across several windows, but no single window may be covered 75 percent or more.

Key details: Total window coverage cap: 25 percent of street-facing area. Single window cap: Must stay under 75 percent. MXD temporary window sign: 5 sq ft or 25% area, 20 days max. Applies to: Each individual commercial business. Counted as a window sign: Anything within 12 inches of the glass.

A commercial window covered beyond the 25 percent threshold, or a single window exceeding 75 percent coverage, is enforced through the town's code compliance division, with unresolved violations referred to the code enforcement board or a special magistrate under Sec. 8-40(a) for fines up to $1,000 per day for a first violation and $5,000 per day for a repeat violation.

Political Signs

Jupiter caps temporary political signs at one per candidate or issue per residential lot, limits them to six square feet on residential property and 16 square feet on nonresidential property, and bars illumination, medians, and placement on trees or utility poles.

Key details: Residential sign limit: 1 per candidate/issue, 6 sq ft. Nonresidential sign limit: 1 per 200 ft frontage, 16 sq ft. Max height: 6 feet above road crown. Nonresidential install window: 30 days before election. Removal deadline: 5 days after election (nonresidential).

Leaving a nonresidential political sign up more than five days after the election, exceeding the one-sign-per-candidate limit, or fastening a sign to a tree or utility pole violates section 27-3361. The town first sends certified-mail or hand-delivered notice giving 24 hours to remove an overdue sign; an unremoved sign is deemed abandoned, and the town can remove and dispose of it and bill the actual removal cost to the applicant or property owner.

Digital Billboards

Jupiter limits freestanding changeable-copy signage to eight square feet per face townwide and reserves full electronic message boards, LED, LEP or OEL, for museums, government buildings, performing arts theaters and movie theaters. A performing arts theater's electronic sign must dim automatically at night, change copy no more than twice a day and stay 150 feet from homes.

Key details: Freestanding changeable-copy cap: 8 square feet per sign face. Performing arts theater cap: 15 square feet. Message change limit: No more than twice per 24 hours. Residential setback: 150 feet from any residential unit. Nighttime brightness limit: 0.3 foot-candles over ambient light.

Erecting an electronic display sign without a town building permit violates Sec. 27-3358(c). The Department of Planning and Zoning may order removal of any sign that is unsafe, exceeds these size or brightness limits, or lacks a valid permit, giving the permittee 30 days' written notice to comply before the town removes or alters it at the owner's expense under Sec. 27-3358(i). A sign that presents a safety hazard or blocks a right-of-way can be taken down without notice under Sec. 27-3358(g).

Compared to other cities, Jupiter takes a harder line on digital billboards. The enforcement and penalty structure reflects that.

The Bottom Line

Jupiter's sign regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Jupiter is broadly strict or permissive.
