How Gilbert Handles Sign Regulations: A Practical Guide

Gilbert maintains 121 local ordinances across all categories, and 6 of those deal specifically with sign regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Gilbert falls on the strict-to-permissive spectrum compared to other cities.

Freeway-Facing Signs

Gilbert's Land Development Code allows a dedicated Freeway Sign only on parcels of at least 15 net acres in Commercial, HVC/GVC/GBC, Office, Employment, Public Facility/Institutional or Mixed-Use districts abutting a freeway. One sign is allowed per 400 feet of freeway frontage, capped at 500 square feet and 60 feet in height.

Key details: Minimum lot size: 15 net acres. Max number: 1 per 400 ft. of freeway frontage. Max sign area: 500 sq. ft.. Setback from freeway ROW: 150 ft.. Max height: 60 ft. above grade.

Under LDC § 5.6.14 (Sign Violations), it is illegal to construct, install, attach, place, paint, alter, relocate or otherwise maintain any sign in Town, including a freeway sign, without first obtaining a sign permit. A Code Compliance Officer issues a ten-calendar-day written notice to correct a violation; an unsafe sign gets a two-day notice, and if not corrected within 48 hours the Building Official may have it removed or repaired at the sign owner's expense. Non-compliant signs are declared nuisances and may be abated, and the Town can sue in Municipal or Superior Court to recover removal costs.

Window Signs

Gilbert's Land Development Code caps window signs at less than 25 percent of the window area they're displayed in, requires no permit for a compliant window sign, and bars them on single-family residential property while allowing internal, optional illumination where they are permitted.

Key details: Max coverage: < 25% of window area. Permit: Not required if compliant. Illumination: Internal only, optional. Single-family homes: Window signs not permitted.

A window display that exceeds the 25 percent coverage threshold, or that uses illumination other than internal lighting, is not exempt and is not permit-eligible as configured; Planning & Development Services can require the display to be reduced or removed, and window signs on single-family residential property are prohibited outright regardless of size.

Digital Billboards

The Town of Gilbert's Land Development Code bans billboards outright, and the ban covers digital and electronic displays the same as static panels. Section 5.6.3 lists Billboards among the Town's prohibited sign types, and a standalone severability clause in Section 5.6.16 protects that specific ban even if a court strikes down other parts of the sign chapter.

Key details: Billboards: Prohibited Town-wide (§ 5.6.3.C). Applies to: Digital and static billboards alike. Enforcing official: Development Services Director or designee. Severability: Ban survives even if other sign rules are struck down. Adoption authority: A.R.S. § 9-462.01, Town police power.

Erecting a billboard, digital or static, violates Section 5.6.3.C's prohibited-signs list and falls under the Development Services Director's enforcement authority set out in Section 5.6.1. Because Section 5.6.16.C singles out the billboard ban for its own severability protection, a successful challenge against other parts of the sign chapter will not reopen billboards as an allowed use: the prohibition remains independently enforceable even if surrounding provisions are struck down.

This is not one of those rules that cities tend to ignore. Gilbert actively enforces its digital billboards requirements.

Holiday Displays

Gilbert's Land Development Code defines "sign" to exclude yard decorations from regulation entirely, so a seasonal inflatable Santa, pumpkin or snowman displayed at a home isn't subject to the Town's Sign Regulations chapter. The Section 5.6.3 ban on "Inflatable Signs" reaches only inflatables used to advertise a commercial or noncommercial message, not pure holiday decor.

Key details: Sign definition: Excludes "decorations visible from a public area". Inflatable Signs: Prohibited only if used to advertise (§ 5.6.3.F). Holiday decor status: Not a regulated sign under § 2.0 Terms. Dedicated ordinance: None: governed only by the sign definition's exclusion.

Because holiday decorations are excluded from the Land Development Code's definition of "sign," a residential inflatable holiday display doesn't trigger sign-permit review or the Section 5.6.3 prohibited-signs list, and there's no sign-code basis to cite it as an illegal Inflatable Sign. If an inflatable display instead carries a commercial or noncommercial advertising message, it stops being a "decoration" and becomes a prohibited "Inflatable Sign" under Section 5.6.3.F, exposing it to removal.

If you are coming from a city with tighter rules, you will find Gilbert gives residents more flexibility on holiday displays.

Garage Sale Signs

Gilbert allows up to three temporary signs for garage/carport/yard sales. Signs may be placed on private property but not in the public right-of-way or on utility poles. Signs must be removed promptly after the sale. The town's sign code was revised following the Reed v. Town of Gilbert Supreme Court decision to ensure content-neutral regulation.

Key details: Sign Limit: Maximum 3 temporary signs per sale. Private Property: Permitted on own property. Right-of-Way: Prohibited in public ROW. Removal: Must remove after sale ends. Code: Content-neutral after Reed v. Gilbert.

Political Signs

Gilbert's Land Development Code exempts political signs from its sign regulations altogether, deferring to the protections Arizona law gives them under A.R.S. § 16-1019, so the Town does not impose its own size, timing or permit rules on political signs the way it does for commercial signage.

Key details: Exemption basis: A.R.S. § 16-1019. Also exempted: Sign walkers under A.R.S. § 9-499.13. Local permit required: No. Governing sign chapter: LDC § 5.6.2 Exempt Signs.

Because political signs are exempted rather than separately regulated, Gilbert does not cite them under its own Sign Regulations chapter; a dispute over placement, size or timing is governed by A.R.S. § 16-1019's own state-law limits, which the Town's Code Compliance staff apply rather than a local sign-permit violation.

Gilbert is more permissive than most cities when it comes to political signs. That said, there are still limits.

The Bottom Line

Compared to many U.S. cities, Gilbert gives residents more room on sign regulations. 2 of the 6 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
