Phoenix sign permit — is your storefront sign over the limit?

Phoenix keeps wall signs simple: under §705, you get 1 square foot of sign for every linear foot of your building or suite, figured separately for each elevation. Every business is guaranteed at least 50 sq ft even with a narrow storefront, and the ceiling is 500 sq ft (§705 Table D-1). Across the desert in Nevada the arithmetic changes completely — see the Las Vegas sign rules before you reuse a Phoenix design there. A 120-foot frontage gets 120 sq ft; a 30-foot shop still gets the 50 sq ft floor (§705 Table D-1).

Table D-1 caps a commercial wall sign at 25 feet high, or no closer to the roofline than one-half the sign’s vertical dimension; anything over 56 feet needs a comprehensive sign plan. The catch is the special areas. The Downtown Redevelopment Area sign district has its own sign regulations (§705), and off-premise signs are barred in historic preservation districts and scenic corridor overlays (§705); in a historic preservation (HP) district, no permanent sign may be erected or changed in exterior appearance until the Historic Preservation Officer, HP Commission or City Council approves the plans and issues a Certificate of No Effect or a Certificate of Appropriateness (§811(E)), and the sign permit is deferred until that certificate is obtained (§812(A)). The district’s design guidelines may change the §705 standards for size, height, placement, number, materials and lighting of signs, but not the safety or permit provisions (§811(D)). This tool applies the citywide §705 rule and flags when to check with a pro.

Phoenix guarantees every business a floor on wall signage, so the real decisions are height and district — both of which can push you off the standard track.

This tool is a screening aid. For permits and the binding code, go straight to the city:

Phoenix Sign Permits (Planning & Development) — applications, fees, and Section 705 of the Zoning Ordinance.

The sign figures on this page come from the binding ordinance text: Phoenix Zoning Ordinance, Section 705 — Signs. The historic preservation district rules come from Zoning Ordinance Chapter 8, Historic Preservation (§811 and §812), read 10 October 2026, of which a copy is kept. Measured on 21 August 2026: one reading returned the full section carrying every allowance and cap quoted here, and a second attempt twenty-five minutes later was refused with HTTP 403, so the host throttles automated reads and the twice-monthly check will not always reach it. We still cite it as the source of record because it is the binding text and it demonstrably carries the figures; the city permit-services page it replaces has returned nothing at all on eight consecutive automated runs and was application guidance rather than binding text. If the refusals persist, these figures go unchecked and need another path.

It also covers what happens after issue — written approval from department personnel is required “before any change, modification, alteration or other deviation from the terms and conditions of the sign permit and before any such change in the use of the sign as originally permitted can be made.” Changing what a permitted sign is used for is itself a step back to the counter.

Each item is reproduced with the exception or condition the ordinance attaches to it; the window-sign limit is taken from §705.D.5.

§705.B.3 lists signs “not permitted in the City of Phoenix, except as provided elsewhere in this section” — the carve-out is part of the rule, and one of the items carries the right-of-way projection allowance.

• Signs which occupy or project into public right-of-way. No sign shall occupy public property in any manner, nor extend across a property line bordering a street, highway, alley, lane, parkway, avenue, road, sidewalk or other right-of-way — dedicated in fee or by easement, used as right-of-way or not. The exception: wall signs may project a maximum of eighteen inches into such right-of-way, provided the bottom of the wall sign is at least eight feet above grade. (a)(1)
• Signs that interfere with traffic control or driver safety, in five listed ways: (1) by position, shape, color, format or illumination obstructing the view of, or liable to be confused with, an official traffic sign, signal or device or any other official sign; (2) displaying lights resembling the flashing lights customarily associated with danger or used by police, fire, ambulance and other emergency vehicles; (3) using, in a manner that may confuse motor vehicle operators, the words “stop,” “warning,” “danger,” “turn,” or similar words implying danger or a need to stop or manoeuvre; (4) creating in any other way an unsafe distraction for motor vehicle operations; (5) obstructing the view of drivers entering a public roadway from a parking area, service drive, alley or other thoroughfare. (c)
• Vehicle-mounted signs, except as provided elsewhere in the section or specifically exempted by other sections of the Code. Signs mounted upon, painted upon or otherwise erected on trucks, cars, boats, trailers and other motorized vehicles or equipment are regulated as ground signs, and a sign mounted on a trailer chassis — with or without wheels — is treated as a portable ground sign, which is prohibited. (d)
• Signs that interfere with visibility at street intersections or driveways. At all public street intersections no sign may be erected between the heights of three (3) feet and ten (10) feet, and nothing else may obstruct vision between those heights except a single post or column no more than twelve (12) inches across at its greatest cross-sectional dimension. The zone is the visibility triangle formed by the lot lines on the street side of the lot and a diagonal line joining points on those lot lines at the distances Table B-1 sets. (e)

  Table B-1 — Size of unobstructed sight triangle at corner lots

  Classification of intersecting public streets	Distance measured along each street (dimension "X")
  Local–Local	33'
  Local–Collector	33'
  Collector–Collector	33'
  Collector–Major	33'
  Major–Major	33'
  Major–Local	33' along the major street; 15' along the local street
  Any public street–driveway	33' along the major street; 15' along the local street; 10' perpendicular to the street

  Street classifications are as defined in the City of Phoenix Minimum Right-of-Way Standards Map.

Item (b) sets the clearance and thickness for projecting signs. §705.B.3(b) prohibits a projecting sign erected with the bottom of the sign closer than eight feet to ground grade level, and where the sign is of solid construction it caps the thickness measured between its principal faces at forty-eight inches.

Animation and illumination limits — §705.C

§705.C opens with “all on-premises signs in Phoenix must conform to the following regulations,” so these apply to the permit-exempt signs above as well.

• Animation. “No sign shall be animated or contain the optical illusion of sign movement,” except as may be allowed in the commercial land use designations defined in §705.D.1.a, subject to obtaining a use permit under §307. (C.1)
• Two things the ordinance says are not animation: time and temperature devices, and electronic message displays approved with a use permit under §307 and §705.C.13. (C.1)
• Indirect illumination. The source “shall be so oriented or shielded that it is not visible from any residential use or public thoroughfare.” (C.6.a)
• Incandescent direct illumination. It “shall not exceed eleven watts per bulb without a dimming device or sunscreen; provided, however, no single bulb shall exceed forty watts.” (C.6.b)
• Night curfew by wattage. Illumination “shall not be used from 11:00 p.m. until sunrise on directly illuminated signs where the total light sources on any face exceeds one hundred fifty watts.” (C.6.c)
• Sixty-foot setback from single-family. “In no event shall an illuminated sign be located closer than sixty feet to any single-family residential use or undeveloped property with a single-family residential zoning classification (RE-43 through R-2, P.A.D.-1 through 12) unless the sign does not face or is not oriented to the residential property or a use permit is obtained” — the ordinance’s section reference for that use permit is cut off in the copy on file, so this page names the use permit without a section number. (C.6.d)
• Flags and banners have only three routes. A flag of a political entity or religious institution that needs no permit under §705.B.2.b; one corporate flag per premises in the commercial land use designations, subject to a use permit; or where specifically allowed as part of a special sign district. Pennants, streamers and similar devices get no other route. (C.2)
• Combination signs. The thickness measured between the principal faces may not exceed sixty inches where the sign is of solid construction. (C.5)
• Light sources that are simply not permitted. No flashing, blinking or rotating lights; no metal halide exceeding seventy-five watts; no high or low pressure sodium bulbs — for permanent and temporary signs alike. Mercury vapour may never be used for direct or internal illumination. (C.6.e)
• Dark sky. All sign illumination must satisfy the Phoenix dark sky ordinance, §23-100 of the City Code. (C.6.f)
• Exposed neon is allowed. Exposed neon and similar tube illumination, and bare incandescent or fluorescent lights, are permitted as an integral part of a sign. (C.6.g)
• Signs on light poles. No sign or group of signs exceeding an aggregate four square feet may be erected on a light standard or pole unless the structure was designed for it, or it can be demonstrated that the structure is strong enough for the additional load. (C.7.d)
• Sound. No sign may emit sound intended to attract attention beyond the boundaries of its lot, or that creates a public nuisance. (C.8)
• A nearby billboard can eat your ground-sign allowance. An outdoor advertising sign on the site, or within two hundred feet of the property advertised, is included in that property's allowed ground sign area where it advertises that property exclusively. It is not included where it relates to multiple properties or businesses. (C.9)
• Maintenance is enforceable. Lettering, copy and painted surfaces must be free of chipping, peeling and fading detectable within three hundred feet; plastic and acrylic components free of cracks, holes and buckling; electrical signs in working order, with defective bulbs, tubes, neon segments, wiring and control devices promptly replaced. Where the City finds these standards unmet it gives notice of the specific defects and a reasonable time to correct, and failing to comply is a violation of §705 that necessitates total removal of the sign and sign structure. (C.10)
• Rotating signs are permitted only on obtaining a use permit under §307. (C.12)

Electronic message displays — §705.C.13

A changing-message sign is permitted in the commercial and industrial land use designations, and for nonresidential uses in residential districts, only on a use permit under §307 — and then only on these terms.

• How the copy may change. Only through an immediate transition that does not have the appearance of moving text or images. No flashing, intermittent or moving lights, no optical illusion of movement, and no part of the sign structure or cabinet may move or rotate. (a)
• Minimum eight seconds per message. The zoning administrator or the board of adjustment may lengthen that only where the sign is within one hundred feet in any direction of another electronic message display and traffic safety concerns are raised — in eight-second increments to a maximum of thirty-two seconds, or longer if the applicant requests and agrees. (b)
• Brightness is capped and metered. The sign must include photocell technology that varies the lighting intensity with ambient light, and the intensity may not exceed three hundred nits from dusk until dawn. (c)
• Night shutdown near homes. No illumination between 11:00 p.m. and sunrise where the sign is within one hundred fifty feet of single-family residential zoned property and visible from it. (d)
• Where it may go. Only on property adjacent to a freeway, major arterial, arterial or collector street as designated on the City of Phoenix street classification map, and spaced a minimum of one hundred feet from flashing warning signs — including those at school crosswalks, train crossings and fire stations. (g)
• Height near a traffic signal. On a ground sign within fifty feet of a traffic signal that alternately directs traffic to stop and proceed, the display's maximum height is eight feet, rising one foot for every twelve feet of additional setback from that signal, up to the district's ground-sign limit in §705.D. The distance is measured between the closest points of the ground sign and the signal pole, shown on a site plan or survey filed with the application. (h)
• Used as a wall sign. An electronic message display may be a wall sign, and may identify any use in a multi-tenant building rather than only the suite it sits on — but only where those uses are not also identified on a ground sign carrying an electronic message display. (e)
