Philadelphia sizes your wall sign from your storefront frontage — 1 to 10 square feet per foot depending on your zoning district (Table 14-904-1). Go over and your permit gets rejected. Enter your frontage and get a clear read before you build.
This checks on-premise wall signs in Philadelphia commercial/manufacturing zones. Off-site signs, billboards, and supergraphics are not covered. Digital/LED displays need separate review.

How Philadelphia sizes your sign
Philadelphia keeps it simple: under §14-904, your accessory wall sign is sized per linear foot of building frontage at a rate set by your district in Table 14-904-1 — 1 sq ft per foot in CMX-1, 3 in CMX-2/2.5, 6 in CMX-3, 2 in CMX-4/5. Freestanding signs follow their own height rules.
The catch is the special areas: Center City, Market Street East, and the Parkway buffer have their own rules and Art Commission review that override this formula. This tool applies the citywide §14-904 rule and flags when you should check with a pro.
How to apply for a Philadelphia sign permit
Most Philadelphia signs need two permits, and whether you qualify for the EZ Standard decides how much paperwork the second one takes.
1. Compute the §14-904 allowance
2 sq ft for every linear foot of ground-floor street frontage.
2. Check the special areas first
Center City, Market Street East, and the Parkway buffer have their own rules and Art Commission review that override the citywide formula. Historic properties need Historical Commission sign-off before L&I will even accept the application.
3. See whether you meet the EZ Standard for Sign Installation
Signs meeting it skip the plans and the filing fee, which is the difference between a routine filing and a plan review.
4. File both permits through eCLIPSE
A zoning permit and a building permit, filed with L&I.

Questions owners ask
What counts as my frontage?
The width of your ground-floor storefront along the street. Your wall-sign allowance is that number × the rate for your district in Table 14-904-1 (1 to 10 sq ft per foot).
Does my zoning change the number?
For commercial and manufacturing zones (C1, C2, C4, CM, M1, etc.) the wall-sign formula is the same. Residential zones and specific-plan areas have different rules — if your address is in one, we'll tell you and route you to a pro.
Digital / LED sign?
Digital displays face separate restrictions (Phila. Code 14-904.4) and many areas restrict or ban them. This screen covers static and illuminated wall signs; a digital sign needs its own review.
Is this an official ruling?
No. It's a first-pass risk filter on the public Phila. Zoning Code formula, not a permit and not legal advice. Final dimensions are confirmed by a licensed Philadelphia sign professional and Philadelphia L&I.
Cost, timeline & temporary banners
What does a Philadelphia sign permit cost?
Most signs need two permits: a zoning permit and a building permit. The zoning permit fee differs by sign class — accessory (advertising your own on-site business) is charged at a lower rate than non-accessory (advertising something elsewhere) — and the building permit adds a filing fee when plans are required (credited toward the final fee). Signs that meet the city's EZ Standard for Sign Installation skip the plans and the filing fee. Optional accelerated review costs extra.
How long does approval take?
This page gives no number: the source registered for it is the Philadelphia Zoning Code, which sets rules rather than review times, and we hold no L&I-published service level for sign permits. L&I does offer a paid accelerated review and an EZ Standard path, and applications without plans are often processed while you wait — ask L&I what each currently runs. Center City signs almost always need separate Art Commission approval, and historic properties need Historical Commission sign-off before L&I will even accept the application; both are extra approvals on meeting calendars.
Can I hang a "Grand Opening" banner first?
A banner needs a permit, and banners spanning a street or the public right-of-way go through the Special Events office, not just L&I.

Sources and official references:Philadelphia Code — Title 14 Zoning, §14-904 Accessory Sign Controls, district table and §14-903 When a Permit is Required. Measured on 21 September 2026: both sections read as text through our collector. The district table carries the per-linear-foot wall-sign allowance quoted here, §14-903 carries the temporary-sign sizes that need no zoning permit, and §14-904 carries the window-sign share. The chapter cover node returns a bot-check wall instead of text, so we cite the sections that read. A second-floor allowance this page used to quote is not in either section and has been removed.
