Washington DC sign permit at a glance
| Question | Short answer |
|---|---|
| Do I need a permit? | Yes for any sign larger than 1 sq ft, unless it is on the exempt list: changeable copy on an existing frame, signs entirely inside a building, window signs covering no more than 20% of the window in Commercial and PDR districts, small unlit signs on the lot, and real estate signs of 6 sq ft or less (Appendix N §N101.3, §N101.3.5). Signs in areas reviewed by the Commission of Fine Arts, on historic property or in a Residential District need one regardless. Other cities compared. |
| How big can my wall sign be? | Up to 2 sq ft for each foot of width of the front of the building that your business occupies, kept within 20 ft of the sidewalk on the first floor (§N101.10.1, §N101.10.2). A 20 ft storefront works out to up to 40 sq ft. Other cities compared. |
| What does it cost? | $65 for a new sign up to 25 sq ft, $130 for 25 to 100 sq ft, and $130 plus $2 for each sq ft over 100. The fee schedule also says the Director charges an extra 10% on the total cost of each permit (12-M DCMR §101.1(a), §100.2) (fee table). Other cities compared. |
| How long does it take? | We found no review time for a sign permit in Appendix N or the fee schedule (timing). Other cities compared. |
| Total sign area on my building? | It depends on the building. A one-story building and a first-floor store use the 2 sq ft per foot rule; upper floors use a table (up to 40 sq ft where the wall above 20 ft is 1,600 sq ft or less); a building with one occupant is capped at 100 sq ft per street frontage if the wall is 4,000 sq ft or less (§N101.10). |
| Sidewalk A-frame sign? | Appendix N has no A-frame rule. It bars any structure used as a sign from a sidewalk or other public space unless the code official specifically approves it (§N101.7.8) (sidewalk rules). Other cities compared. |
| Blade or projecting sign? | Allowed in Commercial and PDR districts on brackets, projecting no more than 42 in. beyond the building line, with at least 8 ft of clearance above the sidewalk and no part closer than 18 in. to the curb lane (§N101.7.1, §N101.7.1.1). Other cities compared. |
| Grand opening banner? | A banner for advertising needs a permit, may extend no more than 42 in. over public space, and must hang at least 14 ft above public parking, a sidewalk or a roadway (§N101.7.5) (banners). Other cities compared. |
| Digital or LED sign? | A sign that shows moving, animated or periodically changing images or text counts as a revolving sign: Commercial and PDR districts only, up to 40 sq ft a face and 3 ft in its longest dimension, never on a roof, and the Department of Transportation must approve the color and electrical features (§N101.7.11). Other cities compared. |
| Already installed without a permit? | Appendix N points to fines under the 1931 Act it cites and civil fines under the Civil Infractions Act; we found no dollar amount in the text we read (§N101.15.3) (what we could not confirm). Other cities compared. |
Size limits Checker Fees How to apply Timing Sidewalk signs Banners and other types What we could not confirm FAQ
Appendix N splits the District in two. In Residential and Special Purpose Districts a sign needs a permit and the exemptions do not apply (§N101.9.1). Everywhere else the total sign area on a building, lot or parcel is limited by the type of building and the width of the frontage the business occupies (§N101.10). Work out which building type you are, then the frontage, then the fee.
Washington DC sign limits by building type (Appendix N §N101.10)
These limits apply in any district other than Residential or Special Purpose Districts. They count every sign subject to Appendix N on the building, lot or parcel; signs on the exempt list do not count (§N101.10.7).
| Building or case | Total sign area allowed | Section |
|---|---|---|
| One-story building | 2 sq ft for each foot of width of the front of the building occupied by the business, placed within that part of the front. Roof signs: 100 sq ft facing any one street frontage at most | §N101.10.1 |
| First-floor store in a multi-story building | The same 2 sq ft per foot, with the signs kept within 20 ft above the sidewalk | §N101.10.2 |
| Above the 20 ft line, wall up to 1,600 sq ft | 40 sq ft per street frontage | Table N101.10.3 |
| Above the 20 ft line, wall 1,600 to 4,000 sq ft | 1/40 of the wall area above 20 ft | Table N101.10.3 |
| Above the 20 ft line, wall over 4,000 sq ft | 100 sq ft for roof signs, or 1/40 of the wall area above 20 ft for signs below the roof | Table N101.10.3 |
| Building with one occupant, wall up to 4,000 sq ft | 100 sq ft per street frontage | Table N101.10.4 |
| Building with one occupant, wall over 4,000 sq ft | 1/40 of the wall area, of which not more than 100 sq ft above the roof | Table N101.10.4 |
| Unimproved lot, or lot with a small office | 2 sq ft per foot of street frontage, 150 sq ft per frontage at most, and no more than the one-story limit | §N101.10.5 |
| Parking rate sign (where 24 DCMR §612 requires one) | Up to 20 sq ft more, on top of the areas above | §N101.10.6 |
| Area reviewed under the Shipstead-Luce Act or the Old Georgetown Act | All signs for one business: 25 sq ft per street frontage at most; single-faced signs, at most two colors; copy limited to the name or address | §N101.4.1.4, §N101.4.2.4 |
Source: DCMR Building Code Supplement of 2017, Appendix N, Signs, section N101; read 24 October 2026. The Appendix says it adopts the 2013 District of Columbia Building Code Appendix N without amendment; the rule text we read took effect 28 March 2025.
Wall sign size is not a share of the wall on a one-story building. It is a flat 2 sq ft per foot of the frontage your business occupies, so the width of your own storefront decides it. The application has to state the width of the premises, or the width and height of the building, so the reviewer can work out the allowed area (§N101.3.2). Wall signs over 40 sq ft that are flat against the wall must be incombustible (§N101.11.8.1).
Check your sign against the limit
This applies §N101.10.1, §N101.10.2, §N101.4 and the 12-M fee schedule to a first-floor wall sign on a one-story building or a first-floor store. It does not see Residential or Special Purpose Districts, historic property or upper-floor signs.
Calculated from Appendix N §N101.10 and 12-M DCMR §101.1, read 24 October 2026. The extra 10% from §100.2 is shown separately. Electrical permit fees for a lit sign are not included.
How much does a Washington DC sign permit cost?
Fees are in Chapter 12-M of the DCMR, the Permits Division schedule of fees. Section 101.1(a) lists the sign line under building structures and equipment; Section 100.2 adds a technology charge to every permit.
| Fee | Amount | Section |
|---|---|---|
| New sign, up to 25 sq ft | $65 | 12-M §101.1(a) |
| New sign, 25 to 100 sq ft | $130 | 12-M §101.1(a) |
| New sign, more than 100 sq ft | $130 plus $2 for each sq ft over 100 | 12-M §101.1(a) |
| Billboard repair | $33 each | 12-M §101.1(a) |
| Special sign artwork change | $500 each | 12-M §101.1(a) |
| Electrical discharge sign (separate electrical permit) | $26 up to 500 VA, then $20 for each added 500 VA or fraction | 12-M §101.1(d), Group 3 |
| Technology charge on each permit | An additional 10% of the total cost of the permit | 12-M §100.2 |
- Example, a 24 sq ft wall sign: $65, or $71.50 with the 10% charge. A 40 sq ft sign: $130, or $143. A 150 sq ft sign: $130 + $2 × 50 = $230, or $253. These are our arithmetic from the schedule, and they assume the 10% applies to the sign permit fee.
- A lit sign needs a second permit. Appendix N requires a separate electrical installation permit for any sign with lighting or electrical features (§N101.3.4). The electrical fee depends on the wiring; the schedule prices an electrical discharge sign at $26 up to 500 VA.
- Special permits: a sign that does not conform may get a special permit if the code official finds the case unusual; the code official can attach conditions and a removal date (§N101.6.6).

What the schedule does not settle
Section 100.2 says the Director charges the extra 10% on "the total cost of each permit issued, or document furnished" under the chapter. It does not say whether that includes a sign permit specifically, though a sign permit is issued under the chapter, so we show the fee with and without it. We did not find a filing deposit, plan review fee or zoning fee for a sign alone; 12-M prices a deposit for new construction and alterations only. The fee text is dated 2018, so ask the permit office for the current figures before you budget.
How to apply for a Washington DC sign permit — 5 steps
Steps from Appendix N §N101.3, §N101.4, §N101.5 and §N101.15, read 24 October 2026. We did not find a sign-specific application checklist or online portal page on dcregs.dc.gov.
How long it takes
We found no review time for a sign permit. Appendix N gives none, and the fee schedule is a list of amounts. Ask the permit office for its current turnaround before you book an installer.
Source: Appendix N §N101.3 and §N101.6, read 24 October 2026. We found no permit expiry period for signs in the text we read, so we do not list Washington, DC in our expiry comparison.

Sidewalk signs and projecting signs
Appendix N does not mention A-frame or sandwich-board signs. What it does say about signs on the public sidewalk is strict.
- Public space: no structure or standard used as a sign, bulletin or advertisement of any sort may be placed or left on any street, alley, footway, sidewalk, parking or other public space unless the code official specifically approves it (§N101.7.8).
- Carried signs: no advertising sign or banner may be carried or transported on or over public space. Signs on vehicles that advertise the owner's own business are excepted (§N101.7.9).
- Projecting signs: allowed in Commercial and PDR districts on iron or steel brackets, stayed securely. They may project no more than 42 in. beyond the building line, must clear a sidewalk by at least 8 ft and a driveway by at least 15 ft, and no part may extend over public space closer than 18 in. to the curb lane (§N101.7.1, §N101.7.1.1).
- Awnings: one horizontal line of letters, each no more than 12 in. tall, on the vertical face of a valance or on a canopy, marquee, portico or awning, giving only the street number and the occupant's or trade name (§N101.7.4).
Whether an A-frame can be approved under §N101.7.8, and on what terms, is not stated. Sidewalk and public space use is also handled outside the Building Code. Ask the permit office before you put one out.

Banners, electronic signs and other types — 4 items
- Banners and flags used for advertising need a permit and may not extend more than 42 in. over public space or hang less than 14 ft above public parking, a sidewalk or a roadway (§N101.7.5).
- Revolving and changing-image signs: a revolving sign includes one that displays 3-D, moving, animated or periodically changing images or text. They are allowed in Commercial and PDR districts on the owner's land, not past the building line, and not on roofs. At most 5 revolutions a minute, 40 sq ft a face, 3 ft in the longest dimension, at least 8 ft off the ground and 20 ft tall overall; lights may not be exposed (§N101.7.11).
- Roof signs: not above the height limit set by the Zoning Regulations; limited to 100 sq ft facing any one street frontage on a one-story building (§N101.7.2, §N101.10.1).

What we could not confirm
- Review time. We found no published review time for a sign permit.
- Penalty amount. §N101.15.3 refers to fines under a 1931 federal act and civil fines under the Civil Infractions Act of 1985, with no dollar figure in the Appendix. We did not look up the fine schedule.
- The 10% charge. §100.2 reads as applying to every permit under the chapter; the text does not name signs.
- Current fees. The fee text on dcregs.dc.gov was last amended in September 2018. A later fee notice could change it; we did not search the D.C. Register for one.
- Zoning overlays. Appendix N refers to the Zoning Regulations for district definitions and roof height. We did not read them, so a zoning or overlay rule may be stricter than the figures above.
