By USSignCode Editorial · Last updated October 11, 2026 · How we check this page

In eleven of the twelve cities here you can still get the permit afterward, at a higher price; Houston fines instead. Here is what each city’s own text charges, and whether that text is about signs or about permits in general.

QuestionShort answer
Can I still get a permit?In eleven of these twelve cities the extra charge is tied to getting the permit late; Houston sets a fine instead. Fort Worth and Phoenix charge their investigation fee whether or not a permit is then issued.
How much more will it cost?From an investigation fee equal to the permit fee (Fort Worth, Phoenix) to double fees (Atlanta, with the penalty portion capped at $1,000, Denver, Jacksonville, Sacramento, San Antonio), three times the fee in unincorporated Clark County, and nine times the issuance fee plus the original fee in San Francisco.
Can it be a fine instead?In Houston a sign without a permit is a misdemeanor: $300 to $500 for each violation, each day a separate offense.
What if the city already stopped the work?Chicago adds a stop work order penalty ($1,000+), and in most cases triples the building permit fee.

Cities not listed

For the other cities we cover, we found no official text we could tie to a sign put up without a permit, so this page says nothing about them. Where a rule is about permits in general, the “Whose rule” column says so; ask the permit office whether it applies to your sign.

Each answer is taken from the city page, which links the code text it was read from.
