How much does it actually cost to permit a restaurant in Wilmington?
There is no single figure, and any site quoting one is rounding away the part that matters. Of the 17 records listed for a restaurant in Wilmington, DE, 7 apply to every business of this type and 10 are conditional. Adding every fee on the page together would overstate what most operators pay, because it would include permits they never need.
Of the 7 that always apply, 4 carry a flat fee, coming to $575.00. That is a floor, not a total. 6 of the 17 are charged as a range or a formula set by the issuing agency, and 3 have no fee published at all. The ones particular to this business that vary:
Sign Permit (erection permit plus annual maintenance renewal): Two distinct charges under §41-65. First, an erection permit: $6.00 for each $1,000.00 of valuation or fraction thereof, based on the total valuation of all work and material involved to complete the sign, charged again on any alteration or relocation; an illuminated sign adds a separate flat $6.00 for the electric wiring and installation. Second, an annual renewal permit to maintain the sign: $10.00 for a sign not exceeding 50 square feet of face area plus $5.00 for each additional 50 square feet or fraction thereof; marquees, fixed awnings, canopies and similar fixed structures over public property are charged on the same $10.00-plus-$5.00 basis but measured by horizontal projected area; clocks, barberpoles and similar advertising devices are a flat $5.00; and no fee is ever less than a $5.00 minimum. Temporary signs are $10.00 up to 50 square feet plus $10.00 for each additional 50 square feet or fraction, with no permit required at all for a temporary sign of 25 square feet or less whose longest dimension is eight feet or less. Sign area is the product of the extreme vertical and extreme horizontal dimensions, measured from the building face or support on a projecting sign and between the outer limits of the letters where freestanding letters are used, and face area is counted on each face on which the sign is readable or has value as an advertisement.
The other 5 variable fees belong to permits that apply to every type of business here; their formulas are set out on the Wilmington permits page and the DE state page.

City of Wilmington Business License — Restaurants
$300.00 a year, stated identically in three City texts. City Code § 5-101(a), current on the City's codified ordinances, prices 'Restaurants' at $300.00; Ordinance #0288 (Ord. No. 23-014), effective July 1, 2023, set that figure, striking the previous $181.00, and introduces the same schedule with the words 'The following rates shall be annual fees imposed under this article, except as otherwise specifically provided'; and the City's own Application for Business License fee table ('FEE INCREASE EFFECTIVE 1/1/2024') prints $300.00 against license type code 2009, which requires a copy of Board of Health approval. Section 5-93 licenses restaurants within the entertainment/recreation classification, which 'includes places where food is prepared and sold for consumption on the premises.' Section 5-78(e) treats as a restaurant a retail establishment with 15 or more tables and chairs on the premises, table service and accessible public bathrooms, and provides that 'An establishment failing to comply with any one of the above referenced criteria shall have the designation of retail-edible' — the $250.00 Retailers Edible category listed for a coffee shop in Wilmington. Section 5-101(b) lets a small business with ten or fewer full-time employees that has existed for less than three years pay the fee imposed before the schedule's most recent amendment, on proof satisfactory to the Department of Finance.
