How much does it actually cost to permit a retail store in Wilmington?
There is no single figure, and any site quoting one is rounding away the part that matters. Of the 14 records listed for a retail store in Wilmington, DE, 5 apply to every business of this type and 9 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 5 that always apply, 3 carry a flat fee, coming to $425.00. That is a floor, not a total. 6 of the 14 are charged as a range or a formula set by the issuing agency, and 1 has 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.
