About each permit

Building Permit

Who may pull the permit depends on job valuation: the owner/authorized agent alone for $10,000 or less; a City of Wilmington Licensed General Contractor for $10,001-$25,000; and a City-licensed General Contractor with plans sealed by a licensed architect or professional engineer above $25,000. All contractors and subcontractors listed on the application must hold a City of Wilmington Business License (listed separately for this jurisdiction). A separate Fire Protection Plan Review fee (listed elsewhere for this jurisdiction) applies on top of this permit for most commercial projects. This is the same $12.00/$20.00-per-trade formula the City's own 2016 Development Review guide showed, unchanged for this component even as the Certificate of Occupancy and Fire Protection Plan Review fees have since been updated (recorded separately below).

Zoning Certificate (Written Zoning Verification)

This $25.00 figure comes from the City's own 2016 Development Review Process guide, which states that for this fee 'an applicant may obtain a written certification from L&I that states the zoning designation for the parcel, whether the proposed use is allowable under that zoning designation and a list of any outstanding violations.' No current Land Use & Planning document cited here restates the figure, so it is given with its 2016 source date; confirm the current amount with the Zoning Manager. A verbal zoning determination remains available free of charge from the Zoning Manager without this written certification.

Zoning Board of Adjustment Variance Application

Confirmed from the City's own current Zoning Board of Adjustment Application, dated 6/24/2025 and published by the Department of Land Use and Planning, which prints the two rates directly under 'Application Fees.' An undated earlier version of the form circulating on a non-City site shows $250.00 commercial and $100.00 residential; the 2025 form served from the City's own domain is the newer document and its figures are the ones given here. The application also requires a notarized affidavit certifying the applicant is not delinquent on city property taxes, water and sewer billing, vacant property fees, instant housing violation tickets or property maintenance fees for the subject parcel, and the Board may in its discretion refund part or all of the fee where an interpretation appeal succeeds, while variance fees are not returnable regardless of outcome. The Board is a three-member quasi-judicial body drawn from City staff (Law, Public Works, and Real Estate and Housing) meeting on the second and fourth Wednesday of the month; applicants should anticipate four to six weeks from application to hearing.

Certificate of Occupancy

Historically also referred to as a 'Limitation of Occupancy Notification' (LON) in the City's own older billing terminology, per its current bill-search portal. A separate $50.00 Certificate of Compliance fee and a $50.00 re-inspection fee for a final Certificate of Occupancy also appear on the same current fee schedule. Every one of the ten industries this site tracks falls in the $100.00 commercial band, not the $75.00 residential rate.
