Full Breakdown
Tenants who report a problem, no heat, no water, unsafe wiring, trigger a complaint-based inspection under County Code Sec. 19.03.002.C: "the County shall have the right to inspect all rental units on a complaint basis." Before entering, the Department of Land Use must give the landlord and tenant 48 hours' written notice; if the tenant withholds consent or the landlord blocks entry, the Department can seek an administrative search warrant in court. The rule reaches unincorporated New Castle County and any incorporated municipality that has signed a participation agreement (Sec. 19.01.002); Wilmington and Newark run their own separate municipal codes and are not covered by this chapter.
