Full Breakdown
Chapter 19 creates a Residential Rental Property Registration System requiring landlords to register every rental unit and comply with the Department of Land Use's random and complaint-based inspection program. Under Section 19.04.002(C)(3)(d), a landlord who fails to respond to the Code Official within four hours of notice of an 'emergency condition', loss of heat, water, hot water, or electricity, and correct it within twenty-four hours faces a $500 civil penalty per affected unit, plus $500 per day for continuing violations and $1,000 for repeat offenses within twelve months. The chapter applies to unincorporated New Castle County and incorporated municipalities that contract in; Wilmington and Newark, which run their own housing codes, are not covered unless they opt in.
Violations & Fines
Failure to respond within four hours or correct within twenty-four triggers a $500 penalty per unit, $500 per day it continues, and $1,000 for repeat violations within a year.
