Full Breakdown

Before letting or renting any dwelling unit, Wilmington owners must hold a business license under section 5-34 and let the department of licenses and inspections inspect the unit for a limitation of occupancy notification setting the maximum legal occupancy. A unit can't be rented until that notification issues, and a copy must go to the tenant at signing. Skipping the license or registration triggers a civil fine.

Violations & Fines

Failing to obtain the required business license, failing to register a rental dwelling unit, or renting a unit before the occupancy notification issues carries a civil fine of $500.00 per rental dwelling unit, per Sec. 34-86(c).

Frequently Asked Questions

Can I rent out a unit in Wilmington without registering it first?

You're liable for a $500.00 civil fine per rental dwelling unit under Sec. 34-86(c), on top of needing the license and notification anyway.
