Summary
Self-storage and mini-warehouse facilities approved in Wilmington's C-2 commercial districts must aim all outdoor lighting onto the site and away from neighboring property, per zoning board conditional-use standards.
All lights shall be shielded to direct light onto the uses established and away from adjacent property, but may be of sufficient intensity to discourage vandalism and theft.

Full Breakdown
Under City Code § 48-193(d)(2)(l), any mini-warehouse or self-storage development seeking zoning board of adjustment approval in a C-2 secondary business district must shield every light fixture so it throws light onto the storage site itself and away from adjacent property lines. The ordinance explicitly allows fixtures to stay bright enough to discourage vandalism and theft, so operators can run high-intensity security lighting as long as it's aimed and shielded rather than spilling onto neighbors. The requirement sits alongside mandatory seven-foot security fencing and screening walls in the same subsection, and is one of the site-plan conditions the zoning board reviews before granting approval.
Violations & Fines
Zoning code violations are misdemeanors: $250-$1,000 for a first offense, up to $5,000 for repeat offenses, or up to a year in jail; the city can also seek an injunction under § 48-31.
