ROH §14-7.5Who pays for underground utility lines
Read the official text at honolulu.gov ↗This rule says who pays for utility lines when they are put underground. In special design districts, utility companies pay for lines in public streets, and property owners pay for work on their own land. Outside those districts, utility companies pay for overhead lines in public streets, the city and utility company split the extra cost of going underground, and property owners still pay for private property changes.
