Charlotte Observer | 07/19/2007 | Residents: Sign enforcers go too far
Another Fred Pilot link to a story of a city behaving like an HOA:

Charlotte zoning enforcers are responding to neighborhood association requests to crack down on illegal portable signs, but residents of least one neighborhood are worried the city has gone too far. In the 12 months ended June 30, city inspectors investigated and resolved 7,385 zoning violations, more than twice the previous year. Some were related to portable signs, said code enforcement manager Walter Abernethy, but he could not specify an exact number. Among the portable signs that have drawn inspectors' scrutiny are yard signs for home improvement services that homeowners agree to post once work has been contracted. Six families clustered around Belvedere Avenue in Plaza-Midwood recently received warnings for architects' and landscapers' yard signs. Some residents said the warnings, which carry no fines, had vague inspector comments and the codes they violated are subject to interpretation. Without knowing exactly what law they broke, they said, they cannot prevent future citations that come with fines.
