Attack of the Killer Billboards

San Francisco has a maze of billboard rules that vary by neighborhood. Size restrictions vary, depending on location. For example: "In neighborhood commercial districts, general advertising signs cannot exceed 72 square feet or 12 feet in height. In the South of Market, one lot cannot have more than two signs exceeding 300 square feet. In Chinatown, signs are limited to one per lot, and they cannot be more than 72 square feet or 12 feet high." The city has shown little interest to police those billboards that don't have permits. Supervisor Mark Leno has started a campaign to regulate the billboards. Charges of political favoritism abound.
