Loma Linda, California, a community of 20,000 people, may be the first town in the country to require broadband infrastructure in new housing. This article from the May, 2005 issue of Broadband Properties (scroll down to get the PDF file) details the ordinance that requires builders to install structured Ethernet (broadband) cabling in every living space in new homes, as well as run fiber to the homes in the development, and to provide neighborhood colocation space for network equipment (what I call an NSAP, or Neighborhood Service Access Point).
This kind of approach future-proofs the community and reduces the cost of broadband access. Builders install the neighborhood infrastructure and turn it over to the town when the development is complete, just as they turn over other infrastructure like streets, sidewalks, water, and sewer. The article cites a study that shows homes with fiber to the home (FTTH) sell for $4,000 to $14,000 more than the same home without broadband access. So the builders easily recoup the additional cost, and the increased value of the home provides tax benefits to the town (which helps pay for maintenance).
