A paper street or paper road (also known as an Unformed legal road) is a street or road that appears on maps but has not been built.[1] Paper streets generally occur when city planners or subdivision developers lay out and dedicate streets that are never built.[2] [3] Commercial street maps based only on official subdivision and land records may show streets which are legally public rights of way though usually undriveable.Paper roads may exist only on paper, never having been developed, but they have a legal existence and have the same legal status as a formed road.[4] They are especially common in New Zealand, where they were created primarily for future access in rural areas (though in some cases, their layout was determined without checking whether the topography was acceptable for a road). Some districts are reputed to have as many paper roads as actual, formed roads.[5] An estimated 56000km (35,000miles) of paper road exists in New Zealand.[6] Controversies sometimes arise about ownership or use of paper roads.[4] Property owners may feel that an abutting undeveloped paper road is part of their property, but other property owners may have rights to access via that road, access which could be developed in the future if the need arises. The presence of a paper road can affect property valuation since there may be required building setbacks from the road, which might limit development opportunities.Paper streets (and, by extension, paper towns) may be deliberately included in published maps as trap streets, forming a copyright trap.A play on the phrase is found in Chuck Palahniuk's novel Fight Club, as well as the film based on that book, where the protagonist lives in a house on "Paper street". Paper towns play a large role in John Green's novel Paper Towns.
