In 1995 Albuquerque commissioned a survey of parts of Nob Hill to record facts about buildings and to determine if particular buildings or districts might warrant nomination to the State Register of Cultural Properties. The State Register is New Mexico's official register of cultural properties considered worthy of preservation. A district largely mirroring the Monte Vista subdivision and the College View subdivision, both platted in 1926, was identified and was nominated. The district was listed in the NM Register of Cultural Places on September 18, 1998 in recognition of the large number of properties still displaying historic character illustrating the development of Albuquerque in the era between 1926 and WWII.
Subsequently, Albuquerque commissioned a nomination of the district to the National Register of Historic Places. This is the nation's official list of cultural resources worthy of preservation. Properties listed in the Register include districts, sites, buildings, structures, and objects that are significant in American history, architecture, archeology, engineering, and culture. The National Register is administered by the National Park Service.
On August 3, 2001 the District was listed in the National Register of Historic Places. The nomination can be downloaded from this page. Most of the 859 buildings in the district are houses and are not separately registered. Rather, in the survey, it was determined that 702 of them contribute to the significance of the district. You can read more about contributing properties and even determine if a particular property of interest is contributing by consulting pages 11 through 32 of the nomination. Pages 33 through 37 list buildings which, due to modifications, were considered by the surveyors to no longer contribute to the district's significance. Some of these properties could potentially be brought back to the point where they again contribute.
Page 77 shows a detailed map of the district's boundaries. A less detailed view of its boundaries appears on this site.
Listing in these registers does not restrict the use or modification of properties. However, since listing indicates that a property is worthy of preservation, it often stimulates owners to consider carefully how remodeling or changes may impact on the contribution their property makes to a district and to the record of development of their community.
New Mexico offers NM income tax credits in the amount of 50% of the cost of approved rehabilitation of contributing properties. Approved projects have included new roofing, stucco, modernizing electrical and plumbing systems, refinishing wood floors, and replacing heating and cooling systems. Work must be approved before it is initiated.
