Conformity of Improvements to Neighborhood

The improvements should conform to the neighborhood in terms of age, type, design, and materials used for their construction. If there is market resistance to a property because its improvements are not compatible with the neighborhood or with the requirements of the competitive market because of adequacy of plumbing, heating, or electrical services; design; quality; size; condition; or any other reason directly related to market demand, the appraiser must address the impact to the value and marketability of the subject property. However, the underwriter should be aware that many older neighborhoods have favorable heterogeneity in architectural styles, land use, and age of housing. For example, older neighborhoods are especially likely to have been developed through custom building. This variety may be a positive marketing factor.
