This historical publication was produced by the NAHB Research Center for HUD to present a systematic methodology for estimating the cost impact of building code changes. The goal of the report is to assist decisionmakers in understanding the implications of proposed changes related to the cost of construction. The publication does not analyze code changes in relation to potential benefits, enforceability, or impact on the entire system of code administration. Steps in the author’s methodology include: providing basic information, developing a description of the code change, selecting representative types, depicting physical impact, estimating costs, and performing sensitivity analysis.

This report is part of the collection of scanned historical documents available to the public.
