This pamphlet describes the background of HUD's eight - volume Rehabilitation Guidelines published in 1980, their benefits for cities and States, and topics covered by individual volumes. HUD developed these voluntary guidelines to help jurisdictions overcome a serious impediment to rehabilitation: codes and the application of regulatory processes designed for new construction imposed on rehabilitation activities. Rehabbers of old buildings find it sometimes expensive, time consuming, or even impossible to comply with new construction requirements in building codes. Some cities with successful rehabilitation programs have overcome these problems by instructing their inspectors to ignore certain building code requirements in rehabilitation projects, although this encourages other violations of city ordinances and may create liability problems. The first volume, Guideline for Setting and Adopting Standards for Building Rehabilitation, describes methods for identifying regulatory problems and recommends ways to revise existing legislation. The second, Guideline for Approval of Building Rehabilitation, focuses on differences between regulating new construction and rehabilitation projects. The third, Statutory Guideline for Building Rehabilitation, contains enabling legislation that promotes rehabilitation through more effective regulation. The guideline for Managing Official Liability Associated with Building Rehabilitation considers code officials' liability. The final four volumes address the following topics; components of egress; electrical systems; drain, vent and waste systems; and fire ratings of building materials and assemblies no longer listed in current codes or references.
