RENOVATION OF PUBLIC-HOUSING - SUGGESTIONS FROM A SIMPLE-MODEL

This paper presents a simple model to contrast the benefit and cost of renovating public housing units against the benefit and cost of building new ones. Benefit is measured as the additional expected life created, and empirically-estimated survivor functions for housing are used to calculate maximum costs at which renovation is cost-effective relative to new construction. Actual renovation costs for an existing program are compared with calculated maximums. Results suggest that past renovation practice may not have been cost-effective relative to new construction. Possible changes in program guidelines are presented. The paper concludes with a discussion of policy implications.
