URM retrofit costs $120K-$4M but returns only $7.60 per $100 spent

Unreinforced masonry (URM) buildings, typically brick or stone structures built before 1940, are among the most earthquake-vulnerable building types. Cities like Seattle, Portland, and San Francisco have thousands of them, often housing small businesses, affordable housing, and cultural institutions in historic neighborhoods. Mandatory retrofit ordinances require building owners to strengthen these structures, but the cost ranges from $120,000 to over $4 million per building. A benefit-cost analysis found a public-private return of only $7.60 for every $100 spent on URM retrofits, making it nearly impossible for small building owners to justify the investment financially. Many URM building owners are small landlords or small business owners with limited cash reserves who cannot secure commercial loans for a project with negative financial returns. The result is a slow-motion crisis: buildings remain unretrofitted, tenants and customers remain at risk, and when a retrofit mandate finally forces action, the owner often sells the building to a developer who demolishes it and builds something new, destroying the affordable housing and small business space the neighborhood depended on. The problem persists because the buildings most in need of retrofit are precisely the ones with the least financial capacity to pay for it, and public grant programs are small relative to the scale of need.
