Is a Tenant Obligated to Build a Safety Railing?

This source-based Torah study examines the question: Does the Torah’s obligation to build a protective railing fall on a tenant, and if so, at what level of obligation? A rented home raises a practical question about who carries responsibility for a required safety railing: owner, tenant, or both in different ways. It traces the issue through the parasha and the classical discussion without turning the material into an individualized ruling. The canonical review status is preserved for any practical, halakhic, ethical or theological claims.
