An Obstruction of Passageways Clause is a contract provision that outlines the responsibility of a tenant or landlord to keep passageways in the building clear and free from obstruction. This clause typically applies to common areas such as hallways, stairwells, and elevators. Obstruction of Passageways Clauses may require tenants to not store items in public areas, to keep passageways free from debris and clutter, and to keep hazardous materials away from the common areas. It may also prohibit the tenant from blocking or obstructing access to the passageways, or from engaging in activities that could cause a nuisance to other tenants. There are two types of Obstruction of Passageways Clause: the standard clause and the tenant-specific clause. A standard clause is usually included in the lease and applies to all tenants in the building. A tenant-specific clause is tailored to the individual tenant and may include additional restrictions or requirements.
