A tenant with a handicap asks his or her landlord for permission to install grab bars in the bathroom at his or her own expense. It is necessary to reinforce the walls with blocking between studs in order to affix the grab bars. It is unlawful for the landlord to refuse to permit the tenant, at the tenant's own expense, from making the modifications necessary to add the grab bars. However, the landlord may condition permission for the modification on the tenant agreeing to restore the bathroom to the condition that existed before the modification, reasonable wear and tear excepted. It would be reasonable for the landlord to require the tenant to remove the grab bars at the end of the tenancy. The landlord may also reasonably require that the wall to which the grab bars are to be attached be repaired and restored to its original condition, reasonable wear and tear excepted. However, it would be unreasonable for the landlord to require the tenant to remove the blocking, since the reinforced walls will not interfere in any way with the landlord's or the next tenant's use and enjoyment of the premises and may be needed by some future tenant.
