Do I need to provide functioning light bulbs for the term of the tenancy?
Usually tenants will replace their own light bulbs, but strictly speaking it is a landlords cost. Under Section 45 of the Residential Tenancies Act, it says the landlord is responsible and liable for costs incurred in maintaining the property and must replace any items that may expire over time. This includes light bulbs, ovens, tap washers, water filters and spa pool pumps.
Assess whether the light bulbs you have are easy to change. If so, provide your tenant with a dozen or so light bulbs for a year-long tenancy. This way you can avoid the extra cost of getting an electrician out to change them.
