Ongoing repairs do not automatically prevent a rent increase, but the landlord must follow the rent-setting rules and give the required written notice. The amount and timing may depend on the tenancy, the applicable rent-control rules and whether the repairs affect the property’s condition or services. Do not withhold rent without advice; instead, keep records, report the repair in writing and consider asking for a temporary reduction or other agreement. If you dispute the increase or the standard of the accommodation, the RTB can assess the matter based on the facts, and you can check the current rules on the RTB or official government website.
