When a tenant files an appeal or complaint about housing in Finland, assembling the correct attachments is often decisive. Acceptable attachments include photos, copies of repair requests, rent payment receipts and notes from condition or move-in inspections. Well-organized and timestamped evidence helps clarify the claim and speeds up processing. This guide explains which attachments are commonly needed, how to submit them and what deadlines to expect, and gives practical tips from a tenant perspective. The guidance is based on Finnish housing law[1] and administrative practice. If the matter cannot be resolved by negotiation, the claim may proceed to authorities or the courts[2], where attachments are crucial.
