It's illegal in Oregon for a landlord to rent a non-habitable dwelling. A non-habitable dwelling is dangerous to the health and safety of the occupants. Many tenants, especially children, end up in the hospital. If you live in moldville, leadville, carbon monoxideville, or in any other dangerous situation, and your landlord has refused your requests for repair, Oregon Law allows you to withhold rent. You have rights, but they come with legal duties. See an attorney to avoid mistakes.
