If you are a landlord who has section 8 tenants and need to evict them, you will need to comply with numerous federal and state laws which are so confusing, even lawyers often cannot determine exactly what they are. Generally speaking, you can often evict a section 8 tenant for “good cause” (defined in your separate section 8 contract) after 90 days of notice. You will need to give the housing authority the same notice and you will need to make certain the notice is perfect. The most common reason for problems in evictions is the notice. Everything flows from and through it. If notice is bad, you are finished and need to start over. In Sonoma County, you can contact the local PHA (Public Housing Authority) in Santa Rosa and ask them questions. You can also find other information here.
