What Is It?
Illegal units are living spaces, usually apartments including separate kitchens and bathrooms, that were installed without a permit and may not meet the City’s zoning requirements and safety standards.
What It Isn’t
This section does not cover:
- rooming and boarding houses
- legal accessory dwelling units established by permit
- vacation rental units
Rules to Follow
- Owners must obtain a permit when adding a dwelling unit to a building.
- Owners must follow the rules for accessory dwelling units when adding a “mother-in-law” apartment to their own residence.
- If you're a property owner and receive a notice of violation for an illegal unit, you may be required to stop renting the unit if you can't obtain a permit.
You don't have to move until you receive a written notice to do so if you're a tenant in a unit that has been identified as an illegal unit. In many cases the owner will be able to legalize the unit.
