Accessory structure building permit
You need a building permit if you are building a structure that is separate from your house, like:
- Garages and carports (detached and attached)
- Detached buildings, like a home office or workshop
- Storage buildings
- Large play structures
Some accessory structures don’t need permits, like sheds or playhouses. To be exempt from permits, they need to be:
- 1-story
- Less than 7 feet in height
- Detached
- Less than 120 square feet
If your structure has a cooking and sleeping area, you may need an accessory dwelling unit permit instead.
All exterior modifications require design review before you can get a building permit.
