To do this:

1. Go to the Settings > Company/department
2. Using the gear icon, click the Edit button next to the selected department/company.
3. Check the Restrict warehouses box.
4. Choose the warehouses to which you want the selected department/company to have access.
5. Click the Save button

To similarly limit the visibility of products or customers, follow the instructions described in the post Limiting Product Visibility or How to Limit Customer Visibility.
