FAQs: Basements

If you are installing any gas appliances, a first-gas inspection will also be required. Additionally, if you are required to move your plumbing ground works by breaking up the concrete slab, a plumbing ground works inspection will be required.

When scheduling an inspection of your basement, you must request a concealment inspection and then final inspection for each permit on the same day. Go to Finished Basements for more information.
