What it is
The Certificate of Occupancy (COO) is the document from PP&D that says your building is legally inhabitable. It's issued automatically once all finals pass and the permit closes out.
How to retrieve it
- Shows up in your DevHub permit record after finals pass
- Usually emailed to the permit applicant
- Print and file with the project record
Why it matters
- Legal occupancy. Living in or renting an uninspected building violates the building permit.
- Insurance. Most homeowner's policies condition coverage on legal occupancy.
- Refinance / sale. Lenders and buyers will ask for it.
Temporary Certificate of Occupancy (TCO)
If you need to occupy before some non-critical items are done (landscape work, decorative trim), PP&D can issue a TCO with an expiration date for the remaining work. Useful but not always granted — ask early.
