Does the address for a non-immigrant O-A visa application in Thailand need to be permanent, or can it be temporary, such as a hotel address?

For the non-immigrant O-A visa application, the address provided does not need to be permanent for the entire twelve months. You can use a temporary address, such as a hotel, especially while searching for long-term accommodation. However, it is crucial that the landlord or hotel manager reports your stay to the local Immigration Office within 24 hours.
