They can apply in the town they own the business in the same way they would apply in the town they live in.
There are two issues with this:
- A fair number of chiefs will refuse the application and tell the person to apply where they live.
- If their business changes the street address, they must apply all over again and pay the fee again. This was told to me by the FRB Director about the time that Pennypincher was filing for a resident LTC from her business address (she had moved to NH). So this is not just a "notify and done". Likewise, if they close the business, the local chief will expire the LTC.
If the business deals in large amounts of cash, many towns that normally restrict LTCs will issue non-restricted if they can prove that vulnerability.
