you can't get a catering license downstairs in residential quarters.

Because:

1) There is a sonic boom in the hotel downstairs, which disturbs people.

2) Opening a restaurant downstairs does not meet the requirements of health and epidemic prevention.

3) There are hidden dangers of unsafe water, electricity and gas when opening a restaurant downstairs.

4) Opening a restaurant downstairs does not meet the requirements of sewage treatment.

5) Opening a restaurant downstairs does not meet the requirements of environmental protection and hygiene.

6) neighborhood committees and property and community owners will not agree.

Therefore, you can't apply for a catering license if you open a restaurant downstairs.
