Requiring at least one checkbox selected within a group of checkboxes, same issue with text fields

I’m creating a form for requesting inspections. The user may request multiple types of inspections; however, specifying at least one of them must be required. I’m using checkboxes to specify the different types of inspections that may be requested. Is there a way to group all checkboxes as a single required field so at least one checkbox is selected when the user submits the form? I’d also like to accomplish this with text fields, where a single permit number must be specified; however, more than one permit number may be submitted. The form currently has different text fields for specifying the different types of permit numbers. Any and all recommendations will be greatly appreciated.
