Google My Business for service business that doesn't have an office

I want to start a cleaning business but renting local office space would be inefficient because I would be the only one working the business and I can manage everything from my phone and laptop. I think organic Google traffic would be critical for exposure so I want to get on Google My Business but I know they don't allow PO boxes and for my type of business, using my home address isn't best practices.

What are my options?
