The way I read it an SAB can have opening hours and can have an address. Google suggests you should hide the address but it's not a rule.
To display the address, the business must be staffed during posted business hours and have permanent signage. This is a rule. Here is the link to the
TOS.
If your business either has a physical location that customers can visit, or travels to customers where they are, you can create a Business Profile on Google. To make sure your Business Profile won’t be suspended we require that you:
- Avoid prohibited content and behavior. These policies apply to all of your Business Profile content.
- Reflect your business accurately.
- Comply with the product guidelines in this article.
Use a precise, accurate address and/or service area to describe your business location. P.O. boxes or mailboxes located at remote locations aren't acceptable.
- Create your Business Profile for your actual, real-world location.
- Suite numbers, floors, building numbers, and so on may also be included. Only include information like cross-streets and nearby landmarks in regions where the official street address doesn’t accurately pinpoint the business's location.
- If you must specify a mailbox or suite number:
- Enter your physical address as "Address Line 1."
- Enter your mailbox or suite number as "Address Line 2."
- If your business rents a physical mailing address but doesn't operate out of that location, also known as a virtual office, that location isn't eligible for a Business Profile.
- Businesses can't list an office at a co-working space unless that office maintains clear signage, receives customers at the location during business hours, and is staffed during business hours by your business staff.
- Do not include information in address lines that doesn't pertain to your business’s physical location, like URLs or keywords.
- Do not create more than one page for each location of your business, either in a single account or multiple accounts.
- Individual practitioners and departments within businesses, universities, hospitals, and government buildings may have separate pages. For more info, go to specific guidelines about individual practitioners and departments.
- Businesses showing their address on Google should maintain permanent fixed signage of their business name at the address.
- If your address doesn't have a street number, or the system can't find it, you can pin your business's location directly on the map.
Service-area businesses
Service-area businesses, or businesses that serve customers at their locations, should have one profile for the central office or location with a designated service area.
Service-area businesses can't list a "virtual" office unless that office is staffed during business hours.
Some businesses, like auto repair shops that have a garage for repairs and offer roadside service, are hybrid service-area businesses. These businesses can show their storefront address and designate a service area on their Business Profile.
If you serve customers at your address and want to set a service area, your business location should be staffed by your team and able to receive customers during its stated hours.
Businesses associated with products or services that require the customer to be a certain minimum age, like alcohol, cannabis, or weapons, aren’t permitted as service-area businesses without a storefront.
Google determines how best to display your business address based on your business information and information from other sources.
Storefront versus service-area businesses
If your business doesn’t have a storefront with clear signage but travels to customers at their physical locations, you’re allowed one service-area Business Profile.
If you have different locations for your service business, with separate service areas and separate staff at each location, you’re allowed one profile for each location. The boundaries of your profile’s overall service area shouldn’t extend farther than about 2 hours of driving time from where your business is based. For some businesses, larger service areas may be appropriate.

If you’re a service-area business, you should hide your business address from customers.
- For example, if you’re a plumber and run your business from your residential address, clear the address from your Business Profile.
It's straightforward what Google requires in order to have a GBP and to show the address.
There is a difference between the rules and Google picking and choosing when to enforce the rules.
I did an audit on locksmiths in a major city.
180 GBPs
121 are in violation
17 are kiosks
11 kiosks can't be verified
146 GBPs between the violations and kiosks account for 82.7% of all listings
Locksmiths playing by the rules are 13%. That's some stiff competition to deal with, which is one of the reasons that the lead generation market thrives.
This is just one city; imagine what data I will have when I expand across the US? What data will I find when I look at other service industries?
The locksmith GBPs the OP has reported are in violation of Google's TOS and need to be removed.
