This is for a Chiropractor who will own a building where she will rent different suites to partners plus will have around 5-10 employees. This is located in Rockville, MD.
No there is not such Guide, because it will be a 300 page manual.
Your best bet is to pay a consultant who specialize in that area of business or at the very least find someone doing what you're doing and pay them to build you one.
You're going to want to set up a consultation with an attorney and identify a local HR/Payroll specialist. Most of them will offer free advice and can quickly provide the information you require. Best of luck!
There are two questions here:
1. How do I ensure appropriate permits for my building?
2. Where do I find lease agreements for renting my building?
You're best place to ensuring proper permitting is the City of Rockville, MD website: http://www.rockvillemd.gov/index.aspx?NID=1165
As for making sure your leasing agreement to your tenants is strong I would contact local attorneys who specialize is commercial properties. This is a much better than copy and pasting a template online. I admit they are difficult to interpret.
On a side note, be sure you are updating your leasing agreements every year to ensure new laws are taken into consideration.
Hope that helps!
