Most of your protections will be found not in the statutes, but in your lease. A common commercial lease gives the tenant the inside of a box, with the landlord responsible for the outside structure and common areas. A typical commercial lease also permits the landlord to pass along the cost of significant repairs or maintenance (new parking lot lights, repaving, new roof, etc.) to the tenant.
You can look for a law that says "The landlord must provide a new lease not less than X days before the current lease expires" or "A commercial landlord can charge no more than $Y per square foot" from now until the end of time - you won't find any such laws.
