Caveat emptor
Caveat emptor is Latin for “Let the buyer beware”. Generally Caveat emptor was the property law doctrine that controlled the sale of real property after the date of closing. In many states, including Texas commercial leases are not covered under consumer protection laws that normally safeguard tenant rights. It is assumed that commercial leases are contracts between knowledgeable business people, and therefore less government regulation is needed than in residential leases. Landlord/Tenant law under the Property Code focuses almost exclusively on extending rights and remedies to residential lessors and lessees.
Commercial tenants are basically allowed to contract for anything legal, and are not bound by a majority of the terms set forth in the property code relating to landlord/tenant issues.
