I would add that, depending on the nature of your business, you may be bound by regulations from other entities, be it underwriters, local/state/federal regulating agencies, etc. that may impose additional burdens on you and how information is kept in your office. In such cases, how you keep the information is more relevant than if your landlord has keys. Eg.: keeping documents in your office cabinets under lock, computers being password protected, screening of cleaning crews, etc.
