Important terms to know that deal with the parts of the condominium complex that are outside your unit are "common elements" or "limited common elements". "Limited common elements" are things like balconies and patios, that are used only by the owners and tenants of a single unit. "Common elements" are used by all, such as the parking lots, playground, and pool.
Balconies and patios are “limited common elements”. “Limited common elements” are structurally part of the common building, but are used by only an individual unit owner. It is your responsibility to maintain them in a neat and clean condition. You may not store indoor furniture, bicycles, or other inappropriate items on balconies. Outdoor furnishings such as patio tables and chairs are permitted.
Keys
The Bylaws require that each owner supply the Association with a working set of keys for emergency access and to perform other necessary duties. The keys are not a lock-out service, however, if you have provided the office with a key, the on-site manager can give you access to your unit during office hours. If your front and rear doors are keyed differently, you may want to provide both keys to the office in case an emergency blocks one door.
Mailbox keys are solely the responsibility of the Unit Owner. Neither the Association nor the Postal Service has a key for your individual mailbox. If your key is lost, the safest recourse is to replace the mailbox lock using the services of a locksmith.
