Condo Balcony
First: As long as you have exclusive use of your balcony, your association cannot say jack about placing a dish on the balcony.
Second: The Commission has previously ruled that when a dish is placed on a balcony it MAY overhand non-common elements, so long as the balcony is under the control of the unit owner.
In summary, any part of the common elements under the exclusive control of the unit owner, ie: driveway, balcony, garden, etc, can be used to install an OTA antenna and dishes are included in the definition.
NOTE: Your Board and / or Association can neither require advance notice for installation, nor cause you to file an installation diagram, nor cause you to use a specific bracket, nor cause you to pay any fee, no require any kind of pre-approval before you are allowed to install any DISH or other OTA receiving antenna. SO LONG AS YOUR DISH IS IN A COMMON AREA UNDER THE EXCLUSIVE CONTROL OF THE HOMEOWNER.
These rulings apply to both apartments, condos and townhouses.
