Door Alarms


Swimming Pool
The City Council has adopted local amendments to the National Electric Code (
Code of Ordinances Sec.98-233), including a requirement for door alarms on all exterior openings that provide access to a swimming pool, spa or hot tub. It specifies that:

1) Alarms must be installed on all doors with direct access to a pool, spa or hot tub area.

2) Alarms must sound within 7 seconds after the door is opened.

3) Alarms must capable of creating an audible notification that is at least 85 dBA at the source and must be audible throughout the house.

4) Alarms must be installed at least 54 inches above the floor and be mounted to the door/wall so that it cannot be easily removed.

5) Alarms must have a manual means to temporarily deactivate for a single opening.

6) In existing homes, alarms can be battery powered or connected to the permanent electrical wiring system. New homes constructed after July 1, 2016 must have alarms that are permanently connected to the building’s electrical wiring system.

7) In new homes constructed after July 1, 2016, exit doors which may be capable of providing access to a future swimming pool, hot-tub or spa must be pre-wired to the electrical system to accommodate the installation of a hardwired door alarm. This will require all new homes to have a junction box with an appropriately capped electrical power conductor to be installed at all rear exit doors (54 inches above the floor).

8) An additional “Pre-Plaster/Safety Inspection” is required for all pool/spa construction projects. In order to pass this inspection, all door alarms, permanent fencing, and self-closing gates must be installed and found to function properly.
