YES!!! We cannot emphasize enough the importance of properly located and maintained smoke detectors in the home. Without a doubt, they are the simplest, cheapest and most cost effective way to provide early warning against fire. Smoke detectors have been required by law since the early 1970's in all new homes built in the State of New Jersey.

The table below provides you with the requirements of the Construction Code regarding the number of and type of smoke detectors that are required based on the year the dwelling unit was built and that the dwelling unit must meet the new requirements of the Code.
