Smoke Alarms

The idea behind smoke alarms is fairly simple. If you are alerted by the smoke before he flame reaches your location, you will have more time to escape.

Multiple smoke alarms that can signal each other can alert you even before the smoke reaches your location. These new alarms are ‘interconnected.’ This can be done either with an actual wire or with a dedicated RF (radio frequency) signal.

Many of the homes with fatal home fires were found to have smoke alarms with dead batteries. Either the batteries were simply to weak to operate the alarm or had been removed in anticipation of replacement and simply forgotten.

To resolve this problem newer smoke alarms are supplied with ten year batteries and can be hardwired to the homes electrical system.

Hardwiring and interconnection is a code requirement of new construction in most areas. This presents far more time to get your family safely away from the house in the event that becomes necessary.

A licensing requirement for Baltimore County rental properties requires hardwired and interconnected smoke alarms regardless of the age of the property. Since many of these properties will be retrofitted for smoke alarms the wiring requirement becomes much simpler by the use of ‘radio linked’ alarms.

Combination alarms that detect carbon monoxide (CO) gases as well as smoke are available to accommodate homes that require them. Interconnection provides the same advantage of time as do the smoke alarms.

Don’t become a statistic. Install a smoke alarm if your home does not already have one. Become familiar with how it works and how to test and service it.ymf-151

Building Codes

Building codes represent minimum safe standards of design and construction required by a local municipality. Differences in code from one location to another reflect the varying needs and demographics of each area.

As a home inspector my concern for building codes is not for their enforcement, but rather the safety standards they represent. As a home buyer you will want to insure that your family is protected by the most current safety standards.

Housing needs have changed over the years as technologies and materials have changed. In the post WWII building boom no one could have anticipated the vast array of electrical appliances we enjoy today. As a result houses built during those years, current in their time, no longer have a sufficient quantity or style of electrical outlets. Heating systems and insulation that was adequate when fuel was cheap are no longer satisfactory today. Building codes change to reflect the changing needs of modern homeowners.

Many of these systems are invisible to the average home-buyer. Investigating and calling out these disparities is what a good home inspection is all about. It provides a benchmark for comfortable and economical ownership.

No, we don’t enforce building codes, but you will want your family to benefit from current accepted safety standards and the local building codes provide just that reference.
