If you open your garage manually, you don’t need sensors. If you have an automatic garage door opener, sensors are required by law. The federal law UL 325 mandates that all residential garage door openers in the U.S. must include sensors. Designed to prevent accidents and reduce the risk of entrapment, the sensors should be able to reverse the motion of the garage door within two seconds of detecting an obstruction. The sensors are there to keep you, your family, and your belongings safe from a door that might otherwise come down too hard or too fast.

With the exception of small, lightweight torsion-spring garage doors, which can operate with one spring, most garage doors require two springs to work properly. Garage doors with extension springs always require two springs—if one extension spring is broken or otherwise failing, the garage door may open unevenly and could pose a hazard if the remaining spring fails.

It’s better to build a garage than buy and install a prefabricated one. You can save money by purchasing a prefabricated metal garage kit for between $4,000 and $11,000. However, this does not include the price of labor and permits, which can account for more than half of the project cost. Building a new garage over buying a prefab garage will add more value to your home and will last longer, so it’s more cost-effective over time to build a new garage.
