Building Code Violations To Look Out For

Ducking Permits

You may think not applying for a building permit helps shave costs and sidesteps all the bureaucratic BS, and you'd be right—and wrong. Skipping permits means you won't have access to your local building inspector, somebody who knows all the codes and can ensure your project is in compliance. That translates to the utmost safety for you and your family, and avoids code violation stumbling blocks when it comes time to sell your house.

"By far the biggest mistake do-it-yourselfers make is not getting the right permits," says Rich Nolan, a structural engineer and owner of Nolan Engineering in Burt Hills, N.Y., a firm that specializes in home inspections. "You may think you can do without permits, but that can really come to haunt you in the end."

Improper Bathroom Venting

Got that new humidity-controlled venting fan all snugged up in the bathroom ceiling? Good job, but if your fan vents into an enclosed attic space, it's a code violation.

Dumping humid air into an enclosed attic can lead to mold growth and rotted wood. Codes say your fan should expel humid bathroom air to the outside via a 4-inch diameter vent pipe, typically the shortest route possible for maximum efficiency. A soffit vent is a good exit point.

Many Happy Handrail Returns

Whew! You got that new handrail on the stairs to the second-floor bedroom just in time for grandma's visit. But unless the ends of your wall-side handrail make a 90-degree turn and dead-end into the wall, you're violating code. Why? The open ends of a handrail can easily snag a purse strap or loose piece of clothing. Combine that goober with a set of stairs, and you've got a recipe for a hospital visit.

Bad Ledgering

Your accounting skills may be fine, but if your deck isn't properly attached to your house with a safe and secure ledger board, you could be putting your whole graduation party at risk. According to the North American Deck and Railing Association, some 40 million existing residential decks were built prior to 1990—before stricter codes for deck construction mandated safer techniques.

Ledgers are key points of deck failures. A ledger should be bolted or screwed directly to the house framing—not nailed—and must be protected with flashing to prevent moisture damage.

Wrong-Way Smoke Detection

The best protection you have in the event of a fire is a smoke detector. They're required on every floor of your house, inside every sleeping area, and outside every bedroom entry. Alarms on ceilings must be at least 4 inches away from walls, and alarms on walls must be 4 to 12 inches from the intersection of the wall and ceiling. For optimum performance, keep alarms at least 3 feet away from HVAC vents, ceiling fans, and lighting fixtures.

Smoke alarms in new construction must be hard wired and include battery backup, and multiple alarms must be wired together so that all alarms go off at the same time. If you're doing a renovation project on a house, you must update any battery-only alarms to meet the current requirements.
