Noise Pollution and Property Values

When it comes to a home’s value (and your sanity), noise pollution can be a major downer. But what is noise pollution exactly? Most people have different definitions of what noise pollution actually is—anything from sirens to a barking dog, or the noise of traffic on the street outside.

While outside noise isn’t totally escapable (even the prairie has ambient noise), home buyers will want to be on the lookout for excessive noise pollution, because it could affect a property’s value. After all, you don’t want to live in (or have to eventually unload) a place that requires a lifetime supply of earplugs.

First, let’s define what noise pollution actually means.Re

What is noise pollution?

In defining noise pollution, there are several variables in the mix.

“Noise pollution is basically any noise that you don’t like, but I guess we would define it as noise that most people generally don’t like,” says Brooklyn Law School Professor David Reiss, research director for the Center for Urban Business Entrepreneurship. “When governments regulate noise, however, it is usually based on how loud a noise is.”

For example, Reiss explains that according to A Guide to New York City’s Noise Code, in that city, “Noise that exceeds the ambient sound level by more than 10 decibels (dB) as measured from 15 feet from the source as measured from inside any property or on a public street is prohibited.”

Of course, the ambient sound level in NYC is considerably louder than in a rural area.

How to measure noise pollution near a home

Although decibels are used to measure the intensity of a sound, there are more accurate ways to identify noise pollution around a particular house. When it comes to getting ballpark figures for typical noise levels, Tom Davies, Co-Founder and Manager of the property buying company Accelerate Homes, suggests that most buyers figure out the day-night average sound level (Ldn) or the day-evening-night average sound level (Lden), which are measurements that can help assess the impact that road, rail, air, and general industry has on the local population. Either of these measurements give a potential buyer a much more accurate assessment of overall noise pollution near their home. To measure these levels, get a regular decibel meter, take hourly readings, and plug those numbers into this online noise calculator.

You can also check this interactive national transportation map created by the U.S. Bureau of Transportation Statistics to get a general idea of noise pollution levels created primarily by interstate highways and airports in your area. Just type in your address (or the address of any home you’re considering) and get a general reading. Red means loud—think vacuum cleaner (like 60dB-80 dB), and purple means even louder, like the constant sound of a garbage disposal (80 dB and up).

Identifying noise pollution culprits

It’s not always easy to figure out what’s making all the noise, but it is possible.

“While some of the main factors could be easily spotted—like the proximity of highways, stadiums, airports, train, and bus stations—other factors like specialized traffic (regular truck deliveries or rubbish removal), or the presence of neighbors with loud dogs, are far less likely to be spotted at first sight,” says Davies. The only way to get to the bottom of it is to talk to the neighbors.

Reiss also suggests taking it a step further.

“Visit at different times of the day. For example, if there is a bar across the street, drive by on a Saturday night,” he says. “Also, ask local government officials, like community board district managers, about noise complaints.” Basically, it’s up to you to do your due diligence on sound.

How noise pollution affects property prices

High noise levels don’t automatically correlate with lower prices, Reiss says. Some of the most expensive homes in New York City are located in midtown Manhattan, a busy area that’s home to the theater district, the tourist magnet Times Square, and many major corporate offices.

“But within a certain market, there will be those who value quietness and those who value being in the middle of the action,” he says.

To get a true reading on how noise pollution will affect the value of a property, “you would need to distinguish short-term noise—like a neighboring construction site—from permanent noise—like from a neighboring firehouse,” says Reiss.

Just a Dude Fixin’ Cars

Realtor.com quoted me in Neighbors Sue Man for Tinkering With Cars in His Own Garage. It opens,

Charles Williams loves working on cars, a hobby he’s continued even after losing his legs in 1993 in a freak construction accident. So in 2007, he poured $65,000 into building a nearly 2,000-square-foot four-car garage next to his house in Harbeson, DE. The place—which has vintage license plates covering the walls and lifts so he and his buddies can tinker to their heart’s content without lying on the concrete floor—is a car nut’s fantasy. At least, it was, until some of Williams’ neighbors—apparently offended by the sight, smell, and sounds of guys doing guy stuff—decided to sue Williams for repairing cars in his own garage.

In 2014, three of Williams’s neighbors—Margaret Foulke next door and John and Carol Kane, who live 800 feet down the road—filed a lawsuit against Williams saying that the garage was a noisy, stinky nuisance and must be torn down, according to The Cape Gazette. In June, a judge ruled in favor of Williams, explaining simply, “Mr. Williams has a not-uncommon hobby—working on cars—that he pursues with an uncommon vigor.”

Nonetheless, the neighbors plan to take their case up the chain to the Delaware Supreme Court.

Williams says he’s spent $30,000 defending himself from his accusers, who also claim he built the garage without permits and runs it as an illegal business. But Williams denies these allegations as well, saying he received the proper permission to build and has never accepted money in exchange for repairs. In fact, he has even fixed vehicles owned by the very people are demanding that he tear down his garage!

“I’ve fixed their lawnmowers, I’ve fixed their tractor, I’ve fixed their golf carts… I did everything for them, anything they asked, since that’s what neighbors do,” says Williams.

At first glance, the plaintiffs seem like candidates for a “worst neighbors” award. But we had to wonder: Is there anything to this case? Is it ever illegal for to tinker with  cars in your own garage?

While local laws vary by area, as a general rule, David Reiss, a professor of Law at Brooklyn University and editor of REFinBlog.com, thinks the neighbors are spinning their wheels.

“The facts sure don’t seem to be on their side, at least as this article portrays them,” says Reiss. Here’s a rundown of the neighbor’s complaints about the garage, and why Williams appears to be in the clear.

Noise complaints

“There are a lot of loud things in and near homes,” points out Reis. Compare a vacuum cleaner at 10 feet (70 decibels) to a lawnmower (as high as 90 decibels) to a train (100 decibels).

“Many localities have restrictions on the decibel level of noise that can come from a property, but those levels can be pretty darn high,” Reiss explains. “New York City, for instance, limits garbage trucks to 80 decibels from a distance of 35 feet when they’re not compacting. It limits music from commercial establishments to 42 decibels when measured from inside a neighbor’s home.”

In other words, the sound of a few motors running or rock music probably aren’t loud enough to write home about—or to sue over.

Noxious fumes and other nuisances

Sure, these neighbors could claim that the eau de motor oil emanating from William’s garage is a “nuisance.” It’s just that they would have to be deemed “unreasonable in the context of their residential neighborhood,” says Reiss.

“The neighbors could also argue that the increased traffic that resulted from this use was a nuisance too, but that also seems like a major stretch,” says Reiss.

Illegal activity

“The neighbors could claim that Williams is running a commercial establishment in a residential neighborhood, but it sounds from the article like the facts don’t support this claim,” says Reiss. So unless the neighbors catch a huge wad of cash passing hands, Williams is just a regular dude who digs cars.
