CRANBERRY TWP — Houses here are a hot commodity.

“Anything under $300,000 really sells fast, like immediately,” said real estate agent Georgie Smigel of Coldwell Banker.

The more expensive houses go quickly too. Smigel said she has seen houses priced at more than $500,000 in Cranberry sell in less than a day.

As home builders continue to pick the township for their projects, Realtors and township officials say there still is a strong demand to match the supply.

“It’s definitely a good market right now. A lot of things go pretty quickly,” said real estate agent Nancy Kaclik of Century 21.

Many people move to the Cranberry area to take advantage of lower property taxes than those in Allegheny County, while others come to the region after taking a job nearby, she said.

In 2015, builders spent $55.6 million to build 300 residential units in Cranberry, according to township data. That was up from $49.5 million and 196 units from 2014.

During the past decade, the township has averaged 60 to 100 new single-family homes each year and 50 to 60 single-family attached homes each year. Single-family attached units are typically either townhomes or quads. Officials anticipate those numbers to stay steady, said Ron Henshaw, township director of planning and development.

What has been increasing is the construction of apartment buildings, which typically have more than four units. Between 2006 and 2010, there were only 56 total multifamily units built. Since 2011, there have been 798 units, including a high of 358 in 2013.

“Companies like PPG, Westinghouse and others in Cranberry Woods are bringing in a lot of employees. A lot of them are younger folks who might not be looking for a home right away,” Henshaw said.

About 300 apartments have been approved for the Village of Cranberry Woods off Cranberry Woods Drive. It is up to the developer as to when those units are built, but they may get done this year, he said.

Adams Township has also experienced steady residential growth, though it does not yet have any large apartment buildings., said Gary Peaco, township code enforcement officer.

Last year, there were 190 new houses built in the township and officials expect to see that level continue indefinitely, Peaco said.

Adams still has a lot of undeveloped land that could be used for housing, and developers have recently shown interest in building a large development with apartments, though nothing has been proposed, he said.

Cranberry offers more access to major highways, but some people prefer Adams for the smaller Mars School District compared to the Seneca Valley School District that covers Cranberry, Peaco said.

“The difference between us and Cranberry is some people want the access, but they want to get a little farther away from the possible congestion,” he said.

Smigel said the general area has been in high demand ever since Interstate 279 was opened in the 1980s, creating a quicker route between Cranberry and Pittsburgh.

People see a lot of advantages to the Cranberry area.

“It has low taxes, convenient location, good schools, nice community, lots of amenities and an easy commute to the city,” Smigel said.

Selling houses for 27 years in the area, Smigel said she has sold to the same family three or even four times in some cases as they upgrade, but want to stay in the community.

“You have a constant flow of people. The townhome buyers move up to single-family homes once they have kids, and those buyers might go up to higher-end houses when their jobs improve,” she said.

Kaclik said demand for housing in all price ranges has been steady, though the demand for apartment rentals seems to have gone down slightly.

“I think that was due to the influx of gas and oil and people that came in a couple years ago, rental prices jumped up in the area, there was such a demand,” she said.

For people looking to buy a home, now is a good time because interest rates on mortgages are low.

“If you can get 3 to 3.5 percent locked in for the next 20 to 30 years, you’re doing pretty well. It’s appealing to people,” she said.

Cranberry still has plenty of land for development, Henshaw said.

About 29 percent of the township is undeveloped and there are parcels, particularly in the northern half of the township, where more housing is planned.

The supervisors earlier this year approved a 59-house development for property off Hope Road to be called Forest Edge.

Next month they will review a 22-house development proposed for off Old Ehrman Road to be called Eagle Ridge.

In addition to reviewing new development applications, the township also tracks the progress of construction on already-approved plans.

There are 22 developments under construction in the township, 14 of which are residential, according to the township’s website.
