Building permit data can reveal a lot about a city or community. Places with fast-growing economies tend to have a higher demand for construction. Overall, building permits—particularly those that are residential—are extremely useful in estimating (and even projecting) city growth and change, including student growth rates, job counts, population growth, and overall economic well being. For these reasons, mySidewalk recently added building permit data to the tool. Now you can gather this data for your own city—and use it to find places of high growth as well as places that could use an economic boost.
