The question, "What is zoning?" is one that frequently arises when a construction project is being developed. Despite its critical importance, most people are unfamiliar with the term because they don't realize how essential zoning is to any project and how ignoring it can lead to significant problems. Zoning is the spacing between your buildings and property lines, with definitions about what that space can or cannot be used for. Different areas have different rules to what your zoning laws are to ensure safety, proper drainage, and more. This blog will go more in depth about what zoning is and list options for zoning information in Central Pennsylvania.

Zoning 101

Each project is unique, so paying close attention to your town’s coding regulations can help decide what you can do with your property. If there is one thing you walk away with from this blog, it’s that you should be checking your area’s code. The average construction project has permit ordinances regarding architectural styling, density of the project, height of the buildings, and placements of where the structure will be. This also includes distances where you can and cannot construct things, like where property lines fall or what type of structure may be constructed in its zone. The best example of this is seen in towns with commercial and residential districts, where your permit will also detail its approval through location. During the construction process, your build will typically undergo an inspection to ensure everything is up to code and ready for its intended purpose.

If you have accidentally or intentionally built anything before obtaining a permit, you should protect yourself by applying for a retroactive permit. These act as a blanket for “as-is” or “as-built” structures. This process requires more work overall, with a mandatory inspection taking place. Additionally, fees may be applied for breaking the order of permit before building. Although not every county has permits for everything, most counties have punishments for those that break the rules.

If people begin building before a permit is secure, there is a possibility that you will be penalized through fines, work stop orders, property liens, and other issues regarding insurance or future property selling. To look a little more in depth about the consequences of starting without a permit, check out this LegalClarity article.

Zoning Exceptions and Where to Find Them

When zoning regulations in your area change, there are typically two distinct types of exceptions that can apply. When zoning maps change, there is a possibility that you might be forced to move from your home. Grandfather clauses are often the first cited reason, frequently eliminating the urgency or need for change. This concept, sometimes referred to as "legacy clauses," permits individuals to maintain their existing living conditions and location. But depending on the location, grandfather clauses could be permanent, limited, or temporary.Be sure to check with your local office regarding any time limits or durations that may apply to your home. The second type of exception is zoning variance. Mostly utilized by businesses, this option acts as an inquiry to deviate from the current local zoning codes.If approved, the structure can be built according to the specifications in the zoning variance. These two exceptions may not apply to every situation or project, so always be sure to ask your local area about their rules regarding zoning exceptions.

Conclusion

No matter what your zoning code says, it’s important to not give up your dream. Instead, reimagine it. It might be better than ever due to the changes since often rules are put in place for a reason. Zoning is essential for preventing a host of problems, including an increased risk of natural disasters (such as fires and storms), the spread of illness, and a general lack of structural integrity in buildings. Zoning districts are a common feature in most areas. They are often established to manage resource allocation, prevent overpopulation, and serve other essential purposes for a township—like ensuring a factory doesn't suddenly appear in your neighborhood.
