Understanding what is a pre existing non conforming structure is essential for property owners, developers, and anyone involved in real estate or land use. These structures are buildings or uses that were lawful when established but no longer comply with current zoning regulations due to changes in zoning laws or zoning ordinances. This article explores the concept of preexisting nonconforming structures, the protections afforded to them, and how zoning and development regulations affect their existence and use.
A preexisting nonconforming structure refers to a building or use that was legally established prior to the adoption or amendment of current zoning bylaws or zoning laws but no longer complies with those regulations. For example, a building constructed before new zoning regulations were enacted may not comply with current front yard setback requirements or lot coverage limits. Despite not meeting current standards, such structures are often allowed to continue operating under what is known as a legal nonconforming use or legal nonconforming status.
These structures differ from prohibited or illegal uses because they were lawful at the time of construction or use. The key factor is that the property or structure existed prior to the effective date of the zoning bylaw or zoning ordinance that imposed the new restrictions. As a result, the property owner is typically granted protections under zoning and development regulations to maintain such structures, subject to certain limitations.
Zoning regulations and zoning ordinances establish the rules governing the use of land and buildings within a zoning district. These rules dictate what types of structures are permitted, their size, location, and use. When zoning laws change, existing structures or uses that no longer comply become nonconforming. The Massachusetts Zoning Act, for instance, provides guidelines on how these nonconforming structures and uses are treated within the state.
Under zoning bylaws, a nonconforming structure may continue to exist and be used, but any significant changes or expansions often require zoning relief, such as a variance or special permit from the zoning board. The property owner must seek approval before completing construction or making modifications that would increase noncompliance or alter the structure’s use to a substantially different purpose.
One of the primary protections for preexisting nonconforming structures is the grandfather clause. This provision allows such structures to continue operating as they did prior to the adoption of new zoning regulations. However, the protections are not unlimited. If the structure is abandoned or not used for two or more years, it may lose its legal nonconforming status.
Additionally, property owners may be restricted from expanding or altering the structure in ways that increase noncompliance with current zoning laws. For example, increasing lot coverage beyond what is permitted or changing the building’s use to one that is prohibited in the zoning district may not be allowed without zoning relief.
Building inspectors and zoning boards play a crucial role in determining whether a structure qualifies as a preexisting nonconforming structure and what modifications are permissible. They review applications for building permits and zoning relief to ensure compliance with applicable regulations.
Over time, zoning laws and development regulations may be amended, potentially affecting the status of nonconforming structures. Subsequent changes to zoning bylaws can establish stricter provisions or provide additional protections for such structures. Property owners must stay informed about these amendments to understand their rights and responsibilities.
If a nonconforming structure is substantially damaged or destroyed, rebuilding may be subject to compliance with current zoning regulations unless specific protections apply. Similarly, if the use of the property changes to a use that is no longer lawful or is substantially different from the existing use, the nonconforming status may be lost.
In summary, understanding what is a pre existing non conforming structure is vital for navigating the complexities of zoning and development regulations. These structures, while no longer fully complying with current zoning laws, are often protected under legal provisions such as the grandfather clause. Property owners should be aware of the limitations and requirements related to nonconforming structures, including the need for building permits, zoning relief, and adherence to applicable zoning bylaws and ordinances. By doing so, they can ensure lawful use, avoid penalties, and make informed decisions regarding their property within the framework of zoning regulations.
