Do Homeowners Need Permits to Build a Seawall?

Building a seawall on your property may seem like a straightforward improvement, but it involves a complex array of legal and regulatory considerations. Whether you own the land you plan to build on and the approval processes required can vary significantly depending on your location and local regulations. This comprehensive guide outlines the necessary steps and considerations for homeowners looking to construct a seawall.

Understanding Water Boundaries and Ownership

The concept of low-water and high-water marks can greatly influence who owns the land you plan to build on. These boundaries are crucial to determining whether you have complete ownership over the area intended for the seawall. A shoreline survey can help clarify these distinctions, dividing the land into various ownership categories. Understanding these distinctions is essential before proceeding with any construction plans.

Permits and Approvals

Regardless of water mark ownership, almost no improvements to private property can be made without obtaining the necessary permits and approvals from the governing authorities. This is especially true for complex structures like seawalls, which can have significant environmental and legal implications.

Federal Involvement and Jurisdiction

In many cases, federal agencies will hold a portion of the jurisdiction, primarily the Environmental Protection Agency (EPA) and the Army Corps of Engineers (ACE). For coastal properties, federal regulations will likely be involved as well. If the seawall is located within state lines, involvement from the state's regulatory bodies will also be needed.

Local Building Departments and Approval Process

One of the first steps in the process is visiting your local building department authority. Here, a building inspector will provide detailed guidance on which agencies must be involved in the approval process. They will also specify the required materials, designs, and construction methods for the seawall. Consulting with a local architect who has experience navigating this multi-agency process is highly recommended, especially if such projects are common in your area.

Impact of Improper Construction

While building a seawall can help protect your property from erosion and flooding, it is important to ensure that the construction is done correctly. Improperly constructed seawalls can lead to unintended consequences, such as increased erosion in other areas or property damage of adjacent properties. These domino effects can result in additional costs and legal issues.

Regional Regulations and Examples

The requirements for building a seawall can vary widely depending on the specific region. Here are a couple of general regional guidelines:

Coastal Property Regulations (East Coast)

For coastal properties on the East Coast, specific regulations and guidelines are in place. The local building department will have general guidelines and exemptions for seawall construction. For example, walls at the rear and back can be built if the height is below certain locally determined limits. However, for walls at the front or facing the public shore, stricter rules apply, and the use of acceptable materials and facings is more strictly regulated.

Lake Property Regulations

For properties near lakes, general guidelines for construction may include exemptions for walls constructed along the rear and back, provided the height is below certain locally determined limits. Front-facing or public-facing walls are subject to more stringent regulations. It is crucial to consult local building codes and possibly an architect familiar with these regulations to ensure compliance.

Conclusion

Building a seawall is a multifaceted undertaking that requires careful planning and legal compliance. Whether facing federal, state, or local regulations, it is essential to understand the specific rules in your area and navigate the approval process with diligence. Proper planning and adherence to regulations can help ensure the seawall serves its intended purpose without causing harm to neighboring properties or the environment.
