Quick Facts

• Ocean setback requirements vary by state and local jurisdiction.
• The idea of setbacks is to provide a buffer zone between development and the ocean, helping to mitigate erosion and storm damage.
• Setbacks are typically measured from the ocean’s mean high water mark.
• In some areas, setbacks are based on a formula that accounts for factors like wind direction and wave height.
• Setbacks can be as little as 10 feet or as much as 500 feet or more, depending on the location and local regulations.
• Some coastal cities require setbacks to protect sensitive habitats like dunes and wetlands.
• In areas prone to erosion, setbacks may be longer to prevent damage to structures and infrastructure.
• The purpose of setbacks is to provide a zone for plants and animals to inhabit and for natural processes to occur.
• Setbacks can also help reduce the risk of flooding and storm damage to nearby properties.
• The effectiveness of setbacks in reducing erosion and hazard risk depends on various factors, including the distance of the setback and the quality of the existing coastal ecosystem.

What is an Ocean Setback?

An ocean setback is a minimum distance between a building and the mean high water mark (MHW) of the ocean. In simple terms, it’s the minimum distance required between your home and the beach. The setback varies depending on the location and the type of property you’re buying.

Types of Ocean Setbacks

There are two main types of ocean setbacks in Hawaii: County setbacks and Individual setbacks.

• County setbacks: These are the minimum setbacks required by the county for an area.
• Individual setbacks: These are setbacks imposed by the state or a federal agency.

Why Are Ocean Setbacks Important?

Ocean setbacks in Hawaii are crucial for several reasons:

• Environmental protection: Setbacks help prevent coastal erosion and protect sensitive habitats.
• Public safety: They ensure that buildings are not constructed in areas prone to flooding or storm damage.
• Property values: Well-maintained ocean setbacks can increase property values and attract buyers looking for proximity to the ocean while minimizing risks.

Determining Setbacks for Your Property

Determining the setbacks for your property involves a few steps:

1. Conduct a property survey: A professional surveyor will measure the property and determine the mean high water mark.
2. Research county regulations: Look up the county’s setback regulations for your area.
3. Check federal regulations: Consult with relevant federal agencies to determine if there are any national setbacks that may apply.
4. Get a permit: Before constructing a building, you’ll need to obtain a permit from the county.

Hawaii Ocean Setback Exceptions

While setbacks are essential for protecting our environment and public safety, there are some exceptions:

• Easements: Developers may obtain easements to reduce setbacks and build more homes.
• Designated areas: Counties may designate specific areas with different setback requirements.
• Historic preservation: Some properties may be exempt from setback requirements to preserve their historical significance.

Example: Ko Olina, Oahu

Ko Olina, a popular resort area on Oahu, has an average ocean setback of 50 feet. While some homes are built right on the beach, others are constructed with a significant setback to protect against coastal erosion.
