Understanding Local Sign Regulations Before Installing Commercial Signs in Long Island

Most municipalities establish limits based on factors such as:

• Building frontage
• Storefront width
• Property size
• Building height
• Sign location

Larger signs are not always permitted simply because more space is available.

Choosing the right dimensions during the design stage helps avoid costly redesigns later.

Lighting Requirements

Illuminated signs are popular because they improve visibility during evening hours.

However, many municipalities regulate lighting to reduce glare and protect nearby residential areas.

Requirements may include:

• Maximum brightness levels
• Hours of operation
• Internal or external illumination
• Shielding to reduce light spill
• LED lighting standards

Businesses located near residential neighborhoods often face stricter lighting regulations.

Permit Requirements

Most permanent commercial signs require permits before installation.
