Lighting Regulations in Pittsboro, North Carolina: Balancing Historical Charm with Modern Standards

Introduction

Nestled in the heart of Chatham County, Pittsboro has maintained its historical charm since its founding in 1787. Named after William Pitt the Younger, this town of approximately 4,000 residents takes pride in preserving its architectural heritage while adapting to modern needs.

• Noncutoff: No light intensity limitations above maximum distribution
