Historic Mount Pleasant was the first preservation organization in the city to develop design guidelines based on the specific features of the houses in its neighborhood. The guidelines, originally published in 1991, known as the Green Book, due to its original green cover, is intended to assist Mount Pleasant residents when considering alterations or repairs to restore and preserve their homes and to facilitate compliance with DC’s historic district permitting process.
Those considering work on their property should also consult the design guidelines and procedures on the HPO website, including:
- Permits & Design Review
- Design Guidelines
- Design and Construction Standards and Guidelines
- Standards for Window Repair and Replacement
- Sign Standards
- General Guidelines by Topic
- Historic District Guidelines
- National Park Service (NPS) Standards and Guidelines
Among the most common preservation concerns addressed on the Guidelines page are Door Repair and Replacement, Window Repair and Replacement, and Basement Entrances and Basement Windows.
