Outside air exhaust and intake openings for commercial buildings must be located a minimum of _____ feet from a lot line.

• A. 5
• B. 30
• C. 10
• D. 3

Answer: (C)

Ventilation openings need a safe, code-based buffer from property lines to prevent drawing in contaminants and to ensure proper airflow and maintenance access. The minimum distance for outside air intakes and exhausts is 10 feet from a lot line. This spacing helps avoid re-entrainment of exhaust or other pollutants from neighboring areas and provides room for servicing and safe operation. Distances like 5 feet, 3 feet, or 30 feet do not meet this minimum requirement, with 30 feet being larger than necessary for a minimum, though larger separations can be allowed in some cases.
