The minimum size for an access opening in usable crawl spaces under buildings without basements is indeed 24" x 18". This size is crucial to ensure that individuals can safely enter and exit the crawl space for maintenance, inspection, or repairs.

The standards set forth in the Florida Building Code reflect the importance of safety and accessibility, emphasizing that crawl spaces should be navigable while allowing for necessary accessibility to plumbing, electrical, and HVAC systems typically housed in these areas. The preferred dimensions not only comply with building safety regulations but also align with best practices in construction and maintenance.
