Regulatory framework
The code baseline for Van Zandt County.
The Van Zandt County Fire Marshal administers fire and life-safety permits and inspections in the county and applies applicable state fire-safety authority and National Fire Protection Association standards; the county has specifically enforced NFPA 855 (2020 edition) for battery energy storage facilities under Texas Local Government Code Chapter 233. The county's Subdivision Regulations, amended January 14, 2026, regulate roads, drainage, utilities, setbacks, plats, OSSFs, and floodplain development outside incorporated cities. OSSFs are governed by Texas Health and Safety Code Chapter 366, 30 TAC Chapters 30 and 285, and the county's TCEQ-approved amendments, including a one-acre minimum-lot policy unless a variance is supported. The county publishes no adopted general countywide IRC, IBC, electrical, plumbing, or mechanical-code edition for ordinary one- and two-family residential construction; incorporated municipalities apply their own codes.
