1
How the rules stack (opens in a new tab)
Five layers set what a storage system must meet in Texas.
The layers from the product listing to state law. Each carries its citation and a seal that opens the source.
2
Codes in force (opens in a new tab)
Texas has no statewide fire code for private buildings.
The fire code in force with its instrument and date. Then NFPA 855, the electrical code, and the residential code.
3
State framework (opens in a new tab)
Texas has no state amendments to IFC Section 1207, because no state agency adopts the IFC for private buildings.
Where the state’s codes depart from the model codes for storage, or the laws that decide which codes apply.
4
Requirements by step (opens in a new tab)
State requirements in the order a project meets them.
Each requirement with when it applies and its citation, filtered to the profile you picked.
5
Local rules (opens in a new tab)
Cities and counties set most fire rules for storage in Texas.
Cities and counties with their own storage rules, the edition each enforces, and the date it took effect.
6
Laws, rules, and bills (opens in a new tab)
State laws, agency rules, and bills that change what storage products must meet, how they connect, or how owners are paid.
Enacted laws and rules first, then pending bills, then bills that did not become law. Each has its summary and source.
7
What changes between editions (opens in a new tab)
Texas adopted the 2026 NEC on Sep 1, 2026. The IFC rows apply to cities that move from the 2021 IFC to the 2024 edition. HB 3824 (2025) names NFPA 855 (2023) or later as a basis for state standards, so the 2026 edition’s changes appear too.
What changed for storage between the editions the state adopts, by topic. Each row names the proposal or section behind it.
8
Coming next (opens in a new tab)
Dates ahead for this state’s codes, its storage laws, and the standards they cite, earliest first.
Rulemaking steps and new editions of codes and standards ahead, with the date each takes hold.
9
Sources (opens in a new tab)
Every source a claim on this page cites, primary sources first.
Every page a claim cites, with its publisher, type, and the date it was read.

What the map says for a battery project in Texas

The guide draws these three codes from the map. The seal shows how each value was checked.

All seven Texas codes

The matrices

One is built from the new NFPA 855 research. Three the guide does not have yet; each will be built from state records the same way.

NFPA 855 edition and route by state

Built. The seventh code on the map: the edition each state reaches and whether it arrives through the fire code, a direct rule, or not at all.

Open the NFPA 855 page

UL 9540 and UL 9540A requirements by state

Planned. Research has not started. The matrix will show where a listing or a large-scale fire test report is required, with the size threshold in each state.

Residential battery placement rules by state

Planned. Research has not started. The matrix will show the placement limits each state enforces for a home battery under IRC R328, NFPA 855 chapter 15, or IFC 1207.

Local battery ordinances and moratoriums

Planned. Research has not started. The list will name the cities and counties with their own battery rules or a pause on new projects, with the record for each.
