Safety Glass Rules for Home Windows in LaPlace

Written by Big Easy Windows

Where Do Tempered Glass Requirements Apply in a Louisiana Home?

Quick Answer: Tempered glass requirements in Louisiana homes come from the International Residential Code as the state has adopted it. The code doesn’t call for safety glass in every window. It names specific hazardous locations where a person could fall against or push through the glass, and in those spots the glazing has to pass a human impact test. Tempered glass is the most familiar way to meet that rule, and laminated glass can meet it too. In LaPlace, that matters most when a storm or an accident breaks a pane and you’re deciding what goes back in.

The state’s code council lists the 2021 International Residential Code as the edition in effect since January 1, 2023, and its published schedule has the 2024 editions taking effect on January 1, 2027. The section references below come from the 2021 code.

What Makes Glass “Safety Glazing”?

Under Section R308.3.1 of the 2021 code, glazing in hazardous locations has to pass the impact test in the federal safety standard for architectural glazing, CPSC 16 CFR 1201, with the code allowing ANSI Z97.1 as an alternative in some cases. Two common glass types get there in different ways, as manufacturer Cardinal describes them:

• Tempered glass resists breakage and, when it does break, falls apart into small, blunt pieces.
• Laminated glass bonds glass to an interlayer and stays intact in the frame after it cracks. Cardinal certifies its laminated safety glass to CPSC 16 CFR 1201 and ANSI Z97.1, with the category tied to interlayer thickness.

Ordinary annealed glass is neither. It breaks into large, sharp fragments, which is exactly what the code is trying to keep out of these locations.

Which Spots in a House Count as Hazardous Locations?

The 2021 code lists 7 situations in Sections R308.4.1 through R308.4.7. Here’s what each one covers, in plain terms. Every item has exceptions, so treat this as a guide to what to ask about, not a final ruling on your house.

Glass in Doors

Glazing in the fixed and operable panels of hinged and sliding doors is a hazardous location, and bifold doors are included. Exceptions include openings too small for a 3-inch sphere to pass through and decorative glazing.

Glass Beside a Door

A window or sidelight next to a door counts when its bottom edge is less than 60 inches above the floor and it’s within 24 inches of either side of the closed door in the same plane. Glass on an adjoining wall within 24 inches of the hinge side of an in-swinging door can count too.

Large, Low Window Panes

An ordinary window becomes a hazardous location only when it meets all 4 conditions at once:

• The exposed area of a single pane is larger than 9 square feet.
• The bottom edge of the glass is less than 18 inches above the floor.
• The top edge is more than 36 inches above the floor.
• A walking surface sits within 36 inches of the glass, measured horizontally.

That describes the big, low picture windows many living rooms have. Raise the sill or shrink the pane and the rule may no longer apply.

Glass in Guards and Railings

Glass in a guard or railing counts as a hazardous location regardless of its size or height above the walking surface. That includes structural glass baluster panels and nonstructural in-fill panels.

Glass Near Tubs and Showers

Glazing in walls or enclosures containing or next to bathtubs, showers, hot tubs, and pools counts when its bottom edge is less than 60 inches above the standing or walking surface. Glass more than 60 inches horizontally from the water’s edge is excepted. A bathroom window over the tub is the classic case, and our post on bathroom window privacy covers the obscure glass options people pair with it.

Glass Beside Stairs and Landings

Glass counts when its bottom edge is less than 36 inches above the walking surface of a stairway or ramp, including landings between flights. Near the bottom landing, the zone reaches out in a 60-inch arc from the bottom tread. A properly installed rail or guard can create an exception.

How Do You Tell If a Pane Is Already Safety Glass?

Look at the corners. Section R308.1 requires each pane in a hazardous location to carry a manufacturer’s designation naming who applied it and the type of glass, along with the safety glazing standard it meets, and that mark has to be visible once the glass is installed. It can be etched, sandblasted, ceramic-fired, laser-etched, or embossed into the glass, or applied as a label that can’t come off without being destroyed.

No mark in a hazardous location is a reason to ask questions, especially in an older house where a pane may have been swapped at some point. Don’t try to test glass by tapping or scratching it. A glass company can identify what you have.

Does Impact Glass Count as Safety Glass?

Not automatically. Impact-rated windows are tested for wind-borne debris, and that’s a different test from the human impact standard behind safety glazing. Laminated glass can satisfy both when it’s certified and marked for each, which is why the mark matters more than the sales description.

If you’re adding impact-resistant windows in a spot the code treats as hazardous, ask for the safety glazing mark or documentation on those specific units. The same question applies to hurricane and storm windows in LaPlace.

Why the Question Comes Up in LaPlace

In LaPlace, the question can come up right after a storm breaks a pane. Hurricane Ida’s center passed just west of LaPlace early on August 30, 2021, according to the National Hurricane Center. Our storm-damaged windows decision guide covers the first steps after that kind of damage.

When the broken pane sits in one of the hazardous locations above, we recommend replacing it with marked safety glazing, even if the original glass was never marked. It’s the lower-risk choice for anyone who lives there.

Permits in St. John the Baptist Parish

St. John the Baptist Parish issues building permits through the Permit Division of its Planning and Zoning Department, on the first floor of the government building at 1811 W. Airline Highway in LaPlace. The parish lists renovation among its residential permit types. Call the Permit Division at (985) 651-5565 before work starts and ask whether your glass or window job needs a permit.

If a remodel changes a bedroom window’s size, egress rules come into play as well. Our guide to egress window requirements in Louisiana explains those.

Frequently Asked Questions

Do all windows in a new Louisiana home need tempered glass?

No. The code requires safety glazing only in the hazardous locations it defines, such as glass in doors and certain large, low panes. Most windows in a typical house don’t meet those conditions.

Is the glass in my shower door required to be safety glass?

Glass in doors and enclosures around showers and tubs falls under the hazardous location rules, with limited exceptions. Look for the permanent mark in a corner of the panel.

Can I replace a broken pane with regular glass if the old one wasn’t tempered?

If the pane is in a hazardous location, use marked safety glazing. Ask the parish permit office how the current code applies to your repair.

Does the same rule apply to storefront glass?

Commercial buildings follow a different code. Our post on commercial window and storefront glass covers that side.
