Egress Window Requirements for Bedrooms in St. Tammany Parish

Homeowners in St. Tammany Parish ask about egress windows most often when they remodel bedrooms or finish bonus rooms over a garage.

The short version is simple, every sleeping room needs at least one operable window or exterior door that allows a person to get out and a firefighter to get in without tools.

St. Tammany Parish enforces the Louisiana State Uniform Construction Code, which is based on the International Residential Code, and the egress rules below are the dimensions you should expect your permit reviewer to use.

What Counts as a Compliant Egress Window

Skip the legalese and use this working checklist for bedroom egress in the parish.

• You need at least 5.7 square feet of net clear opening, except grade-floor egress can be 5.0 square feet.
• Clear opening height must be at least 24 inches, width at least 20 inches, and the combination must still produce the full net area.
• Sill height cannot be more than 44 inches above the finished floor.
• Operation must be from the inside without keys, tools, or special knowledge, and any security devices must release with a simple single motion.
• Window wells must offer 9 square feet of clear space, 36 inches minimum width and projection, and any depth over 44 inches requires a permanent ladder or steps.

Those dimensions refer to the clear opening when the window is fully open, not the frame size on the sales sheet.

Because the sash opens fully, a casement frequently meets egress with less wall space, but double hung windows sometimes require a taller or wider unit.

Replacement windows can lose clear opening because of added frame mass, so confirm the egress dimensions on the exact model and size, not just the rough opening.

St. Tammany Specifics, Permitting and Inspections

In the parish, egress details are checked at permit plan review and again in the field during inspections.

Permits are generally required for new or resized bedroom windows, and egress compliance is a standard review item.

Homeowners often ask if window replacement permits required in St Tammany Parish Louisiana apply when swapping like-for-like units in a bedroom, and the answer is that permits are usually required when structural framing changes or the opening size changes, and some jurisdictions also require permits for insert replacements, so check with the parish permitting office before ordering.

Older homes are not exempt during replacement, if you touch the opening in a bedroom, the result must comply with current egress.

Tie in your alarm updates with the bedroom permit, because inspectors will check those along with the window.

Hurricane Glazing and Security Devices

Impact glass and storm protection are smart in this region, yet the egress size and interior operation rules do not change, you still need the same clear space and a no-tool release.

Any security device over a bedroom window needs a hand-operated interior release that is simple and visible.

Do not install permanent storm protection that locks the egress window shut from the outside.

Basements and Elevated Floors in the Parish

You do not see many basements here, yet if you have one, apply the same egress sizes and provide code-compliant window wells and ladders where required.

Elevated homes on piers are common, and for grade-floor exceptions on net area, the opening has to be at the grade level of the bedroom floor, not the height above the ground under the house.

Common Field Mistakes That Fail Inspection

Most egress fails stem from the same small set of oversights, all fixable if you plan ahead.

• Picking a nominal size without checking the actual clear opening once the sash is open, only to miss the 5.7 square feet target.
• Forgetting to re-check sill height after underlayment and finish flooring are installed.
• Fitting window guards without an interior quick release.
• Choosing a double hung size based on frame dimensions, not the single sash opening.

Cost, Scheduling, and Practical Tips

A new egress cut-in is a small construction project with framing changes and exterior repairs, and it often prices in the 3,000 to 8,000 range in many regions, with finishes and access driving the total.

Upgrading an existing opening to meet egress saves structural work, but you still budget for patching finishes and possibly altering the header.

Plan for a day on site for a simple replacement, and several days including exterior work for a new opening, plus extra time if weather interrupts exterior finishes.

Casements paired with the right low-E glass and carefully detailed flashing hit egress and doors Mandeville LA energy targets, just ensure interior treatments and screens do not clip the opening.

How Egress Ties Into the Rest of Your Window Plan

Getting It Right the First Time

Verify both the clear opening and final sill elevation with your real flooring build-up and chosen window.

Walk through how blinds, shades, and screens are installed so nothing blocks the opening or complicates the release hardware.
