Egress Window Requirements for Bedrooms in St. Tammany Parish

Any bedroom in St. Tammany Parish needs a code-compliant egress window, and inspectors look closely at a few core dimensions.

St. Tammany Parish generally follows the International Residential Code as adopted by Louisiana, with local amendments, so the core requirements are consistent across most single-family homes.

Below are the working dimensions and field checks we rely on when we frame and set bedroom windows.

Key Factors for Egress Window Compliance

What matters is the net clear opening, the usable space when the window is open, and that is smaller than the advertised unit size.

• You need at least 5.7 square feet of net clear opening above grade, and 5.0 square feet at grade or in a basement bedroom.
• Minimum net clear opening height is 24 inches, and minimum width is 20 inches, but hitting those numbers alone does not guarantee 5.7 square feet.
• Maximum sill height is 44 inches above the finished floor, measured to the top of the interior sill.
• Open from the inside without keys, tools, or special knowledge, with any bars or guards released by a single motion.

When the opening is below grade, code expects a window well with 9 square feet of clear horizontal area and 36 inches minimum in width and projection.

A well over 44 inches deep needs a ladder or steps attached, but not so bulky that they encroach on the 9 square feet of clear space.

Well covers are fine, but they need to be operable from the interior side with no keys or tools.

Selecting Egress-compliant Window Styles

Casement windows clear egress most reliably because the sash swings out and leaves a large net opening for a given frame size.

A double-hung might pass, but remember only the area above the lower sash when fully open counts, so you usually need a larger unit.

Slider units can pass, but the usable opening is just the space of the sliding sash, so verify the net opening before committing.

If you are selecting impact-rated glass and beefy frames for storms, double-check the net opening, since heavier profiles reduce clear space.

When I work in Mandeville, casements usually solve egress in smaller openings better than double-hungs, especially in older frames.

Choosing Materials for Egress Windows

Understanding the Costs of Egress Window Installation

Prices awning window replacement Mandeville LA vary by wall type, exterior cladding, and window spec, yet typical ranges stay fairly consistent.

For basements or grade-level bedrooms, a new egress opening with a compliant well typically runs 2,500 to 6,500, including digging, well, drainage, wall cutting, and patching finishes.

Upper-floor replacements that bring a bedroom into compliance generally fall in the 800 to 1,800 range per window, before upgrades like impact glass.

In a whole-home window job, egress openings can drive a higher unit cost because of size or additional features needed for compliance.

Practical Field Tips That Keep You Out of Trouble

Avoidable errors stall a lot of projects, especially when sizing from catalogs instead of net openings.

• Basing the order on overall frame size instead of the net clear opening.
• Letting interior finish flooring raise the sill above 44 inches after the window is already set.
• Putting in bars that require tools to remove from inside.
• Not providing well drainage, which often ends with a blocked, unsafe exit.

Confirm with the manufacturer’s egress data and a tape layout on the floor so you are not guessing.

Do not build a planter, deck step, or railing that blocks the exterior path from the egress window.
