Bedroom Requirements: What Makes a Room a Bedroom

"Two bedroom" isn't a marketing claim — it's a legal standard. Here's what a room must have before anyone may sleep in it, plus the comfort thresholds that make it a bedroom worth having.

The code requirements (the must-haves):

• An egress window or door — a way out in an emergency. The window needs a minimum openable area (5.7 SF in most cases, with minimum height/width dimensions) and a sill low enough to climb through (max 44" above the floor). This is the rule that catches conversions: a garage's existing high strip windows don't qualify, so bedrooms there mean cutting new openings.
• Minimum size — habitable rooms need at least 70 SF and no dimension under 7 feet. (Nobody wants the 70 SF bedroom; it just marks the legal floor.)
• Ceiling height — 7'6" over the required area in most habitable rooms (some allowances exist for sloped ceilings — useful in above-garage and loft designs).
• Heat — habitable rooms must be heatable to a minimum temperature; your mini-split plan (lesson 7.7) should reach every bedroom.
• A closet? Not actually required by state code — but appraisers, tenants, and buyers all expect one, so functionally: yes, include it.

The comfort thresholds (the should-haves): a 10×10 fits a queen with walking room on three sides — the practical minimum for a real bedroom; 11×12 adds a dresser and desk without gymnastics. Under 10×10, call it what it is — an office or nursery — and market accordingly.

Design notes worth stealing: put closets on the wall shared with living space (free sound insulation); windows on two walls where the plan allows (there's lesson 8.1 again); and never route the only path to the unit's bathroom through a bedroom in a 2BR — that's a roommate plan with a design flaw.
