Residential Room Size Code Assistant Pro

Residential Room Size Code Assistant Pro

Plan residential rooms with clear dimensions, editable planning targets, and organized size-review reports directly inside AutoCAD.

This AutoLISP and DCL program helps you compare room measurements with a 2021 IRC dimensional reference while keeping practical design preferences separate from code minimums.

Includes 19 room types:

Living rooms, family rooms, dining rooms, bedrooms, primary bedrooms, guest bedrooms, kitchens, mudrooms, laundry rooms, home offices, one-, two-, and three-vehicle garages, bathrooms, powder rooms, foyers, walk-in closets, hallways, and utility rooms.

Pro features:

• Check applicable room-area, clear-dimension, basic flat-ceiling-height, and hallway-width thresholds.
• Identify dimensional deficits and items requiring manual review.
• Choose compact, comfortable, or spacious planning targets.
• Edit targets to suit your project.
• Measure supported rectangular room outlines from your drawing.
• Work in inches, decimal feet, or millimeters.
• Organize up to 200 rooms with floor labels and notes.
• Enter documented custom local thresholds.
• Save and reopen room-review projects.
• Export audit schedules to CSV.
• Insert an editable text report into your drawing.
• Use a classic gray DCL interface.

Your download includes:

• AutoLISP program and matching DCL interface.

Important: This is a dimensional planning and reference tool, not a complete code-compliance certificate. Planning targets are editable examples, not mandatory room sizes. Verify the adopted code, local amendments, room classification, and applicable exceptions with your jurisdiction. Egress, accessibility, fixture clearances, ventilation, structural requirements, and other provisions are outside this program’s checks.

Designed for Windows AutoCAD with AutoLISP, ActiveX, and DCL support. Automated core checks passed; native AutoCAD compatibility testing is still required.
