Compare your calculation with the calculator results for verification.

Common Measurement Techniques

For accurate measurements:

Use a tape measure for interior dimensions
Measure from wall to wall, not including exterior walls
Record measurements in square feet
For irregular shapes, break the space into rectangles and calculate each area separately

The Formula Explained

The official Travis County appraisal formula for living area is:

Living Area = (Above-Ground Living Area) + (Below-Ground Living Area) - (Non-Living Area)

Where:

Above-Ground Living Area = Sum of all habitable above-ground spaces
Below-Ground Living Area = Sum of all habitable below-ground spaces
Non-Living Area = Sum of all non-habitable spaces (garages, storage, etc.)

The result is expressed in square feet, which is the standard unit for Travis County appraisals.

Key Assumptions

The Travis County appraisal formula makes several important assumptions:

All living spaces must be habitable and regularly used for living purposes
Non-living spaces must be clearly identified and excluded
Measurements must be taken from interior walls, not including exterior walls
The property must meet Travis County's minimum living area requirements

Minimum Living Area: Travis County requires a minimum living area of 500 square feet for residential properties. Properties below this threshold may be subject to additional assessment rules.

Worked Examples

Example 1: Single-Family Home

For a 1,800 sq ft above-ground living area, 300 sq ft below-ground living area, and 200 sq ft non-living area:

Living Area = (1,800 + 300) - 200 = 1,900 sq ft

Example 2: Multi-Unit Property

For a property with three units:

Unit	Above-Ground	Below-Ground	Non-Living
Unit 1	1,200 sq ft	100 sq ft	50 sq ft
Unit 2	900 sq ft	50 sq ft	30 sq ft
Unit 3	700 sq ft	0 sq ft	20 sq ft
Total	2,800 sq ft	150 sq ft	100 sq ft

Living Area = (2,800 + 150) - 100 = 2,850 sq ft
