Understanding Floor Plan Measurements & Agent Liability

Transparency, accuracy, and your responsibility as a real estate professional.

At Lighthouse Visuals, we’re committed to delivering high-quality, ANSI-compliant floor plans and GLA (Gross Living Area) reports using trusted CubiCasa technology. These floor plans are designed to enhance your listings and provide an added layer of detail for buyers and sellers.

But when it comes to square footage and liability, there are important standards you need to know—especially in regulated states like North Carolina.

Why Do Floor Plan Measurements Vary?

Even among professionals, square footage can vary slightly. Five experts can measure the same property and each get a different result. That’s because of these factors.

That’s why documentation, consistency, and liability awareness are so important.

Methods

Measurement tools and techniques differ.

Discretion

Judgment calls are sometimes made in irregular layouts.

Standards

Standards like ANSI must be interpreted consistently.

Factors

Furniture, lightness, speed can also play a critical role in getting the best measurements possible.

What We Provide

ANSI-compliant floor plans using CubiCasa.
GLA reports that clearly document how square footage is calculated (uploaded to the FILES section
CubiCasa floor plans are generally accurate, with an average dimensional accuracy of 95-97%. For LiDAR devices, accuracy can be even higher, around 97%. However, accuracy can be affected by factors like scanning style, lighting conditions, and visibility of walls and floors.

CubiCasa is continually improving its algorithms to enhance accuracy.

These tools serve as a reliable, transparent marketing asset—but they are not a replacement for an appraisal.

Because Lighthouse Visuals is not a licensed appraisal firm, our floor plans are for marketing purposes only. Responsibility for square footage disclosure lies with the listing agent.
