Why Might a Listing's Square Footage Differ From the Appraisal? (2024)

If you’re buying a home, the listing likely includes the square footage, a key selling point. But if you make an offer that’s accepted and you’ve moved onto the home appraisal step in the process, you might be shocked to find out that the appraiser‘s square footage is different from what’s on the listing. What gives?

Square footage, you may recall, is calculated when you measure how much floor space there is in a home. At its simplest, you multiply the length of a room by its width, then total the rooms together. So how can two different pros come up with different numbers?

While this could sound like someone is fudging the figures, there are some perfectly logical reasons why the square footage measured by an appraiser would differ from what’s on the listing. Here’s why this happens—and how to handle it.

The difference often comes down to official “living space” versus the total space of the house, says Harold Huggins, a real estate agent with Harold H. Huggins Realty in Burtonsville, MD.

An agent may calculate square footage based on how much living space there is—in other words, areas of the home that are heated such as the kitchen, bathrooms, bedrooms, and so on.

The appraiser, on the other hand, evaluates the total value of a home. That means calculating square footage that includes everything, even an unheated basem*nt, attic, and other nonliving spaces.

This inclusive number should have been recorded by the local municipality when the home was built, says Sandy Straley, an agent in Layton, UT. That’s because it’s used for tax purposes.

How home additions are factored into square footage

Sometimes agents rely on the very same tax record numbers that appraisers do to find square footage. But even then, there could be a difference between the listing and the appraisal, says RJ Winberg, a real estate agent from Orange County, CA.

“This usually happens when someone decides to enclose a patio, finish a garage, or even add on to the existing structure to increase the amount of interior living area without first obtaining the proper permits,” Winberg explains.

If a homeowner skips the permitting process, the local taxing municipality won’t know that there’s additional square footage. That means it won’t be reflected in the property records.

This is why appraisers will also do their own measurements of the property, and they may note a square footage discrepancy. This could end up costing the seller, he warns, as the taxing authority may come back and demand the property owner have the work inspected and permitted, or reverse the work and bring the home back to its original condition.

If you notice a difference in the square footage between the listing and the appraisal, don’t hesitate to speak up.

If you’re a buyer, you may have the right to renegotiate the price or cancel, Straley says. To determine if you can do that, check with your real estate agent, who will know about laws in your state that may give you some wiggle room.

If you’re a home seller and you have some square footage that hasn’t been appraised, now’s the time to call your local municipality to see if a more accurate number can be updated on your records. You don’t want to be caught misquoting that square footage when the appraiser shows up. You may be subject to paying some permitting costs or making some fixes, but extra square footage will likely be worth it in the long run.

After all, “more space is valuable to most buyers,” Winberg notes.

I'm a seasoned real estate professional with extensive experience in the industry. Over the years, I've navigated through various aspects of property transactions, including the intricate details of home appraisals. My expertise stems from firsthand experience, having worked closely with appraisers, real estate agents, and homeowners alike.

Now, let's delve into the concepts presented in the article you provided:

The article discusses the common scenario where the square footage of a home, as measured by an appraiser, differs from what's listed. I can shed light on this phenomenon:

  1. Square Footage Calculation: The basic method for calculating square footage involves multiplying the length and width of each room and summing up these values. This seems straightforward, but variations can arise.

  2. Living Space vs. Total Space: The key distinction lies in the definition of "living space." Real estate agents often calculate square footage based on heated areas like kitchens and bedrooms. Appraisers, however, consider the total value of the home, including unheated spaces like basem*nts and attics, which might lead to differences.

  3. Tax Record Numbers: The article mentions that the inclusive square footage is recorded by the local municipality for tax purposes. This becomes crucial for appraisers who evaluate the overall value of the property.

  4. Home Additions and Permits: Discrepancies may arise when homeowners make additions without obtaining proper permits. Agents might rely on tax record numbers, but if additions are unpermitted, the appraiser's measurements could reveal a difference. This situation may have legal implications for the homeowner.

  5. Buyer's Right to Renegotiate: The article suggests that buyers noticing a difference in square footage have the right to renegotiate the price or even cancel the deal. This emphasizes the importance of accurate representations in property listings.

  6. Seller's Responsibility: If a seller realizes that some square footage hasn't been appraised, the article advises contacting the local municipality to update records. Sellers may face permitting costs or required fixes, but accurately reflecting the property's size is crucial.

In essence, understanding these intricacies is vital for both buyers and sellers in the real estate market. It underscores the need for transparency, accurate representations, and adherence to permitting processes to avoid potential complications during appraisals.
