When it comes to determining the value and livable space of a home, one of the key factors that is taken into consideration is the heated square footage. The heated square footage refers to the area of a home that is consistently heated and can be comfortably lived in. This measurement is important for both buyers and sellers as it directly affects the market value of a property.
However, the question arises: does unpermitted space affect the heated square footage? In other words, can areas of a home that were not permitted or approved by the local building authority be included in the calculation of heated square footage? In this article, we will explore this topic in detail and provide insights into how unpermitted space can impact the heated square footage of a home.
Understanding Heated Square Footage
To understand the impact of unpermitted space on heated square footage, it is important to first have a clear understanding of what heated square footage actually entails. Heated square footage is defined as the area of a home that is both heated and cooled by the home’s HVAC system. This includes rooms such as bedrooms, living rooms, kitchens, and bathrooms.
In general, finished areas that are above or below grade can be considered as heated square footage. This means that spaces such as finished basements or attics can be included in the calculation of heated square footage, as long as they meet certain criteria. These criteria may vary depending on the regulations and guidelines set by the local building authority or real estate commission.
The Impact of Unpermitted Space on Heated Square Footage
Unpermitted space, on the other hand, refers to areas of a home that have been modified or constructed without the necessary permits or approvals from the local building authority. This can include additions, renovations, or conversions that were done without following the proper legal procedures.
In most cases, unpermitted space cannot be included in the calculation of heated square footage. This is because these areas may not meet the necessary safety and building code requirements. Including unpermitted space in the heated square footage calculation could mislead potential buyers into thinking that the home is larger than it actually is, and could also raise concerns about the overall quality and safety of the property.
Exceptions to the Rule
While unpermitted space is generally excluded from the calculation of heated square footage, there are some exceptions to this rule. The North Carolina Real Estate Commission provides guidelines for including unpermitted space in the calculation of heated square footage, as long as certain criteria are met.
According to the guidelines, finished spaces like attics and basements can be counted as heated square footage if they meet specific requirements. These requirements include having adequate insulation, proper heating and cooling systems, and legal ingress and egress. Additionally, any unpermitted additions must be disclosed separately from permitted heated square footage when representing the square footage to prospective buyers.
It is important to note that these guidelines may vary between different states and regions, so it is always advisable to consult with the local building authority or a real estate professional to understand the specific regulations and guidelines in a particular area.
Determining Permitted versus Unpermitted Space
To accurately determine the heated square footage of a home, it is crucial to differentiate between permitted and unpermitted space. Permitted space refers to areas of a home that have been properly approved and permitted by the local building authority. These spaces typically meet the required building codes and safety standards.
Unpermitted space, on the other hand, includes areas that have been modified or added to a home without obtaining the necessary permits. This can include enclosed patios, converted garages, or other additions that were not properly documented or approved.
To determine whether a space is permitted or unpermitted, it is advisable to review the official building permits and documentation for the property. These records can provide valuable information regarding any additions or modifications that have been made to the home and whether they were done legally.
The Importance of Disclosure
When it comes to representing the square footage of a home to prospective buyers, it is crucial to provide accurate and transparent information. This includes disclosing any unpermitted additions or modifications separately from the permitted heated square footage.
Failure to disclose unpermitted space can lead to legal issues, as buyers may claim misrepresentation or fraud. It is important for sellers and real estate agents to be aware of the regulations and guidelines regarding the disclosure of unpermitted space in their specific area.






Unpermitted space can indeed affect the heated square footage of a home. While typically excluded from the calculation, there are exceptions where finished spaces like attics and basements can be counted as heated square footage if they meet specific requirements outlined by the local real estate commission.
It is important for both buyers and sellers to be aware of the regulations and guidelines in their specific area regarding the inclusion of unpermitted space in the calculation of heated square footage. Transparency and disclosure are key when representing the square footage of a home to prospective buyers, ensuring that they have accurate information about the livable space of the property.
