Non-Traditional Dwellings 

The diversity of housing units in the U.S. represents the myriad of individuals that reside within them. Yet, the National Electrical Code (NEC) has to ensure a standardized regulatory approach that caters to each unique unit. Especially when the space in question might resemble a dwelling but is categorized differently by the NEC. 

Non-traditional dwellings pose a unique set of challenges: 

• The duration of an average stay. 
• The regularity of high-demand appliance usage. 

The NEC aims to ensure a balance; addressing these unique needs without overburdening stakeholders with excessive costs. 

Section 210.17, for instance, zeroes in on spaces that, while not traditional dwelling units, still need to adhere to some rules for dwelling units. This includes places like hotel rooms or suites equipped for longer stays with cooking provisions. 

2023 NEC - What has changed?

2020 NEC  

In the 2020 NEC, Section 210.17 required the following:  

Guest rooms and guest suites that are provided with permanent provisions for cooking shall have branch circuits installed to meet the rules for dwelling units.  

2023 NEC  

In the 2023 NEC, the revised Code section reads as follows:  

Guest rooms and guest suites in the following occupancies that are provided with permanent provisions for cooking shall have branch circuits installed to meet the rules for dwelling units:  

1. Hotels  
2. Motels  
3. Assisted Living Facilities  

In the previous Code update, terms like "guest rooms" and "guest suites" were used, suggesting places like hotels and motels. However, since these terms weren't explicitly mentioned, it led to debates among inspectors and electricians about their exact meaning. Adding to the confusion, the term "assisted care facilities," now included in the 2023 NEC, wasn't present or hinted at in the previous version. Yet, interestingly, many locations matched perfectly with the limited scope of this Code section.

For a clear definition of what qualifies as an assisted living facility, take a look at Informational Note No. 2 within the freshly revised Section 210.17. It points us to NFPA 101-2021, Life Safety Code, 3.3.198.12, Residential Board and Care Occupancy, which provides the following explanation:

"An occupancy used to provide housing and meals for four or more residents who aren't related to the owners or operators. The main purpose is to offer personal care services."

Section 210.17 in the 2023 NEC applies only to occupancies with permanent provisions for cooking.

The 2023 Code in Action

While the NEC doesn’t explicitly define a hotel or motel, references from external agencies like OSHA provide a framework. The key lies in identifying: 

• Types of facilities: Hotels, Motels, Assisted Living Facilities. 
• The existence of permanent provisions for cooking. 

Determining 'permanence' is crucial. Drawing from the NFPA's definition, anything intended to remain in place for over 180 days in a year is considered permanent. Practical examples include gas or electric ranges connected to fixed outlets or gas lines. 

However, ambiguity remains. Is an under-cabinet microwave permanent? While the NEC provides direction, final interpretation might still lie with the local authority having jurisdiction (AHJ). 

The NEC's 2023 revision illuminates areas previously shrouded in ambiguity, particularly around non-traditional dwellings. By naming specific establishments and shedding light on what constitutes 'permanent', the NEC is moving towards more clarity. However, as technology evolves and the definition of 'permanent' blurs, electricians and stakeholders should remain vigilant, seeking guidance when in doubt, and always aiming for safety and efficiency.

Scott: 
"Today, we're diving deep into the nuances of the 2023 National Electrical Code, specifically focusing on how it addresses non-traditional dwellings." 

[Cut to Scott in a modern kitchen, with various cooking appliances behind him.] 

Scott: 
"When you think of a home, you might imagine spaces like this. But what happens when the space resembles a home but doesn't fit the typical definition? That's where the NEC steps in." 

[The screen showcases the 2020 NEC's wording on guest rooms and suites.] 

Scott: 
"In 2020, the NEC had a straightforward directive about guest rooms and suites equipped with cooking provisions." 

[Cut to a split screen: One side shows a hotel room, and the other an assisted living facility room, both with cooking provisions.] 

Scott: 
"But 2023 brought clarity. The NEC now specifies that these guidelines apply not just to any rooms but those in Hotels, Motels, AND Assisted Living Facilities." 

[A short animation illustrates the difference between a countertop microwave and a fixed, under-cabinet microwave.] 

Scott: 
"But here's where it gets intriguing. What qualifies as a 'permanent provision for cooking'? Is it this countertop microwave, or the one fixed under the cabinet?" 

[Cut to Scott with the NEC book, flipping through its pages.] 

Scott: 
"The 2023 NEC guides us, referencing definitions from the NFPA. But, as with many things in life, there's a little room for interpretation." 

[Cut to a video clip of an electrician in discussion with an inspector, both looking at a blueprint.] 

Scott: 
"And when in doubt? It might come down to your local authority or AHJ. Always seek guidance to ensure you're on the right track." 

[Scott in a relaxed setting, the NEC book on the table next to him.] 

Scott: 
"In conclusion, the 2023 NEC sheds much-needed light on areas that needed clarity. It’s all about ensuring that even as our living spaces evolve, safety and efficiency remain paramount. Until next time, stay informed and stay safe."
