Why Interior Designers NEED to Know the Residential Codes

It is critical that designers who are producing residential floor plans understand the relevant code requirements. Codes are the law, and the requirements must be followed. 

Most often, if a designer draws a floor plan or lighting plan that misses code compliance, the licensed plumber or electrician, or the experienced carpenter or installer will recognize the deficiency, and make a correction on site or during installation. Within their specialty, good contractors are well aware of the requirements and keep up on any code requirement changes. Or, during a plan review for a building permit application, a code deficiency might get tagged for revision. And, even if something is installed or constructed incorrectly, a building inspector should catch it during an inspection (but then, of course, there may be a hefty cost to the homeowner to reconstruct the element per code requirements!!!)

This is all very comforting to designers. Mistakes and improper applications get caught and fixed along the way during plan reviews and construction. So, the real risk when a designer is ignorant of the codes is that they lose credibility with contractors and installers. AND, that gives the entire industry a bad name. 

Can you almost SEE the contractor rolling their eyes when they see a designer’s plan that has missed a basic requirement???

Can you almost HEAR the men on the job site chuckle over the silly designer’s scheme that misses the mark with plumbing, electrical, or life safety codes?

Yeah, right. This is why some designers get a bad rap.

And this is also why we at Dakota Design Company have developed the Residential Codes Handbook, which includes summaries and diagrams of ALL codes related to single-family homes. Additionally, we update it every three years when the International Residential Code (IRC) and the National Electrical Code (NEC) are revised, and we send all purchasers an update to keep them informed about any code changes.  

But in this post, we will cover the key areas where designers might miss the mark when it comes to code compliance. 

Interior designers excel at maximizing the visual elements within a space to achieve optimal solutions. We all recognize that a beautifully composed interior space is the result of meticulous planning and creative intuition. Designers manipulate visual elements to trick the eye, evoke specific moods, and enhance how people function within a space.

For instance, designers manipulate line to direct where one’s eyes should focus. Color is used to add visual interest and as a spatial corrector: by using colors that make elements advance or recede visually, to create a sense of balance and unity, or to create focal points and areas of emphasis. Texture and pattern add visual weight and interest to a space. Lighting is a sculptural tool that adds variation, creates depth, and highlights architectural features. Designers rely on symmetry and balance by organizing objects to provide a sense of order and reduce cognitive clutter.

Designers are skilled at all of these manipulations, and more. But all of these strategies rely on visual perception: what the inhabitants of a space can see visually. 

Although interior design is clearly predominantly a visual endeavor, this is not to say that designers ignore the other four senses, which are (in addition to sight): smell, touch, hearing, and taste. After all, design isn't just about what would look good in a photograph; it's about how a space feels when someone is actually experiencing it.

What is Multi-Sensory Focused Design?

Sensory-focused Design, also known as Atmospheric Design, focuses on ways people can experience interior spaces through their other four senses, in addition to sight. Intentionally adding elements that trigger smell, touch, hearing, and taste can greatly impact the experience of being in a specific space, making it emotionally resonant for the person.

In 2025 we wrote 70 blog posts! It didn't realize we wrote that many but I think it's because of our 2x/month articles for The Design Brief® (the newsletter Dr. Gloria writes where she shares lessons from design school, w/o the tuition FTW). 

So that means approximately 25 articles for The Design Brief® plus 45 regular blogs. That's wild. I'm happy with that. 

Here are the top ten articles you guys kept coming back to in 2025. A few of them surprised me.
