Look up Ohio building codes in plain English.

What is this?

Google has a free tool called NotebookLM that lets you load documents and ask questions about them in plain English. It gives you answers with exact citations back to the source — so you can verify everything.

We loaded the Ohio Residential Code, Plumbing Code, Electrical Code, Mechanical Code, OSHA construction safety standards, and Summit County building department info into a notebook. Then we tested it with real questions contractors ask every day.

It works. And it's free. Below are the exact URLs you need to build your own notebook in about 10 minutes.

What you can ask it

Every answer comes back with the exact code section number cited. Tap the citation and it shows you the original text.

Your notebook is private. Your data stays yours.

When you create a notebook in NotebookLM, it belongs to you. Nobody else can see it unless you share it. Google does not use your uploaded sources or your questions to train AI models. It's tied to your Google account, just like your Google Drive. Think of it as your personal code reference that only you and your team can access.

It only answers from what you give it. No made-up information.

This is the big difference between NotebookLM and tools like ChatGPT or Google search. NotebookLM only pulls answers from the documents you loaded. If the answer isn't in your sources, it tells you "I don't have that information" instead of guessing. That's why every answer includes a citation you can tap to see the exact original text. You're not trusting AI — you're trusting the Ohio Residential Code, the NEC, and OSHA standards. The AI is just finding the right section faster than you can flip pages.

Build your own code notebook in 10 minutes.

Follow these steps and you'll have a searchable Ohio building code reference on your phone for free.

The free version of NotebookLM has a source limit (~20 sources). Start with the chapters you reference most and add more as needed. You can share the notebook with your crew so everyone has access.

Copy and paste these URLs into your notebook.

Organized by trade. Start with the ones you use most. Each URL is one chapter of code — click the copy button and paste it into NotebookLM as a website source.

Tip: Add your own sources too — manufacturer install manuals, equipment specs, your contract templates. Anything you load into the notebook becomes searchable in plain English with cited answers.

Once it's built, here's how to use it.

Answer code questions on the job site

You're in a crawl space, on a roof, or standing in a customer's kitchen and a code question comes up. Pull out your phone, open the notebook, and ask. You'll have the answer with the exact section number before you'd even find the right chapter in a physical code book.

Share it with your crew

NotebookLM lets you share your notebook with anyone who has a Google account. Build it once, share the link, and your entire team has the same code reference. Everyone's looking at the same answers from the same sources. No more "I thought the code said..." arguments on the job site.

Train an apprentice

New guy on the crew doesn't know why you need a vent within a certain distance of a trap? Instead of explaining it for the third time, tell them to ask the notebook. They get the code requirement, the reasoning, and the section number. They learn faster, you stay focused on the work, and they start building the habit of checking the code instead of guessing.

Prep for an inspection

Before the inspector shows up, run through your work with the notebook. "Does this bathroom need a dedicated 20-amp circuit?" "What's the minimum header size for a 6-foot opening?" Catch issues before the inspector does. It's a lot cheaper to fix something before drywall goes up.

Write better estimates and proposals

When a customer asks why something costs what it costs, you can point to the code. "The code requires GFCI protection in these six locations — here's the section number." That's not a sales pitch, that's a professional who knows the rules. It builds trust and justifies your price.

Settle a disagreement

You and a sub disagree on how something should be done. Instead of a phone call to the building department and a 45-minute hold, ask the notebook. It pulls the answer from the actual adopted code with a citation. Disagreement over.

Make it your own

The code chapters are just the starting point. Load in your go-to manufacturer specs, your company's scope of work template, your insurance requirements, your subcontractor agreements. The notebook searches everything you give it. The more you add, the more useful it gets.

It does more than answer questions.

NotebookLM has a built-in Studio that can turn your loaded sources into other formats. Here are a few that contractors find useful:

Audio Overview — code talk for the truck

The notebook generates a podcast-style conversation about your sources. Load your code chapters and listen to a summary on your way to the next job. Hand it to an apprentice and say "listen to this before tomorrow." It's code training that doesn't require sitting in a classroom.

Flashcards — study for your license on your phone

Studying for a journeyman exam or license renewal? The notebook builds flashcards directly from the code sections you loaded. Quiz yourself during lunch or between jobs. Have your apprentice run through them at the end of the day. Beats flipping through a code book with a highlighter.

Reports — hand your customer a professional summary

Ask the notebook to generate a report on "all code requirements for a bathroom remodel" and it builds a clean summary from your loaded sources. Print it, email it to a customer, or keep it in your truck. When a homeowner asks why the job costs what it costs, hand them the report and let the code speak for itself.

Studio also includes Mind Maps, Quizzes, Infographics, Slide Decks, and Data Tables. We cover all of these in our hands-on workshops. Visit smartcallsohio.com for upcoming sessions.
