The $30,000 mistake AI could not warn her about

Start with the mechanical, electrical and plumbing engineer, not the permit office. Dr. Nikki Siso, founder of Conscious Kitchen in Westlake Hills outside Austin, did it the other way round, lost a month, and estimates it cost her $30,000 on a contractor she did not need. She asked AI for step-by-step guidance; it could not tell her the first step.

The same pattern repeated across permitting, health inspection and jurisdiction: strong at research, useless at process.

What did the sequencing error actually cost?

A month of delay and $30,000, by her estimate. The mistake was one of order, not effort.

"What I should have done is start with the MEP — the mechanical, electrical, plumbing engineer. MEP engineer should have been my first step. And because I didn't know that, it delayed me a month."

What she did instead: "I started with the planning permit department, waited for two weeks for a meeting with them, and then I had to wait two weeks for the engineer to come in. So that backlogged me a month."

"Had I known to start with the MEP, I would have had him in right away and then submitted that right away ... I would have saved thirty thousand dollars on a contractor."

Why she hired the contractor at all: "A lot of money, because I thought I didn't know what I was doing. And meanwhile, I was one person away from doing it all by myself."

Why couldn't AI answer the question?

It could find the paperwork but not the order. Siso asked directly for step-by-step guidance and reports that it did not have it.

"AI was missing the step-by-step guidance that I really needed. Surprisingly — because normally you can ask AI to say: hey, give me step-by-step guidance. But for some reason it didn't know. Start with the MEP."

What it could do instead: "It only could go to the health department and say: okay, you're gonna have to fill out this application, here's the link."

That distinction is the whole finding. Locating a form is not knowing the sequence, and the sequence decides whether you wait two weeks or two months.

What does the health inspector check that no website lists?

Water temperature, fridge temperature and printed documentation on the wall — none of which Siso could find in advance.

"Her most priority was to check that the fridges are at a certain temperature and that the water gets to at least 110. Those are her checks. That's what's gonna get past your failure. I didn't know that."

She also had to post printed COVID documentation over the bathroom sink and the kitchen handwashing sink, telling staff to report flu symptoms or a fever and take the day off. Her framing of the gap: she did not know all the steps the health code requires "even if their website doesn't list it."

The bathroom sink had cold water only. The fix was a $115 external tankless heater she installed herself in fifteen minutes, after a plumber quoted $250 for the installation.

Why does the jurisdiction matter more than the state?

Because requirements change between neighbouring municipalities, and a general-purpose tool will send you to the wrong one. In her words: "It is region by region. So Austin is very different than Westlake Hills."

Siso started on Austin's permitting site and describes that list as roughly ten times longer than the one she worked through in Westlake Hills, a smaller municipality she found faster to clear. The trap that nearly ended it was a search string:

"You have to put City of Westlake Hills, because if you just put Westlake Hills, you're taken to Austin."

She was filling out the wrong, much longer application until a person at Westlake Hills told her so. By her account she gave up "right at the last minute, one ... plan away."

What should you do before you file anything?

• Get the order from a human first. Ask a local contractor or municipal officer what the first step is. Her answer was one sentence long and worth $30,000.
• Type the jurisdiction exactly. "City of Westlake Hills," not "Westlake Hills." The wrong string produced a ten-times-longer application.
• Ask the inspector's office what is checked, not what the website lists. Fridge temperature, 110-degree water and posted signage were her three, and none were published.
• Price the small fixes before you hire out. A $115 heater and fifteen minutes beat a $250 install quote.
• Keep AI on the research half. Forms, product comparisons, long documents. Do not ask it what to do first.

How can you tell in advance where AI will fail you?

Ask whether the answer was ever written down. The wins in this interview — a 45-page lease read in three minutes, an oven chosen on specifications — were research tasks with public answers. The failures were process tasks whose answers live with local people: the MEP sequence known to contractors, the inspector's laminated form, the URL trap solved on a phone call.

Reading a commercial lease is objectively harder than knowing to call an engineer first. AI did the hard one and missed the easy one, because the easy one was never published anywhere a model could reach.

So before you trust an answer on anything with a permit, an inspector or a deadline attached, ask where this would have been written down, and by whom. If you cannot name the document, call someone local this week. What is the first step you have not verified with a human?
