Honest writing on home health.

Why I built HomeFax — and what I found in my own home.

My family lives in North Scottsdale. The home is from 1989, slab foundation, on municipal water from the City of Scottsdale. By every measure, it's a "good" home in a "good" neighborhood. We bought it expecting safety to be the default.

It wasn't. I tested our water and found chromium-6, haloacetic acids, arsenic, and uranium — all within "legal" limits, but every one of them at levels I wouldn't drink given the choice. Our radon test came back at 2.1 pCi/L, below the action level but not zero. Our county is in the second-worst zone for ground-level ozone in the U.S. We back to desert preserve, which is beautiful and also wildfire-adjacent.

None of this was a surprise to anyone with the right expertise. It was a surprise to me, the homeowner. That gap is what HomeFax exists to close.

The problem with environmental information about homes

The data exists. EPA tracks every public water utility's compliance record. FEMA maps every flood zone. EPA publishes radon zones by county. AirNow tracks air quality in real time. The FCC registers every cell tower. USDA tracks agricultural land use. It's all public.

But it's scattered across twelve agencies, organized by region instead of address, and written for regulators instead of homeowners. To assemble it for one address takes hours, and you need to know what you're looking for.

That's a job for AI. Not "AI" as a buzzword — actual large language models that can read public databases and synthesize them for one specific address in plain English.

"You can keep guessing about your home, or you can know. The cost of knowing should be less than the cost of one bad surprise."

What HomeFax actually does

One address goes in. The AI cross-references the public databases, weights regional patterns against address-specific signals, and produces a report. Eight categories: water quality, radon, air quality, flood risk, Superfund proximity, build era, climate risk, and environmental proximity (golf courses, agriculture, EMF towers).

Each category gets a letter grade A through F, an honest plain-English assessment, and action items in three cost tiers. The first tier is always under $50.

We're not licensed inspectors. We're not replacing a real environmental site assessment. We're filling the gap between "I have no idea what's around me" and "I'm paying $2,500 for a Phase I ESA." For most homeowners, that gap is where the real decisions get made.

What's next

Right now reports are $49 for the first 100 customers, then $99. We're keeping the price low to learn fast. Every report goes through a quality check before it ships.

If you're curious what's actually around your home — the things you can't see and probably haven't been told — HomeFax is built for you.
