I'd like to tell you about a moment that happens to almost everyone who buys a house and that nobody warns you about.
You're a few weeks in. You've signed the offer, you've cleared inspection, you've negotiated the credit for the dishwasher. The closing is on the calendar. And then, somewhere around week three, the paperwork pivots. It stops being about doors and roofs and starts being about chemistry.
You sign disclosures about the foundation. You read the inspector's report on the HVAC. You learn the roof has eight years left. You receive the title commitment. You initial the survey. And at no point — not once — does anyone hand you a piece of paper that says: here is what is in the soil, the air, and the public record around the place you are about to live for the next ten or fifteen or thirty years.
I noticed this gap during a Nashville home purchase, and I sort of couldn't stop thinking about it. Because here is the thing: the information exists. All of it. The Tennessee Department of Environment and Conservation knows where every registered underground fuel tank in the state is. The EPA knows where every federally-tracked contamination site is. Researchers at Barrow Neurological Institute and the Mayo Clinic published a study in JAMA Network Open in May 2025 — Krzyzanowski et al., Proximity to Golf Courses and Risk of Parkinson Disease — that found living within one mile of a golf course was associated with a 126% increased risk of Parkinson disease, likely tied to pesticide drift and groundwater contamination. Actual peer-reviewed work, in a real journal, that would have been useful to read before we toured a house near a country club.
The data is sitting there. Public. Free. Mostly accurate. Almost entirely unread.
So I started reading it.
I am going to be honest with you: the first version of Parcelscope was a spreadsheet. I would manually pull data from TDEC's UST database, cross-reference it with EPA Envirofacts, geocode addresses against the county parcel layer, and write up findings in a Google Doc. It took me about four hours per address. The product was, frankly, terrible. But the results were interesting enough that I kept doing it for friends, then for friends of friends.
What I noticed is that almost every Davidson County address has something. A closed gas station two blocks over from 1972. A dry cleaner that operated until the late nineties on the next street. A transmission corridor running along the back of a subdivision. A landfill that capped out in 2003 and is now a county park.
None of it was alarming. All of it was worth knowing. People wanted to know it.
The four-hour spreadsheet became a Python script. The Python script became an engine. The engine became Parcelscope.
Parcelscope reads thirteen public records — federal, state, and local — against a single Davidson County address and tells you what the records say in plain English. Forty-nine dollars. Twenty-four hours. A PDF you can read in one sitting with a cup of coffee. It is not a Phase I, it is not a soil test, it is not a substitute for your home inspector or your real estate attorney. It is what an exceptionally well-read neighbor would tell you about your address if your neighbor had read every public environmental dataset in the county and remembered all of it.
Right now I am building it alone, on a laptop, in evenings and weekends. The methodology is mine, the engine is mine, the voice on this page is mine. As Parcelscope grows that may change — I am open to a small team if the work calls for it — but the editorial sensibility will not. We will name our sources. We will read carefully. We will tell you what the record says without softening it for comfort or sharpening it for urgency.
I want to say something about that last part, because it matters to me.
There is a version of this product that leans into fear. Find out what's wrong with your home before it's too late. Discover the contamination they don't want you to see. A lot of consumer due-diligence products are built that way. Anxiety converts well. Investigation makes for sticky brand language.
That is not the version I am building, and I want to be plain about why.
The version I am building treats you, the reader, as a capable adult. You can read thirteen environmental records and decide what they mean for your life. A closed underground storage tank a quarter mile away is not a threat — it is a piece of historical context about your neighborhood, and somebody handled the closure in 2008, and that is part of how Nashville works. The dry cleaner on Hillsboro Road that closed in 1998 is not a reason to walk away from a transaction — it is a footnote, and a fact about commercial Nashville, and a reason to be a little curious about the soil chemistry of that particular block.
The country club in your neighborhood is not a dealbreaker. It is also not nothing. The Krzyzanowski study is real. The prevailing wind matters. You get to weigh these things and reach your own conclusion. My job is to put the geometry on the table cleanly and step back.
I am building this for the homebuyer who wants to understand their place. Not investigate it for problems — know it. Live in it with eyes open. Notice that the soil is karst and the air drifts in from the southwest most afternoons and the watershed they're in is the West Cumberland and that means the runoff from their lawn ends up in a particular set of waterways. Love their place more, by knowing it more.
This is, in the end, an environmental product made for people who care about their environment. Not in a panic. In a sustained, attentive, lifelong way.
A few things about what Parcelscope will become.
Right now it is Davidson County. Volume I. The reports cover the county where I live and where most of my early readers live. The Field Guide describes specific Davidson neighborhoods I know well — Belle Meade, East Nashville, the Nations, Inglewood, Donelson — and the environmental character of each.
Volume II, when it comes, will be wherever the work and the readers pull us. I have not decided. The point of calling this Volume I is to leave room for what comes next without committing prematurely. There are a lot of counties in Tennessee. There are a lot of Tennessees in the country. I am in no particular hurry.
What I am sure of is that Parcelscope will remain a publication. The reports are editorial documents. The website is a publication. The methodology is published. The voice is named — it is mine, until or unless someone else's voice joins it. And the source list is real.
If you read a Parcelscope report and find a number you want to verify, you can. The dataset is named. The retrieval date is named. The agency is named. We are not the source of the truth — the public record is. We are the patient reader of that record.
One last thing.
I started Parcelscope because I thought it should exist. That is a smaller reason than most startup origin stories, and I am okay with that. The gap is real. The work is interesting. The people who buy the report will be a little bit better-informed about their lives, and that is enough.
If you live in Davidson County and you are considering a home purchase, I hope Parcelscope will help you. If you are reading this from somewhere else and wondering when we will arrive, I do not know yet, but I am glad you are interested.
If you have feedback — on the methodology, on the writing, on what we should add or what we should never add — I would like to hear from you. The address is hello@getparcelscope.com. I read every email myself.
Welcome to Volume I.
