If you’ve ever tried to look up a property tax map in Upstate New York, you know the struggle. It usually involves a clunky government website that looks like it was designed in 1997. But then there’s Essex County Image Mate.
It’s one of those tools that real estate agents and nosy neighbors use constantly, yet most people have never heard of it. Honestly, it’s basically the "back door" into the county’s real estate data. You can find out who owns that dilapidated cabin down the road or check if your neighbor’s assessment is actually lower than yours.
New York’s North Country is massive. Essex County covers a huge chunk of the Adirondacks, from Lake Champlain over to the high peaks. Keeping track of all those parcels is a nightmare. That’s where Image Mate comes in. It acts as a public-facing window into the Real Property Tax Service database. It’s not just a map; it’s a massive filing cabinet that happens to be digital.

What is Essex County Image Mate anyway?
Most people think it’s just a GIS map. It’s not.
While the system does have mapping features, the "Image" part of the name refers to the fact that it stores visual and data-driven records of every single land parcel in the county. We’re talking about over 50,000 tax parcels. This isn't Zillow. You won't find glossy photos of staged living rooms or "suggested" prices. What you find is the cold, hard data used by the Office of Real Property Tax Services (ORPTS).
The system is maintained by the Essex County Real Property Tax Service Agency in Elizabethtown. They use software from a company called SDG (Systems Development Group), which is why the interface looks identical to the systems used in Saratoga or Warren County. It's a standard across New York.
The stuff you can actually find (and why it matters)
You’re looking for specifics. Maybe you’re buying a hunting camp in Minerva or a vacation rental in Lake Placid. You need the truth, not a sales pitch.
Here is what is tucked away inside:
Tax maps and boundaries. Ever wonder where your property line actually ends? Don't rely on the Image Mate map for a legal survey—it even says so in a big scary disclaimer—but it gives you a very good idea of the shape of the lot.
Exemptions. This is the big one. You can see if a property has a STAR (School Tax Relief) exemption, a senior citizens exemption, or a veterans exemption. If you’re comparing two identical houses and one has taxes that are $2,000 cheaper, it’s probably because of an exemption that won't transfer to you.
Inventory data. Does the county think that house has four bedrooms or three? If the Image Mate says three but you see four, someone might have finished a basement without a permit. Or, conversely, the county might be overcharging the owner for space that doesn't exist. You’ll see the square footage, the year built, and even the type of fuel used for heating.
Recent Sales. The "Sales Search" tool is arguably the most powerful part of the site. You can filter by town—like Ticonderoga or North Elba—and see every arm's length transaction in the last few years. This is how you win a tax grievance. You find "comparables" that sold for less than your assessed value.

Why the "Public" vs "Pro" distinction is annoying
You’ll notice two login options. One is public. The other is for professionals.
Don't panic. You don't need a special license to see the basics. The public side is free and gives you 90% of what you need. The professional side is usually reserved for appraisers, title searchers, and real estate attorneys who need access to things like historical deed references (Liber and Page numbers) and more detailed tax billing history.
The quirks of searching in Essex County
Searching for a property is harder than it should be.
If you type "123 Main Street" and hit enter, you might get zero results. Why? Because the database is picky. Sometimes "Street" is "St" and sometimes it's just omitted. The pro tip is to search by Last Name or the SBL Number (Section-Block-Lot).
The SBL is the DNA of a property. It looks something like 155.1-1-10.000. If you have that number, you are golden. You can find it on an old tax bill.
Also, keep in mind that Essex County has a lot of "State Land." Since about half of the county is part of the Adirondack Forest Preserve, you’ll see massive swaths of land owned by the "People of the State of New York." Image Mate will show these, but obviously, there isn't much "inventory" data for a mountain top.
Common misconceptions about the data
People get mad at Image Mate. I've seen it.
They see an assessment of $300,000 on the site and think that's what their house is worth. Wrong. That is the assessed value, which is used for taxes. The market value is what someone will actually pay you. In a hot market like Lake Placid or Wilmington, the market value is often way higher than the assessment.
Another mistake? Thinking the photos are current.
The "Image" in Image Mate often includes a photo of the structure. These photos are sometimes ten years old. If you see a blue house on the screen but it’s painted white now, don’t freak out. The county doesn't send a photographer out every time you pick up a paintbrush. They usually only update photos during a town-wide revaluation.
How to use Image Mate for a tax grievance
If you think your taxes are too high, Essex County Image Mate is your best friend.
- Find your parcel. Look at your "Total Assessment."
- Use the Sales Search. Set the parameters for your town and your style of house (e.g., Ranch, Colonial).
- Look for the "Equalization Rate." This is a tricky number. If your town is assessed at 100%, then your assessment should equal your market value. If it's at 50%, your $100,000 assessment actually means the county thinks your house is worth $200,000.
- Print the comps. Find three houses similar to yours that sold for less than your "Full Market Value" listed on the site.
This data is exactly what the Board of Assessment Review (BAR) looks at during Grievance Day in May. If you show up with Image Mate printouts, they take you seriously.
Technical glitches and "down time"
Because this is a county-run system, it’s not always up.

Sometimes the server in Elizabethtown takes a nap on Sunday nights. If the maps aren't loading, it's usually a Java or browser compatibility issue. The system works best on desktop. Trying to navigate the tax maps on an iPhone while standing in the middle of a forest is a recipe for a headache. The interface just isn't responsive for mobile.
The weird history of tax mapping in the ADKs
Tax mapping in Essex County used to be a mess of hand-drawn paper maps.
Moving to a digital system like Image Mate was a massive undertaking. It required digitizing old vellum maps and reconciling them with modern GPS data. This is why you sometimes see "overlaps" where two properties seem to occupy the same space on the digital map.
If you see an overlap, don't start a fence war. The digital map is just a representation. The actual deed filed in the County Clerk's office is the law of the land.
Actionable Steps for Property Owners
- Verify your Inventory: Log in once a year to ensure your square footage and room count are correct. If the county thinks you have a finished basement and you don't, you're overpaying.
- Check for Exemptions: Ensure your STAR or Veterans exemption is actually showing up. If it's missing, call the assessor's office immediately.
- Monitor Nearby Sales: If you're thinking of selling, don't just look at Zillow. Look at the actual recorded sales in Image Mate to see what the county officially recorded as the sale price.
- Note the SBL: Write down your Section-Block-Lot number and keep it with your important papers. It makes every future interaction with the county 10x faster.
- Visit the Assessor: If the data on Image Mate is wrong, don't just complain. Take a screenshot, go to your local town hall (not the county seat, but your specific town assessor), and ask for a correction. They are usually pretty helpful if you have the data in front of you.
Managing property in the Adirondacks is complicated enough with the APA (Adirondack Park Agency) and local zoning. Using a tool like this gives you a bit of leverage and transparency that didn't exist twenty years ago. It's not flashy, but it works.
