Your Property Record Card: How to Find It and What Errors to Look For

Every property tax assessment is computed from a document you've probably never seen: the property record card. Pull yours, check it against reality, and you may find the fastest, most objective path to a lower bill — because a factual correction isn't a matter of opinion the way a valuation dispute is.

What a Property Record Card Actually Is

A property record card (sometimes called a property characteristics report, property detail report, or CAMA record) is the assessor's factual worksheet for your parcel. It lists the inputs their computer-assisted mass appraisal (CAMA) system uses to calculate your assessed value: square footage, room counts, lot size, year built, construction quality, condition, and any outbuildings or extra features like a pool or detached garage.

Why the Card Is the Whole Ballgame

This matters because the assessment isn't really an opinion about your house — it's a formula applied to these fields. Most counties multiply (or otherwise combine) square footage, quality grade, and condition against a cost or market schedule to land on a value.

If the record says your home has 2,400 finished square feet and it actually has 1,900, the formula runs on the wrong number and produces a wrong answer automatically, no judgment call required. That's what makes record-card errors the strongest appeal ground available: you're not arguing that the assessor's opinion of value is too high, you're pointing out that an input is factually incorrect.

Illustrative only: if your county's model applies roughly $150 per square foot and your card overstates finished area by 500 square feet, that single field could be inflating your assessed value by roughly $75,000 before any tax rate is even applied. The actual number for your property depends entirely on your county's own model and rate — this is only meant to show why square footage carries so much weight, not a prediction of what your correction is worth.

How to Find Your Property Record Card

There's no single national format — every county runs its own assessor's office and website — but the paths to find one fall into a few patterns.

The County's Online Parcel Search

Most counties now publish a "property search," "real property lookup," or "eReal Property" tool where you search by address, owner name, or parcel/PIN number. Two examples we checked directly:

• Wake County, NC runs its search at services.wake.gov/realestate, searchable by owner name, Real Estate ID, PIN, or street address. The county's companion Tax Portal goes further, telling homeowners directly to check that "your heated area, bathroom count, and other details are accurate" — which is exactly the record-card review this article walks through.
• Cook County, IL (Chicago) runs its search at cookcountyassessor.com/address-search, with a separate "Find Property Details" tool at cookcountyassessor.com/assessor-property-details that surfaces estimated value, assessed value, and the underlying property characteristics used to calculate them.
• Maricopa County, AZ (Phoenix) runs its own parcel viewer at mcassessor.maricopa.gov, a reminder that the exact tool name and layout — "eReal Property," "Property Search," "Parcel Viewer" — differs from county to county even though the underlying idea is the same.

These three counties alone span three different states and three different software setups, which is typical: expect the label and layout to differ, but expect nearly every county to have some version of this search.

The "Property Details" or "Property Card" Link

Once you find your parcel, look for a tab or button labeled "Property Details," "Characteristics," "Building Detail," or a downloadable PDF — the exact label varies by vendor. Most counties license their online GIS/CAMA portal from one of a handful of software providers, which is why the layouts often look similar across different states even though the county running the site is different.

Calling the Assessor's Office

If the online tool doesn't show characteristics, or shows less than you need, call the assessor's office directly and ask them to read you — or mail or email you — the record for your parcel. This is a routine, ordinary request. Assessment records are public information in essentially every state.

Visiting in Person

Assessor's offices are required to make these records available to the public, and staff can usually print the full card while you wait. This is also the best option if your county's online system is down or doesn't cover your property type.

Whichever path you use, look for the fields below specifically — they're the ones that drive value and the ones most likely to contain an error.

Field by Field: What to Verify

Go through your record card against your actual house, ideally with a tape measure, your closing documents, and any permits in hand.

Finished (Heated/Living) Square Footage

This is the single biggest value driver on most cards. Critically, check what's included. Garages, unfinished basements, porches, and unheated storage space usually should not be counted as finished living area — but data-entry mistakes that fold them in are common. If your card's total looks high relative to your own walk-around measurement, this is the field to dig into first. Our companion post on square footage errors on county records walks through how to measure and compare.

Bedroom and Bathroom Count

A room miscounted during a prior data collection, or a bathroom added by a previous owner that was never removed from the record, both skew value.

Lot Size

Confirm against your deed or plat map, not just the number on the card. Lot size errors are less common than square footage errors but do happen, especially on irregular or subdivided parcels.

Year Built

An error here can shift the depreciation the CAMA model applies to your home.

Construction Quality/Grade

Assessors assign a quality or grade code (for example "average," "good," or "custom") that acts as a multiplier. This field is more judgment-based than the others, but it should still reflect your home's actual materials and finish level — not a neighbor's or a builder's upgraded model.

Condition Rating

Similarly a multiplier. "Excellent" condition on a home that actually needs a new roof is an error worth flagging.

Number of Stories

Straightforward but occasionally wrong, especially on split-levels or homes with additions.

Basement: Finished vs. Unfinished

One of the highest-value fields to check, because "finished basement" typically adds meaningfully more per square foot than "unfinished basement" in most valuation models. See our deeper look at whether finishing a basement increases property taxes for how counties typically treat below-grade space.

Outbuildings, Pools, and Extra Features

Sheds, detached garages, pools, and similar features are listed and valued separately. If one was removed, demolished, or never actually built, but is still on the card, you're being taxed on something that doesn't exist.

The Highest-Yield Errors in Practice

Not all errors are equally common or equally valuable to fix. Based on what shows up most often in record-card reviews, four patterns account for most of the value at stake:

1. Overstated finished square footage — the most frequent and highest-dollar error, often from unfinished space (garage, basement, porch) getting folded into the "finished" total, or from an old addition being recorded at the wrong size.
2. A structure that was demolished or never built still sitting on the card — a shed, detached garage, or even a whole addition that shows up in the assessed value but doesn't exist in reality.
3. A finished-basement flag on a basement that isn't actually finished — or finished square footage recorded for a basement that's only partially finished.
4. An inflated quality or grade code — sometimes left over from a data-entry template default, or copied forward from a neighboring parcel during a mass reappraisal.

Any one of these can be worth checking even if you're not planning to file a full appeal this year.

How to Get an Error Corrected

Here's the part most homeowners don't know: in many counties, factual corrections to the record card don't require you to file a formal appeal at all.

Correction Requests vs. Formal Appeals

Filing a formal appeal usually means a specific window each year, a hearing, and an argument about value. A correction request is different — you're not arguing about value, you're telling the county their data is wrong, and many offices will simply fix it, often without the hearing process at all.

A County That Documents This

Salt Lake County, Utah spells this out explicitly. Its assessor's office states that "Property Owners are always welcomed year round to meet informally with staff, to correct errors in property characteristics and to discuss valuation issues," adding that "it is important to our office to correct any factual or valuation errors." That's a standing, non-appeal-season invitation to fix bad data — no formal filing window required.

Not every county runs it exactly the same way. Some route corrections through a general inquiry line, some through a specific "report an error" form, and some fold minor factual corrections into the same appeal system used for value disputes. If your county's site doesn't clearly describe a stand-alone correction process, call the assessor's office and ask directly whether factual corrections can be handled outside the formal appeal window. The pattern varies by state and county, but it's worth asking before you assume you have to wait for appeal season.

What to Bring

Whichever path your county uses, come prepared with evidence, not just an assertion:

• Your own measurements — a tape measure and a simple sketch of each finished level is often enough for square footage disputes.
• Photos — especially useful for proving a basement is unfinished, a pool was removed, or a structure was demolished.
• Floor plans, if you have them from a purchase, refinance, or renovation.
• Permits, which show what was actually built and when, and can cut both ways — use them to confirm your position either way.
• A private appraisal, if you have a recent one from a purchase or refinance; appraisers typically measure and describe the home independently, which can corroborate your numbers.

Set Your Expectations Honestly

A correction fixes the facts on file — it does not, by itself, produce an instant new tax bill. Most counties apply the corrected data on their normal assessment cycle, and the value adjustment that results may not be retroactive to prior tax years. Ask the assessor's office directly when a correction will take effect, and whether it applies going forward only or whether any refund process exists for past years. This varies by jurisdiction and isn't something to assume either way.

Conclusion

Before you spend time building a case about market value or comparable sales, spend twenty minutes confirming the assessor has the basic facts about your house right. It's the fastest, most objective place to look, and if there's an error, correcting it may not even require a formal appeal. Once your factual record is accurate, you can layer on a valuation argument if the number still looks high.

Quick answers: property record cards

Is a property record card the same as my tax bill?

No. The tax bill shows what you owe. The record card shows the underlying facts the assessor used to compute your assessed value, which the tax bill is then based on.

Is the property record card public information?

Generally yes — assessment records are public in essentially every state, which is why most counties publish them online without requiring you to prove ownership to view your own (or anyone else's) parcel.

Will fixing my record card automatically lower my tax bill?

Not automatically, and not necessarily this year. A correction updates the facts; the resulting value change follows the county's own assessment cycle and may not be retroactive. Ask the assessor's office how and when the correction will be reflected.

What if my county doesn't have an online property search?

Call or visit the assessor's office directly. Every county maintains these records even if it hasn't digitized public access to them.

Should I fix the record card or file a full appeal?

If the issue is a factual error — wrong square footage, a structure that doesn't exist, a wrong finished/unfinished flag — start with a correction request; it's typically simpler and often available outside the formal appeal window. If the facts are right but you believe the value is still too high relative to comparable sales, that's a valuation appeal instead. See what evidence wins a property tax appeal for that process.

How often do counties update these records?

It varies by jurisdiction — some counties re-inspect on a rolling multi-year cycle, others rely on permits and periodic mass reappraisals to trigger updates, and errors can persist for years between touches. That lag is exactly why it's worth checking your own card rather than assuming it's been kept current.
