This web application shows your New York City Property Tax history and the change in market value, assessed value and the assessment ratio.  Each of these values are dictated by our 1980's law.  See https://www.nysenate.gov/legislation/laws/RPT/1805

When the change by our New York City Department of Finance varies from the law it is highlighted.  The variation maybe caused by repairs or changes to your property.

This is a class 4 property that changes to a class 1B property

This highlights the variation from the law.

Check your own property or your neighbors.

We will add a tax prediction next.  Basically, your tax will increase by 20% every five years for Class 1 (1 to 3 Family Residential homes) and 30% every five years for other properties.

This is a map of the relative property tax assessment for 1 to 3 family homes in NYC.

Blue = Low (e.g, 1 or 2 percent),

Red = High (e.g.,4 to 6 percent).

What is Assessed Value?

This is a number that NYC Department of Finance assigns to your property in order to tax you.

What is Market Value?

This is the amount that NYC Department of Finance believes your house will sell for approximately.

What is Assessment Ratio?

This is your assessed value divided by your market value.

Please note that for class 1 property the assessment ratio target is 6 percent but thanks to real estate law https://www.nysenate.gov/legislation/laws/RPT/1805 the assessment cannot change by more than 6 percent per year and 20 percent per 5 year period

Park Slope is mostly blue = Low Assessment Ratio

Dyker Heights / Bayridge is mostly red = High Assessment Ratio

There are 1968 cases of BIKING OFF LANE NYC.  What violation is that?  Is it for a bicycle not biking in the bike lane?  That does not appear to be against our laws.

1968	BIKING OFF LANE NYC

This data according to https://data.ny.gov/Transportation/Traffic-Tickets-Issued-Four-Year-Window/q4hy-kbtf is: 

"Traffic Tickets Issued: Four Year Window"

Data extracted from records of tickets on file with NYS DMV. The tickets were issued to motorists for violations of: NYS Vehicle & Traffic Law (VTL), Thruway Rules and Regulations, Tax Law, Transportation Law, Parks and Recreation Regulations, Local New York City Traffic Ordinances, and NYS Penal Law pertaining to the involvement of a motor vehicle in acts of assault, homicide, manslaughter and criminal negligence resulting in injury or death.

Limitations:

This data set reflects only the issuance of traffic tickets. The data cannot be used to determine convictions, dismissals or other aspects of ticket disposition. The data does not include tickets issued in the five Boroughs of New York City for misdemeanor or felony violations. Examples are: — DWI/DWAI and aggravated unlicensed operation; — Penal Law offenses involving the use of a motor vehicle in acts of assault, homicide, manslaughter and criminal negligence resulting in injury or death; and — Tickets for non-misdemeanor/felony offenses that were issued during an arrest for a misdemeanor or felony violation.

Choropleth of NYC Real Property Changes

This data is up to date as of the end of the month.

See https://nycopendata.socrata.com/City-Government/ACRIS-Real-Property-Master/bnx9-e6tj if you want to see when our NYC data is updated.

At this point in time, the NYC Real Property dataset is updated Jan 8, 2016 but the data only includes information from the end of the previous month (in this case, Dec 31, 2015)

If you want, daily updates of this public information you will have to pay $172,270.00

See http://www1.nyc.gov/assets/finance/downloads/pdf/05pdf/acris_fees.pdf

So if you want all the public data including document images and digital "meta" data for a year for all locations it would be $172,270.00

See https://a836-acris.nyc.gov/CP/CoverPage/login/?hid_loginSource=EDS to login and order the data

See http://acris.nyoss.com/SDS/Overview/How%20To%20Process%20ACRIS%20Daily%20File%20v1%207.htm for instructions from NYC DOF for processing their "Daily File"

But the https://cityregister.firebaseapp.com/ link gives you the digital data but it is delayed by 1 to 30 days plus about a week (NYC DOF upload delay) for much lower cost.

One question, why is the NYC DOF upload process not run every day?  It appears it would cost very little since the update process already exists.
