Land parcel data for all properties in the City of Detroit from the Office of the Assessor. These are the parcel boundaries for the 2024 tax year. The Parcels data set from the City of Detroit Office of the Assessor is updated daily with land parcel data for all properties within the City of Detroit. Records in this data set describe the assessed values, rights, ownership interests, most recent sales data, physical descriptions, and addresses associated with each parcel. Parcels are distinguished from lots or plots of land in that property ownership rights are the fundamental units of division between parcels. The graphic depiction of land parcels represents real property ownership within the City for both privately and publicly owned properties.Data maintenance note: Databases used by the Office of the Assessor for parcels data are checked for updates daily. If an update is detected, the published Parcels dataset is then updated to reflect the most recent data available. Similarly, Zoning data provided by the Buildings, Safety Engineering, and Environmental Department (BSEED) Zoning Division is checked for updates daily. If any updates are available, values in the Zoning field are updated to reflect the most recent zoning data available. The "Data Updated" date for the Parcels dataset reflects the most recent date any data updates were detected and incorporated into the Parcels dataset. The GIS / Land Records Maintenance Division in the Office of the Assessor manages the data integrity of the parcel file.

In 2009, Data Driven Detroit partnered with Living Cities, the Detroit Office of Foreclosure Prevention and Response and Community Legal Resources (Michigan Community Resources) to conduct a survey of 1-4 unit residential structures and vacant lots in the City of Detroit. Surveyors went out in the field in August and September of 2009, and following this, data were entered into a database and cleaned. The survey collected information on property type, condition, vacancy, danger to the surrounding community, fire damage, and improvements on vacant lots.For more information on the DRPS, including aggregations and maps of the original data, please visit www.detroitparcelsurvey.org.Upon request, field description metadata is also available for this dataset.

This data is intended as a reference material of street and alley vacations, but not designed for survey, accurate positioning, or legal documents. It is created as polygon feature class, vacation information based on field measurements, types of Right of Way, and citations of Journal of the Common Council (J.C.C.) and the plat Liber and Page is listed under the column titled 'Sub_Plat'. The paper maps of the Street and Alley Vacation, the raster layer version of those maps (Linen Map Markup Mosaic), and the Detroit parcel layer are used as base maps to create this data.

The street and alley vacations were recorded from 1831 to 2022 throughout the whole city, and it will be updated weekly. The existed and/or active street and alley vacations are ready to view, the authors are working on pending and historical records.

Blight Violation Notices (BVN), or Blight Tickets, that have been issued to property owners who have violated City of Detroit ordinances that govern how property owners must maintain the exterior of their property. Blight Tickets are issued by city inspectors, police officers, and other city officials with the power to investigate and cite code violations. Blight Tickets are adjudicated as civil cases by the Department of Administrative Hearings (DAH), an independent quasi-judicial department established in January 2005 as a major component of the City's efforts to address blight. This dataset largely models the Blight Violation Case History system, which is administered by DAH and integrates data from departments that issue, process, and adjudicate blight violations. Blight tickets that are issued may be subsequently voided by the ticket writing department for various reasons. Property maintenance codes are described in Article 15 of the Detroit City Code. Article 15, Section 10 defines violations of Article 15 as blight violations, and Section 11 contains a schedule of civil fines assessed for specified violations.Blight Violations data is updated once daily.Click here for the Analytics Hub visualization of Blight Violations.

The Detroit Land Bank Authority (DLBA) was established in 2008 and is currently the largest property owner in Detroit. The properties of the land bank consists of vacant lots, abandoned houses, and other structures that were often forced into tax foreclosure. Its mission is to return the city's blighted and vacant properties to productive use. They utilize a variety of sales programs to make homeownership and land purchases accessible to Detroiters. Some of the larger programs include DLBA Owned Lots and Neighborhood Lots for Sale. The Detroit Land Bank Authority works directly with individual buyers, as well as Community Partner organizations and developers for projects big and small.Each row in this dataset lists a property that is currently owned by the Detroit Land Bank Authority within the city of Detroit. This includes fields such as Address, Parcel Number, DLBA Inventory Status, Neighborhood, and Council District.Click here for the Analytics Hub visualization of DLBA Owned Properties.For more information, please visit the DLBA website: https://buildingdetroit.org/.

A vacant building is defined as "a structure that is unoccupied for more than thirty (30) days, unsecured or secured by other than normal means, illegally occupied, or poses an imminent danger to the health and safety of the surrounding residents, properties or the general public." Buildings that meet this definition must be registered with BSEED as Vacant Properties.

In the fall of 2013, the Detroit Blight Removal Task Force commissioned Data Driven Detroit, the Michigan Nonprofit Association, and LOVELAND Technologies to conduct a survey of every parcel in the City of Detroit. The goal of the survey was to collect data on property condition and vacancy. The effort, called Motor City Mapping, leveraged relationships with the Rock Ventures family of companies and the Detroit Employment Solutions Corporation to assemble a dedicated team of over 200 resident surveyors, drivers, and quality control associates. Data collection occurred from December 4, 2013 until February 16, 2014, and the initiative resulted in survey information for over 370,000 parcels of land in the city of Detroit, identifying condition, occupancy, and use. The data were then extensively reviewed by the Motor City Mapping quality control team, a process that concluded on September 30, 2014. This file contains the official certified results from the Winter 2013/2014 survey, aggregated to 2010 Census Tracts for easy mapping and analysis. The topics covered in the dataset include totals and calculated percentages for parcels in the categories of illegal dumping, fire damage, structural condition, existence of a structure or accessory structure, and improvements on lots without structures.Metadata associated with this file includes field description metadata and a narrative summary documenting the process of creating the dataset.

Tentative 2024 land parcel assessment data for all properties in the City of Detroit from the Office of the Assessor. Tentative values in this dataset will not be locked in until the 2024 March Board of Review concludes, and may change as a result of the appeals process. Records in this data set describe the assessed values, rights, ownership interests, most recent sales data, physical descriptions, and addresses associated with each parcel.For more information on the assessment appeals process, please visit the Office of the Assessor's webpage.

The layer displays the roads and rights-of-way (sidewalks, berms, and dedicated public city land) that were either outright vacated or vacated with an easement. It is created as polygon feature class, vacation information based on field measurements, types of Right of Way, and citations of Journal of the Common Council (J.C.C.) and the plat Liber and Page is listed under the column titled "Sub_Plat". The paper maps of the Street and Alley Vacation, the raster layer version of those maps (Linen Map Markup Mosaic), and the Detroit parcel layer are used as base maps to create this data. The street and alley vacations are from 1831 to 2025 throughout the whole city, and it will be updated on monthly basis.For more information please visit the Maps and Records website.

Map of the Qualified Opportunity Zones in the City of Detroit. Data provided by the Detroit Economic Growth Corporation (DEGC) on the City of Detroit Open Data Portal, by census tract. Updated March 2018.

The Zoning District of every parcel in the City of Detroit. Zoning Categories as defined by City Planning Commission, updated in April, 2021.

The analyst downloaded the raw data used to develop this dataset from the Michigan Department of Environmental Quality (MDEQ). Pursuant to statutory guidelines under the Natural Resources and Environmental Protection Act (NREPA), the DEQ is required to “post on its website an inventory of residential closures and a separate inventory of other known facilities.” For the purposes of this dataset, “residential closures”have not been included; these were submitted to the DEQ in a No Further Action Report and satisfy remediation standards for Residential Facilities. All“other known facilities” available are included in the Inventory of Facilities dataset that serves as the foundation for this layer.

The Inventory of Facilities includes all locations where there have been a release of hazardous substances as defined under multiple subsets of NREPA. Although this list is commonly referred to as Brownfields, it can contain other types of designations including but not limited to: Leaking Underground Storage Tanks (LUST), Baseline Environmental Site Assessments (BEAs) and Environmental Site Assessments. Each of these designations requires further action, and the sites are pursuing cleanup in conjunction with the DEQ.

It is also important to mention that this inventory does not necessarily include every facility that is subject to NREPA’s guidelines, since owners are not required to inform the DEQ about the facilities and can pursue cleanup independently. Facilities that are not known to the DEQ are not on the inventory, nor are locations with releases that resulted in little or no environmental impact.Metadata associated with this file includes field description metadata and a narrative summary detailing the creation of this dataset.For more information about the Motor City Mapping project, please visit www.motorcitymapping.org.

The Neighborhood Enterprise Zones - Homestead (NEZ-H), 2006-2021 dataset was replaced with NEZ-H boundaries that were modified on June 15, 2021. This original historic dataset consists of NEZ-H district boundaries that were initially created between July 2006 and July 2008.

NEZ-Homestead is a tax abatement program intended to stimulate investment in existing residential structures. Within NEZ-Homestead Districts, residential property owners who occupy their homes as a principal residence and meet other program requirements are eligible to file for a tax abatement.

NEZ-Homestead differs from NEZ (also referred to as NEZ-NR) in that the Homestead program covers pre-existing residential property only. In contrast, NEZ-NR covers new facilities and/or rehabilitated facility projects. NEZ-Homestead and NEZ-NR programs are administered jointly by the City of Detroit and the State of Michigan under Michigan's Neighborhood Enterprise Zone (NEZ) Act, PA 147 of 1992 as amended.

See the NEZ Changelog “NEZ-H District Boundary Update” document for details on modifications to the dataset that occurred through August 17, 2018.Current NEZ-H district boundaries are available in the Neighborhood Enterprise Zones - Homestead (NEZ-H), Current dataset.

Wayne County follows a relatively fixed process for initiating tax foreclosures. The county serves notice to any parcel that is more than three years delinquent on property tax payments, and these properties are then sold to the highest bidder in two auctions - one in early September, and one in October. While there have been some exceptions to this schedule (a June 2012 auction of unsold foremost among them), properties listed in the September tax auction represent a strong proxy for identifying the universe of tax-foreclosed properties.

This file identifies parcels within the City of Detroit that were listed in the September Wayne County tax foreclosure auction in any year from 2002 through 2013. It contains information on year of foreclosure, as well as the total number of times that a property has been subject to tax foreclosure. The work to produce this dataset was conducted in September 2013, and the data were subsequently integrated into the Motor City Mapping project.

The purpose of this file is to help provide information on how Detroit's tax foreclosure crisis has developed over time, enabling community members and decision-makers to make more informed decisions when developing strategies to combat this growing problem.

Metadata associated with this file includes field description metadata and a narrative summary detailing the creation of the dataset.

The D3 vacancy index was designed to provide a more nuanced assessment of structural vacancy than the "occupied/unoccupied/maybe" categories used in the Motor City Mapping windshield survey. The dataset includes several sources, including Motor City Mapping, utility data, and other resources to create a score evaluating the occupancy status of a parcel. These values are then coded as "Likely Occupied", "Potentially Vacant", "Likely Vacant", and "Very Likely Vacant", helping to show a spectrum of vacancy across Detroit at three points in time: July 2014, November 2014, and May 2015.Because the vacancy index incorporates proprietary data sources, D3 is unable to release the raw values of the index to the public at the address level. To allow the public to obtain some of the benefit from this highly-effective tool, however, D3 aggregated this data to the Census block level. This file allows Detroit's policymakers and community members to track vacancy across the city using data that is as up-to-date as possible.Field description metadata are available upon request.
