Public sector leaders and policy analysts rely on accurate housing policy data to shape effective policy, allocate resources wisely, and track progress toward community goals. Whether you’re examining affordability trends, evaluating assisted housing programs, or planning new housing initiatives, access to credible data sources is fundamental. This guide covers 5 authoritative housing policy data sources that government agencies, planners, and researchers use to inform evidence-based decision-making.
This list applies two filters before anything else: how the data is sourced, and whether it refreshes often enough to be useful for current decision-making. Only five sources cleared both bars.
Quick Overview List
- Dwellsy IQ — Unit-level rental data sourced directly from property management systems, refreshed continuously.
- Building Permits Survey / State of the Cities Data Systems — Census-collected construction permit data from nearly 20,000 jurisdictions, refreshed monthly.
- Survey of Construction — Joint HUD-Census survey of new residential construction starts and completions, refreshed monthly.
- Yardi Matrix — Subscription-based multifamily and SFR market data built on analyst outreach and property manager surveys, refreshed monthly.
- Apartment List National Rent Report — Rent index built from repeat-transaction activity on Apartment List’s own listing platform, refreshed monthly.
How We Ranked These Sources
Two rules decided this list, applied in order.
Rule 1: Sourcing method comes first
Data can reach a government researcher in four different ways, and those methods are not equally trustworthy:
- Direct system data: Captured where the transaction actually happens, such as a property management system recording a signed lease. This sits closest to the truth.
- Survey data: Collected by asking a property manager what a unit is renting for. It can be accurate at the moment it is collected, but it depends on what the respondent chooses to share.
- Internet listing service data: Reflects what is currently advertised as available, but demand signals can be distorted by the platform’s business model.
- Scraped data: Sits last because it inherits the limitations of listing data while adding risks such as duplication, staleness, and legal exposure from redistributing content the source may not have intended to share.
Rule 2: If it doesn’t refresh at least monthly, it’s not part of this list
A source can have an excellent methodology and still be unsuitable for tracking a market in motion if the next data point is a year or two away.
Within the same sourcing tier, frequency breaks ties. Between tiers, however, sourcing method always wins, even against a faster refresh rate. That means a monthly listing-based index still ranks behind a monthly survey, and a monthly survey still ranks behind data captured directly from the system of record.

1. Dwellsy IQ
Dwellsy IQ sources unit-level rental data directly from property management systems through the Dwellsy marketplace, the largest free rental listing platform in the country. Rents are captured where they’re set and updated, not inferred from a listing, not collected through a survey call. Data covers both single-family and multifamily rentals, with historical depth back to January 2020.
Key Features
- 17M+ listings sourced directly from property management systems, spanning 25,000+ property managers
- 250+ standardized attributes per listing, including final asking rent, unit specs, and amenities
- Coverage across 800+ MSAs and 16,000+ ZIP codes
- Historical data since January 2020
- Data can be scoped to a single state, county, or MSA rather than delivered as a national file
Best For
State and county agencies, regional planning commissions, and appraisal districts that need clean, jurisdiction-bounded rental data for affordability research, grant reporting, or planning work.
Pricing
Delivered as a one-time historical snapshot, a scoped data pull for a specific jurisdiction, or an ongoing feed for agencies that need ongoing monitoring, priced per project rather than locked into a single delivery model. Packages are available under common discretionary procurement thresholds; contact Dwellsy IQ for a scoped quote.
2. Building Permits Survey
The Building Permits Survey, conducted by the Census Bureau, collects residential construction permit data from nearly 20,000 permit-issuing jurisdictions nationwide. Data are aggregated through HUD’s State of the Cities Data Systems and other government portals. This is a near-complete collection of actual permit records, not a sampled survey, which places it just behind direct transactional data in reliability.
Key Features
- Monthly release, with roughly half of jurisdictions reporting monthly and the rest annually
- Permits broken down by structure type: single-family, multifamily, and manufactured homes
- Available at national, state, county, and select municipal levels
- Serves as a leading indicator, since permit issuance precedes construction starts and completions
Best For
Planning departments and MPOs tracking whether local construction activity is keeping pace with population growth or policy targets.
Pricing
Free. Data is published directly by the Census Bureau and HUD.
3. Survey of Construction
The Survey of Construction is a joint HUD-Census Bureau survey capturing new residential construction starts, completions, and unit characteristics. It complements permit data by showing whether issued permits actually translate into finished housing.
Key Features
- Monthly release, distinguishing housing starts from completions
- Detail on structure type, intended market (owner-occupied vs. rental), and region
- Includes construction timing and unit characteristics, useful for assessing housing quality and type
Best For
Agencies studying supply-side dynamics, particularly whether permitted construction is actually being completed and what kind of housing is being delivered.
Pricing
Free. Published by the Census Bureau, with regional and national aggregations.
4. Yardi Matrix
Yardi Matrix is a subscription market data platform built primarily on a monthly stratified sample survey, where a research team contacts a representative set of properties each month to verify asking rents, occupancy, and concessions. Yardi Matrix also incorporates some direct feeds from property management companies, though the core methodology is survey-based rather than a direct system-of-record feed. Coverage is strongest in multifamily.
Key Features
- Monthly national and metro-level reports
- Coverage across more than 150 U.S. markets
- Property-level detail including unit mix, ownership, and in-place loan information
- Primarily multifamily-focused, with more limited single-family rental coverage than PMS-sourced or permit-based data
Best For
Agencies whose research scope is multifamily-heavy and who have budget for a recurring subscription product.
Pricing
Subscription-based. Pricing is not publicly listed; contact Yardi Matrix for a quote. Worth flagging for public-sector buyers: this is a recurring subscription cost, not a one-time purchase, which may not fit a discretionary, project-based budget.
5. Apartment List National Rent Report
Apartment List publishes a monthly rent index built from repeat-transaction activity on its own listing platform: it tracks the same units being leased more than once and measures the change in transacted rent between those leases, similar in concept to a repeat-sales home price index. The baseline is anchored to American Community Survey data and extrapolated forward each month using platform transactions. Because it’s built from listings on a single platform rather than a direct feed from multiple systems like Dwellsy IQ and Yardi Matrix, it ranks behind sources with a stronger sourcing method, even though the monthly refresh rate is identical to Yardi Matrix and the federal surveys above.
Key Features
- Monthly national, state, metro, county, and city-level rent estimates
- Free, publicly downloadable data
- Same-unit, repeat-transaction methodology intended to control for changes in listing composition over time
Best For
Agencies that want a free, directional monthly rent trend and don’t need unit-level detail or jurisdiction-bounded raw data.
Pricing
Free.

FAQ
What’s the most reliable housing data source for government agencies?
Reliability depends on both how the data is sourced and how often it’s refreshed. Data captured directly from property management systems, like Dwellsy IQ, sits closest to the actual transaction. Federal administrative record collections like the Building Permits Survey are the next most reliable tier, since they’re near-complete counts rather than samples.
Why doesn’t the American Community Survey or American Housing Survey appear on this list?
Both are well-established federal surveys, but they refresh annually and biennially, respectively. This list is scoped specifically to sources that refresh at least monthly, since that’s the minimum cadence needed to track current market conditions rather than long-run trends.
What’s the difference between survey-based rent data and data sourced directly from property management systems?
Survey-based data is collected by asking a property manager or renter what a unit rents for, at whatever moment the survey is conducted. Data sourced directly from property management systems is captured at the point rents are actually set and updated in the system of record, without depending on what a respondent chooses to share or remembers accurately.
Can this data be scoped to a single county or state?
Yes, for Dwellsy IQ. Data can be delivered bounded to a specific jurisdiction rather than as a national dataset, which matters for agencies with budgets and mandates tied to a specific geography.
How do I choose between a free federal source and a paid source like Dwellsy IQ for a specific project?
Free federal sources are strong for supply-side tracking (permits, construction starts) and are appropriate when a project doesn’t require unit-level rent detail. A paid, directly-sourced option becomes worthwhile when a project needs current, jurisdiction-specific, unit-level rent data that a permit or construction survey simply doesn’t capture.
