## Pricing

from $3.30 / 1,000 results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## HUD Affordable Housing Explorer — LIHTC + Multifamily + Public Housing

One search across **three HUD affordable-housing programs**, returned as a **single unified property record** — with an **Opportunity Zone flag** computed for every property:

| Program | Source layer (HUD eGIS, keyless) | What it covers |
|---|---|---|
| `LIHTC` | `LIHTC/FeatureServer/0` | 40,500+ Low-Income Housing Tax Credit properties, ~2.6M units placed in service since 1987 |
| `HUD_INSURED` | `HUD_Insured_Multifamily_Properties/FeatureServer/0` | FHA-insured multifamily properties (221(d)(4), 223(f), 232, 202/811...) |
| `PUBLIC_HOUSING` | `Public_Housing_Developments/FeatureServer/0` | Public housing developments with PHA contact + occupancy stats |
| Opportunity Zones | `Opportunity_Zones/FeatureServer/13` | Designated Qualified Opportunity Zone tract polygons (point-in-polygon flag) |

No API key, no scraping-fragile HTML — this reads HUD's own ArcGIS services and normalizes every layer's incompatible schema (`PROJECT` vs `PROPERTY_NAME_TEXT` vs `PROJECT_NAME`, `LI_UNITS` vs `TOTAL_ASSISTED_UNIT_COUNT` vs `ACC_UNITS`...) into one clean shape you can filter, join, and map.

### Who uses this

- **LIHTC investors & syndicators** — screen existing tax-credit stock by state/city/size, spot properties in Opportunity Zones for stacked incentives, and pull owner names for outreach.
- **Affordable-housing developers** — map the competitive landscape (what exists, how many low-income units, year placed in service) before siting a new deal.
- **CRE lenders & brokers** — build lead lists of HUD-insured multifamily and LIHTC properties with unit counts and management contacts.
- **Housing researchers & journalists** — cross-program inventory of subsidized housing in any state, with coordinates ready for GIS.
- **AI agents** — a chainable MCP tool that turns "affordable housing near X" questions into structured rows.

### Example input

```json
{
  "states": ["CO"],
  "programs": ["LIHTC", "HUD_INSURED", "PUBLIC_HOUSING"],
  "city": "Denver",
  "minUnits": 50,
  "includeOpportunityZoneFlag": true,
  "onlyOpportunityZone": false,
  "maxResults": 500
}
````

### Output fields (one row per property)

- `program` — `LIHTC` | `HUD_INSURED` | `PUBLIC_HOUSING`
- `source_id` — stable HUD id (LIHTC `HUD_ID`, multifamily `PROPERTY_ID`, public-housing `DEVELOPMENT_CODE`)
- `property_name`, `address`, `city`, `state`, `county`, `zip`
- `units_total` — total units (null when HUD reports "not available")
- `units_low_income` — LIHTC low-income units / assisted units / ACC units
- `year_placed_in_service` — LIHTC year placed in service or multifamily occupancy year
- `owner_or_manager` — management agent (HUD-insured) or public housing authority. Null for LIHTC rows (HUD does not publish an owner/company in the LIHTC layer)
- `program_detail` — FHA program type, LIHTC allocation, or PHA code/status
- `latitude`, `longitude` — WGS84 coordinates (HUD enterprise geocode)
- `opportunity_zone` — true when the property sits inside a designated Qualified Opportunity Zone tract (computed locally by point-in-polygon; null if disabled)
- `oz_tract_geoid` — the OZ tract's 11-digit GEOID when flagged

Results are deduplicated within a run and priced per row (pay-per-event Result).

### Use as an MCP tool

This actor is exposed via [mcp.apify.com](https://mcp.apify.com) — AI agents (Claude, Cursor, custom agents) can call it as a tool. The input schema is fully described and the output rows are flat, typed, and field-documented, so an agent can chain it: e.g. *find LIHTC properties in Opportunity Zones in Denver over 100 units, then look up their owners*.

### FAQ

**How do I get a list of LIHTC properties by state?** Set `states` to your state codes and `programs` to `["LIHTC"]` — each row includes units, low-income units, year placed in service, allocation amount, and lat/lon. (HUD does not publish an owner/company in the LIHTC layer, so `owner_or_manager` is null for LIHTC rows; it is populated for HUD-insured and public-housing programs.)

**How do I find affordable housing properties in Opportunity Zones?** Set `onlyOpportunityZone` to `true`. The actor fetches the designated QOZ tract polygons for your states and keeps only properties whose coordinates fall inside one.

**Which HUD database does the LIHTC data come from?** HUD's national LIHTC database (the only complete national source on tax-credit project size, unit mix, and location), published through HUD's public ArcGIS services.

**Can I filter HUD multifamily properties by size?** Yes — `minUnits` filters on total units. Note some HUD-insured records (e.g. hospitals/nursing homes) report 0/unknown units and are dropped when a minimum is set.

**Is public housing included?** Yes — public housing developments with the operating housing authority as `owner_or_manager`. Year placed in service is not published for this layer.

**Does it work for the whole US?** Yes, any US state or territory code; query multiple states in one run. Data freshness follows HUD's own layer updates.

**Where do the Opportunity Zone boundaries come from?** HUD's `Opportunity_Zones` FeatureServer (designated QOZ tracts per IRC 1400Z-1). The flag is computed locally with ray-casting point-in-polygon — no paid geocoding APIs.

# Actor input Schema

## `states` (type: `array`):

2-letter USPS state codes to search (e.g. CO, TX, NY). Applied to every selected program layer. Defaults to \["CO"] if empty.

## `programs` (type: `array`):

Which HUD program layers to merge into the unified feed: LIHTC (Low-Income Housing Tax Credit properties), HUD\_INSURED (FHA-insured multifamily), PUBLIC\_HOUSING (public housing developments). Empty = all three.

## `city` (type: `string`):

Optional city-name filter (case-insensitive, prefix match). Example: "Denver". Leave empty for the whole state.

## `minUnits` (type: `integer`):

Only return properties with at least this many total units. 0 = no minimum. Note: some HUD-insured records report 0/unknown units and are dropped when this is set.

## `includeOpportunityZoneFlag` (type: `boolean`):

When true, fetch the designated Qualified Opportunity Zone tract polygons for each queried state and flag every property that sits inside one (adds opportunity\_zone + oz\_tract\_geoid to each row).

## `onlyOpportunityZone` (type: `boolean`):

When true, return only properties located inside a designated Qualified Opportunity Zone (forces the OZ flag computation on).

## `maxResults` (type: `integer`):

Maximum number of unified property rows to push to the dataset (each row = 1 billed result). 1-25000.
