Craigslist Scraping: Extract Listings, Real Estate and Classifieds Data

Craigslist remains one of the most visited classifieds platforms in the world. Despite its famously minimalist design, it hosts millions of active listings across categories ranging from real estate and vehicles to jobs and services — spread across hundreds of city-specific subdomains covering virtually every metropolitan area in the United States and many international cities.

For data analysts, real estate investors, market researchers, and developers building aggregation tools, scraping Craigslist offers access to hyper-local market data that simply isn't available anywhere else.

In this comprehensive guide, we'll explore Craigslist's unique data architecture, walk through practical scraping implementations in both Node.js and Python, tackle common challenges, and show how to scale your extraction using Apify's cloud scraping platform.


Understanding Craigslist's Data Architecture

Craigslist is architecturally unique among major websites. Understanding its structure is essential before writing any scraping code.

Geographic Subdomain System

Unlike most platforms that use URL paths for location, Craigslist uses subdomains — one per metropolitan area:

  • newyork.craigslist.org — New York City
  • sfbay.craigslist.org — San Francisco Bay Area
  • chicago.craigslist.org — Chicago
  • losangeles.craigslist.org — Los Angeles
  • seattle.craigslist.org — Seattle

There are over 400 active subdomains covering US cities and international locations. Each operates as essentially an independent instance with its own listings.

Category Hierarchy

Within each city, listings are organized into a deep category tree:

craigslist.org
├── community
├── housing
│   ├── apts / housing (apa)
│   ├── rooms / shared (roo)
│   ├── sublets / temporary (sub)
│   ├── housing wanted (hou)
│   └── real estate for sale (rea)
├── for sale
│   ├── antiques (ata)
│   ├── electronics (ela)
│   ├── furniture (fua)
│   ├── cars+trucks (cta)
│   └── ... 30+ subcategories
├── services
├── jobs
│   ├── software / qa / dba (sof)
│   ├── web / info design (web)
│   └── ... many subcategories
└── gigs

Each category has a three-letter code used in URLs. For example, apartments for rent in San Francisco:
https://sfbay.craigslist.org/search/apa

Listing Structure

Every Craigslist listing contains these data fields:

  • Title: The listing headline
  • Price: Displayed in the title line (e.g., "$2,500/mo")
  • Location: Neighborhood or area within the metro region
  • Post date: When the listing was created
  • Post ID: A unique numeric identifier
  • Body text: The full description
  • Images: Uploaded photos (often multiple)
  • Map coordinates: Latitude/longitude when provided
  • Attributes: Structured metadata (bedrooms, sqft, etc. for housing)
  • Contact method: Reply link (anonymized email) or phone number

Search and Filtering

Craigslist supports several URL-based search parameters:

Parameter Description Example
query Search keywords query=furnished+studio
min_price Minimum price min_price=1000
max_price Maximum price max_price=2500
sort Sort order sort=date or sort=priceasc
hasPic Has photos hasPic=1
postedToday Today's posts only postedToday=1
bedrooms Number of bedrooms min_bedrooms=2
bathrooms Number of bathrooms min_bathrooms=1
sqft Square footage minSqft=500&maxSqft=1200

Basic Scraping: Node.js with Cheerio

Craigslist uses server-rendered HTML, which makes it one of the simpler major sites to scrape — no headless browser required for basic extraction. Here's a practical implementation using Node.js:

const axios = require('axios');
const cheerio = require('cheerio');

class CraigslistScraper {
    constructor(city) {
        this.baseUrl = `https://${city}.craigslist.org`;
        this.headers = {
            'User-Agent':
                'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) ' +
                'AppleWebKit/537.36 (KHTML, like Gecko) ' +
                'Chrome/120.0.0.0 Safari/537.36',
        };
    }

    async searchListings(category, options = {}) {
        const {
            query = '',
            minPrice = null,
            maxPrice = null,
            hasPic = false,
            maxPages = 5,
        } = options;

        const allListings = [];

        for (let page = 0; page < maxPages; page++) {
            const offset = page * 120;
            const url = this.buildSearchUrl(
                category, query, minPrice, maxPrice, hasPic, offset
            );

            console.log(`Fetching page ${page + 1}: ${url}`);
            const listings = await this.fetchSearchPage(url);

            if (listings.length === 0) break;
            allListings.push(...listings);

            // Respectful delay between pages
            await this.delay(2000 + Math.random() * 2000);
        }

        return allListings;
    }

    buildSearchUrl(category, query, minPrice, maxPrice, hasPic, offset) {
        const params = new URLSearchParams();
        if (query) params.set('query', query);
        if (minPrice) params.set('min_price', minPrice);
        if (maxPrice) params.set('max_price', maxPrice);
        if (hasPic) params.set('hasPic', '1');
        if (offset > 0) params.set('s', offset);

        return `${this.baseUrl}/search/${category}?${params.toString()}`;
    }

    async fetchSearchPage(url) {
        try {
            const response = await axios.get(url, { headers: this.headers });
            const $ = cheerio.load(response.data);
            const listings = [];

            $('li.cl-static-search-result, .result-row').each((i, el) => {

Multi-City Scraping: Covering Geographic Markets

One of Craigslist's biggest data advantages is its geographic coverage. Here's how to scrape across multiple cities efficiently:

MAJOR_CITIES = [
    "newyork", "losangeles", "chicago", "sfbay", "seattle",

Scaling with Apify for Production Workloads

For production-grade Craigslist scraping — thousands of listings across dozens of cities, running on a schedule — you need cloud infrastructure. Apify makes this straightforward:

Building a Craigslist Apify Actor

const Apify = require('apify');
const cheerio = require('cheerio');

Apify.main(async () => {
    const input = await Apify.getInput();
    const {
        cities = ['sfbay'],

        query = '',
        minPrice = null,
        maxPrice = null,
        maxPagesPerCity = 3,
    } = input;

    const requestQueue = await Apify.openRequestQueue();
    const dataset = await Apify.openDataset();

    // Queue search pages for each city
    for (const city of cities) {
        const baseUrl = `https://${city}.craigslist.org/search/${category}`;
        const params = new URLSearchParams();
        if (query) params.set('query', query);
        if (minPrice) params.set('min_price', minPrice);
        if (maxPrice) params.set('max_price', maxPrice);

        for (let page = 0; page < maxPagesPerCity; page++) {
            params.set('s', page * 120);
            await requestQueue.addRequest({

Scheduling and Monitoring

With Apify, you can schedule your Craigslist scraper to run daily, tracking new listings and price changes over time:

from apify_client import ApifyClient


def schedule_craigslist_monitor(api_token: str):
    """Set up scheduled Craigslist monitoring."""
    client = ApifyClient(api_token)

    # Configure the actor to run daily
    schedule = client.schedules().create(
        name="craigslist-daily-monitor",
        cron_expression="0 8 * * *",  # 8 AM daily
        actions=[{
            "type": "RUN_ACTOR",
            "actorId": "your-username/craigslist-scraper",
            "runInput": {
                "cities": [
                    "sfbay", "newyork", "losangeles",
                    "seattle", "austin",
                ],
                "category": "apa",
                "maxPagesPerCity": 5,
            },
        }],
    )

Handling Craigslist-Specific Challenges

Contact Information Patterns

Craigslist anonymizes contact info through relay emails. The reply link format is:

Enter fullscreen mode Exit fullscreen mode

Some sellers include phone numbers in the listing body. Here's how to extract them:

import re


def extract_contact_info(description: str) -> dict:
    """Extract phone numbers and emails from listing text."""
    contacts = {"phones": [], "emails": []}

    # Phone patterns
    phone_patterns = [
        r'\b(\d{3})[-.\s]?(\d{3})[-.\s]?(\d{4})\b',
        r'\((\d{3})\)\s?(\d{3})[-.\s]?(\d{4})',
    ]

    for pattern in phone_patterns:
        matches = re.findall(pattern, description)
        for match in matches:
            phone = "".join(match)
            if len(phone) == 10:
                contacts["phones"].append(
                    f"({phone[:3]}) {phone[3:6]}-{phone[6:]}"
                )

    # Email patterns (non-Craigslist relay)
    email_pattern = r'[\w.+-]+@[\w-]+\.[\w.-]+'
    emails = re.findall(email_pattern, description)
    contacts["emails"] = [
        e for e in emails if "craigslist.org" not in e
    ]

    return contacts
Enter fullscreen mode Exit fullscreen mode

Dealing with Expired Listings

Craigslist listings expire quickly — typically within 7-45 days depending on the category. Build your scraper to handle 404s gracefully and timestamp everything:

async function fetchWithExpiredHandling(url) {
    try {
        const response = await axios.get(url, {
            validateStatus: (status) => status < 500,
        });

        if (response.status === 404) {
            return { expired: true, url };
        }

        if (response.status === 403) {
            console.log('Rate limited, backing off...');
            await delay(10000);
            return { rateLimited: true, url };
        }

        return { data: response.data, url };
    } catch (error) {
        return { error: error.message, url };
    }
}
Enter fullscreen mode Exit fullscreen mode

Geographic Deduplication

Craigslist users often post the same listing in multiple nearby cities. Detect duplicates by comparing title + price + description hash:

import hashlib


def generate_listing_fingerprint(listing: dict) -> str:
    """Create a fingerprint for deduplication."""
    content = (
        listing.get("title", "").lower().strip()
        + str(listing.get("price", ""))
        + listing.get("description", "")[:200].lower().strip()
    )
    return hashlib.md5(content.encode()).hexdigest()


def deduplicate_listings(listings: list[dict]) -> list[dict]:
    """Remove duplicate listings posted across multiple cities."""
    seen = set()
    unique = []

    for listing in listings:
        fp = generate_listing_fingerprint(listing)
        if fp not in seen:
            seen.add(fp)
            unique.append(listing)

    removed = len(listings) - len(unique)
    print(f"Removed {removed} duplicates from {len(listings)} listings")
    return unique
Enter fullscreen mode Exit fullscreen mode

Real-World Use Cases

Real Estate Market Analysis

Track rental prices across neighborhoods over time to identify trends, underpriced areas, or market shifts. This data is invaluable for real estate investors and property managers.

Vehicle Market Research

Monitor used car prices by make, model, and year to find deals or understand depreciation curves. Dealerships use this data to price their inventory competitively.

Job Market Intelligence

Scrape job listings to track which skills are in demand, what companies are hiring, and how salary ranges vary by city.

Academic Research

Researchers study Craigslist data for everything from housing discrimination patterns to local economic indicators.


Ethical Guidelines and Legal Considerations

  1. Respect robots.txt: Always check the site's robots.txt before scraping
  2. Rate limiting: Keep requests slow — 1-2 per second maximum. Craigslist actively blocks aggressive scrapers
  3. No personal data harvesting: Don't collect or store personal contact information in bulk
  4. Terms of service: Review Craigslist's ToS regarding automated access
  5. Data retention: Don't store data longer than needed for your analysis
  6. No republishing raw listings: Craigslist actively litigates against sites that republish their content

Conclusion

Craigslist's simple HTML structure makes it technically straightforward to scrape, but its geographic scale and data volume create real engineering challenges. By combining efficient parsing (Cheerio/BeautifulSoup for search pages) with cloud-based infrastructure (Apify for scale and scheduling), you can build comprehensive datasets covering local markets nationwide.

The key to successful Craigslist scraping is respecting rate limits, handling the geographic subdomain structure intelligently, and deduplicating across cities. Whether you're analyzing rental markets, tracking vehicle prices, or monitoring job postings, the techniques in this guide provide a solid foundation for extracting actionable data from the world's largest classifieds platform.

Start with a single city and category, validate your extraction pipeline, then scale horizontally across Craigslist's 400+ metro areas using Apify's cloud infrastructure.
