- Prohibition on using automated tools to access Zillow
- Restriction on systematically downloading content
- Prohibition on circumventing security measures
- Restriction on using Zillow data for commercial purposes without authorization
- Specific prohibition on scraping for real estate lead generation without partnership
Legal Precedents
Recent court rulings have limited platforms' ability to use the CFAA against scrapers of public data:
- hiQ v. LinkedIn: Scraping public data does not violate CFAA
- Meta v. Bright Data: Public data scraping is legally permissible
- Van Buren v. US: Terms of Service violations are not CFAA violations
However, Zillow can still pursue civil claims for breach of contract.
Data Protection
Real estate data raises specific privacy concerns:
- Property addresses are public record but combined data may be sensitive
- Owner information may be personally identifiable
- Photos of properties may have privacy implications
- GDPR and CCPA may apply to processed real estate data
FAQ
Can I legally scrape Zillow data for Burbank and Pomona listings?
The legal landscape is evolving. Recent precedents suggest scraping publicly accessible data may not violate federal law, but Zillow's Terms of Use prohibit it. The safest approach is using the official Zillow API or managed services that assume compliance responsibility.
How do I compare Burbank and Pomona real estate markets using Zillow data?
Key metrics for comparison: median listing prices, price per square foot, days on market, inventory levels, price reduction frequency, and sales-to-list price ratios. Collect data from both markets and calculate these metrics for side-by-side analysis.
What is the difference between Zillow API and scraping?
The Zillow API is fully compliant but expensive and limited in data fields. Scraping provides comprehensive data (price history, tax records, all photos) at lower cost but operates in a legal gray area and requires anti-detection infrastructure.
How often should I refresh Zillow data for Burbank and Pomona?
For active markets like Burbank and Pomona, daily updates are recommended for active listings. Sold data can be updated weekly. Price changes and status updates should be monitored in real-time for time-sensitive applications.
Can I get historical Zillow data for trend analysis?
The Zillow API provides limited historical data. Scraping can capture historical listings if collected over time. Some third-party services maintain historical databases. CoreClaw can provide historical trend data as part of managed services.
What data should I collect for real estate investment analysis?
Essential data: listing price, property details (beds, baths, sqft), days on market, price history, comparable sales, neighborhood statistics, and rental estimates. Tax history and mortgage estimates provide additional investment context.
