Scrape notes: All three source URLs returned HTTP 403 from Cloudflare with no permit content. The fetched payloads contain only Cloudflare block messages, so no requirements, fees, timelines, exceptions, license rules, application URLs, or contact info could be extracted. Every field is null or empty. Re-fetch is needed with a method that bypasses the Cloudflare challenge (for example a headless browser with cookies enabled, or an alternate canonical source such as the City of Houston Public Works pages or the Houston Code of Ordinances Chapter 9 plumbing sections).
