Rules in the bylaw's general sections (parking, fences, suites, home businesses) also apply, and a lot can have site-specific rules. Schedule A of the bylaw is the text; Schedule B (the zoning map) is a separate PDF at https://houston.civicweb.net/document/149524. The document shows "Updated - N/A". Zone pages are taken from the bylaw text by a research agent and have not yet been reviewed by a person: confirm with the bylaw before you rely on them. How answers are checked.
