Why use the official docs?
Zoned reads public open data and summarizes it in plain English. That’s a great place to start, but by-laws change, amendments happen, site-specific conditions apply, and only the city is authoritative. Before committing to a design, a contractor agreement, a purchase offer, or a permit application, you should confirm the zoning, setback, coverage, height, and any overlays directly on the city’s own site. For the full scope of what Zoned is and is not, see our Disclaimer and Terms of Use.
