How to Research Zoning

Steps that catch most issues:

1. Pull the parcel's current zoning from the county or city GIS portal.
2. Read the zoning ordinance for that district — not the summary, the actual code.
3. Confirm permitted uses, conditional uses, minimum lot size, setbacks, frontage, and density.
4. Check for overlays: flood, historic, hillside, airport, agricultural protection.
5. Call the planner. A 10-minute call can save 10 months of entitlement.

Zoning sets the ceiling; the site decides what fits under it. Once the district rules are clear, test them against whether the land is buildable, and if density is the thesis, check the frontage and lot-size math in the 1–4 lot split overview. Pull the district and overlay layers from your county GIS research rather than the listing.

Save everything to Knowledge: the planner's name, the code section, the date, and a link to the ordinance. Code changes. Your notes need a verified date.
