Ahead of any building plan near Wauwatosa, check the Hales Corners zoning map early: the zoning district decides setbacks, lot size and uses. What this Hales Corners guide covers: which office sets the rules for a lot, matching a lot to its zoning district, and when a variance or rezoning comes up.
Which office controls the Hales Corners zoning map
Inside town or city limits, zoning usually comes from the municipality, which means a parcel in this town is governed there around South Milwaukee. Outside those limits, near Greendale or West Milwaukee, the county may have its own zoning, or none at all; ask the county planning office to be sure. A fast way to settle it: ask whether the parcel near Oak Creek is inside the boundary.
The viewer Milwaukee County publishes
Your first stop is the Milwaukee County parcel viewer; it maps each assessed parcel in the county, Oak Creek included. For a tract near West Milwaukee, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. On ground around Oak Creek, write down the parcel ID before closing the panel; every records desk in the county will want it.
Questions for the planning office

Getting answers from the right desk
