Before you buy a lot near Bar Nunn with a plan in mind, check the Casper zoning map before anything else: a district label decides setbacks, lot size and uses. This Casper guide covers: who controls zoning for a given parcel, how to match a parcel to its district, and when a variance or rezoning comes up.
Which office controls the Casper zoning map
Inside town or city limits, zoning usually comes from the municipality, so property inside Casper is governed there. Past the city line, around Mills, the county's ordinance, if any, takes over; the county planning or zoning office can confirm. A fast way to settle it: check the municipal limits layer on the Natrona County ArcGIS parcel map.
Opening the official parcel viewer
Begin with the Natrona County ArcGIS parcel map; it maps every tax parcel in the county, Bar Nunn included. For a home near Midwest, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Bar Nunn, a pop-up or side panel typically gives the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
What to ask before you buy
Have the parcel ID ready and describe the plan for the lot near Midwest; staff can point to the right section of the ordinance. Also ask whether the lot near Mills is a legal lot of record, because nonconforming lots can carry limits.
A quick look at the area
Casper holds the county offices, which is where the courthouse records live. You'll also find Mills, Evansville, Bar Nunn, and Edgerton, where town lots give way to larger tracts. Roughly 79,941 people live in Natrona County (Census estimate, 2023) across roughly 5,341 square miles. Features like Medicine Bow National Forest are easy to spot when you zoom out from Bar Nunn.
Reading the legal description

A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Bar Nunn vary in size. Write down the legal description for the tract near Midwest for any title or survey request.
Casper, WY: the basics
Casper sits in Natrona County, Wyoming, so its parcels are on the county's map. Casper is also the county seat, so deeds and plats are filed in town. In and around Evansville, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits near Bar Nunn often answers to county rules rather than the town's.
Who handles what
Deeds, mortgages and recorded plats for land near Edgerton are with the County Clerk, often with an online index. Questions about what you can build around Bar Nunn are for the local planning and health departments, depending on whether the land is inside town limits.
Building permits and inspections
Even when zoning allows a use near Midwest, you still need building permits and inspections; septic or sewer and driveway access are often reviewed too.
How to look up the district
Start by finding the parcel on the Natrona County ArcGIS parcel map, note the parcel number, and match it to the adopted zoning map. For a home near Bar Nunn, labels such as R-1, B-2 or AG stand for residential, commercial or agricultural districts; the letters vary from place to place.
Backing up the map with records
Before you sign anything, pull the recorded deed from the County Clerk; the parcel map near Bar Nunn only summarizes it. Long-held tracts around Bar Nunn can trace back through a long string of deeds, so a title company is worth hiring if money is changing hands.
Setbacks, lot size and uses
If the land is near Evansville, each district lists what's allowed outright and what needs approval. If the land is near Evansville, overlay districts, such as floodplain, historic or airport zones, can add rules on top of the base district.
When a plan doesn't fit
If you're looking near Midwest, expect an application, a fee, notice to neighbors and a public hearing.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Midwest, though signal can drop in rural spots. A saved image of the lot near Bar Nunn and its lines keeps working without signal.
Limits of the parcel data
Listed acreage is an estimate; only a licensed surveyor can set the real lines on land around Edgerton. If the land is near Bar Nunn, records update in batches, so a deed recorded last month might lag behind.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
