Before you buy a lot near Waskom with a plan in mind, pull up the Longview zoning map early: the zoning district decides setbacks, lot size and uses. In this Longview guide: who controls zoning for a given parcel, matching a lot to its zoning district, and the questions that save a wasted trip.
Which office controls the Longview zoning map
Within municipal limits, the town or city normally writes the zoning code, so property inside Longview is governed there. Outside those limits, near Marshall or Hallsville, county rules apply where they exist; ask the county planning office to be sure. The quickest way to tell which applies: check the municipal limits layer on the Texas county CAD map.
The free map to start with
Your first stop is the Texas county CAD map; it covers each assessed parcel around Uncertain and Scottsville. If the land is near Uncertain, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. If you're looking near Marshall, write down the parcel ID from that panel; each records desk in the county asks for it first.
Land on the county line
Harrison County borders Caddo Parish, LA, Gregg County, Marion County, Panola County, and Rusk County; every one of them runs a separate parcel map. A tract near the line by Scottsville can show up across two assessors' files, so look at the adjacent map as well. For a parcel near Scottsville, our state page lists each bordering county map for Texas.
Calling planning staff
When you call about land near Marshall, give the parcel number and your intended use; ask what's allowed by right and what needs a permit. Ask whether a parcel near Waskom meets current minimum size, since some older splits don't.
Where Longview fits in
Longview lies within Harrison County, Texas, which means parcel data comes from the county. Near Hallsville, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Acreage past the town limits near Uncertain generally answers to county rules, not municipal ones.
Matching a lot to the Longview zoning map
Pull the parcel up on the Texas county CAD map, note the parcel number, then compare it to the zoning map from the office covering Longview. District codes like R-1, C-2 or A-1 aren't self-explanatory, so read the ordinance chapter for each; codes near Scottsville may differ from the next town's.
Reading the ordinance
For a building plan near Waskom, look up setbacks, height and how much of the lot can be covered. For a tract near Waskom, overlay districts, whether historic, floodplain or corridor, can add rules on top of the base district.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Marshall, but coverage can be spotty out of town. A screenshot of the parcel near Waskom with its ID keeps working without signal.
Zoning is only step one
Even when zoning allows a use near Marshall, a building permit is a separate step; health and road departments may weigh in on land near Scottsville.
When a plan doesn't fit
Around Marshall, most of these involve time, so budget weeks or months before you close.
Places you'll see on the map
Marshall is the county seat, which is where the courthouse records live. You'll also find Hallsville, Scottsville, and Uncertain. Around 70,895 people call Harrison County home (Census Bureau estimate, 2023) spread over about 900 square miles. Harrison County was organized in 1842, and some chains of title near Uncertain are long. Features like Caddo Lake National Wildlife Refuge make handy reference points on the map near Uncertain.
Reading the legal description
Older tracts around Waskom commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Subdivision lots in Marshall are typically described by lot and block, which is simpler to follow. Keep the legal description for land near Waskom before you request a deed or survey.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so a tree line near Waskom can sit several feet off the line on screen. Near Waskom, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Offices that can help
For assessment questions about property around Uncertain are handled by the appraisal district, the office behind the parcel record. Questions about what you can build around Marshall go to planning, building or health offices, depending on whether the land is inside town limits.
