When a deed near Dacono says lot and block, the Northglenn plat map is where those numbers come from. This Northglenn guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
Who keeps the Northglenn plat map
For land around Fort Lupton, look for the plat book reference on the parcel record; use it to request a copy.
Where the parcel data lives
Go first to the Weld County parcel viewer; it includes each tax parcel in the county, Fort Lupton included. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, which applies near Erie as much as anywhere. For acreage around Erie, the record panel typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Next door to Weld County
Weld County borders Adams County, Boulder County, Broomfield County, Larimer County, and Logan County, and each of those keeps its own parcel map. Ground near Fort Lupton that runs to the line may be split in two county records, so check the adjacent map before you assume the acreage. For a home near Frederick, our state page lists each neighboring county map for Colorado.
When a plat changes
An amended plat may change lots around Dacono, search the index for replats of the same subdivision; street vacations near Brighton show up in the records too.
Northglenn and the county around it
Northglenn is part of Weld County, Colorado, which means parcel data comes from the county. If you're looking near Thornton, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits toward Thornton usually falls under county rules, not municipal ones.
How land is described here
Colorado is laid out under the Public Land Survey System, so rural legal descriptions near Brighton cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Fort Lupton can be irregular. Keep the legal description for land near Frederick when you talk to a surveyor.
How a plat differs from the tax map
The Weld County parcel viewer draws parcels for taxes, but the recorded plat is what the deed relies on.
Getting your bearings
Greeley holds the county offices, where most land records are kept. Other places on the map include Thornton, Erie, Brighton, and Dacono, each with its own cluster of lots. Roughly 359,442 people call Weld County home (Census estimate, 2023) on roughly 3,985 square miles. Weld County was formed in 1861, and some chains of title near Dacono are long. Places such as Pawnee National Grassland help you orient on the aerial around Brighton.
A word on accuracy
The acreage figure is an estimate; only a licensed surveyor establishes the real corners on land around Thornton. For acreage around Thornton, records update in batches, so a deed recorded last month might lag behind.
Recorded documents worth pulling
For anything that matters, get the recorded deed from the County Clerk and Recorder; the parcel map near Brighton only summarizes it. Inherited tracts around Brighton can go back through a long string of deeds, so a title company earns its fee if money is changing hands.
Lots, blocks and easements
For acreage around Brighton, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Which office to call
Deeds, mortgages and recorded plats for land near Fort Lupton are with the County Clerk and Recorder, often with an online index. Zoning, permits and septic questions near Brighton are for the local planning and health departments, depending on whether the land is inside town limits.
Ordering the Northglenn plat map
Around Brighton, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Dacono, though signal can drop in rural spots. A printout of the tract near Brighton is a good backup.
When there's no plat
Acreage around Dacono outside a subdivision is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
