Ahead of any building plan near Berthoud, look at the Longmont zoning map before anything else: the zoning district can make or break the plan. What this Longmont guide covers: who controls zoning for a given parcel, how to match a parcel to its district, and what to ask the planning staff.
Getting started with the Longmont zoning map
Inside town or city limits, the local government adopts its own zoning map, so property inside Longmont answers to that map. Past the city line, around Firestone, 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 Berthoud is inside the boundary.
The viewer Weld County publishes
Your first stop is the Weld County parcel viewer; it covers each assessed parcel in the county, Firestone included. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, which applies near Mead as much as anywhere. With a lot near Firestone, the parcel card usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Getting your bearings
Greeley is the county seat, which is where the courthouse records live. Other places on the map include Mead, Frederick, Firestone, and Erie, each with its own cluster of lots. About 359,442 people call Weld County home (Census Bureau estimate, 2023) spread over roughly 3,985 square miles. Weld County dates to 1861, and some chains of title near Mead are long. Features like Pawnee National Grassland are easy to spot when you zoom out from Firestone.
Longmont, CO: the basics
Longmont sits in Weld County, Colorado, so its parcels are on the county's map. For a tract near Berthoud, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the city limits near Firestone often falls under county rules, not municipal ones.
When a parcel crosses a boundary
Weld County borders Adams County, Boulder County, Broomfield County, Larimer County, and Logan County, all with their own assessor records. Acreage along the edge near Firestone can show up in two county records, so check the neighboring map as well. Out toward Frederick, the Platbookmapper state page lists each bordering county map across Colorado.
Recorded documents worth pulling
Before you sign anything, pull the recorded deed from the County Clerk and Recorder; the parcel map near Mead only summarizes it. For a home near Berthoud, have ready the document number listed on the parcel record and the lookup takes minutes.
Finding a parcel's zoning district
Look up the lot on the Weld County parcel viewer first, note the parcel number, then compare it to the zoning map from the office covering Longmont. In and around Frederick, district codes like R-1, C-2 or A-1 point to a table of rules in the ordinance; the letters vary from place to place.
Calling planning staff
When you call about land near Berthoud, give the parcel number and your intended use; ask what's allowed by right and what needs a permit. Ask whether a parcel near Mead meets current minimum size, since some older splits don't.
Zoning is only step one
Even when zoning allows a use near Mead, you still need building permits and inspections; health and road departments may weigh in on land near Erie.
Which office to call
For assessment questions about property around Firestone are handled by the County Assessor, the office behind the parcel record. Questions about what you can build around Firestone go to planning, building or health offices, town or county, depending on location.
Rules tied to a district
With a lot near Berthoud, the ordinance spells out what's allowed outright and what needs approval. For a home near Firestone, overlays, whether historic, floodplain or corridor, can add rules on top of the base district.
How land is described here
Colorado is laid out under the Public Land Survey System, so rural legal descriptions near Frederick cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Berthoud odd-sized. Copy the legal description from the record for the parcel near Berthoud before you request a deed or survey.
Asking for an exception
In and around Erie, most of these involve time, so budget weeks or months before you close.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Firestone, but coverage can be spotty out of town. A printout of the tract near Mead keeps working without signal.
Quick answers
