Land and property
Zoning, buildability, and Colorado's 35-acre issue
Why parcel size alone does not answer whether you can build, and the local checks for zoning, access, water, septic, fire, flood, utilities, and permits.
Who gives the final answer?
Use the right person for each part
County or municipal planning office
This is the first stop for zoning, subdivision status, allowed uses, lot standards, and the right permit path.
Choose a countyBuilding, fire, and public-health offices
These offices address building codes, access, fire review, septic, and other permits for the exact project.
Water provider or DWR
A build plan needs a lawful and workable water source. Use the provider or DWR for the actual record and limits.
Open DWRSurvey, title, design, and legal professionals
Use the right professional when the answer depends on a boundary, easement, covenant, engineered system, or legal interpretation.
The key distinction
Subdivision status and buildability are different questions
Thirty-five acres may change which subdivision review applies. It does not decide whether a home, driveway, well, septic system, business, rental, or second dwelling is allowed or workable on the parcel.
Ask the local office about the whole plan
Use and zoning
Describe the home, outbuilding, animals, business, rental, or other use you want. Ask whether it is allowed and what review comes next.
Lot and access
Ask about legal lot status, frontage, road standards, driveway access, emergency access, and recorded easements.
Water and septic
Confirm the actual water path and the local septic-review path. Parcel size and nearby homes do not settle either one.
Site limits
Ask about wildfire review, floodplain, steep slopes, geologic hazards, utilities, setbacks, and any overlay district.
Get an answer you can use
- Give the office the parcel number, legal description, address if one exists, and a plain description of the plan.
- Ask which jurisdiction controls the parcel. A mailing address may not match city limits.
- Ask which answer is only general guidance and which step creates an official approval.
- Keep the written answer, map, code section, application list, and contact name with your due-diligence file.
Take this with you
Before you call a parcel buildable
- 1 Correct planning and building jurisdiction is confirmed.
- 2 Zoning and the exact planned use are discussed.
- 3 Legal lot, boundary, and access questions are settled.
- 4 Water and septic paths are confirmed.
- 5 Fire, flood, slope, utility, and road limits are checked.
- 6 You know which permit or written approval gives the final answer.

Check the current record before you act
Use these links to find the office, form, record, or rule that controls this part of the property.
Use this carefully: A parcel's acreage, listing, assessor record, tax classification, or nearby development does not approve a project. The controlling local office, current code, recorded documents, and issued permits decide what can move forward.
