Does Hudson, Colorado have zoning, and what does it mean for tiny homes and RVs?

Yes. The Town of Hudson zones land inside its limits through its Land Development Code, and a use that is not listed in the permitted use table is not permitted unless the planning director finds it similar to a listed use1. A blank cell in the table means the use is not allowed in that district1.

A tiny house may be an accessory dwelling unit in Hudson as a conditional use, and the ADU standards in section 16-62(g)(2) of the town code apply4. Camping on private property inside Hudson is unlawful without the consent of the owner or authorized agent5, so living in an RV on a lot is not something to assume; ask the Town's planning staff before you try it. We have not confirmed Hudson's minimum lot sizes, setbacks or dwelling-size rules by district.

Do you need a building permit in Hudson, and who issues it?

Building permits inside Hudson come from the Town of Hudson, not Weld County. The Town applies the 2018 edition of the ICC codes2, with local amendments in the Hudson Municipal Code. No work may begin until the permit is issued by Town Hall2.

The Town runs an online permit portal (CommunityCore) for applications and inspection requests, and lists its permit fees on its Permits & Licenses page. We could not confirm Hudson's owner-builder rules or fee amounts, so call the Town at 303-536-93112 before you pull plans.

How do septic permits work inside Hudson?

We could not confirm who issues septic permits for lots inside Hudson town limits. Weld County Environmental Health Services runs the septic permit program for the county, and its stated policy is to require public sewer where feasible and to limit on-site systems to areas where sewer is not feasible3. Ask the town whether your lot has sewer service, and call Weld County at (970) 400-6415 to check for a septic permit on file3.

What stays with Weld County, and what should you check before you buy?

Weld County's rules for unincorporated land, including its building permits, zoning and RV rules, do not apply inside Hudson. For land outside town limits, see the Weld County page. Weld County's effective property tax rate is 0.5%6, and the median property tax bill is $2,242 a year7. Confirm water, sewer, wells and the zoning district of your exact parcel with the Town before closing; we could not verify those rules for Hudson.

Watch-outs

  • Hudson's own rules, not Weld County's, govern building and zoning on lots inside town limits1.
  • Septic and well rules inside Hudson are unconfirmed; ask Weld County Environmental Health Services at (970) 400-64153.
