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

Yes. The Town of Keenesburg zones the land inside its limits under Chapter 16 of its municipal code, and no building, structure or land may be used unless it conforms to the regulations for its zone2. Any use not specifically permitted in a zone is prohibited there2.

Living in an RV is tightly limited. The code bars using an RV for living, sleeping, housekeeping or food preparation on a public right-of-way or on private property in town9. The exception is a guest stay on residential property of up to 7 consecutive days, once per 12 months per vehicle, extendable by up to 7 more days on written request9. The RV must sit at least 3 feet back from the sidewalk or front property line9. A resident may park, but not live in, one RV on single- or two-family property9.

We could not confirm Keenesburg's rules for tiny homes, accessory dwellings, minimum lot sizes or setbacks by zone district. Ask the Town's Planning Department11 before buying.

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

Yes. No building or work on a building may start inside Keenesburg without a building permit1. The Town has adopted the 2018 International Building Code with Town amendments6, and a list of exempt work comes from the amended code1.

The Town's Building Official, a contracted building department, issues or denies building permits5. Reach the Town's Building Department at 303-732-4281 x2 or [email protected]12. A permit is issued only if the site conforms to zoning, has legal access and is connected to water and wastewater1, and only if the building site has not been divided except with Board of Trustees approval13.

We could not confirm the Town's permit fees, which the code ties to a Town Fee Schedule, or whether owner-builders have a special route. Ask the Building Department.

How do septic permits work inside Keenesburg?

Septic is the hardest part of building in Keenesburg. The code states that all occupied structures within the town must be connected to the public sewer system8. A private septic system is allowed only with written approval from the Board of Trustees, and only when the occupied structure is more than 400 feet from any public sewer main and connecting is impractical because of terrain, highways or railroad rights-of-way14.

If approved, the septic permit application is filed with the Town and duplicated to the Weld County Department of Health4. The permit does not take effect until the installation has been inspected by both the county health department and the Town7. Weld County's own policy likewise favors public sewer wherever feasible15. Call Weld County Environmental Health Services at (970) 400-641515.

What are the steps to build a home in Keenesburg, in order?

  1. Confirm the zone and allowed uses with the Planning Department112.
  2. Confirm legal access to a public street or a private street connecting to one16.
  3. Ask about public water and sewer connection, since occupied structures must connect to the public sewer8.
  4. If the site lies in a flood hazard area, plan for a floodplain development permit10.
  5. Apply for a building permit through the Building Department121.
  6. Only if sewer is unavailable, seek Board of Trustees approval and file the septic application with the Town and Weld County414.

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

Land outside Keenesburg town limits is governed by Weld County, not the Town. Unincorporated Weld County has its own building permit and zoning rules, and its own RV limits, so the Town's answers above do not carry over; see the Weld County page.

Septic inspection stays partly with Weld County's health department7. For wells, we could not confirm whether the Town allows private wells; Colorado's Division of Water Resources issues well permits on Weld County parcels17. Weld County's effective property tax rate is 0.5%18.

Watch-outs

  • Septic is the exception in Keenesburg: private systems need written Board of Trustees approval and are tied to a 400-foot distance from the sewer main14.
  • Do not rely on Weld County's unincorporated-area RV or building rules inside town limits; Keenesburg's own code controls there9.
  • We could not confirm Keenesburg's zone-by-zone lot sizes, setbacks, tiny home or accessory dwelling rules, or permit fees; ask the Planning and Building Departments1112.
