Do you need a building permit in Town of Lochbuie, CO?

Lochbuie requires building permits for new construction, additions, basement finishes, garages and pole barns, among other projects.1 Residential buildings in Lochbuie are governed by the town’s adopted 2018 International Residential Code, with town amendments.10

A Lochbuie building-permit application may require plans, setbacks, construction details and approvals from building, planning, public works and fire staff.11 Changes to approved plans or layout require approval before the changes are made, and changes in use or occupancy also require approval before proceeding.11

Who issues building permits in Town of Lochbuie?

The Town of Lochbuie Community Development Department is responsible for land use, planning, building permits and inspections.12 Residents can apply online through the CommunityConnect link on the town’s Building Permits and Inspections page.1 For application questions, contact the town Building Department using the contact listed above; for land-use questions, contact Community Development.112

Keep septic approval separate from the town building application: Weld County Public Health and Environment handles septic permitting for the Weld County portion of Lochbuie.3

Does Town of Lochbuie have zoning, lot sizes and setbacks?

Lochbuie’s land-use regulations apply throughout town limits, and a land use requiring town approval must receive that approval before the activity begins.2 Lochbuie R-1 lots require at least 5,200 square feet per dwelling unit, while Agricultural District lots require at least 5 acres.78

In Lochbuie’s Agricultural District, the minimum front yard is 50 feet, the side yard is 20 feet, and the rear yard is 10 feet; the side yard on corner lots is 50 feet.13 Ask Community Development to identify the parcel’s district before applying those standards to a purchase or site plan.12

How do septic permits work inside Town of Lochbuie?

For the Weld County portion of Lochbuie, a new, repaired, upgraded, reconnected or vault on-site wastewater treatment system needs Weld County approval.3 The application requires the appropriate fee, site and soils evaluation, design documents, parcel information and other supporting materials; vaults are allowed only in specific circumstances.3

Weld County inspects the site before issuing the septic permit, so mark the site and stake or flag the well or cistern, absorption system and soil tests.14 Weld County limits on-site wastewater systems to areas where public sewer is not feasible, so sewer availability belongs in the early discussion with the town and county health office.15

Can you live in an RV or tiny home in Town of Lochbuie?

We could not confirm a Lochbuie rule allowing RV occupancy on a private lot, including temporary occupancy while building; ask Community Development about the proposed use before relying on an RV as housing.12 We also could not confirm a separate town tiny-home occupancy rule; Lochbuie’s district floor-area standards still matter for a proposed dwelling.45

Lochbuie R-1 single-family dwellings require at least 750 square feet, and RR principal dwellings require at least 840 square feet.45 R-1 includes manufactured homes on individual lots subject to applicable standards, but the town separately prohibits mobile homes as defined by its code.9

Building a home in Town of Lochbuie: what are the steps?

  1. Ask Lochbuie Community Development to identify the zoning district and any required land-use approval before establishing the use.122
  2. Resolve wastewater service; if the Weld County parcel needs septic, submit the county application, soils evaluation and design materials and arrange the site inspection.314
  3. Submit the town building application with the required plans and project details, using the town’s online application route.111
  4. Call for inspections at the required construction stages, giving the building inspector at least 1 day’s notice.16
  5. Obtain approval before changing the plans, layout, use or occupancy.11

What should you check before buying land in Town of Lochbuie?

Ask Lochbuie Community Development about utility service, driveway approval, current building-permit fees, owner-builder requirements and the approval needed before moving into the completed home; we could not confirm complete town requirements for these questions.12 If the property has septic, ask Weld County Public Health and Environment for the septic permit and installation inspection records.17

For a proposed private well, Colorado Division of Water Resources provides well-permit applications for new or replacement wells and registration forms for existing wells.18 For land outside Lochbuie town limits, use the Weld County guide: the county’s residential building rules apply to unincorporated land.19

Watch-outs

  • Lochbuie building permits become void if construction does not begin within 180 days or work stops for 180 continuous days; building permits are not transferable.11
  • We could not confirm permission for composting toilets or other off-grid sanitation inside Lochbuie; ask Community Development and, for a Weld County septic proposal, Environmental Health Services before designing the system.1217
