Overview: Are STRs allowed in Conifer?

Short-term rentals are conditionally allowed in unincorporated Jefferson County, which includes Conifer. STRs are considered a residential use and require a two-step approval process: (1) a Special Exception from the Jefferson County Board of Adjustment (BOA), followed by (2) a Short-Term Rental Permit issued by Planning & Zoning. Properties must meet eligibility criteria including a minimum lot size of one acre, compliance with the underlying zoning standards, adequate parking, defensible space requirements, valid water and sanitation, legal access, use of the primary dwelling, and no more than five bedrooms. The BOA approval is a temporary permit and does not “run with the land.” The process from application to BOA decision typically takes about two months; initial permits are valid for six months, then renew annually.

Note: Jefferson County has proposed comprehensive updates to its STR regulations intended to simplify approvals and improve compliance. As of this guide’s date (2025), investors should verify whether those updates have been adopted and are in effect, as they may remove lot-size limits, change the approval pathway, and alter fee structures.

How to Start an STR Business in Conifer (Process Overview)

• Confirm eligibility: Verify your property meets the minimum one-acre lot size, is a residential dwelling, has adequate parking, meets Wildfire Hazard Overlay/defensible space requirements, has valid water and sanitation (e.g., well/septic), legal access, and contains no more than five bedrooms.
• Step 1 — Board of Adjustment Special Exception: Prepare and submit a Special Exception application to the BOA. A public hearing is required. Approval timelines are typically about two months from submission.
• Step 2 — STR Permit with Planning & Zoning: After BOA approval, apply for the Short-Term Rental Permit with Planning & Zoning. Permits are initially valid for six months; thereafter renew annually.
• Compliance and operations: Maintain defensible space, meet parking standards, ensure sanitation/water validity, and avoid code violations. The county is ramping up enforcement and compliance monitoring, including the use of third-party identification services and complaint hotlines.
• Ongoing obligations: Comply with county conditions and any BOA-imposed requirements; renew per schedule; monitor for proposed regulation changes that may streamline or adjust the process.

Required Documents, Permits, Licenses, and Guidelines

• Special Exception application to the Board of Adjustment (Zoning Resolution Section 11 governs BOA procedures and criteria).
• Short-Term Rental Permit application to Planning & Zoning (Zoning Resolution Section 2 outlines general requirements).
• Site plan showing building footprint, parking, access, and compliance with underlying zoning.
• Proof of water and sanitation (e.g., well permit, septic inspection or permit).
• Defensible space documentation (Wildfire Hazard Overlay compliance).
• Proof of legal access (e.g., recorded easement, public road access).
• Evidence the STR will use the primary dwelling unit (no accessory structures unless specifically allowed).
• Property must be free of unresolved zoning/building violations.
• Fees: Under current rules, first-year permitting costs commonly reach a few thousand dollars due to BOA and permit fees; renewals are required every six months initially and then annually. The county has proposed lowering fees to reflect reduced staff demands under its draft regulations.

Current eligibility criteria to verify prior to application:

• Minimum one-acre lot size (subject to change if proposed updates are adopted).
• No more than five bedrooms.
• Compliance with underlying zone district standards.
• Adequate parking.
• Wildfire Hazard Overlay/defensible space requirements met.
• Valid water and sanitation.
• Legal access.
• Use of the primary dwelling unit.
• Property free of violations.

Specific Regulations (County and Proposed Updates)

Jefferson County treats STRs as residential uses. Building codes, taxation, and review all follow residential standards. STR approval is a two-step process (BOA Special Exception, then STR permit), and the approval does not run with the land.

Current operating standards include:

• Lot size minimum: one acre.
• Bedroom cap: no more than five.
• Use of the primary dwelling unit only.
• Compliance with underlying zoning.
• Adequate parking.
• Defensible space/wildfire hazard compliance.
• Valid water and sanitation.
• Legal access.
• Property free of violations.
• Permit validity: six months initially, then annual renewals.

Proposed regulatory changes under public review in 2025 include:

• Eliminate the public hearing requirement for new and renewal STR permits.
• Remove lot-size and zone-district limitations, replacing them with clear, objective criteria for administrative approvals.
• Lower the fee schedule.
• Expand STR eligibility to Accessory Dwelling Units, Duplexes, and Townhomes.
• Define two STR types—Primary Residence STR and Investment Property STR—with specific caps and separation requirements.
• Strengthen enforcement via a county ordinance and the use of Host Compliance for identification, monitoring, and a 24/7 complaint hotline.

Investors should confirm the status of these proposals and any adopted amendments before applying.

State-Level Notes (Colorado)

Colorado generally regulates STRs at the local level. In Jefferson County unincorporated areas (including Conifer), STRs must comply with the county’s rules described above. While there is no statewide STR permit, STR operators typically must collect and remit state sales and lodging taxes through the Colorado Department of Revenue. Always verify current tax obligations with the state and local authorities.
