Thinking about hosting an Airbnb or VRBO near Larkspur? The rules here are local, layered, and can change property by property. If you are buying a second home or evaluating an investment, you want clarity before you model returns.
In the Larkspur area, county-level requirements, safety standards, septic capacity, and even neighborhood-level documents can control what you can do. This guide explains how short-term rentals work around Larkspur in unincorporated Douglas County, what to verify, and the steps to take so you move forward with confidence. Let’s dive in.
How STRs are regulated locally
Around Larkspur, short-term rental activity is regulated by Douglas County rather than by the town itself. County rules can require a specific short-term rental license or registration and may set operating conditions you need to follow.
Typical county STR programs include:
- Registration or licensing with renewal timelines and fees.
- Lodging or transient occupancy tax collection and remittance.
- Life-safety inspections or certifications prior to licensing.
- Occupancy limits tied to bedrooms, egress, and parking.
- Rules for signage, parking, and complaint response.
Local Planned Development districts and recorded covenants may add stricter limits. Always confirm what applies to your specific parcel before you book your first guest.
Life-safety requirements
Life-safety standards protect guests and neighbors. Counties often verify these items before issuing an STR license, and noncompliance can lead to fines or license denial.
What to expect:
- Smoke and carbon-monoxide detectors where required by code.
- Adequate means of egress and, in some cases, exit lighting.
- Accessible fire extinguishers and posted emergency instructions.
- Clear occupancy limits based on sleeping rooms and safe egress.
- Visible address numbers and exterior access for first responders.
Ask the county Building or Fire Marshal which inspections are required, whether a third-party inspection is acceptable, and how long approvals typically take.
Septic (OWTS) compliance
Many properties around Larkspur use an on-site wastewater system. Short-term rentals can stress a septic system if occupancy jumps on weekends or holidays. Counties connect STR licensing to proof that your system can handle the flow.
Be ready to provide:
- Evidence of a permitted OWTS, such as original permits or installation records.
- Recent maintenance documentation, including pumping and inspection.
- Verification that system capacity matches proposed occupancy.
- Confirmation that setbacks and drainfield conditions meet standards.
If records are missing or the system is older, plan for a current inspection and a capacity estimate from a qualified professional. Adjust occupancy plans if the permit limits bedroom count or daily flow.
Zoning and PD limits
Zoning controls the use of land. In unincorporated Douglas County, standard zones may allow, restrict, or be silent on STRs. Even when zoning is silent, county licensing rules can still apply.
Planned Development districts are different. A PD has custom rules for a specific development. The PD plan, ordinance, or recorded covenants can explicitly prohibit short-term rentals or any lodging under a set duration, such as less than 30 days. A home can be fully legal for residential use and still be restricted from transient lodging within a PD.
If a parcel sits inside a PD, read the PD documents closely. Look for language about rental duration, transient lodging, or commercial use.
HOAs, easements, and special districts
Private rules can be as limiting as public rules.
- Homeowners’ association covenants often set minimum lease terms or prohibit STRs.
- Conservation easements, deed restrictions, and special districts can add conditions.
- Local fire district requirements and wildfire mitigation standards may affect occupancy and guest safety obligations.
HOA rules are enforceable even if the county issues a license. You need both the county’s approval and compliance with private covenants.
Due diligence steps before you model returns
Use this step-by-step checklist before you budget for nightly rates, occupancy, or renovations.
- Confirm jurisdiction
- Verify that the property lies in unincorporated Douglas County rather than inside an incorporated municipality with its own rules.
- Check zoning and PD status
- Pull the county GIS or parcel records to confirm zoning and whether a PD applies.
- If in a PD, obtain the PD ordinance or development plan and any recorded agreements or conditions.
- Read for explicit clauses about transient lodging or minimum rental terms.
- Request a written zoning verification or determination letter from county planning for confirmation.
- Confirm STR licensing and tax requirements
- Contact the county office that administers STR licensing.
- Ask whether a license is required for your use type and address.
- Request the application checklist, fees, renewal steps, and complaint process.
- Clarify lodging or transient occupancy tax obligations and how collection works.
- Verify life-safety requirements
- Confirm inspection requirements with the Building or Fire Marshal.
- Get a list of required devices and documentation.
- Ask about timelines for inspection and the typical time to license approval.
- Review septic (OWTS) records and capacity
- Request the OWTS permit and maintenance history from environmental health or the building department.
- If records are incomplete, schedule a current inspection and capacity review.
- Ensure planned occupancy does not exceed the permitted bedroom count or flow.
- Review HOA and deed restrictions
- Obtain CC&Rs and any HOA rules about rental duration and registration.
- Confirm enforcement practices and potential fines for violations.
- Understand enforcement and insurance
- Ask the county what triggers enforcement and the penalty structure for noncompliance.
- Confirm whether the county requires or recommends dedicated STR insurance and what minimums apply.
- Model all costs and contingencies
- License and renewal fees, life-safety upgrades, septic inspections or upgrades, taxes, increased insurance, and potential fines.
- Build a timeline that accounts for inspections and approvals before launch.
- Talk to local operators
- Speak with nearby property managers or operators for realistic occupancy, operating costs, guest expectations, and seasonal access issues.
Costs, timelines, and risks
Licensing programs involve fees and an application process. You may need to complete and pass inspections before hosts can accept bookings. Build time for sourcing PD documents and HOA approvals. If your septic inspection suggests upgrades, schedule that work early and adjust occupancy in your listings until improvements are complete.
Budget for these items:
- County license and renewal fees.
- Life-safety devices and any required signage or postings.
- Septic inspection, pumping, repairs, or capacity upgrades.
- Lodging or transient tax collection and remittance.
- STR-specific insurance coverage.
Operating without required approvals can result in fines, forced cessation of rentals, and revocation of future permits. If you inherit an active listing from a prior owner, do not assume approvals transfer. Start fresh with your own verifications.
If you already own or operate
If you have a property near Larkspur and want to legitimize or optimize your STR, take these steps:
- Pull your parcel’s zoning and PD status, then request written zoning verification.
- Order an OWTS records search and schedule a current septic inspection if needed.
- Walk through a life-safety checklist and correct any gaps before inspection.
- Contact the licensing office for the latest application checklist and taxes.
- Review your HOA rules and register with the HOA if required.
- Align occupancy limits with both egress capacity and septic permit constraints.
