Park County Septic Requirements
Park County Septic Requirements — OWTS Compliance for Property Sales & Short-Term Rentals
We’ve seen Park County deals slip because inspections were booked too late, lids were still buried, or nobody realized the system wasn’t in county records until the last minute.
South Platte Services has been running inspection, pumping, and county paperwork on septic systems throughout Park County for more than 50 years. We work regularly with sellers, buyers, real estate agents, and STR owners in Bailey, Fairplay, Alma, and across South Park on Transfer of Title inspections, pumping, and county documentation.

Park County Has Two Separate Septic Compliance Tracks
This is the most important thing to understand before scheduling anything.
Track One — Transfer of Title (Property Sales) If you are selling a property in Park County served by a septic system, Park County requires a Transfer of Title OWTS inspection and permit prior to closing. This is a one-time compliance review triggered by the transfer of ownership.
Track Two — STR Licensing (Short-Term Rentals) If you are operating or applying for a short-term rental license in Park County on a property served by a septic system, Park County requires OWTS documentation as part of the STR licensing process. The 2026 Park County STR ordinance formally ties STR licensing to verified septic documentation — and for properties with undocumented or unpermitted systems, the STR license will not be issued until the system is fully permitted, inspected, and closed with the county.
These are separate requirements. A property may be compliant for a sale but still need updated documentation for STR licensing. If you’re unsure which track applies to your situation, call us or confirm directly with Park County Environmental Health before scheduling.
A Note on Terminology
Park County uses its own terminology and forms — different from Jefferson County. Park County calls this process a Transfer of Title OWTS inspection and permit, not a Use Permit. If you’ve dealt with Jefferson County requirements before, don’t assume the process, forms, or timelines are the same. They’re not interchangeable.

Track One — Transfer of Title Requirements
When is a Transfer of Title inspection required?
A Transfer of Title OWTS inspection and permit is required whenever a Park County property served by a septic system transfers ownership, unless the system qualifies for one of the narrow exemptions in Park County’s OWTS regulations. If you’re selling a property in Bailey, Fairplay, Alma, or anywhere else in Park County on septic, assume the inspection is required and confirm any exemption directly with Park County Environmental Health before listing.
What the process involves
The Transfer of Title process in Park County requires:
- A completed OWTS Transfer of Title Permit Application submitted to Park County Environmental Health
- A Transfer of Title inspection performed by a NAWT-certified inspector using Park County’s approved inspection form
- Submission of the completed inspection report and application with the applicable permit fee
- Park County Environmental Health review and issuance of the Transfer of Title permit
The inspection documents system type and components, tank condition, soil treatment area condition, distances to wells, evidence of failure, and O&M status for advanced systems.
Processing time
Park County typically processes Transfer of Title permits within 7 to 10 business days after a complete inspection report and application are submitted. During peak season — May through September, when transaction volume is highest — processing can take longer.
Plan for at least one to two weeks between inspection submission and closing. Do not treat Transfer of Title approval as a same-week turnaround, and do not schedule the inspection in the final days of the contract period.
What actually happens on older Park County properties
Park County is largely rural and mountain-rural. Most residential properties in Bailey, along the US-285 corridor, throughout South Park, and in the surrounding foothill communities are on individual OWTS systems — many of them older, and some with incomplete or missing county records.
On older properties, a few things consistently cause Transfer of Title delays:
- Inspection scheduled too late in the contract period — no room for county processing time or findings
- System components that have changed since original installation with no updated county documentation
- Buried or inaccessible lids — that usually means a separate locate trip before we can even inspect, and it pushes the whole timeline out
- Advanced systems with missing or lapsed O&M agreements
- County records that don’t reflect the actual system as-built — more common in Park County than most sellers expect
In Park County and the surrounding mountain communities, most of the advanced residential systems we work on are built around a few platforms we see repeatedly — Orenco AdvanTex filters, Norweco aerobic systems like the Singulair line, and MicroFAST BioMicrobics units — usually tied into pressure-dose or mound systems on properties with slope, shallow bedrock, seasonal groundwater, or difficult native soils. If the O&M paperwork on the advanced-system side is stale, it can slow down both Transfer of Title timelines and ongoing county compliance.
Most of these are manageable when there’s enough time. Almost all of them become harder once the contract period is already running. Run through that list before you put the property on the market.
If you’re already under contract and haven’t scheduled yet, call us today. We’ll tell you honestly whether the timeline is workable — and if there’s a real problem, better to know now than at the closing table.
Track Two — Park County STR Septic Requirements (2026)
Park County’s Short-Term Rental ordinance, adopted April 7, 2026, formally ties STR licensing to verified OWTS documentation for properties served by septic systems.
What Park County currently requires for STR applications on septic
STR applicants in Park County on septic must provide:
· Original septic documents with system design information, or a recent Transfer of Title inspection and permit
The undocumented system issue — the most important thing STR owners need to know
If the OWTS serving an STR property is not documented in Park County records, the STR license will not be processed or issued until an undocumented system permit is obtained, the system is inspected and approved, and the permit is closed with the county.
This is a significant compliance gap for older Park County properties — particularly rural parcels, older cabins, and properties that changed hands multiple times before county record-keeping was consistent. It’s not uncommon in Park County for a property’s septic system to have no county documentation at all, especially on older parcels throughout South Park and the Bailey area.
If you’re operating or planning to operate an STR on a Park County property and you’re not certain your septic system is documented in county records, find out before you apply for a license — not after it’s denied. Park County Environmental Health can tell you whether your system is on record — call them directly, or call us and we’ll help you figure it out before you apply.
We work through undocumented system permitting in Park County regularly. Call us before you apply — the permitting process takes time, and starting it mid-application is the harder way to do it.
How Park County STR requirements differ from Jefferson County
Jefferson County’s STR rules require an OWTS Use Permit with inspection within 90 days of the application, creating an effective annual inspection cycle tied to license renewal.
Unlike Jefferson County, Park County’s STR rules are less about annual inspection timing and more about whether the system is properly documented and permitted with the county in the first place. What the ordinance requires is that undocumented systems be fully brought into compliance before a license is issued.
In Park County, the bigger STR issue usually isn’t annual inspection timing — it’s whether your system is documented in county records at all.
Our Specialist Crew Model
South Platte runs dedicated inspection technicians and dedicated pump truck crews — meaning inspection and pumping are handled by specialists in each, not the same person doing both.
Inspection must happen before pumping for several reasons, including confirming the effluent is at proper operating level. With dedicated crews, we can often schedule both on the same day when timing allows — inspection first, pumping after.
Whether you’re lining up a Transfer of Title inspection, STR paperwork, or routine septic work, we’ll match the job to the exact Park County forms it needs so you’re not guessing on documentation.
If you’re under contract or up against an STR application deadline in Park County, say that up front when you call. We’ll line up inspection and pumping in the order that makes sense for the county’s Transfer of Title and STR rules, and we build the schedule around the hardest deadlines first.

Frequently Asked Questions
Does Park County required septic inspection before selling a property?
Yes. A transfer of Title OWTS inspection and permit is required for most Park County property sales served by septic. If you think your system may qualify for an exemption, confirm that directly with Park County Environmental Health before listing — don’t assume.
How long does Park County take to process a Transfer of Title application?
Typically 7 to 10 business days after a complete inspection report and application are submitted. Processing takes longer during peak season — May through September. Plan for at least one to two weeks and build that into the contract timeline.
Is the Park County process the same as Jefferson County's Use Permit?
No. Park County uses its own Transfer of Title OWTS inspection and permit process with Park County-specific forms. Don’t assume Jefferson County procedures, timelines, or terminology apply in Park County. They don’t.
What if the lids are buried or inaccessible?
Let us know before we schedule. If lids can’t be accessed on inspection day, that usually means a separate locate trip before we can even inspect — and it affects the timeline. Knowing upfront is much better than finding out on inspection day.
Is pumping required as part of the Transfer of Title Inspection?
In practice, tanks that haven’t been pumped in recent months are often pumped as part of the process. If you have recent pumping documentation, let us know when you call so we can factor that into scheduling.
Does Park County require septic documentation for STR licensing?
Yes. Park County’s 2026 STR ordinance requires original septic documents or a recent Transfer of Title inspection as part of the STR application. If the system is not documented in county records, the STR license will not be issued until the system is fully permitted and inspected.
What if my septic system isn't in Park County's records?
This comes up regularly on older Park County properties. An undocumented system must be permitted, inspected, approved, and closed with the county before an STR license will be issued. Call us before you apply — starting that process mid-application is the harder way to do it. The earlier you find out, the more time there is to get the system permitted before it stalls a sale or an STR license.
Can inspection and pumping happen the same day?
Often yes – inspection must come first. With dedicated inspection and pump crews, we can frequently schedule both on the same day when the window allows. If you’re working against a closing deadline or STR application timeline, tell us and we’ll prioritize accordingly.
Does Park County have the same annual STR inspection requirements as Jefferson County?
Not in the same explicit way. Jefferson County’s STR rules require inspection within 90 days of each annual license application. Park County’s 2026 ordinance focuses on documentation and permitting status rather than specifying the same annual inspection interval. Confirm current requirements with Park County Environmental Health for your specific situation.
What if the property has an advanced treatment system?
Advanced systems – including Orenco AdvanTex filters, Norweco Singulair aerobic units, and MicroFAST BioMicrobics systems — have additional O&M requirements under Park County’s OWTS regulations. Those apply whether the property is being sold or operated as an STR. We handle O&M agreements and service documentation for advanced systems throughout Park County.
