The law went into effect January 1, 2026. If you are a Colorado landlord and you have not updated how you handle tenant screening, there is a real chance you are already out of compliance.
House Bill 25-1236 -- the latest update to Colorado's portable tenant screening report (PTSR) rules -- did not get a lot of press outside real estate circles. But it made significant changes to what you are required to accept from applicants, what you can charge, and what happens when you get it wrong.
This is not a scare post. It is a field guide. Here is what actually changed, what it means for your leasing process, and where the landmines are for self-managing landlords who have not caught up yet.
What Is a Portable Tenant Screening Report?
A PTSR is a background and credit report that a prospective tenant orders at their own expense from a consumer reporting agency (CRA) like TransUnion or Experian. The tenant pays once and reuses the same report across multiple properties, rather than paying a $40-$75 application fee at every unit they apply to.
Colorado first mandated PTSR acceptance in 2023 with HB23-1099. HB25-1236 is the update that tightened the rules, closed a loophole, and added new protections for subsidized tenants.
The concept is sensible. The implementation is where most landlords are getting tripped up.
What HB25-1236 Actually Changed
Three things shifted significantly as of January 2026.
1. Tenants can now deliver the PTSR directly to you.
Under the 2023 law, PTSRs had to be delivered through a CRA or third-party platform. That friction is gone. A prospective tenant can now hand you a PTSR directly -- via email, PDF, or any other method -- and you are required to accept it.
2. The credit rules for subsidized applicants changed.
If a prospective tenant is applying with a housing subsidy -- a Section 8 voucher, a state housing assistance program, any government-backed rental assistance -- their PTSR does not need to include credit history, credit scores, or adverse credit events. And you cannot use credit information to evaluate them regardless.
This is not new in spirit. Colorado has prohibited using credit against subsidized applicants in other contexts. HB25-1236 locked it into the PTSR framework explicitly.
3. The portal delivery requirement was repealed.
The old law let landlords require tenants to deliver their report through a specific third-party website. That language is gone. You cannot require a specific delivery method. Whatever format the tenant uses, you accept it.
What a Valid PTSR Must Include
Not every report a tenant hands you qualifies. For a PTSR to be legally valid, it must meet specific standards:
- Prepared by a consumer reporting agency at the tenant's request and expense
- Contains required information: employment and income verification, rental history, credit history, and criminal background (subsidized applicants are exempt from credit requirements)
- Current -- no older than 30 days at time of application (verify the exact window at leg.colorado.gov; one source cites a 60-day extension under HB25-1236, which would favor tenants -- treat 30 days as the safe floor)
- FCRA-compliant -- the CRA that produced it must operate under federal Fair Credit Reporting Act standards
If a report is missing required information, comes from a non-FCRA source, or is outside the validity window, you can decline it and request a compliant version. You can also charge a standard screening fee if no valid PTSR is provided.
The tradeoff the law establishes: a valid PTSR means a fee-free process. No PTSR means you can charge your normal fee.
When You Can Reject a PTSR
You are not required to accept everything someone prints out and hands to you. Legitimate grounds for rejection:
- The report is outside the validity window
- The report is missing required information (excluding lawful subsidy carveouts)
- The report was not prepared by a FCRA-compliant CRA
- The applicant does not qualify under your lawful, consistently-applied screening criteria
That last point matters more than most landlords realize. Accepting a PTSR does not mean accepting the applicant. Your screening standards still stand -- income ratios, rental history, criminal history, whatever your documented criteria are. You review the PTSR, evaluate the application against your criteria, and make your decision. The law controls how the report is delivered and whether you can charge a fee. It does not control your legitimate leasing criteria.
The Section 8 Wrinkle -- and Why It Matters in Denver
The subsidy credit prohibition is not theoretical here. Denver has active housing authority programs and voucher-based tenants in every submarket from Montbello to Wheat Ridge. If you have been running the same screening process for several years without updating it for voucher applicants, you may already be in violation.
The specific rule: if an applicant is using any form of housing subsidy, their PTSR does not need to include credit information. You also cannot use credit as a basis for denial for those applicants. Colorado has separate anti-discrimination provisions for source-of-income, and HB25-1236 reinforces that in the screening context.
What this means practically: you need different screening workflows for subsidized and non-subsidized applicants. Most self-managing landlords are running one process for everyone. That is a compliance gap.
Fraud Risk: How to Verify a PTSR You Did Not Order
Here is the part nobody talks about. We have seen tampered PTSRs. Income figures that do not match the CRA's formatting. Credit scores that look too round. Inconsistent font sizes on documents that should be system-generated. It is uncommon, but it happens, and a self-managing landlord with no comparison baseline will not catch it.
A few things that help:
Check the source. Every legitimate PTSR will have the issuing CRA's name, contact information, and report ID on it. Call the CRA and confirm the report ID exists.
Cross-reference the format. TransUnion, Experian, and the other major CRAs have consistent report formats. If something looks off -- different layout, unusual fonts, manually typed fields -- treat it as a red flag.
Verify income independently. A PTSR is not a substitute for asking for two months of pay stubs and your standard income verification. You can still request supporting documents. The law limits your ability to charge for screening. It does not prevent you from doing your job.
Trust your gut. If the report has an income figure that does not line up with their stated employment, ask. If they cannot explain the discrepancy, that is a legitimate reason to keep evaluating.
What This Means for Your Screening Process
In practice, your intake workflow needs a new decision point: when an applicant submits, ask whether they have a PTSR or would like to request one. If they provide a valid PTSR, do not charge a screening fee. If they do not provide one, use your standard process and charge your standard fee.
Document your decision either way. If you decline a PTSR as invalid -- wrong timeframe, missing information, questionable source -- document why. If you decline an applicant after reviewing a valid PTSR, document which criteria they did not meet. This paper trail is your protection if anyone files a complaint.
In Denver's rental market, qualified applicants know this law. The ones who show up with a PTSR ready are often among the most prepared tenants in the pool. A fast, compliant process attracts better applicants. Dragging your feet or quietly ignoring the law does the opposite.
The $2,500 Penalty Is Real
This is where most landlords need to pay attention. Colorado set a $2,500 per-incident penalty for violations of the PTSR rules. Not per lease. Not per property. Per incident.
If you charge an application fee after accepting a PTSR, that is $2,500. If you require a tenant to submit through a portal after the portal-delivery requirement was repealed, and they can document it, that is $2,500. If you reject a PTSR on grounds that do not qualify as legitimate rejection grounds, that is a potential $2,500 plus any fair housing exposure that attaches if the applicant is in a protected class.
For a landlord with two or three units who has been running an informal screening process, a single complaint can cost more than a year of rent. That is not a hypothetical -- it is the gap between knowing the law and not knowing it.
Colorado has been legislating landlords harder and faster than almost any other state in the country. HB25-1236 is not the last update. Staying current is a full-time job. For most self-managing landlords, it has quietly become a liability.
If Colorado's regulatory pace has you wondering whether self-management still makes sense, we are worth a conversation. At Sheepdog, PTSR compliance is baked into our intake process -- not something we scramble to update every legislative session. Talk to us here.
What a Property Manager Handles for You
Most of what HB25-1236 requires is process and documentation work -- the kind of thing that is straightforward if you have systems, and genuinely risky if you do not.
A competent Denver property manager handles all of it: intake triage, PTSR acceptance and validation, fraud checks against a known report format baseline, subsidy applicant workflows, documentation of decisions, and keeping the fee structure current with what the law permits.
At Sheepdog, we track regulatory changes as part of the job. When HB25-1236 went into effect in January, our intake forms were already updated. The landlords who hire us do not have to think about this stuff. They get the call when a qualified tenant is ready to sign.
The landlords who tend to panic about this law are the ones who were charging $50 application fees and using a free online form as their screening process. Good operators were doing most of this already.
Frequently Asked Questions
Do I have to accept a PTSR from every applicant in Colorado?
Yes, if it is a valid report -- prepared by a FCRA-compliant CRA, current, and containing the required information. You cannot require applicants to use a specific delivery method or platform, and you cannot charge a screening fee when a valid PTSR is provided. You can still apply your lawful screening criteria.
Can I still charge an application fee in Colorado?
If an applicant provides a valid PTSR, no. If they do not provide one, yes -- you can charge your standard screening fee. You cannot charge a fee and require a PTSR simultaneously.
What happens if I accidentally charged a fee after receiving a PTSR?
The Colorado statute sets a $2,500 per-incident penalty. Document the error, refund the fee immediately, and correct your process. If a complaint has already been filed, consult a Colorado landlord attorney.
Do Section 8 / voucher tenants still need to provide a PTSR?
They can provide one, but the credit components are not required and you cannot use credit history to evaluate subsidized applicants. Focus your screening on income verification (including subsidy amounts), rental history, and criminal background.
How do I know if a PTSR is real?
Check the issuing CRA's name and contact information, then verify the report ID directly with the CRA. Cross-reference the formatting against the CRA's known report style. Red flags include inconsistent fonts, manually typed fields, and income figures that do not match stated employment.
Do I need to update my lease or rental application for HB25-1236?
Your rental application should reflect the PTSR option and the fee structure that applies in each scenario. Your lease does not need to reference PTSR mechanics, but your intake process and screening criteria should be documented in writing in case of a complaint.
