COS Domain 8: Tenant Screening and Lease Requirements

What Domain 8 Actually Covers

The Certified Occupancy Specialist (COS) credential is built around eight distinct domains, and Domain 8 - formally titled Tenant Screening, Selection, and Lease Requirements - sits at the operational end of the certification. While earlier domains establish eligibility rules, income calculations, and recertification cycles, Domain 8 asks a more practical question: once you know someone may qualify, how do you lawfully decide whether to house them, and what obligations govern the lease you sign with them?

For property managers, compliance officers, and occupancy specialists working in HUD-assisted multifamily housing, this domain reflects decisions made every week. Screening an applicant incorrectly, using a lease that omits a required addendum, or terminating a tenancy without following proper notice procedures can all expose an owner or management agent to HUD sanctions, fair housing complaints, or legal liability. The COS exam tests whether candidates genuinely understand these stakes - not just whether they can recall definitions.

Tenant Screening Fundamentals Under HUD Programs

The Written Screening Policy Requirement

HUD-assisted properties are not free to screen applicants however they choose. One of the foundational concepts in Domain 8 is that owners must maintain a written tenant selection plan that documents the criteria used to evaluate applicants. This plan cannot be invented on the fly for individual applicants - it must exist before any applicant is evaluated against it, and it must be applied consistently.

Candidates are expected to know what a tenant selection plan must contain, including the types of criteria that are permissible (credit history, rental history, criminal background under specific HUD guidance) and those that require very careful handling to avoid disparate impact liability. The exam will probe whether you understand the difference between criteria that relate to an applicant's ability to meet lease obligations and criteria that function as unlawful screening tools.

Criminal History Screening Under Current HUD Guidance

Criminal history screening is one of the more nuanced areas in Domain 8. HUD guidance has moved away from blanket exclusions based on arrest records or broad criminal history and toward an individualized assessment approach. Candidates must understand why: an arrest record with no conviction is not evidence of criminal conduct, and blanket policies based solely on conviction history can produce disparate impact on protected classes under Fair Housing law.

The exam tests whether candidates know that an individualized assessment considers the nature and severity of the offense, the time elapsed, and evidence of rehabilitation. This is not merely a policy preference - it is a compliance expectation for HUD-assisted properties.

Adverse Action Notices and Denial Documentation

When an applicant is denied housing, the process does not end with the rejection. HUD-assisted owners must provide a written adverse action notice that explains the reason for denial, informs the applicant of their right to appeal or grieve the decision, and complies with any applicable Fair Credit Reporting Act requirements if the decision was based on a consumer report. Domain 8 candidates must be able to identify what a compliant adverse action notice includes and understand the timelines involved.

Selection Criteria, Fair Housing Intersections, and Section 504

Domain 8 does not exist in isolation. It is deeply connected to Domain 3: Fair Housing and Section 504, and candidates who treat these as separate subjects will find themselves struggling with scenario-based questions that cross both domains.

Every screening criterion carries a fair housing risk if applied in a way that produces disparate treatment or disparate impact on a protected class. The COS exam regularly presents factual scenarios - a property manager who applies a stricter income standard to applicants from one neighborhood, or a lease requirement that effectively excludes people who use mobility devices - and asks candidates to identify the violation and the correct course of action.

Candidates preparing for the COS exam should review how the fair housing protected classes interact with common screening criteria, including source of income protection in jurisdictions where it applies, familial status considerations in occupancy standards, and the specific obligations that attach under Section 504 for federally assisted properties. If you are still building your understanding of these intersections, the broader context of COS Exam Requirements: Eligibility and Prerequisites can help you understand how the credential is structured and what foundational knowledge is assumed before you sit for the exam.

Lease Requirements: What Specialists Must Know Cold

The HUD Model Lease and Required Addenda

One of the most specific and frequently tested areas in Domain 8 is the structure of the HUD-assisted lease. HUD does not simply allow any standard residential lease - it mandates specific provisions and, critically, requires that a Housing Assistance Payments (HAP) contract addendum be incorporated into every assisted tenancy. This addendum is part of the lease, not a separate document that sits in a file. Candidates must understand what it contains, why it exists, and what happens when it is absent.

The HUD model lease includes provisions about tenant and owner responsibilities, the conditions under which rent can be adjusted, the proper procedures for lease termination, and the tenant's right to a grievance process. These provisions are not optional, and they cannot be superseded by a locally drafted lease that omits them.

House Rules and Their Limits

Many COS candidates overlook house rules as a minor administrative topic. The exam treats them more seriously. House rules must be incorporated into the lease by reference, cannot conflict with lease terms or HUD regulations, and must be applied consistently across all tenants. A house rule that effectively imposes a greater burden on a protected class, or one that is selectively enforced, becomes a fair housing problem quickly.

The exam may present a scenario where a property manager enforces a house rule against one tenant but waives it for others, or where a house rule about guests creates a de facto barrier for tenants with disabilities who require live-in aides. Recognizing these patterns is a core Domain 8 competency.

Grievance Procedures and Lease Termination Rules

The Grievance Process as a Tenant Right

HUD-assisted tenants have a right to grieve adverse decisions made by management, including lease terminations, rent increases they believe are calculated incorrectly, and alleged violations of their rights under the lease. The grievance process is not optional - it must be offered, and the procedures must be written, disclosed to tenants, and followed consistently.

Domain 8 tests whether candidates understand the steps of the grievance process, including the informal conference requirement, the written decision requirement, and the conditions under which a tenant can escalate beyond the informal level. The exam also tests what happens when management fails to follow grievance procedures correctly - an area where compliance errors can result in regulatory findings.

Lease Termination: Notice, Cause, and Process

Terminating a HUD-assisted tenancy is substantially more constrained than terminating a conventional lease. Owners may only terminate for good cause, which includes nonpayment of rent, serious lease violations, criminal activity, and other specified grounds. Owners cannot terminate simply because a tenancy is inconvenient or because they prefer a different tenant.

Candidates must also understand the distinction between termination for nonpayment of rent and termination for other lease violations. The timing, notice requirements, and grievance rights may differ, and conflating them is a common source of exam errors. Practice distinguishing these scenarios before your test date - the COS practice test platform includes scenario-based questions specifically designed to test this distinction.

How Domain 8 Questions Are Structured on the COS Exam

The COS exam uses scenario-based, multiple-choice questions. Domain 8 questions rarely ask you to recall a single fact in isolation. Instead, they present a situation - a property manager who denied an applicant, a lease that is missing a required provision, a tenant who filed a grievance - and ask you to identify what the correct action is, what the violation is, or what step should come next in the process.

This format rewards candidates who understand why the rules exist, not just what the rules say. When you encounter a question about a denied applicant, for example, you need to think through: Was there a written screening policy? Was it applied consistently? Did the adverse action notice include all required elements? Was the denial based on a protected characteristic? Was a reasonable accommodation offered if applicable?

Reading the full COS Domain 8: Tenant Screening and Lease Requirements material thoroughly - including HUD Handbook 4350.3 REV-1 chapters on tenant selection and leasing - will give you the regulatory grounding the exam assumes you have. The COS Exam Prep practice tests mirror this question style and are one of the most efficient ways to test whether your understanding is deep enough to handle scenario variations.

How Domain 8 Connects to the Rest of the COS Framework

No COS domain is fully self-contained, but Domain 8 has particularly strong connections to several other areas of the exam:

• Domain 2 (HUD Multifamily Occupancy Requirements): The lease requirements in Domain 8 are grounded in the broader HUD program structure covered in Domain 2. Understanding which program governs a property determines which lease form and which lease provisions apply.
• Domain 3 (Fair Housing and Section 504): Every screening decision, selection criterion, and lease provision must be evaluated through the fair housing lens. Domain 8 cannot be mastered without fluency in Domain 3.
• Domain 4 (Eligibility, Income, and Assets): Screening connects to eligibility - candidates must understand the relationship between eligibility determinations and tenant selection criteria.
• Domain 7 (Annual and Interim Recertification): Lease renewal and recertification are connected processes. Understanding how a tenant's ongoing eligibility affects their lease status is a Domain 7/Domain 8 intersection the exam tests.

A Domain-by-Domain Preparation Schedule

Because Domain 8 overlaps with multiple other domains, how you schedule your preparation matters. Below is a practical framework for building toward Domain 8 mastery:

This sequence is deliberate: you cannot fully understand tenant screening under HUD programs without first understanding which programs apply (Domain 2) and what fair housing rules constrain every decision (Domain 3). Candidates who jump directly to Domain 8 without that foundation tend to miss the regulatory reasoning that scenario-based exam questions require.

If you are still confirming whether you meet the requirements to sit for the COS exam, review the details at COS Exam Requirements: Eligibility and Prerequisites before building your study schedule.
