HUD Special Claims Processing Guide, Appendix 5D

HUD Special Claims Processing Guide (HSG-06-01, June 2006) - Appendix 5D, Sample Life Expectancy Chart

HUD's own chart of how long rental components are expected to last, published in the guide that tells owners how to charge a departing tenant for damage. It calls itself a sample and binds owners of HUD-assisted properties; elsewhere it is persuasive federal guidance, not law.

HUD Special Claims Processing Guide, Section 5-3(D)

HUD Special Claims Processing Guide (HSG-06-01) - Chapter 5, Special Claims for Unpaid Rent and Tenant Damages

The proration rule behind every number on this site: HUD's worked example caps the charge for carpet replaced after two years of a five-year life at 2/5 of replacement cost, and charges nothing once the life is spent.

Source:U.S. Department of Housing and Urban Development

Key Provisions

  • Useful life must be determined before charging a tenant for a replaceable item
  • Worked example: carpet two years into a five-year life - tenant share 2/5

IRS Publication 527

IRS Publication 527 - Residential Rental Property

Tax depreciation only. It sets no standard for damage or deposit deductions, and we never cite it as one - it appears here because it confirms that appliances and carpet are short-lived, depreciating assets.

Source:Internal Revenue Service

Key Provisions

  • Appliances, carpets and furniture in a residential rental: 5-year GDS property (Table 2-1)
  • The building and its structural components, including furnaces: 27.5 years
  • Depreciation is a tax convention, not a measure of what a tenant owes

Analysis Methods

How We Analyze Each Case

Each Shield Apps tool follows a structured methodology tailored to its specific legal domain.

Security Deposit Analysis

Federal Guidelines, State-Specific Application

Our security deposit analysis methodology applies federal depreciation standards from HUD and IRS guidelines to evaluate landlord deduction claims. Each charge is assessed against established useful life schedules to determine whether deductions exceed what federal guidelines permit.

State-specific statutes (return deadlines, itemization requirements, penalties) are cited from official state codes.

Analysis Process

1
Extract Claimed Charges

Parse landlord itemization to identify each deduction with amounts and categories.

2
Apply Federal Depreciation Standards

Calculate remaining value against HUD's sample life expectancy chart (Special Claims Guide, App. 5D).

3
Assess Evidence Against Standards

Evaluate photographic evidence against normal wear definitions from HUD guidelines.

4
Generate Statutory Citations

Compile relevant federal guidelines and state-specific statutes for each contested charge.

HOA Violation Analysis

Procedural Compliance Review

Our HOA violation analysis focuses on procedural compliance—whether the HOA followed required notice, hearing, and enforcement procedures under state law. Many violations can be contested based on procedural defects alone.

All citations reference official state HOA statutes (e.g., California Civil Code §4000 et seq., Florida Statute Chapter 720).

Analysis Process

1
Identify State Governing Law

Determine applicable HOA statute (Davis-Stirling, Chapter 720, etc.) based on property location.

2
Review Notice Requirements

Verify HOA provided required advance notice (typically 10-30 days) before imposing fines.

3
Assess Hearing Rights

Confirm whether homeowner was offered required hearing opportunity before fine assessment.

4
Check Fine Limitations

Compare fines against state-mandated caps and escalation limits.

F&I Product Cancellation Analysis

State Consumer Protection Laws

Our dealer add-on analysis applies state-specific cancellation rights and refund requirements for F&I products. Most extended warranties, GAP insurance, and add-on products are cancellable by law with pro-rata refunds.

State citations include specific consumer protection codes (e.g., California Civil Code 1794.41, Wisconsin Admin. Code ATCP 139).

Analysis Process

1
Identify Product Type

Classify F&I product (extended warranty, GAP, service contract) to determine applicable regulations.

2
Apply State Cancellation Rights

Reference state-specific free-look periods, cancellation procedures, and refund deadlines.

3
Calculate Pro-Rata Refund

Determine refund amount based on unused time/mileage per state requirements.

4
Generate Cancellation Letter

Produce compliant cancellation request citing applicable state laws.

Lease-End Charge Analysis

Industry Standards & Federal Regulation

Our lease-end analysis applies industry-standard wear guidelines (such as the "credit card test") and Federal Regulation M requirements to evaluate excess wear charges at lease termination.

Manufacturer wear guides (BMW, Mercedes, Toyota, etc.) are referenced for brand-specific thresholds.

Analysis Process

1
Review Inspection Report

Analyze lessor inspection findings against manufacturer wear guidelines.

2
Apply Industry Standards

Compare damage claims against accepted thresholds (credit card test, 6-foot visibility rule).

3
Verify Regulation M Compliance

Ensure charges comply with federal disclosure and limitation requirements.

4
Generate Dispute Letter

Produce dispute citing specific wear guide thresholds and federal regulations.

GAP Insurance Refund Analysis

Pro-Rata Refund Requirements

Our GAP refund analysis applies state insurance regulations requiring pro-rata refunds when GAP coverage is cancelled before the coverage period ends.

State insurance commissioner regulations govern GAP refund requirements by state.

Analysis Process

1
Verify GAP Product Type

Determine if GAP is insurance-regulated or dealer waiver product.

2
Calculate Unused Coverage

Determine remaining coverage period or mileage for refund calculation.

3
Apply State Refund Requirements

Reference state-specific refund timelines and calculation methods.

4
Generate Refund Request

Produce compliant refund request citing applicable state insurance regulations.

IRS Penalty Abatement Analysis

First Time Abate & Reasonable Cause

Our IRS penalty analysis maps each assessed penalty to the relief paths defined in the Internal Revenue Manual. We check the objective First Time Abate criteria (IRM 20.1.1.3.3.2.1) and, where FTA does not apply, the reasonable-cause standard, then cite the exact Internal Revenue Code section and IRM provision for the penalty at issue.

IRS penalty relief is governed by federal law (Internal Revenue Code and Internal Revenue Manual); penalty determinations and abatement are made solely by the IRS.

Analysis Process

1
Identify the Penalty and Notice

Read the IRS notice to determine the penalty type (failure to file, pay, deposit, accuracy, etc.) and tax period.

2
Check First Time Abate Eligibility

Apply the three IRM 20.1.1.3.3.2.1 requirements: clean 3-year history, filing compliance, and payment compliance.

3
Evaluate Reasonable Cause

Where FTA does not apply, assess whether circumstances beyond the taxpayer's control support reasonable-cause relief.

4
Generate the Abatement Request

Produce a request citing the exact IRC section and IRM provision for the penalty and the relief path that fits the facts.
