Validate your shipping container home against IRC 2021 building codes • Get instant compliance report • Identify permit approval issues before submission

Container Home Permit Compliance Checker: Free IRC 2021 Validation Tool

Our container home permit compliance checker is a free tool that validates your shipping container home against IRC 2021 building codes. This tool helps you identify code violations before submitting permits, saving thousands in rejected applications and delays.

Building departments reject **over 60% of container home permits** due to easily avoidable code violations. Use this checker to identify compliance issues before spending thousands on plans and permit fees.

📋 IRC 2021 Reference: This compliance checker validates against IRC Section R301.1.4 (Intermodal Shipping Containers). Download IRC Code (opens in new window)

1 Container Specifications

⚠️ IRC §R305.1 requires 7’6″ (90″) minimum ceiling height in habitable spaces. Standard containers typically fail this requirement.

Total containers in your project (including stacked units)

Will containers be stacked vertically?

📌 Stacked containers require: IRC §R301.1.3 engineered connections, seismic calculations, and uplift resistance per IRC §R403.1.6

⚠️ Building inspectors may reject heavily damaged containers. One-Trip or Cargo Worthy condition recommended for permits.

2 Location & Climate Requirements

State determines specific building codes, wind/snow loads, seismic requirements, and permit fees

📌 Climate zone determines insulation requirements per IRC Chapter 11. Find your zone: ICC Climate Zone Map (opens in new window)

⚠️ Seismic Categories D0-D2 require enhanced structural connections. Check: USGS Maps (opens in new window)

3 Use & Occupancy Classification

⚠️ Commercial use requires IBC compliance instead of IRC. More complex: fire ratings, ADA accessibility.

Each bedroom requires emergency egress window per IRC §R310

Some jurisdictions have minimum square footage requirements (600-1000 sq ft)

Do you have professional engineering drawings?

🚨 CRITICAL: IRC §R301.1.3 requires PE-stamped structural drawings for ALL container modifications. No exceptions.

4 Foundation & Site Conditions

📌 Pier & Beam most common: Cost-effective ($3,000-$8,000 per container). IRC Chapter 4 governs foundations.

IRC §R403.1.4 requires footings extend below frost depth

Is the site in a FEMA flood zone?

⚠️ IRC §R322 requires elevated foundations in flood zones. Check: FEMA Maps (.gov) (opens in new window)

📌 Geotechnical report ($500-$1,500) recommended for all container homes.

5 Structural Modifications

Will you cut openings for doors/windows?

⚠️ Every opening requires PE-stamped reinforcement details.

Will you remove interior walls between containers?

⚠️ Removing walls requires engineered beams. Increases complexity.

6 Utilities & Systems

📌 IRC Chapter 11 requires specific R-values by climate zone. Steel needs continuous insulation.
