Tips for a Successful Final Building Inspection to earn your Certificate of Compliance.

Reviewing your states and your local municipal codes is important. You'll find Louisiana Plumbing codes within this review. You may find similar points for your state.

Attic Access [IRC 807]
Issue: Improperly sealed attic access allows air leakage.
Correction: Install a tight-fitting, insulated cover over the attic access.
Reason: The unsealed access creates an air gap, reducing overall energy efficiency.

Attic Insulated R-30 [IRC N1101]
Issue: Inadequate insulation below the R-30 standard.
Correction: Increase insulation to meet R-30.
Reason: Lower insulation reduces thermal resistance, causing energy loss.

Attic Venting [IRC 806]
Issue: Blocked or insufficient ventilation.
Correction: Ensure proper venting, like ridge vents or soffits.
Reason: Poor ventilation traps air, increasing moisture and energy use.

Site work &; grading complete [IRC 401.3]
Issue: Incomplete grading causes water pooling, leading to air and water intrusion.
Correction: Complete grading for proper water runoff.
Reason: Poor drainage leads to moisture issues and affects insulation performance.

Issue: Missing or improperly sealed access panel.
Correction: Install and seal access panels.
Reason: Gaps or openings from unsealed panels can contribute to air leakage, affecting the test result.

Septic/Sewer Complete and Operable [LSPC 701]
Issue: Incomplete or non-operational septic/sewer system.
Correction: Ensure the system is fully installed and operational.
Reason: Improper installation can create conditions that allow air and moisture intrusion.

Water Heater Shut-Off Valve [LSPC 509(A)]
Issue: Missing or inaccessible shut-off valve.
Correction: Install a shut-off valve in a readily accessible location.
Reason: Leaks or water control issues can contribute to humidity and air quality problems, which impact the blower door test.

Equipment Installation Complete/Operable [IRC 1307]
Issue: Incomplete or non-operable equipment.
Correction: Ensure all equipment is properly installed and functional.
Reason: Non-operable equipment can lead to system inefficiencies and air leakage.

Access to Equipment [IRC M1305.1]
Issue: Inadequate access to equipment.
Correction: Ensure sufficient access to all mechanical systems.
Reason: Poor access may prevent maintenance, which can lead to inefficiencies or air leakage.

Condensate Drainage [IRC M1411.3]
Issue: Blocked or improperly installed drainage system.
Correction: Fix or unclog the condensate drainage.
Reason: Improper drainage can cause moisture buildup, increasing humidity and impacting the blower door test.

Gas Appliance Shut-Off Valves [IRC G2420.5]
Issue: Missing shut-off valve for gas appliances.
Correction: Install shut-off valves at each gas appliance.
Reason: Inadequate control of gas appliances could lead to safety and air quality issues.

Gas Appliance Protection/Elevation [IRC G2406 &; 2408]
Issue: Gas appliances not properly protected or elevated.
Correction: Ensure protection or elevation is installed according to code.
Reason: Improperly installed gas appliances can affect airflow and overall building safety.

Dryer Duct Marking When Concealed &; >35 ft [IRC M1502.4.5]
Issue: Concealed dryer duct not properly marked.
Correction: Mark the dryer duct’s path when concealed.
Reason: Unmarked ducts can lead to maintenance issues and inefficient air handling, which affects the blower door test.

Equipment Protection [IRC M1307.3.1]
Issue: Equipment exposed to potential physical damage.
Correction: Install protective barriers as required.
