Fannie Mae recently released updates to its Multifamily Property Condition Assessment (PCA) requirements that will have an immediate impact on how PCAs are reported. The revisions include updates to Form 4099- Instructions for Performing a Multifamily Property Condition Assessment, and Form 4099.G - Known Problematic Materials and Property Design Issues. Among the most notable changes are new requirements related to the remediation of aluminum wiring.
These changes are effective immediately and apply to all PCA reports currently in progress. For properties with draft reports already under Fannie Mae review, borrowers and lenders should consult directly with their Fannie Mae representative for guidance on how the updates may affect prior submissions.
What This Means for Borrowers and Lenders
These updates reinforce Fannie Mae's continued focus on property condition and long-term risk management for multifamily assets. Borrowers and lenders should anticipate more detailed documentation requirements and, in some cases, additional immediate repair recommendations for properties with aluminum wiring.
Aluminum branch wiring is commonly found in older multifamily properties and is frequently identified during due diligence. Under Fannie Mae's updated requirements, permanent remediation can create unexpected repair obligations that affect underwriting, repair escrows, and transaction timelines. When aluminum wiring is discovered, early identification and planning are increasingly important for borrowers and lenders.
Overview of Aluminum Wiring Changes
The most significant revision affects how aluminum branch wiring is addressed in multifamily properties. Under the updated guidance, Fannie Mae now requires a permanent repair method at all properties where aluminum wiring is present. Previously accepted non-permanent retrofits, including CO/ALR devices and Ideal 65 purple wire nuts, are no longer considered acceptable.
Under the revised standard, acceptable permanent repair methods are limited to three options:
• Complete copper rewiring of the building
• Copper pig-tailing at receptacles using COPALUM crimp connectors
• Copper pig-tailing at receptacles using AlumiConn connectors
The updated guidance emphasizes that all aluminum-to-aluminum or aluminum-to-copper wiring connections must be addressed, such as appliances directly connected to No.12 or No.10 AWG aluminum branch circuit wiring (e.g. dishwashers, HVAC equipment, heaters, air conditioners, and hard-wired light fixtures), in addition to junction boxes, panel boxes, wall outlets and switches.
Implications for PCA Reports
From an assessment standpoint, the core inspection approach remains largely unchanged. Assessors are required to determine whether aluminum wiring is present by observing branch wiring at electrical panels and branch wiring connections. This verification must be completed within each phase of construction and must include inspection of switches, receptacles, hard-wired fixtures, and applicable appliances. If aluminum wiring is identified, the assessor must verify whether a retrofit has been installed and clearly document the condition of the observed system and whether it has any reported history of malfunction.
Repair Classifications and Recommendations
When aluminum wiring is present and a permanent repair has not been installed at all required locations, the PCA must now recommend installation of a permanent repair, including either COPALUM or AlumiConn connectors, or full copper rewiring, as an immediate repair.
Repair classifications should continue to be determined based on observed condition, reported performance, and estimated useful life. If the wiring shows no evidence of distress or malfunction, a Deferred Maintenance repair classification may still be appropriate. However, if there is a known history of electrical issues, overheating, or fire events, the repair classification may escalate to Critical or Life Safety, depending on severity.
Keep Your Deals On Track
Engaging PCA consultants who closely track agency guidance is critical to avoid review delays and ensure reports align with current underwriting expectations. As standards continue to evolve, early coordination during the due diligence process can help create clearer outcomes and smoother transactions for all parties involved.
