What Completion Certification Means for Your HomeStyle Renovation
When you finish your HomeStyle renovation project, your lender cannot simply take your word that the work is done. Fannie Mae requires formal certification that everything was completed according to the original plans and specifications you submitted when you applied for the loan.
This certification process protects both you and the lender. It ensures the improvements you paid for were actually made and that they add the expected value to your home. Without proper completion certification, your lender cannot release the final renovation funds held in escrow.
The Form 1004D Requirement
Your lender must obtain an Appraisal Update and/or Completion Report using Form 1004D. This is the same appraiser who did your original renovation appraisal, and they need to physically inspect the completed work.
The appraiser will compare the finished renovation against the original appraisal that listed various "subject to" conditions. Say your original appraisal stated the value was "subject to completion of kitchen renovation including new cabinets, countertops, and flooring." The Form 1004D must confirm each of these items was actually installed.
If you made changes to the original plans during construction, the appraiser must note these deviations and determine if they impact the property value. Minor changes like switching from granite to quartz countertops typically won't affect value. But major changes like eliminating a planned bathroom addition could reduce the expected value significantly.
When Plan Changes Affect Property Value
If the appraiser determines that deviations from your original plans have reduced the property value, your lender must follow specific policies for unplanned changes. This could mean additional documentation, revised loan terms, or in extreme cases, requiring you to complete the original scope of work.
The appraiser might find that your contractor substituted lower-grade materials or eliminated planned improvements. In this scenario, the final appraised value could come in below the amount your loan was based on, creating complications for the final disbursement.
Certificate of Occupancy Requirements
Many renovation projects require a certificate of occupancy from local building authorities. This applies to major renovations like room additions, structural changes, or electrical and plumbing work that required permits.
Your lender must obtain this certificate before releasing final funds. If your local jurisdiction requires a certificate of occupancy for your type of renovation work, you cannot complete the loan process without it. This requirement varies by location and project scope, so check with your local building department early in the process.
Some minor renovations like cosmetic updates or landscaping typically don't require certificates of occupancy. But any work involving structural changes, new electrical circuits, or plumbing modifications usually does.
Title and Lien Protection Requirements
Before your lender releases the final renovation funds, they must update the title search through the completion date. This protects against any new liens that might have been filed during construction.
Construction projects create particular lien risks because contractors, subcontractors, and material suppliers can file mechanic's liens if they aren't paid. Your general contractor might pay their bills on time, but a subcontractor could still file a lien if there's a payment dispute.
The lender must obtain lien releases from all parties who worked on your project or supplied materials. In states where contractor liens can take priority over your mortgage, the lender must take additional steps to ensure clear title. This might include requiring lien waivers before each progress payment during construction.
Insurance Coverage Updates
Your property insurance needs to reflect the renovated property's increased value. The lender must obtain certification that your coverage has been increased appropriately to meet Fannie Mae's standard property and flood insurance requirements.
Say you started with a $300,000 home and added $75,000 in renovations. Your insurance coverage needs to increase to protect the new $375,000 value. If you're in a flood zone, your flood insurance may also need adjustment.
This insurance update must happen concurrent with the final fund disbursement. Your lender cannot release the last renovation payment until they have written confirmation that adequate insurance is in place.
Common Issues That Delay Completion Certification
Several problems can hold up your completion certification and final fund release. Contractors sometimes leave small items unfinished, thinking they can return later to complete them. But the appraiser must confirm 100% completion before signing off.
Permit issues frequently cause delays. If your contractor pulled permits but never got final inspections, you cannot get a certificate of occupancy. This stops the entire completion process until all inspections are passed and permits are closed.
Title problems can also emerge during construction. A subcontractor might file a lien even if your general contractor was paid in full. These liens must be resolved before the lender can complete the loan.
Weather damage during construction creates another complication. If a storm damages completed work, the appraiser might find that items previously marked as finished now need repair or replacement.
Documentation Your Lender Must Retain
Your lender must keep specific documentation in your loan file to prove completion certification was properly handled. This includes the completed Form 1004D, any certificates of occupancy, title updates, lien releases, and insurance certifications.
If you're in a UAD 3.6 area, your lender must follow additional requirements outlined in Fannie Mae's UAD 3.6 Policy Supplement. These requirements ensure consistent data reporting for completed renovation projects.
The documentation requirements protect you if questions arise later about whether the renovation was properly completed and certified. Complete records also help if you sell the home and the new buyer's lender wants to verify the renovation work.

Completion Certification
Following completion of the renovation work, the lender must obtain a certification of completion stating the renovation was completed in accordance with the submitted plans and specifications. The certification must be documented on the Appraisal Update and/or Completion Report (Form 1004D). The 1004D must confirm all “subject to” items listed on the appraisal were completed. If deviations have been made to the initial plans, the appraiser must note any impact to the value. If the value has been impacted, the lender must follow the policy in UnplannedChanges in Scope or Incomplete Work in B5-3.2-03, HomeStyle Renovation Mortgages: Collateral Considerations.
The lender must also obtain a certificate of occupancy upon completion of renovation if it is required by local authorities for the type of renovation work that was completed.
Title and Insurance Updates
Concurrent with the last disbursement of funds, the lender must obtain a title update through the date the renovation was completed, to ensure the continuance of Fannie Mae’s first lien priority and the absence of any mechanic's or materialmen’s liens. When the property is located in a state in which contractors’, subcontractors’, or materialmen’s liens have priority over mortgage liens, the lender must obtain all necessary lien releases or take any other action that may be required to ensure title to the property is clear of all liens and encumbrances.
The lender also must retain in the loan file a certification regarding the adequacy of the property insurance following completion of the renovation. The certification must confirm the coverage has been increased, if necessary, to comply with Fannie Mae’s standard property and flood insurance requirements.
