To fill out a construction job completion form, use the AIA G704 Certificate of Substantial Completion: enter the project description and exact substantial completion date, attach a punch list with a dollar estimate for the remaining work, spell out who handles maintenance, utilities, and insurance from that date forward, identify any warranties that start on a different date, and collect signatures from the owner, architect, and contractor. Each entry has downstream consequences for warranties, insurance, retainage, and lien deadlines, so the form deserves more care than its one-page length suggests.
Know Which Completion You’re Documenting
The G704 documents substantial completion, not final completion, and using the wrong milestone creates problems that follow the project for months.
Substantial completion means the project is finished enough for the owner to occupy or use the space for its intended purpose, even though minor punch list items remain. Once the certificate is issued, the owner takes responsibility for the property, warranty periods begin, and the process of releasing retainage payments starts.1AIA Contract Documents. Substantial Completion vs. Final Completion: Key Construction Milestones The local building department may also grant an occupancy permit at this point.
Final completion comes later, after every punch list item is resolved, all closeout documents are delivered, and the contractor has fulfilled every contractual obligation. Final completion triggers the release of remaining retainage and the final payment to the contractor.1AIA Contract Documents. Substantial Completion vs. Final Completion: Key Construction Milestones A separate closeout process handles final completion; the G704 is not that document.
Information to Gather Before You Start
Pull these records together before you sit down with the form. Hunting for contract numbers and dates mid-process leads to sloppy entries that delay recording and payment.
- Party names and addresses. The full legal names of the property owner, general contractor, and architect exactly as they appear on the original contract and permit filings. Mismatched names between the completion form and the recorded contract create identity errors at the recorder’s office.
- Project address and description. The street address and a clear description of the work performed, specifying whether the entire contract scope or only a designated phase is being completed.
- Contract details. The execution date of the prime contract and the contract number, if one exists.
- Punch list. A written list of every minor item still needing correction or completion, along with a cost estimate for that remaining work. The architect typically prepares this list after a walkthrough.
- Date of substantial completion. The specific calendar date the project reached the point where the owner could use it. This date drives warranty start times, lien deadlines, and insurance transitions, so getting it right is worth more attention than most people give it.
Filling In the AIA G704
The G704 is a one-page form available through AIA Contract Documents. Other templates exist, but most follow the same structure, so this walkthrough applies broadly.
Project Description and Date
After the opening paragraph, the architect inserts a detailed description of the project or the specific portion that has reached substantial completion. The architect then signs and dates the form at this section to certify that the described work qualifies as substantially complete.2AIA Contract Documents. G704-2017, Certificate of Substantial Completion – Instructions This date is the single most consequential entry on the form. Warranties, lien filing windows, and insurance responsibilities all flow from it.
Punch List and Cost Estimate
The architect provides a list of items to be completed or corrected, sets target dates for finishing each one, and establishes a dollar estimate for the outstanding work.2AIA Contract Documents. G704-2017, Certificate of Substantial Completion – Instructions The list is typically attached as a separate page. The cost estimate feeds directly into retainage calculations, because the owner uses it to determine how much to hold back until every punch list item is closed out.
Be specific. Vague descriptions like “finish trim work” invite disagreements later about what was and wasn’t included. Room numbers, fixture types, and finish specifications belong in the entries.
Responsibilities for Maintenance, Utilities, and Insurance
The G704 has a section where the parties spell out who handles maintenance, heat, utilities, property damage, and insurance from the date of substantial completion forward.3AIA Contract Documents. G704: Certificate of Substantial Completion The form itself notes that each party’s legal and insurance counsel should review these arrangements.4The American Institute of Architects. AIA Document G704 – 2000 Certificate of Substantial Completion
This section is where disputes most often originate. A gap in insurance coverage during the handoff period can leave damage uninsured, and if the contractor is still on site finishing punch list work while the owner has taken possession, both parties need active coverage. Write out who carries what, in plain terms, rather than leaving it to be inferred later.
Warranty Commencement
Warranties required by the contract start on the date of substantial completion listed on the form. If any specific warranties need to start on a different date, such as equipment warranties that begin at installation, identify them in this section with their alternative start dates.2AIA Contract Documents. G704-2017, Certificate of Substantial Completion – Instructions Leaving the section blank defaults every warranty to the substantial completion date, which can shorten or lengthen coverage on individual systems in ways nobody intended.
Signatures
The owner, architect, and contractor all sign and date the form at their respective signature lines.4The American Institute of Architects. AIA Document G704 – 2000 Certificate of Substantial Completion All three signatures are needed for the certificate to take effect. If your jurisdiction requires the document to be recorded, check whether your local recorder’s office accepts digital signatures or requires wet ink on paper. Requirements vary, and some offices still reject electronically signed documents.
Delivering the Form and Handling a Reluctant Signer
Once the signatures are in place, the form needs to reach every interested party: owner, contractor, architect, and in some cases the surety company. The delivery method matters because it establishes proof of when each party received the document, and that date starts various statutory clocks.
Certified mail with a return receipt requested gives you a physical record of the exact delivery date. That receipt becomes important evidence if a dispute arises about when the notification period began. Many modern contracts instead require submission through a project management platform, which provides an automatic time-stamped record of delivery. Either way, retain your delivery confirmation. A completion certificate that was “definitely sent” but can’t be proven received is almost as bad as one never sent at all.
If an owner is reluctant to sign the certificate, the contractor’s leverage is limited. Most contracts include duty-to-proceed clauses that require the contractor to keep working during disputes, and threatening to walk off the job can be treated as a breach of contract. The better approach is to request that the architect make an independent determination of substantial completion, since the G704 is issued by the architect rather than negotiated between the parties. If the architect certifies substantial completion and the owner still refuses to accept it, the contractor’s remedies are typically found in the contract’s dispute resolution provisions.
What the Completion Date Sets in Motion
The substantial completion date entered on the form starts two separate legal clocks that limit how long the contractor remains responsible for the work, which is why the date deserves careful attention rather than a rounded guess.
Warranty periods are the shorter of the two. On federal construction projects, the standard warranty runs for one year from final acceptance, and any repaired or replaced work carries its own one-year warranty from the date of that repair.5Acquisition.GOV. 52.246-21 Warranty of Construction Private contracts generally follow a similar one-year workmanship warranty, though manufacturer warranties on equipment and building systems often run longer. Those longer warranties should be individually identified on the completion form, since their start dates may differ from the general warranty commencement.
Statutes of repose set an outer boundary on liability that runs regardless of when a defect is discovered. Unlike a statute of limitations, which starts when someone discovers a problem, the statute of repose starts from a fixed event, usually substantial completion, and cannot be extended. Across the states, construction statutes of repose range from roughly 4 to 15 years. Once that period expires, a lawsuit over construction defects is barred even if the defect was hidden and only recently surfaced. Pushing the substantial completion date even a few weeks in either direction shifts the expiration of the contractor’s exposure by the same amount.
The date also drives the financial side. Substantial completion begins the process of releasing retainage that the owner has withheld from progress payments, typically 5% to 10% of the contract price. State laws govern the timeline: some require release within 30 days of final approval, while others allow up to 45 or 60 days. On federal projects, the Prompt Payment Act sets the interest rate at 4.125% for the first half of 2026 on late payments.6Bureau of the Fiscal Service. Prompt Payment Enter the date the project actually became usable, not the date the paperwork happened to reach the architect’s desk.
