Construction, the Design Appendix, and getting to 8609 — Montana

The calendar you're actually running, one Award-year ahead

This phase starts once MBOH sends the Reservation Agreement after an Award — and everything downstream runs off the calendar year after that Award, not the Award year itself. For a hypothetical 2026 Award, the Owner returns the signed Reservation Agreement by March 1, 2027; submits the Carryover Allocation package (Proof of Ownership, executed and recorded Restrictive Covenants, and the Reservation fee) by December 1, 2027; and gets the executed Carryover Allocation Agreement back to MBOH by December 31, 2027 (2027 QAP Section X.A–B).

Two things follow from that structure. First, the 10% test's 12-month clock is pinned to the date MBOH executed the Carryover Allocation Agreement — not the date the Owner submitted the package, and not a fixed calendar date tied to the Award. Get the actual execution date from MBOH; don't back into it from your own submission date. Second, nothing in Section X restates the federal placed-in-service deadline the way Arkansas's and Missouri's compliance manuals do for their own developers — Montana's QAP is silent on it entirely. Track IRC §42(h)(1)(E)(i) directly against your Carryover Allocation year rather than expecting MBOH's own document to repeat the federal rule.

No published or practitioner-reported range for Montana-specific construction or lease-up durations was located in this research. Schedule this phase against your own deal history and the actual dates in your project's Reservation Agreement, not an imported benchmark from a larger state.

The 10% test: total forfeiture, not a point deduction

The Owner must submit certification and related documentation demonstrating the federal 10% test under Section 42 no later than the first anniversary of the date MBOH executed the Carryover Allocation Agreement. The QAP's own language leaves no room for a partial consequence: "Failure to submit any required documentation, pay the required fee, submit certification for 10% documentation, or meet the 10% Test will cause forfeiture of Awarded, reserved or allocated Housing Credits" (2027 QAP Section X.C). Arkansas's 2027 QAP runs a tiered Past Performance and Non-Compliance point-deduction schedule for missed deadlines that follows a sponsor into future applications; Montana skips the point system for this particular milestone and goes straight to forfeiting the Credits themselves.

Montana's answer to a stalled deal isn't Arkansas's Credit Swap — it's a Credit Refresh (2027 QAP Section X.E): converting Credits already awarded from their original Credit year to a more recent one, available to any Project that has an executed Carryover Allocation and an MBOH-approved 10% Cost Certification. Unlike Arkansas's 2027 gate, which now requires the 10% test to be complete and construction to have started before a Credit Swap can even be requested, Montana's Credit Refresh runs on a straightforward Board vote weighing named factors — the Development Team's diligence, any factors beyond its control, the likelihood the Project will be completed if approved (or won't be, if denied), and the continuing need for the Project. The amount refreshed can't exceed what was originally awarded or the Applicable QAP's maximum Credit Award, and once approved, all requirements of the Applicable QAP apply to the refreshed Reservation as if it were the original.

The Design Appendix is the real construction-quality checkpoint

Most states hang construction quality entirely off local building code. Montana's QAP carries its own Design Requirements appendix (Appendix B) — baseline code compliance, then accessibility, adaptability, durability, energy, and environmental standards layered on top, all enforced by a signed architect and Owner certification MBOH requires before Final Allocation. The appendix applies to every current Application and to every Project awarded Credits under a QAP for 2025 or later, and a developer can request a written waiver of any individual item on a substantial-good-cause showing, subject to MBOH's discretion to deny it.

Certification closes the loop: "Upon Project completion, the architect and the Owner must each certify the Project by providing their signature on their letterhead per the MBOH Architect Certification within the Proforma (Excel) that indicates all mandatory and discretionary work is completed and installed. If the Owner has hired a third party, that party must certify." That certification, along with the blower-door or infrared test report where applicable, is a separate step from ordinary construction-completion paperwork — and it happens before Final Allocation, not after.

Getting to Form 8609

The same LURA that clears the path to 8609 also settles a decision most developers don't expect to make this early: by executing it, the Owner waives the right to ever ask MBOH to locate a nonprofit qualified buyer under the Qualified Contract Process, and agrees the Extended Use Period "may not be terminated early through the Qualified Contract Process" for the full 50-year term (2027 QAP Section X.D). That waiver — and what it actually forecloses at Year 15 — is covered in the next phase, but it's worth knowing it gets signed here, at 8609, not fifteen years from now.

Substantial Changes and quarterly reporting keep MBOH in the loop through completion

MBOH must specifically approve a long, named list of "Substantial Changes" before implementation, and the Applicant must notify MBOH in writing at least 30 days before implementing any of them (2027 QAP Section X.H). The list runs well past major scope changes — it reaches a Development Team member change, the Developer Fee or Consultant Fee agreement, quality or durability of construction, unit count or composition, site or floor plan, square footage, income or rent targeting, target group, project location, a Sources-and-Uses line-item shift of 10% or more, the Extended Use Period itself, and anything that would have lowered the Development Evaluation Criteria score or failed a mandatory threshold. Separately, MBOH must approve any implementation-schedule change greater than 60 days. If MBOH staff denies a Substantial Change request, the Applicant may take it to the Board.

Quarterly Reports (2027 QAP Section XI) are due by the 10th day of every calendar quarter and apply, in the QAP's own words, "to all Projects that have an award of credits" — the text doesn't specify an end date. Treat the requirement as running at least through placed-in-service and confirm with MBOH whether it continues past 8609 issuance rather than assuming it stops there. Late reports draw a fine under the Fee Schedule.
