"MaineHousing caps my Total Development Cost with some formula that blends per-unit and per-bedroom costs, caps my contractor's fee separately from my own developer fee, and has its own cold-climate energy specs on top of the state building code -- and does any of this trigger prevailing wage?"
The Total Development Cost Index: a cost-reasonableness formula unique to Maine
Rather than a single per-unit cost cap, Chapter 16 evaluates cost reasonableness through a weighted "TDC Index": the weighted average of a project's Total Development Cost per unit and its Total Development Cost per bedroom, calculated as ([2 x TDC/unit] + [TDC/bedroom]) divided by 3. For a mixed-use project, only the residential portion (including common areas) is used. An Application is rejected outright if its TDC Index exceeds the applicable cap at any point up to the later of construction-loan closing or the carryover allocation -- meaning cost overruns discovered mid-process, not just at Application, can disqualify a Project.
| Project type | 2027 TDC Index Cap | 2028 TDC Index Cap |
|---|---|---|
| Adaptive reuse | $414,750 per unit | To be set -- MaineHousing will review the New England Consumer Price Index and adjust accordingly |
| New construction | $388,500 per unit | Same CPI-indexed adjustment |
| Acquisition and rehabilitation of existing housing | $357,000 per unit | Same CPI-indexed adjustment |
Demolition-and-reconstruction is treated as new construction. A project mixing types uses a caps average weighted by unit count of each type.
"Total Development Cost" itself is a defined, engineered figure, not simply total project cost: it equals Total Project Cost minus (1) MaineHousing's own required fees, (2) the Project's operating deficit escrow to the extent MaineHousing requires it, (3) costs tied to any commercial space, and (4) up to $20,000 per unit of Additional (deferred) Developer Fee. "Total Project Cost," in turn, is the broader figure -- acquisition costs, capitalized lease value, demolition, Total Construction Cost, construction contingency, soft costs, syndication costs, Developer Fee, financing costs, and project reserves, all as determined by MaineHousing. The gap between these two defined terms is exactly the deferred Additional Developer Fee carve-out described below -- a project can push up to $20,000/unit of deferred fee outside the TDC Index calculation entirely.
Developer fee and general contractor cost caps -- and which one a bond deal escapes
Chapter 16 separately caps what the developer keeps and what the general contractor's overhead and markup can be. The Maximum Developer Fee is the sum of 15% of Housing Development Costs plus 10% of acquisition costs (land, existing buildings, and equipment), figured without regard to the fee itself. The portion that is not deferred -- the Net Developer Fee -- cannot exceed $750,000, plus any unused construction contingency returned to the Applicant after completion. A project can go beyond that only through a deferred Additional Developer Fee, capped at $20,000 per LIHTC unit and excluded from the TDC Index calculation, used either to increase tax credit equity or to reduce taxable surplus-cash distributions to the syndicator; any deferred fee cannot be interest-bearing or mortgage-secured.
The general contractor's own compensation is capped separately and must be broken out from actual construction costs: General Contractor Intermediary Costs -- general conditions plus overhead and profit -- cannot exceed 14% of Total Construction Cost in total, within sub-limits of up to 6% for general conditions and up to 8% for overhead and profit.
| Cap | Applies to a bond-financed 4% Project? | QAP reference |
|---|---|---|
| Developer Fee limits (Section 7.B) | No -- Section 9.H exempts bond deals | Section 9 |
| TDC Index Cap (Section 5.B) | Yes -- not on Section 9's exemption list | Section 9 |
| GC Intermediary Cost cap (Section 7.C) | Yes -- not on Section 9's exemption list | Section 9 |
| $75,000/unit minimum rehabilitation cost (Section 5.C.2) | No -- Section 9.F exempts bond deals | Section 9 |
A bond-financed 4% deal escapes the QAP's own Developer Fee ceiling and the acquisition/rehab minimum-spend rule, but not the TDC Index or the general contractor's cost caps -- an easy distinction to get backwards.
Maine's cold-climate construction standards: MUBEC plus MaineHousing's own component minimums
Chapter 16 makes compliance with "MaineHousing's Construction Standards" a mandatory threshold requirement for every Project (Section 5.I), defined as MaineHousing's own Quality Standards and Procedures Manual, which the QAP itself describes as including, without limitation, "certain energy efficiency standards and UPCS." The current (2026) edition of that manual sets Maine's Uniform Building and Energy Code (MUBEC) -- which incorporates the International Energy Conservation Code -- as MaineHousing's baseline building code, then layers its own, more specific minimum energy-conservation standards on top for new construction.
Notably, the QAP's own Appendix A defines "Passive House Certification" (PHIUS or PHI certification obtained before MaineHousing issues IRS Form 8609) as a defined term, but this research could not find that defined term actually invoked anywhere else in the current QAP's threshold or scoring sections, or in the Quality Standards and Procedures Manual -- it appears to be a definition without a currently operative requirement or scoring point attached to it. A developer should not assume Passive House certification is required, encouraged, or scored in Maine's current cycle based on this defined term alone; confirm directly with MaineHousing whether it is tied to any current or planned requirement. Separately, Section 6.C of the QAP does award one scoring point for pledging that at least 50% of a building's exterior thermal envelope square footage will use wood fiber insulation specifically, unless MaineHousing agrees that cost or supply-chain constraints make it infeasible.
Prevailing wage: a real state law, but a narrower trigger than "any LIHTC deal" -- plus federal Davis-Bacon's separate switch
Maine has its own general prevailing-wage statute, 26 M.R.S. Chapter 15 ("Preference to Maine Works and Contractors"), administered by the Department of Labor's Bureau of Labor Standards, which surveys and sets prevailing hourly wage and benefit rates annually (the Department published its 2026 rates effective January 10, 2026). But the statute's own trigger is narrower than "any project that receives LIHTC": it applies to "public works," which §1304(8) defines as buildings and other listed structures "upon which construction is funded in whole or in part by state funds and for which the contract amounts to $50,000 or more." Tax-exempt bond proceeds, LIHTC equity, and ordinary private debt are not, by themselves, "state funds" under this definition -- a purely privately- and bond-financed Maine LIHTC deal, with no direct state appropriation in its capital stack, does not appear to be "public works" under Chapter 15's own text.
The complication is MaineHousing's own 0% interest deferred debt, a routine piece of the capital stack on many Maine LIHTC deals. Its funding sources include not only federal pass-through dollars (federal HOME funds, National Housing Trust Fund dollars) but also the state-legislature-funded Housing Opportunities for Maine Program (the "HOME Fund" under 30-A M.R.S. §4853, capitalized by a share of Maine's real estate transfer tax) and other state appropriations MaineHousing may direct to a project. This research could not confirm, from any primary source reviewed, whether the Bureau of Labor Standards or MaineHousing itself treats that state-legislature-appropriated deferred debt as "state funds" sufficient to make an otherwise privately-financed LIHTC project "public works" under Chapter 15 -- neither the QAP, the Rental Loan Program Guide, nor Chapter 15 itself directly addresses the question. A developer whose deferred-debt award is state-sourced should raise this directly with MaineHousing and, if needed, the Bureau of Labor Standards, rather than assume either way.
Federal Davis-Bacon: an independent trigger through HOME and the National Housing Trust Fund
Separately from Maine's own state law, federal Davis-Bacon prevailing wage requirements attach independently whenever a project uses federal HOME Investment Partnerships Program funds (24 CFR Part 92) or National Housing Trust Fund dollars (24 CFR Part 93) -- both of which MaineHousing itself channels into LIHTC deals through its Rental Loan Program's 0% deferred debt and through the QAP's own National Housing Trust Fund scoring category (Section 6.G), which ties a subset of Credit Units to Project-Based Vouchers and a federal Part 58 or Part 93 Environmental Review. This federal trigger operates on its own terms regardless of whether Maine's own Chapter 15 state prevailing-wage law applies to the same project -- a deal can be subject to Davis-Bacon through its HOME/NHTF funding even where Chapter 15's own "state funds" test is unresolved or does not clearly apply.
Two additional federal labor-and-materials requirements apply "when applicable" under the QAP's own Project Design and Construction Requirements (Section 5.I): the Build America, Buy America Act's domestic-content procurement preference for iron, steel, manufactured products, and construction materials (Pub. L. 117-58; 2 CFR Part 184), and Section 3 of the Housing and Development Act of 1968 (12 U.S.C. §1701u; 24 CFR Part 75), which requires HUD-assisted projects to direct training, employment, and contracting opportunities to low- and very-low-income persons and Section 3 businesses to the greatest extent possible.
Where this goes wrong
- Treating Maine's TDC cap as a flat per-unit number -- it is a weighted index combining per-unit and per-bedroom Total Development Cost (([2 x TDC/unit] + [TDC/bedroom]) / 3), evaluated against a cap that varies by project type and is checked again at construction-loan closing or carryover, not just at Application.
- Confusing "Total Development Cost" with "Total Project Cost" -- TDC is Total Project Cost minus MaineHousing's required fees, the operating deficit escrow, commercial-space costs, and up to $20,000/unit of deferred Additional Developer Fee; using Total Project Cost against the TDC Index Cap will overstate the number that actually gets tested.
- Assuming a tax-exempt-bond-financed 4% Project is exempt from the TDC Index Cap or the general contractor's cost caps because it is exempt from the Developer Fee limit -- Section 9's exemption list covers Developer Fee (7.B) and the rehab-spend minimum (5.C.2), but not the TDC Index Cap (5.B) or the GC intermediary cost cap (7.C).
- Sizing the general contractor's total intermediary costs without separating general conditions from overhead and profit -- the 14% overall cap is composed of two sub-caps (up to 6% general conditions, up to 8% overhead and profit), not one blended number.
- Assuming Passive House Certification is a current MaineHousing requirement because it is a defined term in the QAP's Appendix A -- this research could not find it tied to any operative threshold or scoring provision in the current QAP or Quality Standards Manual; confirm directly with MaineHousing before budgeting for it.
- Assuming Maine's own prevailing-wage law (26 MRS Chapter 15) applies to every LIHTC project the way federal Davis-Bacon applies whenever HOME or NHTF funds are used -- Chapter 15's own "public works" definition requires the project to be funded in whole or in part by state funds on a contract of $50,000 or more, which a purely bond- and equity-financed deal may not meet.
- Assuming MaineHousing's own state-sourced 0% deferred debt (funded in part by the state-appropriated Housing Opportunities for Maine Program) can never trigger Maine's Chapter 15 prevailing wage -- this research could not confirm the opposite either; it is an open question that should be raised directly with MaineHousing and the Bureau of Labor Standards.
- Treating the Build America, Buy America Act and Section 3 requirements as optional best practices -- the QAP applies both "when applicable," which for most federally-assisted Maine LIHTC deals means they are mandatory, not discretionary.
- Assuming MaineHousing's minimum energy standards are satisfied by meeting the state's baseline MUBEC/IECC code alone -- MaineHousing layers its own more specific component minimums (R-60 roof, R-38 floor, Energy Star 7.0 glazing, mandatory blower-door testing) on top of the code as an independent threshold requirement.
