"What does it cost, and which ADFA ceiling is actually going to bind?"
Four passes, and where Arkansas actually locks the number
The four-pass structure — napkin, concept estimate, application budget, final reconciliation — is universal to the industry and applies in Arkansas unchanged. What differs is which document holds the locked number and how much discretion the agency keeps over it.
| Pass | Who produces it / Arkansas document | Precision | Timing |
|---|---|---|---|
| Napkin / screening estimate | Developer's own model, in Excel | ±30–40% | Minutes to hours |
| Concept estimate | Architect's SD set priced by GC preconstruction or a third-party estimator | ±15–20% | Weeks after schematic design |
| Application budget | ADFA's Multifamily Housing Application (MFHA) Development Cost Schedule, backed by the Hard Construction Cost Breakout ("Summary Cost Estimate" form, QAP §32) | Locked at the Application Deadline | First Monday of February |
| Final Cost Certification | CPA-audited cost report, required at closeout on both 9% and 4% deals | Final — Arkansas's placed-in-service true-up | Reconciled against the fee caps and per-unit limits before Form 8609 issuance |
Two structural notes before anything else. Arkansas runs a single annual competitive 9% cycle — application deadline the first Monday of February, scoring notice the third Friday of April, reservations approved the third Thursday of May (QAP Part I.B) — while 4% Housing Tax Credit/bond applications are accepted year-round and simply expire, unreviewed, six months after submission unless ADFA's Staff Housing Review Committee has by then approved them and recommended them for approval to the Board Housing Review Committee (QAP §33). And ADFA keeps a discretionary override the scored process doesn't fully constrain: "ADFA has the discretion to determine reasonableness of all costs and may deny an Application based upon the unreasonableness of costs regardless of whether such costs are within the limits stated herein" (QAP §14).
Who is actually in the room tracks the other states' cast — developer project manager, architect, GC preconstruction estimator, LIHTC consultant — with one Arkansas-specific difference: a labor-compliance specialist only joins when RD Section 516 grant funds, 12-or-more HOME-assisted units, or an 8-or-more-unit CDBG rehab are actually in the stack. Never by default, because Arkansas itself imposes no general prevailing-wage requirement of its own.
Two governing numbers, and neither works like a high-cost test
Arkansas does not run a percentage-over-a-basis-limit kill switch the way CTCAC does. It runs two independent, harder-edged numbers instead: a scored cost-per-unit curve for the competitive 9% round, and a flat per-unit dollar ceiling for bond-financed 4% deals.
| Total development cost per unit | Points |
|---|---|
| Under $210,000 | 15 |
| $210,000–$219,999 | 12 |
| $220,000–$229,999 | 9 |
| $230,000–$239,999 | 7 |
| $240,000–$249,999 | 5 |
| $250,000–$259,999 | 2 |
| $260,000 or more | 0 |
The denominator is "the entirety of uses listed divided by the number of units (including for employees)" — every source and use in the application, not eligible basis alone, and every unit including manager/employee units.
Losing all 15 points here doesn't disqualify a 9% application the way breaching CTCAC's 30% gate ends a California cycle. But against a 75-point minimum score to even be eligible for 9% credits (QAP §31), giving up the full band is real point-margin that has to be rebuilt elsewhere in the scoring matrix.
The bond side is where the number stops being a curve and becomes a wall: "ADFA will limit the per-unit total development cost of developments receiving 4% LIHTCs in connection with tax-exempt bond financing to $300,000" (QAP §14). The QAP text publishes no waiver path around it.
| Bedrooms | Single-family detached / all other new construction | Acquisition/rehabilitation |
|---|---|---|
| 0–1 BR | $19,365 | $13,285 |
| 2 BR | $20,790 | $15,015 |
| 3 BR | $21,945 | $17,325 |
| 4 BR | $23,100 | $18,480 |
A third ceiling sits above both: no single development may receive more than $1,300,000 of the year's federal 9% credit ceiling (QAP Part III.C) — a hard cap on deal size by credits, independent of how the per-unit cost numbers pencil. ADFA also retains a discretionary lever CTCAC's certified boost menu doesn't have an equivalent for: it may increase a building's eligible basis by up to 30% "to the extent the Authority determines that any building requires an increase in LIHTCs in order for such building to be financially feasible" (QAP Part III.A) — a case-by-case underwriting judgment, not a menu of certifiable, self-executing boosts.
The contractor-fee ceiling has a scoring bonus stacked on top of it
Where California caps builder overhead, profit and general requirements as one blended 14% number, Arkansas splits it into three separately capped lines — and then layers a second, tighter set of the same three lines into the scoring matrix as an optional bonus.
| Line item | Cap | Base |
|---|---|---|
| General Requirements | 7% | Construction hard costs |
| Contractor's Profit | 10% | Construction hard costs plus General Requirements |
| Contractor's Overhead | 4% | Construction hard costs plus General Requirements |
| Condition | Points |
|---|---|
| General Requirements not exceeding 6% of construction hard costs | 1 |
| Contractor's profit not exceeding 8% of hard costs plus General Requirements | 1 |
| Contractor's overhead not exceeding 3% of hard costs plus General Requirements | 1 |
| Meeting all three of the above | +2 (5 total) |
A GC contract negotiated only to the §13 regulatory floor is not the same contract as one chasing the Item 4 scoring bonus. The gap between 7%/10%/4% and 6%/8%/3% is a real negotiation, not a rounding difference, and it has to happen before the MFHA is locked, not after.
Developer fee runs on its own cap: 10% of Net Development Costs for a 9% competitive award, or 12.5% for a deal receiving credits from tax-exempt bond financing, inclusive of developer overhead, profit and consultant fee (QAP §12a). Deferral is capped tighter than in many states — no more than 50% of the maximum allowable fee, payable by the earlier of 15 years or the equity investor's/lender's own deadline (QAP §12b).
Rehabilitation carries a cost floor most developers don't expect: hard costs (labor and materials) must be at least $50,000 per unit and at least 30% of total development cost, and a development in a federally designated floodplain or floodway is not eligible for rehabilitation consideration at all (QAP §16). A scope that's too thin fails threshold the same way one that's too expensive fails it elsewhere.
No state prevailing wage law — the labor package rides entirely on the federal dollars in the stack
Arkansas has no general state prevailing-wage statute — nothing plays the role California Labor Code §1720 plays as the central axis of this phase. The Arkansas Department of Labor and Licensing runs no state prevailing-wage determination program, and Title 22 of the Arkansas Code (Public Property), including its own Public Works chapter (Chapter 9), carries no wage-rate requirement of general application. Absent a federal trigger, an Arkansas LIHTC contractor prices the job at market rates.
| Program | Trigger | Citation |
|---|---|---|
| HOME | Construction contract covering 12 or more HOME-assisted units | 24 CFR §92.354(a)(1) |
| CDBG | Rehabilitation of residential property with not less than 8 units | 24 CFR §570.603(a) |
| Public Housing / RAD | No unit threshold | U.S. Housing Act of 1937 |
The distinction that actually matters most in Arkansas sits inside USDA Rural Development, which finances a disproportionate share of the state's rural LIHTC pipeline. Section 515 Rural Rental Housing — the standard family/elderly RD loan paired with LIHTC across most of rural Arkansas — carries no Davis-Bacon wage requirement in its governing construction regulation. Section 516 Farm Labor Housing grants are the opposite case: "Construction financed with the assistance of a Section 516 grant will be subject to the provisions of the Davis-Bacon Act..., and the implementing regulations published by the Department of Labor at 29 CFR parts 1, 3, and 5" (7 CFR §3560.559(c)). A Section 514 loan paired with a 516 grant on the same off-farm labor housing project pulls the whole construction contract onto Davis-Bacon wages the moment the grant is present; a standard Section 515 family or elderly deal does not.
Get this backwards in either direction and the budget is wrong by a real margin. Treat a Section 515 deal as prevailing wage and General Requirements is overstated for no reason; treat a 514/516 farm labor housing deal as market-rate and the GC discovers Davis-Bacon at bid time, months after the application budget was locked.
Build America, Buy America now runs through ADFA's own Design Standards Manual
ADFA's Design Standards Manual for New Construction and Rehabilitation — approved by the ADFA Board on July 16, 2026 — now carries its own section on domestic sourcing. Section 13 states that the Build America, Buy America Act "requires any infrastructure project funded by any Federal Financial Assistance to apply a domestic content procurement preference," meaning "all iron, steel, manufactured products, and construction materials used in the infrastructure project are to have been produced in the United States, unless the awarding agency has issued a waiver of this requirement" — citing Title IX of the Infrastructure Investment and Jobs Act.
For an ADFA-administered development, that Federal Financial Assistance trigger means HOME and National Housing Trust Fund dollars specifically — not a stand-alone LIHTC allocation, which is a tax expenditure rather than a federal award. A HOME-funded deal at 12 or more assisted units now carries two federal layers at once: Davis-Bacon wage rates on the labor, and Buy America sourcing on the materials. The wage side has decades of established Arkansas compliance practice behind it; the sourcing side is new enough in 2026 that most GCs bidding Arkansas HOME/NHTF work have not yet built it into standard procurement, and neither the waiver process nor its practical cost impact has an established track record yet.
Design-standard cost floors with no basis-limit offset to absorb them
Arkansas runs no threshold-basis-limit system, which means it also has no CTCAC-style boost menu that trades a certified feature for extra eligible basis. Every mandatory design standard is simply an unabsorbed add against the same TDC-per-unit scoring band described above.
| Unit type | Minimum net square footage | Minimum bathrooms |
|---|---|---|
| 1 BR / 1 BA | 600 SF | 1 |
| 2 BR / 1.5 BA | 750 SF | 1.5 |
| 2 BR / 2 BA | 1,000 SF | 2 |
| 3 BR / 2 BA | 1,100 SF | 2 (1.5 minimum) |
| 4 BR / 2 BA | 1,200 SF | 2 |
Studio units are prohibited outright on new construction and capped at 10% of unit mix on rehabilitation (§1.4.1). In-unit washer/dryer is mandatory on new construction, not just hookups (§1.4.2). All new and rehabilitated units must meet Energy Star standards for both the building and its appliances (§1.6).
Vertical circulation carries its own rule: any building with units above grade must provide covered access, and if the building is served by an elevator, that elevator must serve every unit in the building — there is no partial-elevator design option once one is installed (Design Standards Manual §2.1).
There is no single statewide building code edition to anchor a Type V-versus-Type III construction-type decision against. Construction must comply with "applicable federal, state, county, and local codes," and only "in the absence of local codes" does ADFA's own manual default to the International Existing Building Code, the National Standards for Physical Inspection of Real Estate (NSPIRE), and the 2024 International Energy Conservation Code (§1.3). In practice, which code edition governs a story-count or construction-type cost decision depends on what the specific city or county has adopted — information that has to be confirmed with the local building department on a site-by-site basis, not read off a single statewide table.
The order to run this in
| Step | Action | Why |
|---|---|---|
| 1 | Decide the RD/HOME/CDBG financing mix before anything else | This decision alone — not the site, not LIHTC itself — determines whether Davis-Bacon and Buy America apply at all |
| 2 | Confirm construction type and story count against the local building department's adopted code edition | There is no statewide default outside the IEBC/2024 IECC/NSPIRE baseline, which the manual applies only in the absence of local codes |
| 3 | Size units and specify features to the Design Standards Manual minimums, and price them as pure adds | There is no basis-boost menu in Arkansas to offset a mandatory feature against |
| 4 | Set the GC contract to the scoring-bonus GR/profit/overhead bands (6%/8%/3%), not just the hard caps (7%/10%/4%) | Needed if the extra 5 Item-4 points are required to clear the 75-point minimum score |
| 5 | Total every use of funds, divide by total units, and check that number against the TDC/unit band and, on bond deals, the $300,000 hard ceiling — in that order | The second check is not a matter of losing points; it is a stated ceiling with no published waiver path |
Those first three decisions are jointly determined the same way they are everywhere else — unit mix moves the TDC/unit denominator, construction type moves both hard cost and the code path, and financing choice moves the entire labor-and-sourcing question. Arkansas just resolves the answer through a scoring curve and a flat dollar ceiling instead of a percentage-over-basis-limit gate.
Where this goes wrong
- Assuming Arkansas runs a prevailing-wage regime and pricing General Requirements as if it does. The real risk runs the other direction here: a deal underwritten as market-rate quietly becomes Davis-Bacon-covered when HOME (12+ assisted units) or CDBG (8+ unit rehab) dollars get layered in after the initial budget.
- Confusing RD Section 515 with Section 516. A standard 515 family/elderly rental deal carries no Davis-Bacon requirement; a 514/516 farm labor housing grant deal does, by regulation (7 CFR §3560.559(c)). Pricing either one as if it were the other produces a wrong labor number in either direction.
- Treating the Item 9 TDC-per-unit scoring bands as a hard ceiling. Losing all 15 points doesn't disqualify the application — but recovering that margin against a 75-point minimum score is a real scoring problem, not a rounding error.
- Missing the $300,000 per-unit hard cap on 4% bond deals. Unlike the scored 9% curve, QAP §14 reads as an unconditional limit with no published waiver path in the plan text — model it as a wall, not a target to approach.
- Meeting the §13 hard caps (7%/10%/4%) but not the tighter Item 4 scoring bands (6%/8%/3%) that carry up to 5 points. A GC contract negotiated only to the regulatory floor leaves real points on the table.
- Underestimating the rehabilitation cost floor. §16 requires rehab hard costs of at least $50,000 per unit and at least 30% of total development cost — a thin, cosmetic scope can fail threshold for being too cheap. Floodplain or floodway sites are barred from rehab consideration outright in the same section.
- Not pricing Energy Star, mandatory in-unit washer/dryer, and the minimum-unit-square-footage table as straight adds. None of these carry a basis-limit boost to offset them in Arkansas's framework — they just push the TDC/unit number higher against the same scored band.
- Missing Buy America on HOME/NHTF-funded work. Newly written into ADFA's own Design Standards Manual (approved July 16, 2026, §13), it requires domestic-sourced iron, steel, manufactured products and construction materials on any ADFA-administered Federal Financial Assistance project, absent a waiver — and it stacks with Davis-Bacon on the same HOME dollars rather than replacing it.
- Assuming a single statewide building code edition exists. ADFA's own standards default to the IEBC/2024 IECC/NSPIRE baseline only "in the absence of local codes" — the construction-type and story-count rules that actually drive cost run through whichever code the local jurisdiction has adopted, confirmed city by city.
- Treating the published cost caps as the whole underwriting test. QAP §14 explicitly reserves ADFA's discretion to reject an application for unreasonable costs regardless of whether those costs sit within the stated limits — clearing every number on paper does not by itself clear underwriting.
- Ignoring the $1,300,000 per-development federal 9% credit cap when sizing a large deal. A project whose per-unit numbers pencil can still be capped in total size by this ceiling well before the per-unit TDC bands become binding.
- Deferring more developer fee than the QAP allows. The deferred portion cannot exceed 50% of the maximum allowable fee (§12b) — a tighter deferral ceiling than jurisdictions that permit deferring the full fee.
