"ADOH's QAP asks for almost nothing on site control -- so what actually has to be locked down before I spend real diligence money on an Arizona parcel?"
The QAP asks for comparatively little -- and that's the finding
In Low-Income Housing Tax Credit deals the subsidy arrives before the land closes, not after: the tax credit itself is the money that pays for the site, so developers option or contract for property years before they can actually close on it. That basic inversion holds in Arizona exactly as it does everywhere else.
What differs is how much the regulator makes you prove along the way. CTCAC devotes a page of regulation and four-plus accepted instruments to site control; TDHCA defines it with a 45-year minimum lease term and three tightly specified document types. The Arizona Department of Housing's (ADOH) Qualified Allocation Plan gives it a single paragraph.
| Track | Requirement |
|---|---|
| Non-tribal | A legally binding contract, in writing and signed by the current owner or by both the seller and buyer (or lessor and lessee), documenting either current ownership or the legal ability to purchase the real estate (which may be a long-term ground lease), in the name of the Applicant, a Principal, or an affiliated entity, and valid through at least one month after the anticipated award date. Acceptable forms: deeds, purchase agreements, purchase options, lease agreements, and lease options. |
| Tribal, lease not yet executed | An agreement between the ownership entity and the Tribe to enter a lease of at least 25 years with an option to renew for another 25 years, plus a Tribal (or TDHE) resolution authorizing that agreement; the agreement must state a rental amount and confirm the Tribe or TDHE will execute the LURA. |
| Tribal, lease already executed | Evidence the land is leased and that all necessary Tribal, Bureau of Indian Affairs, and other governmental approvals have been secured, with the same 25-year term, renewal option, rental amount, and LURA-execution terms; for land established by federal public law, documentation of that law as well. |
The 2026-2027 QAP tightened this from the 2024-2025 cycle: it now names five acceptable instrument types -- deeds, purchase agreements, purchase options, lease agreements, and lease options -- and requires the document be in writing and signed by the actual parties, not merely referenced or implied. But it still stops well short of CTCAC's page of regulation: no extension-ladder evidence requirement, no title-insurance-style "valid, current, enforceable" standard, and no requirement that the agreement survive the application deadline itself the way CTCAC's Section 10325(f)(2)(D) does -- only that it exists, names the right party, uses one of the listed forms, and runs one month past the date ADOH expects to make an award. That remains a genuinely lower regulatory bar than California's or Texas's, and it shifts most of the real diligence discipline onto whatever the lender or equity investor independently requires before they will fund.
ADOH runs the credit; the Arizona Finance Authority runs the bonds
Arizona doesn't split LIHTC administration across a housing-finance agency and a separate bond-allocation committee the way California splits CTCAC from CDLAC or Texas splits TDHCA from the Bond Review Board. One agency, ADOH, runs the QAP for both the 9% and 4% federal credits at once. Through 2025 it also administered the state's own affordable-housing tax credit (the STC) alongside them; that program's statutory sunset has since taken it out of the QAP entirely (more below).
A 4% deal still depends on a second entity, though. ADOH will not issue an I.R.C. Section 42(m) Determination of Qualification of Tax Credits letter for a bond-financed 4% application until the deal has a confirmed Private Activity Bonding Authority Volume Cap Allocation from the Arizona Finance Authority.
| Step | Requirement |
|---|---|
| Before ADOH will act | An Issuer's Delegation of Determination Letter and a bond inducement resolution, an ADOH Bond Certification Form, plus the 4% LIHTC application and supporting documentation |
| What has to be confirmed first | A Private Activity Bond volume cap allocation from the Arizona Finance Authority |
| Bond issuance limitation (new in 2026-2027) | Volume cap allocated to the project may not exceed the greater of 30% of the project's aggregate eligible basis (I.R.C. Section 42(d)) or the amount needed to support the project's maximum permanent debt -- a project that exceeds this at 42(m) review is ineligible for the 4% allocation |
| ADOH's own decision clock | No published turnaround commitment -- the 2024-2025 QAP's "no more than 30 days from a properly documented submission" language does not appear in the 2026-2027 text |
| Award method | First come, first served, among complete applications ("contains only de minimis errors or omissions") -- 4% is not scored |
No published Arizona Finance Authority volume-cap allocation calendar surfaced in the research, so unlike Texas's fixed December 1 / March 1 earnest-money dates on a Bond Review Board lottery, there is no verified fixed date here to plan a 4% deal's site-control ladder around -- and as of the 2026-2027 QAP, ADOH no longer commits itself to a review-time clock either. Treat both the Arizona Finance Authority allocation and ADOH's own review time as unscheduled external dependencies to confirm directly with those agencies, not as dates to carry forward from a prior round.
One note on the money that used to be layered on top of this: S.B. 1124 (2021) created the STC, letting ADOH allocate up to $4 million a year in state tax credits under A.R.S. Section 41-3954, claimed by taxpayers against income, premium, or insurance tax under A.R.S. Sections 43-1163, 43-1075, or 20-224.04. Both the administering statute (Section 41-3954) and the credit-claim statute (Section 43-1163) carry an identical delayed-repeal clause -- each "is repealed from and after December 31, 2025." The 2024-2025 QAP flagged the program as "currently set to sunset"; the 2026-2027 QAP confirms it took effect on schedule -- the STC has no selection-criteria section, no application schedule, and no scoring mechanism anywhere in the current document. Do not build it into a capital stack for a new application; it now matters only for servicing credits already allocated under earlier awards.
No title-report clock, because the QAP doesn't set one
This is the most surprising absence in the document. CTCAC gives title reports a 90-day freshness window, CDLAC runs a parallel 90 days, HCD MHP tightens it to 30, and TDHCA requires one dated within 6 months of the deadline. A full-text search of Arizona's QAP for "title report" and "title insurance" returns nothing in either the 2024-2025 Final QAP or the 2026-2027 QAP's Third Draft (Dec. 2025) -- no dated deliverable, no freshness window, no threshold document of that kind at all, across two full drafting cycles.
That's a real finding, not a research gap: the QAP's entire site-control test, Section IV(A)(7), is satisfied by the ownership or purchase-ability documentation itself, with nothing in the document layering an independently dated title report on top of it.
It does not mean title work is optional. The lender, the equity investor, and the title company that has to insure the deal and let a LURA record against the parcel will all still demand clean, examined title on their own schedule -- Arizona simply doesn't give that schedule a regulatory clock the way California and Texas do. Treat the absence of a QAP deadline as one fewer date to track, never as one fewer document to order.
The appraisal: six months, one number, and ADOH's own second opinion
Where the three-regulator California stack keys the appraisal window to the site-control execution date, Arizona keys it to the application deadline directly.
Exhibit B then splits the acquisition-specific requirements by deal type.
| Deal type | Requirement |
|---|---|
| New construction | A land-only appraisal of real property not subject to a lease |
| Acquisition/rehab or adaptive reuse | Separate land and building values; scattered-site single-family projects must separately value and inspect at least 25% of each unit type and condition |
| Tribal | Cost-based appraisals may use HUD's Valuation Analysis for Single Family One to Four Unit Dwellings (Directive 4150.2), applying a 45-year economic life for framed houses and 50 years for masonry, with Marshall and Swift life-expectancy and replacement-cost estimates |
The mechanism worth planning around is validation. If ADOH doesn't accept the submitted appraisal in its own sole discretion, it selects a second appraiser at the Applicant's expense and uses whichever of the two values is lower for underwriting -- ADOH controls the tiebreak, and it is present at every inspection tied to that second appraisal. A strong appraisal from the Applicant's own appraiser doesn't lock in a number the way it might in a jurisdiction without this override.
Phase I is a rehabilitation rule on the page
Exhibit A's mandatory design standards separate new construction from rehabilitation, and the explicit environmental-assessment requirement lives only on the rehabilitation side.
| Project type | Requirement | Citation |
|---|---|---|
| New construction | A geotechnical investigation report by an Arizona-registered engineer; no explicit Phase I Environmental Assessment requirement appears in the QAP text | Exhibit A Section IX(A)(1) |
| Rehabilitation | A Phase I Environmental Assessment, plus a Hazardous Materials Study (asbestos and lead paint) for buildings built before 1980 | Exhibit A Section XI(N)-(O) |
Whether ADOH expects a Phase I on new construction anyway, despite the text, is an open question the research did not resolve -- the same kind of open question the California guide flags for CTCAC's soft environmental hook. Given how explicit Exhibit A is everywhere else it wants something, the safer read is that new construction's environmental diligence obligation in Arizona runs through the lender and investor rather than through the QAP itself.
Federal law doesn't care which state's QAP is silent. All Appropriate Inquiries under 40 CFR Part 312 runs on its own clock regardless: ASTM E1527-21 is the governing standard (E1527-13 sunset February 13, 2024), the overall AAI window is 1 year prior to acquisition, and five components -- interviews, environmental lien searches, records review, visual inspection, and the environmental professional's signed declaration -- must be refreshed within 180 days of acquisition. A Phase I ordered early enough to satisfy an Arizona rehabilitation application's threshold review will frequently be stale for AAI purposes by the time the deal actually closes 12 or more months later.
The site can be disqualified before you file, and a local government gets 30 days to weigh in
New construction applications carry their own exclusion list, running on measured distance rather than a mapped-overlay system like California's.
| Test | Excluded or ineligible if within... |
|---|---|
| 0.5-mile buffer | Airport; chemical or hazardous materials storage/disposal; commercial junk or salvage yards; industrial or agricultural activities generating odors or pollution; active landfills; wastewater treatment facilities |
| Adjacent to, or across the street from | Adult entertainment establishment; distribution facility involving trucking; factory or similar industrial operation; jail or prison; source of excessive noise |
| Site condition | Any portion on a 100-year floodplain, unless the FEMA 8-step process, a Conditional Letter of Map Revision, or a Letter of Map Revision has been completed; or in, or with an unmitigatable effect on, a wetland |
Layered on top of the physical exclusions is a political one with a real clock. ADOH notifies the local government where the project sits and requests a letter of acknowledgment and consent under A.R.S. Section 35-728(C); the local government has 30 calendar days to respond. A missing or unfavorable letter doesn't automatically make the application ineligible -- ADOH decides whether the local government's objection is the kind Section 35-728(C) recognizes, and whether it can be mitigated, before ruling the site out. That determination carries no published timeline of its own, which makes it a real schedule risk during exactly the window a deal is supposed to be moving toward award.
Arizona is also considerably more forgiving than California on paperwork mistakes. Where CTCAC treats most threshold failures as fatal outside a narrow document-already-existed exception, ADOH's own process for erroneous, omitted, or outdated information (Section II(D)) lets it contact the Applicant, ask a third party, make the correction itself, charge a fee of up to $1,000, or -- still squarely on the table -- determine the application ineligible. The discretion cuts both ways: real relief for an honest mistake, and still ADOH's sole call.
If any structure on the site is occupied, Arizona's own state-law anchor is thin. Rehabilitation applications must include a relocation/displacement plan with a projected budget (QAP Section IV(B)(3)), but Arizona has no California-style state relocation-assistance statute. Federal obligations under the Uniform Relocation Assistance Act attach only when federal funds are in the stack, via 42 U.S.C. Section 4601 et seq. and 49 CFR Part 24 -- a state-only-funded deal next to an occupied structure has less codified protection, not less real cost.
Water is the diligence item that actually moves the needle here
Arizona's defining site-diligence risk isn't seismic or coastal, it's water. The Arizona Department of Water Resources (ADWR) administers Assured and Adequate Water Supply programs under the state's Groundwater Management Act, and getting this wrong is the one item on this list that can quietly kill a site's feasibility months after the developer thought diligence was finished.
| Program | Where it applies | What triggers it |
|---|---|---|
| Assured Water Supply | Inside Arizona's 5 Active Management Areas (portions of Maricopa, Pinal, Pima, Santa Cruz, and Yavapai counties) | A.R.S. Section 45-576: before a plat is presented for approval or lots are offered for sale/lease, the subdivider must obtain a Certificate of Assured Water Supply from ADWR's director -- unless the site will be served by a city, town, or private water company already Designated as having an assured water supply |
| Adequate Water Supply | Outside the Active Management Areas | A weaker adequacy-disclosure regime; only the first five of the seven demonstration criteria apply, and in most jurisdictions ADWR involvement isn't required before recording a plat -- though some cities, towns, and counties have separately adopted a mandatory 100-year determination as a local condition |
In practice, most infill apartment sites inside Phoenix, Tucson, and the other major Active Management Area cities never trigger an independent certificate proceeding at all -- they sit inside a service area a city or town water utility has already had Designated, and a written commitment of service from that utility satisfies the requirement outright. The deal enters the slower, independent path only when the site depends on a private well, a non-Designated private water company, or a rural Active Management Area pocket without an existing Designated provider nearby -- and that path runs on ADWR's own multi-year hydrology review, not on anything the LIHTC application calendar controls.
One mechanism worth knowing about if a site's water math is close: the owner of a Type I, Type II, or Irrigation Grandfathered Groundwater Right can permanently extinguish that right in exchange for extinguishment credits, which can be pledged to a Certificate or Designation to help satisfy the "consistency with the management goal" criterion -- A.A.C. Section R12-15-723.
Where this goes wrong
- Site control is treated as satisfied at application and then allowed to lapse before "one month after the anticipated award date" -- QAP Section IV(A)(7) sets that as the actual floor, and ADOH's curing discretion under Section II(D) is not a guarantee; "determining the application ineligible" stays on the table.
- A site-control document is assumed to satisfy Section IV(A)(7) because it shows ownership or an option, without checking that it is one of the five forms the 2026-2027 QAP now actually lists (deed, purchase agreement, purchase option, lease agreement, lease option) and that it is in writing and signed by the current owner or by both transacting parties -- a verbal understanding, a letter of intent, or an unsigned draft that would have passed muster informally under the thinner 2024-2025 standard no longer clears threshold on its own.
- No title report is ordered because the QAP never asks for one -- true at the ADOH level, but the lender, investor, and title company that have to insure the deal and record the LURA will still find a fatal Schedule B exception if nobody ever orders one, just later and with no regulatory checkpoint to have caught it earlier.
- Phase I due diligence is skipped on a new construction deal because Exhibit A's explicit Phase I mandate applies only to the rehabilitation section, and the lender's or investor's own requirement (or the federal AAI standard) surfaces the gap only after underwriting is set.
- An urban infill site is assumed to have assured water because it's inside city limits. Inside an Active Management Area, only a site served by a city, town, or private water company already Designated under A.R.S. Section 45-576 gets the shortcut; anything else needs an independent, multi-year Certificate of Assured Water Supply process discovered only after underwriting is locked.
- The A.R.S. Section 35-728(C) local-government letter is treated as a formality. A local government's silence or objection doesn't automatically kill the application, but ADOH's own determination of whether that objection is legally cognizable has no published timeline, and it lands during the exact window the deal is supposed to be moving toward award.
- An appraisal is dated to another state's habits -- more than 6 months old, or from an appraiser who isn't state-certified or USPAP-compliant -- and fails Arizona's Section VI(A)(7) freshness test outright.
- A favorable appraisal is treated as final. ADOH may, at its sole discretion, commission a second appraisal at the Applicant's expense and use the lower of the two values, so a rich number from the Applicant's own appraiser doesn't protect eligible basis the way it might elsewhere.
- The 0.5-mile incompatible-use buffer or the adjacency exclusions (adult entertainment, trucking distribution, heavy industry, jails, excessive noise) are checked at design instead of at site selection under Section IV(C)(1), after real diligence money is already spent.
- A 100-year floodplain parcel is optioned without budgeting for the FEMA 8-step process, a CLOMR, or a LOMR -- Section IV(C)(2) makes the site ineligible without one of those, and none of them are fast.
- A 4% bond deal is scheduled around a 30-day ADOH review clock that no longer exists in the 2026-2027 QAP. The Arizona Finance Authority's private activity bond volume-cap allocation, an Issuer's Delegation of Determination Letter, and the new PAB Issuance Threshold test (bond amount capped at the greater of 30% of aggregate eligible basis or the amount needed for maximum permanent debt) are all unscheduled or deal-specific dependencies that have to clear before ADOH will issue a 42(m) determination -- and no published allocation calendar was found to plan against.
- Tribal-land site control is planned on the non-tribal timeline. A 25-year lease plus a 25-year renewal option, a Tribal Council or TDHE resolution, and (where applicable) BIA and federal-public-law documentation are a materially slower path than the one-paragraph ownership/purchase-ability standard non-tribal deals use.
- A relocation budget is built assuming California-style state relocation law applies. Arizona has no equivalent state relocation-assistance statute; occupied-site obligations run through the QAP's bare relocation/displacement-plan requirement plus federal URA only when federal funds are present.
- QAP citations in a submittal are checked against whichever cycle happens to be open, not the specific text governing the applicant's own round. The 2026-2027 QAP (confirmed current as of September 2026 -- the April 1, 2026 competitive round already ran under it) changed real substance from the 2024-2025 cycle it replaced: site control now requires a written, signed, legally binding contract in one of five listed forms; the 4%/bond gate moved from Section V(B) to V(A) and added a Private Activity Bond issuance-threshold test while dropping the old 30-day ADOH decision-clock language; and the state tax credit disappeared entirely. Re-confirm every section number and requirement against the QAP actually governing the application's round before citing one in a submittal -- this guide's 2026-2027 citations rely on the Third Draft (Dec. 1, 2025), the most recent verifiable text located; ADOH's final posted version should still be spot-checked directly.
- The Arizona state tax credit (STC) is built into a 2026 or 2027 capital stack on the assumption it might still be running. It isn't: A.R.S. Sections 41-3954 and 43-1163, the statutes S.B. 1124 (2021) used to create it, each carry a delayed-repeal clause effective "from and after December 31, 2025," and the 2026-2027 QAP's Third Draft has no STC selection criteria, schedule, or scoring section left in it. Treat the STC as available only to service credits already allocated under a pre-2026 award, never as a source for a new deal.
