Site sourcing and screening — Connecticut

CHFA's own Housing Needs and Location indices do the geographic-targeting work up front

The Connecticut Housing Finance Authority (CHFA) is the state's sole housing credit agency, created under Chapter 134 of the Connecticut General Statutes (the CHFA Act) and designated to administer the federal Low-Income Housing Tax Credit program under Section 42(m) of the Internal Revenue Code. The current, governing document is the 2027 and 2028 Qualified Allocation Plan (QAP) -- adopted by CHFA's Board of Directors on July 23, 2026 and approved by the Governor on July 28, 2026, superseding the prior 2026 QAP. For the New Construction Classification, the QAP scores every Completed Application against a 100-point rubric spread across five categories, and a meaningful share of those points is decided before a shovel ever moves, by where the site sits.

Two of CHFA's own indices sit underneath the Housing Needs & Location category and are worth pulling at screening, not at application. The Housing Needs Index scores each of Connecticut's 169 towns on a 1-to-5 quintile using two factors: US Census data on households paying more than 50% of income on housing (HUD's extreme-cost-burden threshold), and new household formation pressure. The Location Index instead scores individual census tracts on a 1-to-5 scale (mapped to Low/Moderate/High/Very High resource categories) using school-performance and income-level data, and feeds a separate "Location Set-Aside": to be eligible, a Completed Application's score must be no lower than 85% of the highest-scoring Completed Application in that round. The QAP states CHFA's intent to direct 50% of New Construction awards to applications in High or Very High resource tracts -- so a site's Location Index category is a real go/no-go input for that half of the pool, not a minor scoring nicety.

Both indices are published by CHFA as flat town/tract lookup tables in its Housing Needs & Location Guideline for the 2027-2028 cycle -- there is no need to reverse-engineer them from raw Census data, and a screener should pull the current cycle's version directly rather than reuse an older one, since CHFA states it recalculates both indices for each new QAP cycle.

Conn. Gen. Stat. § 8-30g sets the leverage a screen has to account for before falling in love with a site

Section 8-30g of the Connecticut General Statutes -- the Affordable Housing Land Use Appeals Act -- gives an applicant for an "affordable housing development" (defined as either "assisted housing" or a "set-aside development" with at least 30% of units deed-restricted for 40-plus years) the right to appeal a commission's denial, or an approval saddled with restrictions that have "a substantial adverse impact on the viability of the affordable housing development," directly to Superior Court. What makes the appeal valuable is subsection (g): once the appeal is filed, the burden shifts to the commission to prove, on the record it compiled, that its decision is "necessary to protect substantial public interests in health, safety or other matters which the commission may legally consider," that those interests "clearly outweigh the need for affordable housing," and that they "cannot be protected by reasonable changes to the affordable housing development." If the commission cannot meet that three-part test, the statute directs the court to "wholly or partly revise, modify, remand or reverse the decision."

That leverage is not universal, however. Subsection (k) makes the entire appeals procedure unavailable in any municipality where at least 10% of all dwelling units already qualify as assisted housing, CHFA-mortgage-financed housing, deed-restricted affordable housing, or certain deed-restricted mobile-manufactured homes and accessory apartments. The Department of Housing (DOH) is required by § 8-30g(k) and § 8-37qqq to publish this list -- the "Affordable Housing Appeals List" -- annually.

One caveat worth stating plainly rather than assuming: this research checked the current, official text of § 8-30g directly against the Connecticut General Assembly's own published statutes, and no "unusually high concentration" language or defense appears anywhere in the section. The actual mechanic is binary and list-based -- a municipality is either on DOH's published exemption list or it isn't -- and the only substantive defense available to a commission in a non-exempt town is the three-part public-interest test in subsection (g), which says nothing about concentration. Anyone relying on a "concentration" framing for Connecticut specifically should treat that as unconfirmed against the current statute.

The same 10%/exemption-list determination is wired directly into CHFA's own scoring, not just into appeal rights: the "Municipalities with Less Assisted and Deed-Restricted Housing" sub-category (5 of the QAP's 100 New Construction points, and a standing Preservation-priority factor) is awarded specifically to sites in municipalities that appear on DOH's Affordable Housing Appeals List -- meaning a town's exemption from § 8-30g and its loss of these 5 QAP points are the same underlying fact, checked once. The full appeals mechanism, its burden-shifting procedure, and its use as an entitlement-pathway tool are covered in depth in Phase 3.

Environmental and hazard screening: Connecticut's data is more queryable than a lot of states, but split across three sources

CT DEEP's List of Contaminated or Potentially Contaminated Sites in Connecticut is hosted on Connecticut's open-data portal (data.ct.gov) rather than distributed as a static PDF, and DEEP states it is updated weekly -- a genuinely queryable dataset, not an annual snapshot. It compiles records from eleven separate DEEP programs (including leaking underground storage tanks, PCB sites, brownfields, and federal and state Superfund sites) into one list, but full site-file detail sits in two separate places: DEEP's REACT portal for individual remediation case records, and DEEP's Document Online Search Portal for scanned filings. Underground storage tank data is a distinct dataset again -- EPA's UST Finder aggregates roughly 45,000 historically registered Connecticut USTs, about 8,000 of which remain active, and DEEP's LUST program (for leaking tanks specifically) is reached separately by phone or email rather than through a self-service map.

CT ECO (Connecticut Environmental Conditions Online), a partnership between DEEP and the UConn Center for Land Use Education and Research, is the state's central hub for natural-resource GIS layers -- wetland and farmland soils, drainage basins, water quality classifications, and aquifer protection areas. It is not, however, the place to check flood hazard: CT ECO's own materials note that it retired its earlier flood-related map services in favor of directing users to FEMA's National Flood Hazard Layer (NFHL) directly, so a screener who goes looking for flood data on CT ECO specifically will come up short.

One state-specific layer worth flagging at screening rather than at due diligence: Connecticut's Aquifer Protection Area program regulates land use over public water-supply wells set in sand-and-gravel aquifers serving 1,000 or more people, using a two-tier map (Level B, a preliminary delineation, and Level A, the final adopted boundary). Both are published as genuine GIS/REST layers through CT DEEP's GIS Open Data hub (an Esri ArcGIS Hub site), plus a dedicated interactive Aquifer Protection Area map -- a real constraint on permitted uses in the roughly two-dozen-plus municipalities that participate in the program, and one that is actually queryable rather than locked in a PDF.

A last screening-stage flag: the Connecticut Environmental Policy Act (CEPA) requires DOH to complete a CEPA (or NEPA, where federally triggered) review before it can award any financial assistance to a project. Because most competitive 9% Connecticut deals also seek DOH soft funds, DOH's own Development Engagement Process treats the CEPA Intake Form as an optional-but-recommended exhibit at the earliest submission stage -- effectively making CEPA a screening-stage item for most real deals, not a late-cycle add-on that can wait until after site control is locked up.

Basis boost is federal-only in Connecticut -- the state's own accommodation for QCT/DDA sites works differently

CHFA's own 2026 LIHTC Program Guideline states the mechanism plainly: "If the development is within either a HUD designated QCT or DDA, the eligible basis may be increased by 30% (referred to as a Basis Boost)," citing 26 U.S.C. § 42(d)(5)(B)(ii)(I). That is the federal boost, administered automatically once HUD's own QCT/DDA designations (included in the ConApp package) confirm a site's status -- CHFA takes no separate administrative action to grant it. This research did not find a separate, CHFA-administered state basis-boost program layered on top of the federal 30% boost, the way some other states' allocating agencies operate their own add-on boost programs; none of the QAP, the LIHTC Program Guideline, or the Housing Needs & Location Guideline reviewed in this pass describes one.

What CT does instead is loosen the credit-equity underwriting ceiling for QCT/DDA sites rather than increase the basis a second time: the QAP's "Credit Equity Less than 50% of Total Uses" scoring item allows 9% Credit equity for a QCT/DDA-located development to run as high as 65% of total uses (versus 50% for every other site) without losing the associated 3 points. QCT/DDA location also separately earns 1 of the QAP's 100 New Construction points, tied to a documented community-revitalization-plan nexus. Both are underwriting/scoring accommodations layered on top of the standard federal 30% boost -- not an independent second boost to eligible basis.

Income and rent limit publication follows HUD directly, on a short local-implementation clock

CHFA does not calculate its own area median income figures; it derives Connecticut's LIHTC income and rent limits directly from HUD's Multifamily Tax Subsidy Project (MTSP) Income Limits and republishes them as its own "Income Limit Area Definitions" chart each year, subject to HUD's Hold-Harmless policy (which prevents limits from falling even when area median income drops) and the older HERA special-limits carryover for pre-2008 projects. In the one full cycle checked directly in this research pass, CHFA's 2025 chart took effect April 1, 2025 and specified that the new limits "must be put in use" by May 15, 2025 -- a roughly six-week mandatory local-implementation window tied to HUD's own release date. Both dates move every year with HUD's own publication schedule, so a screen should pull the current chart from CHFA's Income Limits and Gross Rents Look-up tool rather than reuse a prior year's PDF found through a search engine.

The rent side of the same chart matters for a screen's back-of-envelope math: maximum monthly rent is HUD's income limit (adjusted for the fewest persons per bedroom size) multiplied by 30% and divided by 12, and that maximum includes all utilities except telephone, cable, and internet -- meaning a unit's applicable utility allowance must be subtracted from the chart figure to reach the actual maximum net tenant rent (utility allowance methodology is covered in Phase 2).
