Other federal grant funds (general)	Default no Statute names only four specific programs as countable (Tribal Transportation Program, Federal Lands Transportation Program, TIFIA, RRIF) — TIFIA and RRIF are tracked as their own rows in this table; general other-federal beyond those four is default no.

Read directly (2026-09-21) — previously sourced only to FHWA's federal-share fact sheet, which this supersedes as primary citation.

CDBG	Source-side authority BUILD's own statute (49 USC 6702) lists only TTP/FLTP/TIFIA/RRIF as countable other-federal sources — CDBG's source-side authority doesn't clearly reach BUILD specifically. 24 CFR 570.201(g) → Verified Sep 20, 2026	Source-side authority DOT cites this reg as source-side authority for using CDBG on other federal cost share. Conditions not verified — the underlying statute/regulation wasn't read directly. 24 CFR 570.201(g) → Verified Sep 20, 2026	Confirmed (statute) Not named specifically — covered by the general other-federal-assistance provision, same 80%/low-density-state cap as any other federal source. Read directly (2026-09-21). CDBG is not named anywhere in 23 USC 117 — it simply falls under the general "Federal assistance other than a grant under this section" language, same as any other federal source. Previously sourced only to FHWA's fact sheet; this replaces it. 23 USC 117(j)(2) → Verified Sep 21, 2026	Confirmed (statute) Counts as other federal within the 80% cap.

Title 23 formula funds	Unconfirmed Read directly (2026-09-21): subsection (e)(3), "Treatment of other federal funds," names exactly four countable programs — Tribal Transportation Program (23 USC 202), Federal Lands Transportation Program (23 USC 203), TIFIA (23 USC 601(a)), and RRIF (chapter 224). No Title 23 formula program is on that list. Verified Sep 21, 2026	Unconfirmed 23 USC 130(h) lets the Section 130 crossing set-aside cover a state-law-required local match on Section 130 projects THEMSELVES — that's intra-Title-23 use, not authority to use Section 130/STBG/HSIP funds as match on a different federal program like this one. Checked (2026-09-21); nothing found confirming or denying cross-program use.

Regional commission funds	Source-side authority Whichever regional commission covers the project area (Appalachian Regional Commission, Delta Regional Authority, or Northern Border Regional Commission) may have its own statutory authority to pay part of the non-federal share on another federal grant program — see notes for the specific citation per commission. Researched and verified directly (2026-09-21). Three separate regional-commission statutes each grant source-side authority, none naming any rail/port program specifically: ARC — 40 USC 14321(a)(4), "Notwithstanding any law limiting the federal share in any other federal or federal grant program, amounts appropriated to carry out this section may be used to increase that federal share, as the Commission decides is appropriate." DRA — 7 USC 2009aa-3, may raise a project's federal share up to 90% using DRA funds, conditioned on the administering federal agency certifying the project meets that program's own requirements. NBRC (and Subtitle V regional commissions generally) — 40 USC 15507 ("available for the payment of the non-Federal share for any project carried out under another Federal grant program") plus 40 USC 15506(b).

Default no

Default no unless the source program's own statute allows it. The NOFO's budget tables track "Other Federal Cost Share" as a separate line, not as match.

Confirmed (statute)

Up to 80% total federal assistance for most states; a state with population density ≤80 persons/sq mi (2010 census) instead follows 23 USC 120(b)'s cap.

Read directly (2026-09-21) — previously sourced only to FHWA's federal-share fact sheet, which this supersedes as primary citation. Statute text: "Federal assistance other than a grant under this section may be used to satisfy the non-Federal share of the cost of a project for which such a grant is made" (subject to the caps above).

CDBG

Source-side authority

BUILD's own statute (49 USC 6702) lists only TTP/FLTP/TIFIA/RRIF as countable other-federal sources — CDBG's source-side authority doesn't clearly reach BUILD specifically.

Source-side authority

DOT cites this reg as source-side authority for using CDBG on other federal cost share. Conditions not verified — the underlying statute/regulation wasn't read directly.

24 CFR 570.201(g) →

Verified Sep 20, 2026

Confirmed (statute)

Not named specifically — covered by the general other-federal-assistance provision, same 80%/low-density-state cap as any other federal source.

Read directly (2026-09-21). CDBG is not named anywhere in 23 USC 117 — it simply falls under the general "Federal assistance other than a grant under this section" language, same as any other federal source. Previously sourced only to FHWA's fact sheet; this replaces it.

Title 23 formula funds

Unconfirmed

Read directly (2026-09-21): subsection (e)(3), "Treatment of other federal funds," names exactly four countable programs — Tribal Transportation Program (23 USC 202), Federal Lands Transportation Program (23 USC 203), TIFIA (23 USC 601(a)), and RRIF (chapter 224). No Title 23 formula program is on that list.

Unconfirmed

23 USC 130(h) lets the Section 130 crossing set-aside cover a state-law-required local match on Section 130 projects THEMSELVES — that's intra-Title-23 use, not authority to use Section 130/STBG/HSIP funds as match on a different federal program like this one. Checked (2026-09-21); nothing found confirming or denying cross-program use.

Regional commission funds

Source-side authority

Whichever regional commission covers the project area (Appalachian Regional Commission, Delta Regional Authority, or Northern Border Regional Commission) may have its own statutory authority to pay part of the non-federal share on another federal grant program — see notes for the specific citation per commission.

Researched and verified directly (2026-09-21). Three separate regional-commission statutes each grant source-side authority, none naming any rail/port program specifically: ARC — 40 USC 14321(a)(4), "Notwithstanding any law limiting the federal share in any other federal or federal grant program, amounts appropriated to carry out this section may be used to increase that federal share, as the Commission decides is appropriate." DRA — 7 USC 2009aa-3, may raise a project's federal share up to 90% using DRA funds, conditioned on the administering federal agency certifying the project meets that program's own requirements. NBRC (and Subtitle V regional commissions generally) — 40 USC 15507 ("available for the payment of the non-Federal share for any project carried out under another Federal grant program") plus 40 USC 15506(b). Same caveat as the CDBG rows: this is generic source-side authority — none of these three statutes confirms this program's own NOFO or statute actually accepts it.
