Stacking Soft Funds with LIHTC & Bonds: A California Developer’s Guide
If you’re building affordable housing financing California projects, layering soft sources—CDBG, HOME, Infill Infrastructure Grant (IIG), and Transit-Oriented Development (TOD)—with 4% LIHTC and tax-exempt bonds can close gaps without blowing up compliance. Here’s a practical playbook for assembling the stack, sequencing awards, and keeping covenants aligned.
Why Soft Funds Matter
- Fill the equity gap in 4% LIHTC/bond deals where private equity is thinner than 9% credits.
- Improve competitiveness for credit/bond allocations by demonstrating readiness, leverage, and deeper affordability.
- Finance public-facing, non-revenue items (off-sites, structured parking, streetscapes) that don’t pencil with hard debt.
Core Programs at a Glance
- CDBG (federal/local): Flexible for infrastructure and eligible housing activities; brings federal cross-cutting rules (NEPA, URA, Section 3, sometimes Davis-Bacon).
- HOME (federal/local): Deep affordability; income/rent layering; long affordability terms; federal cross-cutting rules.
- IIG (HCD): Funds infrastructure serving infill housing—utilities, streets, parks, site prep—to unlock density and speed delivery.
- TOD (state/local): Capital for projects near transit; often supports site acquisition, structured parking, and complete-streets improvements tied to ridership and VMT reduction.
Step-by-Step Stacking Strategy
Define the Deal & Eligibility Early
- Map your land use, density bonus potential, CEQA strategy, and transit metrics (distance to station, headways, walk/bike access).
- Confirm LIHTC path (4% + bonds) and model the 50% Test so tax-exempt sources “touch” sufficient eligible basis.
Build a Sources & Uses That Assigns Each Dollar a Job
- Hard costs: Pair bonds + equity for core residential costs.
- Infrastructure & off-sites: Target IIG and CDBG; keep them off the permanent loan sizing.
- Deeper affordability (30%–50% AMI units): Use HOME (and local trust funds) to underwrite long-term gap.
- Transit-adjacent costs (podium, bike rooms, first/last-mile): Point TOD here.
Sequence Applications to Maximize Readiness Points
- Run a 3-lane timeline: (A) Site control/CEQA/entitlements, (B) Soft-fund filings (IIG/TOD/HOME/CDBG), (C) CDLAC/CTCAC joint application.
- Time soft awards to land before—or contemporaneously with—CDLAC/CTCAC so your credit/bond file shows committed gap sources.
- Underwriting Alignment (“One Set of Numbers”)
- AMIs, rent limits, utility allowance method, unit mix, and set-asides must match in every exhibit.
- Tie HOME/CDBG affordability terms to the “most restrictive wins” policy across TCAC, bonds, and local covenants.
- Re-run the 50% Test after each soft-fund award to confirm bond-financed basis still clears the threshold.
Federal & State Cross-Cutting Rules—Plan, Don’t React
- Environmental: NEPA (for CDBG/HOME) and CEQA (state) need the right sequence; avoid committing federal funds before clearance.
- Labor: Davis-Bacon (federal) vs. California prevailing wage/skilled & trained—model costs for the stricter regime.
- Relocation: If acquisition/rehab or site clearing triggers URA, build timelines and budgets for notices, advisory services, and benefits.
- Procurement: Federal rules may require competitive procurement for certain scopes; coordinate with GC/CM early.
Term Sheets & Award Conditions
- HOME/CDBG: Confirm loan vs. grant structure, interest rate, default waterfall, and rent layering exhibits.
- IIG/TOD: Identify reimbursable scopes, draw conditions, and completion deadlines; avoid scopes that can’t be certified cleanly at cost cert.
- All soft sources: Calendar performance milestones, extension request windows, and reversion/recapture triggers.
Document the Covenant Crosswalk
- Create a single matrix listing: income limits, rent caps, UA method, student rule, marketing/fair housing plans, reporting cadence, affordability terms, events of default, cure periods.
- Add conflict-resolution language at closing so you aren’t trapped by incompatible terms later.
Construction Draws & the 50% Test
- Establish a draw order that allows tax-exempt bonds to finance at least 50% of aggregate basis (land + building) by placed-in-service.
- Use trustee-held accounts and requisition procedures that trace bond proceeds to eligible costs; keep soft funds supporting non-basis or later-sequence items where helpful.
Conversion & Cost Certification
- Track eligible basis line-by-line; segregate non-basis (community facilities, commercial shells) that soft funds often support.
- Prepare 8609 packages with consistent rent/income exhibits; confirm HOME/CDBG affordability riders match TCAC exhibits.
Operations & Compliance
- Publish a property-specific compliance playbook: income certifications, NAU policy, UA update calendar, fee policy, and 8823 response steps.
- Schedule federal/state reporting (HOME/CDBG annuals, CDLAC/CTCAC monitoring, continuing disclosure if publicly offered bonds).
Model Capital Stack (Illustrative)
- Tax-Exempt Bonds (construction & perm)
- 4% LIHTC Equity
- IIG (grant/loan) for utilities, streets, podium supports
- TOD funds for structured parking and station-area improvements
- HOME subordinate loan for deep affordability
- CDBG for off-site infrastructure/public improvements
- Local fee waivers/deferrals and project-based vouchers (where available)
Common Pitfalls—and How to Avoid Them
- Duplication of Benefits: Don’t fund the same scope twice; assign scopes cleanly to each source and document it.
- UA/Rent Drift: Wrong UA methodology or late updates push gross rent over limits—calendar updates and lock a method.
- NEPA/CEQA Out-of-Sequence: Committing federal funds before NEPA clearance can derail awards—sequence decisions formally.
- 50% Test Miss: Too much early soft money before bond draws—pre-plan draw sequencing with counsel and the trustee.
- Conflicting Affordability Terms: Unreconciled HOME vs. TCAC limits—resolve in the crosswalk and recorded agreements.
Closing Checklist (Soft-Fund Focus)
- Award letters with all conditions precedent satisfied
- Regulatory/affordability agreements (recorded) aligned with TCAC/bond covenants
- NEPA/CEQA determinations and labor compliance plans
- Intercreditor/subordination agreements with soft lenders
- Updated sources/uses and basis schedule confirming 50% Test
- Draw/requisition procedures (trustee, bank, and soft-fund portals)
- Compliance calendar and reporting templates
Where Counsel Adds Value
- Structuring: Puts the right costs under the right source; pairs IIG/TOD with eligible infrastructure while protecting basis.
- Sequencing: Aligns TEFRA, CDLAC/CTCAC hearings, and soft-fund timelines to hit allocation and closing windows.
- Covenant Harmony: Drafts exhibits so “one set of numbers” governs; embeds conflict-resolution clauses.
- Compliance-by-Design: Builds NAU, UA, labor, and reporting systems so operations meet the strictest standard automatically.
