Compliance monitoring through the 55-year tail — California

Four clocks, and the one date worth storing

A LIHTC deal runs four overlapping clocks, and confusing them is the most common source of error in this phase.

Years 11 through 15 are where naive models break. Credits stop flowing at year 10, but recapture exposure and the full federal certification burden run through year 15, and so do asset management fees, reserve draws and the cash flow waterfall.

The 55 years is vintage-dependent, which matters whenever you are underwriting an acquisition of an existing property rather than a new allocation.

Terminology drifts between documents — "55-year regulatory period" and "15-year compliance period plus a 40-year extended use period" describe the same obligation. Store one canonical field, the regulatory agreement expiration date, and derive the rest from it.

The annual machine: certification, monitoring and the 8823

The owner's Annual Owner Certification package is four reports — the AOC itself, the Project Ownership Profile, the Annual Operating Expense report, and the Lender Report. Underneath it, federal law requires an annual certification under penalty of perjury covering the twelve items in 26 CFR Section 1.42-5(c)(1) for each year of the 15-year compliance period.

Sampling is where the California overlay bites.

An owner who fixed it in time still carries that 8823 into the Year-15 file.

Two quiet traps. "100% affordable means no recertifications" is wrong: the move-in certification and a first annual recertification are still required, income verifications may stop after that, but full-time student status must be checked for the entire tenancy and throughout the initial compliance period. And the year-1 resident file must be retained six years beyond the due date of the return for the last year of the compliance period — roughly 21 years of custody for a single year's paperwork.

Recapture, and what enforces the covenant afterward

The accelerated portion (Section 42(j)(3)) is the excess of the credit actually allowed for prior years over the credit that would have been allowable had the total been spread ratably over 15 years instead of 10. The credit is earned over 10 years but vests over 15. That is the origin of the widely quoted "one-third" rule of thumb — it is a derivation from the statute, not a statutory figure. A calculator has to run the two schedules and subtract, then layer interest year by year, not apply a fraction.

Recapture stops at year 15. The extended use agreement remains enforceable as a recorded restrictive covenant under Section 42(h)(6)(B)(vi), and California enforces it with negative points, fines and liens instead.

California's money layer: fees, fines and the AB 846 rent cap

The fee covers monitoring throughout the extended use period and is generally payable before issuance of the 8609 / FTB 3521A. It is a capitalized 55 years of monitoring rather than an annual expense — which is exactly why it goes missing from early models.

The AB 846 rent cap is the most consequential recent change for feasibility math.

The teeth are at exit. Section 10338(a)(4) bars the Executive Director from approving a transfer if, in any of the five calendar years prior to the transfer — but not earlier than April 3, 2024 — the owner raised rent above the Section 10336(a) limits. A rent-cap violation in year 11 can block the year-15 sale.

Two things here are genuinely unsettled and worth saying out loud. The cap makes the achievable rent path-dependent — the ceiling is the lesser of the AMI-derived limit, market, and prior rent grown by the capped percentage — which in principle means carrying a per-household rent history rather than a per-unit AMI lookup. But the source material does not resolve whether the cap resets on household turnover, and that answer determines how large the problem actually is: if a new household resets to the AMI-derived limit, the drag is bounded by tenure. Separately, the claim that the effect compounds significantly over a 55-year hold is presented in the research as an inference from the mechanics, not a published or backtested figure.

Year 15: a smaller decision set in California than elsewhere

The general partner's options are finite: buy out the LP interest; exercise a right of first refusal; resyndicate with new 4% or 9% credits; sell to a third party as affordable; or hold to year 55. Each has its own approval path and its own document dependency.

One option available elsewhere is not available here.

The feasibility consequence is blunt. A California model must not carry a year-15 unrestriction scenario, and must not value a property on an assumed 15-year restriction. A residual premised on market-rate conversion at year 15 is not an aggressive assumption, it is an impossible one. This is a per-state rule, not a global constant — qualified contract exits do occur in other states — and it is the error out-of-state capital evaluating California deals is most likely to make.

The right of first refusal is the other pillar.

Do not model ROFR exercise as automatic, and be candid that the underlying question is contested. The statute still reads "right of 1st refusal," and the last substantive amendment to Section 42(i)(7)(A) listed in the current U.S. Code text is Pub. L. 101–508 Section 11407(b)(1) (1990); the research could not verify enactment of any proposal converting it into a purchase option. A common-law right of first refusal generally requires a bona fide third-party offer to trigger, and aggregator LPs contest whether a GP may manufacture that trigger. Reported outcomes are mixed and fact-specific.

Exit tax is the year-15 surprise that reprices everything else. When the LP's capital account has gone negative, disposition triggers gain. The commonly used approximation — negative capital account times the marginal rate, divided by one minus the marginal rate — is industry practice, not authority, and depends entirely on the partnership's tax history. It routinely converts an expected zero-dollar buyout into a seven-figure ask.

Transfer Events, the Qualified CNA and resyndication mechanics

A "Transfer Event" (Section 10302(qqq)) is broader than a sale: transfer of project ownership, sale or assignment of a partnership interest in the owner, or refinancing of secured debt. It applies only where at least 50% of units are Tax Credit Units, and the carve-outs matter.

A Transfer Event triggers a Qualified CNA and a Capital Needs Covenant (Section 10338(b)).

Resyndication adds conditions that are cheap to plan for and expensive to discover late.

Refinancing deserves its own warning.

Lenders who assume they can obtain a subordinated regulatory agreement are wrong.

What this phase reaches backward into underwriting

Almost everything binding here was elected three to five years earlier, when it was cheap to change.

One more that nobody models: the year-1 applicable fraction is locked forever. Qualified basis and applicable fraction are recorded at the end of the first credit year, so an unqualified household in a unit in year 1 permanently reduces the fraction for all 15 years. Lease-up risk is a compliance-period fact, not just a stabilization one.

Finally, the framing. With a positive-cash-flow-for-15-years requirement (Section 10327(f)) and no cap-rate exit for 55 years, an IRR-and-exit-cap model produces a number nobody in this industry uses. What the tail actually determines is whether deferred developer fee gets repaid, and what the GP owes if it does not.
