NAHB's Multifamily Production Index printed 41 in the third quarter of 2026, down five points year over year, and the Multifamily Occupancy Index printed 69, also down five, the National Association of Home Builders reported November 5, 2026. Every MPI component is below 50. Sixty-six percent of developers said the market is about the same as three months ago.
That is the split operators should underwrite: starts look poor, occupied buildings still look decent, and nobody thinks the tape just turned. Garden product, which carries half the production index, dropped through break-even. High-rise and condos were already there.
What Do MPI 41 and MOI 69 Mean on NAHB's Scale?
Both indexes run 0 to 100. Above 50 means more respondents call conditions good than poor. Below 50 means the reverse. MPI is a weighted average of four start conditions: garden/low-rise (0.50), mid/high-rise (0.33), subsidized (0.12), and built-for-sale (0.05). MOI weights occupancy of existing rentals: garden (0.60), mid/high-rise (0.25), subsidized (0.15).
| Component | Q3 2026 | YoY change |
|---|---|---|
| MPI (overall) | 41 | -5 |
| Garden / low-rise MPI | 46 | -5 |
| Mid / high-rise MPI | 33 | -4 |
| Subsidized MPI | 49 | -6 |
| Built-for-sale MPI | 31 | -4 |
| MOI (overall) | 69 | -5 |
| Garden MOI | 70 | -6 |
| Mid / high-rise MOI | 59 | -7 |
| Subsidized MOI | 83 | +2 |
NAHB redesigned the survey in 2023 and still lacks enough history to seasonally adjust. The press release is explicit: compare year over year, not quarter to quarter. The published table still shows MPI sliding 44 / 43 / 41 across 2026's first three quarters, and MOI snapping back to 69 after 74 in Q2, matching Q1's low in the series that starts in Q3 2023.
Why Did Developer Sentiment Soften?
Kip Lewis, director of construction management at OCCH in Columbus, Ohio, and chairman of NAHB's Multifamily Council, named the three constraints every construction lender already has in the file:
"Developer sentiment about new multifamily production has definitely softened, due to challenges such as rising interest rates, construction costs that are high relative to rents, and problems getting projects approved and connected to roads and utilities. As a result, many projects are taking longer to complete."
- Kip Lewis, Chairman, NAHB Multifamily Council
That is a duration problem as much as a starts problem. A deal that still pencils can miss its rate lock because the city will not sign the utility letter. Mid/high-rise at 33 is the vertical version of that delay: more steel, more agency touchpoints, worse sentiment.
Garden's drop to 46 is the bigger index event because of the 50% weight. When the workhorse product crosses below 50, the headline MPI cannot hide in condos or tax-credit extras. Subsidized at 49 is the closest to break-even and still negative. For-sale at 31 says the condo bid is not a release valve.
What Is Robert Dietz Forecasting for 2027 Starts?
NAHB chief economist Robert Dietz connected the MPI print to the association's forward calendar:
"It is not surprising that the MPI is down year-over-year given supply-side headwinds such as high interest rates and a rising rental vacancy rate. Due to the headwinds still facing the industry, NAHB's 2027 forecast shows a decline for multifamily starts. And although the administration's regulatory reform efforts are helping to ease some cost pressures, the multifamily sector would still benefit from an expedited permit process and lower rates on development and construction loans."
- Robert Dietz, Chief Economist, NAHB
Dietz wants two things: faster permits and cheaper construction debt. California just funded affordable apartments through Proposition 1's $7.2 billion multifamily allocation and rejected CEQA-streamlining Proposition 45. That is Dietz's sentence in ballot form: money without an expedited process.
RealPage's October update already showed same-store effective rents down 0.7% month over month, occupancy at 95%, and 304,800 units absorbed versus about 318,000 completed in the year through Q3. NAHB's "rising rental vacancy" line and RealPage's first down month of 2026 are the same tape from two desks.
Do Developers Think Conditions Changed in the Last 90 Days?
NAHB asks a separate three-month comparison because the indexes are not seasonally adjusted. In Q3 2026:
- Better: 6%
- About the same: 66%
- Worse: 28%
A year earlier those shares were 10% / 68% / 22%. The majority still sees a sideways market. The bearish tail got fatter. Only 6% see improvement, which is why "stabilizing" should not be confused with "turning up."
The sample is thin. NAHB mailed 1,290 multifamily developers and got 55 responses. Treat the print as a sentiment flag, not a census. RealtyWire noted NMHC's recent construction survey found 29% of apartment developers started fewer projects last quarter, which points the same direction even if the panels differ.
Which Product Types Still Have Occupancy Cushion?
MOI at 69 is not a vacancy crisis. It is a weaker good. Subsidized occupancy at 83 is the standout: tax-credit and other income-restricted stock is still filling, and that component rose two points year over year. Garden occupancy at 70 remains comfortably above 50 even as garden production fell below 50. That is the classic late-supply sequence: existing gardens lease, new gardens get harder to start.
Mid/high-rise occupancy at 59 is the softest rental bucket and still net-positive. Pair that with MPI 33 and the high-rise story is: buildings in place are okay, new towers are not. Trademark and Morgan still broke ground on 362 Oak Lawn units in Dallas in November, which is what a site-specific infill bet looks like when the national production index is 41. National sentiment is not a local prohibition.
The Numbers Worth Writing Down
- MPI: 41 (-5 YoY)
- MOI: 69 (-5 YoY)
- Garden MPI / MOI: 46 / 70
- Mid/high-rise MPI / MOI: 33 / 59
- Subsidized MPI / MOI: 49 / 83
- For-sale MPI: 31
- Same vs. 3 months ago: 66% (28% worse, 6% better)
- Responses: 55 of 1,290 surveyed
Occupied Stock Is Fine; The Pipeline Is the Tell
MPI 41 is a starts call. MOI 69 is an operations call. Mixing them into one "multifamily is weak" headline is how people mis-time acquisitions. Existing gardens and subsidized assets still clear NAHB's good-versus-poor test. New mid-rise, high-rise, and condo product does not.
Dietz already told you the 2027 starts line is down. The 66% "same as three months ago" majority is not a rebound thesis. It is a grind. Price occupied, supply-constrained submarkets. Do not underwrite a 2027 delivery boom off this survey.
