MDUs Continue to Outpace Pre-Recession Totals

Construction of multiple-dwelling-unit apartments has surpassed pre-recession levels on a sustained basis. But only about half of new MDUs have fiber broadband.

  • Multifamily Broadband

New apartment buildings have always been the sweet spot for broadband network deployments, and that’s especially true today. More than 300,000 new, privately developed apartments have been started in the United States each year since 2014. This year is on track for 365,000 to 395,000 starts. That rate for large multiple-dwelling-unit properties (MDUs) far exceeds the pre-recession peak and is well over last year’s 347,000, even though construction of single-family homes has not fully recovered from the recession years. All but about 12,000 MDU units per year are in buildings with five or more units.

The Bureau of the Census does not report detailed data at the city level for housing starts but does report them for permits issued (see table on p. 26). For the first seven months of 2018, 34 percent of all housing starts in the roughly 400 metropolitan statistical areas (MSAs) were for housing units in MDU structures that contain at least five units, with an average building size of 34 units. For the 45 MSAs that reported permits for at least 1,000 MDU units, 42 percent were for units in MDUs with at least five units. Average building size was 30 units.

These new MDUs are indeed all getting broadband networks and for good reason. As researcher Michael Render reports in this issue (see p. 18), broadband is the most sought-after amenity among apartment renters and prospective condo buyers. However, at least half of new MDUs are still built with copper broadband infrastructure rather than far more robust fiber-based systems that take up less building space for equipment rooms and risers, and usually cost less to deploy in the first place.


With gigabit internet service becoming the norm and 10 gigabit on the horizon, builders should look beyond their “old, reliable” low-voltage wiring contractors for contractors who can supply the latest technologies. But many builders I talk to say they are not doing so because

  • They have copper in older buildings and believe (incorrectly) that in-building staff would have to be massively retrained for fiber.
  • They have been told that copper offers more flexibility for multiple providers to share wiring. (This is no longer true; cable companies and telcos now deploy, share and use fiber where they legally can, because fiber uses Ethernet protocols common to all broadband networks.)
  • They listen to contractors who are more used to copper and have had trouble bringing new and existing staff up to speed on fiber.
  • They worry that fiber cannot be procured quickly (which can be true for citywide builds but generally is not an issue for MDU builds).
  • They believe wireless will handle all demand. (Wireless has limitations on how many users can share at a time, and wireless requires fiber connections to the internet.)
  • They have not thought through the need for other networks in a building to handle fire alarms, video security, energy management and so forth.
  • They are not sure about future tenant demand. But the Census Bureau reports that the percentage of people on regular payrolls (that is, getting a W-2 tax form at the end of each year) who work entirely at home grew from 3.3 percent of the workforce in 2000 to 5 percent in 2016 to 5.2 percent in 2017. In raw numbers, that is an increase from 4 million to 8 million people. The Census Bureau also counts more than 10 percent of the workforce in the “gig economy” either part time or full time.

It is unclear from census data how many households or occupied dwelling units have residents working from home. Do both members of a household tend to work at home? Only one? Is the pattern different for couples than for young workers sharing living space to split the rent? Is the gig (job, not bandwidth) part time or full time? Is the home business a small added income or a major part of family income? Render reports (in this issue) that 58 percent of condo owners under 35 sometimes work from home and that 19 percent have home-based businesses. The best advice is for MDU owners and managers to survey the needs of their own tenants and prospective tenants. What is absolutely clear is that home-based workers need fast, reliable, symmetrical broadband.


Large builders and deployers are well aware that local markets do not always – or even usually – exactly mirror national and regional trends. They are also aware that local radio, TV and newspapers tend to report only aggregate national numbers for all housing starts. These days, the aggregate number is about 1.2 million housing starts a year. Two of every three new units are single-family homes, many of which replace old housing that has fallen into disrepair.

The data are collected by private contractors hired by the Census Bureau. But there are 40,000 communities in the United States, and not all require construction permits. So in its national reports, the Census Bureau inflates the numbers it collects by 3.3 percent.

In many states, large developments are built outside city or town borders in unincorporated areas and then folded into those communities once construction is finished. Thus, although the number of units completed nationally tends to be about 7 percent less than the number started, the number of dwelling units completed can be larger for a given location. That has not been the case for the past few years, however. Overall, MDU completions have tended to be successful at a higher rate in the past few years – closer to a 3 or 4 percent drop from starts.

For clarity, the charts do not include the small number of housing units in buildings with two, three or four apartments – 10,000 to 12,000 units a year for the past decade. The annual rate of five-plus-unit MDUs started in 2017 ranged from 277,000 to 416,000, as stated in the monthly reports. Exceptional weather – good or bad – tends to account for much of this variation. The year ended up with 343,000, revised down from 352,000. The average annual rate of MDU starts this year, 395,000 through July, is up 13 percent from 2017. As noted earlier, the final number could be as low as 365,000 – still a record.

There are also regional variations, and those are reported about a year late by the Census Bureau. The Bureau does not break out number of units in very small MDUs – those of four units or fewer – in the regional data, but it does in the MSA-level data. The second chart shows how much of the MDU market is driven by regional housing patterns, however.

MDUs, as one might expect, tend to be small in rural areas, but in rural population centers of fewer than 50,000 people, garden and dwelling-above-store apartments are not uncommon and are easy to provide broadband for, as long as the community itself is well connected to the outside world. MDUs that are nonresidential – hotels, hospitals and dormitories – are more common in the South, as are retirement communities in rural areas, even though rural populations have declined more in the South than elsewhere since 2010.

Indeed, in the aggregate, rural areas have been losing population since 2010. The loss – more than 1 percent of the 42 million living in rural counties that year – produced a surplus of more than 200,000 dwelling units in those counties.

Small regional and local broadband carriers move quickly to take advantage of opportunities presented by new residential construction. Local carriers do not usually need the census to tell them what is going on in their own communities. To take advantage of local opportunities, national property owners and managers need to strengthen connections to local carriers.

Privately Owned Housing Starts 2004-2018
Chart 1: Red line shows construction of MDU buildings with at least five units. Most new units are in buildings of 20 units or more; the average building size this year in MSAs is 34. In this chart, the roughly 12,000 annual construction totals for MDUs of two, three or four units is omitted to keep 2018 data compatible with earlier years.
MDU Housing Starts by Region 2008-2017
Chart 2: There are significant regional variations in annual MDU construction. Most MDU growth has been in the South and West since the recession started in 2008. In this chart, MDUs of all sizes are aggregated; the Census Bureau does not fully reported MDU data by size in this data series.

Vendors now offer new products to make MDU fiber deployments ever-cheaper to implement. The fiber is thinner and more flexible than in years past. Connections rarely require fusion splicing, so deployments are faster and require less skilled labor. Fiber can be pulled inside with no splice at all – workers can simply strip off weather shielding.

Hubs are smaller as well, making fiber easier to deploy and maintain with standardized trays and simple but effective gaskets that allow easier maintenance.

Older buildings benefit, too, with techniques that combine existing copper with wireless,, DOCSIS 3.1 and true, all-fiber, passive optical networks that terminate at a property line or basement.


Even experienced property developers and broadband suppliers fall into the new economy’s financial traps when they justify broadband builds. One glaring example: New MDU construction is overwhelmingly for rental units. The percentage of owner-occupied dwelling units overall has fallen from its peak – nearly 70 percent – to 64 percent today. Young, first-time buyers and those who lost their homes to foreclosure or short sales in the recession have great difficulty finding mortgage lenders. Rental costs are rising relative to income, driven by the resulting demand for rental units. This has increased the number of unrelated people who share apartments and ostensibly single-family housing units.

Deployers are well tuned to credit issues. Thus, there has been an increase in the number of households offered bulk services, in which broadband costs are treated as part of the rent rather than as a separate fee. This saves residents money, cuts deployer operating costs, and puts building owners on the hook for the fees. But it also reduces tenant broadband choice and induces many to take only the bulk package with no extras. That in turn, requires buildings to spend on good wireless infrastructure while tenants look to over-the-top services and even cellular for other content.

Tenant churn creates a hidden cost for deployers, however. Unrelated people renting apartments together are particularly unstable tenant groups even when each individual tenant has a good income. As tenants move in and out of apartments and swap partners, the actual monthly broadband revenue earned by deployers tends to stay close to the promotional price.

No longer can deployers depend on higher revenues from tenants who have completed promotional terms. What’s the penalty? From 12 to 30 percent of “full price” revenue – and the 12 percent is for short promo periods of three to six months. Even a 12 percent hit can destroy all profit potential.

Expect the bias toward rentals to continue for several more years. The Federal Reserve Bank has started to reduce the money supply by reducing its balance sheet. When the recession started in 2008, the FRB had about $800 billion in assets. That grew fivefold to around $4 trillion as the FRB bought up lower-quality assets (mainly bonds) – a process called “quantitative easing.” The money it spent went into circulation, but the assets it carried on its books could also be borrowed against by other banks.

Although the supply of money went up, it tended to move around less until the economy recovered. If that had not happened, the extra money in the system would have caused a great deal of inflation. Instead, it made money easy to borrow, at least by businesses if not by individuals. Money has been available to home builders and network deployers at interest rates in the 3 to 6 percent range.

Now the FRB is more worried about inflation. So as it reduces its balance sheet, and thus the money supply, it has only recently begun to raise interest rates. That, in turn, puts smaller local banks in a quandary. If they can’t raise interest rates beyond what the FRB posts, they will tend to avoid lending long-term to individuals or to capital-intensive businesses. And no businesses are more dependent on 15- to 20-year financing than network deployers.

The scarcity of long-term capital has enticed MDU developers – who typically finance with interest-only loans that are rolled over every five years – to finance network builds themselves. Will that continue? What happens to the money supply as the federal deficit balloons to 20 percent of the federal budget this year? Does the increased money supply and moderate interest rate make up for the federal government’s beginning to crowd out local borrowers? There are models to predict the answers to these questions. But for the past 18 months, I have been attending FRB meetings on these subjects in Boston and New York – meetings that usually have Nobel Prize economists at the table. The verdict: The models have never been tested with money swings of this size. This is not comforting.


Immigration policy is in flux, and net immigration is supposedly falling. There are more deportations and fewer immigrants entering the United States. But the number of children in custody, the firmest data we have, has continued to rise through 2018, while the number of refugees admitted permanently has fallen to just over 20,000 so far this year. The White House has announced an annual cap of 30,000, down substantially from the modern peak year of 108,000.

Before the policy change, the Census Bureau estimated that all net population growth in the United States after 2020 would be from net immigration. Changing that outlook would have major implications for housing construction of all kinds.

But the impact would probably be greatest for residential MDU construction. There would be fewer construction jobs, fewer opportunities for broadband deployers, and a smaller economy overall.
