Washington, D.C. is considering expanding its rent regulations and initiatives could happen this year in the states of Washington and Illinois. Additionally, the states of Colorado, Illinois, and Nevada had bills introduced to their legislatures to lift statewide preemption of rent control. These measures failed to make their way out of the respective House committees due to concerted industry efforts. There was even a proposal introduced at the national level to limit rent increases to the greater of 3% or CPI increase.

Where rent control has recently become the law of the land, it's more like applying a band-aid to the affordable housing problem. California's new law has been dubbed rent control-lite because it's not true rent control in the historical sense of the term. It's actually rent stabilization, which limits how much rent can go up while a tenant is living in the unit, thereby making rent increases somewhat predictable and manageable.

California capped rent hikes at 5% per year plus annual inflation (which works out to a total of about 7%, on average) for all buildings more than 15 years old. However, in recent years, rents in California have not exceeded the cap in most areas of the state.Even in Silicon Valley, which has the highest housing costs in the U.S., market projections don't anticipate annual rent hikes of more than 7% in the foreseeable future.

With California as a model, citizen demand for rent control could indeed heighten, but that's not to say the policy will be quick to spread. In a big win for the real estate industry, more than 30 states passed laws, decades ago, barring municipalities from enacting new rent restrictions.

In fact, rent control proposals in any of these watch-list states would need to be repeal-and-replace legislation. Advocates of rent control aren't faced with an impossible battle, but it's an uphill one. But in states that don't have laws preempting rent control, local cities may move more quickly to enact new laws.

Meanwhile, something needs to be done about the affordable housing crisis. Nationwide, 37.5% of rental households spend 35% or more of their income on rent, and 23% spend 50% or more. Major markets including San Jose, Denver, San Francisco, Seattle, Boulder, Oakland and Portland have seen rents rise by more than 18% over the past four years. Of the top 20 cities with the largest rent increases, 19 are small cities.

Politicians want to look as though they are addressing the problem, and rent control is an off-the-shelf policy tool that helps some renters, at least in the short term. But there are better ways to address the problem that may not be as quick of a fix in terms of public perception, andit would benefit industry professionals to support or pitch alternatives to rent control.

In Washington, for example, a nonprofit organization composed of industry groups has formed to provide fresh ideas and a wide range of housing options, and presumably to lobby against rent control. A similar group has been formed in Illinois that is working to educate about the impact of rent control in later years.

Alternative measures include expanding voucher programs; enacting inclusionary zoning; relaxing zoning laws to encourage new construction; funding land-purchase subsidies for affordable developers; innovating public-private partnerships to allow tax abatement; pursuing innovative construction techniques, and, in places like Chicago, improving public safety in affordable areas to preserve naturally occurring affordable housing.

One way to get more affordable housing on the ground is by using new construction methods like modular housing and panelized construction, which can be built quickly and cost effectively so rents don't have to be pushed as much to get the returns that investors require. Many CRE professionals hold the opinion that the obvious and best solution is making more affordably priced units available. This would help rectify a supply-and-demand imbalance that has led to a persistent shortage of affordable housing nationwide.
