Riemer Massively Understated Number of Existing ADUs

In his effort to push forward his zoning text amendment on accessory dwelling units (ADUs) that would radically alter building conditions and Master Plans throughout single-family neighborhoods, Councilmember Riemer has lamented the lack of existing ADUs, claiming that only 133 exist throughout Montgomery County.

Except that figure is completely false. It greatly understates the number of existing ADUs by a factor of at least 3.5 and probably more. The information showing it’s untrue is readily available on Montgomery County websites. Indeed, memos provided to the Council in the past directly contradict the claims made by Hans in his publicly funded communications.

The county’s own website says that there are 473 existing ADUs – over three times more than advertised by Hans Riemer and other advocates of his ZTA.

A look at requests for ADU approvals under existing rules reveals 257 applications in recent years with only a small minority withdrawn or denied. The number of applications refutes Hans’s claim that virtually no one can legally build them under existing rules in Montgomery County. And this is before rules adopted just a few years ago to make it easier to build them have gone into effect and had a chance to have an impact.

In devastating follow-up testimony sent to Council President Nancy Navarro, Andy Leon Harney, explained in more detail that even these higher figures sorely underestimate the number of existing legal ADUs:

The figure often quoted that there are only 133 ADUs for a county of 1 million is simply false. In 2012, when the Council was considering ZTA 12-11, the Board of Appeals, which approved special exception accessory apartments said that between 1983 and 2012, they had approved 605 accessory apartments. Mr. Zyontz in memos to the Council at the time (10/8/12 p. 7 and 10/22/12 page 10) reported there were either 413 or 431 (probably a typo). At the same time, there were also 698 Residential Living Units—that is rent free accessory apartments approved for use by a relative, elderly parent or caregiver which are still legal and over time may well have been converted to rental units.  That would mean there were at least 1,111 ADUs plus guest houses which are no longer allowed but were grandfathered in with the passage of ZTA 12-11. The 133 number so often quoted is not accurate, and in fact there are 157 ADUs that have been approved since 2012, making the total ADUs closer to 1268, with others in the pipeline. If the Council is data driven, these facts should matter. If the Council allows itself to be persuade by an inaccurate number of “only 133 ADUs in a County of 1 million”, they are being misled.

Andy Harney is the Village Manager of Chevy Chase Section 3.

As I’ve previously explained, Hans’s legislation is deeply flawed for a number of reasons. In a post later this week, I hope to present a couple of easy amendments that would shift the focus back to the creation of smart-growth affordable housing and virtually eliminate most of the likely harms stemming from the misguided approach in the proposed ZTA.
