On ADUs:
The Northwest Current has a piece by Brady Holt regarding accessory dwelling units (page RE14). Quotes one local developer as saying it costs $200K to $400K to build a basement unit and a realtor as estimating that a legal basement unit adds $200K to the appraised value of a home.
On Parking:
Emily Badger's "Why the Poor Need Better Access to Cars" (on Wonkblog) and/or Driving to Opportunity, the Urban Institute study it summarizes.
"The Cost of a Parking Spot" from Urban Turf looks at current asking prices for both sales and monthly rentals of parking spaces in a variety of DC neighborhoods. The article says that sale prices appear to have increased about $5,000 to $10,000 since their last survey in 2011.
Updates to the chart on public input:
I've added two entries -- (1) Substandard lots (those that fail to meet the minimum SF or width requirements for the zone) now require a variance. If the ZRR were adopted, development of such lots would be matter of right. (2) Prohibited uses, which also require a variance under the current code, would require approval of the Zoning Administrator (ZA) under the ZRR. Note that the ZA does not provide notice or hold hearings prior to approving requests made by the property-owner. While any property owner, developer, real estate lawyer, or architect may request a determination letter from the ZA, typically the ZA does not offer any justification for a decision that a project complies with zoning requirements. As a result, it's virtually impossible to evaluate consistency across cases.Here's an example (from Subtitle D, page D-74) of one of the regs that effects change #2:
1611 USES NOT IDENTIFIED IN R ZONES
1611.1 Any use or Use Group not included in tables or otherwise permitted by conditions, special exception or as an accessory or home occupation of this chapter shall be deemed not permitted unless determined by the Zoning Administration to be compatible with like permitted uses and consistent with the general use impacts of permitted uses.
Translation: Anything not mentioned is prohibited -- unless the ZA allows it.
What are the odds that, in 980 pages of text, such a passage would leap out at a casual reader? What are the odds that all five of the Zoning Commissioners noticed it and know what it means?
And change #1 (matter-of-right development of substandard lots) is even more elusive.
These are the kind of significant changes that are flying under the radar in the Zoning Regulations Review process.
