Arlington planning commission adopts 26‑item UDC annual update, including short‑term rental caps and code clarifications

The Arlington Planning and Zoning Commission on April 16 voted unanimously to adopt the city’s UDC 2024 annual update, a package of 26 amendments to the Unified Development Code designed to clarify language, correct errors and make targeted substantive changes.

Richard Gertson, assistant director for Planning and Development Services, told commissioners the package includes five clarifications, nine corrections, two new or modified definitions and nine substantive changes covering a range of topics from permitted uses in the flex hybrid district to short‑term rental rules. “We thought we had eliminated all those special nonconforming status that we gave it… we found two more that we had accidentally skipped over,” Gertson said, describing archival cleanups and substantive edits.

Why it matters: the amendments revise allowed uses and definitions, set clearer standards for accessory structures and overheight setbacks, refine landscaping and drainage attestation requirements, and add a cap on short‑term rentals in multifamily projects within and outside the STR zone.

Commissioners questioned several provisions during discussion. Commissioner Sumter pressed staff on the alternate equivalent compliance (AEC) process and the 15% cap for dimensional adjustments, saying it “is somewhat limited” on constrained lots and proposing a 50% cap to increase developable area. Sumter said, “If you maybe thought of a 50% reduction … I think that would somewhat and could potentially double the developable area.” Staff said the AEC remains discretionary and is intended to provide case‑by‑case leeway rather than automatic waivers.

The update also addresses short‑term rentals (STRs): within the city’s STR zone the number of units in a multifamily complex that can be used as STRs would be capped at 25 units or 15% of total dwelling units, whichever is greater; outside the STR zone the maximum is 25 units or 15% of total units, whichever is less. Staff said the distinction aims to allow higher density of STRs within the entertainment district while limiting saturation elsewhere.

The commission moved and approved adoption of the full package by an 8‑0 vote. The amendments will proceed according to the city’s adoption procedures; specific effective dates were not stated in the hearing record.

Implementation notes: staff indicated several changes align the UDC with the City’s design criteria manual and state chapter references, require pre‑application meetings for certain zoning board submissions, and consolidate the historic‑preservation certificate and demolition/relocation permit hearing processes into a single consolidated hearing to increase efficiency.

What’s next: the UDC amendments will be incorporated into the code following standard administrative adoption steps. The commission did not record any separate motions to send items individually to the council during this meeting.
