Montgomery County committee narrows workforce-housing zoning changes, forwards ZTA 25‑02 to full council 2–1

A Montgomery County Council committee voted 2–1 to forward a zoning text amendment aimed at increasing workforce‑housing opportunities along designated corridors, moving the measure to the full council with a committee recommendation after several technical and policy compromises.

The Planning, Housing and Parks Committee spent most of the work session debating which parcels should be eligible under ZTA 25‑02 and how subdivision and parking rules should interact with the new standards. Chair Friesen opened the session and directed staff to walk through diagrams and maps requested at an earlier meeting.

Why it matters: The ZTA would change where duplexes, triplexes and small multiunit projects can be built along County corridors and ties those approvals to workforce‑housing requirements. Staff told the committee that the initial parcel universe was about 2,470 eligible lots; removing controlled major highways eliminates 27 parcels and including corner lots would have added roughly 475 parcels — proposed changes that prompted close scrutiny.

Planning staff demonstrated lot‑consolidation exercises across R60, R90 and R200 zones and found that development controls (lot coverage, setbacks, on‑site parking, and stormwater requirements) limit practical density. "Most developments, even with lot consolidation, actually don't achieve the maximum permitted FAR of 1.25," planner Atul Sharma said, noting simulations typically reached FARs of 0.6–0.9 and that "an underground parking space can cost anywhere between $50,000 to $75,000 per space to build." Those constraints undercut some public fears about large complexes being built on small lots.

The package of committee decisions and clarifications - Flag and through lots: The committee agreed 3–0 to an amendment that makes existing flag lots and through lots ineligible under the ZTA and asked staff to draft a companion subdivision regulation amendment (SRA) to prohibit creation of future through or flag lots to take advantage of the ZTA. Staff said it will identify which of the originally mapped parcels are flag lots and update counts accordingly. - Corner lots and service roads: Members debated whether corner lots should be eligible (staff warned adding corner lots would add ~475 parcels). Service roads were discussed at length; staff counted 2,470 eligible parcels initially and identified 630 parcels on service roads (about 25% of the total). The committee elected to retain the current treatment of service roads rather than adopt substantial expansions or reductions. - Parking for triplexes and small multiunit buildings: Planning presentations and diagrams showed that R60 lots are constrained for 6‑space triplex parking. The committee adopted staff's compromise that reductions in required parking for 3+ unit projects in R60/R40 (within a half mile of transit) be subject to Planning Board approval rather than an automatic waiver. - Affordability controls and short‑term rentals: Members debated whether to extend resale control periods, ban short‑term rentals for workforce units, or require one of two units in a duplex to be workforce‑restricted. Staff and the committee noted that changes to the underlying workforce‑housing program (control period and administrative processes) are typically handled by DHCA or a separate bill; there was no committee majority to impose a 40‑year resale control or to raise the workforce requirement for duplexes to 50%.

On procedure, Chair Friesen emphasized the distinction between zoning text and subdivision law: consolidation and lot‑line adjustments are governed by the subdivision code and any measures to limit through‑lot creation will require an SRA to take effect. "Consolidations happen during subdivision," Friesen said, explaining why a companion SRA was appropriate.

The committee voted to forward ZTA 25‑02 to full council with a 2–1 recommendation and requested staff continue refining maps, flag‑lot identification, and the proposed SRA. The full council will now decide whether to adopt the committee's amendments.

What's next: Staff will update the online eligibility map (and may prepare an address/parcel list), draft the SRA, and provide follow‑up materials prior to the full council calendar. The committee indicated continued community engagement would follow as the proposal moves forward.
