North Potomac is an unincorporated CDP in Montgomery County; governed by Montgomery County Code Chapter 59 (eff. 2014-10-30) administered by M-NCPPC. No municipal zoning. The CRN/CRT/CR FAR-suffix convention: first number=total FAR, C=commercial FAR, R=residential FAR, H=height. Legacy RT zones (RT-8.0, RT-10.0) and PD zones are retained from pre-2014 ordinance per Article 59-8; they cannot be newly applied after October 30, 2014.

Worth knowing
  • North Potomac is an unincorporated CDP in Montgomery County — no municipal zoning authority. All zoning is under Montgomery County Code Chapter 59 (eff. 2014-10-30) administered by M-NCPPC (Maryland-National Capital Park and Planning Commission).
  • CRN/CRT/CR zone designations encode total FAR, commercial FAR (C), residential FAR (R), and max height (H) in a single string per §4.5.2.A.2 — e.g. CRN-0.25 C-0.25 R-0.0 H-35 means total FAR 0.25, max commercial FAR 0.25, no residential FAR, max height 35ft. Each map designation is a unique zone.
  • RT-8.0, RT-10.0, PD-2, PD-3 are legacy zones retained from the pre-2014 ordinance under Article 59-8 — these cannot be newly applied after October 30, 2014, but remain in force on previously-zoned properties. These are mapped within North Potomac according to the GIS query.

State preemptions

MD HB 1466 2025 — Small Houses Act (ADU mandate)applies
Qualifying condition
HB 1466 is a statewide ADU mandate with no population or geography threshold; applies to all Maryland jurisdictions including unincorporated areas of Montgomery County. Local-implementation conformance deadline October 1, 2026. Montgomery County population 1,062,061 (2020 Census) — no threshold applies. North Potomac is an unincorporated CDP governed by Montgomery County Code; the preemption applies at the county level and flows through to this CDP.
Effect
Montgomery County must allow ADUs statewide by Oct 1, 2026 per HB 1466; affects residential zones R-200, R-90, R-60, RE-1, RE-2, RE-2C
Non-applicable laws (3)
MD HEAA 2024 — Md. Code Ann., Land Use §§7-501 to 7-508does_not_apply
Qualifying condition
HEAA requires TOD: parcel ≤0.75 mi from MARC, Metro, or Light Rail station OR ≤0.5 mi from high-frequency bus. Nearest WMATA Metro stations to North Potomac CDP (centroid lat 39.097/-77.239) are Shady Grove (≈4.0 mi SE) and White Flint (≈5.0 mi SE), both outside the 0.75 mi transit proximity trigger. No MARC station within proximity. HEAA does not apply to North Potomac unless a qualifying parcel is within 0.75 mi of a qualifying stop — no such parcel cluster identified in the CDP core.
Effect
Not applicable; HEAA density floor and by-right multifamily do not override local (county) zoning in North Potomac absent transit proximity
MD HB 599/SB 477 Missing Middle (status: misattributed_not_enacted)does_not_apply
Qualifying condition
Per preemptions.json correction (date_updated 2026-05-20): actual MD HB 599 (2024) is the Housing & Community Development Financing Act, not a zoning preemption. Statewide missing-middle preemption (HB 778) did NOT meet crossover in 2026 session. No statewide missing-middle preemption is currently in force.
Effect
Not applicable; no enacted statewide missing-middle preemption as of 2026-06-02
MD HB 894/SB 389 — Maryland Transit and Housing Opportunity Act (status: pending)does_not_apply
Qualifying condition
HB 894/SB 389 is encoded as pending (enrolled-chapter codification not confirmed as of 2026-05-18). Even if enacted, it targets frequent-rail station areas (WMATA, Purple Line, Baltimore Metro/LR, MARC Penn). North Potomac CDP has no qualifying rail station within trigger distance (see HEAA check above). Does not apply.
Effect
Not applicable pending enactment and due to lack of qualifying transit

Quirks & notes

  • North Potomac is an unincorporated CDP in Montgomery County — no municipal zoning authority. All zoning is under Montgomery County Code Chapter 59 (eff. 2014-10-30) administered by M-NCPPC (Maryland-National Capital Park and Planning Commission).
  • CRN/CRT/CR zone designations encode total FAR, commercial FAR (C), residential FAR (R), and max height (H) in a single string per §4.5.2.A.2 — e.g. CRN-0.25 C-0.25 R-0.0 H-35 means total FAR 0.25, max commercial FAR 0.25, no residential FAR, max height 35ft. Each map designation is a unique zone.
  • RT-8.0, RT-10.0, PD-2, PD-3 are legacy zones retained from the pre-2014 ordinance under Article 59-8 — these cannot be newly applied after October 30, 2014, but remain in force on previously-zoned properties. These are mapped within North Potomac according to the GIS query.
  • R-200 max height is variable by lot size: lots ≥40,000 sf max 50ft; lots 25,000-39,999 sf max 40-45ft; lots 15,000-24,999 sf max 35-40ft; lots <15,000 sf max 30-35ft. Source: DevelopmentStandardsForR200Zone.pdf §4.4.7.
  • GIS source verified: mcatlas.org/arcgis5/rest/services/backgrounds/Zoning_background/MapServer/27 — 8,567 features county-wide; sample centroid within North Potomac bbox at -77.292/39.103 (0.006° lat, 0.053° lon from CDP centroid). All 3 GIS gates passed.
  • The zoning map layer attribute BEGINDATE=1414627200000 corresponds to epoch ms for October 30, 2014 — confirming the GIS records reflect the Ch.59 2014 effective date.
  • LSC (Life Sciences Center) zones appear in North Potomac area — unusual for a suburban residential CDP; associated with corridor development along I-270 and Shady Grove Life Sciences Center area. Significant industrial/office presence reflects proximity to the biotech corridor.
