Overview

Code type
euclidean
Naming convention
mixed

Bellevue runs a euclidean code with classic R-x density-encoded single-family / multifamily districts (R-1 = 1 du/ac, R-30 = 30 du/ac), commercial (NB, CB, GC), office (PO, O, OLB), light industrial (LI), and four subarea-specific special districts (Downtown LUC 20.25A, BelRed LUC 20.25D, Wilburton LUC 20.25Q, Eastgate LUC 20.25P). With Ordinance 6851 effective 2025-07-01 the residential district codes are being renamed (R-1 -> LL-1, R-1.8 -> LL-2, R-2.5 -> SR-1, R-3.5 -> SR-2, R-4 -> SR-3, R-5 -> SR-4, R-7.5 -> LDR-1, R-10 -> LDR-2, R-15 -> LDR-3, R-20 -> MDR-1, R-30 -> MDR-2) while keeping dimensional standards in Chart 20.20.010. Middle housing (4/6/9 units per lot tiered by transit proximity) is governed by LUC 20.20.538. | naming_convention_raw=Hybrid: legacy single-family/multifamily letter+number system (R-1 through R-30 = du/ac density encoding) is being renamed to LL-x / SR-x / LDR-x / MDR-x descriptive codes per Ordinance 6851 middle housing implementation; downtown / BelRed / Wilburton / Eastgate use subarea-specific DT-/BR-/etc. codes per LUC 20.25A/D/Q/P ; sub_flags_raw=[pacific-northwest, transit-rich-tier1, subarea-based-special-districts] ; narrative_ref=narratives/bellevue-wa/drain-20260518T072625-wa-02b.json

Worth knowing
  • With Ordinance 6851 effective 2025-07-01, Bellevue is renaming its residential land use districts from the legacy density-encoded R-x system (R-1 = 1 du/ac, R-30 = 30 du/ac) to descriptive code (LL-1, LL-2, SR-1 through SR-4, LDR-1 through LDR-3, MDR-1, MDR-2). Dimensional standards (Chart 20.20.010) are largely unchanged; the rename is descriptive and ties to the new middle-housing categorization in LUC 20.20.538. Profile carries both new code (district.code = LL-1 etc.) and legacy_code field for back-compatibility. Existing zoning maps, ordinances, and references will use legacy codes during transition.
  • Sound Transit 2 Line (East Link) opened 2024-04-27 with eight stations inside Bellevue or at its border: South Bellevue, East Main, Bellevue Downtown, Wilburton, Spring District/120th, BelRed/130th, Overlake Village (Bellevue/Redmond border), Redmond Technology. These are fixed-rail stations with ROW-separated platforms and qualify as 'major transit stops' under RCW 36.70A.030. This triggers (a) HB 1110 6-plex tier in any SF residential lot within 1/4 mi walk of major transit OR with 2 affordable units; (b) HB 1110 9-plex tier per LUC 20.20.538.C.1 Note 2 within 1/2 mi of major transit; (c) parking waiver for ADU + middle housing within 1/2 mi of major transit (LUC 20.20.120.C.5, 20.20.590.F.4). The transit-triggered density is geographically substantial: rough 1/2 mi buffer around 8 stations covers a significant share of Downtown / Wilburton / BelRed / Spring District as well as parts of LDR-1 (formerly R-7.5) neighborhoods within walking distance.
  • Bellevue's LUC Chart 20.20.010 carries three independent coverage limits per parcel: maximum lot coverage by structures (e.g. 35% in R-1, 40% in R-5+), maximum impervious surface (e.g. 45% in R-1, 65% in R-10), and maximum hard surface coverage (e.g. 75% with 80%/90% transition). Per Note 37, all areas of lot coverage by structures count toward impervious surface (unless exempted under LUC 20.20.460), and impervious surface counts toward hard surface. This three-tier constraint is more granular than typical WA cities and constrains driveway / patio / sport-court placement on top of building footprint.

Quirks & notes

  • With Ordinance 6851 effective 2025-07-01, Bellevue is renaming its residential land use districts from the legacy density-encoded R-x system (R-1 = 1 du/ac, R-30 = 30 du/ac) to descriptive code (LL-1, LL-2, SR-1 through SR-4, LDR-1 through LDR-3, MDR-1, MDR-2). Dimensional standards (Chart 20.20.010) are largely unchanged; the rename is descriptive and ties to the new middle-housing categorization in LUC 20.20.538. Profile carries both new code (district.code = LL-1 etc.) and legacy_code field for back-compatibility. Existing zoning maps, ordinances, and references will use legacy codes during transition.
  • Sound Transit 2 Line (East Link) opened 2024-04-27 with eight stations inside Bellevue or at its border: South Bellevue, East Main, Bellevue Downtown, Wilburton, Spring District/120th, BelRed/130th, Overlake Village (Bellevue/Redmond border), Redmond Technology. These are fixed-rail stations with ROW-separated platforms and qualify as 'major transit stops' under RCW 36.70A.030. This triggers (a) HB 1110 6-plex tier in any SF residential lot within 1/4 mi walk of major transit OR with 2 affordable units; (b) HB 1110 9-plex tier per LUC 20.20.538.C.1 Note 2 within 1/2 mi of major transit; (c) parking waiver for ADU + middle housing within 1/2 mi of major transit (LUC 20.20.120.C.5, 20.20.590.F.4). The transit-triggered density is geographically substantial: rough 1/2 mi buffer around 8 stations covers a significant share of Downtown / Wilburton / BelRed / Spring District as well as parts of LDR-1 (formerly R-7.5) neighborhoods within walking distance.
  • Bellevue's LUC Chart 20.20.010 carries three independent coverage limits per parcel: maximum lot coverage by structures (e.g. 35% in R-1, 40% in R-5+), maximum impervious surface (e.g. 45% in R-1, 65% in R-10), and maximum hard surface coverage (e.g. 75% with 80%/90% transition). Per Note 37, all areas of lot coverage by structures count toward impervious surface (unless exempted under LUC 20.20.460), and impervious surface counts toward hard surface. This three-tier constraint is more granular than typical WA cities and constrains driveway / patio / sport-court placement on top of building footprint.
  • Per LUC Chart 20.20.010 Note 1, side yard setback in R-30 (now MDR-2) districts increases to 20 ft on any side yard where structure exceeds 30 ft above finished grade. Base side yard is 5 ft. This creates a tiered building envelope — first 30 ft of building height uses 5 ft side yards, anything above triggers 20 ft side yards. Tower-on-podium typologies must account for the step-up.
  • Bellevue does not use a single FAR per residential district. Instead LUC Table 20.20.390.B.1 sets a sliding FAR by unit count on the lot: 1 unit = 0.3 FAR for lots >=10,000 sf or 0.5 FAR for lots <10,000 sf; 2 units = 0.5; 3 units = 0.6; 4 units = 0.7; 5 units = 0.75; 6 units = 0.9; 7 units = 1.0; 8 units = 1.2; 9 units = 1.4. Cottage housing developments may utilize the highest FAR with no max-unit limit. Note 43 to Chart 20.20.010 also imposes an FAR-0.5 threshold for SF: development exceeding 0.5 FAR must maintain >=7.5 ft side yard structure setback and either daylight-plane or 5-ft second-story stepback on each side facing a side yard. Subdivision-built SF and PUDs are exempt from FAR threshold.
  • Per LUC 20.25A.070, the maximum permitted FAR in the Downtown subarea districts (DT-O-1, DT-O-2, DT-MU, DT-OLB, DT-R) may only be achieved through participation in the FAR Amenity Incentive System — a public-benefit-trading system where developers contribute affordable housing, public open space, public art, sustainable design, or other amenities in exchange for FAR bonuses above the base allowance. Underlying district base FAR is significantly below max FAR. DT-MU Civic Center area east of 111th Ave NE between NE 4th and NE 8th is the highest-FAR tier. LUC 20.25A.075 also imposes tower / stepback requirements.
  • The canonical code platform bellevue.municipal.codes is Cloudflare-protected (returns HTTP 403 with Cloudflare Turnstile challenge for curl, WebFetch, raw HTTP). Specific dimensional charts (Chart 20.20.010 for commercial/office/industrial values; Chart 20.25A.060 for downtown; Chart 20.25D.080 for BelRed; Chart 20.25Q.060 for Wilburton; LUC 20.25H.035 for critical area buffers) cannot be retrieved by agent tooling. The February 2025 LUCA draft PDF at bellevuewa.gov/sites/default/files/media/pdf_document/2025/dsd-02242025-middle-housing-luca-february-draft.pdf is reachable and provides Chart 20.20.010 residential dimensional values plus the full text of LUC 20.20.120 (ADU), LUC 20.20.250 (cottage), LUC 20.20.252 (courtyard), LUC 20.20.390 (FAR), and LUC 20.20.538 (middle housing). Commercial / office / industrial / downtown / BelRed dimensional values remain partial in this profile pending an alternate retrieval path (Playwright with stealth or city-Planning PDF mirror).
  • Within the Downtown (LUC 20.25A), BelRed (LUC 20.25D), Wilburton (LUC 20.25Q), and Eastgate (LUC 20.25P) subarea boundaries, the base Chart 20.20.010 dimensional standards are entirely replaced by the subarea's own dimensional chart (20.25A.060 / 20.25D.080 / 20.25Q.060 / 20.25P.060). Parcels within these subareas do NOT use the R-x / LL-x / SR-x / LDR-x / MDR-x base zoning; they use DT-/BR-/WIL-/EG- subarea codes only. Additionally, LUC 20.10.380 Evergreen Highlands establishes 4 separate performance areas (EH-A through EH-D) as 'separate land use districts' replacing standard residential standards within that subarea boundary.
