Naming convention
use-type-index

Base district codes are two-letter use-type tokens (RS, RI, RT, RM residential; CL, CT, CC, DCC, DMU, DN, OBC commercial; I industrial; P/PQP public). Overlay districts use a colon-prefix convention (:PD, :BF, :AH, :HS, :ED, :AC, :SC, :PE) to distinguish overlay from base on zoning maps (e.g., 'RM:AH' = Multifamily Residential with Affordable Housing overlay). Density ranges are set by General Plan Pod density tied to each base district; zoning carries those ranges forward via Pod designation rather than hard du/ac caps in the zoning text. | sub_flags_raw=[density-range-by-district, downtown-specific-plan-overlay, post-2022-general-plan]

Worth knowing
  • Wine Country Preservation Overlay (WCPO) does NOT exist at the City of Napa level. The prior v1 profile fabricated WCPO, Downtown Napa Mixed-Use Overlay (DNMU), River District Adaptive Reuse Overlay (RDARO), Agricultural Transition Zone Overlay (ATZO), and Medical/Wellness Corridor Overlay (MWCO). The actual Napa Title 17 overlays are :BF, :AH, :HS, :PD, :ED, :AC, :SC, :PE, :AF. Napa County (separate jurisdiction) has the Ag Preserve (since 1968, Napa County Code Title 18) and scenic-protection provisions — but those are COUNTY, not CITY. Research-request callers who need wine-country ag protection should query Napa County, not City of Napa. — [c§17 overlay chapter index (§17.33 AC, §17.35 BF, §17.37 AH, §17.40 HS, §17.42 PD, §17.44 PE, §17.46 SC, ED in Title 17)]
  • Colon-prefix overlay naming convention. Napa writes overlays with a leading colon (:BF, :AH, :HS, :PD, :ED, :AC, :SC, :PE) on zoning maps and in code to distinguish them from base district codes. A map label like 'DCC:BF' means Downtown Core Commercial base with Building Form overlay; 'RM:AH' means Multifamily Residential with Affordable Housing overlay. This convention is unusual among CA cities studied — recommend promoting to _references/naming-conventions.md. — [c§17 (overlay chapters throughout Title 17)]
  • :AH Affordable Housing Overlay sets a MINIMUM density floor, not a maximum. For low-density residential districts the floor is 90% of the site's Pod density range; for multifamily/mixed-use/master plan the floor is 75%. This is opposite to density-bonus laws that raise ceilings — :AH forces projects to hit a minimum density to ensure site productivity for affordable housing. Priority processing and fee deferral (per Ch. 15.94) until occupancy. — [c§17.37]

State preemptions

CA-ADU-GC§66411.7-66411.8applies
Qualifying condition
All CA cities. Napa's RS, RI, RT, RM, and mixed-use districts must permit ADUs by right per state law. RS district explicitly permits ADUs per §17.08.010. | title=Accessory Dwelling Units / JADUs ; effect_on_city=Ministerial approval with 60-day shot clock; detached ADUs up to 1,200 sf; JADUs up to 500 sf; no owner-occupancy requirement beyond statute; up to 8 ADUs on qualifying multifamily lots under SB 1211 (eff. 2025-01-01). Preempts any Napa Title 17 provision that would impose a minimum lot size, owner-occupancy beyond statute, or parking within 1/2 mi of transit / historic district / existing-structure ADU.
CA-SB9-GC§65852.21-66411.7applies
Qualifying condition
Napa is a CA general-law city with single-family districts (RS, RI, RT). SB 9 applies per-parcel conditional on exclusions. Napa has FEMA SFHA in the Napa River corridor (parcel-specific exclusion), identified hillside areas (HS overlay at ≥15% slope) that partially overlap with CalFire VHFHSZ (per-parcel), and historic neighborhoods (RT district) — but Napa has no designated historic district in Title 17 that would categorically exclude SB 9 (historic neighborhoods are a use-type designation, not a Mills-Act / National Register district excluded by statute). Napa is an inland city — no coastal zone. | title=SB 9 — California HOME Act (Lot Splits + Duplex Conversion) ; effect_on_city=Ministerial up-to-4-units on qualifying RS/RI parcels (lot split + duplex per resulting lot). City cannot require lot size >40% of original, side/rear setbacks >4 ft, or FAR <0.8 on resulting lots. SB 450 (eff. 2024-07-01) strengthens ministerial procedural limits. HS overlay slope analysis may still apply where site slope ≥15%. ; per_parcel_conditional=True ; exclusions=['FEMA SFHA (Napa River corridor per-parcel)', 'CalFire VHFHSZ (HS overlay parcels per-parcel)', 'coastal zone (N/A — inland)', 'designated historic districts (none in Title 17; RT is not a statutory historic district)']
CA-DensityBonus-GC§65915applies
Qualifying condition
Statewide. Applies to any Napa project meeting affordability thresholds (5% VLI, 10% LI, 10% moderate for-sale, or 100% affordable). AB 1287 allows stacking up to 100% density bonus. Stacks with :AH overlay density floor (which raises minimum not maximum). | title=State Density Bonus Law + AB 1287 (2023) ; effect_on_city=Up to 100% density bonus (AB 1287 stacked) on RM, DCC, DMU, DN, OBC projects with residential components. Can waive base du_ac maxima, max_height_ft (within reason), and base setbacks as concessions/incentives (1 per 10% VLI, 2 per 20%, 3 per 30%). State §65915(p) parking ratios preempt §17.52 on affordable components. :BF overlay height ceiling (DSP §4.7.2) may still govern downtown projects unless state waiver triggered.
CA-AB2097applies
Qualifying condition
Napa is served by Vine Transit (operated by Napa Valley Transportation Authority) with downtown Napa Transit Center at Pearl/Soscol and Route 29 Napa VINE Express to Vallejo/BART. Whether Vine stops qualify as 'major transit stop' under PRC §21064.3 depends on 15-min peak headway at bus-intersection qualifying corridors. Downtown Napa Transit Center and the Wine Train station (if rail service qualifies) may anchor qualifying buffers. Napa County Airport does NOT qualify (not a transit stop). | title=AB 2097 — Parking Mandate Elimination Near Transit ; effect_on_city=No minimum parking may be required for residential, commercial, or mixed-use within 1/2 mile of qualifying Vine Transit Center / major bus-intersection stops. Preempts §17.52 parking ratios within buffer. Stacks with :PE Parking Exempt overlay where mapped.
CA-SB423-GC§65913.4applies
Qualifying condition
SB 423 applies to sites zoned residential or mixed-use in cities not meeting their RHNA share OR HCD-non-compliant. Napa's 6th-cycle Housing Element (2023–2031, ABAG allocation, RHNA 2,669 units) is HCD-certified as of 2023-12-05. Applies to RS/RI/RT/RM, DCC/DMU/DN/OBC corridor parcels (per AB 2011 overlap). CalFire VHFHSZ and recent tenant-displacement sites excluded. | title=SB 423 — Streamlined Ministerial Multifamily Approval (extends SB 35, 2024–2036) ; effect_on_city=If Napa is at the 10% affordability trigger per HCD APR: ministerial by-right approval for qualifying multifamily ≥10% affordable (LI rental / moderate for-sale). 50%+ affordable bypasses design review. Prevailing wage + skilled-and-trained workforce apply for 10+ unit projects. ; search_performed=HCD APR SB 423 determination list not fetched live (JS-rendered dashboard). ; tier=under_review
Retrieval issue
HCD APR dashboard is JS-rendered; not fetchable within budget.
CA-AB2011-GC§65912.100applies
Qualifying condition
Napa has commercially-zoned parcels along defined corridors (Soscol Ave, Imola Ave, Trancas St, First St, Silverado Trail within city limits) that may qualify as 'commercial corridors' under AB 2011. 100% affordable projects by-right on any commercial site; mixed-income by-right on corridor sites (excludes industrial-only and office-only). | title=AB 2011 — Affordable Housing and High Road Jobs Act ; effect_on_city=Ministerial approval for qualifying multifamily on CL, CT, CC, DCC, DMU, OBC corridor sites. 100% affordable bypasses discretionary review. Minimum density cannot be less than Napa's default. Overlaps with SB 423 (developer chooses pathway). Prevailing wage required.
Non-applicable laws (2)
CA-BuildersRemedy-GC§65589.5(d)(5)applies
Qualifying condition
Napa's 6th-cycle Housing Element (2023–2031) was HCD-certified on 2023-12-05 (adopted 2023-10-17). While HCD certified, Builder's Remedy is DORMANT for this cycle. If Napa falls out of compliance (e.g., fails annual APR or rezone commitments), Builder's Remedy re-activates. | title=Builder's Remedy (Housing Accountability Act) ; effect_on_city=Dormant. Projects must comply with Napa Title 17 and overlays. If Napa loses HCD compliance mid-cycle, projects with 20% LI or 100% moderate-income would bypass zoning. AB 1893 (2024) codifies procedural requirements.
CA-SB10under_review
Qualifying condition
SB 10 is permissive — authorizes but does not require cities to zone up to 10 units/parcel near transit or urban infill via simple resolution (CEQA-exempt). No evidence Napa City Council has adopted an SB 10 resolution; 2040 General Plan (adopted 2022-10-18) relies on standard rezone path. | title=SB 10 — Local Upzoning Authorization ; effect_on_city=None unless/until Napa adopts an SB 10 resolution.

Priority processing and fee deferral (per Ch. 15.94) until occupancy. — [c§17.37]
  • :BF Building Form overlay pulls dimensional standards (height, step-backs, setbacks, development intensity) from Downtown Specific Plan Section 4.7.2 Building Form Zones rather than from Title 17 itself. Result: downtown height/massing is governed by DSP §4.7.2, not by DCC/DMU/DN/OBC base district tables. Any title-17-only reading of downtown Napa will miss the operative standard. — [c§17.35 + Downtown Specific Plan §4.7.2]
  • :HS Hillside overlay triggers at ≥15% slope (any base district) and requires a slope analysis per §17.30.040(H) to determine site density. HS provisions supersede underlying district in conflict. 2014 South Napa Earthquake (M6.0) aftermath did not produce a city-level seismic/URM overlay in Title 17 — URM retrofit is handled under Title 15 Building Standards, not Title 17 Zoning. — [c§17.40 + §17.30.040(H)]
  • :PD Planned Development overlay allows variation from base district standards EXCEPT density and FAR ranges — those are preserved from the underlying principal district. This is a narrower PD than typical CA cities (which often allow density modulation via PD). Design review and superior-design findings required; phased projects must be independently viable. — [c§17.42]
  • General Plan Pod density system. Base residential districts (RS, RI, RT, RM) carry density ranges from the 2040 General Plan Pod designation rather than hard du/ac caps in the zoning text. 2040 GP Pod categories: Very Low (1–2), Low (3–8), Traditional Residential (2–12), Medium (8–18), High (18–40) du/ac. Project density = site's Pod designation, not district code alone.

Formulas

Definitions

height
Measured per CA Building Code from grade to highest point; BF overlay uses Downtown Specific Plan Section 4.7.2 Building Form Zones to set height within the DSP area (overrides base).
density
Minimum density on a site shall be no lower than a percentage of the Pod density range. For Low Density Residential (RS/RI/RT) districts, minimum density = 90% of the site's Pod density range. For Multifamily (RM), Mixed Use, or Master Plan districts, minimum density = 75% of the site's Pod density range, calculated by taking the General Plan density range, multiplying by 75%, and adding to the low end of the range (per :AH overlay formula at c§17.37). General Plan Pod density categories (2040 GP): Very Low (1–2 du/ac), Low (3–8 du/ac), Traditional Residential (2–12 du/ac), Medium (8–18 du/ac), High (18–40 du/ac).
setback
From property line to building face; historic neighborhoods (RT) allow flexibility in street setbacks and yards to support compatible design (c§17.08).
lot_coverage
Building footprint / lot area
far
Gross floor area / lot area
du_ac
Dwelling units per acre (gross for General Plan Pod designation; net for project-level density calculations)
parking
Per unit residential; per sf commercial. AB 2097 eliminates minimums within 1/2 mile of major transit.
