Yountville Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

Yountville’s zoning is codified in Title 17 (Zoning) of the Yountville Municipal Code; Title 17 is the town’s principal land‑use law and states the ordinance’s purpose, applicability and administration. Title 17 is organized into chapters for districts, procedures, and standards and is administered by the Town Council, the Zoning and Design Review Board, the Planning Officer and the Planning & Building Department (§ 17.04.010; § 17.04.070) . The code ties zoning decisions to the General Plan and to Master Development Plans where those apply (§ 17.04.030; § 17.32.050) .

How Yountville's code is organized

• Title name and scope: Title 17 is the town’s Zoning Ordinance and applies to “all land uses, structures, subdivisions, and development within the Town” (§ 17.04.010; § 17.04.040) .
• Table of contents: Title 17 is divided into Divisions and Chapters that group (1) applicability and definitions, (2) zoning districts and district rules, (3) objective development standards, and (4) procedural chapters (use permits, design review, Master Development Plans, appeals, nonconforming uses, definitions) (see the Title 17 table of contents and chapter headings) (§ 17.04.010; Chapter list in Title 17) .
• Where key rules live:
  • District rules (per‑district permitted uses and district tables) are in each district chapter (for example, RS in Chapter 17.20 and RM‑2 in Chapter 17.26) (§ 17.20.010; § 17.26.010) .
  • Citywide objective standards and definitions (setbacks, measurement rules, auxiliary structure rules, FAR exemptions/bonuses) are in Divisions 3–4 and specific sections cited by district tables (for example, FAR rules cross‑refer to § 17.100.030 and § 17.100.040) (§ 17.20.050; references to § 17.100.030 & § 17.100.040) .
  • Procedural chapters include design review (Chapter 17.188), Master Development Plans (Chapter 17.192), use permits (Chapter 17.200), administrative permits (Chapter 17.196), appeals (Chapter 17.224), and nonconforming uses (Chapter 17.232) (§ 17.26.020; § 17.32.050; Chapter references in Title 17) .

(Note: this overview links the town’s code conceptually — see Yountville Zoning for the Title name and start point.)

Zoning district families (what each district label means)

The code’s Use Table and legend list the town’s district families: A (Agricultural), RS (Single‑Family Residential), RM / RM‑2 (Mixed Residential / Mixed Residential‑2), H (Old Town Historic), MPR (Master Planned Residential), MHP (Mobile Home Park), PP (Parks & Playfields), PF (Public Facilities), PC (Primary Commercial), RSC (Residential‑Scaled Commercial), OTC (Old Town Commercial), RC (Retained Commercial), MU (Mixed‑Use Overlay) and PD (Planned Development) — these codes and the Use Table are defined in § 17.12.010 and mirrored in each district chapter (§ 17.12.010; chapter headings for each district) .

• Example district rules you will see in the individual district chapters:
  • RS (Single‑Family Residential) sets baseline setbacks and height limits and points parking to Chapter 17.116 (§ 17.20.050) .
  • RM‑2 (Mixed Residential‑2) sets density ranges, 60% maximum lot coverage and district FARs (duplex/multifamily FAR up to 0.40) in its development table (§ 17.26.050) .
  • H (Old Town Historic) explicitly allows accessory dwellings and other residential uses but treats multifamily and some changes as use‑permit matters (§ 17.28.030; § 17.28.040) .
  • Commercial districts (for example PC and RSC) carry their own FAR caps and may offer specific FAR bonuses for defined reuse/alteration programs (§ 17.48.060; § 17.64.060) .

Citywide development standards (high‑level orientation)

• Setbacks and encroachments: district development tables set the basic front/side/rear yard depths; many district tables refer readers to the setback measurement and encroachment rules in Chapter 17.108 and auxiliary‑structure setbacks in Chapter 17.112 (for example, the RS table lists front 20 ft, side 5 ft, rear 20 ft) (§ 17.20.050; § 17.108 reference; § 17.112 reference) .
  • For accessory and special two‑unit configurations, Title 17 has tailored setback rules (see two‑dwelling development standards in § 17.158.010 and small‑home lot/cluster rules in § 17.162.050) (§ 17.158.010; § 17.162.050) .
• Height: district tables declare maximum heights and top‑story limits (e.g., one‑story: 15 ft to plate / 20 ft to peak; two‑story: 20 ft to plate / 28 ft to peak for many residential districts) and note specific exceptions or block‑level two‑story controls (§ 17.20.050; § 17.26.050) .
• Lot coverage and FAR: a typical residential maximum lot coverage of 60% appears in multiple districts (RM‑2 and others) and district FAR caps are spelled out in each district table (for example, RS, RM, RM‑2 tables) (§ 17.26.050; § 17.20.050) .
• Parking: district tables defer to the town’s off‑street parking and loading chapter; the RS district table explicitly points to Chapter 17.116 for the number and design of required stalls — see the town’s parking rules for stall counts, compact‑car allowances and loading rules (§ 17.20.050; Chapter reference to 17.116) . (See Yountville Parking for the detailed parking matrix.)
• Design expectations for commercial and mixed‑use projects: the code adds mandatory nonresidential design standards to guide design review and allow waivers only through the design review process (§ 17.72.010) . (See Yountville Development Standards and Yountville Design Review for the design guidance and process.)

Specific plans & overlays

• Master Development Plans / Planned Development: where a site is subject to a Master Development Plan (often used in MPR and PD contexts), the Master Development Plan governs allowable uses, densities and standards; if the plan is silent, Title 17 standards apply (§ 17.32.050; Chapter 17.192) .
• Overlays: Title 17 recognizes overlay designations (for example the Affordable Housing Overlay referenced across district tables) and the Zoning Map shows overlays; overlay rules are identified in the map and in Chapter cross‑references (see § 17.08.050–.060 on map and overlay provisions and Chapter 17.80 on the Affordable Housing Overlay) (§ 17.08.040–.060; cross‑references to Chapter 17.80) . (See Yountville Overlay Districts for maps and overlay rules.)
• Historic protections: some project types (notably small‑lot and demolition proposals) trigger historic resource review and may require a historic assessment prepared to State DPR standards before demolition is approved; Title 17 cross‑references the town’s historic preservation rules when demolition or replacement is proposed (§ 17.162.060; reference to Section 15.28.010) . (See Yountville Historic Preservation for the historic review rules.)

Building permits & review (the typical path)

• Who administers applications: Day‑to‑day administration is handled by the Planning & Building Department and the Planning Officer; higher level approvals come from the Zoning & Design Review Board and Town Council per the roles listed in § 17.04.070 (§ 17.04.070) .
• Common review triggers:
  • “By‑right” permits for uses listed as permitted in the district table require ministerial building permits but must meet objective development standards in the district chapter (§ 17.12.010; district chapters) .
  • Design review is required for new or modified nonresidential and many residential exterior changes (Title 17 directs applicants to Chapter 17.188 when design review is required) (§ 17.26.020; § 17.24.020) . (See Yountville Design Review.)
  • Use permits and administrative use permits are regulated by Chapter 17.200 and Chapter 17.196 respectively; appeals are governed by Chapter 17.224 (§ 17.12.010; Chapter references) .
• Building code and technical compliance: Title 17 defers to the California building standards and the California Building Code in technical matters (for example, some setback exceptions between units are allowed only to the extent the California Building Code permits) — local dimensional/clearance rules are written with those code references in mind (§ 17.162.050.K.2) . (See California Building Standards Code.)
• Special procedures: subdivisions, tentative maps, Master Development Plans and Planned Development projects have additional filing and map requirements (see Chapter 17.192 for Master Development Plans and Title 16 for subdivision standards) (§ 17.32.050; § 17.162.050.J) .

State housing law in Yountville

Yountville’s Title 17 frequently cross‑references and defers to state law where state statutes apply. A few concrete touchpoints:

• Accessory dwelling units (ADUs) are explicitly permitted in multiple residential and historic districts with a cross‑reference to the ADU chapter; the Use Table lists ADUs as a permitted use and points to Chapter 17.156 (Accessory Dwelling Units) for the local ADU rules (§ 17.12.010; district chapters such as § 17.28.030 and § 17.26.030) . (See Yountville ADUs and California ADU law for state rules that also apply.)
• Density bonus and affordable housing: density bonuses and inclusionary/affordable housing rules are handled in Chapter 17.160; district tables repeatedly point to Chapter 17.160 for density bonus programs and to § 17.100.040 for FAR bonuses tied to affordable housing (§ 17.20.050; § 17.26.050; § 17.100.040) .
• State preemption / conflict: where local provisions conflict with state statutes, the code notes that state law controls — for example, the two‑dwelling residential development rules include a preemption sentence that Government Code § 65852.21 prevails in case of conflict (§ 17.158.010.U) . For other state housing laws (SB 9, density bonus, ADU statutes) the local code either cross‑references state law directly or defers to state law where applicable (see the ADU cross‑references and the two‑dwelling preemption clause) (§ 17.12.010; § 17.158.010.U) . (See California housing laws and California ADU law for the state frameworks.)

Practical orientation — how to find the rule that applies to your project

1. Find the parcel’s zoning on the Town’s zoning map and note the district code (legend shows RS, RM, H, PC, RSC, OTC, RC, MPR, PD, etc.) (§ 17.12.010 legend; § 17.08.010 map rules) .
2. Read that district’s chapter table for permitted uses, development standards (setbacks, heights, FAR, lot coverage) and references to other chapters for parking, landscaping and auxiliary‑structure rules (each district table contains these cross‑references; see, for example, § 17.20.050 for RS and § 17.26.050 for RM‑2) . (Use the Yountville Development Standards page for consolidated district numbers.)
3. Check whether your change triggers design review, a use permit, a Master Development Plan or subdivision review; those procedural triggers are listed in district general conditions and in Chapters 17.188, 17.192 and 17.200 (§ 17.24.020; § 17.26.020; Chapter references) . (See Yountville Design Review.)
4. Confirm technical construction requirements (fire sprinklers, defensible space, building‑code clearances) with the Building Division and the California Building Standards Code references cited in Title 17 (§ 17.162.050; cross‑references to Chapters 15.32 and others) . (See California Building Standards Code.)
5. If your project aims to rely on state housing statutes (ADU, SB 9, density bonus), treat the local code and state law together — Title 17 contains explicit cross‑references and a preemption clause where conflicts may arise (§ 17.12.010; § 17.158.010.U) . (See California housing laws and California ADU law.)

Information Gaps / Items to verify with the Planning Department

• The uploaded Title 17 excerpts reference many chapters (for example Chapter 17.116 for parking, Chapter 17.156 for ADUs, and Chapter 17.188 for design review) but the full text of those chapters was not included in the retrieved excerpts here. Confirm numeric parking ratios, ADU objective standards and the complete design‑review thresholds with the Town’s Planning & Building Department (see § 17.20.050 and § 17.12.010 for the cross‑references) .
• SB 9 / Government Code‑driven owner‑occupancy and lot‑split rules are not explicitly parsed in the retrieved excerpts beyond the two‑dwelling preemption note (§ 17.158.010.U) — verify the town’s current objective rules and any ministerial SB 9 implementation with staff (§ 17.158.010.U) .
