Davis Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

Davis organizes its land-use and zoning rules in Chapter 40 of the Davis Municipal Code (the City's zoning chapter), which implements the General Plan and several area-specific codes including a Downtown-specific code. The zoning chapter sets the district map, permit paths (ministerial, administrative, discretionary), citywide development standards, design-review rules, overlay districts, and processes for planned developments and variances. For the City’s statement of purpose and structure of the zoning chapter see § 40.01.040 .

How Davis's code is organized

• The primary zoning body of rules is Chapter 40 of the Davis Municipal Code (the zoning chapter); its purpose/principles are stated in § 40.01.040 . Link: Davis Zoning (/us/california/davis/zoning).
• Downtown-specific rules are implemented as the "Downtown Code" in Articles 40.13 and 40.14 (the Downtown Davis Specific Plan is implemented through those articles) — see § 40.13.040 and § 40.13.050 .
• Zoning articles and numbered sections are the basic navigation units: district articles (e.g., R‑districts, commercial districts), overlay articles, and procedural articles (site-plan review, conditional uses, planned developments, variances). Key permit & procedure articles include the administrative use permit procedures in Article 40.30A (e.g., § 40.30A.020), site plan & architectural approval in Article 40.31, and Planned Development in Article 40.22 .

Zoning district families (citywide snapshot)

Davis deploys base zoning districts and overlay/special-area standards. Representative, Davis‑named districts you will see in Chapter 40:

• Planned Development (P‑D) — Article 40.22 sets the P‑D purpose, applicability, required findings and the two‑step preliminary/final P‑D application process (§ 40.22.010 – § 40.22.140) .
• Downtown code districts: C‑I, C‑D, C‑C, MU‑D and the DTRN overlay (Downtown/Traditional Neighborhood) — implemented by Articles 40.13/40.14 and mapped on the official zoning map (§ 40.13.050, § 40.13.060) .
• Commercial/industrial districts such as A‑C (Auto‑Commercial) with site standards (lot area, coverage, setbacks, height) specified in § 40.16.050 .
• Residential family types: multiple residential district provisions and transitional districts (for example R‑T) appear through Article 40.10 and referenced R‑district sections (see cross‑references to residential standards in § 40.10.010–.020 and the residential-area sections referenced elsewhere) .
• Overlay/special zones: e.g., the High Density Residential (HDR) Overlay District (mapped for specific sites such as 4600 Fermi Place) with development standards for lot area, height, setbacks, FAR and usable open space (§ 40.09A.020–.090) .

(For a quick entry point to how overlay and special districts are grouped, see the City's overlay rules and maps in Chapter 40; link: Davis Overlay Districts (/us/california/davis/overlay-districts).)

Citywide development standards (what to expect in the code)

Davis separates district-specific numeric standards from citywide procedural/design rules. Representative, concrete examples from the code:

• Where the code places district standards: base numeric standards live in the zoning district articles (e.g., setbacks/height/lot coverage in the A‑C article § 40.16.050 and in downtown/mixed‑use articles § 40.15.080 for lot coverage and FAR) .
• Setbacks: many district rules specify front/side/rear setbacks; for example A‑C front yard 25 ft, side yard 10 ft (larger where abutting residential), rear 10 ft (§ 40.16.050(c)) . The Downtown and traditional neighborhood areas use tailored setback rules and averaging methods in the Downtown Code (see § 40.13.060 and related Downtown sections) .
• Height: typical non‑downtown principal‑building height examples include two stories / 35 ft for A‑C (§ 40.16.050(d)) and two‑story / 30 ft ceilings in certain residential districts (see cross references, e.g., § 40.04.050 summarizes general height caps) .
• Lot coverage / FAR: Downtown and mixed‑use articles set explicit FAR and lot‑coverage regimes with base/bonus FAR tables (Base FAR 1.5, maximum total 2.0 with bonuses such as underground parking or plazas) and lot coverage rules differentiated by use (§ 40.15.080) .
• Parking and bicycle parking: off‑street parking and loading are regulated in Article 40.25 and related bicycle parking standards are cross‑referenced in overlay rules (e.g., HDR requires bicycle parking per § 40.25A.060) — see § 40.09A.080(h) and related parking chapters. Link: Davis Parking (/us/california/davis/parking) .
• Landscaping, screening and open‑space minima are required in multiple district standards (for example A‑C requires minimum landscape area 10% of site — § 40.16.060; HDR requires usable open space minimums — § 40.09A.080(g)) .
• Minor modifications: the Director can approve limited relaxations (up to 10% reductions or increases for setbacks, lot coverage, height, parking, etc.) under the minor modification rules (§ 40.27.080) when criteria and findings are met . For the City's consolidated development standards entry point, see Davis Development Standards (/us/california/davis/development-standards).

Design & discretionary review

• Design review / site plan & architectural approval lives in Article 40.31. The Director’s review functions include siting, landscaping, parking layout, loading, screening, exterior elevations, signs and lighting — see the explicit list in § 40.31.040 . Link: Davis Design Review (/us/california/davis/design-review).
• The code implements a Citywide Objective Design Standards program for projects required by state law to meet objective standards; the City Council may adopt these by resolution and they prevail over conflicting local objective standards (§ 40.31.060) .
• Downtown zones have their own tailored urban‑design standards and rules that supersede some general exception sections; see Articles 40.13/40.14 for massing, frontage types and specific sign rules (§ 40.13.030, § 40.13.060) .

Specific plans, overlays & special areas

• The Downtown Davis Specific Plan is implemented by the Downtown Code (Articles 40.13 and 40.14) and mapped to specific Downtown zones (§ 40.13.050–.070) .
• The code includes project‑level overlays (for example the HDR Overlay at 4600 Fermi Place with tailored density, height 60 ft, lot area minimum 7,500 sf, lot coverage 50%, and FAR 2.0 — see § 40.09A.020–.090) .
• Planned developments (P‑D) permit tailored standards where the P‑D preliminary plan (and subsequent final P‑D) become the regulation for the parcel; see § 40.22.050–.140 for procedure and required findings .
• Historic resources and special overlay subjects are handled by specific articles (for example Article 40.23 for historic resources, and individual overlays with their own sections — cross‑references appear throughout the Downtown and overlay articles) . Link: Davis Historic Preservation (/us/california/davis/historic-preservation).

Building permits & review: the typical path

• Quick guides & flowcharts in the Downtown Code show high‑level permit paths; projects route through ministerial building‑permit‑only processes, administrative use permits, or discretionary public‑hearing tracks depending on the use and code triggers (§ 40.13.030 and procedural articles 40.30–40.36) .
• Administrative approvals: an Administrative Use Permit process exists (Article 40.30A) where the Director can approve certain uses administratively, with public notice and appeal rights to the Planning Commission (§ 40.30A.020–.050) .
• Discretionary approvals (Conditional Use Permits, Planned Development final approvals, variances) follow the public‑hearing procedures in Articles 40.30 and 40.36 and require findings; P‑D approvals require demonstrating conformity with the General Plan and timely construction expectations (§ 40.22.110, § 40.36.040 et seq.) .
• Design review and site‑plan review approvals (Article 40.31) are required for most non‑single‑family projects; the Director administers many items but some projects are routed to the Planning Commission per the code lists (§ 40.31.040) .
• Enforcement: all City permits must comply with Chapter 40; permits issued contrary to the code are void and enforcement provisions (including nuisance declarations and abatement) are in Article 40.37 (§ 40.37.010–.020) .
• For building‑level code requirements, the Davis Code cross‑references the City's Building Code (Chapter 8/Title references) and state codes; see ADU provisions requiring building permits and conformance to the building code (§ 40.26.450(e)(2) and related ADU text) . Link: California Building Standards Code (/us/california/building-codes).

State housing law in Davis — how statewide rules are implemented locally

Summary: Davis's zoning chapter explicitly cross‑references state housing law in several places; it implements ministerial ADU rules, allows for density bonus mechanisms tied to local affordable‑housing rules, and provides for objective design‑standard paths where state law requires them.

• ADUs (Accessory Dwelling Units)

  • Davis implements both ministerial ADUs and a separate non‑ministerial ADU track. Ministerial ADUs are governed by § 40.26.450 (ministerial ADUs) and the non‑ministerial ADU standards and the administrative‑use‑permit pathway are in § 40.26.460 (maximum non‑ministerial ADU size 1,200 sf, typical setbacks and height caps such as 30 ft max for non‑ministerial ADUs; ministerial ADU development standards including 4‑ft side/rear minimums appear in § 40.26.450 and in the ADU text) . Link: Davis ADUs (/us/california/davis/adu).
  • ADU provisions expressly defer to and incorporate state ADU law (citing Government Code cross references in the code text) and require building permits and conformance with the City's building code (§ 40.26.450(e)(2); § 40.26.460(b)(3)) .
  • The Davis ADU rules also specify fee, utility‑connection and impact‑fee treatment consistent with state rules (e.g., ADUs < 750 sf exempt from impact fees; will‑serve letter requirements) — see § 40.26.450(h) and § 40.26.450(e) .
  • For state ADU details beyond Davis text, see California ADU law resources; Davis ADU sections explicitly reference the state code where applicable (the local code integrates state cross references) .

• Density bonus & affordable‑housing incentives

  • The code allows density‑bonus deviations consistent with state law and local affordable housing rules (the code cross‑references state density bonus law and Davis's Article 18.05 local affordable‑housing/inclusionary rules — see § 40.27.110 and cross‑references in overlay ministerial pathways § 40.09A.110) .
  • The specific mechanics and local inclusionary requirements live in Article 18.05 (Affordable Housing); Chapter 40 permits exceptions consistent with state law and Article 18.05. (Text of Article 18.05 should be consulted for the exact local inclusionary percentages and affordability definitions — Article 18.05 is referenced in the zoning chapter) .

• SB 9 / two‑unit and lot‑split ministerial pathways

  • The Davis zoning text as retrieved does not contain an explicit SB‑9‑labeled section or a local "urban lot split"/SB‑9 ministerial lot‑split procedure in the snippets provided. The zoning chapter does provide ministerial and administrative tracks (Articles 40.30A, 40.31), but if you need SB‑9 specific local implementation details (such as objective standards, subdivision map processing, or local objective objective standards adopted to regulate SB‑9 ministerial approvals), those specific code provisions were Not found in retrieved materials — verify with the City or the full municipal code for explicit SB‑9 implementing ordinances. (Verify: Not found in retrieved materials.)

• Rent control / tenant protections

  • I did not find explicit rent‑control or municipal rent‑stabilization language in the retrieved Chapter 40 snippets. If you are checking whether Davis imposes rent control, consult the municipal code and municipal ordinances outside Chapter 40 (if any) or contact the City — the zoning chapter does not itself establish rent control rules in the excerpts retrieved. (Verify: Not found in retrieved materials.)

Practical orientation & developer checklist (city‑wide)

• Start at the zoning map and Chapter 40 to identify the parcel's base district and any overlays (Downtown Code or HDR/OZ) — the Downtown Code overrides/more specific rules are in Articles 40.13/40.14 (§ 40.13.060) .
• Confirm numeric standards in the applicable district article (setbacks/heights/lot coverage/FAR) — sample district references: § 40.16.050 for A‑C setbacks/height/coverage; § 40.15.080 for Downtown FAR/lot coverage rules; § 40.09A.080 for HDR overlay standards .
• Identify permit path: building‑permit‑only (ministerial), administrative (Article 40.30A) or discretionary (CUP/Planning Commission/City Council) and whether design review (Article 40.31) is required — see § 40.30A.020, § 40.31.040 and the Quick Code Guides (§ 40.13.030) .
• If you seek small adjustments use the Minor Modification rule (limited 10% relaxations) under § 40.27.080; for larger deviations use variance or revised P‑D/conditional‑use processes (§ 40.27.080, Article 40.33 referenced throughout) .
• Expect ADU proposals to be handled under the ministerial ADU standard § 40.26.450 when they meet state‑law objective criteria, or under the non‑ministerial ADU rules § 40.26.460 with an Administrative Use Permit when they do not meet ministerial thresholds .

Information gaps / items to verify with the City

• Local SB‑9 implementation language (explicit local SB‑9/ministerial urban lot‑split procedures) was not found in the retrieved Chapter 40 snippets; confirm whether Davis adopted a dedicated SB‑9 implementing ordinance or relies on State default rules. (Not found in retrieved materials.)
• Full text of Article 18.05 (Affordable Housing / inclusionary rules) was referenced by Chapter 40 but the complete Article 18.05 provisions were not included in the retrieved excerpts; consult Article 18.05 directly for exact inclusionary rates and density‑bonus mechanics. (Referenced; consult Article 18.05.)
• Any municipal rent‑stabilization or rental‑housing ordinances outside Chapter 40 were not located in the retrieved material. (Not found in retrieved materials.)
