Sacramento County — Historic Preservation

Last reviewed: July 6, 2026

Overview

In unincorporated Sacramento County, the Sacramento County Zoning Code (SZC) does not establish a single countywide Historic Preservation overlay. Instead, historic resources are managed through a mix of project-specific zoning tools, use-specific standards, and eligibility screens in the base code. Key touchpoints include Special Planning Area ordinances, Planned Development combining zones, use regulations for agricultural stands and wineries/breweries, and SB 9 eligibility rules. This page focuses on what the SZC itself requires and how it intersects with related processes like zoning, overlay districts, design review, and development standards.

The SZC’s most consistent countywide trigger is simple: if a building is 100 years old or older and you propose renovation as part of certain uses, you must submit photos for County screening or commission a qualified architectural historian’s study; if deemed significant, you must preserve the structure in place and follow the Secretary of the Interior’s Standards. § 3.4.7; § 3.4.8.F.7

How the SZC treats historic resources in unincorporated areas

• Use-based historic triggers (countywide)

  • Field Retail Stands, Farm Stands, Produce Stands, Agricultural Markets: For buildings 100+ years old that are proposed for renovation, applicants must either submit photographs for Planning and Environmental Review (PER) staff triage or obtain a historic architectural study by a qualified professional. If PER determines the structure is a significant historic resource, it must be preserved in situ and any modifications must conform to the Secretary of the Interior’s Standards. § 3.4.7 (Advisory; mitigation for historic buildings)
  • Small Wineries / Specialty & Craft Breweries: The same study-or-photos pathway applies, and if significance is found, in-situ preservation and Secretary’s Standards are required. § 3.4.8.F.7
  • Large Wineries/Breweries: Must comply with the Small Wineries standards except for production limits—so the § 3.4.8.F.7 historic-resource process also carries through here via § 3.4.9.C. § 3.4.9.C; § 3.4.8.F.7

• SB 9 screening for historic properties

  • SB 9 two-unit or urban lot split projects are ineligible on property within a State-inventory historic district or on a County-designated landmark or historic property. § 5.4.7.A.1.c

• Project-specific zoning often used to conserve historic character

  • Special Planning Area (SPA) Zoning District: Created when an area has unique environmental, historic, or architectural features that require custom standards. Each SPA ordinance must include reasons for adoption, permitted uses, and development standards. § 4.10.1; § 4.10.2.B; § 4.10.2.E
  • Planned Development combining tools: The PD and County‑initiated PDC tools exist partly to regulate areas with unique historic or architectural features through tailored use lists and standards. § 408-01; § 408-03; § 408-20; § 408-23

• Floodplain code definition of “Historic Building”

  • The Floodplain Management chapter defines “Historic Building” to include National Register listings, contributors in registered districts, State listings, and locally listed resources, including contributors in Delta legacy communities. § 902-36

• Design Review interface

  • The County uses its design review process to evaluate proposals against context-sensitive standards; this process is intended to accommodate unique community character in unincorporated areas. § 5.1.1

District-by-district notes (where Historic Preservation touches zoning)

Special Planning Area (SPA)

• Purpose: Protect areas with unique historic or architectural features by adopting site-specific standards. § 4.10.1
• Typical permitted uses: Set by each SPA ordinance; must list permitted uses and tailored development standards. § 4.10.2.E
• Key dimensional standards: Vary by SPA; the SPA ordinance must specify yards, intensity, parking, landscaping, and signs. § 4.10.2.E
• Where it applies: Only within an adopted SPA boundary in the unincorporated County. § 4.10.2.C

Planned Development (PD) Combining Zone

• Purpose: Provide flexibility and protect public interests while accommodating unique site conditions; can be paired with historic conservation goals. § 408-01
• Typical permitted uses: All uses allowed in the base zone(s), including uses requiring a CUP—if included in the PD development plan. § 408-03.b
• Key dimensional standards: May deviate from base standards if the Board finds objectives are achieved (e.g., through superior design or open space). § 408-03.d, § 408-03.e
• Where it applies: Where a PD is combined with a base zone in unincorporated areas. § 408-01

County‑Initiated Planned Development (PDC)

• Purpose: Specifically acknowledges areas with unique historic or architectural features and provides a method to regulate them. § 408-20
• Typical permitted uses and standards: Must include a permitted-use list, yards, intensity, parking, landscaping, signs, and other appropriate design standards. § 408-23.a
• Where it applies: Only where adopted by ordinance in unincorporated areas. § 408-21

Flood Combining (F)

• Purpose: Applies where land is subject to the 100‑year flood; intersects historic preservation by defining “Historic Building,” which can affect how floodplain rules are interpreted for older resources. § 902-36; Table 2.1 (F Combining District summary)
• Typical permitted uses and standards: Floodplain elevation rules apply; if no public water/sewer, minimum one-acre lots. Table 2.1 (F Combining District)
• Where it applies: Where the F combining designation is mapped in unincorporated areas. Table 2.1

Agricultural and Agricultural-Residential Districts (AG/AR) — Historic triggers for Stands/Markets

• Purpose connection: Field and farm stand regulations include mandatory steps to evaluate and protect potentially historic buildings (100+ years) proposed for renovation. § 3.4.7 (historic mitigation pathway)
• Typical uses involved: Field Retail Stands, Farm Stands, Produce Stands, Agricultural Markets. § 3.4.7
• Key standards: Historic photo submittal or study; in-situ preservation and Secretary’s Standards if significant. § 3.4.7

Agricultural, Commercial, Mixed Use, and Industrial Districts — Historic triggers for Wineries/Breweries

• Purpose connection: Small wineries/breweries are allowed in these districts with a historic-resource review pathway for 100+ year buildings under renovation; large facilities carry these standards over. § 3.4.8.F.7; § 3.4.9.C
• Related standards: Event and parking rules for wineries/breweries are addressed separately; note that large wineries/breweries have distinct parking provisions. § 3.4.9.E (parking for large wineries/breweries)

Most decision-relevant standards and screens

Practical guidance

• Start with your base zoning and any mapped overlays via the County’s zoning and overlay districts pages. If your parcel lies in an SPA or PD/PDC area, those adopted ordinances control detailed rules. § 1.7.3.A; § 4.10.3
• If your project involves a structure that is 100+ years old and will be renovated as part of a farm stand or winery/brewery, budget time for PER staff screening or a qualified architectural historian’s study. If it is significant, plan to preserve in place and use the Secretary’s Standards. § 3.4.7; § 3.4.8.F.7
• SB 9 housing requests must pass the historic-resource screen before proceeding. § 5.4.7.A.1.c
• Coordinate early with design review to reconcile context-sensitive design with development standards, signage, and parking requirements. § 5.1.1
• If you’re in a flood area and working on a listed/contributing resource, confirm how the floodplain’s “Historic Building” definition factors into your entitlement path. § 902-36 (definition)

Checklist

• Confirm you are in the unincorporated County and identify base zoning and any SPA/PD/PDC overlays. § 1.7.3.A; § 4.10.2.C; § 408-21
• For farm/produce stands or winery/brewery projects, determine if any structure involved is 100+ years old and proposed for renovation. § 3.4.7; § 3.4.8.F.7
• If 100+ years: submit photographs to PER for triage, or commission a qualified architectural historian’s study; be prepared to preserve in situ and follow the Secretary’s Standards if significant. § 3.4.7; § 3.4.8.F.7
• If pursuing SB 9, verify your parcel is not within a historic district on the State Inventory and not a County-designated landmark/historic property. § 5.4.7.A.1.c
• If in an SPA or PD/PDC, obtain the applicable ordinance for permitted uses, dimensional standards, and any historic-specific provisions. § 4.10.2.E; § 408-23.a
• If in a mapped flood area, confirm whether the structure meets the “Historic Building” definition and discuss implications with PER and floodplain staff. § 902-36
• Coordinate early with design review on objective design and context. § 5.1.1

Risks & Ambiguities

Information Gaps

• Countywide historic landmark designation procedures, historic district mapping, or a dedicated Historic Preservation overlay in the SZC: Not found in retrieved materials.
• Any SZC incentives or relief tied specifically to historic rehabilitation (e.g., relief from certain signage or parking standards): Not found in retrieved materials.
• Parcel-specific SPA or PD/PDC ordinances that include bespoke historic design controls: Verify with the jurisdiction.

Plain-English Summary

In unincorporated Sacramento County, there isn’t a one-size-fits-all historic overlay; instead, historic protections show up where you’d actually do work. If you plan to renovate a 100+ year-old building as part of a farm stand or winery/brewery, you must provide photos or commission a historic study, and if it’s significant you’ll need to preserve it in place and follow the Secretary of the Interior’s Standards. SB 9 housing is not allowed on designated historic sites or in State-inventory historic districts. For areas with special historic character, site-specific SPA or PD/PDC ordinances set the rules you’ll follow.
