Sacramento — Overlay Districts

Last reviewed: July 2, 2026

Overview

Overlay districts in Sacramento are additional zoning layers that sit on top of underlying zones and impose additional or alternate requirements for special situations (for example, proximity to the American River, the Executive Airport, transit stations, or concentrated solid-waste uses). The ordinance defines an overlay as a district that "encompasses one or more underlying zones and imposes additional or alternate requirements," and requires you to follow both the underlying zone and the overlay provisions where they apply. See § 17.300.010 .

This page focuses only on what the Sacramento Planning and Development Code says about overlay and special-planning districts (how they apply, what they typically allow or prohibit, and the code sections you will need to check). For related practical rules (setbacks, parking, or design review) consult the city's technical pages on Sacramento Development Standards, Sacramento Parking, and Sacramento Design Review. For ADU questions or building-code requirements consult Sacramento ADUs and the California Building Standards Code.

How Sacramento treats overlays (core rules)

• Overlays are applied in addition to, not instead of, the underlying zone unless the overlay explicitly says otherwise; the overlay designation appears after the underlying zone on the official zoning map and signals additional rules apply. See § 17.300.010 and analogous applicablity clauses in overlay chapters such as § 17.340.020 (TO) and § 17.332.030 (PC) .
• Where the overlay chapter conflicts with other provisions in the Development Code, the overlay chapter’s provisions generally prevail (the overlay can supersede underlying rules as specified). See examples in § 17.340.020.B and § 17.442.030 .
• Many overlays either: (a) allow the same uses as the underlying zone but add conditions; or (b) list prohibited uses or special restrictions tailored to protect a resource (e.g., the American River Parkway) or public safety (e.g., airport environs). See the use rules in each overlay chapter (examples below).

District-by-district breakdown (what you must check first)

Note: for every parcel, first confirm whether an overlay designation appears after the underlying zone on the official zoning map and then read the cited overlay chapter.

EA — Executive Airport Overlay (EA-1 through EA-4)

• Purpose: To protect public health, safety, and air navigation around Sacramento Executive Airport; to implement Airport Land Use Commission guidance and the Executive Airport Comprehensive Land Use Plan. See § 17.312.010 .
• Typical permitted uses: Generally the uses of the underlying zone apply, but the overlay creates restrictive categories and conditions; some incompatible uses may continue as legal nonconforming uses but cannot be expanded. See § 17.312.030–040 .
• Key restrictions / dimensional or operation-related standards:
  • Height and navigable-airspace protections; height and reflective-light restrictions intended to avoid hazards to aircraft (no objects that reflect sunlight toward aircraft, or flashing lights that interfere with approach paths). See § 17.312.040 and § 17.312.090 .
  • Special discretionary review for certain uses; the overlay establishes restrictive categories and a permit process for changes that could affect airport operations. See § 17.312.070 (discretionary permits) .
• Where it applies: Applied to property around Sacramento Executive Airport; the overlay classes (EA-1–EA-4) and specific boundaries are set on the zoning map and via the CLUP referral rules. See § 17.312.020 .

PC — Parkway Corridor Overlay (PC)

• Purpose: Protect the American River Parkway’s scenic, recreational, fishery, and wildlife values and implement the American River Parkway plan. See § 17.332.010 .
• Typical permitted uses: Uses permitted in the underlying zone, except where the PC chapter specifically prohibits a use or imposes conditions. See § 17.332.040 .
• Key dimensional and design standards:
  • Minimum building setback: No building within 25 feet of the reference line; accessory buildings for single- and two-unit residences may be within 15 feet. See § 17.332.070.F .
  • Fence or wall: A 6-foot masonry wall or 6-foot woven wire fence is required along the reference line where a parcel abuts it. See § 17.332.070.G.1 .
  • Tree planting strip: 10-foot tree strip required adjacent to the landward side of the fence/wall; species and planting size regulated by the city landscape architect. See § 17.332.070.G.2 .
  • Exterior lighting: Must be shielded and directed away from the Parkway. See § 17.332.070.H .
• Where it applies: Property zoned ARP-F (American River Parkway) and other areas the Council designates where development might affect the Parkway. See § 17.332.020–030 .

SWR — Solid Waste Restricted Overlay (SWR)

• Purpose: Limit establishment and expansion of heavy solid-waste facilities in concentrated areas to reduce traffic, air-quality impacts, and public-health hazards. See § 17.336.010 .
• Typical permitted uses: Unless expressly restricted, uses of the underlying zone are permitted; however, new hazardous waste facilities, new solid waste landfills, and new solid waste transfer stations are prohibited within the SWR. See § 17.336.030 .
• Key restrictions / nonconforming rules:
  • Existing hazardous-waste, landfill, or transfer-station uses cannot be modified, expanded, or altered except in very limited ways and only via conditional use permit procedures that cannot increase capacity (no variance to increase tonnage/volume). See § 17.336.030.B–C and § 17.336.040 (nonconforming rules) .
• Where it applies: Areas the City Council determines have heavy concentrations of solid-waste facilities; the SWR suffix appears after the underlying zone on the zoning map. See § 17.336.020 .

TO — Transit Overlay (TO)

• Purpose: Encourage moderate- to high-density residential and mixed-use development within walking distance of existing or proposed light rail transit stations; allow increased heights/densities for residential projects and restrict uses that do not support transit ridership. See § 17.340.010 .
• Typical permitted uses: Uses of the underlying RMX or C-2 zone generally apply; some uses are restricted and certain residential-friendly uses (e.g., hotels) are explicitly permitted in the TO variant. See § 17.340.030–040 .
• Key standards and limitations:
  • Applicability radius: The TO may be applied to RMX and C-2 property located within one-half mile of an existing or proposed LRT station; measurement rules are specified for existing vs. proposed stations. See § 17.340.020.A .
  • Nonresidential cap: In the RMX-TO zone, nonresidential uses may occupy a maximum of 50% of the gross square footage of each new building (residential component required for increased intensities). See § 17.340.030.B .
• Where it applies: Properties mapped as RMX-TO or C-2-TO on the official zoning map; the TO suffix indicates the overlay’s additional requirements apply. See § 17.340.020.B .

SPDs — Special Planning Districts (examples and general rules)

• Purpose and treatment: An SPD replaces or supplements routine zoning rules with area-specific provisions tailored to the district, to achieve design, environmental, preservation, or economic objectives. The general SPD rules explain that the SPD designation means property is subject to the SPD chapter in addition to the underlying zone, and SPD provisions prevail over conflicting portions of the development code. See § 17.400.010–020 and § 17.400.030–040 .
• Example: ESC SPD (Entertainment and Sports Complex)
  • Boundaries, conflicts, uses: The ESC SPD chapter defines boundaries, states SPD rules prevail over conflicting code, and generally bases permitted uses on the C-3 zone while listing conditional and prohibited uses (e.g., adult entertainment, gas stations, auto repair are prohibited). See § 17.442.020–040 .
  • Ground-floor retail and special use lists are included in the SPD chapter; many ESC uses require conditional use permits or Planning Director approval. See § 17.442.040 .
• Example: Freeport SPD
  • Purpose: Preserve the historic “delta river town” character and set SPD-specific development standards. The Freeport SPD’s provisions apply in addition to the underlying zone and prevail over conflicting rules. See § 17.448.010–040 .
• Planned Unit Developments (PUDs) are a related special district category; a PUD designation subjects property to the PUD chapter, schematic plans, and development guidelines and requires site-plan conformity before building permits are issued. See § 17.452.020–030 .

Quick reference table — overlays and the most decision-relevant standards

Practical guidance (plain-English synthesis & comparisons)

• Start at the map: confirm the parcel’s base zone and whether an overlay suffix (for example, -TO, PC, SWR, EA, SPD) is shown after the zone on the official zoning map — the suffix means that the overlay chapter applies in addition to the underlying zone. See § 17.300.010 and the specific overlay applicability language such as § 17.340.020.B and § 17.332.030.A .
• Overlays are mostly additive: in many overlays the uses permitted in the underlying zone remain permitted, but overlays often add prohibitions or impose conditions that will drive project design or require additional permits (e.g., conditional use permits, design review). See § 17.332.040 and § 17.336.030.A . For review processes, check the overlay-specific permit sections and the city’s design-review rules at Sacramento Design Review.
• Where an overlay creates stricter physical controls (setbacks, walls, planting strips, lighting), those will typically be in the overlay chapter (e.g., PC minimum setbacks, fencing, and tree-strip requirements). See § 17.332.070.F–G and use the city’s Sacramento Development Standards page to coordinate technical details.
• Transit (TO) overlays are frequently used to promote housing and mixed-use development near stations but also to limit auto-oriented uses; verify the one-half mile radius rule and the 50% nonresidential cap for RMX-TO projects in § 17.340.020–030 . Check Sacramento Parking early in design because transit overlays often affect parking expectations on a project.
• If you see an SPD or PUD designation, expect area-specific schematic plans and development guidelines to govern site layout, and a requirement that building permits conform to the approved schematic/site plans. See § 17.452.020.B and § 17.400.020–030 .

Checklist (what an applicant must satisfy)

• Confirm overlay suffix on the official zoning map (overlay appears after the base zone) — § 17.300.010 .
• Read the overlay chapter that corresponds to that suffix (EA, PC, SWR, TO, or SPD) and note any express prohibitions, required setbacks, or required improvements — e.g., § 17.332.070 (PC), § 17.336.030 (SWR), § 17.340.020–030 (TO) .
• Determine whether your proposed use is permitted by right in the underlying zone or whether a conditional use permit or other discretionary approval is required — see the overlay’s “Uses” subsection (many overlays defer to the underlying zone with stated exceptions) — e.g., § 17.332.040 and § 17.336.030.A .
• If the overlay requires additional design controls (setbacks, walls, planting strips, lighting), incorporate them into the site plan — e.g., § 17.332.070.F–H .
• Confirm whether the project must meet SPD schematic plans or PUD development guidelines and schedule pre-submittal review with Planning staff — see § 17.452.020.B and § 17.400.030 .
• Coordinate on parking and related technical standards with Public Works/Planning (see Sacramento Parking).
• Verify nonconforming use restrictions and whether your proposal would be treated as an expansion or modification subject to overlay-specific nonconforming rules (notably SWR has stricter nonconforming limits) — see § 17.336.040 .

Risks & Ambiguities

Plain-English Summary

If your property has an overlay suffix (for example, -TO, PC, SWR, EA, or an SPD/PUD label), the city’s overlay chapter applies in addition to the base zoning rules and may add new prohibitions, setbacks, or permit requirements — read the overlay’s chapter (the code references below) and verify applicability on the official zoning map before designing a project.
