SB-4 streamlines zoning and land-use approvals but does not alter or exempt projects from existing subdivision requirements under the Subdivision Map Act, ensuring compliance remains required.

If a project creates new legal parcels (tract/parcel maps), they must still file a map.

Are SB‑4 Projects Exempt From Filing a Tract Map?

No.  SB‑4 does not exempt a church or nonprofit from filing a tract map if the project intends to subdivide land.

Why? — SB‑4 Streamlines Use Approval, Not Parcel Division

SB‑4 guarantees:

  • Use‑by‑right approval for qualifying 100% affordable Housing projects
  • Streamlined, ministerial approval (no hearings, no CUP, no CEQA challenges)
  • Zoning overrides for sites owned by churches or nonprofit colleges

These facts are confirmed in multiple sources:

  • SB‑4 “provides a streamlined process… overriding local zoning restrictions” and guarantees by‑right approval when objective standards are met.
  • SB‑4 projects receive ministerial approval without discretionary permits or CEQA, providing certainty and predictability for your development process.
  • SB‑4 is a use-by-right development statute, not a subdivision statute—no part of SB‑4 references subdivision exemptions or changes to the Subdivision Map Act.

Nowhere in SB‑4 is there:

  • a waiver of the Subdivision Map Act,
  • an exemption from tentative/parcel maps,
  • authorization to create parcels without maps, or
  • language superseding Gov. Code § 66410 et seq.

Because the Subdivision Map Act governs all land divisions, and SB‑4 does not amend it, map requirements remain fully intact.

If the SB‑4 project does NOT create new parcels:

No tract or parcel map is required.
Most SB‑4 developments are vertical multifamily affordable buildings on a single existing parcel; thus, no subdivision is involved.

In these cases, cities issue:

  • ministerial site plan approvals,
  • ministerial building permits,
    without any map requirement.

If the SB‑4 project DOES create new parcels:

A tract map or parcel map is still required.

Examples include:

  • Creating separate lots for phases
  • Condo map (airspace subdivision)
  • Townhome lots
  • Fee‑simple small‑lot Housing format
  • Subdividing church property into multiple legal parcels

Because SB‑4 does not remove subdivision requirements, the project must comply with:

  • Tentative map filing
  • Final map or parcel map
  • Surveying
  • Dedications/easements
  • Public works/engineering review

All of this occurs ministerially—cities cannot impose discretionary review or hearings.

⚖️ How Cities Must Process Maps Under SB‑4

While a tract/parcel map is required when land is subdivided, SB‑4 requires cities to process any necessary ministerial approvals, similar to the SB‑684 and SB‑9 frameworks.

This means:

  • No public hearings
  • No CEQA
  • No discretionary conditions
  • Objective standards only
  • No appeals
    (consistent with SB‑4’s ministerial mandate and zoning overrides).

Cities must still:

  • Check the map for technical compliance,
  • Apply public‑works engineering standards,
  • Ensure safe access, utilities, dedications, etc.
    But may not use the map process to block the project.

Bottom Line

SB‑4; no to Subdivision Exemption

SB‑4 streamlines land‑use approvals, but if your affordable Housing project divides land or creates fee‑simple units, you must still file a tract/parcel map under the Subdivision Map Act.

SB‑4 ensures the city cannot use the map process to slow, block, or litigate the project.
