Definition
A conditional use permit (CUP) — also called a special use permit or use permit in some California jurisdictions — is a type of discretionary land use approval that allows a use to operate in a zoning district where that use is not automatically permitted by right, but is allowed when the agency exercises judgment about whether the use can be made compatible with the surrounding area through the imposition of conditions.
The "conditional" in conditional use permit refers to the conditions the agency attaches to the approval — requirements like hours of operation, noise limits, screening, parking arrangements, or operational standards that the applicant must meet to receive and keep the permit.
How a CUP Differs from a Permitted Use
Within any zoning district, uses fall into three categories:
- Permitted by right: Automatically allowed if the project meets the zone's objective standards. No public hearing, no agency judgment required.
- Conditionally permitted (requires a CUP): May be allowed after the agency conducts a public hearing and exercises discretion to determine whether the use is appropriate at this specific location with conditions.
- Prohibited: Not allowed in this zone at all.
A drive-through restaurant might be permitted by right in a highway commercial zone but require a CUP in a neighborhood commercial zone, because of the traffic and noise concerns it raises in a residential-adjacent setting. The CUP process allows the agency to tailor the approval to the specific site and context.
The CUP Process
- The applicant submits a CUP application describing the proposed use and operating characteristics.
- The planning department reviews the application for completeness and analyzes whether the use meets the findings required for CUP approval.
- A public hearing is held — typically before the planning commission — and neighbors are notified.
- The planning commission makes findings (usually that the use is consistent with the general plan, compatible with the surrounding area, and that conditions can adequately address impacts) and either approves with conditions, denies, or continues the hearing.
- The decision may be appealed to the city council.
CUPs and California Housing Law
California's recent housing laws have significantly curtailed the CUP requirement for residential development. Many housing types that previously required a CUP — including multifamily housing near transit, ADUs, and duplexes — are now entitled to ministerial approval under state law, without any public hearing or discretionary review. Cities that continue to require CUPs for these uses may be violating state law preemption. Planning staff should audit their zoning code to ensure CUP requirements are not being applied to uses that state law now entitles to by-right approval.
The shift from discretionary to ministerial approval is one of the defining trends of California housing law. Legislaide helps planning departments identify which CUP requirements in their zoning codes have been preempted by state law — before an applicant files a lawsuit to find out.
Frequently Asked Questions
What is a conditional use permit?
A conditional use permit (CUP) is a discretionary land use approval that allows a use in a zoning district where it is not automatically permitted by right, but may be allowed if the agency exercises judgment that it can be made compatible with surrounding uses through imposed conditions.
What findings are required for a CUP?
Typical required findings include: the use is consistent with the general plan, the use is compatible with surrounding land uses, and conditions of approval can adequately address impacts. Exact findings vary by local ordinance, but must be supported by evidence in the administrative record.
How does a CUP differ from a permitted use?
A permitted use is approved automatically if it meets objective standards — no hearing required. A CUP requires a public hearing, discretionary agency judgment, and specific written findings. Neighbors may comment, and the decision may be appealed.
Is a CUP required for housing projects in California?
Increasingly no. California housing law prohibits cities from requiring a CUP for many housing types — including multifamily housing near transit under SB 423, ADUs, and duplexes under SB 9. Cities that still require CUPs for these uses may be violating state preemption, exposing themselves to litigation and attorney fee awards.
Can a CUP be revoked?
Yes. Most zoning codes allow a CUP to be revoked if the holder violates conditions of approval. Revocation typically requires a public hearing with notice to the permit holder and an opportunity to cure violations before revocation is finalized. The holder may appeal a revocation decision.
