Class 32 CEQA exemption: the five infill conditions and the evidence behind them
Class 32 (CEQA Guidelines §15332) exempts infill projects that meet five conditions: general plan and zoning consistency; a site within city limits of five acres or less, substantially surrounded by urban uses; no value as habitat for endangered, rare or threatened species; no significant traffic, noise, air or water quality effects; and adequate utilities and public services.
The five conditions and the evidence each needs
All five must be met, and courts review an agency's factual finding that a project fits for substantial evidence in the record. The record is what carries a Class 32 exemption.
| §15332 | Condition | Evidence that answers it |
|---|---|---|
| (a) | Consistent with the general plan designation, “all applicable general plan policies,” and the zoning designation and regulations | The designations, a policy-by-policy consistency table, and the zoning standards (height, setbacks, parking) the plans meet |
| (b) | Within city limits, on a site of no more than five acres, substantially surrounded by urban uses | A city boundary map, the site area, and a description and aerial photos of what lies on each side |
| (c) | No value as habitat for endangered, rare or threatened species | A biologist's memo: site visit, photos, and a search of state species records |
| (d) | No significant effects relating to traffic, noise, air quality or water quality | Technical studies: transportation (vehicle miles traveled), construction and operational noise, air quality against the air district's thresholds, and stormwater and water quality |
| (e) | Can be adequately served by all required utilities and public services | Will-serve letters from water and sewer providers, and confirmation of fire, police and other services |
Condition (b): “substantially surrounded by urban uses”
In Working Families of Monterey County v. King City Planning Commission (2024) 106 Cal.App.5th 833, King City used Class 32 for an 18,187 sq ft Grocery Outlet on a 1.6-acre former car sales lot next to Highway 101. Challengers argued the city, with a population of 13,332, was not an “urbanized area,” and that §15332 should be read with the statutory definitions of “infill site,” “urbanized area” and “qualified urban uses” (Public Resources Code §§21061.3, 21071, 21072) and Guidelines §15387. The Sixth District rejected that reading.
It then found substantial evidence in the city's environmental assessment: a description of the surrounding land uses and two aerial photographs showing commercial buildings on two sides, Sheriff's Department buildings next to a vacant lot on a third, and a cemetery on the fourth. The lesson for the record is plain: name and photograph what is on every side of the site.
Condition (d): traffic means vehicle miles traveled
Guidelines §15064.3(a) makes vehicle miles traveled “generally” the most appropriate measure of transportation impacts and says that, except for roadway capacity projects, “a project's effect on automobile delay shall not constitute a significant environmental impact.” Under §15064.3(b)(1), land use projects within half a mile of an existing major transit stop, or a stop along an existing high quality transit corridor, “should be presumed” to cause a less than significant transportation impact. Noise, air quality and water quality have no such presumption, so each needs its own analysis.
The exceptions still apply
Meeting all five conditions is not the end. The location exception in §15300.2(a) names Classes 3, 4, 5, 6 and 11, not 32. The others are written more broadly: (b) bars exemptions where successive projects of the same type in the same place have a significant cumulative impact, and (c) to (f) say a categorical exemption “shall not be used” where there is a reasonable possibility of a significant effect due to unusual circumstances, damage to scenic resources on a state scenic highway, a site on the Government Code §65962.5 (Cortese) list, or a substantial adverse change to a historical resource. Berkeley Hillside Preservation v. City of Berkeley (2015), the Supreme Court's unusual circumstances case, involved a house approved under both Class 3 and Class 32; see the Class 3 guide and the exceptions guide.
Class 32 or AB 130's statutory exemption?
AB 130 (2025) added Public Resources Code §21080.66, a statutory exemption for housing that overlaps Class 32 but is built differently.
| Class 32 (§15332) | PRC §21080.66 | |
|---|---|---|
| Kind | Categorical exemption in the Guidelines | Statutory exemption in the Public Resources Code |
| Projects | Any infill development, housing or not | Housing development projects only, with limits on transient lodging |
| Site size | Five acres or less | 20 acres or less (four for builder's remedy projects) |
| Where | Within city limits | Within an incorporated municipality, or a Census Bureau urban area |
| Setting | Substantially surrounded by urban uses | Previously developed with an urban use, or urban uses on at least 75% of the perimeter, 75% of a quarter-mile radius, or three of four sides plus two-thirds of the perimeter |
| Consistency | General plan designation and policies, and zoning | General plan, zoning and any local coastal program, judged by whether a reasonable person could conclude it is consistent; a density bonus is not an inconsistency |
| Other conditions | Habitat, the four effects in (d), services | At least half the housing element density standard, the site exclusions of Gov. Code §65913.4(a)(6), no demolition of a listed historic structure, tribal consultation, and a Phase I environmental assessment |
| §15300.2 exceptions | Apply | Written for categorical exemptions; the statute sets its own conditions |
| Notice of Exemption | Optional; starts the 35-day period | The lead agency “shall file” one with the Governor's Office of Land Use and Climate Innovation and the county clerk |
More on the statute in the AB 130 guide.
A housing project that misses one condition
Public Resources Code §21080.1(b) covers a housing development project that would be exempt under a statutory exemption or Classes 1 to 5, 12, 15, 20, 27, 30 or 32 “but for a single condition.” Review is then limited to effects “caused solely by that single condition,” and an EIR need not discuss alternatives or growth-inducing impacts. A “condition” is “a physical or regulatory feature of the project or its setting or an effect upon the environment caused by the project.” It doesn't apply to projects not similar in kind to the exempt class, projects that miss two or more conditions, projects with a distribution center or oil and gas infrastructure, natural and protected lands, or builder's remedy sites over four acres.
A filled-in checklist
An illustrative project, not a real application: a 48-unit apartment building on a 1.2-acre former used-car lot inside city limits, on land designated and zoned for multifamily housing.
| Check | What the file shows | Status |
|---|---|---|
| (a) Consistency | Designation and zone allow the density; plans meet height, setback and parking standards; consistency table done | Met |
| (b) Location | Inside city limits; 1.2 acres; retail on two sides, apartments on a third, offices across the street; aerial photos attached | Met |
| (c) Habitat | Fully paved lot; biologist's memo finds no habitat and no species records on site | Met |
| (d) Traffic | Within half a mile of an existing major transit stop, so presumed less than significant | Met |
| (d) Noise, air, water | Construction noise and air quality studies under way; stormwater treatment plan drafted | Check |
| (e) Services | Water and sewer will-serve letters on file | Met |
| Exceptions | Cortese list, state scenic highways and historical resources checked; a former car lot may need a hazardous materials review | Check |
If a study shows a significant noise effect, Class 32 fails; because this is a housing project, §21080.1(b) could limit review to that single condition, and the project could also be tested against §21080.66.
Getting the finding drafted
ePlan's CEQA Exemption Finder lists Class 32 among its choices, checks the Cortese list, listed historical resources, state scenic highways and species records, and drafts a Notice of Exemption and an exemption memo. The draft is free to read and $49 to download as Word. It is an unsigned starting point, not legal advice, and it can't produce the traffic, noise, air or water studies condition (d) depends on. The lead agency decides whether the exemption applies.
