SB 484 California Senate · 2025-2026 Regular Session

Coastal resources: coastal development permits: infill area categorical exclusion.

Summary
Existing law, the California Coastal Act of 1976, among other things, requires anyone wishing to perform or undertake any development in the coastal zone, except as specified, in addition to obtaining any other permit required by law from any local government or from any state, regional, or local agency, to obtain a coastal development permit from the California Coastal Commission or a local government, as provided. The act provides that a coastal development permit is not required for specified types of development in specified areas, as provided. Existing law provides that a coastal development permit is not required for any category of development, or any category of development within a specified geographic area, if the commission, after a public hearing, and by a 23 vote of its appointed members, finds that there is no potential for any significant adverse effect, as specified, on coastal resources or on public access to, or along, the coast and, where the exclusion precedes certification of the applicable local coastal program, that the exclusion will not impair the ability of local government to prepare a local coastal program. Existing regulation, before a categorical exclusion becomes effective, requires specified things to occur, including that the public agency issuing the permit accepts and agrees to the terms and conditions to which the categorical exclusion has been made subject. This bill would require the commission, in consultation with the Department of Housing and Community Development, by July 1, 2027, to identify, based on specified considerations, infill areas within at least 3 local jurisdictions that do not have a certified local coastal program for a categorical exclusion from the coastal development permitting requirement. Specifically, until June 30, 2037, if a development in one of those identified infill areas is a residential housing project comprised only of units that are deed restricted for persons of very low, low, or moderate income, as specified, this bill would categorically exclude the development from that requirement. The bill would exempt the categorically excluded infill areas from the above-described regulation. The bill would require, before commencing development, a proponent of the development to request from the commission, and for the commission to issue, a notice of exclusion. This bill would require the commission, on or before August 1, 2027, to post on its internet website clearly defined maps of the categorical exclusion areas. The bill would also require the commission, on or before January 1, 2035, to report to the Legislature the number of projects that were constructed or are currently under construction pursuant to this categorical exclusion.

MODERATE
The Assembly amended SB 484 to adjust how the Coastal Commission selects jurisdictions and identifies specific infill areas for the coastal development permit categorical exclusion for affordable housing. The criteria for selecting jurisdictions became less rigid (from 'consider all' to 'do both'), while the criteria for identifying specific areas within those jurisdictions became more comprehensive, adding requirements to consider housing element inventories and avoid sea level rise sites. A new requirement was added for the commission to post maps of exclusion areas on its website by August 1, 2027.
REQUIREMENT

In subdivision (c)(1), the standard for selecting jurisdictions changed from 'shall consider all of the following' to 'shall do both of the following,' potentially making jurisdiction selection less stringent. However, four criteria are still listed, creating ambiguity about how many must be satisfied.

In subdivision (c)(2), the standard for identifying specific exclusion areas changed from 'shall do both of the following' to 'shall do all of the following,' and two new criteria were added: (C) consider each jurisdiction's housing element site inventory, and (D) avoid sites projected to be impacted by sea level rise and associated coastal hazards.

New subdivision (f) requires the commission to post clearly defined maps of the categorical exclusion areas on its internet website on or before August 1, 2027, adding a transparency and public access requirement not present in the Senate version.

TECHNICAL

Subdivision (a)(1) was simplified from 'shall be categorically excluded from the permit requirements of this chapter and shall not require the issuance of a coastal development permit' to 'shall be categorically excluded from the requirement to obtain a coastal development permit,' removing redundant language.
