Which activity does NOT require a Coastal Development Permit according to Section 30610?

Improvements to multi-family residences do not require a Coastal Development Permit according to Section 30610. This provision generally accommodates certain activities that are typically lower in impact or that fall within the category of ordinary maintenance or repairs. This is particularly relevant for residential improvements that do not significantly alter the existing use or substantial footprint of the property.

In contrast, maintenance dredging of navigation channels, repair of existing single-family dwellings, and replacement of structures destroyed by disasters generally involve activities that could have significant environmental impacts or alter the coastal land use. Therefore, they are subject to permitting processes to ensure they adhere to coastal regulations and protect public resources. This distinction highlights the balance achieved by the Coastal Act between allowing property owners to maintain and improve their properties while also safeguarding coastal environments.
