§ 8174-6.2.2. Improvements to existing single-family dwellings.

(a)

Pursuant to Section 30610(a) of the Public Resources Code, improvements to existing, legally-permitted single-family dwellings are exempt from coastal development permit requirements, with the exception of those developments listed in subsection (c).

(b)

For the purposes of this Section, the following are considered part of single-family dwellings:

(1)

All fixtures and other structures directly attached to a dwelling;

(2)

Structures on the property normally associated with a single-family residence, such as garages, swimming pools, fences, and storage sheds; but not including guest houses or self-contained residential units; and

(3)

Landscaping on the lot.

(c)

Pursuant to Section 13250 of Title 14 of the California Code of Regulations, the following improvements to existing single-family dwellings require a coastal development permit because they involve a risk of adverse environmental effects:

(1)

Improvements to a single-family structure if the structure or improvement is located: on a beach, in a wetland, seaward of the mean high tide line, in ESHA, in an area designated as highly scenic in a certified land use plan, or within fifty (50) feet of the edge of a coastal bluff;

(2)

Any significant alteration of land forms including removal or placement of vegetation, on a beach, wetland, or sand dune, or within 50 feet of the edge of a coastal bluff, or in ESHAs;

(3)

The expansion or construction of water wells or septic systems;

(4)

On property not included in subsection (c)(1) that is located between the sea and the first public road paralleling the sea or within three hundred (300) feet of the inland extent of any beach or of the mean high tide of the sea where there is no beach, whichever is the greater distance, or in significant scenic resources areas as designated by the commission or regional commission, improvement that would result in an increase of ten (10) percent or more of internal floor area of an existing structure or an additional improvement of ten (10) percent or less where an improvement to the structure had previously been undertaken pursuant to Public Resources Code Section 30610(a), increase in height by more than ten (10) percent of an existing structure and/or any significant non-attached structure such as garages, fences, shoreline protective works or docks;

(5)

In areas which the commission or a regional commission has previously declared by resolution after public hearing to have a critically short water supply that must be maintained for the protection of coastal resources or public recreational use, the construction of any specified major water using development not essential to residential use including but not limited to swimming pools, or the construction or extension of any landscaping irrigation system;

(6)

Any improvement to a single-family residence where the development permit issued for the original structure by the commission, regional commission, or local government indicated that any future improvements would require a development permit.
