To limit the number and extent of nonconforming uses which conflict with the provisions of this title by restricting their enlargement, their reestablishment after abandonment, and their alteration or restoration after destruction of the structures they occupy;

To eventually eliminate nonconforming uses or provide for their alteration to conform with the provisions of this title;

To allow structural improvements and minor additions to structures containing nonconforming uses to be considered in order to prevent these structures from becoming blighted and having detrimental impacts on the surrounding neighborhood, provided that such improvements or additions shall not adversely impact surrounding property, that there is no increase in the degree of nonconformity with respect to the development standards for the zone in which the property is located, and that the life of the nonconforming structure is not substantially increased;

To allow for the reconstruction of existing residential uses that are involuntarily destroyed in residential zones;

To allow for additions to nonconforming structures containing conforming uses, provided that there is no increase in the degree of nonconformity with respect to the development standards for the zone in which the property is located;

To eventually eliminate billboards which have a blighting impact on the City's commercial corridors.

Continuation or replacement of a nonconforming use. A nonconforming use may continue provided there are no structural alterations to the structure in which the use is located except for those required by the Chief Building Official, and except those approved pursuant to subsection (b) of this section. An existing nonconforming use may be changed to another nonconforming use, providing:

Structural alterations and minor additions to a nonconforming use. Structural alterations or minor additions to a nonconforming use may be approved subject to Planning Commission Design Review pursuant to Section 10-2.2502, and subject to the following criteria:

Adding additional uses. While a nonconforming use exists on any lot, no additional use may be established thereon even though such other use would otherwise be a permitted use.

Discontinuance of uses. A nonconforming use which has been suspended or discontinued for a continuous period of at least two years shall automatically expire and may not be renewed, nor replaced, by any other use not permitted within the zone. A nonconforming use which has been changed to a conforming use for a continuous period of six months or more shall not be re-established, and the use of the structure or site thereafter shall be in conformity with the land use regulations for the zone in which it is located.

Re-establishment of uses in structures partially destroyed. A nonconforming use in a structure destroyed due to an involuntary event to the extent of 50% or more of its square footage at the time of its partial destruction may not be re-established and any new structure shall conform to all the requirements of City laws upon reconstruction.

Continuation of nonconforming structure. Where a use is conforming but the structure is nonconforming because it does not comply with the development standards for the zone in which it is located, such structure may continue and may be structurally altered.

Floor area additions. Any addition of floor area to the structure shall meet the full requirements for the zone in which it is located, and also shall not increase the degree of nonconformity of the structure as a whole with regard to density, building height, floor area ratio, or off-street parking. Further provided, floor area additions to existing residential units may be permitted without fully complying with the parking requirements only if the Community Development Director determines that: (1) it is physically impossible to locate the required parking on site without relocating or demolishing all or a portion of the existing residential structure; or (2) the cumulative economic value of the currently proposed addition and previous additions made subsequent to March 12, 1975 are less than the value of the otherwise required garage.

Reconstruction of nonconforming structures partially destroyed. A nonconforming structure destroyed to the extent of 50% or more of its square footage at the time of its partial destruction shall conform to all the requirements of City laws upon reconstruction, except as follows:

Nonconforming signs. Nonconforming signs shall be regulated subject to Section 10-2.1816.

Nonconforming billboards. Nonconforming billboards shall be removed upon the occurrence of any of the following:

Agreements to remove existing billboards in exchange for new billboards facing the San Diego Freeway. Notwithstanding subsection (b) of this section, the City Council may enter into agreements to remove existing billboards within the City of Redondo Beach in return for permitting new billboards at locations facing the San Diego Freeway, provided there is a net reduction in total billboards, and subject to approval by CALTRANS. Such billboards may be permitted to exceed the height standards of the zone in which they are located. No sign face shall exceed 700 square feet in area (excluding the apron below the sign face).
