Title 9Chapter 5 — CITYWIDE USE AND DEVELOPMENT REGULATIONS

Article 10 — Nonconforming Uses And Structures

Emeryville Zoning Code · 2026-06 edition · ingested 2026-07-06 · Emeryville

9-5.1001. Purpose.

This article establishes regulations for nonconforming uses and structures. The purpose of these provisions is to regulate uses of land and structures that were legal before the adoption or amendment of these planning regulations, but which no longer comply. The intent of this article is to permit nonconforming uses to continue until they are removed or required to be terminated, but not to encourage their survival. More specifically, it is the intent of this article to distinguish between incompatible nonconforming uses that are detrimental to public health, safety, and general welfare, and nonconforming uses that are economically productive and compatible with surrounding development despite being inconsistent with the use regulations of these planning regulations.

(Sec. 2 (Exh. A) (part), Ord. 13-001, eff. Mar. 7, 2013)

9-5.1002. Applicability.

The provisions of this article apply to uses that have become nonconforming by adoption of these planning regulations, uses that were previously nonconforming and remain nonconforming under these planning regulations, and uses that become nonconforming due to subsequent amendments to these planning regulations, except as provided in Section 9-5.1003. (Sec. 2 (Exh. A) (part), Ord. 13-001, eff. Mar. 7, 2013)

9-5.1003. Exceptions.

The provisions of this article do not apply in the following situations:

  • (a) Signs. Nonconforming signs shall be subject to the provisions of Section 9-5.1614.

  • (b) Residential Uses. Any residential use, lot, or structure that was legally established prior to the adoption of these planning regulations and that has been continuously maintained in residential use in compliance with the requirements of all applicable codes is deemed to be a conforming use, lot, or structure. However, any enlargement or replacement of such use shall conform to these planning regulations.

  • (c) General Manufacturing Uses. Any General Manufacturing use, lot, or structure in the INL Light Industrial zone that was legally established prior to the adoption of these planning regulations and that has been continuously maintained in compliance with the requirements of all applicable codes is deemed to be a conforming use, lot, or structure. However, any enlargement or total replacement of such use shall conform to these planning regulations.

  • (d) Public Uses. Provided that there is no change of use, nothing in this article shall require the termination, discontinuance, or removal of a public use or a public utility or to prevent the expansion, modernization, replacement, repair, maintenance, alteration, reconstruction, or rebuilding and continuation of public use or utility buildings, structures, equipment, and facilities.

  • (e) Planned Unit Developments. Planned unit developments approved prior to the adoption of these planning regulations, as listed in Section 9-3.310, are subject to the use and development regulations stipulated in the various ordinances establishing the PUDs. If the ordinance for a PUD does not address a particular issue, these planning regulations shall

apply to that issue. Any modifications to such PUDs shall be subject to the provisions of these planning regulations.

  • (f) Other Planning Entitlements. Any use allowed under a planning entitlement, including but not limited to a conditional use permit, design review permit, or variance, that was approved prior to the adoption of these planning regulations and that has not expired, is deemed to be a conforming use and is subject to any conditions included in its approval, except that off-street parking may be reduced or eliminated upon the granting of a minor conditional use permit pursuant to Section 9-4.403(a)(1)(a). If such a use is not permitted by these planning regulations, it may be expanded pursuant to Section 9-5.1011, except those uses that are deemed incompatible pursuant to Section 9-5.1007. Other modifications to such a use beyond what was originally approved shall be subject to the provisions of these planning regulations.

  • (g) Structures under Construction. Nothing contained in this article shall be deemed to require any change in the plans, construction, or designated use of any building or structure for which a building permit has properly been issued prior to the adoption of these planning regulations.

9-5.1004. Nonconforming Uses as Distinguished from Illegal Uses.

  • (a) Nonconforming Use. A nonconforming use is any use of land, use of structure, lot, or structure that was legally established prior to the adoption of these planning regulations, but which does not conform to the provisions of these planning regulations. Nonconforming uses may be continued, maintained, repaired, altered, substituted for another nonconforming use, expanded, restored or reestablished only in conformance with the requirements of this article.

    • (1) Nonconforming uses include:

      • a. Uses made nonconforming by the addition of a standard or requirement in these planning regulations that was not previously required for such use; and

      • b. Uses that were previously permitted by right and are subject to a discretionary permit under the requirements of these planning regulations.

    • (2) A nonconformity may result from any inconsistency with the requirements of these planning regulations, including but not limited to location, density, floor area ratio (FAR), height, setback, usable open space, parking, or performance standards or the lack of a conditional use permit, variance, or other required planning entitlement.

    • (3) A use or structure shall not be deemed nonconforming solely because it does not conform with the applicable design standards for parking lots and structures pursuant to Section 9-4.406, allowed projections above the top of buildings pursuant to Section 9-4.202(c), or restrictions on features allowed in required yards pursuant to Section 9-4.301(e), or because of other minor deviations from the requirements of these planning regulations.

  • (b) Illegal Use. An illegal use is a use of land, use of structure, lot, or structure that was not legally established under the regulations that were applicable at the time it was established,

Uses of special concern, as listed in Section 9-2.701, that are prohibited in the zoning district in which they are located, as indicated in Article 2 of Chapter 3, are hereby declared to be incompatible uses and may be continued but shall not be expanded, substituted for another nonconforming use, or reestablished if abandoned for more than ninety (90) days. An incompatible use may be substituted with a nonconforming use that is not an incompatible use pursuant to the requirements of Section 9-5.1010(d).

(Sec. 2 (Exh. A) (part), Ord. 13-001, eff. Mar. 7, 2013)

A nonconforming use may be changed to a conforming use or substituted with another nonconforming use subject to the requirements of this section. These requirements shall not apply to a change of ownership, tenancy, or management where there is no change in use type and the use is not expanded.

  • (a) Change from Nonconforming to Permitted Use. Any nonconforming use may be changed to a use that is permitted by right in the zoning district in which it is located and that complies with all applicable standards for such use. Any such change in use terminates the right of the previous nonconforming use to continue to exist, and it may not be reestablished.

  • (b) Change from Nonconforming to Conditionally Permitted Use. Any nonconforming use may be changed to a use that is conditionally permitted in the zoning district in which it is located, subject to the approval of a conditional use permit pursuant to Article 5 of Chapter 7 and any other applicable findings and standards for the new use. Any such change in use terminates the right of the previous nonconforming use to continue to exist, and it may not be reestablished.
