Historic Preservation Overlay Zone

Recognizing the need to identify and protect neighborhoods with distinct architectural and cultural resources, the City has developed an expansive program of Historic Preservation Overlay Zones (HPOZs). HPOZs, commonly known as historic districts, provide for review of proposed exterior alterations and additions to historic properties within designated districts. The City Council adopted the ordinance enabling the creation of HPOZs in 1979; Angelino Heights became Los Angeles’ first HPOZ in 1983. Today, the City of Los Angeles has 29 designated HPOZs, with many more under consideration (Proposed HPOZs). HPOZ areas range in size from neighborhoods of approximately 50 parcels to more than 3,000 properties. While most districts are primarily residential, many have a mix of single-family and multi-family housing, and some include commercial and industrial properties. HPOZs are established and administered by the Los Angeles City Planning Department (in concert with the City Council). Individual buildings in an HPOZ need not be of landmark quality on their own: it is the collection of a cohesive, unique, and intact collection of historic resources that qualifies a neighborhood for HPOZ status.

认识到识别并保护具有独特建筑与文化资源的社区的必要性，洛杉矶市制定了一项涵盖广泛的历史保护叠加区（Historic Preservation Overlay Zones，HPOZs）计划。HPOZs通常被称为历史街区，旨在对指定区域内历史建筑的拟议外部改造及扩建进行审查。洛杉矶市议会于1979年通过了允许设立HPOZs的法令；安吉莉诺高地（Angelino Heights）于1983年成为洛杉矶首个HPOZ。如今，洛杉矶市已有29个已指定的HPOZs，另有更多区域正在审议中（拟议HPOZs）。HPOZ区域的规模各异，从约50个地块的社区到超过3000处房产的区域不等。虽然大多数区域以住宅为主，但许多区域混合了单户和多户住宅，部分区域还包含商业及工业房产。HPOZs由洛杉矶市规划局（与市议会协同）设立并管理。HPOZ内的单个建筑本身无需具备地标品质：正是具有凝聚力、独特性且保存完整的历史资源集合，使一个社区具备获得HPOZ地位的资格。
