The Los Angeles City Council adopted the recommendations of the Cultural Heritage Commission and officially designated the William Mellenthin Birdhouse Apartments at 5922-5930 North Buffalo Avenue as a Historic-Cultural Monument. This Streamline Moderne–style apartment complex, built in 1949 and distinguished by its signature birdhouse rooflines and mid-century detailing, exemplifies post-war residential development in the Valley Glen neighborhood. Under Los Angeles Administrative Code Section 22.171.7, the designation requires future alterations or potential demolition to obtain a Certificate of Appropriateness, ensuring review and preservation of defining features such as stucco facades, wood casement windows, and the building’s overall massing. The protected status will guide maintenance and any sensitive restoration work, safeguarding the property’s architectural and cultural heritage.
