Interactive Parcelscope map visualizes Los Angeles’ surviving buildings by construction year from 1880 to 2026

Parcelscope’s Los Angeles visualization shows one box for every building still standing today, appearing in the year it was built. The map uses LARIAC 2020 building outlines and LA County Assessor data, with filters for decade, height, footprint, and type.

The project highlights how urban history can be explored through parcel-level data rather than static maps or timelines. Because demolished structures are excluded, it offers a view of the city’s surviving built environment, useful for spotting development waves, preservation gaps, and density trends.
