Why Altadena construction is different

Altadena is unincorporated LA County, so permits run through County Building & Safety and County DPW — different staff, different workflow, different turnarounds than LA City. Hillside lots add the County Hillside Management Ordinance. A team with current Altadena experience knows which plan checkers to call and how to navigate the County's correction cycles.
