Solar permits in Hacienda Heights
How to install a solar in Hacienda Heights: permit pathway through LA County Public Works (Building & Safety), drawings required, local watch-outs, and a free address-level wizard for your Hacienda Heights lot.
Hacienda Heights context
Hacienda Heights sits in unincorporated LA County despite being surrounded by the cities of Industry, La Puente, and Whittier. Permits run through LA County DPW Building & Safety at the Alhambra office via the EPIC-LA online portal — not through any city department. ADU rules follow the state baseline (Gov Code §65852.2) implemented through LA County Code Title 22.140. Northern hillside parcels (the Puente Hills foothills) face hillside grading + geotech review on top of standard ADU rules.

Local quirks
Not a city — LA County DPW handles permits, not LADBS
Hacienda Heights residents sometimes confuse jurisdiction with neighboring Industry or Whittier. All Hacienda Heights permits run through LA County Public Works Building & Safety at the Alhambra office.
Hillside grading review on Puente Hills foothills
Lots along the Puente Hills foothills slope significantly and trigger LA County hillside grading review. Geotech reports typically required.
