Summary

Palmdale runs a streamlined, expedited review track for small residential rooftop solar under PMC § 8.05.030, covering systems up to 10 kilowatts AC or 30 kilowatts thermal on a duplex or single-family home that meet a Building Official checklist tied to the state Solar Permitting Guidebook.

Streamlined Process. Consistent with Government Code Section 65850.5 and Civil Code Section 714, the Building Official shall implement an expedited, streamlined permitting process for small residential solar systems and adopt a checklist of all requirements with which small rooftop solar energy systems shall comply in order to be eligible for expedited review.

Full Breakdown

030 directs the Building Official to implement an expedited, streamlined permitting process for "small residential solar systems" and to adopt a compliance checklist, which becomes binding on all applicants once approved by the Planning Commission by motion or resolution and published on the City's website. 020(B) defines a qualifying "small residential rooftop solar energy system" as one no larger than 10 kilowatts alternating current nameplate rating or 30 kilowatts thermal, installed on a duplex or single-family dwelling, conforming to state fire, structural and electrical codes, and not exceeding the maximum legal building height.

The checklist may reference the current California Solar Permitting Guidebook adopted by the Governor's Office of Planning and Research. 040(E) requires only a pre-inspection of roof penetrations and a single final inspection, done in a timely manner; a failed final inspection authorizes subsequent inspections. 010 authorizes the City to modify the state Guidebook standards for snow load and high wind. 020(A) as exceeding $1,000 over the specified cost or cutting efficiency by more than 10 percent, with the Building Official required to notify the Director of Economic and Community Development in writing of any such waiver and the reason for it.

Violations & Fines

There is no separate penalty specific to expedited review; a system that does not meet the checklist simply falls out of the expedited track and is processed under standard building permit review, subject to the same correction-notice and appeal procedures as any other building permit under PMC § 8.05.040.

Frequently Asked Questions

What size solar system qualifies for expedited review in Palmdale?
PMC § 8.05.020(B) caps eligibility at 10 kilowatts AC nameplate rating or 30 kilowatts thermal, installed on a duplex or single-family home that does not exceed the maximum legal building height and meets state fire, structural and electrical codes.
How many inspections does an expedited Palmdale solar permit require?
PMC § 8.05.040(E) requires a pre-inspection of the roof penetrations to confirm footings are properly installed, plus only one final inspection for eligible small residential systems; a failed final inspection allows further inspections.
Can Palmdale waive a solar rule that raises my system cost?
Yes. Under PMC § 8.05.050, if a requirement significantly increases system cost, defined as more than $1,000 over the original estimate, or cuts efficiency by over 10 percent, the Building Official can decline to enforce it and must notify the Director of Economic and Community Development in writing.
