Full Breakdown
5 by directing the building official to develop and publish an eligibility checklist on the city's website. 020), along with the required permit processing and inspection fees. 020 limits a "small residential rooftop solar energy system" to no larger than 10 kilowatts AC nameplate rating or 30 kilowatts thermal, installed on a single- or duplex-family dwelling, conforming to state fire, structural and electrical codes and Civil Code Section 714(c)(iii), and not exceeding the maximum legal building height set by the authority having jurisdiction. Systems meeting every checklist item are processed administratively rather than through discretionary land-use review, which is the core time savings the chapter creates for homeowners installing standard residential PV or thermal solar arrays.
Violations & Fines
There is no fine tied to this chapter itself; the consequence of noncompliance is procedural. A system that exceeds the 10 kW AC / 30 kW thermal cap, serves more than a duplex, or exceeds the applicable height limit falls outside the Section 15.45.020 definition and loses eligibility for the expedited checklist track, pushing the project into standard building permit review by the community development department's building official.
