VertX is headquartered in West Covina, about 16 min from Glendora. We design, permit, and manage solar, Tesla Powerwall, and roofing projects for Glendora homeowners, with licensed crews and one company accountable for the whole job.
What's different in Glendora
Glendora is served by Southern California Edison. New solar systems go on SCE's net billing tariff (NEM 3.0), which pays very little for power you export, so we size every system to your actual usage and usually pair it with a battery so your evening hours run on your own stored power instead of the most expensive grid rates.
Building and electrical permits in Glendora are issued by the City of Glendora Building & Safety Division at 116 E. Foothill Boulevard. VertX prepares the plan set, files the application, and schedules the final inspection; you sign, we handle the rest.
Glendora has not switched on SolarAPP+ yet; its permit page still lists it as coming soon. Solar applications go through the city's Civic Access online portal (email submittals are no longer accepted), and the city's expedited small-solar ordinance requires eligible rooftop systems to be issued within three days. A Los Angeles County Fire notification form is required for solar and for any battery. The counter is open Monday through Friday.
Glendora has more Very High Fire Hazard Severity Zone acreage than any city we serve. CAL FIRE's 2025 map raised it to about 5,150 acres, a 27 percent increase, covering the entire foothill band north of Sierra Madre Avenue and, for the first time, the South Hills between the 210 and Route 66. The city adopted the map by ordinance in July 2025 and LA County Fire now sends defensible-space notices to affected parcels each February. The Colby Fire in January 2014 burned nearly 2,000 acres above town, destroyed five homes, and evacuated about 3,600 people. The foothills are in SCE's highest-tier fire-risk area, where Public Safety Power Shutoffs are planned for, which is why a Powerwall in north Glendora is a backup system first and a bill saver second.
Glendora has about 18,600 homes and roughly 68 percent are owner-occupied, with four in five single-family. The median home was built in 1964: a third of the stock is 1950s tract housing on composition shingle south of Foothill, and the foothill neighborhoods from Morgan Ranch to Gordon Highlands add larger 1970s to 1990s homes on tile. City design guidelines favor clay, concrete, or slate tile on new roofs, and the city has about 50 homeowner associations, many with architectural review.
Glendora has had a historic preservation ordinance since 1988, with 38 designated landmarks and one historic district. Exterior work on a designated property, including a reroof or rooftop solar, needs a certificate of appropriateness from the city, which carries no fee. We prepare it with the permit application.

Glendora questions
The foothills are in SCE's highest-tier high-fire-risk area, and SCE has run PSPS outreach to Glendora since 2020. We could not find a record of a specific de-energization inside the city, but the circuits north of Sierra Madre Avenue are the kind SCE shuts off in Santa Ana winds. A grid-tied solar system turns off during a shutoff by code; a Tesla Powerwall isolates the house and keeps it running on the panels through the day.
Glendora has not gone live with SolarAPP+ yet, so applications go through the city's Civic Access online portal, where the expedited small-solar ordinance requires eligible rooftop systems to be issued within three days. A Los Angeles County Fire notification form is part of the package, and any battery gets a fire review. VertX files everything through the portal and schedules the inspections.
If you are north of Sierra Madre Avenue, yes: the entire foothill band is Very High on CAL FIRE's 2025 map. The South Hills between the 210 and Route 66 became Very High for the first time in 2025. In those zones a reroof must be a Class A assembly with ember-resistant vents and other wildland-urban interface details, defensible-space rules apply, and shingles cannot be overlaid on the old roof. Most of the flats between Foothill and the 210 are outside the zones.
Not on every home, but the city's design guidelines favor clay, concrete, or slate tile, and many of the roughly 50 HOAs in Glendora have their own roof standards. Where tile is expected we install concrete tile, which also satisfies the Class A requirement in the fire zones. On homes where shingle is appropriate, GAF and Owens Corning Class A systems are the standard. We check the guideline and the HOA rule before we quote so the roof is approved the first time.
It is allowed. Glendora's preservation ordinance requires a certificate of appropriateness for exterior work on a designated landmark or in the historic district, including rooftop solar and reroofs, and the certificate has no fee. California's Solar Rights Act protects your right to install; the review is about placement and visibility. We lay out the array on the least visible slopes and submit the certificate with the permit.
