What a Contractor's Building Permit History Tells You — and What It Doesn't
A contractor's website says what they'd like to build; their building permits say what they've actually built — inspected work, filed under their license number, with a date and a place. Read a permit record for five things: volume (how much of this kind of work), recency (is it still their business?), kinds of work (solar, batteries, roofing, panel upgrades), equipment (which brands appear in their permits) and where (the cities and ZIP codes they really work in — which can be far from the office address on their license). Then remember the gaps: permits only exist where a permit was pulled, only count where the portal is searchable, and say nothing about how the company treats customers. Every contractor profile in Cali-Graf, the free directory built by Cali Energy, a Los Angeles solar and roofing contractor, is built on that record.
Five things a permit record shows
| Read | What it tells you | A good sign | Worth a question |
|---|---|---|---|
| Volume | How much of this work they've done | Dozens or hundreds of jobs of your kind | Very few, for a company that advertises heavily |
| Recency | Whether it's still their line of work | Permits in the last few months | Nothing in years |
| Kinds of work | What they actually build | Solar and batteries, if you want both | Mostly a different trade |
| Equipment | Brands named in their permits | The panels and batteries you're considering | Brands you didn't expect |
| Where | The cities and ZIP codes of their permits | Recent permits in or near your ZIP code | All their work is far away |
Is this company local?
The office address on a contractor's license and the place it works can be very different. Some of the largest solar installers in Southern California hold licenses with offices in other states; a small local company may have an office in your city and permits all around it. Cali-Graf's profiles show both on purpose: the office city at the top, and Where they work further down — the jurisdictions and top ZIP codes where the company's permits were issued, labeled not the office address. If you care about who'll answer the phone when something needs fixing, the second is what matters: recent permits near you mean crews who know your city's inspectors and your utility.
How Cali-Graf builds the record
Cali-Graf matches building permits to contractors by the CSLB license number on the permit — 748,597 permits as of October 2026. A profile's Work history shows permits by year, the kinds of work as bars (solar, battery storage, roofing, HVAC, panel upgrades, EV chargers and more) and the most recent permits with the date, kind of work, jurisdiction and ZIP code — never a homeowner's name or street address. Equipment they install counts the products named by model in the permits.
| Portal | Covered |
|---|---|
| City of Los Angeles | April 2006 – October 2026 |
| City of Anaheim | November 1999 – September 2026 |
| City of Huntington Beach | January 2024 – October 2026 |
| City of Palmdale | June 2023 – October 2026 |
| City of Rancho Cucamonga | March 2024 – October 2026 |
| San Diego County | October 2024 – October 2026 |
| City of Chula Vista | March 2026 – October 2026 |

Three rules keep the record accurate. Permits are tied to a contractor by the license number on the permit, not by name, so two companies with similar names don't get mixed up. License facts come from the CSLB license master file — as of October 2026, the copy dated October 4, 2026 — so a status can lag the live CSLB record by days; each profile shows when it was last checked. And what a company says about itself on its website is shown only after the site is confirmed to belong to the license, and is labeled as the company's own claim. Mistakes — a permit matched to the wrong company, for example — can be reported and are checked against the source.
What a permit record can't tell you
- Work in cities whose portals aren't loaded. A contractor busy in Pasadena or Glendale may look quiet here. Ask where they've worked recently, and check that city's records if it matters.
- Work under someone else's license. On larger jobs the permit may name a general contractor or a partner, not the company you're talking to.
- Unpermitted work. By definition, it isn't in the record — which is also why a permit record is worth more than a photo gallery.
- Quality and service. A permit shows the work passed inspection, not whether the crew was on time or the company answered calls. Reviews and references still matter; see best-reviewed solar companies in Los Angeles.
A thin record isn't automatically a bad sign — a new company has to start somewhere — but it is a reason to ask for references and to check the license carefully; see how to check a solar contractor's license and permits.
