Coverage depth varies by state. California is by far our deepest, with 288 published city guides. Where we don't yet have enough verified information to publish a full guide, we say so rather than guessing. See our Methodology for exactly how a page earns "published" status.
What makes a GridPermit guide different
- Every fact is source-linked. Permit fees, required documents, utility rules: each one traces to an official government or utility page, not a summary of a summary.
- Every fact is dated. Guides show when they were last verified, so you know how current the information is.
- We say what we don't know. A city with incomplete research is marked as limited coverage, not silently filled in.
- After the facts, one clear next step. Guides link to a real installer marketplace if you're ready to compare quotes, never before you've read the actual permit requirements.
