"It's tiresome to not have a single permit information database. We'd spend so much time pulling bits of information from all the county assessors, with no way to quickly tell what the AHJ and regulations were for a given project." — Aaron Casillas, Titan Solar Power

Frequently asked questions

For each of the 3,100+ US county building permit offices: office name, physical address, phone number, email address, website URL, submission method (online portal, in-person, email, or mail), permit fee information, and any notable requirements or turnaround times. Data is exported as CSV and JSON.
SunSpec tells you which AHJ governs a given address — the assignment layer. AHJdata gives you the operational layer: who to call, what it costs, how to submit, and what format they accept. They answer different questions. SunSpec tells you "this address is governed by Harris County." We tell you Harris County's permit office phone number, email, fee schedule, and that they accept applications through their online portal.
Annual subscribers receive quarterly data refreshes with a detailed changelog showing what changed — updated phone numbers, new staff contacts, revised fee schedules, changed submission requirements. Permit office contacts have approximately 30% annual turnover, so quarterly refreshes keep the data reliable. One-time purchases receive a point-in-time snapshot.
30-day money-back guarantee on all plans, no questions asked. If the data doesn't save you time, we'll refund you in full.
Solar installers, general contractors, permit coordinators, permit software companies, and anyone who regularly interacts with county building permit offices across multiple jurisdictions. If you've ever spent 30 minutes trying to find the right phone number for a county permit office, this is for you.
