Reducing Red Tape to Slash Rooftop Solar Costs — Episode 272
Brief
Elizabeth Ridlington (associate director and senior policy analyst, Frontier Group) joined host John Farrell (ILSR) in April 2026 to present Frontier Group’s solar permitting scorecard and to explain why streamlined permitting and inspections matter for rooftop solar adoption. Ridlington framed the work around two drivers: the need for much more rooftop solar (clean generation, reduced long‑distance transmission, and resilience when paired with batteries) and the fact that permitting and inspection processes currently add substantial cost and uncertainty—often 20–33% of project cost—making projects more expensive and causing installers and customers to abandon projects.
The conversation moved from installer anecdotes to concrete policy criteria. Ridlington described the “hot mess” of fragmented local rules: multiple unconnected online portals, in‑person application requirements, sequential multi‑department reviews, inconsistent code interpretations even within the same office, and long inspection windows that force technicians to wait on site. She cited examples: a Mesquite, TX median approval of three business days but a 10% tail of five weeks or more; an estimated 25% cancellation rate for Texas projects between application and permit; and installers who raise prices ~10% on average to cover permitting headaches. The scorecard evaluated statewide policies that reduce friction: enabling instant permitting (SolarAPP or Symbium), funding for jurisdictions, statewide or uniform building codes, limits on HOA restrictions (cost/efficiency caps or dollar caps), prohibiting aesthetic review in permit decisions (California and pending Maryland), remote or third‑party inspections (allowed in Delaware, Florida, Georgia, Utah), fee caps, and clear treatment of third‑party ownership (leases/PPAs) so they are not regulated as utilities.
Results: California and Texas scored best (B’s) because both enable near‑instant permitting via different means (automated state/local portals in CA; third‑party reviewers/inspectors and instant permitting options in TX); New Jersey and Colorado scored C’s; most states scored D/F. Ridlington and Farrell agreed that these reforms are low‑risk, high‑reward: they preserve health and safety while lowering costs, increasing competition, and speeding deployment. The episode closes with Ridlington’s intent to repeat the scorecard in two years and both speakers noting that streamlined permitting may help narrow the U.S.–international cost gap and drive far greater rooftop solar adoption.
Why it matters
Permitting and inspection can add roughly one-fifth to one-third (20–33%) to the cost of a rooftop solar installation, and Frontier Group’s scorecard work motivated by that price drag (Elizabeth Ridlington, April 2026).
Key details
- Frontier Group found wide procedural variation: Mesquite, Texas median permit approval is 3 business days but 10% of permits take five weeks or more; in Texas an estimated 25% of planned solar projects were canceled between permit application and issuance (Ridlington, citing installer interviews and data).
- A national installer survey found firms commonly raise prices to cover permitting friction—installers who increase prices do so by about 10% on average—and some firms keep proprietary manuals on navigating city-by-city rules (Ridlington).
- Frontier Group’s permitting scorecard (released March 2026) graded states: California and Texas earned B’s, New Jersey and Colorado C’s, and most other states received D’s or F’s — key differentiator: ability to use instant permitting or third-party permit reviewers (Ridlington).
- Policy levers identified as most effective: instant permitting software (DOE/SolarAPP or private tools like Symbium), state-level uniform building codes, caps on HOA interference (e.g., limits of 5–10% on cost/efficiency impacts or California’s $1,000 cap), remote or third‑party inspections, and limits on fee structures (Ridlington).
- Practical examples: Texas allows third‑party permit reviewers/inspectors; California prohibits permit review on non‑health/safety aesthetic grounds and supports automated permitting; Delaware, Florida, Georgia and Utah widely allow third‑party inspections (Ridlington).
