Fee schedule
Solar PV / Alternative Energy Permit Fee — valuation-based (standard Building Permit Fee table)VERIFIED — unlike Denver's published flat $50 PV fee, Lakewood has no Alternative-Energy-specific line in its Flat Fee Permits table, so Solar PV/thermal falls under the fee schedule's own governing rule: 'With the exception of the fees listed in the FLAT FEE PERMITS table, all building permit fees are based on total valuation including labor and materials.' Confirmed by re-fetching the full 2-page fee schedule PDF (Playwright browser-fetch past the Akamai/edgesuite WAF, then pdftotext -layout) and reading it in full — Alternative Energy/Solar is absent from the Flat Fee list (fence, water heater, furnace, A/C, evaporative cooler, siding, reroof, temp trailer, demolition, move-and-set) and absent from any separate solar fee table. A companion Electrical permit and inspection is also required for grid interconnection per 2023 NEC Article 690, separately fee-bearing on the same valuation-based schedule.
Assessed on the solar installation's valuation (labor + materials for panels, racking, inverter, and grid-interconnection electrical work) using Lakewood's standard Building Permit Fee table — $26.00 minimum (valuation $1.00-$500.00) scaling up to $5,570.15 for the first $1,000,000.00 plus $3.45 per additional $1,000.00

Tips
- Lakewood's Alternative Energy permit type explicitly separates 'New' installs from 'Remove and Reset' (for reroofs/repairs) — apply for the correct subtype in eTRAKiT to avoid delays.
- Structural calculations must account for Lakewood's 30 psf minimum roof snow/live load and Seismic Design Category B (residential) per the City's Codes and Loads handout.
- Unlike Denver, which publishes a flat $50 solar PV fee, Lakewood has no Alternative-Energy line in its Flat Fee Permits table — solar/thermal is billed on the standard valuation-based Building Permit Fee schedule instead, plus a separate Electrical permit for grid interconnection.
- No Lakewood-specific SolarAPP+ (instant online solar permitting) reference was found on the City's own Building and Construction Permits page as of this verification — do not assume SolarAPP+ applies here without confirming directly with the Permit Counter (303-987-7500).
