Denver Community Planning and Development uses NREL's SolarApp+ for instant online permits for code-compliant rooftop solar PV. Colorado HB21-1255 caps fees, requires 7-business-day plan review, and bars HOA blocks, accelerating residential adoption.
Denver Community Planning and Development (CPD) adopted SolarApp+ in 2023 to issue same-day permits for compliant residential rooftop photovoltaic systems on one- and two-family homes. Installers complete an online checklist; if the design passes automated code checks, the permit issues immediately and inspection is scheduled. Colorado HB21-1255 caps the residential solar permit fee at $500 ($1,000 commercial), requires permit decisions within seven business days, prohibits ad-hoc engineering charges, and allows online submittal. Combined with Xcel Energy net-metering and the federal 30% Investment Tax Credit, Denver's process is among the fastest in the Rocky Mountain region. Battery storage and complex roof designs still need plan review by CPD staff.
Installing solar without a Denver permit voids inspections, can force teardown, and triggers CPD stop-work orders with fines up to $999 per day under DRMC §10-15. Xcel will refuse interconnection without a final electrical inspection card.
