Solar Permits in Lake Mary, FL — Complete Guide
Last updated: July 13, 2026 by Goldin Solar permitting team
The City of Lake Mary is a Seminole County municipality just south of Sanford and north of Longwood, anchored by the I-4 corporate corridor (Lake Mary Boulevard). Lake Mary sits in Wind Zone 140-150 mph under FBC 8th Edition (2023). The city is dominated by master-planned residential — Heathrow (gated, golf), Magnolia Plantation, Timacuan, Greenwood Lakes, and Lake Mary Woods. Lake Mary building permitting is administered by the City of Lake Mary Building Department — distinct from unincorporated Seminole County and the City of Sanford.
Lake Mary-specific solar permit considerations
- Wind Zone 140-150 mph design. Standard inland structural calcs. PE-sealed structural required.
- Heavy master-planned ARC density. Heathrow is the largest single gated community in Lake Mary and has rigorous ARC review. Other master-planned communities (Magnolia Plantation, Timacuan) also have ARCs. ARC review is the dominant timeline variable.
- F.S. §163.04 cover-letter pattern. Standard ARC submission package + tile-color-matched module proposal where ARC-aesthetic concerns emerge.
- No HVHZ.
- No salt-air exposure. Inland; standard fasteners.
- Tree canopy. Mature Magnolia/Timacuan canopy can constrain shading on some lots — site-by-site shade analysis pre-quote.
Utility coordination
Duke Energy is the dominant utility for Lake Mary. Duke net metering is governed by the FL PSC.
