Zoning & HOA Considerations
Standby generators are subject to setback requirements, typically 5 feet from any building opening (NFPA 37) and 3+ feet from property lines. Some jurisdictions require site plan review showing generator placement. Noise ordinances (typically 55-65 dBA daytime, 45-55 dBA nighttime) may affect placement.
If you live in an HOA community: hOAs often restrict generator placement, enclosures, and visibility. Some prohibit generators outright or require sound enclosures. Generators near pools, patios, or bedroom windows face the most scrutiny. Check CC&Rs before purchasing, a $6,000 generator that violates HOA rules is a major problem.
