Vacaville FAQ
Does Vacaville require native plants?
No outright mandate, but the Water Efficient Landscape Ordinance at VMC Section 14.27 limits high-water-use plants on covered projects, effectively favoring California natives and drought-tolerant species. Pure ornamental thirsty plants are constrained by the water-budget calculation.
Can I get a rebate for replacing my lawn?
Yes through the Solano County Water Agency lawn-conversion rebate. The converted area must be at least 50% covered by low-water, drought-tolerant, or California-native plants at maturity - high-water-use plants are excluded from the qualifying area.
When is the best time to plant California natives?
Fall, before the winter rains. Native plant sales by the California Native Plant Society and UC Davis Arboretum typically run October-November and are timed to align with the planting window.
Vallejo FAQ

Many states prohibit HOAs from banning xeriscaping or native plant gardens. Check your state laws and Vallejo ordinances.
Are there rebates for replacing my lawn?
