Temecula FAQ
Does my pool count toward coverage?
In-ground pools typically do not count toward lot coverage but may count toward impervious surface limits in Hillside zones — covered pool houses do count.
Are ADUs counted in coverage?
State law (Gov Code §65852.2) exempts ADUs up to 800 sq ft from local coverage limits if those limits would prohibit the ADU.
What about a covered patio?
Permanent solid-roof patios count toward coverage; open lattice patios and shade structures generally do not, but verify with Planning before permitting.
