The Bottom Line

Compared to many U.S. cities, Moreno Valley gives residents more room on landscaping rules. 3 of the 8 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

These rules come from Moreno Valley's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
