Encinitas Homes with ADU, Casita & Guest House

This page is your guide to Accessory Dwelling Units (ADUs) in Encinitas, CA. Here you’ll find live MLS listings, Coastal Zone ADU rules, and zoning insights for buyers and owners targeting casitas, guest houses and second units along this luxury coastal corridor.

Much of Encinitas lies in the Coastal Zone, which means Coastal Development Permits (CDPs), Design Review and neighborhood character all matter when planning a second unit — especially in areas like Leucadia and Cardiff-by-the-Sea.

Fun Fact: Encinitas is often called the “Flower Capital of the World” and includes unique zoning overlays in Leucadia and Cardiff that can impact lot size, density and where an ADU can realistically sit.

Investment Potential: Why Build or Buy an ADU in Encinitas?

Encinitas ADUs can capture elite coastal rental demand. Legal, high-finish ADUs and casitas near the beach or village can attract long-term tenants and premium rents.
Coastal scarcity amplifies the value of each legal second unit. In a low-supply coastal market, a permitted ADU or guest house can materially boost appraisal and resale.
State law preserves ADU rights even in Coastal Zone areas. Projects can still benefit from 4-foot side and rear setbacks, subject to CDP and design review.
Multi-gen and work-from-home lifestyles fit Encinitas perfectly. A detached casita can serve as a guest suite, office, studio or long-term rental while preserving privacy.
