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

Escondido ADUs tap into strong local rental demand. Workforce tenants, multi-gen families and long-term renters all seek affordable second units inland.
Larger inland lots can support true detached casitas. Many parcels have room for 800–1,200 sq ft ADUs with private yards and separate entries.
State ADU law allows 4-foot side and rear setbacks. Reduced setbacks make it easier to place ADUs on sloped or irregular lots when fire and access rules are satisfied.
Multifamily parcels offer multi-ADU potential. Investors can often combine interior conversion ADUs with detached units under state rules.
