ADU Questions for Sunnyvale Homeowners
What makes Sunnyvale's ADU permitting process fast?
Sunnyvale uses a one-stop permit intake model where planning and building review happen in parallel rather than sequentially. Pre-application consultations are free and help applicants avoid common plan check comments that cause delays.
Does Sunnyvale have rent control that would affect an ADU?
Sunnyvale has a Rent Stabilization Ordinance for multi-unit rental housing, but newly constructed ADUs are generally exempt under state law. You can rent a new ADU at market rate without being subject to the rent stabilization cap.
What utility connection process should I expect in Sunnyvale?
Sunnyvale operates its own electric utility (Sunnyvale Electric), which can simplify the electrical service connection process compared to cities served by PG&E. Epic Modulars coordinates all utility connections as part of the installation process.

A 1-bedroom ADU in Sunnyvale typically rents for $2,400–$2,900/month depending on finishes, location, and proximity to transit. Our 1-bed/1-bath model (from $109K) consistently achieves strong rent in this range.
