06 / Questions
Still curious? Good.
Straight answers to what every California homeowner asks before building.
Talk to a SpecialistIt's an investment that pays for itself. With our $0 out-of-pocket financing, most homeowners build using their property's equity — and rental income of $1,500–$3,500+/month typically covers the financing payment with margin left over.
Timelines vary by project type and city. Generally, permitting takes 2–4 months and construction takes 4–8 months after permit approval. We handle every step and keep you updated throughout, so your involvement stays light.
Completely. California ADU law is homeowner-friendly, but each city applies it differently. We prepare the plans, pull the permits, respond to plan-check comments, and manage inspections through final sign-off.
Through our financing partners, qualified homeowners leverage existing home equity to fund the entire build — no cash down. You start paying only once the project funds, and rental income typically offsets the payment.
A well-built ADU typically adds $150,000–$300,000+ to a California property's value — often more in high-demand areas — while simultaneously generating monthly rental income.
