What will your ADU earn you?

With CALI ADU, a Signature Home costs between $219,000 and $459,000 — fixed, all-inclusive, and in writing. That covers design, engineering, permits, construction, finishes, appliances, and inspections. The only additional costs are city permit fees and utility connection fees, which typically total $8,000–$18,000 and are set by your city and local utilities.

Our Signature Homes range from roughly $380 to $550 per square foot depending on the model — and that includes everything, not just construction. Industry averages for Los Angeles ADUs run $350–$600+ per square foot for custom builds, but those numbers rarely include design, permits, or appliances. Our fixed price does.

In Los Angeles, ADU rental income ranges from approximately $1,800/month for a studio to $4,800/month for a three-bedroom two-story home. The exact amount depends on your neighborhood, bedroom count, and finishes. Use the calculator above to see estimated returns for each Signature Home model.

In most Los Angeles neighborhoods, yes. A Signature Home typically delivers a 5–10% cash-on-cash return with a payback period of 7–12 years — before factoring in property appreciation, tax benefits (depreciation), or annual rent increases. The combination of LA's housing shortage and fixed construction costs makes ADUs one of the strongest residential investments available.

No. The fixed price in our contract covers everything from design through certificate of occupancy. The only costs outside the contract are city permit fees (paid to your city) and utility connection fees (paid to your local water, power, and gas utilities) — both are set by the city/utility and quoted upfront during your consultation. We never add change orders for things we should have anticipated.
