What does adu construction actually cost in LA in 2026?

ADUs have become the single most popular home improvement in Los Angeles thanks to California's ministerial approval process - no public hearings, decisions inside statutory windows. A well-built 600-1,200 sqft ADU in West Hills or Woodland Hills can generate $2,000-$3,500/month in rental income, and studies show ADUs add 20-30% more value than their construction cost. Pricing runs $200-$400+/sqft in 2026, with detached standard at $200K-$300K and premium detached at $300K-$450K+. Total duration averages 6-12 months from design to move-in. Although LA's ADU process is streamlined, every parcel still requires zoning analysis, setback verification, utility capacity review, and overlay-zone checks before design investment.

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon's rim.

He wasn't the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily's contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily's beads.

That's what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner's real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That's our vibe too.
