ADU / casita construction in Siena
Siena is Summerlin (age-restricted 55+)'s single-story tuscan submarket. Siena is Del Webb's later Summerlin age-restricted community — built 1999-2010 with a tighter Tuscan palette than Sun City Summerlin and slightly larger homes, but the same single-story preservation rule.
What a adu / casita construction project looks like here
Siena is Del Webb's later Summerlin age-restricted community — built 1999-2010 with a tighter Tuscan palette than Sun City Summerlin and slightly larger homes, but the same single-story preservation rule.
Because Siena was developed across the IECC envelope-tightening transition (2000s), homes built 1999-2003 frequently fail current envelope standards on remodel — and homes built 2005-2010 typically pass without retrofit, splitting the cost-band by build-year.
The Siena CA ARC accepts modest contemporary updates within the Tuscan vocabulary — flat-top columns, smooth-coat stucco refresh, contemporary garage doors — but rejects modern-desert palettes outright.
Casitas, guest houses, and detached ADUs — Clark Co. + CLV by-right on most R-1 parcels with NSCB B-class license stack on the GC. In Siena specifically, single-story tuscan stock means adu / casita construction scope is shaped by the neighborhood's dominant construction typology. Baily's Las Vegas scoping flow factors siena community association arc and nscb b-class gc + aging-in-place specialty trades into the estimate before a contractor is involved.

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.
Questions LA homeowners actually ask
Siena adu / casita construction projects typically run $72K–$235K. Siena's single-story tuscan stock, combined with siena community association arc — age-restricted (55+) palette + single-story preservation, puts most mid-complexity projects in the $154K range. Baily scopes the exact band once you describe the work.
