ADU / casita construction in Tempe
Tempe is Tempe (separate jurisdiction)'s 1940s-1980s ranch submarket. Tempe is a separate municipal jurisdiction with its own building code and historic-district framework — Maple-Ash, University Park, and Mitchell Park East are locally-designated historic districts with their own design-review process.
What a adu / casita construction project looks like here
Tempe is a separate municipal jurisdiction with its own building code and historic-district framework — Maple-Ash, University Park, and Mitchell Park East are locally-designated historic districts with their own design-review process.
Because Tempe surrounds Arizona State University (the largest US university by enrollment), rental-occupancy regulations limit how many unrelated occupants can share a single-family home — design scope on student-rental conversions must respect occupancy caps.
Salt River and Tempe Town Lake floodplain on northern Tempe parcels requires base-flood-elevation review for any added ground-floor living space.
Phoenix legalized casitas/ADUs by-right in most R1 zones in 2024 (Z-TA-9-23) — Phoenix PDD residential permit, AZ ROC dual-license stack on the GC. In Tempe specifically, 1940s-1980s ranch stock means adu / casita construction scope is shaped by the neighborhood's dominant construction typology.

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
Tempe adu / casita construction projects typically run $75K–$245K. Tempe's 1940s-1980s ranch stock, combined with city of tempe (separate jurisdiction) — tempe cdd permits, puts most mid-complexity projects in the $160K range. Baily scopes the exact band once you describe the work.
