What a adu / casita construction project looks like here

Apache Junction sits at the foot of Superstition Mountain — the city's eastern parcels face Pinal County hillside review in addition to AJ DS permitting.

Because a large share of Apache Junction housing stock consists of 1960s-1990s manufactured homes on owned land, replacement-with-site-built remodels require both demo permits AND new-construction permits as a sequenced workflow.

Many AJ parcels are >1 acre with septic systems rather than municipal sewer — kitchen and bathroom remodels frequently require ADEQ-permitted septic upgrades.

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 Apache Junction specifically, 1960s-1990s mobile + manufactured home base stock means adu / casita construction scope is shaped by the neighborhood's dominant construction typology.

Origin

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.
