EVERY CLAIM LINKS TO ITS SOURCE.
When a page states a rule, it cites the ordinance section or statute and links to the original government text — not a summary of it.

ARIZONA RESIDENTIAL BUILDING RULES
A reference library on the rules that govern residential building in Greater Phoenix — the West Valley, Scottsdale, Phoenix, and the East Valley (Tempe, Mesa, Gilbert, Chandler), plus area guides for Ahwatukee Foothills and Laveen: state laws, county and city ordinances, and the questions homeowners actually ask.

/ HOW IT WORKS
ANSWERS YOU CAN CHECK
EVERY PAGE CARRIES A LAST-VERIFIED DATE.
Rules change. The date tells you when we last re-read the source. If a page is out of date, the date says so.
CORRECTIONS ARE ON THE RECORD.
When we get something wrong, the correction is published on the page, not quietly edited away.
ANSWERS COME BEFORE ANY SALES PITCH.
The answer on each page is complete on its own — including when the honest answer is that you don't need a contractor for the job.
/ WHAT'S IN THE LIBRARY
ONE SYSTEM, THREE PAGE TYPES
LAWS
One page per statute or ordinance: what the rule says, when it took effect, where it applies, what legal force it has, what's still unsettled, and a link to the original text.
CMS · STRUCTURED LEGAL RECORDSJURISDICTION GUIDES
One guide per permitting authority. Who issues your permit depends on where the parcel sits. Each guide identifies the authority, boundary caveats, and verified state-law thresholds; local rule detail appears only where it has been reviewed.
CMS · PERMITTING AUTHORITIES + AREA GUIDESANSWERS
Published as posts in the existing blog and tagged so this hub can index them. Direct answers to specific questions where the commonly repeated answer is wrong or incomplete, with the record laid out so you can check it.
