This tells you what a rule says and where to read it. It never says a property is
compliant. Ordinances change, special-district boundaries do not follow city limits,
and published fees are often out of date — two escrow charts give Sausalito's report as $150
and $113 when the City charges $480. Open the source and confirm with the issuing agency
before you remove a contingency or set a closing date. Not legal advice.
The ones that bind before you list
These cannot be fixed during escrow. If the property is already on the market, they are late.
