Is a waiver the same as an exemption from Title 24?

No. It excuses the certificate only. The standard still applies to the work, and the department must still find in writing that the construction is designed to comply before it issues the permit.

Can I rely on what the counter told me for an earlier project?

Not safely. The edition follows the application date and departments set their own practice, so confirm what the new application needs.

Can a Building Department Waive the Title 24 Report? When "You Don't Need One" Is Allowed

Sometimes the paperwork, never the standard. For residential alterations that need no field verification, and for additions under 300 square feet that need none, the department may require no certificate or accept a simplified one. The work must still meet the Energy Code, and the allowance is the department's choice, not yours.

The clause behind "you don't need one"

Part 1, Section 10-103(a)1C names two cases: an alteration to an existing residential building where field verification is not required (water heater and window replacements are the examples), and an addition under 300 square feet where it is not required. In either, the enforcement agency may at its discretion require no certificate of compliance, or develop a simplified one. The word that matters is "may". It is a local choice, so a neighbouring city can answer differently.

What the waiver leaves in force

The clause says skipping paperwork is not authorization for work "in violation of this code". The new window or heater must still meet Part 6.
The department still cannot issue a permit without determining in writing that the construction is designed to comply, Section 10-103(d)1.
Replacing a regulated component is an alteration, not a repair, so a like-for-like swap is still in scope.
The matching clause for certificates of installation, Section 10-103(a)3D, is just as discretionary, so ask about both sets of forms.

What does not qualify

The discretion covers existing residential buildings only, not new buildings, additions of 300 square feet or more, or alterations that need field verification. For that last group, when the department does not ask for plans with the application, the certificate need not be approved before the permit but must be approved before final inspection, Section 10-103(a)2A.

How to ask, and what to keep

Ask the counter which form it accepts for your exact scope and have the answer noted on the permit record. Keep any simplified form and the product labels. A waiver does not travel: another department, or a later application, may ask for the full certificate. Scope examples are on window replacement permits and water heater permits. Settle the rest with 12 things to know before ordering, and if the department wants the full set, see residential Title 24 reports.
