Permits and roofing rules in Aliso Viejo

The statewide layer

These are not specific to Aliso Viejo, but they apply to it, and several of them are widely got wrong — including by contractors quoting from habit rather than from the current code.

The deductible, and the California version of the warning

California does not have a roofing-specific statute prohibiting a contractor from covering your deductible, in the way Texas and Florida do. That is not permission. The mechanism is what makes it illegal: a contractor who bills the insurer for the full amount while collecting less than the full amount from you has submitted a claim containing a false statement of material fact, and knowingly presenting a false or fraudulent insurance claim is a felony under Penal Code section 550, carrying prison terms and fines up to $50,000 or double the amount of the fraud.

The homeowner who agreed to the arrangement is a party to it. This is worth being blunt about because the offer is made constantly after storms and is almost always framed as a favour.

Licensing, deposits and what has to be on the paperwork

Roofing sits under the C-39 classification at the Contractors State License Board. The small-job exemption that permits unlicensed work rose to $1,000 in January 2025, but it does not extend to work needing a permit, and a re-roof needs one. So the rule that matters is the simple one: a re-roof requires a licensed contractor, at any price.

The deposit is capped by statute. A home improvement contractor may not take a down payment of more than $1,000 or ten per cent of the contract, whichever is less, unless they have a blanket performance and payment bond on file with the board. Exceeding it is a misdemeanour, and in a declared disaster area the court is required to impose the maximum fine — which tells you how commonly it is attempted after a storm.

Every licensed contractor is required to put the licence number in all advertising, and in contracts, subcontracts and bids. An advertisement without one is itself a signal. The board's own register will confirm a number in under a minute, and it is worth the minute.

What a wildfire-zone roof actually has to include

In a mapped fire hazard zone the requirements reach well past the covering, and they are the details that separate a compliant roof from a cheap one. Embers, not flame fronts, are what destroy most houses in a wildfire, and every one of these requirements is about closing a gap an ember could get through.

• A roof assembly meeting Class A when tested to ASTM E108 or UL 790
• On profiled tile, bird stops at the eaves and hip and ridge caps mudded in, so there is no open end for embers to enter
• Valley flashing of at least 0.019 inch (26 gauge) corrosion-resistant metal, over a mineral-surfaced cap sheet at least 36 inches wide
• Noncombustible gutters and downspouts, with an approved means of stopping leaves and debris collecting in them
• Vent screening of noncombustible corrosion-resistant mesh, no finer than 1/16 inch and no coarser than 1/8 inch

The right to cancel

The standard cancellation window on a home improvement contract is three business days, five for a senior citizen. Where the contract is to repair or restore damage from a disaster or a declared state of emergency, it is seven business days.

It exists precisely because of what happens in a neighbourhood after a storm. Nothing has to be signed on a doorstep, and if something was, the clock above is the reason to read it again tonight rather than tomorrow.

Tear-off waste and where it goes

CALGreen’s 65 per cent diversion requirement for construction and demolition waste attaches to additions and alterations that increase a building’s conditioned area, volume or size. A straight re-roof does none of those, so the state mandate generally does not reach it.

Local ordinances often do, and the state code explicitly allows a city to be stricter. Several cities capture roofing work through their own construction and demolition rules by permit valuation, which can mean a deposit and a diversion report on an ordinary house. It is a question for your city, and it is worth asking before the skip arrives rather than after.

Fire classification: what is actually required, and where

The statewide floor is a Class C fire-retardant roof covering. That applies to a new roof, to any repair or replacement, and to any existing building where more than half the roof area is replaced within a year — which is every ordinary re-roof.

Class A, the highest classification, is required where the property sits inside a fire hazard severity zone or a wildland-urban interface area, and many cities require it more widely by local ordinance. In practice, across most of south Orange County, Class A is the answer — but it comes from the fire zoning and the local ordinance rather than from a blanket statewide rule, so it is worth confirming for your address rather than assuming either way.

As of 1 January 2026 the wildfire rules live in their own book: the California Wildland-Urban Interface Code, Title 24 Part 7, which consolidated what used to be Chapter 7A of the building code and section R337 of the residential code. A contractor still citing Chapter 7A is citing something that has been superseded.
