Permits and roofing rules in Lynwood

What California requires everywhere

These are not specific to Lynwood, 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 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.

What a wildfire-zone roof actually has to include

Inside a mapped fire hazard zone the requirements go well beyond what the roof is covered with, and the extra details are exactly where a cheap job differs from a compliant one. It is embers rather than a flame front that destroy most houses in a wildfire, and every requirement below closes a gap an ember could use.

• 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

Tear-off waste and where it goes

CALGreen requires 65 per cent of nonhazardous construction and demolition waste to be diverted from landfill — but that chapter applies to additions and alterations that increase a building's conditioned area, volume or size, and a straight re-roof does not. So the state mandate generally does not reach a re-roof.

Local ordinances frequently do, and the state code expressly lets a city be stricter. Plenty of cities capture roofing through their own construction and demolition rules by permit valuation, which can mean a deposit and a diversion report on an ordinary house. Ask the city before the skip is ordered rather than after.

Licensing, deposits and what has to be on the paperwork

Roofing is the C-39 classification with the Contractors State License Board. The minor-work exemption that lets very small jobs be done unlicensed rose to $1,000 at the start of 2025, but it does not apply to work that requires a permit — and a re-roof requires a permit. The practical rule is therefore simpler than the statute: a re-roof needs a licensed contractor, whatever it costs.

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.

Fire classification: what is actually required, and where

Every ordinary re-roof has to meet at least a Class C fire-retardant covering. That floor applies to new roofs, to repairs and replacements, and to any existing building where over half the roof area is replaced inside a year.

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.

One citation to watch for: since 1 January 2026 the wildfire provisions are their own volume, the California Wildland-Urban Interface Code at Title 24 Part 7. It absorbed what used to be building code Chapter 7A and residential code section R337. Anyone still quoting Chapter 7A is quoting a superseded document.
