AB 2099 adds Section 5208.3 to the Business and Professions Code to define “customary maintenance” for outdoor advertising displays. The text explicitly covers activities performed to keep a display in its existing physical configuration, including replacing structural members (for example, posts and internal bracing) and using stronger materials, provided the number of posts does not increase.
The change matters because California’s Outdoor Advertising Act already prevents governmental entities from restricting customary maintenance of lawfully erected displays without payment of compensation. By clarifying that certain structural replacements and material upgrades are “customary maintenance,” the bill narrows the circumstances in which local governments can treat upgrades as new construction subject to permit conditions, design limits, or compensation requirements.
At a Glance
What It Does
The bill creates a statutory definition of “customary maintenance” in Business and Professions Code §5208.3 that expressly includes replacing structural members and adopting stronger materials, so long as those activities do not increase the number of posts used by the display.
Who It Affects
Outdoor advertising owners and operators, sign manufacturers and maintenance contractors, and local and state agencies that regulate roadside signage (including permitting and building-code enforcement) are directly affected. Advertisers and property owners hosting displays will also see reduced permitting friction for certain upgrades.
Why It Matters
The definition limits when governmental entities can treat work on an existing display as a prohibited alteration, tightening a protection that may already shield sign owners from some local restrictions and lowering barriers for structural upgrades without triggering compensation obligations.

What This Bill Actually Does
AB 2099 is short and focused: it inserts a definition into California’s Business and Professions Code that clarifies what counts as “customary maintenance” for outdoor advertising displays. The definition centers on keeping a lawfully erected display in its existing physical configuration.
It lists replacing structural members—posts and internal bracing—as examples of allowable maintenance and also permits the use of stronger materials during those repairs or replacements.
A key textual limit is that customary maintenance cannot increase the number of posts supporting the display. That condition serves as the bill’s primary boundary between maintenance and what would more likely be treated as a new or materially altered structure.
The statute does not define other terms the phrase invokes—most notably “existing physical configuration” and “stronger materials”—so practical application will depend on how regulators and courts interpret those phrases.Because the legislative digest notes that the Outdoor Advertising Act bars governmental entities from limiting customary maintenance of a lawfully erected display without compensation, this statutory definition has immediate regulatory consequences. Sign owners will point to §5208.3 to argue that structural repairs and material upgrades are protected maintenance activities, while local agencies will need to recalibrate permitting, inspection, and code-enforcement practices to account for the narrower set of permissible regulatory actions.
That shift creates both compliance simplicity for sign operators and potential disputes over where maintenance ends and alteration begins.
The Five Things You Need to Know
The bill adds a new statutory definition—Section 5208.3—to the Business and Professions Code that defines “customary maintenance” for advertising displays.
Customary maintenance expressly includes replacing structural members, such as posts and internal bracing, performed to preserve the display’s existing physical configuration.
The definition permits the use of stronger materials when performing maintenance, without describing material types or performance thresholds.
A categorical limitation in the text: maintenance activity must not increase the number of posts supporting the display.
Because the Outdoor Advertising Act prevents governments from restricting customary maintenance of lawfully erected displays without compensation, this definition narrows the situations where local agencies can treat structural work as a compensable interference or a new installation.

Statutory definition of ‘customary maintenance’
This single statutory provision defines “customary maintenance” as activity performed to maintain a display in its existing physical configuration. It provides two concrete examples—replacing structural members (posts and internal bracing) and using stronger materials—while imposing the explicit constraint that the number of posts may not increase. Practically, that means the Legislature intends some structural repairs and material upgrades to be treated as routine maintenance rather than as new construction or a modification that would permit local regulation or require compensation.
What the text allows and what it leaves unsettled
By naming posts and internal bracing, the bill clears the way for routine load-bearing repairs and retrofits (for example, swapping rotted posts for treated timber or steel or replacing corroded bracing). However, the statute does not quantify ‘‘stronger’’ or define ‘‘existing physical configuration,’’ so work that changes dimensions, sightlines, or sign surface area could still be contested. The prohibition on adding posts is a bright-line limit but does not address changes to post placement, attachment points, or the display face.
How this definition interfaces with permits, building codes, and compensation law
Although the bill speaks only to a statutory definition, it operates inside an existing legal framework that restricts government limits on customary maintenance without compensation. That interaction suggests sign owners will invoke §5208.3 in administrative and judicial proceedings to oppose local permit requirements or design restrictions for qualifying repairs. Building officials retain authority over public-safety code compliance, but they will need to distinguish between maintenance covered by §5208.3 and work that triggers standard permitting because it alters the structure beyond the definition's limits.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Outdoor-advertising companies and sign owners — The definition reduces regulatory risk when they replace structural members or upgrade materials without increasing post count, lowering the chance that routine repairs will be treated as new construction requiring permits or compensation.
- Maintenance and fabrication contractors — Firms that perform structural repairs or material upgrades gain clearer grounds to perform work without the added cost and delay of local review, expanding billable maintenance work.
- Advertisers and property owners hosting displays — They face fewer interruptions when owners conduct permitted maintenance and may see lower downtime and transaction costs for keeping displays operational.
Who Bears the Cost
- City and county planning and building departments — Local regulators lose a regulatory lever and may face more administrative disputes or litigation as they reconcile safety inspections and aesthetic controls with the new statutory protection for maintenance.
- Community groups and local residents concerned about visual blight — A broader maintenance definition can make it harder to limit incremental visual changes that cumulatively affect scenic character or neighborhood aesthetics.
- State and local safety regulators — Although the bill does not remove code authority, it can complicate enforcement by narrowing when work is presumptively subject to local review, potentially shifting the burden to officials to prove alterations exceed maintenance.
Key Issues
The Core Tension
The bill forces a tough choice between protecting property owners’ ability to keep lawfully erected displays safe and functional and preserving local governments’ ability to control changes that affect safety, aesthetics, and traffic distraction: it narrows grounds for local regulation to favor maintenance, but does so with language broad enough to invite dispute about where maintenance stops and impermissible alteration begins.
The bill’s practical effect depends on how undefined terms get interpreted. Phrases like “existing physical configuration” and “stronger materials” create real litigation risk because they leave room for competing factual claims: a sign owner can argue that replacing timber posts with steel maintains configuration while a municipality can argue the substitution materially alters structural capacity or appearance.
Courts or agencies will need to develop tests—e.g., whether dimensions, footprint, or display face change—to distinguish maintenance from alteration.
There is also a safety-versus-preemption problem. The Legislature protects certain maintenance activities from regulatory restriction without compensation, but building codes and safety inspections remain essential.
The bill does not say that local building-code obligations are overridden; however, local authorities may have to justify inspections or permit denials on safety grounds rather than as land-use or aesthetic regulation. That raises administrative and fiscal issues for jurisdictions asked to provide more specific, evidence-based findings when they act.
Finally, the provision’s emphasis on not increasing post count is a narrow boundary that may encourage sign owners to pursue other modifications (stronger materials, repositioned attachments) to accomplish functional upgrades while keeping post count stable. That dynamic could produce incremental changes with significant aggregate effects on size, visibility, or structural performance, complicating both enforcement and community expectations.
