HOA Solar Access Rights and Tree Shading Disputes: California Civil Code §714 and Solar Easements

Civil Code §714: What HOAs Cannot Do

California Civil Code §714 provides that any CC&R, covenant, or restriction in a governing document that effectively prohibits or unreasonably restricts the installation or use of a solar energy system is void and unenforceable. This is a strong statutory override: an HOA cannot refuse to approve a solar installation on the grounds that the board simply doesn't want solar panels visible on rooftops.

However, §714 allows HOAs to impose reasonable restrictions on solar installations — restrictions that do not significantly increase the cost of the system (defined as an increase of more than $1,000 or a reduction in efficiency of more than 10%) or significantly decrease its efficiency. Common reasonable restrictions that courts and the California Solar Rights Act contemplate include: requiring that panels be installed flush with the roofline rather than tilted on a flat roof (if technically feasible), requiring approval of panel brand or color where reasonable alternatives are available at similar cost, and requiring panels to be installed on the rear slope of the roof rather than the front (if that placement does not violate the 10%/1,000 cost thresholds).

The key test is whether the restriction “significantly” increases cost or decreases performance. A restriction that saves the HOA's visual aesthetics at the cost of making the solar installation economically infeasible fails the test. A restriction that results in a modest placement change with minimal cost impact is likely enforceable.

Solar Easements: Creating an Enforceable Sunlight Right

California Civil Code §801.5 allows property owners to create a solar easement — a recorded property right that entitles the solar installation owner to receive sunlight across the land of another at specified angles and times. A solar easement, once properly recorded, runs with the land and binds subsequent owners of the burdened parcel.

A solar easement must be in writing, must describe the dominant and servient parcels with specificity, must describe the space across which the easement runs (the solar sky space — the area above the burdened property through which sunlight must pass to reach the panels), must state the dates and times of day when the easement applies, and must be recorded with the county recorder. Oral agreements to not plant shade-producing trees are not enforceable as solar easements.

In an HOA context, a solar easement on common area is more complex — it would require association approval to burden the common area with an easement benefiting a single owner's unit. This typically requires board approval or, depending on the nature of the encumbrance, membership vote. Most HOA solar installations proceed without formal solar easements, relying instead on the Solar Shade Control Act (for neighboring trees) and general goodwill for placement planning.

The Solar Shade Control Act

California's Solar Shade Control Act (Public Resources Code §25980–§25986) provides some protection against shading by vegetation — but its protections are narrower than many solar owners assume. The Act prohibits a person from allowing a tree or shrub that was planted after January 1, 1979, to shade more than 10% of the solar collector's absorption area between 10 a.m. and 2 p.m. — but only if the solar installation was in place before the vegetation was planted.

The Act has significant limitations. It does not apply to trees that were planted before the solar system was installed. It does not apply if the cost of trimming or removing the shading vegetation would be unreasonable compared to the value of the solar installation. And it does not apply to trees on common area in an HOA if the association planted the tree before the member installed their panels.

An owner who installs solar panels on a roof and then discovers that a neighbor subsequently plants fast-growing trees that shade the array may have a Solar Shade Control Act claim — but should document the planting date carefully and be prepared for the neighbor to argue that trimming costs are unreasonable. An owner who installs panels knowing that mature trees already partially shade the proposed installation has no Solar Shade Control Act claim against those existing trees.

HOA Common Area Trees and Solar Shading

In planned unit developments and condominium communities, many of the trees near solar installations are in common areas maintained by the association. When association-maintained trees grow to shade a member's solar panels, the member may request that the association trim the trees to restore solar access.

The board's obligation to accommodate this request depends on the governing documents, when the trees were planted relative to the solar installation, and whether the association's landscaping decisions are subject to business judgment review. An association that planted trees before the solar installation was installed generally has no legal obligation to trim them to accommodate the later installation — the member assumed that risk by installing panels in a location that could be shaded by existing landscaping.

Conversely, an association that plants new trees after a member installs solar panels, and those trees shade the installation, may be subject to the Solar Shade Control Act and potentially to a claim that the association has unreasonably interfered with the member's solar energy system in violation of Civil Code §714. Before approving new planting near solar installations, the board should consider the potential shading impact and whether the planting could expose the association to a solar shading claim.

Practical Steps for HOAs and Solar Owners

For HOA boards: establish a clear solar installation approval process that specifies placement and aesthetics criteria consistent with §714's limits (no restrictions that add more than $1,000 in cost or reduce efficiency by more than 10%). When approving a solar installation, note in the ARC approval that the association makes no representation about shading from existing landscaping. Before approving new landscaping near existing solar installations, assess the potential shading impact.

For members installing solar: before choosing a panel location, document the current shading conditions from all surrounding trees and structures. If a solar easement is needed to protect the installation from future growth by a neighboring owner's plantings, negotiate and record the easement before installing — it is much harder to obtain after the panels are in and a dispute has arisen. Consider having the solar installer provide a shading analysis that is retained with the ARC approval file, documenting that the system was installed with known shading taken into account.
