HOA Special Assessments in San Diego: How They Actually Work (2026)
Special assessment is the phrase that turns a good condo deal into an expensive mistake, and it's come up constantly in San Diego this year as SB 326 balcony inspections and rising insurance costs push HOA boards to bill owners for repairs the reserve fund can't cover. Most buyers know the term is bad news in a general sense without knowing the actual mechanics: what an HOA can legally charge without a vote, what triggers a full membership vote, how much notice you're entitled to, and who's actually on the hook for one if it hits right around a sale. Here's how special assessments actually work under California law, and what that means if you're buying or selling into a building carrying one.
What a special assessment actually is
Regular HOA dues cover the association's ordinary operating budget: landscaping, staffing, utilities on common areas, insurance premiums, and contributions to the reserve fund. A special assessment is a separate, one-time charge levied on top of those dues to cover something the regular budget and reserves weren't set up to handle, most often a capital repair or improvement: a roof replacement, a structural repair uncovered by an SB 326 balcony inspection, a plumbing repipe, or a large insurance deductible after a covered loss. Under California's Davis-Stirling Act, only capital improvements qualify, meaning the expense has to be mandatory for the community, substantially improve a common area, or significantly upgrade existing infrastructure. A board can't use a special assessment to plug an everyday operating shortfall the way it could with a dues increase.
The 5 percent rule: what a board can charge without asking owners
This is the number that matters most, and it's set by Civil Code Section 5605. A board can levy special assessments totaling up to 5 percent of the association's budgeted gross expenses for the fiscal year purely on its own authority, no membership vote required. That 5 percent figure is a cumulative annual cap, not a per-assessment limit, so an association with a $1 million annual budget can bill up to $50,000 in total special assessments across the year without putting it to a vote. Anything beyond that threshold requires approval from a majority of a quorum of the membership, decided by secret ballot under the same formal voting procedures the Davis-Stirling Act uses for other membership votes.
That 5 percent ceiling is exactly why a lot of the SB 326-driven repair bills showing up in San Diego right now end up going to a vote. Special assessments tied to balcony and structural repairs have run $40,000 to $175,000 per unit in some San Diego buildings once serious deferred maintenance was uncovered, numbers that blow well past 5 percent of a typical association's operating budget and force the board to put the expense in front of owners rather than simply billing it.
The emergency exception that skips the vote entirely
Civil Code Section 5610 carves out a real exception to both the 5 percent cap and the membership vote requirement. A board can levy a special assessment beyond the cap without a vote when the expense addresses an immediate threat to personal safety or significant property damage, when a court has ordered it, or when it covers a cost the board genuinely could not have reasonably foreseen at the time the annual budget was adopted. This is the provision that lets a board move fast after something like a failed elevator, a burst pipe that floods multiple units, or a balcony inspection that turns up an active safety hazard rather than routine wear. It's a meaningful power, and it's also the exception owners push back on most often, since "we couldn't have foreseen this" is a judgment call the board makes about its own planning.
Notice and payment rights owners actually have
Even when a board has the legal authority to levy an assessment, owners aren't left without protections on timing and payment. Civil Code Section 5615 requires the association to give individual written notice of a special assessment at least 30 days and no more than 60 days before it becomes due, and that notice has to spell out the amount, the reason for the assessment, the due date or dates, and any payment plan options. For larger bills, Civil Code Section 5650 gives real teeth to the payment plan piece: if a special assessment against a single owner exceeds $1,800, the association is required to let that owner pay it in installments over a period of at least 12 months. That threshold matters in San Diego specifically, since a lot of the SB 326-driven assessments land well above that $1,800 line, which means most owners facing one of these bills have a legal right to spread it out rather than paying a lump sum, even if the HOA's preferred structure is a single payment.
What's actually triggering these in San Diego right now
Three things are converging to push special assessments higher and more frequent across San Diego condo buildings this year. SB 326's mandatory exterior elevated element inspections, covering balconies, decks, walkways, and stairways six feet or more off the ground with wood-framed support, hit their first inspection deadline back on January 1, 2025, and associations now have to repeat the inspections every nine years. The inspection itself typically costs $5,000 to $20,000, but the real cost comes after, when the report finds problems: individual balcony repairs run $10,000 to $25,000, and buildings with broader structural issues have levied the $40,000 to $175,000 per-unit assessments mentioned above. Rising insurance premiums, climbing 15 to 30 percent annually for associations near canyons or coastal bluffs, are pushing some boards toward special assessments when a renewal comes in far above what the budget anticipated. And chronically underfunded reserves, a building sitting well under the 70 percent funded threshold that's generally considered healthy, leave a board with no cushion when a major repair does come up, since the money that should have been saved gradually simply isn't there.
What buyers are legally entitled to know before closing
California law puts real disclosure obligations on both the seller and the association here. The standard HOA resale disclosure package has to include any outstanding or anticipated special assessments, not just ones already billed, along with the reserve study, current financials, and insurance summary. As of January 1, 2026, SB 410 amended the Davis-Stirling Act to fold SB 326 inspection reports directly into that same disclosure package, so a buyer no longer has to chase that document down separately. If a board has discussed or approved an assessment that hasn't been formally billed yet, that's still something the association is expected to disclose, and it's worth asking about directly rather than assuming the paperwork will surface it on its own, since board discussions often run months ahead of a formal notice to owners.
Who actually pays a special assessment when a home sells
The default rule in most California purchase contracts is proration: the seller covers whatever portion of the assessment was due before closing, and the buyer picks up what's due afterward, the same logic used for property taxes and regular dues. But that default can get overridden in two ways worth knowing about. Some HOA governing documents include a due-on-sale or acceleration clause, which makes the entire remaining balance of an installment assessment come due the moment title transfers, meaning a seller can't simply hand off future installments to the buyer the way the default proration would suggest. And regardless of what the governing documents say, buyers and sellers can negotiate their own arrangement directly in the purchase contract, whether that's the seller paying the assessment off in full before closing, a credit at closing in lieu of payoff, or the buyer agreeing to assume the remaining balance in exchange for a lower purchase price. None of this happens automatically. It has to be addressed explicitly in the contract, and it's a common point of last-minute renegotiation once a buyer discovers a pending assessment during their disclosure review.
What this means if you're selling
Get ahead of any pending or anticipated assessment before you list, since it's going to surface in disclosures regardless and buyers respond far better to a seller who raises it upfront than one who lets it come out during their own due diligence. If the assessment is already billed, decide whether you're going to pay it off before closing, offer a credit, or ask the buyer to assume it, and be ready to negotiate on price if you're asking a buyer to take on a real dollar amount. And check your association's governing documents for a due-on-sale clause before you assume any installment plan can simply transfer to the new owner.
What this means if you're buying
Ask specifically whether any special assessment has been billed, approved, or even discussed by the board in the past year, not just whether one currently exists, since board discussion often runs well ahead of a formal notice. Review the reserve study's percent funded figure alongside the SB 326 inspection status, since a building that's both underfunded and overdue on inspection is the profile most likely to produce a large assessment shortly after you close. And if you do end up assuming a pending assessment as part of the deal, confirm in writing whether it exceeds the $1,800 installment threshold, since that determines whether you have a legal right to spread the payment out rather than paying it in a lump sum.
The bottom line
A special assessment isn't automatically a red flag, buildings that keep up with maintenance sometimes still need one, but the legal mechanics around it, the 5 percent cap, the emergency exception, the notice and installment rights, and the disclosure requirements, determine how much warning you actually get and how much leverage you have once one shows up. Whether you're pricing a listing that's carrying one or evaluating an offer on a building that might be headed toward one, the paperwork tells you more than the HOA dues line on a listing sheet ever will.
