A buyer scrolling Del Mar listings this fall will find plenty of properties with a trailing twelve months of Airbnb or Vrbo income built right into the marketing copy. That income is real. The permit that produced it is not for sale, and under the city's own rules, it ends the day the property closes escrow.
California's Coastal Commission certified Del Mar's short-term rental ordinance on February 5, 2026, closing out a fight the city had been having with itself, and with the state, for roughly a decade. The commission's 7-2 vote in Half Moon Bay put the rules into effect immediately. What it didn't do was hand buyers a clean asset. It handed sellers a permit that's registered to them personally, capped citywide at a number the city had already exceeded before the ordinance took effect, and hard to replace once it's gone.
What actually happens at closing
The city's own short-term rental page spells out the mechanism plainly. Existing operators can keep running their rentals without complying with the new rules until their permit expires, isn't renewed, or the property is sold. Sale is listed right alongside expiration and non-renewal as one of the three ways a permit ends.
That means the trailing income on a listing sheet describes a business the seller built under registration rules that predate the current ordinance. It doesn't describe a right that rides along with the deed. When the sale closes, the registration doesn't transfer to the new name on title. The house transfers. A separate, harder path to short-term rental eligibility is what's left behind, and that path runs through a citywide cap that was full before most of today's buyers started looking.
The math behind the scarcity
Del Mar set its citywide cap at 129 short-term rental permits, calculated as roughly 5% of the city's total dwelling units under 2020 Census figures. That number was meant to leave room for both existing operators and future applicants. It didn't work out that way.
Back in September 2024, when the city council first adopted the ordinance, 120 properties had already registered as existing operators against that 129 cap. Del Mar's Principal Planner Amanda Lee told the council at the time that the math left almost nothing for new applicants, saying the city didn't "have much capacity for new" permits. Registration didn't stop there. By the time the window closed, 150 properties had registered as existing operators, all of them grandfathered in outside the 129 cap. The cap wasn't just tight. It was oversubscribed by grandfathering alone, before a single new applicant could apply.
| Cap category | Number | What it means for a new buyer |
|---|---|---|
| Citywide permit cap | 129 | The ceiling for permits available to anyone not already grandfathered in |
| North Beach sub-cap | 77 | A separate ceiling inside the 129 total |
| South Beach sub-cap | 32 | A separate ceiling inside the 129 total |
| Hills sub-cap | 19 | A separate ceiling inside the 129 total |
| Existing STRs registered | 150 | Grandfathered outside the cap, but tied to the current owner and lost at sale |
Why the waitlist might never open where you're looking
The 129 citywide cap isn't one shared pool. It's broken into three neighborhood-specific allocations: a maximum of 77 permits in North Beach, 32 in South Beach, and 19 in the Hills. A property can be sitting in a neighborhood with room under the citywide number and still have no path to a permit if that specific pocket has already reached its own ceiling.
The city hasn't published a current, address-level accounting of how each sub-cap is tracking as of this fall, and that's exactly the kind of thing that changes month to month as existing permits lapse or renew. A buyer weighing a specific Del Mar address should ask the city's planning division for the current count in that property's sub-area before assuming citywide headroom applies to them.
The residency requirement that wasn't there before
Here's the part that changes the economics for anyone buying with rental income in mind. Grandfathered operators were never required to live in the properties they rent out. A vacation rental property manager who spoke at the February 2026 Coastal Commission hearing, Kimberly Jackson, said most existing rental owners don't live in the homes they rent, and called the new rules a "de facto ban" for that reason.
New permits work differently. Anyone applying from the waitlist has to occupy the property as a primary residence for at least half the year. That single requirement rules out the pure investment model that built Del Mar's reputation as a strong short-term rental market in the first place. The income history on today's listings was generated by absentee owners operating under rules that no longer apply to new applicants. A buyer today, even one who eventually reaches the top of the waitlist in a neighborhood with room, has to actually live there.
The costs that apply either way
For anyone who does hold or eventually secures a permit, Del Mar set the initial permit fee at $815 and the renewal fee at $598, on a two-year cycle. Approved operators remit a 13% transient occupancy tax to the city through the Rentalscape platform, under Del Mar Municipal Code Chapter 3.12. The citywide minimum stay is three nights, a figure the city says it based on the average length of stay at short-term rentals in Del Mar and neighboring cities like Solana Beach.
None of those numbers are unusual on their own. What makes them relevant is that they apply to a much smaller pool of operators than the market's existing income data suggests, since more than half the current supply is running under a status that disappears at the next sale.
How Del Mar's rules compare along the coast
Encinitas got Coastal Commission certification the same day as Del Mar, but built its cap differently: a percentage-based system rather than a fixed citywide number, with a 2.5% cap on non-hosted rentals citywide and a separate 4% cap inside the coastal zone. That structure leaves more room to grow as the city's housing stock grows. Del Mar's council went the other direction, explicitly declining to let its 129-unit cap adjust automatically as new housing gets built, which means the number stays fixed unless a future council votes to change it.
A buyer cross-shopping Del Mar against Encinitas or Solana Beach for rental potential is comparing genuinely different regulatory systems, not variations on the same rule. Confirm the current framework in each city before building a pro forma that assumes one town's numbers apply to another.
What to verify before you write an offer
If a Del Mar listing's value case leans on short-term rental income, a few questions are worth answering before that number goes into your offer:
Ask whether the property's existing STR registration is currently active, and get it in writing rather than taking the listing sheet's word for it. Ask the seller's agent directly what happens to that registration at close, since the city's own language treats sale as an automatic end point. Contact Del Mar's planning division to check the current standing of that property's specific neighborhood sub-cap, North Beach, South Beach, or Hills, rather than relying on the citywide total. If you're planning to live in the home yourself and apply fresh, run your numbers against the three-night minimum and 13% transient occupancy tax rather than the seller's historical average, since your operating rules won't be identical to theirs even if you eventually get a permit.
A Del Mar address can still make sense as a short-term rental long after the sale closes. It just doesn't happen the way the listing sheet implies. The permit is the seller's, the cap is already spoken for, and the rules for anyone starting fresh are stricter than the rules that built the income you're looking at.
If you're evaluating a Del Mar property with rental income in the picture, it's worth having that conversation before you write the offer, not after. Ryan & Tracie can walk through what a specific address's permit status actually looks like and what it would take to requalify it under the current rules.
