Why your current policy almost certainly doesn't cover your guests
Standard homeowners insurance is written for personal residential use. The moment you rent your property on Airbnb or VRBO — even once — you've converted it into a commercial activity. Most policies either contain exclusions that void claims arising during rental periods, or they contain language that allows the insurer to cancel your policy entirely if they discover you're operating a short-term rental.
Old Town and Mission Hills properties compound the risk. Older housing stock with potential structural issues, the Rose Canyon Fault seismic zone, heavy tourist foot traffic creating liability exposure, and the compliance stakes of an STRO permit that can be revoked — these aren't risks a residential homeowners policy was priced or structured to cover.
The gap nobody finds until it's too late
A guest trips on an uneven tile step in your Old Town courtyard at 11 PM and files a personal injury claim. Your homeowners insurer denies coverage because the property was occupied by a paying guest — a business activity excluded from your policy. Your property is exposed. This is not an edge case. It happens every year to owners who assumed their existing insurance "probably covered it." Older properties with original flooring and steps carry higher liability risk.

Top STR insurance providers for Old Town, San Diego
These three carriers are purpose-built for short-term rentals — not homeowners policies with an STR endorsement bolted on. All are A-rated and available in California. Which is right for you depends on how often you rent and how much coverage flexibility you need.
Proper Insurance
Best for full-time operatorsA-rated (A.M. Best)
$1,200–$2,500/yr for Old Town / Mission Hills 3-bed
Proper replaces your homeowners policy entirely with a commercial STR policy. It's the most comprehensive single-policy solution available and is officially endorsed by VRBO. If you're renting your Old Town or Mission Hills property year-round, Proper is the industry standard.
Pros
Replaces homeowners policy — no coverage gap
Wind/hail included as standard (not an add-on)
Unlimited loss of income — no coinsurance clause
Covers guest theft, bed bugs, squatters up to $10K
Liability covers on and off-premise incidents
Available in all CA zip codes including Old Town 92110
Cons
Premiums 20–30% higher than basic alternatives
No standalone endorsements — full replacement only
CBIZ Vacation Rental Insurance
Best for multiple propertiesA-rated (NYSE: CBZ)
$1,200–$3,000/yr for Old Town / Mission Hills 3-bed
CBIZ is the largest STR insurer in the U.S. by policy count. It's a strong choice for owners with multiple properties who want portfolio discounts, and it offers more flexibility on limits and deductibles than Proper. Available since 2002, it has deep experience with California markets including older housing stock.
Pros
Portfolio discounts for multiple Old Town / Mission Hills properties
Business income coverage up to 12 months with no time limits
Squatter legal fees covered up to $25K
Fine arts and antiques covered at market value
Flexible limits and deductible structures
Covers property arbitrage (renting a leased property)
Cons
Quotes require phone or form — no instant online pricing
Older properties may carry higher premiums due to replacement cost
Slice (via Safely or Allstate)
Best for part-time rentalsA-rated carriers
$800–$2,000/yr (Old Town / Mission Hills estimate)
Slice is built for occasional and part-time STR operators who want add-on coverage rather than a full commercial policy replacement. It integrates with platforms and can be activated per booking. Useful if you rent a few weeks per year, but insufficient as a primary policy for active Old Town or Mission Hills operators.
Pros
Flexible — coverage activates per booking
Lower cost for infrequent rental use
Simple tech integration with platforms
Cons
Not a full homeowners replacement
Standalone coverage in CA has limitations (confirm 2026 availability)
Not designed for full-time STR use in coastal markets
What your STR policy needs to cover
A complete STR policy for a Old Town, San Diego property isn't just liability coverage. Here's what the policy needs to address and why each matters in this specific market.
Property damage (replacement cost)
Pays to rebuild or replace damaged property at current costs — not depreciated value. Critical for Old Town and Mission Hills, where older Craftsman, Spanish Revival, and adobe-style homes cost significantly more to repair or rebuild with period-appropriate materials and techniques.
$1M+ liability coverage
Covers legal costs and damages if a guest is injured at your property. The $1M minimum is the industry standard. Given Old Town's heavy tourist foot traffic, older property conditions (uneven steps, original tile), and festival weekend crowds, $2M is worth pricing out.
Loss of rental income
Pays your rental revenue while the property is being repaired after a covered claim. During Old Town's peak festival season, a single month of lost income can be $5,000–$8,000. Make sure your policy has no coinsurance clause.
Guest-caused damage
Separate from property damage — this covers intentional or accidental damage caused by guests: broken furniture, stained linens, damaged appliances. Airbnb's AirCover covers this for Airbnb bookings, but you need coverage for direct bookings and VRBO.
Amenity liability
Pools, hot tubs, bicycles, kayaks, and paddleboards all create additional liability exposure. Make sure your policy either includes them or allows add-ons. Pool-related injuries are among the most common STR liability claims.
Bed bugs and squatters
Proper and CBIZ both cover these explicitly — up to $10K and $25K respectively. Bed bug infestations require professional extermination and result in multiple cancelled bookings. Squatter removal requires legal action and can take weeks.
Special endorsements Old Town / Mission Hills owners need
Even the best STR policy doesn't automatically cover every risk. These perils are excluded from standard policies and may require separate coverage — especially for older properties near the Rose Canyon Fault and in areas with any flood zone exposure.
Flood Insurance (NFIP)
Check Your ZoneMost Old Town and Mission Hills properties have low flood zone exposure — they're inland neighborhoods, not waterfront. However, properties near the San Diego River channel or in lower-lying areas may fall within FEMA-designated flood zones. If your property is in a designated zone and carries a federally backed mortgage, flood insurance is legally required. Your STR policy will not cover flood damage regardless of your zone classification.
Purchased through the National Flood Insurance Program (NFIP)
Cost: $500–$2,000+/year depending on zone and elevation
Most Old Town / Mission Hills properties are in minimal flood zones
Separate from your STR policy — maintained as a standalone policy
Check FEMA's Flood Map Service Center for your specific address
Earthquake Insurance (CEA)
Strongly Recommended in CAEarthquake damage is excluded from every standard homeowners and STR policy in California. Coverage is available through the California Earthquake Authority (CEA), a state-backed program, typically added as an endorsement through your primary insurer. Old Town sits near the Rose Canyon Fault, and many properties are older unreinforced structures that carry higher seismic risk. Ground movement is a when-not-if risk in Southern California.
Available through CEA via your primary insurer
Cost: $500–$1,500/year add-on for typical Old Town / Mission Hills home
Covers shaking, cracking, and ground movement
Seismic retrofitting can significantly reduce premiums on older homes
Maintained as a separate endorsement, not part of your STR policy
Wind & Hail Coverage
Included in Proper/CBIZ StandardWind and hail coverage is excluded from some base STR policies but included as standard with Proper and CBIZ. For Old Town and Mission Hills properties, southern California storms can cause real wind damage — particularly to older roofing, original windows, and mature trees on hillside properties. Verify your policy includes it — don't assume.
Included standard with Proper Insurance and CBIZ
May require an add-on with other carriers ($500–$1,500/year)
Covers roof damage, broken windows, and structural damage from storms
Important for properties with outdoor structures, pergolas, or deck furniture
What to budget for Old Town, San Diego STR insurance
Insurance costs for Old Town and Mission Hills STR properties are moderate compared to beachfront markets but still meaningful. Older housing stock, seismic zone proximity, high tourist foot traffic, and year-round rental activity all factor into premiums. Budget conservatively and treat insurance as a fixed operating cost, not a variable one.
| Coverage | Annual Cost (Old Town, San Diego) | Notes |
|---|---|---|
| STR policy (Proper or CBIZ) | $1,000–$2,500 | Base policy for active Old Town / Mission Hills STR |
| Flood insurance (NFIP) | $500–$2,000 | Only if in FEMA flood zone; most properties exempt |
| Earthquake (CEA) | $500–$1,500 | Add-on; depends on construction type |
| Wind/hail (if not included) | $500–$1,500 | Included in Proper/CBIZ; add-on elsewhere |
| Pool/hot tub liability rider | $100–$300 | If not included in base policy |
| Umbrella policy ($2M+) | $300–$700 | Extra layer above base liability |
| Fully covered (all perils) | $2,400–$8,000 | Older home, earthquake zone, full coverage |

Mistakes Old Town, San Diego STR owners make with insurance
Every one of these has cost an owner money. Most are discovered at the worst possible time — during a claim.
Relying on a standard homeowners policy
The most common and most costly error. Standard homeowners policies explicitly exclude commercial rental activity. A claim that arises while a paying guest is in the property will be denied. No exceptions.
Assuming Airbnb's AirCover is enough
AirCover has real gaps: it doesn't cover flood, earthquake, or wind; it's secondary to your own insurance; and it only applies to Airbnb bookings. If you take direct bookings or list on VRBO, you have zero platform coverage for those stays.
Underinsuring replacement costs on older homes
Old Town and Mission Hills properties — Craftsman homes, Spanish Revival, adobe-style buildings — cost significantly more to repair with period-appropriate materials and techniques. Insuring at assessed value instead of replacement cost means you'll come up short when a claim hits.
Skipping flood insurance because it's not required
NFIP requirements only apply to federally backed mortgages in mapped flood zones. But even outside required zones, properties near the San Diego River channel have flooded historically. Flood damage is excluded from every STR policy including Proper and CBIZ.
No coverage for amenities
Pools, hot tubs, kayaks, and outdoor furniture create liability exposure not covered by base STR policies. A guest injury in an uninsured pool can result in a lawsuit that your base liability policy denies because the amenity wasn't disclosed or covered.
Not telling your insurer you're running an STR
Some owners add an STR endorsement to their homeowners policy without disclosing the rental frequency or income. When a claim is filed, the insurer investigates, discovers the undisclosed rental activity, and denies the claim. Full disclosure is required.
Using a personal umbrella policy as a backstop
Personal umbrella policies follow your underlying homeowners policy. If the homeowners policy excludes STR activity, the umbrella excludes it too. You need a commercial umbrella that explicitly covers your STR operation to get extra liability protection.
