Operating an Old Town / Mission Hills STR: what the rules actually say
Getting your permit is step one. Keeping it is the ongoing job. Old Town / Mission Hills follows the same citywide STRO rules as every other San Diego neighborhood — no special historic district restrictions that block eligibility. But there are practical realities unique to this area that you need to understand.
The rules below reflect the San Diego STRO ordinance as of March 2026. Old Town has standard enforcement near the State Historic Park and tourist corridor. Mission Hills is a quieter residential area with normal enforcement. HOAs in Mission Hills may add additional restrictions. The permit and any penalties remain tied to you as the owner, even if you hire a property manager.
Key rule summary
- Minimum 2-night stay — no exceptions, no platform workarounds
- No city-mandated minimum renter age — set your own house rules
- Post maximum allowable occupants per your Good Neighbor Policy
- Quiet hours: 10:00 PM – 7:00 AM daily (SDMC §59.5.04)
- 24/7 contact must respond to neighbor complaints within 60 minutes
- Permit number must appear on all listings and be posted inside the property
Occupancy limits
San Diego does not publish an official occupancy formula for STRs. Most hosts follow the common industry guideline of 2 guests per bedroom, plus 2. Your Good Neighbor Policy must state the maximum allowable occupants for your property. The same guideline applies in Old Town and Mission Hills.
| Bedrooms | Suggested Max Guests | Example Property |
|---|---|---|
| 1 bedroom | 4 guests | Studio / 1BR condo |
| 2 bedrooms | 6 guests | Old Town casita |
| 3 bedrooms | 8 guests | Mission Hills craftsman |
| 4 bedrooms | 10 guests | Old Town family home |
| 5 bedrooms | 12 guests | Bankers Hill estate |
Children count. A family of 4 with 2 kids counts as 4 guests, not 2. Day visitors who are not sleeping overnight are generally not counted in occupancy, but you are still responsible for any nuisance they create. There is no city-mandated minimum renter age — set your own house rules on your preferred booking age requirement.
Noise & quiet hours
San Diego enforces a citywide noise ordinance with quiet hours. Your designated 24/7 local contact must respond to any complaint within 1 hour. Old Town tourist foot traffic can mean more noise-adjacent situations than a typical residential street. Mission Hills is quieter but neighbors notice disruptions quickly in a residential setting.
Quiet Hours
10:00 PM – 7:00 AM daily (SDMC §59.5.04). Applies to all outdoor and indoor noise audible from the property line.
Music & Speakers
Outdoor speakers and amplified music are the #1 source of neighbor complaints. Consider prohibiting outdoor audio after 9:00 PM as a buffer.
Pool & Hot Tub
Pool equipment is generally exempt from noise rules, but guests using the pool after 10 PM create noise violations. Set clear check-out times for outdoor areas.
Response Time
When a neighbor calls about noise, your designated contact must respond within 60 minutes and resolve the situation. Document every response.
In practice, proactive house rules work better than reactive enforcement. Include quiet hour reminders in your check-in message, post them inside the property, and use noise-monitoring devices like Minut or NoiseAware to catch problems before they become citations.
Parking rules
Parking is one of the biggest sources of STR complaints in Old Town — tourist traffic makes street parking tight, especially during festivals and peak weekends. Mission Hills has easier residential street parking, but your listing must still accurately represent what is available. Never advertise more parking than you have.
Parking requirements by area
Old Town (near Historic Park)
Tourist traffic creates tight parking, especially on weekends and during festivals like Cinco de Mayo and Dia de los Muertos. Off-street parking is a major advantage. Read signs carefully.
Old Town (outer blocks)
Residential street parking is more available but still fills during major events. Confirm your on-site parking count before listing.
Mission Hills
Residential street parking is generally easy. No permit-restricted zones in most areas. HOA rules in condo complexes may restrict guest vehicles.
Bankers Hill
Walkable to Balboa Park. Street parking is competitive near the park entrances. Off-street parking adds real value to your listing.
Never advertise more parking than you have. If your listing says "2 parking spaces" and guests show up with 3 cars, you own the resulting complaint. Be conservative — it's better to under-promise parking than to over-promise and have a neighbor call the city.
Owner responsibilities
The permit is your responsibility — even if you hire a property manager. These are the obligations you accepted when you applied.
Nuisance Response Plan
Every STR permit holder must file a Nuisance Response Plan with the city. It must name a designated 24/7 contact — you or your manager — who can physically respond to the property within 30–60 minutes of a complaint. This contact must be reachable at all hours, including 2:00 AM on a Saturday.
Permit number on all listings
Your Short-Term Lodging Permit number must appear in every listing on every platform — Airbnb, VRBO, and any direct booking site. It must also be posted visibly inside the property. Listings without the permit number are non-compliant and can be flagged by the city or reported by neighbors.
Safety compliance
Your property must have functioning smoke detectors, carbon monoxide detectors, a fire extinguisher, and clearly posted emergency exit routes. These are inspected during the permit process, but you are responsible for maintaining them throughout the year. Guest injuries tied to non-compliant safety equipment create personal liability.
TOT remittance
You are responsible for collecting and remitting Transient Occupancy Tax even when platforms like Airbnb collect it on your behalf. If a platform fails to remit, the city looks to you. Keep records of every booking and every tax payment.
Accurate listing representation
Your listing must not misrepresent the property — including parking, bedroom count, occupancy, or amenities. Listings that attract more guests than permitted, or that imply amenities that don't exist, create liability and permit risk.
HOA & deed restrictions
A city STRO permit does not override your HOA's CC&Rs. If your HOA prohibits short-term rentals — or limits them to stays longer than 30 days — you are bound by those rules regardless of what the city allows. Mission Hills condos are the highest-risk area for HOA conflicts in this neighborhood. Old Town properties adjacent to the State Historic Park follow standard STRO rules with no additional historic district restrictions on private properties.
Before you apply for a city permit, verify:
- Your HOA's CC&Rs — specifically sections on rentals, leasing, and guest stays
- Any board resolutions passed since the original CC&Rs were written
- Whether deed restrictions on your specific parcel limit rental activity
- The Coastal Commission's special rules for properties in the coastal zone
Mission Hills condo complexes are the highest-risk area for HOA conflicts. The historic character of Old Town properties may also require extra care with exterior modifications — check with the city planning department before making visible changes. If you are unsure about your property, pull your CC&Rs and run them by a real estate attorney before investing in permit applications.
Violations & fines
San Diego's enforcement is complaint-driven but escalates quickly. The city actively investigates reports. Old Town's tourist foot traffic means neighbors and the city are paying attention. Do not assume a first-time violation will be overlooked.
| Offense Level | Typical Trigger | Consequence |
|---|---|---|
| First violation | Noise, parking, occupancy overages | Notice of violation, no fine — corrective action required |
| Second violation (within 12 mo.) | Repeat of any first-offense type | $500–$1,000 per day until corrected |
| Third violation | Any additional violation | $1,000–$2,500 per day + permit suspension hearing |
| Operating without permit | No valid STRO permit on active listing | Up to $2,500/day + mandatory permit revocation |
| Permit revocation | Pattern of violations or egregious single event | Permit voided — owner may not reapply for 12 months |
Fines accumulate daily until the violation is corrected and verified. A single party that triggers a weekend of noise complaints can result in 2–3 days of $2,500 fines before the city closes the case. The financial exposure from a single bad stay can erase months of rental income. Screening, clear house rules, and a responsive management presence are not optional.
