Rent & eviction protection

Is 4828 Mission St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1952
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The two-story, five-unit multi-family residential building at 4828 Mission Street in Mission Terrace, owned by 18239 Main Street LLC, has undergone numerous renovations and faced several challenges since its construction in 1952. Recent concerns include active complaints regarding building maintenance, with tenants reporting poor interior cleanliness and a tripping hazard due to a water hose at the entrance (September 2024). There are also significant ongoing investigations regarding an unauthorized structure built between the two buildings in the back parking lot (July 2023) and concerns about restricted access to tenant electrical meters (October 2022). The building has undergone substantial improvements over the years, including window replacements, kitchen and bathroom remodels in multiple units, roofing work, and electrical service upgrades to 200 amps. Several building violations were addressed between 2019-2020, primarily related to fire safety and smoke alarm requirements, and there have been multiple instances of garbage and debris removal requests in recent months.

The property has a documented history of maintenance and safety issues dating back to 2001, when several violations were recorded including damaged kitchen cabinets, broken tiles, and inoperative door bells. Most concerning are the periodic fire safety concerns, including blocked exits (2021) and a carbon monoxide incident (date unspecified), though no civilian injuries were reported in any fire-related incidents. The building has experienced various maintenance issues over the years, including plumbing and electrical work requiring multiple permits and inspections, some of which have only recently received final approval (most recently in 2023). Three recent calls regarding rodent/insect infestation (January 2025), and multiple reports of garbage and debris (December 2024), indicate ongoing maintenance challenges. While many improvements have been made to the property, including multiple unit renovations and safety upgrades, the building continues to face various maintenance and compliance challenges that impact resident comfort and safety.

Risk rating

How 4828 Mission St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
