San Francisco Real Estate Regulations Buyers and Sellers Need to Know

Which agency answers each San Francisco real estate question?

What transfer taxes should San Francisco buyers and sellers understand?

San Francisco imposes a real property transfer tax when ownership is transferred or a deed is recorded. The rate is generally tied to the value or consideration involved, and the applicable schedule can change.

Do not assume that the buyer or seller automatically pays the entire amount. The contract, transaction structure, and local practice may affect how costs are allocated. Some transfers may qualify for different treatment or an exemption, but the details are fact-specific.

Before closing, ask the title or escrow company to confirm:

• The current San Francisco transfer tax rate
• Which party is responsible under the contract
• Whether the transfer qualifies for an exemption
• Whether the transfer is a conventional sale, entity transfer, gift, trust transfer, or other structure

The San Francisco Treasurer and Tax Collector’s transfer tax information should be checked for current rates and requirements.

How do property-tax reassessment and supplemental taxes work?

California law generally allows a property to be reassessed when there is a change in ownership or qualifying new construction. The reassessment may establish a new base-year value for property-tax purposes.

Afterward, California’s property-tax system generally limits annual increases to the applicable statutory amount, subject to exceptions. If the new assessed value differs from the prior assessment during the tax year, the buyer may receive a supplemental tax bill in addition to the regular property-tax bill.

A buyer should budget for:

• The regular secured property-tax bill
• A possible supplemental assessment
• Prorations handled through escrow
• Reassessment after a purchase or qualifying construction
• Potential differences between the seller’s current tax bill and the buyer’s future bill

The San Francisco Assessor-Recorder’s real-property assessment information is a useful starting point. A tax advisor should review the consequences of a particular purchase, ownership structure, reassessment, or exemption.

What is the difference between a tenancy-in-common and a condominium?

In day-to-day life, a buyer may not notice much practical difference between living in a condominium and living in a tenancy-in-common, often shortened to TIC. Both can provide an individual residence in a shared San Francisco building. The practical experience of living there may feel similar, but the legal ownership structure is not the same.

With a condominium, the buyer generally owns the individual unit and the defined interior space within its walls, along with an interest in the building’s common areas through the condominium association. The exact legal boundaries must be confirmed in the governing documents and title records.

With a tenancy-in-common, the buyer owns an undivided percentage interest in the entire building, rather than a separately deeded condominium unit. A TIC agreement typically gives the buyer the exclusive right to occupy a particular unit, but the ownership structure is different from condominium ownership.

Historically, many San Francisco TICs used a group jumbo loan, in which multiple TIC owners shared one loan. Today, many TIC buyers use fractional financing, meaning each buyer obtains their own loan for their fractional TIC interest. Financing availability, lender requirements, rates, and terms vary, so buyers should speak with multiple qualified lenders before making an offer.

The practical differences that can matter include:

• Financing: Loan options, underwriting standards, down-payment requirements, rates, and closing timelines can differ.
• Resale: The future buyer pool, marketability, and lender availability may not be the same for a TIC and a condominium.
• Separate title: A condominium unit is generally separately deeded, while a TIC interest reflects shared ownership of the larger property.
• Insurance: Coverage may be structured differently depending on the ownership form, master policies, and individual owner responsibilities.
• Maintenance: Responsibility for repairs, replacements, and shared expenses may depend on the condominium documents or the TIC agreement.
• Governing documents: A buyer should closely review the declaration, bylaws, house rules, budget, and association records for a condominium, or the TIC agreement and related shared-property documents for a tenancy-in-common.

San Francisco has a long history of tenancy-in-common ownership and condominium-conversion rules. Those rules can change, and a conversion may involve legal, financial, and timing considerations. Buyers should review the title, declaration, bylaws, TIC agreement, loan documents, insurance, and disclosures with a real-estate attorney, lender, insurance professional, and qualified real-estate agent.

Do San Francisco properties have soft-story retrofit requirements?

A soft-story building typically has a weaker or more open ground floor, often because of garages, parking areas, or large openings. During an earthquake, that configuration can create additional structural vulnerability.

San Francisco has operated seismic safety programs addressing certain wood-frame buildings, including soft-story properties. A building’s status may depend on its construction, number of units, configuration, prior permits, and applicable program requirements.

For a property under consideration, check:

1. Whether the building appears in a relevant city program or screening record
2. Whether retrofit plans were prepared
3. Whether permits were issued
4. Whether work was completed and finalized
5. Whether the homeowners association has discussed future structural work
6. Whether the building has open complaints or code issues

The San Francisco Earthquake Safety Implementation Program and Department of Building Inspection provide official starting points. A structural engineer: not a real-estate agent: should evaluate whether a building is safe or whether proposed work is adequate.

What are California exterior elevated element inspection requirements?

California law requires certain condominium associations to inspect qualifying exterior elevated elements, such as balconies, decks, walkways, stairs, and related waterproofing systems. These requirements are commonly associated with Senate Bill 326 and California Civil Code Section 5551.

The inspection report may address:

• The physical condition of the exterior elevated elements
• Waterproofing systems
• Remaining useful life
• Conditions requiring repair
• Recommendations for follow-up work

The requirements are part of California law, not a San Francisco-only regulation. If repairs are necessary, the repair work may require San Francisco building permits even though the inspection report itself is generally an association record.

For a condominium purchase, request the current homeowners association resale package and review the most recent applicable inspection report, board minutes, repair plans, and special-assessment notices. Requirements and disclosure rules can change, so the current California Civil Code should be consulted.

How should buyers research liquefaction, seismic risk, and earthquake insurance?

Liquefaction occurs when certain saturated soils lose strength during intense shaking. Some San Francisco areas, particularly parts of the filled waterfront and other low-lying areas, may appear on mapped hazard layers.

A map is a screening tool, not a property-specific engineering conclusion. Buyers should compare:

• The natural-hazard disclosure report
• The City’s San Francisco seismic hazard map
• Available California Geological Survey information
• Building permits and retrofit records
• Homeowners association engineering reports
• Insurance coverage and deductibles

Standard homeowners and condominium insurance policies commonly exclude earthquake damage. A homeowners association may carry a master policy, but that does not necessarily cover a unit owner’s personal property, interior improvements, temporary housing, or the full cost of a large assessment.

The California Department of Insurance earthquake guide explains coverage questions for homeowners, renters, and condominium owners. Ask an insurance professional to review the actual policy and deductible.

What rental restrictions and owner move-in rules may apply?

Rental restrictions may come from several sources:

• California law
• San Francisco’s Rent Ordinance
• The homeowners association’s governing documents
• Building-specific rental caps
• Short-term rental rules
• The lease and existing tenancy history

A condominium’s governing documents may limit leasing, require a minimum lease term, restrict short-term rentals, or maintain a rental cap. Investors should review these rules before assuming a property can be rented.

San Francisco owner move-in rules are separate from condominium rental restrictions. The San Francisco Rent Board’s owner or relative move-in information explains that notice, occupancy, filing, relocation, protected-tenant, and re-rental requirements may apply.

Owners and buyers should obtain legal advice before serving a notice, ending a tenancy, purchasing an occupied property, or relying on a future owner move-in plan.

What seller disclosures and condominium resale documents should include?

California seller disclosures and condominium disclosures serve different purposes.

A seller may need to disclose known facts about the property’s condition, including water intrusion, structural issues, alterations, defects, or other material conditions. Common transaction documents may include a Transfer Disclosure Statement and a seller questionnaire, although the exact requirements depend on the transaction.

A condominium resale package commonly includes:

• Declaration, covenants, conditions, and restrictions
• Bylaws and operating rules
• Current budget and financial information
• Reserve information
• Regular and special assessments
• Insurance summaries
• Litigation information
• Rental and occupancy restrictions
• Approved meeting minutes, when requested and available
• Applicable exterior elevated element inspection information

Fees, financial condition, repair plans, and building conditions are subject to change. Buyers and sellers should verify the information against the current resale package, budget, reserve study, meeting minutes, insurance documents, and disclosures.

For a deeper buying framework, review the San Francisco Buyer’s Guide. You can also explore current San Francisco condominium listings, including property-specific resources for 8 Octavia Street and 450 Hayes Street.

How can buyers check San Francisco building permits?

Use the Department of Building Inspection permit tracking system to search by address. Look for permits related to:

• Structural alterations
• Seismic retrofits
• Decks and balconies
• Plumbing and electrical work
• Unit reconfiguration
• Additions
• Open complaints or violations
• Final inspections and completion records

Permit records are useful, but they do not replace a professional inspection. Buyers should also confirm that the legal unit count, advertised square footage, finished areas, and material improvements match the official records and disclosure documents.

What should you do before buying or selling in San Francisco?

Start with the property address, not a generic checklist. Then:

1. Identify whether the property is a condominium, TIC, single-family home, or another ownership type.
2. Obtain current disclosures and homeowners association documents.
3. Check taxes, transfer-tax questions, permits, hazards, insurance, rental rules, and building records.
4. Ask qualified professionals to review issues outside an agent’s scope.
5. Compare the property with recent sales and competing inventory.
6. Build the findings into your offer, pricing, timing, and negotiation strategy.

Frequently asked questions about San Francisco real estate regulations

Does California law or San Francisco law control a real estate issue?

It depends on the issue. Property-tax reassessment, many disclosure requirements, TIC principles, and exterior elevated element inspections primarily involve California law. Transfer taxes, building permits, seismic programs, and rent rules may involve San Francisco requirements. Condominium documents can add another layer of property-specific rules.

Are San Francisco condominium fees and building conditions permanent?

No. Homeowners association fees, assessments, insurance costs, reserves, repair plans, and building conditions are subject to change. Verify them against current documents before relying on them.

Does a homeowners association’s earthquake policy cover my entire condominium?

Not necessarily. A master policy may cover defined common elements, while the unit owner may need separate coverage for personal property, interior improvements, temporary housing, and other risks. Ask an insurance professional to review the actual policies.

Can a buyer rely only on the City’s permit records?

No. Permit records are one part of due diligence. Buyers should also review disclosures, inspections, homeowners association documents, engineering reports, and title records.

Can an owner move into a San Francisco rental property whenever they choose?

No. Owner move-in rules can involve eligibility, notice, relocation payments, protected tenants, filing requirements, occupancy obligations, and re-rental restrictions. Obtain current Rent Board information and legal advice before taking action.

Who should review a complicated San Francisco condominium purchase?

A buyer may need several professionals: a real-estate agent, lender, title and escrow representatives, real-estate attorney, tax advisor, insurance professional, inspector, structural engineer, and homeowners association specialist.
