Balcony Inspections in San Francisco and Marin: SB 721, SB 326 & Section 604
A working guide to California's exterior elevated element inspection laws, San Francisco's local Section 604 ordinance, and the seller's playbook for any multi-unit owner or HOA board navigating compliance and a future sale.
California's SB 721 and SB 326 require periodic inspections of exterior elevated elements (balconies, decks, stairways, landings, and walkways) more than six feet above the ground on multi-unit residential properties. SB 721 applies to rental buildings of three or more units. SB 326 applies to condominium and cooperative HOAs of three or more units. San Francisco buildings may also fall under Section 604 of the San Francisco Housing Code, a separate local ordinance that has been in effect since 2002 and can apply independently of state law. SB 326's first inspection deadline was January 1, 2025. SB 721's first inspection deadline was January 1, 2026 (extended from January 1, 2025 by AB 2579). Both first-cycle deadlines have passed, which means owners and HOA boards that have not completed an inspection are out of compliance, with practical consequences at sale, refinance, and disclosure. This guide covers what each law requires, the differences between them, how Section 604 layers on, what happens at a sale when the inspection has not been done, and the playbook for a building owner getting compliant ahead of a listing.

Why post-deadline compliance matters now
The first inspection deadlines for both SB 326 (HOA-governed buildings) and SB 721 (rental multi-unit buildings) have come and gone. SB 326's deadline was January 1, 2025. SB 721's deadline was January 1, 2026 (extended from January 1, 2025 by AB 2579). For owners and HOA boards that completed inspections on time, the requirements are part of the long-tail compliance calendar, a recurring item that comes back every six or nine years depending on which law applies. For owners that did not, the building sits in a more uncomfortable category: technically non-compliant, with the consequences most often surfacing at a real estate transaction.
In a sale, the buyer's agent and the lender will ask. In a refinance, the lender will ask. In a disclosure package, the question of whether an SB 721 or SB 326 inspection has been performed is now a standard line item, and the answer of "not yet" opens a conversation that can pressure timing and price. None of this is fatal. Inspections can be scheduled, repairs can be scoped, and a building can be brought into compliance ahead of any transaction with enough lead time. What rarely works well is leaving the question open until the property is already on the market. The right move for any owner who has not completed the inspection is to start the process before anyone else is asking.
SB 721: the rental-building inspection law
Passed in 2018 and driven in significant part by the 2015 Berkeley balcony collapse, SB 721 applies to multifamily residential rental buildings of three or more units. It requires periodic inspection of exterior elevated elements, including balconies, decks, stairways, landings, and walkways, that are six feet or more above the ground and that depend in whole or in part on wood or wood-based products for structural support.
What SB 721 requires
- An initial inspection by January 1, 2026 — extended from January 1, 2025 by AB 2579 — which has now passed
- Subsequent inspections every six years
- Inspection by a California-licensed architect, civil or structural engineer, or qualified building contractor with the appropriate license
- A written report identifying any unsafe conditions, with repairs generally required within 120 days of the report (emergency hazards must be addressed immediately)
- Penalties for non-compliance can include civil fines (up to $500 per day) and recorded liens on the property
In practice, the law applies most directly to traditional small and mid-sized multi-unit rental buildings: 3-unit Edwardians, 4-unit walk-ups, and larger apartment buildings. If you own a 3-unit or 4-unit rental property in San Francisco or Marin with any wood-framed balcony, walkway, fire escape, or elevated stair, SB 721 almost certainly applies to your building.
SB 326: the HOA inspection law
Signed in 2019, SB 326 addresses the same general structural concern as SB 721 but is written for condominium associations and cooperative housing managed by HOAs of three or more units. The substance is similar (inspect the wood-framed exterior elevated elements, document the findings, plan for repairs) but the procedural framework runs through the association rather than the individual owner.
What SB 326 requires
- Initial inspection by the HOA by January 1, 2025 (this deadline has passed)
- Subsequent inspections every nine years
- Inspection by a California-licensed structural engineer or architect only (no contractor option, stricter than SB 721)
- Findings must be incorporated into the HOA's reserve study, which makes the inspection result a long-term capital planning document rather than a one-time report
- HOA boards that fall behind face legal and financial exposure on behalf of the association and its members
For a small condominium HOA, this is the law that quietly carries the most operational weight. The inspection requirement layers onto the reserve study requirement, which means the result drives both the dues structure and the long-term repair planning. For a condo seller, the question of whether the HOA has completed its SB 326 inspection is one that the buyer's agent will surface in the disclosure review, and the answer matters.
San Francisco Section 604: the local ordinance
Layered on top of state law, Section 604 of the San Francisco Housing Code creates a separate local inspection requirement for the city's multi-unit buildings. It is the oldest of the three frameworks — in effect since 2002 — and covers many of the same exterior elevated elements (balconies, decks, stairs, fire escapes, and projections), but is enforced locally through the San Francisco Department of Building Inspection rather than through state law. Compliance with Section 604 is required independently of SB 721 or SB 326. A San Francisco building can owe compliance under both the state and local frameworks.
Key points on Section 604
- Applies to San Francisco apartment buildings, residential condos of 3+ units, and hotels with six or more guest rooms
- Recurs every five years (more frequent than either state law)
- Requires inspection of 100% of exterior elevated elements — stricter than SB 721's 15% sampling
- Enforced locally through the San Francisco Department of Building Inspection (DBI), Housing Inspection Services Division
- Requires a signed compliance affidavit filed with the City; buyers, lenders, and title companies increasingly look for it alongside the state documentation
For sellers, the practical implication is that "I'm SB 721 compliant" and "I'm Section 604 compliant" are not the same statement, even though the inspections often examine the same physical elements. A complete pre-sale readiness package documents both. The City publishes the Section 604 compliance affidavit on sf.gov.
SB 721 vs SB 326 vs Section 604: side-by-side
Three frameworks, three different applicability standards. The honest read for any owner is to identify which one (or which combination) governs the specific property, then plan compliance accordingly.

Selling a 3+ unit building or HOA-governed condo?
If you own a multi-unit property or sit on an HOA board and a sale is on the radar in the next year or two, the EEE inspection is one of the cleanest pieces of pre-sale prep you can knock out. Start with a real read on what the property is worth in today's market, then we'll map the compliance and prep timeline backwards from your target list date.
The seller's playbook for a multi-unit building or HOA-governed condo
For any owner planning to list a 3+ unit building, a small HOA-governed condominium, or a multi-unit San Francisco property with wood-framed exterior elevated elements, the EEE inspection is part of the pre-sale checklist alongside the typical disclosure package, the natural hazard report, the 3R report, and the pre-sale inspector's walk. Four parts of the playbook tend to matter most.
1. Get the inspection done before you list, not after the offer
The cleanest path is to complete the EEE inspection (and any required repairs) before the property hits the market. The report becomes part of the disclosure package the buyer sees on day one, repairs are scoped on the seller's timeline, and the buyer never gets the leverage that comes from discovering an open compliance question mid-contract. The pattern that converts is a complete, organized, frontloaded package. The pattern that creates problems is a "we'll address it during escrow" posture.
2. Choose an inspector who knows the SF and Marin housing stock
The right inspector for a San Francisco Victorian rental, a Marin condo HOA podium, or a Sunset-era stucco building is not the same person. The wood-framed details, the typical failure modes, the architectural quirks, and the access constraints all differ by neighborhood and era. On a Hayes Valley listing I represented, the inspection was performed by Great Escapes, a San Francisco firm that handles a high volume of EEE work in older multi-unit buildings. The report came back clean, the documentation was tidy, and the property closed at $3,363,000 (35% over the $2,495,000 list price, seven days on market, eleven offers). The inspector you hire is part of the marketing of the property, not a line item buried in the file.
3. Disclose proactively, do not react
Once the inspection is complete, the report belongs in the disclosure package on the first day of marketing. Buyers and their agents value the proactive posture, and pre-emptive disclosure removes one of the most common late-stage negotiation levers a buyer can use. If the inspection identifies items requiring repair, the disclosure should also document what was scoped, what was completed, by whom, and the final clearance. Treat the package as the marketing asset it is.
4. Plan for repairs, not just inspection
For older multi-unit buildings in San Francisco and Marin, an EEE inspection of wood-framed exterior elements rarely comes back with zero findings. Dry rot, deferred painting, compromised waterproofing under a wooden deck, all surface from time to time. The right read is that the inspection is the start of the work, not the end of it. Budget for likely findings, build a small contingency into the pre-sale prep, and treat the repair scope as part of the listing strategy. For HOAs, the SB 326 process layers this work onto the reserve study, which means the long-term capital planning becomes more rigorous, not less. Treat that as an asset in the disclosure conversation.
A working example: 436 Oak Street, Hayes Valley
436 Oak Street is a street-to-street Hayes Valley Victorian I represented as the listing agent: a 3-unit property with a 4-bedroom owner's residence over two one-bedroom units, three parking spaces, and frontage on both Oak and Hickory. As a 3+ unit rental-configured building, the property fell squarely inside the SB 721 framework, and the EEE inspection was part of the pre-sale checklist alongside staging, photography, and the rest of the disclosure prep. Great Escapes handled the inspection. The report came back clean, the documentation went straight into the disclosure package, and the property went on the market with the compliance question already resolved.
The takeaway for any owner of a 3-unit or 4-unit building thinking about a sale: handle the EEE inspection up front. Buyers respond to a complete package, and the inspection is one of the cleanest pieces of homework you can finish before the first showing. The full sale write-up is documented in 436 Oak Street, Hayes Valley.

Frequently asked questions
What is the difference between SB 721 and SB 326?
SB 721 applies to multifamily rental buildings of three or more units. SB 326 applies to condominium and cooperative HOAs of three or more units. Both require periodic inspection of exterior elevated elements that are six feet or more above the ground and depend on wood for structural support. The inspector qualifications and inspection cycles differ: SB 721 allows architects, engineers, or qualified contractors and requires inspection every six years. SB 326 allows only structural engineers or architects, requires inspection every nine years, and folds the result into the HOA reserve study.
Both first-cycle deadlines have passed. What happens now if my building is not compliant?
For SB 326, the first inspection deadline was January 1, 2025. For SB 721, the first deadline was January 1, 2026. A building that has not completed the inspection is technically non-compliant. The most common consequences arise at sale, refinance, or disclosure review, where buyers, agents, lenders, and title companies will ask whether the inspection has been performed. Civil penalties and liens are available under SB 721. HOA-level legal exposure is available under SB 326. The right path is to schedule the inspection and move toward compliance rather than wait for an enforcement event or a transaction to surface the question.
Does this apply to single-family homes?
No. Neither SB 721 nor SB 326 applies to standalone single-family residences. The laws are written for multi-unit buildings of three or more units. If a single-family home is part of a duplex or part of a condominium association, the analysis shifts: a duplex falls outside both state inspection laws, while a condo unit inside a 3+ unit HOA falls under SB 326 via the association.
How does SF Section 604 fit in?
Section 604 of the San Francisco Housing Code is a separate local ordinance, in effect since 2002 and enforced through the San Francisco Department of Building Inspection. It runs on a five-year cycle, requires inspection of 100% of exterior elevated elements (stricter than SB 721's 15% sample), and can apply alongside SB 721 or SB 326. A San Francisco multi-unit building may owe compliance under both the state law and the local Section 604 framework, and each has its own documentation. For sellers, a complete pre-sale package documents both. The City publishes the Section 604 compliance affidavit on sf.gov.
What if my building was recently remodeled?
If the exterior elevated elements were constructed or substantially reconstructed within the last fifteen years and you have permit documentation showing the work was signed off, the building may be exempt from an immediate first inspection cycle under SB 721. Documentation is the key. Without permitted closure paperwork, the exemption argument is hard to make and a fresh inspection is the cleaner path. SB 326 does not have a parallel new-construction exemption, so the HOA still owes the inspection cycle.
Who can perform the inspection?
Under SB 721: a California-licensed architect, a licensed civil or structural engineer, or a qualified building contractor with the appropriate license. Under SB 326: a California-licensed structural engineer or architect only (no contractor option). Section 604 follows the City's qualification standards. Whatever the framework, choose an inspector with documented experience in the housing stock that applies to your property, whether Victorian, Edwardian, mid-century stucco, condominium podium, or otherwise.
What does an EEE inspection typically look at?
The inspector evaluates the load-bearing components of exterior elevated elements: structural framing, joists, ledgers, posts, fasteners, waterproofing, flashing, and any concealed wood elements that support the deck or balcony. The most common findings in older San Francisco and Marin housing stock are dry rot in concealed framing, compromised flashing at the ledger, and deferred painting that has allowed moisture into the wood. Findings are categorized by severity; under SB 721, repairs are generally required within 120 days of the report, with emergency hazards addressed immediately.
How much does the inspection cost?
Cost varies by building size, number of elevated elements, complexity, and access. A small 3-unit or 4-unit building with two or three balconies and a wooden walkway typically falls in a several-thousand-dollar range. Larger buildings, more elements, and complex access can scale higher. Repair scope, if any findings, is separate. For HOAs, the inspection cost is typically funded through the operating budget or a special assessment, with the longer-term capital plan rolling into the reserve study.
I am planning to sell. Should I do the inspection before listing or after I accept an offer?
Before listing. Completing the inspection and any required repairs up front lets the report and clearance go into the disclosure package on day one. Buyers see a property where the homework is done, and the seller avoids the late-stage negotiation that comes when a buyer surfaces the question mid-contract. The pattern that converts is a complete, organized, frontloaded package. The pattern that creates problems is a "we'll deal with it during escrow" posture.
I own a 3-unit or 4-unit building in San Francisco. What is the right first step?
Schedule the inspection. If a sale is on the radar, the right starting point is also a valuation conversation: what the building is worth in today's market, what the timeline to a clean listing looks like, and how the compliance work sequences against the rest of the pre-sale prep. Request a free home valuation or book a 15-minute call to map it out.
Selling a multi-unit building or HOA-governed condo in SF or Marin?
A complete EEE inspection package is one of the cleanest pieces of pre-sale prep for any multi-unit property in San Francisco or Marin. Whether you own a 3-unit Victorian, a 4-unit walk-up, or a small condo inside an HOA, the timing and sequencing of the inspection against your listing date matter. Start with a real number on your property's current value.
