If you own a San Diego apartment building with three or more units and any wood-supported balconies, decks, stairways, or elevated walkways, California's SB 721 required you to have those elements professionally inspected by January 1, 2026 — a deadline that has now passed. Owners who haven't completed the inspection are out of compliance and may be subject to enforcement actions, including daily fines of $100 to $500 depending on local enforcement.
SB 721 — the "Balcony Inspection Law" — was enacted after the 2015 Berkeley balcony collapse that killed six people. It requires periodic inspection of exterior elevated elements on multifamily rental buildings so structural decay is caught before it becomes a tragedy. This guide explains exactly what the law requires, who it applies to, what the deadlines and penalties are, and what a San Diego owner should do now. RMG provides flat-fee San Diego property management, including compliance coordination for multifamily owners.
One distinction up front, because it is the most common point of confusion: SB 721 governs rental apartment buildings. Condominiums and HOA-governed buildings follow a different law, SB 326. If your building is a condo association, this guide is not your law — see SB 326 instead.
Who This Guide Is For
This guide is written for:
- Owners of San Diego apartment buildings with 3 or more units
- Multifamily owners with wood-framed balconies, decks, stairways, or walkways
- Owners who missed the January 1, 2026 deadline and need to know their exposure
- Buyers performing due diligence on a multifamily purchase
This guide is not for:
- Condominium / HOA buildings — those follow SB 326, a separate law
- Single-family homes and duplexes (under 3 units)
- Buildings with only concrete or steel elements and no wood-based support
SB 721 Quick Answers
What is SB 721? A California law requiring owners of multifamily rental buildings with three or more units to have their wood-supported exterior elevated elements — balconies, decks, stairways, walkways — inspected by a licensed professional, then re-inspected every six years. It is codified in Health and Safety Code §17973.
What was the SB 721 deadline? January 1, 2026. The original January 1, 2025 deadline was extended by one year through AB 2579. That deadline has now passed — uninspected buildings are in non-compliance.
How often are re-inspections required? Every six years after the first inspection.
Who can perform the inspection? A licensed architect, a licensed civil or structural engineer, or a contractor holding an A, B, or C-5 license with at least five years of relevant experience. The inspector must review at least 15% of each type of elevated element.
What are the penalties for non-compliance? Local building officials may impose fines of $100 to $500 per day until the inspection is completed and hazards resolved, and non-compliance can jeopardize insurance coverage and create liability exposure.
Does SB 721 apply to condos? No. Condominiums and HOA buildings are governed by SB 326, which has different deadlines and a nine-year cycle. SB 721 is for rental apartments.
Does SB 721 Apply to My Building?
Yes, if all of these are true: the building is a rental (not a condo/HOA), it has three or more dwelling units, and it has "exterior elevated elements" — balconies, decks, porches, stairways, walkways, or entry structures — that are more than six feet above ground and rely in whole or substantial part on wood or wood-based products for support.
No, if: the building is a condominium or HOA-governed (that's SB 326), it has fewer than three units, or its elevated elements are entirely concrete or steel with no wood-based structural support.
New construction note: buildings that received their certificate of occupancy on or after January 1, 2019 are inspected within six years of that certificate — not by the general January 1, 2026 deadline.
SB 721 vs. SB 326: Which Law Applies to You?
California has two balcony-inspection laws for the same safety issue, split by ownership structure. Confusing them is the most common SB 721 mistake — here is the side-by-side.
SB 721 — Rental Apartments
Applies to: multifamily rental buildings with 3 or more units
Inspection cycle: every 6 years
First deadline: January 1, 2026 (extended from 2025 by AB 2579)
Inspectors: architect, civil/structural engineer, or A/B/C-5 contractor (5+ yrs)
Sampling: at least 15% of each element type
SB 326 — Condos / HOAs
Applies to: condominiums and common-interest developments (HOA-governed)
Inspection cycle: every 9 years
First deadline: January 1, 2025
Inspectors: licensed structural engineers or architects only (narrower pool)
Sampling: statistically significant sample (95% confidence)
The simple test: if you own the building and rent the units, it's SB 721. If individual units are owned and there's an HOA, it's SB 326.
The Deadline Has Passed — What That Means Now
The first SB 721 inspection was due January 1, 2025, then extended one year to January 1, 2026 by AB 2579. As of mid-2026, that deadline is behind us. If your building qualifies and has not been inspected, you are no longer "getting ready" — you are non-compliant, and the practical consequences are already live.
Daily fines. Local code enforcement can impose $100–$500 per day until you complete the inspection and resolve any hazards.
Insurance exposure. Carriers increasingly treat inspection compliance as an underwriting requirement. A balcony-related claim on an uninspected building can be denied, and non-compliance can affect renewal.
Liability. If someone is injured by a failed element on a building you never inspected, the missing inspection becomes central evidence — potentially negligence per se.
The fix is to act now, not wait. Completing the inspection stops the clock on accruing fines and restores your standing. Late is far better than never.
What Happens If You Ignore SB 721?
If you're reading this because you missed the deadline and want to know how much trouble you're actually in — here is the honest answer. The consequences aren't just a fine. They surface at the moments that matter most: when you insure, refinance, sell, or have an accident.
Code enforcement & fines. Local building officials can issue violations and, depending on the jurisdiction's enforcement practice, assess fines of $100–$500 per day until you inspect and resolve hazards. Enforcement timing varies by city — some act on complaint, some proactively — but the exposure exists the moment the deadline passes.
Insurance denial or non-renewal. This is the one that bites quietly. Carriers increasingly treat SB 721 compliance as an underwriting condition. An uninspected building can face a balcony-claim denial, a coverage exclusion, or non-renewal — and a water-intrusion or collapse claim with no inspection file is exactly what an adjuster looks for to deny.
Refinancing & lender due diligence. Lenders and their underwriters increasingly ask for compliance documentation on multifamily loans. A missing SB 721 report can stall or complicate a refinance at precisely the wrong moment.
Selling & escrow. Buyers' agents and escrow on a multifamily transaction will ask whether SB 721 was completed. Missing it can become a price-negotiation lever, a contingency, or a closing delay — a sophisticated buyer treats an uninspected building as deferred-liability they'll discount for.
Personal-injury liability. The worst case. If a balcony or stairway fails and injures someone on a building you never inspected, the missing inspection becomes central evidence — potentially negligence per se. SB 721 exists because six people died in Berkeley; the liability exposure for ignoring it is real, not theoretical.
The reassuring part: every one of these consequences is closed off by completing the inspection. You can't change that you're past the deadline, but you can stop the exposure today — an inspection now is far better than waiting for the insurer, lender, buyer, or court to find the gap for you.
The SB 721 Compliance Process, Step by Step
1. Hire a qualified inspector
A licensed architect, civil/structural engineer, or A/B/C-5 contractor (5+ years' experience). Confirm the license is active and that they have no tie to a repair contractor — the inspector cannot perform the repairs they recommend.
2. Inspection & sampling
The inspector evaluates at least 15% of each type of elevated element for structural integrity, water intrusion, decay, and waterproofing, and documents conditions with photos.
3. Receive the report
The inspector delivers a written report. If any condition is an immediate life-safety threat, the inspector must notify you and the local building official within 15 days.
4. Make required repairs
For non-emergency repairs: apply for a permit within 120 days of the report, and complete the work within 120 days of permit approval. A licensed contractor (not the inspector) does the work.
5. Retain records & calendar the next cycle
Keep the report for two inspection cycles (local officials can request it), and schedule the next inspection six years out.
How Much Does an SB 721 Inspection Cost?
Inspection cost is driven mostly by how many elevated elements your building has, because the inspector must sample at least 15% of each type. There is no flat statewide price — the honest answer is "get itemized quotes" — but here is how the pricing generally scales so you can budget.
Small building (a handful of units / few balconies). The low end — fewer elements to sample means a shorter inspection.
Medium building (mid-size complex). More elements, more sampling, often some exploratory openings to check concealed framing — mid-range pricing.
Large complex. The highest inspection cost, though per-unit cost often drops with scale; large complexes may negotiate a representative-sampling plan.
What moves the price: number and type of elements, building height and access, whether destructive/exploratory testing is needed to inspect concealed wood, and the inspector's discipline (a structural engineer typically costs more than a contractor-inspector but gives a more thorough analysis on complex buildings).
Budget two separate line items. The inspection is one cost; repairs are a separate and usually larger one. If the inspection finds deficiencies, repair and permit costs can range widely — from minor maintenance to five-figure structural work per element — so treat the inspection fee and a repair reserve as two distinct budget lines.
Get itemized proposals from two or three qualified, independent inspectors (ones with no tie to a repair contractor), and confirm professional liability insurance before hiring. Inspection pricing varies by building and provider — these are directional, not quotes.
What Documents Should Owners Keep?
SB 721 is, in practice, a documentation law — compliance is proven by records, and the next inspector must incorporate your prior reports. Keep a complete, retrievable file for at least two inspection cycles.
The inspection report — the full written findings, retained two cycles (12 years)
Inspection photos — the documented baseline condition of each element
Engineer / inspector report & license — proof the inspector was qualified
Permits — for any repairs requiring them
Repair invoices — from the licensed contractor who did the work
Contractor license records — verifying who performed repairs
Next inspection date — calendared six years out, so the cycle never lapses
What This Means for San Diego Multifamily Owners
San Diego's older garden-style stock is squarely in scope. The county is full of 1960s–1980s two- and three-story apartment buildings with wood-framed balconies and exterior stair-and-walkway access — exactly the construction SB 721 targets. Neighborhoods with concentrations of this stock include North Park, Hillcrest, University Heights, Normal Heights, City Heights, Pacific Beach, and Point Loma, where mid-century and older multifamily buildings are common. If you own one of these, assume you're covered until an inspector tells you otherwise.
Coastal and older buildings carry more risk. Salt air in beach-adjacent areas like Pacific Beach and Ocean Beach, deferred maintenance, and decades-old waterproofing raise the odds an inspection finds something — which is the point of the law, and a reason not to delay.
Owner responsibility, manager coordination. The legal duty sits with the building owner, but the scheduling, tenant access notices, vendor coordination, and recordkeeping are exactly the kind of work a property manager handles. RMG coordinates SB 721 compliance for the multifamily buildings it manages as part of its maintenance services.

Frequently Asked Questions
What is the difference between SB 721 and SB 326?
SB 721 covers multifamily rental buildings with three or more units, on a six-year inspection cycle. SB 326 covers condominium and HOA-governed buildings, on a nine-year cycle. They address the same safety issue — exterior elevated elements — but apply to different ownership structures with different deadlines and inspector rules.
What was the SB 721 inspection deadline?
January 1, 2026 — extended one year from the original January 1, 2025 deadline by AB 2579 (signed September 2024). That date has passed, so any qualifying building not yet inspected is in non-compliance and should be inspected as soon as possible.
How much does an SB 721 inspection cost?
Cost varies by building size and the number of elevated elements, since the inspector must sample at least 15% of each type. Get itemized proposals from two or three qualified, independent inspectors, and confirm professional liability insurance. Treat any required repairs as a separate budget line from the inspection itself.
What happens if I found problems during the inspection?
For non-emergency issues, you have 120 days to apply for a permit and 120 days after approval to complete repairs, using a licensed contractor (not the inspector). For an immediate life-safety hazard, the inspector notifies you and the local building official within 15 days, and you must act immediately to prevent access or make emergency repairs.
How long do I keep the inspection report?
Retain it for at least two inspection cycles. Local building departments can request it during permit review or code enforcement, and the next inspector must incorporate prior reports, so keep your documentation organized and accessible.
Who is responsible for SB 721 compliance — the owner or the property manager?
The legal responsibility is the building owner's. Owners commonly delegate the coordination — scheduling, tenant access notices, vendor management, and recordkeeping — to their property manager, but the compliance duty itself remains with the owner.
SB 721 is codified in California Health and Safety Code §17973; the inspection deadline was extended to January 1, 2026 by AB 2579. SB 326 governs condominium/HOA buildings separately. This guide is general information current as of June 2026, not legal advice — consult a qualified California attorney or licensed inspector for your specific building.
