If you're a building owner, HOA board member, or property management company, you bear the consequences of how a building performs without having designed it or built it. The water intrusion that's damaging tenant units. The balcony inspection that's now legally required. The deferred maintenance that's compounding into a capital problem. The leak that three previous contractors couldn't fix. All of it lands on your desk, your board agenda, and your operating budget.
ACE Building Envelope Design serves three related segments under this audience. Commercial building owners and operators — owners of factories, hotels, retail centers, office buildings, and mixed-use commercial assets — engage ACE for conditions assessments, leak investigation, and remediation design on aging or troubled envelopes. HOAs (homeowner associations) — primarily condominium boards in California — engage ACE for SB 326 mandatory balcony inspections, post-construction CD support, and envelope-specific reserve study input. Property management companies — firms managing apartment portfolios, mixed-use buildings, and commercial assets on behalf of owners — engage ACE as the technical partner who diagnoses chronic envelope problems and produces remediation specifications that contractors can bid against.
SB 326 / SB 721 Compliance Deadline
California's first compliance deadline for both mandatory balcony inspection statutes was January 1, 2025 — and recurring inspection cycles continue. HOAs and apartment owners that haven't completed inspections face liability exposure if balcony failures occur. ACE performs inspections under both mandates with reports that meet statutory requirements.
SB 326: Mandatory Balcony Inspections for HOAs
California Senate Bill 326 requires condominium associations (HOAs) to inspect elevated exterior elements — balconies, decks, walkways, stairways, and similar load-bearing components — every 9 years. The first inspection cycle had a deadline of January 1, 2025, and subsequent cycles run on a rolling 9-year basis. The inspection must be performed by a licensed architect or structural engineer, and reports must be submitted to the HOA board and incorporated into the association's official records.
For an HOA board, SB 326 creates compliance pressure on a fixed timeline. Failure to complete required inspections exposes the association to legal liability if a balcony or elevated element fails between inspection cycles. ACE's SB 326 inspection process is structured around the statute's requirements: licensed inspector, statistically significant sample of load-bearing waterproofing components, written report with prioritized findings, board-ready documentation that becomes part of the association's official record. The official statute language defines the technical scope; ACE's inspection teams know how to apply it efficiently.
SB 721: Mandatory Inspections for Apartment Buildings
California Senate Bill 721 applies to apartment buildings with three or more multifamily dwelling units. It mirrors SB 326 in structure but applies to apartment buildings rather than condominiums, and the inspection cycle runs every 6 years rather than every 9. The first compliance deadline was January 1, 2025. SB 721 typically affects apartment building owners and property management companies operating apartment portfolios.
Like SB 326, SB 721 inspections must be performed by a licensed professional and produce a written report that the building owner is required to maintain. ACE performs SB 721 inspections under the same disciplined process — licensed inspectors, prioritized findings, and remediation rough-order-of-magnitude estimates that support owner capital planning. For property management companies operating portfolios across California, ACE provides streamlined SB 721 inspection programs that consolidate scheduling, documentation, and reporting across multiple buildings.
SB 326 vs. SB 721: At a Glance
| SB 326 (HOAs / Condos) | SB 721 (Apartments) | |
|---|---|---|
| Building Type | Condominium associations governed by an HOA | Apartment buildings with 3+ multifamily units |
| Inspection Cycle | Every 9 years | Every 6 years |
| First Deadline | January 1, 2025 | January 1, 2025 |
| Inspector Required | Licensed architect or structural engineer | Licensed architect, engineer, or qualified contractor |
| Report Recipient | HOA board; becomes association record | Building owner; maintained for inspection |
| Scope | Statistically significant sample of load-bearing elevated elements | All exterior elevated elements |
Remediation: Three Tiers, Realistic Budgets
When an SB 326 or SB 721 inspection identifies issues — or a conditions assessment surfaces remediation needs — owners and HOA boards need realistic cost guidance to plan and budget. ACE produces rough-order-of-magnitude (ROM) estimates at three severity tiers so the board or owner can plan for outcomes ranging from straightforward repairs to comprehensive replacement.
Localized waterproofing repairs, sealant replacement, individual flashing corrections. Lowest cost, least disruption, addresses isolated issues identified during inspection.
Multi-component remediation across multiple balconies or building areas. Includes selective demolition, weather barrier replacement, and waterproofing system rebuild on affected components.
Comprehensive envelope remediation. Full replacement of balcony waterproofing systems, deck-to-wall transitions, and structural waterproofing. Multi-year capital project scope.

Conditions Assessments: Forensic Investigation for Real Buildings
Beyond the SB 326/SB 721 statutory inspections, ACE's Conditions Assessment service supports owners and property managers dealing with active envelope problems on existing buildings. Mystery water intrusion. Persistent leaks that previous contractors couldn't fix. Concealed moisture damage discovered during interior renovation. Pre-acquisition envelope due diligence on a building under contract. Reserve study support that goes deeper than a generic component-life table.
What makes ACE's conditions assessment different is its forensic investigation methodology. We don't just walk a building and document obvious problems. We use moisture mapping, infrared thermography, electronic leak detection, and selective destructive testing to identify the root cause of envelope failures — not just the symptoms. The remediation designs we produce address the actual failure mechanism, which means contractors can bid against a defined scope and the repair holds for the remaining life of the building rather than failing again two years later. The National Institute of Building Sciences publishes guidelines on building enclosure conditions assessment that align with ACE's methodology.
What Keeps Property Owners Awake at Night
Every concern we hear from building owners, HOA boards, and property managers traces back to one of these risks. ACE's services address each directly.
Compliance Liability
SB 326/SB 721 deadlines passed without inspection. If a balcony fails between inspection cycles and the HOA hasn't complied, the legal exposure can be catastrophic for the association.
Mystery Water Intrusion
Persistent leaks that three previous contractors couldn't diagnose. Repeated repair attempts that fail. Tenant complaints that won't stop. Insurance claims that compound.
Reserve Fund Inadequacy
Discovering during a major envelope event that the reserve fund was based on optimistic component-life assumptions and the actual remediation cost is 3x the budgeted amount.
Pre-Acquisition Surprises
Buying a building based on a generic property condition assessment, then discovering envelope problems during renovation that weren't disclosed and weren't priced into the deal.
How ACE's Service Pillars Serve Building Owners and HOAs
Conditions Assessments (incl. SB 326/SB 721)
The primary service for this audience. Statutory balcony inspections, forensic leak investigation, comprehensive envelope assessment, and remediation design.
Remediation Design (AOR)
For major remediation projects, ACE produces stamped repair drawings and specifications that contractors bid against — eliminating scope ambiguity and bid variance.
Remediation Construction Administration
Field oversight during the remediation construction phase — ensuring the repair installs correctly the first time and the documentation supports the warranty position.
Window Testing (FGIA Accredited)
Post-remediation testing to verify the repair performs as designed — protecting the owner's warranty position and providing documented evidence of envelope integrity.
Frequently Asked Questions
SB 326 applies to condominium associations (HOAs) — it requires inspection of elevated exterior elements every 9 years, with the first deadline of January 1, 2025. SB 721 applies to apartment buildings with three or more units — it requires inspection every 6 years, with the same first deadline. ACE performs inspections under both mandates.
A licensed inspector examines a statistically significant sample of load-bearing components and waterproofing on elevated exterior elements. The inspection produces a written report identifying conditions, prioritizing repairs by severity, and documenting components that fail to meet structural or waterproofing performance. Reports are submitted to the HOA board and become part of the association's official record.
Forensic-level investigation. We start with a building condition walkthrough, then progressively narrow the source using moisture mapping, infrared thermography, electronic leak detection, and selective destructive testing. Our process identifies root causes — not symptoms — and produces a remediation design that addresses the actual failure mechanism.
Cost depends on building size, complexity, and assessment scope. ACE provides fixed-fee proposals after an initial walkthrough. For HOAs, a Reserve Study-supporting envelope assessment is typically a small fraction of a full reserve study cost. For commercial owners with active leaks, forensic investigation cost is far less than the cost of repeated unsuccessful repair attempts.
Yes. For commercial real estate acquisitions where envelope condition affects deal value, ACE provides envelope-specific due diligence that goes beyond a generic property condition assessment. We identify deferred maintenance, document existing failure conditions, and produce remediation ROM estimates that support deal negotiation.
