Three Code Enforcement Trends Architects Should Prep For

The landscape of architectural compliance is undergoing a fundamental transformation. Regulatory bodies are no longer just updating standards; they are re-engineering the entire enforcement process. This shift is driven by urgent climate goals, the universal adoption of digital infrastructure, and a heightened focus on public safety and resilience. For architectural firms, staying ahead is not just about adapting to new rules but about retooling workflows for a new era of enforcement.

These trends are not isolated events. Stricter, more complex energy and safety codes are being implemented concurrently with the rollout of digital review platforms. This means that highly nuanced requirements, such as specific thermal bridging calculations or new fire protection rules for lithium-ion batteries, are now subject to the rigorous, searchable, and data-driven scrutiny of digital enforcement. An error or omission that might have been overlooked in a manual review is now easily discoverable, creating a multiplicative increase in compliance risk. Navigating this new environment requires a proactive and informed approach.

1. Stricter Energy & Sustainability Codes Are the New Baseline

The push for decarbonization has moved from a topic of discussion to a core driver of code enforcement. Jurisdictions nationwide are adopting aggressive energy codes that demand higher performance for building envelopes, mandate electrification of systems, and integrate renewable energy as a baseline requirement. This represents a definitive shift from prescriptive component requirements to holistic building performance standards.

The National Foundation: IECC Evolves

The International Energy Conservation Code (IECC) serves as the model for most states, and its recent updates signal the direction of the entire industry. The 2021 IECC delivered an approximate 9.4 percent efficiency improvement over the 2018 version.

The 2024 IECC continues this trajectory. It introduces new provisions for electric vehicle (EV) charging readiness, heat pump water heaters, and demand-response-ready HVAC systems, aligning construction with the shift toward grid-interactive, high-performance homes. The 2024 version also generally reduces lighting power allowances (LPAs) and expands control requirements, mandating demand-responsive lighting controls for buildings with a general lighting load of 4000 Watts or more. These updates reflect a clear focus on not just reducing energy consumption but also managing energy demand intelligently.

The Vanguard: How State "Stretch" Codes Predict the Future

Leading states are implementing "stretch" codes that significantly exceed IECC baselines, providing a preview of where national standards are headed. These jurisdictions are laboratories for the next generation of energy policy, and their requirements demand immediate attention.

California, for instance, continues to push the envelope. Its Title 24 (2025), effective January 1, 2026, is arguably the most aggressive code in the nation. It strongly favors electric heat pump systems over gas, expands photovoltaic (PV) system mandates, and introduces Battery Energy Storage System (BESS) readiness for many new nonresidential and multifamily projects. The influence of Title 24 extends far beyond state lines, with national developers applying its standards across their portfolios to maintain design consistency and future-proof their buildings.

In the Pacific Northwest, the Washington State Energy Code (2021), which took effect March 15, 2024, uses a credit-based system to heavily incentivize electric heat pumps for both space and water heating. Projects using combustible fuels like natural gas must obtain more energy credits to comply, making electrification the clear and simpler pathway.

Meanwhile, the NYC Energy Conservation Code (2025) is aligning with the stringent NYStretch Energy Code and implementing a suite of local laws for rapid decarbonization. Local Law 154, the "All-Electric Law," effectively phases out fossil fuels in new construction. On top of that, Local Law 88 mandates significant lighting upgrades in all commercial buildings over 25,000 square feet by January 1, 2025.

And in New England, the Massachusetts Stretch Code (2023), effective since July 1, 2023, introduces innovative compliance pathways like the Thermal Energy Demand Intensity (TEDI) target. This approach focuses on minimizing a building's heating demand through a high-performance envelope and advanced heat recovery systems. The code also features some of the nation's most stringent EV-ready requirements, mandating that 20% of parking spaces in most new commercial and multifamily buildings are wired for future EV charging.

The increasing upfront cost of compliance with these advanced codes is creating a new economic reality. While measures like superior insulation, heat pump systems, and solar readiness increase initial construction costs, they simultaneously create a "resilience dividend". Buildings that comply are future-proofed against volatile energy prices and stricter future regulations, making them more valuable long-term assets. The architect's role must now expand to that of a strategic advisor, articulating how the "extra" cost of compliance is a critical investment that protects the asset's future value and reduces operational risk.

Actionable Strategy for Architects

To navigate this complex environment, firms should run early energy and envelope pre-checks before schematic design is locked. Add a dedicated summary sheet in the construction documents that explicitly lists insulation values, glazing U-factors, HVAC efficiencies, and controls, citing the relevant code sections. This proactive documentation demonstrates clear compliance and streamlines the review process.

2. Digital Permit & Plan Review Adoption Is Now Default

The era of paper-based plan submittals is over. Municipalities across the country have standardized on digital ePlan review portals, making proficiency in digital documentation a non-negotiable skill for architects. This is not merely a media shift; it introduces a new layer of technical requirements for file formatting, naming conventions, and data integrity that directly impacts submission success and project timelines.

The Technology Stack: Platforms and Requirements

Cities, such as San Diego, Palo Alto, Chicago, and Irvine, are widely using platforms like Accela, ProjectDox, e-PlanSoft, and Cityworks for their electronic plan review processes.

While specific rules vary by jurisdiction, a clear set of common requirements has emerged:

• File Format and Integrity: The Portable Document Format (PDF) is the universal standard for submissions Critically, these files must be unlocked, unencrypted, and have all layers flattened. Layers, comments, or password protection can make a file unreadable by the review software, leading to immediate rejection.

• File Naming Conventions: Jurisdictions enforce strict, standardized naming conventions. These often require a precise sequence of information, such as a sequence number, sheet designation (e.g., A-101), a descriptive title, and the permit application number. An error as simple as an underscore where a dash is required can cause an automated system to reject the entire submittal.

• Sheet and Document Organization: A frequent requirement is that each drawing sheet must be saved and uploaded as a separate, individual file. All supporting documents, such as structural calculations, energy reports, and specifications, must also be uploaded as distinct files and not bundled with the plan set.

• Digital Signatures and Seals: A scanned image of a wet signature is typically not acceptable. Instead, jurisdictions require a verifiable digital signature from a licensed professional, authenticated by a third-party certification authority like GeoTrust or Verisign. The digital signature must be applied as the final step, after the professional's seal image and any required text have been flattened into the document.

  
  

This shift to digital review fundamentally changes the nature of a plan set. It is no longer just a collection of drawings; it is a structured database of information. The file names, sheet numbers, bookmarks, and searchable text are all metadata that the review system uses to parse, route, and analyze the project. A failure in the "data," such as a wrong file name, is now as critical as a failure in the "drawing," such as a wrong dimension. Review systems automatically version files based on identical naming; a typo in a revised sheet name creates a duplicate file, causing confusion and delays. Architects must now think like data managers. The organization and formatting of the digital package are part of the design deliverable itself.

Actionable Strategy for Architects

Establish a firm-wide standard for digital submittals that anticipates these requirements. Standardize sheet naming conventions internally (e.g., A101, S201, M301) to align with common jurisdictional rules. Develop a pre-submission checklist that includes embedding bookmarks, flattening all layers, and exporting to a text-searchable PDF/A format. Maintain a clean and organized "Submittal Docs" folder for each project containing a cover letter, a sheet index, and a log of responses to reviewer comments to ensure consistency and efficiency.

3. Increased Safety & Resilience Standards Demand Deeper Scrutiny

The definition of building safety is expanding rapidly. Beyond traditional fire egress, codes are placing greater emphasis on comprehensive accessibility, structural resilience against extreme weather and seismic events, and safety measures for new technologies. This requires architects to integrate a more diverse and stringent set of life safety standards from the earliest stages of design.

Life Safety and Egress (IBC Chapters 9 & 10)

The International Building Code (IBC) continues to evolve to address modern building risks. The 2024 IBC introduces significant updates that architects must master:

• Chapter 9 (Fire Protection and Life Safety Systems): This chapter now includes specific requirements for facilities with lithium-ion or lithium metal battery storage, reflecting a direct response to the fire risks associated with new energy technologies. This includes new rules for where automatic sprinkler systems and fire alarm systems are required in laboratories or manufacturing facilities involving these batteries.

• Chapter 10 (Means of Egress): This chapter has been substantially reorganized in the 2024 edition. It includes updated rules for headroom, new occupant load calculations for modern space types like information technology facilities, and new detailed requirements for doors in elevator lobbies and rooms with high-power electrical equipment.

• Residential Fire Safety (NFPA Standards): For residential projects, architects must be proficient in the standards set by the National Fire Protection Association. NFPA 13D governs sprinkler systems in one- and two-family dwellings, while NFPA 13R applies to low-rise multifamily residential buildings. The 2022 editions of these standards introduce new criteria for emerging building types like "tiny homes" and include updated temperature zone maps for designing freeze protection systems.

Accessibility as a Non-Negotiable Baseline (ADA & State Overlays)

Compliance with accessibility standards requires navigating multiple layers of regulation.

• Federal Baseline: The 2010 ADA Standards for Accessible Design remain the federal law, setting the minimum requirements for new construction and alterations across all areas, from accessible routes and parking to restrooms and communication elements.

• State-Specific Overlays: Many states have their own accessibility codes that are often stricter than the federal baseline. California's Building Code (CBC) is a prime example, with Chapter 11A providing detailed requirements for housing accessibility in multifamily dwellings and Chapter 11B covering public buildings, public accommodations, and commercial facilities. Architects must ensure compliance with the most stringent applicable rule. The 2025 CBC updates are expected to continue this trend of enhanced requirements.

  
  

The increasing complexity and overlapping nature of these safety and accessibility codes mean that simply designing a compliant building is no longer sufficient. Architects must now also design a compliant set of documents that proves compliance in an easily verifiable way. This "documentation burden" is becoming a distinct, critical phase of the design process. A plan reviewer using digital tools must be able to quickly find explicit proof that requirements from the ADA, IBC, and local codes have all been met. If that proof is buried across dozens of sheets and notes, the review will take longer and is more likely to result in questions and rejections.

Actionable Strategy for Architects

Proactively document compliance by creating a dedicated "Egress and Accessibility Data" key sheet in every plan set. This sheet should explicitly call out occupant loads, exit counts and widths, common ADA dimensions like turning radii and reach ranges, and key mounting heights. Crucially, it should include direct citations to the relevant code sections (e.g., "IBC 1006.2," "2010 ADA 404.2.3," "CBC 11B-604.5"). This preempts reviewer questions, demonstrates thoroughness, and dramatically streamlines the verification process.

Don't Just Adapt. Dominate.

The convergence of stricter codes, digital enforcement, and heightened safety standards isn't just a challenge; it's a filter that will separate the firms that cling to outdated workflows from those that embrace the future. Manual checks and last-minute fixes hinder ability to outpace competition, and serve as a potential thread to timelines, budgets, and reputation. The future of architecture belongs to firms that build compliance into their process from the very first line drawn.
