Codes and Standards Update for Home Builders: February Policy Shifts, Smart Energy, and Market Trends

Staying current with building codes, regulatory shifts, and emerging standards is essential for home builders who want to deliver safe, efficient, and market-responsive homes. The February landscape brings developments across technology platforms that streamline construction management, demographic changes that reshape housing demand, smart energy innovations that challenge traditional grid assumptions, and ongoing tension between historic preservation rules and modern energy performance goals. Each of these areas carries implications for how builders approach design, permitting, compliance, and construction. This building codes and standards update examines the key shifts that professional builders should track as they plan projects for the coming months.

Technology Platforms Reshape Building Lifecycle Management

The construction technology sector continues to deliver tools that promise to streamline how builders manage projects from design through handover. A major launch in this space comes from Katerra, which introduced a suite of technology products targeting the entire lifecycle of the building process. The proprietary software platform integrates data gathered across the construction supply chain and the building process itself, offering builders a unified view of project operations.

Apollo Construct: Project Management and Estimation

The first application in the suite, Apollo Construct, serves as a project management tool covering estimation and scheduling. For builders, this means having cost projections and timeline data in a single environment, reducing the friction that typically occurs when estimators and project managers work from separate systems. The ability to link material costs directly to schedule milestones helps builders identify budget risks earlier in the construction process.

Apollo Insight and Apollo Connect: Design and Budget Integration

Two additional modules round out the platform. Apollo Insight incorporates visual 3D design feasibility studies, allowing builders and architects to evaluate design options before committing to construction documents. Apollo Connect brings BIM-based budgeting tools into the workflow, making it easier to align design decisions with real-time cost data.

Katerra has built these products using open API integration, meaning the platform can connect with tools already in use across construction workflows. For builders who have invested in existing software ecosystems, this approach reduces the barrier to adoption and avoids the need to rip and replace established systems.

The Building Platforms System

Beyond software, Katerra also announced its Building Platforms system, a method for designing buildings as manufactured, repeatable products while still maintaining design configuration options for various clients, regions, and markets. This concept aligns with broader industry trends toward standardization and prefabrication, which help builders control quality and reduce on-site variability. As recent building codes and standards reshape residential construction, technology platforms that support repeatable, code-compliant designs become increasingly valuable for production builders.

Demographic Trends Reshape Housing Demand and Development Standards

Shifts in who rents, where they rent, and why they rent carry direct implications for building codes and development standards. The fastest-growing segment of the rental population is now households earning six-figure incomes, a trend that challenges traditional assumptions about the rental market and what it demands from builders.

The Growth of High-Income Renters

According to a study by Apartment List, the number of households earning six figures and choosing to rent has grown 48 percent over the past decade. Multi-family construction has quadrupled since 2010 and now exceeds pre-recession levels, with most of the activity concentrated on the high end of the market.

Several factors drive this shift:

• High earners increasingly value the flexibility that renting provides, particularly in urban job markets where career mobility is common.
• The high cost of purchasing a home in major metropolitan areas locks many well-compensated professionals out of home ownership despite their income levels.
• Student loan debt and stricter lending standards create additional barriers to home ownership even for those who could technically afford a mortgage.
• Proximity to high-paying jobs in city centers makes renting near downtown more attractive than commuting from more affordable suburban neighborhoods.

Regional Variations and Market Implications

The rise of high-income renters has been most dramatic in mid-size, growing metropolitan areas, particularly Denver, Austin, and Oklahoma City. Growth in this category has been slower in the largest and most expensive markets such as New York, Los Angeles, and San Francisco, where the rental market was already heavily concentrated at the high end.

For builders, this demographic shift suggests several strategic considerations:

1. Multi-family projects targeting upper-income renters should include amenities and finishes that compete with for-sale product, since these tenants have the financial capacity to buy but choose not to.
2. Development standards in mid-size metros may need to evolve to accommodate higher-density rental construction in areas previously zoned for single-family or low-density development.
3. Building codes governing multi-family construction, including fire safety, sound transmission, and energy performance, become more relevant as this segment grows as a share of overall housing starts.

Smart Energy Systems Help Builders Overcome the Solar Duck Curve

One of the persistent challenges in residential solar energy has been the mismatch between when solar panels produce electricity and when homes actually need it. Arizona-based Mandalay Homes addressed this with its iON Series, a set of smart energy features that combines a well-insulated building shell, high-efficiency heating and cooling systems, and on-site solar with battery storage.

Understanding the Duck Curve

The duck curve describes the imbalance between energy supply and demand that occurs because daily peak electricity demand happens in the late afternoon and evening, while peak solar energy production occurs closer to midday. The electric grid has historically lacked the ability to store excess electricity from renewable sources for use during peak demand periods. This mismatch has created challenges for utilities and builders alike, particularly in regions with high solar adoption rates.

How the iON Series Addresses the Challenge

The iON Series optimizes energy collection, storage, and management to overcome the duck curve. By storing energy from peak production periods onsite in battery systems, the home can draw on its own stored power during evening peak hours rather than pulling from the grid. This approach offers several benefits:

• Reduced strain on the electric grid during peak demand periods, which helps utilities avoid costly infrastructure upgrades.
• Lower energy costs for homeowners, who can use stored solar power instead of purchasing grid electricity at peak pricing rates.
• Improved energy resilience, as homes with battery storage can maintain essential loads during grid outages.
• Accelerated compliance with increasingly stringent energy codes that push toward net-zero performance.

For builders, integrating smart energy systems like the iON Series into standard offerings represents a forward-looking approach to energy code compliance. Many jurisdictions are adopting versions of the International Energy Conservation Code that require or incentivize on-site renewable energy and storage capacity. Builders who develop expertise in these systems now will be better positioned as carbon neutral targets and energy standards reshape home building requirements.

The Tension Between Historic Preservation and Modern Energy Codes

As cities push toward energy efficiency and renewable energy adoption, conflicts between historic district regulations and modern energy systems have become increasingly common. A case in Portland, Maine, illustrates the practical challenges builders and homeowners face when preservation rules and energy goals collide.

The Portland Case Study

Portland, Maine, like many historic cities, maintains district regulations that govern the appearance of homes more than 100 years old. These rules include sightline requirements for solar panels and mandates to preserve antique windows. While these regulations serve legitimate preservation goals, they can create significant barriers to energy retrofits.

One Portland homeowner who installed solar panels on his three-story, flat-roofed building found that historic district rules required the panels to be installed at a very low angle, approximately 7 degrees. At this angle, the space between the panels and the roof collects snow that may not melt until spring, leaving the panels covered and unable to produce energy during much of the winter. The result is a solar installation that satisfies the letter of the historic district regulations but delivers far less energy performance than an optimally angled system would.

Broader Implications for Builders

This tension between preservation and energy performance is not unique to Portland. Builders working in historic districts or near designated landmarks should be aware of several considerations:

• Solar panel placement and angle restrictions can dramatically reduce system output, making it harder to meet energy code requirements or net-zero targets.
• Window replacement restrictions may force builders to pursue expensive restoration or interior storm window solutions instead of modern high-performance glazing.
• Preservation review processes can add months to project timelines, affecting construction schedules and carrying costs.
• Some jurisdictions are beginning to amend historic district rules to accommodate renewable energy systems while still preserving historic character, creating a patchwork of regulations that varies by location.

At the same time, cities are also grappling with pedestrian and bicycle safety standards that affect how streets and neighborhoods are designed. Since 2010, cyclist fatalities have increased by 25 percent and pedestrian deaths have increased by 45 percent across the United States. Several measures could reduce these numbers, including reducing the height of front bumpers on vehicles, implementing speed limit reductions, installing traffic calming measures, and providing better education for all road users. For builders, these trends influence site design standards, particularly in walkable communities and transit-oriented developments where pedestrian and bicycle infrastructure is a priority. Builders should also keep track of seismic, flood, wildfire, and energy code updates that affect structural design and site planning across different regions.

Looking Ahead

The February codes and standards landscape reveals a construction industry in transition. Technology platforms are making building lifecycle management more integrated and data-driven. Demographic shifts are pushing builders to reconsider what rental housing looks like and where it belongs. Smart energy systems are offering practical solutions to previously intractable grid integration challenges. And the ongoing negotiation between historic preservation and energy performance is creating both obstacles and opportunities for builders who work in established neighborhoods.

For builders who track these developments and adapt their practices accordingly, the evolving regulatory environment represents not just a compliance burden but a competitive advantage. Builders who understand the trends shaping codes and standards can design homes that meet today’s requirements while anticipating tomorrow’s expectations. Understanding the full scope of essential building codes and standards updates helps builders stay ahead of regulatory changes and deliver homes that perform better, last longer, and satisfy increasingly sophisticated buyers.
