Building Safe, Code-Compliant Multifamily Developments

Safety and fire protection are non-negotiable in multifamily construction. A well-designed building must protect residents, first responders, and property assets in the event of an emergency. Without proper planning, a fire or safety hazard can result in severe property damage, legal liability, and loss of life.

Modern building codes and safety regulations have evolved significantly to improve fire resistance, suppression, and evacuation strategies, but compliance alone is not enough. A truly safe multifamily development requires a proactive approach, integrating fire-resistant materials, advanced suppression systems, emergency egress planning, and modern detection technology.

At KennMar Construction, we take a comprehensive, code-driven approach to safety—ensuring our projects meet or exceed fire codes, life safety standards, and structural resilience. Through strategic material selection, integrated fire suppression, and proactive emergency planning, we help multifamily developers reduce risks and create secure, high-performing living environments for residents.

1. Fire-Resistant Materials & Construction Methods

The first line of defense against fire is building with fire-resistant materials that slow the spread of flames, contain smoke, and maintain structural integrity under extreme conditions. Selecting the right materials at the outset of a project can reduce fire risk, extend evacuation time, and improve overall tenant safety while also helping developers meet stringent building codes.

Challenges in Fire-Resistant Construction:

Flammable building materials increasing fire risk and insurance costs.
Insufficient fire-rated barriers allowing fire and smoke to spread between units.
Varying code requirements across jurisdictions affecting material specifications and fire ratings.

KennMar Construction’s Approach:

Fire-rated gypsum board, concrete, and treated wood to contain fire and prevent rapid spread.
Two-hour rated walls and ceilings between units to improve containment and extend evacuation time.
Intumescent coatings on steel structures to prevent premature failure in high-heat conditions.

Using fire-resistant materials throughout the building envelope and interior partitions not only enhances occupant safety but also minimizes structural damage, allowing for faster recovery and reduced rebuilding costs after a fire event.

2. Fire Suppression & Sprinkler Systems

A properly designed fire suppression system is critical in preventing fire from spreading and causing catastrophic damage. Sprinklers are proven to control or extinguish flames before they can endanger lives and property, making them an essential component of modern multifamily developments.

However, not all sprinkler systems are created equal. The type of system used must be carefully selected based on building height, climate conditions, and local fire codes. Without careful planning, a suppression system could be ineffective, require costly modifications, or fail to provide full coverage in critical areas.

Fire Suppression Challenges in Multifamily Construction:

Meeting NFPA (National Fire Protection Association) and local codes while balancing cost and system effectiveness.
Ensuring adequate water pressure and sprinkler head coverage throughout the building.
Preventing pipe freezing in colder climates where water-based systems could be compromised.

KennMar Construction’s Approach:

Wet-pipe sprinkler systems for cost-effective, reliable fire suppression in conditioned areas.
Dry-pipe and pre-action systems for parking garages and unconditioned spaces where freezing is a concern.
Standpipe and fire pump installations to ensure consistent water pressure across all floors.

By implementing high-performance fire suppression systems, we ensure that fires are controlled quickly and effectively, limiting risk to occupants and property.

3. Smoke Control & Ventilation Strategies

Fires don’t just create flames—they fill buildings with thick, toxic smoke that can make evacuation nearly impossible. Many fire-related fatalities result from smoke inhalation rather than direct burns, making effective smoke control systems critical for resident safety.

Multifamily buildings require dedicated ventilation and smoke exhaust strategies that clear common areas, protect stairwells, and allow occupants to exit safely. Properly integrated smoke control systems improve evacuation efficiency and also help firefighters contain and suppress fires more effectively.

Challenges in Smoke Management:

Rapid smoke buildup in hallways and stairwells creating dangerous conditions.
Lack of pressurization in stairwells and elevators allowing smoke infiltration.
Exhaust system design flaws that spread smoke rather than contain it.

KennMar Construction’s Approach:

Pressurized stairwells and elevator shafts to create smoke-free escape routes.
Automatic smoke exhaust fans and dampers to clear hallways and corridors.
Fire-rated ventilation ductwork and compartmentalization to prevent smoke migration between units.

By prioritizing effective smoke control, we ensure safer evacuations and reduced fire-related injuries in multifamily developments.

4. Exit & Emergency Egress Planning

Even the best fire prevention systems cannot eliminate all risks, which is why a well-designed evacuation plan is essential for protecting residents during an emergency.

Multifamily developments must include clearly marked, unobstructed exit routes that provide safe, fast, and ADA-accessible pathways for all occupants. Inadequate egress planning can lead to dangerous bottlenecks, panic, and increased risk of injury in an emergency.

Egress & Exit Planning Challenges:

Poorly placed or insufficient stairwells leading to evacuation congestion.
Failure to meet ADA accessibility requirements for emergency exits.
Lack of emergency lighting and wayfinding signage in smoke-filled conditions.

KennMar Construction’s Approach:

Multiple, well-distributed stairwell exits to ensure fast evacuation.
Photoluminescent exit signage and backup emergency lighting for low-visibility conditions.
Code-compliant, ADA-accessible egress routes ensuring all residents can evacuate safely.

Through strategic egress planning, signage placement, and stairwell design, we create buildings that are safer for both residents and first responders.

5. Smart Fire Detection & Alarm Systems

Modern fire safety isn’t just about suppression—it requires intelligent detection and alert systems to provide early warnings, improve response times, and minimize fire damage.

Challenges in Fire Detection & Alarm Systems:

False alarms leading to complacency or unnecessary evacuations.
Delayed response times due to outdated or disconnected systems.
Lack of integration with building automation and security systems.

KennMar Construction’s Approach:

Networked fire alarms with real-time monitoring to alert building management and emergency responders instantly.
Smart smoke and CO2 detectors that reduce false alarms while improving detection accuracy.
Integration with security and building management systems for centralized emergency response.

By incorporating modern fire detection and alarm technology, we help developers ensure early warnings and improved safety protocols in multifamily buildings.

The KennMar Advantage

At KennMar Construction, we believe that fire safety is not just about compliance—it’s about creating resilient, well-protected communities. By integrating fire-resistant materials, advanced suppression systems, emergency egress planning, and smart detection technologies, we ensure that multifamily developments meet the highest safety standards.
