For renovations of mixed-use buildings (street-level retail with apartments above), what are viable compliance paths for fire separation, egress, and sprinklers without full gut?

Instead of tearing everything down, you can usually just renovate your building to meet the current codes by:
- Making walls and ceilings stronger to prevent fires.
- Making exits better without doing a ton of construction.
- Putting in just a few sprinklers or alarms where needed.
- Taking advantage of existing-building codes for more wiggle room.
It really helps to have an architect or engineer who knows the codes inside and out. They can help you figure out the cheapest and most legit way to get your building up to snuff.

In mixed-use renovations, viable paths often include upgrading existing fire-rated assemblies with tested overlays, adding rated doors and penetrations seals, improving egress lighting and signage, and extending sprinklers or using NFPA-approved alternatives allowing code compliance without a full gut while preserving existing structure and finishes.
Renovating mixed-use buildings with street-level retail and apartments above requires careful consideration of fire safety regulations. Here are some viable compliance paths for fire separation, egress, and sprinklers without full gut renovations:
Fire Separation
Fire-Resistant Walls: Use materials like 5/8" Type X gypsum board or equivalent to achieve a 1-hour fire-resistance rating. Ensure walls are continuous from the foundation to the roof.
Egress
Separate Exits: Provide separate exits for residential and commercial areas, with clear signage and illumination.
Sprinklers
NFPA 13R or NFPA 13: Install sprinkler systems in accordance with NFPA 13R or NFPA 13 standards, depending on the building’s size and occupancy.

Upgrade fire separations with rated assemblies or coatings, retrofit egress with selective stair/corridor improvements, and install flexible or partial sprinkler systems using code alternatives to avoid a full gut.
