Our selection criteria: capability match for multifamily (30%), durability and maintenance (25%), IAQ and transparency (20%), value and lead times (15%), and evidence quality (10%).
The 2026 material trends that matter for multifamily
1) Low-emission certified interior materials (GREENGUARD Gold/FloorScore)
Healthier air in small apartments matters more than ever.
For paints, flooring, adhesives, and composite products, request low-emission certifications in submittals and keep the paperwork on file.
GREENGUARD Gold verifies low chemical emissions via chamber testing aligned with California’s CDPH method; see the program overview in UL’s GREENGUARD explainer (2024–2025).
For hard-surface flooring and related adhesives/underlayments, SCS Global Services’ FloorScore page (2025) outlines the VOC emissions testing used by LEED and WELL.
Pros: supports IAQ policy, simplifies compliance reviews, often minimal cost premium.
Cons: not all categories carry both labels; verify scope and product lists.
Best for: everywhere—units and amenities.
Pricing: certification itself doesn’t dictate price; expect “from” parity to modest premiums, subject to change.
2) Rigid core SPC with 20–22 mil wear layers (ASTM F3261)
SPC (stone polymer composite) holds up to move-ins, pets, and rolling loads when you specify it like a contract floor.
Anchor the product to ASTM F3261 (2025 overview) and require a wear layer of 20–22 mil (0.5–0.55 mm) with test references (ASTM F410 for wear layer thickness), plus dimensional stability (ASTM F2199) and residual indentation (ASTM F1914).
Pros: fast installs, plank replacement saves turns, high dent resistance.
Cons: acoustics need an assembly (underlayment/slab), heat limits near windows—check TDS.
Best for: living/bedroom areas in stick-built and podium projects; avoid direct radiant heat zones without manufacturer approval.
Pricing: from mid-tier LVT; 20–22 mil usually carries a modest premium, subject to change.
3) Porcelain tile with A326.3-tested DCOF and ISO 10545-7 abrasion classes
In wet zones and heavy-traffic entries, porcelain is still the benchmark.
Specify dynamic coefficient of friction testing per TCNA’s ANSI A326.3 resource (2025) and request ISO 10545-7 abrasion wear class for glazed products.
There isn’t a universal “safe” DCOF number; performance depends on texture, drainage, contaminants, and maintenance.
Pros: long service life, easy sanitization, minimal staining in matte textures.
Cons: grout care and slip-risk management require operator attention; tile setting drives schedule.
Best for: baths, laundry, kitchens, corridors.
Pricing: from value 12″×24″ lines upward; large-format and through-body options add cost, subject to change.
4) Large-format porcelain and sintered slabs (low-seam walls and counters)
Fewer seams mean faster cleaning and fewer bacteria traps.
Sintered/porcelain slabs and large-format tiles (e.g., 30″×60″ and larger) deliver stone looks with lower porosity.
Pair with manufacturer EPD/HPD where available, and coordinate handling/rigging plans with installers.
Pros: low-maintenance, consistent patterning, premium perception.
Cons: specialized fabrication/handling, higher first cost.
Best for: amenity kitchens, backsplashes, shower walls.
Pricing: from mid-high depending on thickness and brand; fabrication complexity drives variance.
5) Engineered quartz and quartzite counters (clear hardness and care expectations)
For counters, set expectations by hardness and maintenance.
Engineered quartz is durable and consistent; natural quartzite offers high hardness (quartz is ~7 on the Mohs scale) with unique veining.
Remember: Mohs values are mineral-based and rock hardness varies by composition; use them as guidance rather than absolutes.
Pros: strong scratch resistance, predictable maintenance.
Cons: resin binders in engineered quartz can discolor with extreme heat; natural stones need sealing and care.
Best for: kitchens and vanities with defined hot-pan rules and trivets.
Pricing: from mid-tier engineered slabs; natural quartzite often higher, subject to change.
6) High-pressure laminate and compact laminate to NEMA LD 3
HPL remains the workhorse for doors, casework, and worktops when specified against performance tests.
Look for conformance to NEMA LD 3 (light resistance, cleanability, stain/scratch/impact, boiling water/high-temperature). Manufacturer technical data sheets commonly cite LD 3 performance.
Pros: wide design range, cost-efficient, proven durability; compact laminate adds water resistance.
Cons: edge protection is key; avoid high-heat edges without guards.
Best for: cabinet fronts, closet systems, laundry rooms, study nooks.
Pricing: from entry to mid; compact/phenolic cores cost more, subject to change.
7) KCMA/ANSI A161.1-certified modular cabinetry
Cycle-tested cabinets reduce service tickets. Require certification to KCMA/ANSI A161.1 and verify the label on submittals—KCMA’s certification program overview (2024–2025) explains durability testing for doors, drawers, finishes, and construction.
Pros: predictable performance in rentals, easier vendor comparisons.
Cons: limited design flexibility at the lowest price tiers.
Best for: unit kitchens and baths; consider plywood boxes in wet-prone areas.
Pricing: from value modular lines; upgrades (plywood, premium hardware) add cost, subject to change.
8) PET felt acoustic panels with tested NRC assemblies
Noise drives churn. PET felt panels and baffles can reach NRC ~0.7–0.9 depending on thickness, density, and mounting.
Specify assemblies with test reports using ASTM C423 (reverberation room) and state the mounting condition and air gap. For a plain-language primer on ratings, see National Gypsum’s NRC explainer (2024).
Pros: quick upgrades for amenities, lightweight, recycled content options.
Cons: not a substitute for wall/ceiling STC assemblies; can show dirt in high-touch areas.
Best for: co-working lounges, mail rooms, fitness studios, leasing offices.
Pricing: from commodity 9–12 mm panels; custom cuts and prints add cost, subject to change.
9) Low-/zero-VOC paints and sealants with recognized ecolabels
Follow federal procurement best practice by using recognized ecolabels/specs when practical. EPA maintains the Recommendations of Specifications, Standards, and Ecolabels for Federal Purchasing (2025) and model contract language for interior latex paint.
Pros: lower odor during turns, aligns with sustainability goals.
Cons: verify coverage/hide in field mockups; not all labels cover every performance attribute.
Best for: unit interiors and corridors.
Pricing: from standard contractor-grade; low-/zero-VOC lines often at parity today, subject to change.
10) PVD-coated faucets and hardware
Color-consistent metals without quick wear: physical vapor deposition (PVD) adds a thin, hard, corrosion-resistant layer that resists scratching and tarnish better than many plated finishes. Request salt-spray, adhesion, and hardness test results in submittals.
Pros: longer finish life in rentals, cohesive palette options (brushed nickel, warm golds).
Cons: higher first cost than commodity plating; verify base metal quality.
Best for: faucets, shower trim, door levers across unit finishes.
Pricing: from mid-tier fixtures; PVD finish adder varies by brand, subject to change.
11) Terrazzo systems for lobbies and high-traffic corridors
When you model lifecycle cost, poured-in-place epoxy terrazzo often pencils out in high-traffic amenities versus carpet or VCT. The National Terrazzo & Mosaic Association outlines system families and applications in NTMA’s specification guides (2024–2025).
Pros: long service life, seamless cleanability, repairable; striking design potential.
Cons: higher upfront cost, specialized installers.
Best for: lobbies, elevator lobbies, mail rooms, club entries.
Pricing: from premium; lifecycle savings realized over years via reduced replacements, subject to change.
12) Cork and bamboo with FSC chain-of-custody (where applicable)
Renewable options can work in controlled conditions.
For bamboo and cork, ask for FSC chain-of-custody documentation where product claims are made, and pair with FloorScore/GREENGUARD adhesives and finishes.
Manage moisture carefully; specify tested acoustic underlayment assemblies for IIC/STC.
Pros: warm underfoot, bio-based story, solid acoustic absorption for wall applications.
Cons: moisture sensitivity and edge wear in hard-use areas; maintenance discipline required.
Best for: accent walls, low-moisture living areas in select buildings.
Pricing: from mid-range; factory-finished, higher-density products cost more, subject to change.
13) Antimicrobial claims: keep them compliant and honest
If you purchase “antimicrobial” surfaces, ensure claims don’t overreach. In the U.S., treated articles can only claim product protection; public-health protection claims require registration and efficacy data. Require vendors to align with EPA guidance on treated articles and antimicrobial testing.
Pros: protects the product surface itself in certain conditions.
Cons: can create compliance risk if marketed as protecting occupants; may add cost without operational benefit.
Best for: high-touch accessories where claims are limited and supported.
Pricing: varies widely; treat as a feature adder, subject to change.
14) Prefab shower panels and bathroom pods to compress schedules
A 2026 bright spot: factory-built wet areas. Solid-surface or laminated shower panels replace tile and cut install time; full bathroom pods can shift most trades off-site.
Industry and institute materials report significant schedule compression when pods are used, often installing in hours once delivered.
Pros: faster cycles, consistent QA, fewer trades stacking on site.
Cons: early design sop sets and crane/MEP coordination; repair strategies must be defined.
Best for: mid-rise and high-rise with repetitive unit types.
Pricing: from moderate for panels to higher for pods; savings realized in schedule and labor, subject to change.
15) Natural stone by application: set hardness and care expectations
Stone remains desirable, but right-sizing the species matters.
Softer stones like marble (calcite-dominant) scratch and etch more easily than harder options; granites and quartzites trend significantly harder due to quartz/feldspar content.
Use Mohs hardness as a directional guide and pair with care instructions and sealing schedules.
Pros: timeless look, unique slabs.
Cons: variable performance, maintenance burden in rentals if misapplied.
Best for: vanities and feature walls; use harder stones or engineered surfaces for kitchen worktops.
Pricing: from mid-high depending on quarry and finish; fabrication and thickness drive variance.

Sourcing and next steps
- Pilot before you roll: mock up one or two units with the 2026 spec package, then track punch, clean time, and resident feedback for 60–90 days.
- Write the maintenance plan into the spec: if a surface needs sealing, state the interval and who does it. No surprises for operations.
- Lock submittals early: ask for certificates and test reports with the first package so your team isn’t scrambling at turnover.
- For China-based procurement at scale, teams often engage a vetted aggregator to consolidate categories, confirm certifications, and manage logistics. One example is China-based sourcing support for apartment finishes. Disclosure: ChinaBestBuy is our product. Keep the relationship neutral and documentation-heavy—factory QC logs, pre-shipment inspections, and samples on every finish change.
