Wood Framing 101: What Every Developer Should Know

If you're developing multifamily housing in Texas, wood framing is almost certainly part of your project. It's the most cost-effective structural system for garden-style apartments, wrap developments, and podium buildings — and it's the backbone of the state's booming multifamily market. But a lot of developers, especially those newer to ground-up construction, don't have a deep understanding of what wood framing actually involves. That gap can lead to unrealistic schedules, budget surprises, and friction with your framing contractor. Here's a practical overview of what you need to know. What Is Type V Wood-Frame Construction? Most multifamily wood-frame buildings fall under **Type V construction** as defined by the International Building Code (IBC). Type V allows combustible materials — primarily dimensional lumber — for structural framing. Within Type V, there are two subcategories: - Type V-A (protected): Requires fire-resistive construction, typically achieved through fire-rated assemblies (drywall, fire-blocking, etc.). Allows taller buildings. - Type V-B (unprotected): No fire-resistance rating required for structural elements. Generally limited to lower building heights and smaller footprints. The type your project falls under affects everything from framing specifications to inspection requirements. Your architect and structural engineer will determine this early in design — but as a developer, you should understand which category you're in and what it means for your framing scope. The Basic Components of a Wood Frame A wood-framed building is made up of several interconnected systems: Foundation and sill plate: The framing starts at the foundation. Pressure-treated sill plates are anchored to the concrete, creating the base for the wall framing above. Wall framing: Vertical studs (typically 2×6 for exterior walls, 2×4 for interior) are assembled into wall panels. Headers span openings for doors and windows. Double top plates tie the walls together and carry loads to the studs below. Floor systems: Between stories, engineered floor joists or I-joists span between bearing walls and beams. Subfloor sheathing is nailed and glued on top, creating the platform for the next level of framing. Roof framing: Roof trusses (pre-engineered and delivered to site) or conventionally framed rafters form the roof structure. Sheathing is applied before roofing. Shear walls: These are critical for lateral resistance — they keep the building from racking under wind or seismic loads. Shear walls are specified by the structural engineer and require specific nailing patterns, hold-downs, and sheathing. How Framing Is Sequenced On a multifamily project, framing typically follows this sequence: 1. Slab or podium deck is complete — framing can't start until the surface below is ready 2. First-floor wall framing — exterior and interior walls are framed and stood up 3. First-floor shear walls and sheathing — structural panels are applied and nailed per engineering 4. Floor system installation — joists, blocking, and subfloor for the level above 5. Repeat for each story 6. Roof truss installation and sheathing 7. Windows and exterior doors — rough openings are framed during wall framing; units are installed after sheathing 8. Rough framing inspection — before insulation and drywall can proceed the pace of this sequence depends heavily on crew size, material availability, and weather. A well-run framing contractor will have a detailed look-ahead schedule that ties framing milestones to your overall project schedule. Materials: Lumber and Engineered Wood Modern wood framing uses a mix of dimensional lumber and engineered wood products: Dimensional lumber (2×4, 2×6, 2×10, etc.) is used for studs, plates, headers, and blocking. Lumber quality and moisture content matter — wet or warped lumber leads to callbacks and quality issues down the line. Engineered lumber — LVL (laminated veneer lumber), PSL (parallel strand lumber), and LSL (laminated strand lumber) — is used for beams, headers, and ridge members where higher strength or longer spans are required. I-joists are the standard for floor systems in multifamily construction. They're dimensionally stable, lightweight, and allow mechanical runs through the web. Roof trusses are almost always pre-engineered and fabricated off-site. Lead times matter — trusses need to be ordered early in the project, often before framing begins. Lumber pricing is volatile. If your project is in preconstruction, work with your framing contractor to understand current market conditions and whether it makes sense to lock in pricing early. What Fire-Blocking and Draft-Stopping Mean for Your Schedule Fire-blocking and draft-stopping are code requirements that slow down framing — and they're often underestimated in project schedules. Fire-blocking fills concealed spaces in wall cavities at specific intervals to slow the spread of fire. It's required at floor lines, at the top and bottom of stairs, and in other locations specified by code. Draft-stopping divides large, concealed spaces (like attic areas) into smaller compartments to limit smoke and fire spread. Both require additional material and labor, and both are inspected. If your framing contractor isn't accounting for these in their bid and schedule, you'll find out at inspection — which is the wrong time. The Framing Contractor's Role Beyond Framing On a well-run project, your framing contractor is more than a crew with nail guns. They should be: - Flagging drawing issues before they become field problems - Coordinating with MEP trades on rough-in locations and penetrations - Managing material deliveries to keep the site organized and the crew productive - Communicating proactively with your project manager on schedule and scope the framing phase sets the pace for every trade that follows. A framing contractor who runs a tight operation — clean site, accurate work, proactive communication — makes everyone else's job easier. What to Expect on a Typical Multifamily Framing Timeline Framing duration varies significantly based on building size, story count, and crew size. As a rough benchmark: - Garden-style 3-story, 100 units: 10–16 weeks of framing - Wrap or podium, 200+ units: 20–30+ weeks depending on phasing - Single building, 4-story, 50 units: 8–12 weeks These are rough ranges. Your framing contractor should provide a detailed schedule based on your specific drawings and site conditions — not a ballpark number. The Bottom Line Wood framing is a mature, proven system — but it's not simple. The difference between a framing contractor who understands the full scope of their work and one who just puts up walls shows up in your schedule, your inspection results, and your relationship with every trade that follows. If you're planning a multifamily project in Texas and want to talk through the framing scope, we're happy to have that conversation early — before the drawings are finalized and before the schedule is set in stone. That's where we add the most value.
