Multi-Family Renovation Cost: What Commercial Developers Should Budget

Multi-family value-add underwriting lives or dies on renovation cost accuracy. Set the budget too high and you underbid; set it too low and you overbid and eat the overage during construction. The gap between a realistic renovation budget and an aspirational one is typically 15-30% — and that's the gap between a deal that works and a deal that doesn't.

This post walks through multi-family renovation cost by scope category — unit turns, common areas, exterior envelope, and roofing — with realistic 2026 benchmarks. Where numbers vary significantly by market and condition, we flag the drivers. Where they're relatively stable, we give the range.

Treat these numbers as starting points for underwriting, not contract-quality pricing. Actual contracts reflect specific property conditions, market labor rates, material costs at time of bid, and scope-specific decisions we can't know from a blog post.

Unit Turn Costs

Unit turns are the largest single category in most multi-family renovations. Per-unit costs vary dramatically based on starting condition (cosmetic turn vs. full renovation), scope depth (paint/carpet only, or full kitchen/bath replacement), building vintage (1970s-1980s properties surface more surprise scope than newer inventory), and market labor rates.

Cosmetic unit turn (paint, carpet, minor repair): $3,000–$8,000 per unit. Basic refresh with existing kitchen and bath. Appropriate for recent construction with intact finishes.

Light renovation (paint, flooring upgrade, appliance replacement): $8,000–$18,000 per unit. Replaces wearing items, upgrades appliances, refreshes visual finishes. Common for 2000s-vintage properties at first renovation cycle.

Moderate renovation (above plus cabinet resurfacing, countertops, fixtures): $18,000–$35,000 per unit. Meaningfully upgrades perceived quality. Common for 1980s-1990s garden properties repositioning for rent growth.

Heavy renovation (above plus cabinet replacement, flooring replacement, fixture upgrade, appliance package): $35,000–$60,000+ per unit. Near-complete interior upgrade. Appropriate for major repositioning or class upgrade scenarios.

Gut renovation (full demolition and rebuild of interior): $75,000–$150,000+ per unit. Appropriate for distressed assets or major repositioning of very-old inventory. Cost begins to approach new-construction territory.

Numbers assume crew access, sequential turn flow (not simultaneous 100% turns), and standard finish quality. Super-high-end finishes, tight schedules, or difficult access all push costs higher.

Common Area Costs

Common area renovation — leasing office, fitness center, pool area, clubhouse — is usually budgeted as a single lump-sum scope rather than per-unit.

• Leasing office refresh: $50,000–$150,000 (paint, finishes, furniture, minor reconfiguration)
• Leasing office full renovation: $150,000–$500,000 (significant layout changes, millwork, upgraded finishes)
• Fitness center upgrade: $75,000–$250,000 (equipment replacement, flooring, mirrors, HVAC)
• Pool and deck renovation: $100,000–$400,000 (surfacing, deck replacement, code compliance, furniture)
• Clubhouse / amenity full renovation: $200,000–$1,000,000+

Common area spend is where value-add operators differentiate their properties from competitors. Don't under-scope this category if the investment thesis depends on perceived asset class upgrade.

Exterior Envelope Costs

Exterior envelope work — siding, paint, windows, weather barrier — varies by property size and envelope condition.

• Exterior paint only: $0.50–$1.50 per square foot of wall area
• Exterior paint plus minor repair: $1.00–$3.00 per square foot
• Siding replacement: $5–$15 per square foot (depends on hardie, vinyl, stucco, substrate)
• Window replacement: $500–$1,500 per unit window
• Weather barrier and envelope rework: $3–$10 per square foot

Roofing Costs

Roofing is often the single largest exterior scope item and can make or break a renovation budget.

• Commercial flat roof replacement (TPO/EPDM): $7–$15 per square foot installed
• Commercial flat roof recover (over existing): $4–$9 per square foot
• Shingle roof replacement: $4.50–$9 per square foot
• Metal roofing: $10–$25 per square foot

Self-perform roofing typically comes in 10-25% below subcontracted pricing for the same scope because there's no GC markup on sub labor and material.

Mechanical, Electrical, and Plumbing (MEP)

MEP scope varies enormously based on property vintage and what systems need updating.

• Electrical panel upgrades: $1,500–$5,000 per unit panel
• Whole-property service upgrade: $50,000–$500,000
• HVAC replacement: $3,000–$8,000 per unit (split-system replacement)
• Plumbing repipe (whole property): $500,000–$3,000,000+

Contingency and Soft Costs

Beyond direct construction costs, budget for:

• Construction contingency: 5-15% of direct cost depending on property vintage and scope uncertainty
• Architect/engineer fees: 3-8% of construction cost
• Permits and inspections: 1-3% of construction cost
• Owner soft costs: 1-3% of construction cost
• FF&E: varies by scope; separate budget line
• Lost rent during turns: 2-8 weeks per unit depending on scope depth

Underwriting that omits these categories looks cheaper than it is. Real projects have these costs.

What Moves the Number

Beyond scope, these factors shift per-unit renovation cost materially:

• Market labor rates — Houston/Texas metros cheaper than coastal markets; Louisiana sometimes cheaper than Texas
• Building vintage — 1970s-1980s properties surface more unexpected condition than newer inventory
• Property class — Class A/B+ renovation at higher finish standards costs more per unit
• Occupied vs. vacant — occupied renovation adds coordination cost; full-vacancy allows faster crews
• Access — garden-style properties cheaper than multi-story without elevators
• Weather exposure — hurricane markets require envelope-grade work everywhere
• Hidden conditions — aging mechanicals, electrical, or structural issues surface surprise costs

What We Do at Pillars of Seven

We've delivered multi-family renovations across Louisiana and Texas totaling thousands of units and millions of square feet. Our in-house roofing crew handles envelope-critical roofing scope directly, which removes the largest exterior cost variance from our project budgets.

Our preconstruction services develop budgets at the level of detail required to underwrite a deal confidently. If you're underwriting a multi-family acquisition or value-add project and want a reality-check on the renovation numbers, let's talk.
