Painting and wall finishes often represent 5–15% of a tenant improvement budget—a surprisingly significant line item that tenants and landlords frequently underestimate. Getting this cost right means the difference between a professional, turnkey space and a project that bleeds money into unexpected touch-ups. This guide breaks down what you'll actually pay for painting and finishes in a typical tenant build-out.
Labor Costs Dominate the Line Item
Painting labor typically runs $2–$6 per square foot for standard drywall finish work, depending on your market, wall condition, and complexity. A 5,000-square-foot retail or office space will cost between $10,000 and $30,000 in labor alone. Skilled painters move faster in new construction (where walls are clean and primed), but older buildings or spaces requiring surface repair can double labor time. Most contractors estimate 1,500–2,000 square feet per painter per day for standard two-coat applications.
If your build-out includes accent walls, textured finishes, or specialty paint (antimicrobial for healthcare, high-durability for high-traffic retail), expect an additional $1–$3 per square foot on top of the base labor rate.
Material Costs: Premium Paint Adds Up
Interior paint itself ranges from $25–$60 per gallon for builder-grade latex, but commercial-grade paints run $50–$100 per gallon. You'll need approximately one gallon per 300–400 square feet for two coats. A 5,000-square-foot space typically requires 12–17 gallons of finish paint, plus primer.
Specialty finishes command premiums:
- Low-VOC or zero-VOC paints: $60–$120 per gallon (often required by lease riders or municipal code)
- Epoxy or polyurethane coatings (for warehouse or industrial spaces): $80–$150 per gallon
- Antimicrobial or hospital-grade finishes: $90–$140 per gallon
- Textured or acoustic finishes: $40–$90 per gallon plus application charges
Primer, drywall patching compound, sealers, and protection materials typically add 10–15% to material costs.
Wall Preparation: The Hidden Budget Killer
Surface preparation often exceeds painting cost itself in older buildings. Budget separately for:
- Drywall patching and mudding: $1–$3 per square foot (depends on wall condition)
- Sanding and filling: $0.50–$1.50 per square foot
- Primer application: $0.75–$1.50 per square foot
A 5,000-square-foot space with existing, damaged walls might require $5,000–$10,000 in prep work before the first coat of finish paint touches the wall. Always request a site walk with your contractor to assess drywall condition—surprises here are expensive.
Timeline Expectations
Standard painting for a tenant build-out takes 1–3 weeks depending on scope. Factor in:
- Prep work: 3–7 days (varies by condition)
- Primer application: 2–4 days
- Finish coats: 3–5 days (drying time between coats adds 24 hours minimum)
- Touch-ups and final inspection: 1–2 days
Humid environments or cold weather can extend drying times significantly. Schedule painting near the end of your construction timeline but before flooring and final fixtures go in—this prevents scuffs and damage.
Budgeting by Space Type
Office and retail spaces differ in finish requirements. Retail often demands higher-durability finishes and more frequent color changes ($3–$6 per square foot for materials and labor). Medical or food-service spaces require low-VOC and antimicrobial finishes, pushing costs to $4–$8 per square foot. Standard office interiors with neutral colors cost $2–$4 per square foot.
Common Cost-Saving Moves
Standardize color palettes—fewer colors mean faster application and less paint waste. Opt for eggshell or satin finishes over matte (easier to clean and maintain, minimal aesthetic trade-off). If budget is tight, use builder-grade paint on back-of-house or storage areas and reserve premium products for client-facing spaces. Negotiate painter rates as part of a larger general contractor agreement rather than hiring paint-only subcontractors.
Working With Contractors
When getting bids, require painters to specify paint grade, coverage per gallon, and prep scope in writing. Request references from recent tenant improvement projects (not just single-family residential work—TI painting is different). Use Mercoly to compare and find trusted tenant improvement providers who can bundle painting with other construction services, often reducing overall project friction and cost.
Frequently Asked Questions
Q: Should I use the landlord's painter or hire my own during a tenant improvement? A: Review your lease carefully—most require using the landlord's approved contractor list, but you can negotiate pricing and scope. If you have flexibility, hiring independently often provides better cost control and timeline accountability.
Q: How much should I budget for paint touch-ups after move-in? A: Plan 2–5% of total painting cost for post-occupancy touch-ups and minor repairs over the first year; high-traffic areas wear faster.
Q: Can I use leftover paint from the builder's original construction? A: Only if you have documentation of the exact product, batch, and finish code—color matching after months of storage is nearly impossible, and mixing batches creates visible variations.
