How Much Does It Cost to Paint a 1500 Sq Ft House Interior in 2026?
The cost to paint 1500 sq ft house interior typically runs $3,000 to $7,500 in 2026 for a professional job, with most homeowners landing around $4,000–$5,500 for walls plus trim. A walls-only refresh in a home with good existing paint can come in near $3,000–$4,500, while a full-scope job — walls, ceilings, trim, and doors — usually runs $5,500–$9,000. DIY painters spend far less on cash ($600–$1,500 in materials) but invest 40–80 hours of their own time, roughly a long weekend per two rooms for a careful job.
Quick-answer table (typical 2026 professional costs, 1500 sq ft home):

Cost to Paint 1500 Sq Ft House Interior by Scope
Painters price by scope more than by raw floor area. A 1500 sq ft ranch with 8-foot ceilings and minimal trim is a fundamentally different job than a 1500 sq ft colonial with crown molding, wainscoting, and a two-story foyer. Here’s how scope changes the price:
| Scope | What’s included | Typical cost |
|---|---|---|
| Walls only | Two coats on walls, basic masking | $3,000–$4,500 |
| + Trim & baseboards | Walls plus all trim, doors, and baseboards | $4,500–$6,500 |
| + Ceilings | Everything above, plus ceilings in all rooms | $6,000–$9,000 |
| + Closets & pantry | Interior closet walls, shelving edges | Add $300–$800 |
| Accent walls (each) | Bold color or specialty finish, one wall | Add $150–$400 |
| Full exterior too | Siding, trim, shutters | Separate $3,000–$8,000+ job |
Painting the outside as well? See our guide to exterior house painting cost for 2026 pricing by home size and siding type.
Trim is the great multiplier: painting baseboards, casings, and doors adds 30–40% to a walls-only quote because it demands slow brush work, precise taping, and often a different (more expensive) enamel paint.
Room-by-Room Cost Breakdown
Not every room costs the same. A small powder room takes a painter an hour or two; a vaulted living room can eat a full day. Typical 2026 per-room professional costs:
| Room (typical size) | Typical cost | Notes |
|---|---|---|
| Bedroom (10×12, walls + trim) | $400–$900 | Standard 8-ft ceilings, two coats |
| Living room (16×20) | $700–$1,800 | Larger wall area; vaulted ceilings push higher |
| Kitchen | $450–$1,100 | Less wall space (cabinets), but fiddly cutting-in |
| Bathroom | $250–$650 | Small, but moisture-rated paint costs more |
| Hallway | $300–$750 | Linear footage adds up fast |
| Dining room | $500–$1,100 | Often includes wainscoting or chair rail |
| Foyer / stairwell | $500–$1,500 | Two-story entries need scaffolding |
| Whole home (1500 sq ft) | $3,000–$7,500 | Walls + trim, standard scope |
A whole-home discount of 10–20% is common when you book three or more rooms with one crew — always ask, since painters prefer one mobilization to three.
Paint and Materials: How Many Gallons and What They Cost
For a 1500 sq ft home, plan on roughly 1,500–2,000 sq ft of paintable wall area (walls run about 3–4× floor area minus doors and windows, with ceilings adding another 1,500). At ~350 sq ft per gallon per coat:
| Material | Typical 2026 cost | Needed for 1500 sq ft |
|---|---|---|
| Budget interior paint | $15–$25/gal | 8–12 gallons for two coats |
| Mid-grade paint (most popular) | $30–$50/gal | 8–12 gallons for two coats |
| Premium paint (one-coat coverage claims) | $55–$80/gal | 6–10 gallons |
| Primer | $10–$25/gal | 3–5 gallons for bare/dark walls |
| Supplies (tape, rollers, drop cloths, caulk) | $80–$200 | One-time, reusable |
| Materials total (pro job) | $400–$1,200 | Usually 20–30% of the bid |
Paint quality matters more than brand loyalty: mid-grade paints cover in two true coats, while bargain paint often needs three — wiping out the per-gallon savings in extra labor. Low-VOC and zero-VOC lines now cost about the same as conventional paints; the EPA’s Safer Choice program lists certified low-emission options if indoor air quality matters to your household.
7 Cost Drivers That Raise Interior Painting Costs
Surface prep. Patching nail holes, sanding, caulking gaps, and priming stains is where cheap bids cut corners. Expect $200–$600 in prep on a 1500 sq ft home — and double that if there’s old wallpaper to strip.
Ceiling height. Anything over 9 feet slows the crew and may need extension poles or scaffolding; vaulted great rooms can add $500–$1,500 alone.
Trim quantity. Crown molding, wainscoting, and multi-piece casings are beautiful and expensive to paint — budget $1–$3 per linear foot of trim.
Color change. Going from dark to light (or to a bold accent) typically needs a primer coat plus two finish coats — roughly 25–40% more labor than a same-color refresh.
Wall condition. Textured walls drink 30–40% more paint than smooth drywall; damaged plaster or failing paint needs skim-coating first.
Lead paint. Homes built before 1978 may contain lead paint, and federal rules require lead-safe work practices by certified renovators — add $500–$2,000 for compliant prep and containment.
Region. Metro labor rates run 15–30% above the national average; rural and Southern markets often come in below it.
Cost to Paint 1500 Sq Ft House Interior: DIY vs Hiring a Pro
| Factor | DIY | Hired pro |
|---|---|---|
| Cash outlay | $600–$1,500 (materials + tools) | $3,000–$7,500 |
| Your time | 40–80 hours over 2–4 weekends | Zero — crew of 2–3 finishes in 2–4 days |
| Finish quality | Good with patience; cut lines are the hard part | Crisp lines, even coverage, sprayed trim options |
| Prep thoroughness | Usually underestimated (the #1 DIY regret) | Included in bid — sanding, caulk, primer |
| Equipment | Buy or rent ladders, poles, sprayer ($100–$300) | Included |
| Warranty | None — touch-ups are on you | Typically 1–2 years on workmanship |
| Best for | 1–2 rooms, same-color refresh, tight budget | Whole home, color changes, high ceilings, selling soon |
The hybrid sweet spot: DIY the easy rooms, hire pros for the hard ones. Bedrooms with 8-foot ceilings are forgiving; two-story foyers, stairwells, and heavy trim work are where pros earn their fee. For the full breakdown, our house painting cost calculator lets you toggle DIY vs pro pricing.
7 Ways to Save on Interior Painting Costs
Keep the same color family. A same-tone refresh often needs just two coats with no primer — the cheapest pro scenario.
Do your own prep. Moving furniture, removing outlet covers, and laying drop cloths saves $200–$400 in billable hours.
Limit the palette. One wall color throughout (plus one trim color) cuts material waste and speeds the crew — every extra color adds setup time.
Skip the ceilings (if they’re fine). Ceilings add 30–40% to the job; if they’re clean and white, leave them.
Book the off-season. Late fall and winter are slow months for painters — 10–15% discounts are common when crews want to stay busy.
Buy paint during sales. Major retailers run 30–40% off paint events several times a year; ask your painter if you can supply it (some allow, some insist on their own).
Get 3–4 written bids. Whole-home interior quotes for identical scope routinely vary 20–30% between painters — the spread on a $5,000 job is real money.

For a detailed breakdown of interior house painting cost per square foot — including how rates shift with ceilings, trim, and region — see our 2026 guide.

Roughly 8–12 gallons for two coats on walls, plus 3–5 gallons of primer if you’re covering dark colors or bare drywall. Ceilings add another 4–6 gallons. Buy 10% extra — running out mid-wall causes visible color bands.
How long does it take to paint a 1500 sq ft house interior?
A professional crew of 2–3 painters typically needs 2–4 days for walls and trim. DIY takes 2–3× longer — plan on 2–4 weekends for a careful whole-home job.
Is it cheaper to paint yourself or hire a painter?
DIY costs $600–$1,500 in materials versus $3,000–$7,500 for a pro — a savings of $2,500–$6,000. But DIY costs 40–80 hours of your time, and pros deliver better cut lines, faster completion, and a workmanship warranty.
The Bottom Line
The cost to paint 1500 sq ft house interior lands at $3,000–$7,500 for most professional jobs in 2026 — roughly $2–$5 per square foot depending on whether ceilings, trim, and repairs are in scope. Keep the color family, do your own furniture-moving, and book in the off-season to land near the bottom of the range. DIY the bedrooms if your budget is tight, but hire pros for stairwells, vaulted ceilings, and anything involving pre-1978 paint.
Cost ranges are 2026 national typicals based on painter pricing data and remodeling cost surveys; actual quotes vary by region, home condition, and scope. Always get multiple written estimates before committing.
