What is the cost of painting a 400 square foot laneway house in Vancouver inside and out?

Painting a 400 sq ft laneway house in Vancouver — interior and exterior combined — will typically cost $4,000–$9,000, depending on surface condition, prep requirements, and finish quality.

The wide range reflects real variables: a well-maintained laneway with smooth drywall, clean siding, and minimal trim detail sits at the lower end, while one with peeling exterior paint, mould on north-facing walls, cedar siding needing tannin-blocking primer, or extensive caulking work pushes toward the top.

Interior Painting

A 400 sq ft laneway house typically has a compact open-plan main area, a small bathroom, and sometimes a sleeping loft. Expect roughly 600–900 sq ft of paintable wall and ceiling surface once you account for doors, windows, and kitchen cabinetry. At Metro Vancouver rates of $2.50–$5.00 per sq ft for walls, interior painting on a laneway usually runs $1,800–$3,500 all-in, including ceiling, trim, and a bathroom with moisture-resistant paint.

Lofts add cost — if the sleeping area has a sloped ceiling or requires ladder work above 10 feet, expect a 30–40% premium on that portion of the job. Bathroom walls should be painted with a dedicated kitchen and bath formula like Benjamin Moore Aura Bath & Spa or Sherwin-Williams Emerald ($60–$90/gallon) to handle the humidity that builds up in a small, often poorly ventilated space.

Exterior Painting

A 400 sq ft footprint laneway house has roughly 600–900 sq ft of exterior wall surface depending on ceiling height and whether it's one or two storeys. At Metro Vancouver exterior rates of $3.50–$7.00 per sq ft, exterior painting runs $2,500–$6,000, including pressure washing, caulking, spot priming, and two coats of a quality 100% acrylic exterior latex like Benjamin Moore Aura Exterior or Sherwin-Williams Duration.

The exterior cost is heavily influenced by siding type. Hardie board (fibre cement) — common on newer Vancouver laneways — needs a cementitious-compatible primer and acrylic topcoat, but is relatively straightforward to spray. Cedar siding or shingles require a tannin-blocking primer before topcoating — skipping this causes brown bleed-through staining within weeks, especially in Metro Vancouver's wet climate. Stucco needs crack repair with elastomeric filler before painting, and elastomeric coatings ($70–$120/gallon) are worth the investment on older stucco to bridge hairline cracks before they let water in.

Key Cost Factors for Laneway Houses Specifically

Mould and mildew prep is often the biggest wildcard. Laneways are frequently shaded by the main house and surrounding fencing, creating exactly the low-airflow, damp conditions where mould thrives on Vancouver's North Shore and East Side. Any green or black growth on exterior surfaces must be treated with a mould-killing wash before repainting — not just pressure washed. Budget an extra $300–$600 if mould remediation is needed.

Access and scaffolding on a two-storey laneway adds cost. Laneways are often tight against fences or the main house, making ladder placement tricky. A contractor may need scaffolding on one or more sides, adding $500–$1,000 to the job.

Paint quality matters more than it seems on a small building. A laneway house exterior gets the same UV and rain exposure as a full-sized home. Spending $80–$110/gallon on premium paint versus $45/gallon on contractor-grade costs maybe $200–$300 more in materials on a building this size — but the difference between a 5-year and a 12-year finish is entirely in the paint quality and prep.

Practical Tips

Book exterior work for June through August — Metro Vancouver's reliable dry window. Reputable painters fill their summer schedules by March, so plan ahead. Interior work can proceed year-round with proper ventilation.

Get at least two quotes and ask each contractor to itemize prep, primer, and number of coats separately — this tells you a lot about how thorough their approach is.
