Painting a Triple-Decker in Boston: Costs, Permits, and What to Expect

Boston’s triple-deckers are part of the city’s DNA. Between 1880 and 1930, an estimated 15,000 triple-deckers were built across Dorchester, Roxbury, Jamaica Plain, Somerville, and South Boston. Today, these three-story wood-frame buildings still make up a significant portion of the housing stock in Greater Boston, and they need regular painting to stay protected and looking their best.

But painting a triple-decker in Boston is not the same as painting a single-family home. The height requires scaffolding. The age means lead paint is almost always present. And coordinating between three units adds complexity that most homeowners and landlords are not prepared for.

This guide covers what a triple-decker painting project actually costs in 2026, what permits and certifications are involved, and how to plan the job so it goes smoothly from start to finish.

How Much Does It Cost to Paint a Triple-Decker Exterior in Boston?

An exterior painting project on a triple-decker in Boston typically costs between $12,000 and $28,000 in 2026. That range is wide because several factors push costs higher compared to a standard two-story home.

Here is how the numbers break down:

Cost Factor	Typical Range
Paint and materials	$1,800 – $3,500
Scaffolding rental and setup	$2,000 – $5,000
Surface preparation (scraping, sanding, caulking, priming)	$3,000 – $6,000
Labor (painting, 2 coats minimum)	$5,000 – $10,000
Lead paint compliance (if pre-1978)	$1,000 – $3,500
Total exterior estimate	$12,000 – $28,000

For comparison, painting the exterior of a typical 1,800 sq ft single-family home in the Boston area runs between $4,500 and $9,000. Triple-deckers cost roughly 2x to 3x more because of the additional square footage (most triple-deckers have 3,500 to 5,500 sq ft of paintable exterior surface), the height requiring scaffolding on all sides, and the extensive prep work on aging wood siding.

Interior Painting Costs for a Full Triple-Decker

If you are painting all three units, expect to budget between $9,000 and $22,000 for a complete triple-decker interior painting project. That breaks down to roughly $3,000 to $7,500 per unit, depending on unit size, wall condition, and the number of rooms.

Most Boston triple-decker units have 5 to 7 rooms with 8 to 9 foot ceilings. Common cost drivers include:

• Wall repairs: Plaster walls in pre-war triple-deckers crack and chip over time. Patching and skim-coating add $500 to $1,500 per unit.
• Trim and millwork: Many triple-deckers have detailed window casings, baseboards, and door frames that take longer to prep and paint than modern flat trim.
• Tenant coordination: If tenants are in place, rooms need to be painted in a specific sequence so each area can be cleared and dried before the tenant returns.
• Lead paint: Interior surfaces in pre-1978 buildings are subject to the same EPA Renovation, Repair, and Painting (RRP) Rule as exteriors. Certified contractors must follow lead-safe work practices during any interior painting that disturbs more than 6 square feet of painted surface per room.

Landlords who are turning over a vacant unit can often save 10 to 15% on interior costs because the crew can work faster without furniture moving, scheduling restrictions, or tenant access coordination.

Why Scaffolding Changes Everything

This is the single biggest cost difference between painting a triple-decker and painting a regular house. A two-story home can usually be reached with extension ladders. A three-story building cannot.

Scaffolding rental for a full triple-decker exterior typically runs $2,000 to $5,000 for the duration of the project. That includes delivery, setup, breakdown, and removal. The total depends on how many sides of the building need scaffolding, whether the lot is tight (narrow Boston lots often mean scaffolding on all four sides), and the rental duration.

Most exterior triple-decker painting projects take 10 to 18 working days, depending on prep scope and weather. Scaffolding is rented by the week, so weather delays directly increase scaffolding costs. This is one reason why scheduling exterior work between May and October gives the best results and the lowest risk of delays in the Boston area.

Some contractors use boom lifts instead of scaffolding when lot conditions allow. Boom lifts can be faster to set up but require solid ground access and adequate clearance from overhead wires, which many triple-decker lots in Dorchester and South Boston do not have.

Lead Paint Rules for Triple-Deckers in Massachusetts

This is where many property owners run into trouble. Nearly every triple-decker in Boston was built before 1978, which means lead-based paint is almost certainly present on interior and exterior surfaces.

Federal law through EPA’s RRP Rule requires that any contractor working on pre-1978 housing must be an EPA-certified renovation firm and must assign a certified renovator to every project. In Massachusetts, the state has its own authorized lead program that enforces the same standards.

Here is what that means in practice for your triple-decker painting project:

• Your painting contractor must hold EPA RRP firm certification. Ask for proof before signing a contract.
• A certified renovator must be assigned to the project and present during all paint-disturbing activities.
• Work areas must be contained with polyethylene sheeting to prevent lead dust from spreading to occupied areas or the surrounding yard.
• Certain methods are prohibited, including open-flame burning of paint, power sanding without HEPA vacuum attachments, and dry scraping of large areas.
• After work is complete, the area must be cleaned and verified before containment is removed.

Lead compliance adds $1,000 to $3,500 to a typical triple-decker project, depending on the scope of paint disturbance. Skipping this requirement is not just a health risk. EPA enforcement actions have resulted in fines exceeding $37,500 per violation for contractors who ignore the rule.

Massachusetts also has its own lead paint law (M.G.L. c. 111, s. 197) that requires property owners to remove or manage lead hazards in homes where children under 6 reside. If you are a landlord renting units to families with young children, painting alone may not satisfy deleading requirements. A licensed lead inspector can test surfaces and advise whether full abatement, interim controls, or encapsulation with specialized coatings is needed.

Do You Need a Permit to Paint a Triple-Decker?

Standard painting work in Boston does not require a building permit. Painting is classified as routine maintenance under the Massachusetts State Building Code.

However, there are situations where permits or approvals may apply:

• Scaffolding on public sidewalks: If your scaffolding extends over a public sidewalk or into the street, you will need a permit from the City of Boston’s Public Works Department. Fees vary by location and duration.
• Historic districts: Properties in designated historic districts may need approval from the Boston Landmarks Commission before changing exterior colors. This applies to parts of the South End, Beacon Hill, Bay Village, and other protected areas.
• Structural repairs: If the painting project uncovers rotted siding, damaged soffits, or compromised structural elements that need replacement, a building permit may be required for the repair portion of the work.

Your painting contractor should be familiar with these local requirements. If you are unsure whether your property falls within a historic district, check the City of Boston’s Landmarks Commission website or call 311.

How to Plan a Triple-Decker Painting Project

“Every triple-decker project we take on in Boston starts with a thorough assessment of the building’s condition, especially the wood siding, trim, and porches,” says Vitalie Mahari, owner of Echo House Painting. “The prep work on a three-story wood-frame building often takes as long as the painting itself. Rushing that step is the fastest way to get a paint job that fails in two years instead of lasting seven to ten.”

Here is a practical timeline for planning your project:

2 to 3 Months Before

• Get estimates from 2 to 3 licensed exterior painting contractors who have experience with multi-story buildings.
• Verify EPA RRP certification for every contractor you are considering.
• If your property is in a historic district, submit color change requests early. Approval can take 4 to 6 weeks.

1 Month Before

• Notify tenants in writing about the project schedule, including expected noise, scaffolding placement, and any window access restrictions.
• Coordinate with your contractor on paint colors and finish types. Exterior wood siding in New England performs best with 100% acrylic latex paint in a satin or low-luster finish.
• Schedule any needed carpentry repairs (rotted clapboards, damaged window sills, porch railings) so they can be completed before or during painting.

During the Project

• Expect 10 to 18 working days for a full exterior. Interior work adds 3 to 5 days per unit.
• Weather delays are normal. Rain and temperatures below 50°F stop exterior painting. Build 3 to 5 buffer days into your schedule.
• Keep vehicles away from scaffolding areas and ensure the crew has clear access to all sides of the building.

Choosing the Right Paint for a Boston Triple-Decker

New England weather tests paint more aggressively than most regions in the US. Freeze-thaw cycles, salt air from the coast, summer humidity, and UV exposure all degrade exterior coatings. For a triple-decker exterior, invest in premium paint from Benjamin Moore or Sherwin-Williams rated for New England conditions.

Recommended products for triple-decker exteriors in the Boston area include 100% acrylic latex formulations with built-in mildewcide and UV stabilizers. These paints flex with temperature changes instead of cracking, which is critical on old wood siding that expands and contracts seasonally.

For interior painting, low-VOC and zero-VOC paints are strongly recommended, especially in occupied units. VOC levels matter more in triple-deckers than in detached homes because shared hallways and stairwells can carry paint fumes between floors.

Neighborhoods with the Most Triple-Deckers

If you own a triple-decker in any of these Boston neighborhoods, you are not alone. These are the areas where triple-decker painting projects are most common:

• Dorchester has the highest concentration in the city, with over 5,000 triple-deckers built during the early 1900s.
• South Boston and Roxbury were among the first neighborhoods where triple-deckers appeared in the 1880s.
• Jamaica Plain, particularly around Hyde Square and Jackson Square, features dense blocks of triple-deckers in various conditions.
• Somerville and Medford across the river have equally large concentrations.
• Suburban communities like Norwell, Needham, and Dedham have smaller numbers, but the same painting challenges apply to any three-story wood-frame building.

Frequently Asked Questions

How much does it cost to paint the exterior of a triple-decker in Boston?

Exterior painting for a triple-decker in Boston ranges from $12,000 to $28,000 in 2026. The final price depends on the building’s size, the condition of existing paint and siding, scaffolding requirements, and whether lead paint compliance is needed. Most projects fall in the $15,000 to $22,000 range for a building in average condition.

How long does it take to paint a triple-decker?

A full exterior painting project on a triple-decker typically takes 10 to 18 working days. Interior work adds 3 to 5 days per unit if all three units are being painted. Weather delays can extend the timeline, so building in a 1 to 2 week buffer during spring or fall is recommended.

Do I need a permit to paint a triple-decker in Boston?

No building permit is needed for standard painting work. However, if scaffolding extends over a public sidewalk, you will need a permit from Boston Public Works. Properties in historic districts may also need approval from the Boston Landmarks Commission before changing exterior colors.

Is lead paint always present in Boston triple-deckers?

Almost always, yes. The vast majority of Boston’s triple-deckers were built between 1880 and 1930, well before lead paint was banned in 1978. Any contractor you hire must be EPA RRP-certified and must follow lead-safe work practices when disturbing painted surfaces.

Can I paint a triple-decker myself to save money?

DIY exterior painting on a three-story building is strongly discouraged. Working at heights above 25 feet requires proper scaffolding and fall protection. Additionally, if the building was constructed before 1978, the EPA’s RRP Rule applies to any paid renovation work, and Massachusetts lead paint laws create liability for property owners even when doing the work themselves. Hiring a licensed and insured painting contractor protects both your safety and your legal standing.

What is the best time of year to paint a triple-decker exterior in Boston?

May through October offers the most reliable painting weather in Greater Boston. Temperatures need to stay above 50°F for most exterior paints to cure properly, and low humidity helps with adhesion and drying. Scheduling in late spring or early fall avoids the peak summer heat and the rush of the busiest months (June and July), which can mean better availability and pricing from contractors.

How often should a triple-decker exterior be repainted?

With proper surface preparation and premium paint, a triple-decker exterior in Boston should last 7 to 10 years before repainting. South-facing and west-facing walls may need attention sooner due to higher UV and wind exposure. Regular inspections every 2 to 3 years can catch peeling or chalking early, before it becomes a full repaint situation.
