How much does siding cost on a Philadelphia rowhouse?

It depends on how many walls are sided. HomeAdvisor reports about $10,854 on average for vinyl projects in Philadelphia, with typical projects between about $4,000 and $16,000. Rear-wall-only jobs are often smaller in total but cost more per square foot because of tight access.

Do I need a permit for siding in Philadelphia?

Yes. L&I’s EZ Exterior Walls permit covers new wall coverings on townhouses up to three stories without plans. Historic properties need Historical Commission approval first.

Is fiber cement worth it on a Philadelphia home?

It costs more than vinyl but is non-combustible, impact-resistant and suits older homes. In the Middle Atlantic region it recouped about 99% of its cost at resale in the 2025 Cost vs. Value Report.

What if my house has asbestos shingles?

Mention them when you call. Philadelphia has its own additional rules for renovation work involving asbestos, so the contractor may recommend testing and a certified crew.

Rowhouses and twins are a different kind of job

Roughly four in ten Philadelphia homes were built before 1940, and most are brick rowhouses and twins. That changes what “new siding” means:

Smaller areas. Siding is usually on the rear wall, the side wall of an end unit or twin, a bay, a dormer, a third-floor addition or a porch enclosure – often a few hundred square feet rather than a whole house.
Harder access. Rear walls face narrow yards and alleys. Materials are carried in by hand, scaffolding has to fit tight spaces, and the neighbor’s property has to be protected.
Roof-to-wall joints. Rear additions and shed roofs meet the main wall at joints where leaks often start. Good flashing there matters more than the siding itself.
Old layers and old materials. Aluminum over old wood, asbestos-cement shingles and lead paint are common. Removal and lead-safe work add time and cost.

So a Philadelphia rowhouse job can be small in total but relatively expensive per square foot. Frame single homes in Northeast and Northwest Philadelphia are priced more like suburban jobs.

What adds to the price

Tear-off and disposal of old siding, typically $1,000 to $3,000 nationally on an average home; less on a small rear wall, more with several layers.
Asbestos-cement shingles. Philadelphia has its own additional rules for renovating buildings that contain asbestos, beyond state and federal rules; plan for testing and proper handling.
Lead paint. On pre-1978 homes, disturbing more than 20 square feet of painted exterior requires an EPA-certified firm using lead-safe practices.
Sheathing and framing repairs, typically $500 to $5,000 nationally depending on what turns up.
Trim, soffit and fascia, especially at rear additions and bays.
Permit fees for the city’s EZ Exterior Walls permit.

Philadelphia’s permit: the EZ Exterior Walls permit

Pennsylvania’s Uniform Construction Code generally excludes installing vinyl or aluminum siding on existing homes, but the City of Philadelphia runs its own permit process. Its Department of Licenses and Inspections offers an EZ Exterior Walls permit for new exterior wall coverings on townhouses up to three stories, issued without plans when the work meets the permit’s conditions and design limits. Covered materials include vinyl, fiber cement, wood siding, shakes and shingles and stucco. Historic properties need Philadelphia Historical Commission approval first, and facade changes in certain designated areas need City Planning Commission approval. Ask the contractor to pull the permit in their name before work starts.

Vinyl or fiber cement in Philadelphia?

Vinyl is the most common choice for rear walls and additions: it is the least expensive, never needs paint and is easy to handle in tight spaces. Fiber cement costs more and weighs more, but it is non-combustible, resists impacts and gives a painted-wood look that suits older homes and historic blocks. On homes where fire separation between closely spaced buildings is a concern, ask the contractor what the code requires for your wall.

Small repairs versus full re-siding

If only a few panels are cracked or missing, a repair is far cheaper: HomeAdvisor reports vinyl siding repairs in nearby Norristown averaging about $769. The catch is matching – older panels fade and many profiles are discontinued, so a patch may stand out.

Resale value

In the 2025 Cost vs. Value Report for the Middle Atlantic region, vinyl siding replacement recouped about 96% of its cost at resale and fiber cement about 99%. On rowhouses, rear-wall siding is less visible to buyers than a front facade, but inspectors and appraisers do note failing cladding, water damage and old asbestos or lead – so a well-documented re-siding job still helps a sale.

Hiring rules in Pennsylvania

Contractors who do $5,000 or more of home improvement work a year must register with the Pennsylvania Attorney General, and the registration number has to appear on contracts and advertising. Home improvement contracts of $500 or more must be in writing, and you have three business days to cancel. Look up the registration before you sign.

A worked example for a twin

Consider a Philadelphia twin with siding on the exposed side wall and the rear, about 900 square feet in total. Using national installed ranges of roughly $3 to $12 per square foot for vinyl and $5 to $14 for fiber cement, the siding alone would come to about $2,700 to $10,800 in vinyl or $4,500 to $12,600 in fiber cement. Add tear-off, trim, flashing at the roof lines and the permit, and a realistic total lands in the range of the HomeAdvisor Philadelphia average – or higher if asbestos, lead or rotted framing turn up. A rear-wall-only rowhouse job can be well below that; a frame single in the Northeast can be above it.

When to schedule

Philadelphia contractors are busiest in spring. Late summer and fall are often easier to schedule, and fall weather is usually good for installation. Vinyl can be installed in the cold with extra clearance, but tight rowhouse jobs are easier in mild weather, and paint and sealants have minimum temperatures.

How to get comparable quotes

Ask each contractor how they will access the rear and protect neighboring property
Ask about asbestos and lead, and how they are priced and handled
Make sure flashing at roof-to-wall joints and around windows is in the scope
Confirm who pulls the EZ permit and whether historic or planning approval applies
