Rear addition on a Trafford house, built by AllTrades Contracting Group
Borough of Trafford · 15085

Additions & ADUsin Trafford, PA

Westinghouse planned Trafford as a factory town on a hillside in 1902, and houses of five rooms are still the norm. When yours runs short, our carpenters come over from the shop on Forest Avenue, check the lot and the sewer line, and build onto the house with the same care it was built with.

Trafford Additions

Five-room houses,and families that need six.

Some 42% of Trafford's houses top out at two bedrooms, and half its owners moved in from 2010 on. An addition here is usually one well-built room, not a wing.

  1. Bedroom three, out the back

    About 42% of the borough's homes stop at two bedrooms. With kids in 32% of households, a couple who began with one bedroom and a nursery soon wonders where a third could fit.

    How we build it

    A single-story bedroom off the rear wall, or one framed above a new back room, with floor heights matched to the old house. A closet goes into the plan, and a duct from the furnace keeps it as warm as the rooms upstairs.

    Room additions
  2. Space for the kitchen table

    In houses this size the kitchen may seat only two. Families who cook at home want several more feet of floor, enough for a table, a pantry cabinet or two people working side by side.

    How we build it

    A bump-out on new footings, the old back wall replaced by a beam, the floor carried through level. If the job's value crosses the borough's threshold, the borough tests the sewer lateral before issuing the permit, and we line that up.

    Bump-outs
  3. A half bath by the back door

    Some older Trafford houses have a single bathroom, upstairs. Their owners want a powder room plus hooks for coats and boots at the back door, so nobody tracks through the house to wash up.

    How we build it

    A compact rear room holding a toilet, lavatory and bench, set on footings below frost. Those two fixtures, on a job above $10,000, bring the lateral test into play, so Public Works gets booked before we file.

  4. Half a double, one room bigger

    About 27% of Trafford houses are attached to a neighbor or split into two units. Owners of one half wonder whether they can add on at the back without touching the neighbor's side or the wall between them.

    How we build it

    Often yes, on your own lot and behind your own half. The new room stays clear of the shared wall's fire separation, and the roof is built so water runs off your side, not onto the neighbor's.

  5. A covered porch out back

    On the hillside streets, owners want covered space off the kitchen: a dry seat through a summer rain and a place for the grill, with steps down to a sloping yard.

    How we build it

    Porches and decks are on the borough's building permit form, so we file with a plot plan and drawings. Posts sit on footings, the roof is framed back to the house wall, and guards and stairs meet code where the ground drops away.

    Sunrooms and porches
  6. Close to the creek

    Brush Creek flooding keeps coming up at council from South Trafford. Owners down there still want space, and they ask whether adding on is allowed, or sensible, on their lot.

    How we build it

    The borough's zoning won't permit building or altering where a site floods from time to time, so the lot's history and the flood map come first. Where an addition fits, we may build up instead of out and keep it above the wet ground.

    What we check first

Homes and owners: Census Bureau, ACS 2020–2024, Borough of Trafford. Flood and shed rules: Trafford zoning, Chapter 202.

The rest of the job

How it runs, what it costs and who builds it are on our main additions & adus page.

Adding On in the Borough

Paperwork, the lateral testand land that floods.

Trafford additions pass through the code official's office, often run into the lateral test, and must clear a zoning rule most towns lack: nothing new on ground that floods.

  1. 24 hrsNotice to book an inspection

    The borough's paperwork

    Applications need a lot drawing, plans in duplicate and the deed; the sewage hookup is verified when the permit issues; and every inspection needs 24 hours' notice. The kitchen remodeling page for Trafford lists it all. We put the set together.

  2. $20,000Value that brings the sewer test

    The lateral test comes first

    Jobs over $20,000, or over $10,000 with two or more plumbing fixtures, require a leak test on your building sewer before the permit clears. Exemptions are listed on Trafford's attic finishing page, and we call Public Works early.

    The lateral test, explained
  3. §202-9No new building on flooded sites

    No building where it floods

    Trafford's zoning ordinance bars erecting or altering a building on a site that has experienced periodic flooding. Near Brush Creek, that one line can settle whether an addition goes ahead, so we ask the borough about your lot's record before drawing.

Addition Questions

Trafford additions,answered close to home.

What Trafford owners want settled first. Our main additions service page covers construction start to finish.

Ask a Question
[ 01 ]What does an addition in Trafford cost?

Size, foundation and plumbing decide it, plus anything the sewer test turns up. A plain room on a flat yard is the modest job; a hillside foundation, a new bath or fixing a leaking lateral raise it. After walking the lot together, we put a figure in writing.

Addition price ranges
[ 02 ]Could a parent live in a separate unit here?

Not in R-1, which allows single-family houses only. The R-2 district lists doubles and multifamily buildings, so a second unit there is a zoning question to settle first. A suite inside your own household sidesteps that, and the borough hears about it before we draw.

In-law suites
[ 03 ]Can the new shed out back have power?

No. Trafford's shed rules allow one per home, behind the house, at least 2 feet off the side lines, no bigger than 12 by 12 feet and 8 feet tall, and with no electric service. For lights and outlets, it has to be an addition or a garage instead.

Garage builds
[ 04 ]Do old mines run under Trafford?

Not according to DEP. Its subsidence map shows no confirmed mining within the borough, and the closest mapped area sits a third to half a mile beyond the line. Looking up your address before a big foundation is free and confirms it.

Check the state's mine subsidence map (opens in a new tab)
[ 05 ]What happens with the addition at sale time?

The borough issues an occupancy permit at every change of ownership, and it won't issue one without a current sewer lateral inspection. If the addition already set off the lateral test, that report counts for three years, which can save a step at closing.

“I couldn't recommend the All Trades team more! They did a wonderful job on the drywall and tile for a bedroom and bathroom remodel. They were responded to me quickly, were kind and easy to work with, efficient and attentive to detail. They checked in along the way to make sure we were on the same page about the project. I couldn't be happier with how it turned out!”

“My wife and I have been kicking around the idea to get our master bathroom remodeled for the last couple of years but never pulled the trigger. While getting a roof repair done due to some windstorms, I asked the gentleman for some bathroom remodel references and he gave me AllTrades contact info. I met with James and he was really good about understanding what we wanted to do. He allowed us to feel comfortable and confident in his teams ability to get us what we wanted. Once we agreed on the quotes (very detailed and broken down) the work started within days. This was a full gut and remodel which involved moving some plumbing and closing up a window and cutting in a new one on a different wall. The two gentleman doing the job were fantastic. Super nice and cordial to my whole family. Brison and Vinny, thank you for making my family feel safe while you were transforming our bathroom into a much more functional and beautiful space! This group does all kinds of work as isn't limited to just bathrooms. I recommend you at least speak to them and get some quotes for any work you are looking to get done.”
