Concrete driveway extension in Pittsburgh
A concrete driveway extension is often the simplest way to gain a parking space. We add a strip or pad next to your slab and tie the two together, so that they move as one and don't drift apart.
Check the rules first
Before you plan on a wider driveway, find out what your lot allows. Many towns limit how much of a front yard can be paved, how close a slab can sit to a property line and how wide a curb cut can be. If you only widen the driveway on your own lot and leave the apron alone, the review can be simple. If it means a wider cut at the street, that's a separate permit.
Watch out for storm water too, since extra pavement sends extra runoff somewhere. A neighbor's yard is the wrong answer, so we plan the slope with that in mind.
Tying new concrete to old
A strip poured against an old slab will separate or sink unless it's tied in. These are the details that stop that from happening.
- A clean saw-cut edge on the old slab
- Steel dowels drilled and set into the existing slab
- The same base depth as the rest of the driveway
- Joints that line up with the existing ones
- A sloped finish that sends water away from the house
Will it match?
New concrete is lighter than old concrete, and it'll stay that way for a few years. If that bothers you, a band of contrasting finish can make the change look intended, or you can tint the whole driveway with a sealer. If the old slab is near the end of its life, it may be smarter to do the whole thing at once through concrete driveway replacement.

Do I need a permit for a driveway extension?

Do I need permission to widen my driveway?
Usually, if it changes the street access or runs close to a property line. HOA homes may need board approval too.
Do I need a permit to widen my driveway with pavers?
Pavers may be treated the same as concrete. Ask your zoning office, since rules vary by town.
Do I need a permit to widen my driveway with gravel?
It's often the same as for concrete, and many towns count gravel as paved surface too.
How far from property line can I build a garage?
That depends on zoning for your lot. Driveways and garages each have their own setbacks, so check with your town.
