Good to know
Addition or remodel?
- An addition makes sense when the rooms you have cannot be reshaped into what you need.
- A remodel is often simpler if there is unused space, such as a basement or attic, that could be finished instead.
- Lot size, setbacks and zoning limit how far and how high a house can grow.
- Compare the two in our guide: should you build an addition or remodel?

FAQ
Additions questions, answered
Do I need a permit to build an addition?
Yes, almost always. Additions change the footprint and the systems of the house, so expect a building permit and inspections. Zoning and setback rules apply too. Your partner contractor confirms what your address requires.
How long does an addition take?
Longer than most interior projects, because it includes design, permits, foundation work and weather. A partner can give a realistic schedule once they see your lot and plans.
Can I live in the house during construction?
Usually yes, since most of the work happens outside the existing walls. Expect noise, dust and a few days when the new space is connected to the old one.
What is the best time of year to build an addition?
Exterior work generally goes smoothest in the warmer months, but planning, permits and ordering can start any time. Starting those in winter can put you in line for spring.
