Usually not right up to it. Most zoning codes require a side setback, and many also restrict roof overhangs and gutters that cross toward the line.
What decides it:
- Zoning code: side and rear setbacks for your district and for the type of structure.
- Fire and building codes: buildings very close to a line may need fire-rated walls and limits on openings.
- Plat building lines and HOA rules [1].
- Easements along the line, which often prohibit structures [2].
Even where a small setback is allowed, leave a little extra room. Construction tolerances and roof overhangs add up.
Confirm the rules with your permit office, and have a licensed surveyor locate the line before you pour footings close to it.
