Additions built to tie into the house you have.

Overview

Frequently Asked Questions

Will an addition match my house?

That is the goal: rooflines, siding, trim and window styles chosen to match what is there. It gets planned before the permit drawings are final.

Do I need zoning approval for an addition?

Only if the addition breaks the town's zoning rules, such as setbacks or lot coverage. Then the owner applies to the zoning board of adjustment for a variance under N.J.S.A. 40:55D-70, before the construction permit.

What does an addition cost?

It depends on size, foundation and what goes in it. The home addition cost guide has the Middle Atlantic Cost vs. Value figure. Your estimate is free.
