Home Additions in Troy: questions.
How much should a home addition cost in Troy, MI?
Ground-level additions in Oakland County run $200 to $350 per square foot; second-story and primary-suite additions run $300 to $450 per square foot including structural engineering. Sunrooms and screened additions are lower at $150 to $250 per square foot depending on how they are conditioned.
How long does a home addition take in Troy?
A ground-level room addition runs 4 to 6 months from permit to completion; second-story additions and primary suites run 5 to 8 months. Permitting at Oakland County municipalities adds two to six weeks before we break ground.
Do you pull permits for home additions in Troy?
Yes, on every job. The City of Troy Building Department is one of the more efficient in the county, with residential permits often turning around in one to three weeks. We pull every permit.
What is the difference between a build-out and a build-up addition?
A build-out expands the ground-floor footprint into the yard; a build-up adds a second story or expands an upper level. Build-outs are generally less expensive per square foot because the foundation work is simpler. Build-ups require engineering the existing structure to carry the added load but leave the yard intact — the right call on tight lots.
