Home Additions in Metro Detroit: what to expect
An addition adds new square footage: a bump-out, a family room off the back, a primary suite, a bigger kitchen, or a second story over a ranch or bungalow. It is often the answer when you love your neighborhood but need more room.
Additions touch every part of a house. The new foundation must match or tie into the old one, the roof has to join cleanly without creating leaks or ice dams, and the heating and electrical systems may need upgrades to handle the new space. Zoning setbacks and lot coverage decide how big you can go.
Second-story additions are the most complex because the existing foundation and walls must carry new loads, which usually means an engineer. Ground-level additions are simpler but need footings below frost depth and careful drainage around the new foundation.
What a proper job includes
- A zoning check for setbacks and lot coverage
- Drawings and engineering where required
- Foundation, framing and roof tie-in to the existing house
- Windows, siding and roofing matched to the house
- HVAC, electrical and plumbing extensions by licensed trades
- Insulation to current energy code
- Building permit and inspections through final

- Foundation type: basement, crawl space or slab
- Roof tie-in complexity

Permits and licensing in Michigan
Additions require a building permit with drawings reviewed under the Michigan Residential Code. In Detroit, permits and inspections go through BSEED; elsewhere, the city or township building department (or the county or state, where they enforce) issues them. Electrical, plumbing and mechanical work is done by separately licensed contractors under their own permits.
Michigan licenses residential builders and maintenance and alteration contractors through LARA under Article 24 of the Occupational Code. A license is required for paid residential work above a threshold set by state law. Under the Michigan Construction Lien Act, your contractor gives you a sworn statement listing subcontractors and suppliers when requesting payment. Collect lien waivers as each is paid.
