What a General Contractor Actually Does
A general contractor coordinates a construction project: scoping the work, pulling permits, scheduling and supervising subcontractors, ordering materials, managing inspections, and delivering a finished result. On a remodel they are the single point of accountability across trades that would otherwise need to be managed individually. That coordination role is what homeowners underestimate. A kitchen remodel touches demolition, framing, plumbing, electrical, HVAC, drywall, tile, cabinetry, countertop, flooring, and paint. Sequencing those correctly, so that each trade arrives when its predecessor is finished and inspections happen at the right moments, is most of the job. General contractors either self-perform some trades or subcontract all of them. Both models work. What matters is that the contract identifies who is responsible and who carries insurance. On smaller projects, homeowners sometimes act as their own general contractor. It is legal in many circumstances but it means owning the scheduling, the permit responsibility, the liability, and the problem when two trades disagree about whose work caused a defect.
Older Housing and What It Changes
Metro Detroit's housing stock is old, and remodeling an older home carries categories of risk that do not exist in newer construction. Budgeting a remodel here without a contingency is a planning error. Lead-based paint is the most consequential. Federal rules require that firms performing renovation, repair, or painting that disturbs covered painted surfaces in housing built before 1978, or in child-occupied facilities, be certified and follow specific work practices. A large share of Metro Detroit housing predates 1978, so this applies routinely rather than exceptionally. Asbestos-containing materials appear in older flooring, adhesives, pipe insulation, textured coatings, and siding. It cannot be reliably identified by appearance, and the EPA recommends assessment by a properly trained and accredited professional before renovation disturbs suspect material. Knob-and-tube wiring, ungrounded circuits, and undersized electrical service are common finds. Opening walls frequently reveals electrical that must be brought current before the wall closes. Galvanized supply and cast iron drain lines behave the same way described on our plumbing pages — once a wall is open, existing plumbing that cannot support the new fixture load becomes part of the project. Plaster and lath rather than drywall changes demolition and patching methods. Balloon framing in some older homes changes how fire blocking and structural modifications are handled. Settled foundations mean out-of-level floors and out-of-plumb walls. Cabinetry, tile, and trim all require scribing and adjustment that adds labor.
The Remodeling Process
Design and scope come first. The clearer the scope before work begins, the fewer change orders later. Scope changes made after demolition are the single largest driver of budget overrun. Contract and permitting follow. The contractor should pull the permits, and the enforcing agency depends on jurisdiction — Michigan enforcement may be state-administered or delegated locally. Demolition exposes the actual conditions. This is where older-home surprises surface, and where a well-written contract has already established how change orders are priced and approved. Rough-in follows: framing changes, then plumbing, electrical, and mechanical inside the walls. Rough inspections happen before anything is covered. Insulation and drywall close the assembly. Finish work — flooring, cabinetry, countertops, trim, paint, fixtures — is the longest visible phase and the one where quality differences show. Final inspection and punch list close the project. Retain final payment until the punch list is complete and the work has passed inspection.
Permits and Inspections
Most structural, electrical, plumbing, and mechanical work in a remodel requires permits. Cosmetic work generally does not. Confirm the enforcing agency for your address before work begins. Requirements and fee schedules vary across the six-county metro. Separate trade permits are common — a building permit plus electrical, plumbing, and mechanical permits, each with its own inspection. Historic district review applies in a number of Metro Detroit communities and can govern exterior changes, window replacement, and material selection. Confirm before designing. Unpermitted work surfaces at resale and can require opening finished assemblies to demonstrate compliance. It is significantly cheaper to permit correctly the first time. The contractor pulling the permit is the normal arrangement. A contractor asking the homeowner to pull permits on licensed work is shifting liability, and it is a common signal of a licensing gap.
Budgeting and Contingency
Cost is driven by scope, finish level, structural complexity, and how much of the existing house has to be corrected along the way. Finish level can swing a project's cost by multiples on identical square footage. The same kitchen layout executed with stock cabinets and laminate versus custom cabinets and stone is not the same project. Structural changes — removing a load-bearing wall, adding an opening, altering a roofline — require engineering and add cost well beyond the demolition itself. Bringing existing systems current is the line item most often omitted from initial budgets. Electrical, plumbing, and insulation upgrades discovered at demolition are real costs. A contingency of meaningful size is not pessimism on an older Metro Detroit home; it is planning. Projects that reserve nothing end up with either a budget crisis or a compromised finish. Payment schedules should track progress. A reasonable deposit followed by draws tied to completed milestones is standard. Large upfront payments are a warning sign.
Contracts and Change Orders
The contract should specify the scope in detail, the materials and allowances, the schedule, the payment terms, the change order process, the warranty, and how disputes are handled. Allowances are a frequent source of conflict. An allowance is a placeholder budget for a selection not yet made — tile, fixtures, cabinets. Allowances set unrealistically low make a bid look competitive and produce overruns later. Ask what the allowance actually buys. Change orders should be written, priced, and signed before the work is performed. Verbal change orders are the most common source of end-of-project disputes. Lien rights matter. Subcontractors and suppliers in Michigan have lien rights, which means a homeowner can face a lien even after paying the general contractor if the general did not pay downstream. Waivers of lien collected with each draw protect against this, and they are standard practice. Warranty terms should distinguish workmanship from manufacturer coverage on installed products. Read what you sign. A remodel contract is a significant legal document and the moment to raise questions is before signing, not at the punch list.
Living Through It
Decide up front whether you are staying in the house. Kitchen and whole-house projects are substantially harder to live through than a single bathroom or a basement. Establish dust containment expectations in the contract. Older-home demolition generates significant dust, and lead-safe work practices in pre-1978 housing impose specific containment requirements. Agree on working hours, site access, bathroom use, parking, and where materials and debris will be staged. Expect the schedule to move. Inspection scheduling, material lead times, and discovered conditions all shift timelines, and a contractor who never adjusts a schedule is usually not communicating rather than never encountering issues. Establish a single point of contact and a regular check-in cadence. Most remodel conflicts are communication failures rather than workmanship failures. Document progress with photographs, particularly of concealed work before it is covered.
Choosing a General Contractor
Verify licensing. Residential builders and maintenance and alteration contractors are licensed in Michigan through LARA, and verification is public and quick. Confirm liability and workers' compensation insurance directly with the carrier. For pre-1978 homes, confirm the firm holds current lead-safe renovation certification. This is a federal requirement for firms disturbing covered painted surfaces in that housing, not an optional credential. Ask for references from projects of similar scope completed in the last two years, and ask specifically about how change orders and problems were handled — not just whether the homeowner was happy. Ask who is on site day to day and who supervises. On smaller firms it is the owner; on larger ones a project manager. Either is fine if you know. Compare scopes rather than headline prices. Bids that differ substantially usually differ in what is included, in allowance levels, or in assumptions about existing conditions. Rebuild Detroit presents and verifies provider information. Rebuild Detroit does not perform remodeling work — the licensed contractor you select is responsible for the work, its permits, and its warranty.

Frequently Asked Questions
Do I need a permit to remodel my house?
For structural, electrical, plumbing, and mechanical work, generally yes. Cosmetic work usually does not require one. Requirements vary across the six-county metro and Michigan enforcement may be state-administered or locally delegated, so confirm the enforcing agency for your address.
What is the lead paint rule and does it apply to my house?
Federal rules require firms performing renovation that disturbs covered painted surfaces in pre-1978 housing to be certified and follow specific work practices. A large share of Metro Detroit housing predates 1978, so it applies routinely here. Confirm your contractor holds current certification.
How much contingency should I budget?
On an older Metro Detroit home, a meaningful reserve is planning rather than pessimism. Opening walls in a house built decades ago frequently reveals electrical, plumbing, or structural conditions that must be corrected before the wall closes.
What is an allowance and why does it matter?
It is a placeholder budget for a selection not yet made — tile, fixtures, cabinets. Allowances set unrealistically low make a bid look competitive and produce overruns later. Ask specifically what each allowance actually buys before comparing bids.
Can a subcontractor put a lien on my house if I already paid?
Yes. Subcontractors and suppliers in Michigan have lien rights, so a homeowner can face a lien if the general contractor did not pay downstream. Collecting waivers of lien with each payment draw is standard practice and protects against this.
Should I act as my own general contractor?
It is possible on smaller projects but it means owning the scheduling, permitting, liability, and the disputes between trades. On a project involving multiple trades and inspections in an older home, most homeowners find the coordination cost exceeds the savings.
