Condo Window Replacement: What Changes in a Condominium

Association Approval and Architectural Standards
In a house you pick the windows. In a condo you usually ask first. Your bylaws may give the association control of exterior appearance, and in one Michigan appeals case nobody disputed the association's power to require a uniform door color. Troy's Building Department also recommends checking with your association before window work. Ask the management company or board for the window standard in writing: frame color, grille pattern, operating style and sometimes the brand and series. Submit it with the installer's quote attached, so the board approves the exact product you're buying.
Replacement windows are made to measure, so a unit the board rejects after delivery can't simply go back.
Unit Owner vs Association Responsibility
Michigan's Condominium Act leaves most of this to the master deed. A unit is the part of the project "described by the master deed". Everything else is a common element, and limited common elements are the parts the master deed reserves for some owners, such as one unit's balcony or, if the deed says so, its windows.
So the answer depends on your documents. In one Michigan Court of Appeals case, the master deed listed "unit perimeter walls (including windows and doors therein)" as common elements and made the association responsible for maintaining, repairing and replacing them. Other deeds can draw the line differently. Read the deed and bylaws before you get quotes. Who pays usually decides who signs the contract and who the installer answers to.
Matching Color, Grille and Series
A building looks wrong with one odd window. The things that have to match are the exterior frame color, the grille pattern (and whether grilles sit between the glass or on the surface), the sash proportions, and the trim or capping outside. Matching is easiest when you know the brand and series already on the building. If the association has a standard, it may name them.
If only a few units are being done, ask whether the series is still made. A discontinued line means either a close match approved by the board or a building-wide change sooner than planned.

Townhome vs Mid-Rise Condo Units
The building type changes the rules. A townhome-style condo of up to three stories, each unit with its own exit, falls under the residential code, so it's built and permitted much like a house. A stacked building with shared corridors falls under the building code instead, the same code as other commercial and multifamily work.
It changes the logistics too. Townhome windows are usually reached from the ground or a ladder. Upper-floor windows in a mid-rise may need a lift, interior access through the unit, or work from a balcony. Ask how each opening is reached before you compare prices. Bedroom windows in townhome units bring one more code point. The code's sill-height relief for replacement bedroom windows applies there (see egress window installation), so ask the installer to confirm it on the quote. For building-wide jobs, see commercial window replacement.
Insurance Certificates and Building Access
Ask your manager whether they need the installer's certificate of insurance before work starts, and who should be named on it. Pass that to the installer when you book, not the week of the job, so the start date doesn't slip.
Access rules matter too: parking for the truck, use of elevators or common hallways, protection for shared floors, working hours and where old windows go. Put them in writing with the approval.

Lead Paint in Older Troy Condos
A condo built before 1978 is housing like any other under EPA's lead rule, so anyone paid to replace its windows must be a certified lead-safe firm. If you rent your unit out, the rule also covers work you do yourself. See lead-safe window replacement.
