Window replacement in a historic district needs the city's heritage preservation commission to approve the new windows before they go in, and what gets approved is a window that matches the original in size, operation, lite pattern and the profile of the sash and muntins. JMB Builders measures, prepares the drawings and specification for the application, and installs the approved windows across the Twin Cities metro. Send photos and we reply within one business day.
- Approval first, order second
- Match size, operation, lite pattern and profiles
- Priced per window, windows supplied
In a locally designated historic district, exterior changes that are visible from the street go through the city's heritage preservation commission or its staff before a permit is issued. Windows are the change they look at hardest, because the windows are most of what makes an old house read as old. Rules differ by city and by district; some allow replacement when the originals are beyond repair, some require matching materials, and most want the new window to match the old one in the ways you can see from the sidewalk.
What they look for is consistent. The new window should fill the same opening, with no blocked-down framing or filler panels. It should operate the same way: a double hung stays a double hung. The lite pattern should match, with true or simulated divided lites of the same number and layout, and the muntin and sash profiles should be close to the originals in width and depth, which rules out flat grilles between the glass. Material is the part that varies: many commissions want wood or clad wood on street elevations and are more flexible on the sides and rear. We photograph and measure the originals, pull a profile of the sash and muntins, and put together the drawings, cut sheets and photos the application asks for.
The order goes in after the approval, not before. Lead times on matching wood and clad windows are long, so the review adds a season to the project, and we tell you that up front. On install, the original interior trim and plaster stay where the commission and the condition of the frame allow an insert; where the frame is rotted, the full-frame unit is matched to the exterior casing and sill profile so the street view does not change. JMB Builders installs across the Twin Cities metro, in the older neighborhoods of Minneapolis, St. Paul and the first-ring cities where these districts are.

How it is priced: per window
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Wood or clad wood with simulated divided lites costs more than a standard replacement window
- Custom sizes and profiles to match the originals vs. a stock unit close to them
- Preparing the application drawings and specification, quoted as its own line
- Street elevations held to a higher standard than side and rear windows
- Insert vs. full-frame; rotted sills on a hundred-year-old house are common
- Window count and second-story access on a tall old house
Send photos from the street and tell us the district. We quote the windows and the application package as separate lines so you can see each.
How long it takes
The city review adds weeks to months before anything is ordered, then the factory lead time for matching wood or clad windows. Install itself runs two to four windows a day on an old house.

Situations and options
Clad wood double hungs with simulated divided lites
The most commonly approved replacement: wood inside, clad outside, SDL bars matched to the original muntin width with a spacer bar between the panes. Fills the original opening and operates the same way.
All-wood replacements on the street elevation
Where the district requires wood outside, a painted wood window matched to the original profile. More upkeep than clad, but what some commissions require on the front. Sides and rear can often be clad.
Street side matched, rear more flexible
Many districts review only elevations visible from the public way. The front and visible sides get the matched windows; the rear can take a simpler unit in the same color, where the guidelines allow.
Application package only
You want to handle the install later or compare bids, but need the drawings and specification for the commission now. We measure, trace the profiles and prepare the package as a standalone line.
Window Replacement in a Historic District — Getting the Approval: questions, answered
Do I need approval to replace windows in a historic district?
In a locally designated district, yes, for windows visible from the street and often for all of them. The city's heritage preservation commission or its staff reviews the proposed windows and issues an approval before the building permit. Each city writes its own guidelines, so the first step is finding out which district you are in and asking the city what it reviews.
What do heritage commissions look for in replacement windows?
A window that reads the same from the sidewalk as the original: same opening size with no filler panels, same operation, the same number and layout of lites, and sash and muntin profiles close to the original in width and depth. Grilles between the glass are usually rejected because they look flat. Material rules vary; wood or clad wood on street elevations is the common requirement.
Can I put vinyl windows in a historic house?
On the street side of a designated district, usually not; most guidelines call for wood or clad wood there. Some districts allow other materials on rear or non-visible elevations, and a house outside a designated district has no such rule even if it is old. We tell you what your district's guidelines say before you fall in love with a price.
How long does the historic review add to a window project?
Weeks to a few months, depending on whether staff can approve it or it goes to a commission meeting, and whether the first submission is complete. Then the factory lead time on matching wood or clad windows, which is longer than for a standard unit. Plan on the review adding a season, and start the application before you want the windows, not after.
Can the original interior trim stay when historic windows are replaced?
Often, yes. Where the old frame is sound, an insert window goes into it and the interior casing, stool and apron stay untouched. Where the sill is rotted, the frame comes out and the new unit is matched to the original exterior casing and sill profile so the street view is unchanged; inside, the original casing is reinstalled where it survives removal.
What goes in a historic window replacement application?
Photos of each existing window from the street and close up, measured drawings with the lite pattern, a tracing or dimensions of the sash and muntin profiles, and the manufacturer's cut sheets and specification for the proposed window showing size, operation, material, lite pattern and profiles. Some cities want a sample corner of the proposed window. We prepare that package; the owner files and signs.
