Frontenac ARB Renovation Approval: What Reviews Come First?

A buyer closes on a Frontenac lot in July. The contractor is lined up, the architect has stamped drawings, and everyone agrees on a September groundbreak. Then the plans hit a wall nobody warned them about at closing: the property sits inside a subdivision with its own Board of Trustees, and the city's Architectural Review Board will not even look at the project until those trustees sign off first.

That's not a hypothetical. It's how Frontenac's review process is built, and it catches buyers who assume a building permit is a single conversation with the city rather than a sequence with its own private gatekeeper standing in front of the public one.

Two boards, not one

Most homeowners picture permitting as a straight line: submit plans, city reviews them, city approves or asks for changes. In Frontenac, if your property is part of a subdivision governed by a Board of Trustees, that assumption breaks down immediately. The city's own Architectural Review Board page states plainly that if a property sits within a subdivision with a Board of Trustees, the ARB will not vote on the item until the trustees have reviewed the project first. The public board is waiting on the private one.

That means your actual approval sequence has two stops before a permit is even in play: your subdivision trustees, then the city's Architectural Review Board, which handles applications that touch a structure's exterior architectural features. Skip ahead of the trustees, and the ARB simply won't take up your item, no matter how complete your drawings are.

Why the ARB's calendar matters more than your contractor's

Here's the part that turns a paperwork detail into a real timeline risk. The Architectural Review Board meets only twice a month, the first and third Thursday, at 8:30 a.m. at City Hall. It also will not vote on a project without full construction plans in hand. No partial sets, no conceptual sketches held over for the next meeting to finalize.

Miss a meeting because your trustee review ran long, or because one page of your plan set wasn't finished, and you're not waiting a few days. You're waiting roughly two weeks for the next scheduled session, sometimes longer around holidays. Add the trustee review ahead of it, and a project that looks like a six-week runway on paper can easily stretch past two months before a permit application is even reviewed.

Once the ARB does approve a project, city staff note that an initial building permit review typically follows two to three weeks later. That's on top of the review sequence above, not instead of it.

Here's roughly how the sequence stacks up for a typical addition or new build in a trustee-governed subdivision:

A buyer who plans their closing, financing, and contractor schedule around only the last two rows is planning around half the actual process.

What the board is actually judging

The Architectural Review Board isn't rubber-stamping paperwork. Its stated purpose, spelled out in the city's code, is to determine whether a new structure or an expansion will conform to good standards of architectural appearance, stay in general harmony with the style and character of the surrounding structures, and avoid being disharmonious or unsuitable next to what's already there. That's a judgment call, not a checklist, which is part of why complete plans matter so much walking in.

Lot size plays into this too. Frontenac's R-1 Residence District carries a one-acre minimum, while R-2 is 7,500 square feet minimum. On the larger R-1 lots especially, additions and rebuilds tend to be substantial enough that they visibly change how a house reads from the street, which is exactly the kind of project the ARB is set up to weigh carefully against its neighbors.

Landscaping isn't an afterthought either. The city's tree preservation and landscaping standards require at least one canopy tree for every 100 feet of street frontage, and any project disturbing more than an acre needs landscape plans reviewed and approved by a landscape designer or licensed landscape architect retained by the city. If your renovation involves regrading a yard or clearing mature trees along a frontage street, that's a separate review track layered on top of the architectural one, with its own drawing requirements covering tree locations, removals, and replacement plantings.

If your plans don't fit the envelope

Sometimes a project doesn't fit neatly within setback or zoning rules as written. That's what the Zoning Board of Adjustment is for. It hears variance requests, most of which start when the Building Commissioner denies a permit application for not meeting current zoning. The application fee is $250, and the applicant also covers the city attorney's fee for the hearing and the court reporter's fee for transcribing it.

From a complete variance application, the process generally takes about 30 days. Neighboring property owners get mailed notice, and a sign goes up on the property ahead of the hearing. It's a public process by design, which means it adds visibility and time that a straightforward ARB review doesn't require.

Building your calendar backward, not forward

None of this means a Frontenac renovation is unreasonably slow. It means the planning has to start from the finish line and work backward, rather than starting from a contractor's open week and hoping the reviews keep pace.

A permit, once issued, is valid for six months. If the project runs long, the Building Official can extend it, but only if the applicant requests it in writing and the city agrees the project has been diligently pursued, and there's a fee attached to that extension. Construction itself is also bound by set hours: 8 a.m. to 6 p.m. Monday through Friday, 9 a.m. to 5 p.m. on Saturday, and no work at all on Sunday. Those hours don't change your total timeline, but they do change how many actual working hours fit inside it.

For anyone buying a Frontenac property with renovation or rebuild plans already sketched out, the smart move is a short conversation with the city's building and planning staff before writing an offer, not after closing. Confirming whether a specific subdivision has an active Board of Trustees, and what that board's own review timeline typically looks like, tells you far more about your real start date than any contractor's estimate can.

If you're comparing a renovation against a full rebuild on a Frontenac lot, that decision carries its own set of tradeoffs worth walking through before you commit to either path.

FAQ

Does every Frontenac property have a subdivision Board of Trustees? No. Some subdivisions have an active trustee structure with its own architectural review authority, and some don't. This is one of the first things worth confirming with the city and with subdivision documents before assuming your timeline.

What happens if plans change after the ARB approves them? The board's role is to review complete construction plans as submitted. Material changes after approval typically mean going back through review rather than proceeding on the original approval, so it's worth locking design decisions before the meeting rather than after.

Can I request a specific ARB meeting date to hit a schedule? The board meets on a fixed twice-monthly schedule, first and third Thursday. Projects are heard as they're ready, so the practical lever is making sure your plan set and any required trustee sign-off are complete well ahead of the meeting you're targeting, not requesting a different date.

Does a simple interior remodel go through the ARB? The board's review is tied to exterior architectural features. Interior-only work that doesn't touch the exterior generally follows the standard building permit process without an ARB step, though it's still worth confirming with city staff for your specific scope.

None of this is meant to make a Frontenac renovation sound harder than it is. It's meant to make the calendar honest from the start, so a September groundbreak stays a September groundbreak instead of a surprise.
