What happens if you skip the permit (and you needed one)
- Installing windows in a historic district without pre-approval can trigger a stop-work order and fines of $250–$500 per window; the city may require you to remove and reinstall with approved materials, costing $2,000–$8,000 extra.
- A basement egress window that doesn't meet IRC R310 sill height or opening size can void your home's certificate of occupancy and block a future sale — inspectors flag it during title work, and lenders won't close until it's fixed.
- If your replacement windows don't meet IECC U-factor, your home-energy audit or refinance appraisal may red-flag the windows as non-code-compliant, delaying or tanking the transaction.
- Neighbor complaints about unpermitted work in a historic district can prompt a code-enforcement investigation; fines start at $250 and accrue daily until corrected.
Medina window replacement permits — the key details
Medina's core rule is simple: if your window replacement doesn't change the opening size, frame type, or egress status, and you're not in a historic district, no permit is required. This aligns with Ohio's adoption of the 2023 International Residential Code, which exempts like-for-like window swaps. However, Medina's City Code adds a wrinkle: if your property is within the historic district (roughly bounded by Market, Norwalk, Myrtle, and Public Square, with smaller overlays near the courthouse), you must submit a Certificate of Appropriateness (COA) application to the Medina Historic Preservation Commission before purchasing or installing replacement windows. The COA review takes 2-4 weeks and costs nothing, but it's a hard requirement — the city has cited homeowners for window replacement without it. The reason: Medina is serious about preserving its late-1800s and early-1900s character, and windows are a visible, protected element. Modern vinyl replacements that don't match the original muntin pattern, frame profile, or glazing depth are often rejected on first submission.
Egress windows in basements are Medina's second big trap. Ohio adopted IRC R310, which requires basement bedrooms to have an emergency escape window with a clear opening at least 5.7 square feet (or 5 square feet for existing basements), a sill height no more than 44 inches above the floor, and a window well (if below grade) with ladder or steps. If you're replacing an existing basement egress window with a same-size opening, that's typically exempt — you're not making the egress worse. But if the old sill is already 45 inches or higher (a common problem in older Medina homes), the city may interpret any touching of that window as an opportunity to bring it into compliance. When in doubt, call the Building Department before you order windows. If you do need to upgrade to a proper egress window, expect an $800–$2,000 cost for the larger window, well, and installation, plus a $150–$300 permit.
Medina adopted the 2023 IECC, which sets U-factor minimums for your climate zone 5A. Typical approved U-factors are 0.30 for fixed or single-hung units; some manufacturers offer 0.27 for high-performance units. Vinyl frames dominate the market in Medina, and most big-box stores now stock units that meet this standard, but a super-cheap big-box replacement or an old salvage window will not. The city doesn't typically inspect window U-factors during routine final inspections for exempt work, but if you're refinancing, applying for a home-energy rebate, or if an inspector notices single-pane glass, you may face a flag. To be safe, buy windows with a U-factor spec sheet and keep it with your permit file — or submit a simple one-page permit for even like-for-like work if you're worried about future scrutiny.
Tempered-glass rules also matter in Medina. Any window within 24 inches of a door opening (per IRC R612) or above a bathtub must be tempered or laminated. This is an old rule, but Medina enforces it during inspection. If you're replacing a window in a bathroom over a tub or near a shower door, or a window next to an entry door, order tempered glass — it costs about $50–$150 extra per window and is worth the peace of mind. The city won't issue a final approval if you miss this.
The practical path: First, check if your property is in the historic district by calling the Medina Planning Department at 330-764-1600. If yes, start with the COA application (free, online at the city's website or in person). If no historic overlay, and your window is same-size and not egress-related, no permit is required — just hire a contractor, replace the window, and save the receipt. If you're unsure about egress compliance or U-factor, spend 20 minutes and a phone call to the Building Department; they're usually helpful and can give you a yes/no answer over the phone. If you do need a permit, expect $100–$250 for one to three windows, and a final inspection within 2-3 weeks.
Three Medina window replacement (same size opening) scenarios
Historic district windows in Medina — how the COA review really works
Medina's Historic Preservation Commission is one of the most active in Summit County, and windows are their top priority. The Commission meets the third Thursday of each month and reviews COAs for window replacements, reroofing, siding, and other exterior work. Your application must include a color photo of the existing window, a product spec sheet for the replacement (showing frame color, profile depth, muntin pattern, and glazing type), and a one-paragraph explanation of why you're replacing it (age, damage, energy efficiency). The Commission favors vinyl windows with simulated divided lites over modern single-pane units, and they want frame colors to match the original — typically white, off-white, cream, or (rarely) dark green or black if documented. Modern bronze or 'terratone' vinyl is almost always rejected on first submission.
Common rejections include: frame too deep (modern frames are often 1 3/4 inches, whereas 1800s frames were 1 5/8 or even 1 3/8 — a visual difference that matters), wrong muntin count (8-over-8 instead of 6-over-6), exterior trim profile doesn't match, or color is too bright white. Resubmission adds 2-4 weeks. To save time, many contractors now work with local suppliers who stock Andersen 400 or Marvin Infinity windows in profiles that Medina approves — ask your contractor if they have a 'Medina-approved' spec sheet. The COA costs $0 and doesn't require a building permit; it's purely a design review. Once approved, you can install immediately without waiting for a building permit.
One insider tip: if you're replacing windows in the rear of the house (not visible from the street), the Commission is much more lenient — they may approve modern single-hung vinyl units in any color, since the 'historic fabric' concern is lower. If you're replacing street-facing windows, budget extra time and be prepared to use simulated divided-light vinyl. Call the Medina Planning Department (330-764-1600) before you order windows; staff can often predict whether your choice will pass COA without a formal submission, saving you weeks and a reorder.
Egress windows and the 44-inch sill trap — why Medina enforces it strictly
Medina is glacial-till country, and many of its 1950s-1980s homes were built with minimal basement egress — small horizontal sliders pushed high on the wall to reduce drafts and ease framing. The problem: those windows often don't meet IRC R310 egress minimums (44-inch sill height, 5 square feet clear opening). When homeowners try to finish a basement bedroom, they suddenly discover they need an egress window, and the existing sill is too high. Medina's Building Department, following Ohio code, will not sign off a basement bedroom certificate of occupancy without compliant egress. This is non-negotiable — it's a life-safety rule, and code officials have seen the consequences of narrow egress windows in fires.
If you're replacing an existing basement window that's already non-compliant, the replacement must meet current code — so you'll need a permit and inspection. The cost jump is real: a compliant egress window (30-36 inches wide, at least 40-50 inches tall) runs $400–$800, plus a window well ($400–$800) and installation labor. Some homeowners balk at $2,000–$3,000 for a bedroom egress window, but Medina won't cut corners. If your current window is compliant (sill at or below 44 inches, opening at least 5 sq ft), then a same-size like-for-like replacement is exempt. Call the Building Department (330-764-1600) to confirm your existing window's sill height and opening size before you decide — it's a five-minute conversation that saves you thousands.
A second wrinkle: some older Medina homes have basement windows installed in foundation walls without proper wells or grades. If the window is more than 12 inches below exterior grade, a well is required. During a window replacement, the inspector will check this. You can't exempt yourself from well installation by claiming you're just replacing glass — the opening itself triggers the requirement. Budget accordingly, and don't be surprised if the city asks you to excavate and install a well as a condition of the egress window permit.

Common questions
Do I need a permit to replace windows in my Medina home?
It depends on three factors: (1) Is the opening the same size? (2) Are you in a historic district? (3) Is it an egress window? If the opening stays the same size, you're not in a historic district, and it's not an egress window, no permit is required. If you're in a historic district, you need a Certificate of Appropriateness (COA) from the Planning Department before replacing windows, even if the opening is the same size. If it's an egress window, call the Building Department to confirm sill height and opening size — if either is non-compliant, a permit is required.
What is a Certificate of Appropriateness (COA) and how long does it take?
A COA is a design-review approval from Medina's Historic Preservation Commission for exterior work in the historic district. For windows, you submit a photo of the existing window and a spec sheet for the replacement; the Commission reviews it at their monthly meeting (third Thursday of the month). Typical approval takes 3–4 weeks if your window choice matches the Commission's standards (simulated divided lites, appropriate color). If you choose a window that doesn't match the historic character, they'll ask for resubmission, adding 2–4 weeks. The COA costs nothing and does not require a separate building permit.
My basement window sill is 46 inches high — do I need a permit to replace it?
Yes. Ohio code (IRC R310) requires basement egress windows to have a sill no higher than 44 inches. If your sill is 46 inches and you're replacing the window, the city will interpret that as an opportunity to bring it into compliance, so a permit is required. You'll need to install a larger window (typically 36 inches wide x 50 inches tall) with a sill at 42 inches or lower, plus a window well. Permit fee is $150–$250, and the total project cost (window, well, installation) is $2,000–$3,500.
Can I use single-pane glass for a bathroom window replacement?
Not if the window is within 24 inches of a door opening or directly above a bathtub or shower. Per IRC R612, those windows must be tempered or laminated glass. Check your bathroom layout before ordering windows. Most manufacturers stock tempered-glass units for this application — the cost is $50–$150 extra per window.
What is a U-factor, and does my replacement window need to meet a specific standard?
A U-factor measures how much heat flows through a window; lower is better. Medina adopted the 2023 IECC, which requires a U-factor of roughly 0.30 for windows in climate zone 5A. Most new vinyl windows sold at big-box stores meet this standard, but older or salvage windows will not. Check the product spec sheet before ordering. If you're refinancing or applying for an energy audit, the window's U-factor spec may be requested, so keep the documentation.
My contractor says we don't need a permit for same-size window replacement. Is that true?
True — if the opening size doesn't change, the window is not an egress window, and the property is not in a historic district. However, verify these three points yourself: (1) Measure the existing opening width and height; (2) Check if your address is in the historic district (call Planning at 330-764-1600 or check the city's GIS map online); (3) If it's a basement, check the sill height (must be 44 inches or lower for no-permit replacement). If all three check out, no permit is required. If any is unclear, call the Building Department for a quick phone call.
How much does a window replacement permit cost in Medina?
$100–$250 for one to three windows, depending on whether the opening size changes. Same-size replacements in non-historic homes don't require a permit, so zero cost. Historic-district COAs cost nothing. If the opening size increases or an egress window is required, the permit is typically $150–$200 plus the cost of any required inspections (usually bundled into the permit fee).
What if I'm in a historic district and just want to replace the glass, not the frame?
If you're replacing only the glass and keeping the original wood or aluminum frame, a COA is generally not required — the Commission is focused on frames, profiles, and visible exterior elements. However, if the original frame is damaged or deteriorated as a result of the glass replacement, the Commission may ask about frame repair or replacement. Check with Planning if you want to be certain; a quick call can clarify. Most homeowners find it safer to submit a COA application and avoid any future code-enforcement issues.
How long does it take to get a window replacement permit in Medina?
For a same-size, non-historic-district replacement: no permit required, so same-day work is possible. For a historic-district COA: 3–4 weeks (reviewed at monthly Commission meeting). For an egress-window or opening-change permit: 1 week for city review, then inspection scheduling; total 2–3 weeks. If you're in the historic district and also changing the opening size, allow 4–6 weeks (COA review + permit review).
What happens during a final inspection for a window replacement permit?
The inspector checks that the window is operationally sound (opens and closes smoothly), that the sill height meets code (if egress), that the opening size and clear-opening measurements are correct, that tempered glass is used where required (within 24 inches of a door or above a tub), and that the window is properly sealed and caulked. For most single-window jobs, the inspection is visual and takes 10–15 minutes. If the opening size changed, the inspector will also verify that the header is properly sized and supported. Once passed, you'll receive a final approval letter for your permit file.
