The Short Answer
Like-for-like window replacement in the same opening is exempt in Medina. But if you're in a historic district, replacing a basement egress window, or enlarging the opening, you'll need a permit.
Medina treats true like-for-like window replacement — same opening size, same operable type, same sill height — as exempt work, which saves you permit fees and timeline. But Medina's historic-district overlay (covering parts of downtown and older neighborhoods) requires pre-approval of window replacement before any work starts, even for same-size swaps, because the city enforces period-appropriate profiles, materials, and glazing patterns. Additionally, Medina applies Ohio's egress-window rules strictly: if your basement bedroom window has a sill more than 44 inches above the floor, or if you're touching a basement egress opening at all, the replacement must meet current egress sizing (per IRC R310), which often triggers a permit. Finally, Medina's adoption of the 2023 International Energy Conservation Code (IECC) means new windows must meet U-factor minimums for climate zone 5A (roughly 0.30 for most units); if your replacement windows don't meet that spec, the city may flag them during a future inspection or appraisal. Check your property's historic-district status first — that's your biggest wild card.

What happens if you skip the permit (and you needed one)

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

Scenario A
Same-size vinyl window replacement in non-historic single-family home (Medina Township)
You live on an acre in Medina Township (outside the city corporate limits, so no historic district) and want to replace three single-hung aluminum windows in your 1970s ranch with new vinyl double-hungs. The openings are exactly the same size: 36 inches wide x 48 inches tall, sill height 30 inches above the floor (well clear of any egress threshold). You're not touching the exterior wall structure, not changing operable type, not altering egress. This is a classic exempt swap. You can hire a contractor, order the windows (any reputable brand with U-factor 0.30 or better), and proceed without a permit. The contractor will remove the old frames, install new vinyl units, caulk, and trim out. No inspection required. Total cost: $3,000–$5,000 for labor and materials; zero permit fees. Timeline: 1-2 days of work. The key reason this avoids a permit: the city code keys on 'same opening, same operable type' — and Medina Township applies the same exemption as the city. No special certificate needed.
No permit required (same opening, same type) | U-factor 0.30 minimum (check spec sheet) | Tempered glass N/A (not near door or tub) | $3,000–$5,000 total project cost | Zero permit fees
Scenario B
Same-size window replacement in historic-district Victorian (downtown Medina)
You own a 1890s Victorian on East Liberty Street in downtown Medina's historic district and want to replace four double-hung wooden windows on the front facade. The windows are the same size (30 x 50 inches each), and you're keeping double-hung operation — but the existing frames have a muntin pattern (6-over-6), and modern vinyl replacements won't match that divided-light look. Even though the opening size is identical, Medina's historic overlay requires a Certificate of Appropriateness (COA) before any window replacement. You submit photos and specifications to the Medina Historic Preservation Commission, showing that your new windows are period-appropriate vinyl (with simulated divided lites to match the original 6-over-6 pattern), and that the frame color is a neutral off-white. The Commission approves in 3 weeks (a typical timeline for windows). Once approved, you can order and install without a building permit for the window replacement itself — the COA is your approval document. However, some contractors may ask for a simple $50 exemption permit just to have a paper trail; this is optional but prudent. Total cost: $4,500–$7,000 for four vinyl windows plus installation; $0–$50 permit fee (exemption only, optional); $0 COA fee. Timeline: 3 weeks for COA review, then 1-2 days for installation.
Certificate of Appropriateness required (historic district) | Period-appropriate profile and muntin pattern mandatory | 3-week COA review | Building permit optional ($50 exemption) or not required | $4,500–$7,000 total project cost
Scenario C
Basement egress window replacement — sill height over code limit (residential remodel)
You're finishing a basement bedroom in your 1960s ranch in Medina and discover the existing small horizontal slider window has a sill height of 46 inches — two inches above the 44-inch egress maximum. You want to replace it with a proper egress window (minimum 5 square feet of clear opening, sill no higher than 44 inches). The new opening will be the same width (36 inches) but must be taller to drop the sill. This is an opening-size change and a code-compliance trigger, so a permit is required. You submit a one-page permit application ($150–$200 fee) and specify the new egress window (e.g., Andersen or Marvin, 36 x 50 inches, clear opening 5.7 sq ft, sill at 42 inches). The city approves in 1 week and schedules a framing inspection (to verify the header is properly sized for the slightly larger opening) and a final inspection (to check sill height, clear opening size, and operational function). You'll also need an egress window well (about $400–$800 for materials and labor) if the window is below grade. The contractor does the installation and calls for inspections. Both pass. Total cost: $2,000–$3,500 for window, well, and installation; $150–$200 permit fee; 2-3 weeks total timeline (1 week permit review, 1-2 days for framing and final inspection). This scenario is common in Medina because many older homes have substandard basement windows, and homeowners often discover the issue only when finishing a bedroom.
Permit required (opening size change + egress upgrade) | IRC R310 egress compliance (5.7 sq ft clear opening, sill ≤44 inches) | Egress well required if below grade | Framing + final inspection | $150–$200 permit fee | $2,000–$3,500 total project

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.
