Wheelchair ramp permits depend on three things: whether you're building new or modifying existing structure, the total rise (height to overcome), and the materials and anchoring method. A temporary wooden ramp sitting on blocks might be exempt in some jurisdictions; a permanent ramp bolted to the house or integrated into the foundation almost always requires a permit. The IRC R105 gives building departments authority to require permits for accessibility modifications, and most states have adopted accessibility standards matching the ADA Accessibility Guidelines or ICC A117.1. What counts as "exempt" varies sharply by city — some treat ramps under 12 inches of rise as outside the permit scope; others require permits for any structural modification to a house. The safe move is a phone call to your local building department before you buy materials.
When wheelchair ramps require permits
The threshold that triggers a permit is the total rise — the vertical distance from the starting point to the ending point. Most jurisdictions exempt ramps with less than 12 inches of rise, since short rises don't trigger accessibility code requirements and are typically removable without permanent damage. But check your local code first — some jurisdictions have no rise exemption and require a permit for any ramp modification to a residential structure. If the rise exceeds 12 inches, or if you're anchoring the ramp permanently to the house (bolts into framing, footings dug below frost depth, attached ledger), a permit is almost certainly required.
Material and method matter enormously. A metal accessibility ramp from a supplier with pre-engineered specs and rubber feet is often easier to permit than a custom wood ramp, because the submittal package is thinner and structural design is already certified. Wood ramps require specification of lumber grade, fastening schedules, and railing details — more work for you and more scrutiny from plan review. Concrete footings anchoring the ramp below frost depth trigger additional requirements: frost depth varies by region (36 inches in most of the north, 12-24 inches in moderate climates, sometimes none in southern zones), so a ramp in Minnesota needs much deeper footings than one in Georgia.
The IRC R105 requires a permit for any building work that affects structure, egress, accessibility, energy efficiency, or safety systems. Wheelchair ramps affect accessibility (A117.1 slope and surface standards), egress (the ramp may be a required exit path), and sometimes structure (if you're cutting into rim board to install the ramp base). That's a permit trigger in almost every jurisdiction. The one honest exemption is temporary, fully removable ramps — no anchors, no bolts, just sitting on blocks or the ground with rubber feet — but even then, some jurisdictions require notification. Call first.
Slope is the next code checkpoint. The ADA Accessibility Guidelines and ICC A117.1 both require a maximum slope of 1:12 — that means 1 inch of rise for every 12 inches of run. A 12-inch rise needs 144 inches (12 feet) of ramp length minimum. Steeper slopes trigger handrail requirements, landing sizes, and structural scrutiny. Some older or site-constrained installations use steeper slopes and require an administrative variance or an ADA alteration exception, which adds 2-4 weeks to the process. If your site is tight, ask the building department upfront whether they'll accept a steeper slope under alteration rules or if you need a variance.
Handrails and guardrails depend on rise and run. Ramps with a rise of 6 inches or more, or a horizontal length of 72 inches or more, require handrails on at least one side per A117.1. Handrails must be 34-38 inches above the ramp surface, graspable (1.25-2 inches in diameter for a circular rail), and extend 12 inches beyond the top and bottom of the ramp. If the ramp is 30 inches wide or more, handrails are required on both sides. Guardrails (42 inches high, 4-inch sphere rule) are required when the ramp is 30 inches or more above the ground or has a drop-off. Plan review will check these dimensions carefully — they're safety-critical and visible to inspectors.
Landing requirements round out the code picture. A landing at the top and bottom of the ramp must be at least 60 inches by 60 inches, clear of obstacles, and sloped no steeper than 1:48 in any direction to prevent water pooling. If the ramp changes direction, a 60x60 landing is required at the turn. These landings eat up space quickly on constrained sites, which is why pre-design calls with the building department save money — you might learn that a slightly different ramp location avoids the need for an extra landing or a variance.
How wheelchair ramp permits vary by state and region
Northern states (Minnesota, Wisconsin, Michigan, Maine) require ramp footings to extend below frost depth — 36-48 inches in most cases — which adds significant cost and complexity. This explains why a 12-inch rise ramp in Maine might need 4-foot deep footings; that's the IRC R403.1 requirement for frostline protection. Southern states (Texas, Georgia, Florida) have little or no frost depth, so footings can be shallower or sit on-grade with proper drainage. Florida's 8th Edition Building Code adds wind-load requirements for ramps in hurricane zones (Design Wind Speed 130+ mph), which changes handrail materials, fastening schedules, and potentially the structural engineer's involvement. Expect longer review times in hurricane-zone states when the ramp is exposed to wind.
California's Title 24 energy code and broader accessibility standards (California Building Code Section A117.1 with amendments) sometimes impose stricter handrail and landing rules than the baseline IRC. Local jurisdictions in California (San Francisco, Los Angeles, San Diego) may also have accessibility requirements for public facilities that spill into residential permits if the ramp is part of a mixed-use or rental property. Confirm whether your project is classified as residential or commercial — it changes the code section applied.
Some states and cities have adopted the 2021 or 2024 IBC; others are still on 2015 or 2018. The differences are incremental (better drainage language, updated material specs), but they matter in plan review — cite the right code edition that your jurisdiction uses, or the reviewer will bounce the plan back asking for corrected calculations. Check your local building department website or call to confirm which IBC/IRC edition is in effect in your jurisdiction.
A handful of progressive jurisdictions (Seattle, Portland, Minneapolis, Boston) have policies encouraging accessible home modifications and streamline permits for ADA-compliant ramps — sometimes offering over-the-counter approval if you submit pre-engineered ramp specs from an approved supplier. Most others require standard plan review. If you're in a progressive-access jurisdiction, ask the building department whether they have an expedited or approved-product list for residential ramps.
Common scenarios
A removable wooden ramp, 12 inches of rise, rubber feet, no anchors
This is the gray zone that varies most by jurisdiction. Some cities exempt temporary, fully removable ramps under 12 inches of rise under the rationale that they're not structural modifications and can be removed without damage. Others require a permit for any ramp modification to a residential structure, even temporary ones. A few require notification but not a full permit. Call your building department and describe the setup: total rise, materials, how long it will stay, whether you'll anchor it. If they say "no permit," ask for that in writing so you have documentation if an inspector shows up later. Most likely: you'll get a straight answer in 2-3 minutes, and if a permit is required, it's a simple 15-minute filing.
A permanent wooden ramp, 18 inches of rise, 6x6 posts set in concrete footings 4 feet deep, 1:12 slope, handrails both sides
This is definitely a permit project. The 18-inch rise triggers accessibility code (A117.1), the concrete footings are permanent foundation work (IRC R403.1), the handrails are safety-critical elements, and the ramp is structurally attached to the site. You'll need a permit application, a site plan showing lot lines and the ramp footprint, a detail drawing of the ramp slope and handrail height, a footing detail showing depth and concrete strength, lumber grades for the framing, and fastening schedules. The building department will review for ADA/A117.1 compliance, frost-depth adequacy, structural safety, and code-edition match. Expect 2-3 weeks for standard review, $150–$300 in permit fees (most jurisdictions use 1–2% of estimated construction cost), and an inspection after concrete cures and before framing begins.
A prefabricated modular metal ramp, 8 inches of rise, manufacturer specs provided, fastened with bolts to the house rim board
The 8-inch rise is below the 12-inch threshold that triggers accessibility rules in some jurisdictions, but the permanent bolting to the house structure makes this a permit job almost everywhere. The bolts create a load path that affects the house rim board and potentially the foundation sill — that's structural modification under IRC R105. File a permit application with the manufacturer's spec sheet (which should include bolt sizes, spacing, and load ratings), a site plan, and a photo or sketch showing where the ramp bolts to the house. Because the ramp is prefabricated and engineered, plan review is typically faster — 1-2 weeks — and the fee is $75–$150. You'll need an inspection before bolting (to verify the rim board can accept the fasteners without shimming or cutting) and a final inspection after installation.
Replacing an existing wooden ramp with a new one in the same footprint, same materials, no change to slope or handrails
Like-for-like replacement might be exempt under the theory that you're not changing the scope or risk profile of the structure. But the building department will want to verify that the original ramp was permitted (check county records or ask the department) and that you're truly not modifying it. If the old ramp was never permitted and the new one will be visible or permanent, the department may require a permit on the replacement as an opportunity to bring the structure into code compliance. If the old ramp was permitted and your new ramp is identical, you might get an exemption — but call first. If anything changes (material, location, slope, handrails), it's a new project and requires a permit.
An interior ramp inside a residential living space to connect two different floor levels
An interior ramp is subject to the same IRC R105 and A117.1 rules as an exterior ramp. The slope, landings, handrails, and surface specifications all apply. Interior ramps also trigger egress review — the ramp might be a required exit path, which changes the slip resistance and surface material requirements. You'll file a permit application with floor plans showing the ramp location, slope, dimensions, handrail details, and the materials (flooring, handrail, subfloor). If the ramp requires structural support (posts, beams), include framing details. Expect 2-3 weeks for review and an inspection after the ramp structure is complete but before finishing.
A concrete ramp poured in place, 6 inches of rise, anchored to the existing concrete pad with epoxy bolts
Concrete ramps are always permitted projects because concrete is permanent, affects the site drainage and foundation, and requires structural design. You'll need a permit application, site plan, concrete design calculations (strength, reinforcement, finish texture for slip resistance), details showing the epoxy-bolt anchoring method, and slope verification (1:12 or steeper). If the ramp is more than 30 inches wide or the rise is more than 12 inches, handrail and guardrail details are required. Concrete ramps sometimes require a structural engineer's stamp, especially if the epoxy anchoring is unconventional or if the existing pad's condition is unknown. Plan for 3-4 weeks of review, $200–$400 in fees, and inspections at rebar placement, before pour, and after cure.
What to file and who can pull the permit
| Document | What it is | Where to get it |
|---|---|---|
| Permit Application | The building department's standard form requesting project description, owner info, contractor info (if applicable), estimated cost, and scope of work. Most departments have a one-page residential form. | Your local building department website, or in person at the permit office. Usually free; sometimes available as a fillable PDF. |
| Site Plan | A top-down drawing of your lot showing the house footprint, the ramp location, property lines, setbacks, and overall dimensions. Scale should be 1/8 inch = 1 foot or clearer. Include dimensions showing where the ramp starts and ends relative to the house and lot lines. | You draw it, or hire a surveyor or draftsperson ($100–$300). A hand-drawn, dimensioned sketch is acceptable if it's clear and to scale. |
| Ramp Detail Drawing | A side-view (elevation) and top-view (plan) drawing of the ramp itself. Must show total rise, horizontal run, slope (as a ratio, e.g., 1:12), handrail height (34-38 inches), landing dimensions (60x60 minimum), material specifications, and fastening details. For wood ramps, include lumber grades (e.g., 2x12 pressure-treated, #2 or better). For metal ramps, include the manufacturer name and model. For concrete, include design strength (psi) and reinforcement detail. | You draw it or hire a draftsperson. For prefabricated ramps, the manufacturer provides the drawing — submit that directly. |
| Footing or Foundation Detail (if applicable) | A side-view drawing showing how the ramp base connects to the ground. If digging holes and setting posts in concrete, show hole depth (must be below frost line for your jurisdiction), concrete strength, post size, and how the post connects to the ramp frame. If bolting to an existing structure, show bolt size, spacing, and the connection detail (rim board, siding removal, etc.). | You draw it, or a draftsperson/engineer. Frost depth for your state/region can be found in the IRC Table R403.3(1) or your state building code. |
| Manufacturer Specifications (for prefabricated ramps) | If using a commercial modular or prefab ramp, submit the spec sheet provided by the manufacturer. It should include slope, handrail details, load ratings, material specs, and fastening schedules. | The ramp supplier or manufacturer's website. |
| Structural Engineering Report (sometimes required) | For permanent ramps with unusual site conditions, custom slopes, or novel anchoring methods, the building department may require a signed and sealed report from a structural engineer. This includes load calculations, soil assumptions, and fastening verification. | Hire a PE structural engineer in your state. Cost is $500–$2,000 depending on scope. Most engineers will require a site visit and your ramp drawings. |
| Property Survey (sometimes required) | If you're unsure of exact property lines or setbacks, a recent survey ($300–$600) prevents disputes. Some jurisdictions require it; most accept a reasonably accurate site plan you draw yourself. | A licensed surveyor in your state. Check county deed for setback requirements first — many don't need a full survey. |
Who can pull: The homeowner can always pull a permit. If you hire a contractor to build the ramp, the contractor may pull the permit on your behalf — confirm in the contract whether they'll do this or whether you'll file. If a structural engineer is required, they typically submit the permit application along with their report, but you still sign as the project owner. If an electrician is involved (rarely, unless the ramp includes integrated lighting), they may file a separate subpermit for electrical work.
Why wheelchair ramp permits get bounced back
- Site plan missing property lines or setback dimensions
Redraw the site plan to include the lot perimeter, property-line distances from the house, the ramp location relative to property lines, and distances to driveways or adjacent structures. The plan reviewer needs to verify you're not encroaching on a neighbor's lot or violating local setback rules. A simple tape-measure sketch with dimensions is sufficient. - Ramp slope calculation is incorrect or missing
Clearly label the total rise (vertical distance) and total run (horizontal distance) on your elevation drawing, and state the slope as a ratio (1:12 is 1 inch rise per 12 inches run). The reviewer will recalculate to verify A117.1 compliance. If you're proposing a steeper slope, note that and explain whether you're requesting an alteration variance or ADA exception. - Handrail height or details not specified
On your ramp detail drawing, dimension the handrail height (must be 34-38 inches above the ramp surface per A117.1), specify the rail diameter (1.25-2 inches for circular), and show how much it extends beyond the top and bottom of the ramp (12 inches minimum on each end). Include material and fastening details. - Footing depth does not meet frost-line requirements
Check your state or local code for minimum footing depth (IRC Table R403.3 lists frost depths by region). If your jurisdiction requires 48-inch footings and you've drawn 36-inch, increase the depth or add a note explaining why shallower is acceptable (e.g., no frost-heave risk because the ramp is fully removable). Most reviewers will reject if you're below code without justification. - Code edition cited does not match the jurisdiction's adopted code
Call the building department and ask which edition of the IBC and IRC they use (e.g., 2015 IBC + 2015 IRC with state amendments). Re-cite your submittal with the correct edition. Code references matter for consistency during plan review. - Application incomplete: missing owner signature or contractor license number
Use the building department's current permit form and fill out every required field. If the form asks for a licensed contractor's name, include their state license number. If you're the builder, write 'Owner-Builder' and confirm whether your jurisdiction requires an owner-builder affidavit or license. - Landing dimensions do not meet 60x60 minimum requirement
A117.1 requires a minimum 60-inch by 60-inch landing at the top and bottom of every ramp. If your site is constrained, redraw the ramp to show compliant landing sizes, or request an alteration variance. Reviewers will reject if landings are undersized and no variance is noted. - Ramp material specifications are too vague
For wood ramps, specify lumber grade (e.g., 'pressure-treated 2x12, Graded #2 or better per NLGA or SPIB standards'). For concrete, specify design strength (e.g., '3,000 psi concrete'). For metal, give the manufacturer name and model. Vague language like 'standard lumber' will be rejected.
Wheelchair ramp permit costs
Permit fees for wheelchair ramps typically run $50–$500 depending on the estimated construction cost and your jurisdiction's fee schedule. Most building departments charge 1–2% of the valuation (estimated total cost of materials and labor). A simple removable ramp might be valued at $200–$500 and trigger a $50–$100 permit fee. A permanent ramp with concrete footings, handrails, and structural design might be valued at $3,000–$8,000 and trigger a $150–$300 fee. A few jurisdictions charge a flat fee ($75–$125) regardless of valuation. Over-the-counter processing (same-day or next-day approval for straightforward projects) is standard at many smaller departments; plan review for complex projects takes 2–4 weeks and sometimes costs a separate plan-review fee ($50–$100).
| Line item | Amount | Notes |
|---|---|---|
| Standard permit fee | $50–$300 | Usually 1–2% of project valuation. Flat fees ($75–$150) are common in some jurisdictions. |
| Plan review fee (if separate) | $50–$100 | Not all jurisdictions charge separately; some bundle it into the permit fee. |
| Inspection fee (if separate) | $0–$100 | Some jurisdictions include inspections in the permit fee; others charge $50–$100 per inspection. |
| Structural engineer (if required) | $500–$2,000 | Needed for complex, non-standard ramps. Simpler prefab ramps usually don't require engineering. |
| Architectural or drafting services | $100–$500 | If you need a draftsperson to draw the site plan and ramp details. Often unnecessary if you're submitting prefab ramp specs. |
| Survey (if required) | $300–$600 | Rarely required unless property lines are disputed or setbacks are tight. Most jurisdictions accept a hand-drawn site plan. |
Common questions
Can I build a wheelchair ramp without a permit if I keep it temporary?
Depends on your jurisdiction and how you define temporary. Some cities exempt removable ramps (no anchors, sitting on rubber feet) under 12 inches of rise. Others require a permit for any structural modification, even temporary ones. A few require notification but not a full permit. The safest approach: call your building department, describe the setup (height, materials, how long it will stay, whether you'll anchor it), and get an answer in writing. If they say no permit is required, keep that email for documentation. If a temporary ramp stays for years, the building department may eventually require retroactive permitting.
What's the difference between a ramp and a landing or deck?
A ramp is an inclined plane with a slope between 1:20 (5% — barely noticeable) and 1:12 (8.3% — standard accessibility). Steeper and it's no longer a ramp; flatter and it's not achieving the rise fast enough. A landing is a horizontal platform at the top or bottom of a ramp (or between ramp runs) — it must be 60x60 inches minimum and slope no steeper than 1:48. A deck is a raised platform without the incline; decks are usually exempt under certain square-footage thresholds (often 200 square feet or less), but ramps are not — ramp permits depend on rise and attachment, not area. If you're building a deck and adding a ramp to it, both elements are reviewed under their respective rules.
Do I need handrails on every ramp, or only long ones?
Handrails are required per A117.1 if the ramp rises 6 inches or more, or the horizontal run is 72 inches (6 feet) or more. If both conditions are true, handrails are definitely required. If only one is true (e.g., a short ramp with a 6-inch rise but only 72 inches of run), handrails are still required. For a ramp 30 inches wide or more, handrails are required on both sides. For narrower ramps, one handrail is sufficient. The handrail must be 34–38 inches above the ramp surface, graspable (1.25–2 inches diameter for a circular rail), and extend 12 inches beyond the top and bottom of the ramp. These are safety-critical and the plan reviewer will check them closely.
What's the deepest I need to dig footings for a ramp?
Footing depth depends on your region's frost line — the depth below which soil does not freeze and heave. The IRC Table R403.3(1) lists frost depths by state and sometimes by county. Most northern states (Minnesota, Wisconsin, Michigan, Maine) require 36–48 inches; moderate climates might be 24–36 inches; southern states sometimes have no requirement. Frost heave occurs when soil freezes and expands, pushing the foundation (or ramp posts) upward, which causes cracks and misalignment. If you're setting ramp posts in concrete footings, the bottom of the footing must be below the frost line. If the ramp is fully removable (no footings, just rubber feet), this doesn't apply. Check your local building code or call the building department for your specific frost depth.
Can I use wood for a ramp, or does it have to be concrete or metal?
Wood is a perfectly acceptable ramp material and is very common in residential work. You'll need to specify pressure-treated lumber (to prevent rot), a lumber grade (#2 or better is typical), and fastening schedules. The ramp surface (the walking surface) must have a slip-resistant finish — a textured coating or adhesive safety strips are standard. Handrails can be wood or metal. Footings can be concrete (if below frost line) or metal posts set in concrete. The review process is slightly more involved than for prefabricated metal ramps because the reviewer needs to verify your lumber specs and fastening, but it's routine. Wood ramps are usually cheaper upfront and blend visually with residential neighborhoods.
How long does a wheelchair ramp permit take to get approved?
Simple, straightforward permits (prefabricated metal ramps with manufacturer specs, no site constraints) can be approved over-the-counter in 15 minutes to a day if you have all the documents. More typical permits take 1–3 weeks for plan review. Complex projects (custom wood ramps, structural questions, footings near property lines, requests for variances) can take 3–4 weeks or longer. Time varies by jurisdiction size, current workload, and code edition. Call your building department and ask their typical review time when you submit your application.
Do I need a building permit if I'm just replacing an old ramp with a new one?
If the old ramp was permitted and your new ramp is identical (same footprint, same slope, same handrails, same materials), you might qualify for a like-for-like exemption. Check county permit records to see if the old ramp was permitted. If it was, and you're truly not changing anything, call the building department and ask whether a permit exemption applies. If the old ramp was never permitted, the new ramp might require a permit as an opportunity to bring the structure into code. If anything changes (height, slope, location, material, handrails), it's a new project and requires a permit. The safe move: call the building department before you start. Most will give you a straight answer in a few minutes.
What happens if I build a ramp without a permit?
If an inspector or neighbor reports the ramp, the building department will issue a stop-work order and require you to either obtain a retroactive permit (you'll file all the paperwork as if it's new, with the ramp already built, and it may be rejected if it doesn't meet current code) or remove it. Retroactive permits sometimes cost more than advance permits because they're investigative in nature. If the ramp fails inspection (slope too steep, handrails missing or the wrong height, footings too shallow, surface too slippery), you'll be required to fix it at your expense — potentially a bigger cost than the permit would have been. Inspectors are not looking for ramps specifically, but they become visible during other property work, renovations, or routine neighborhood checks. Unpermitted ramps can also complicate property sales or insurance claims. Getting the permit upfront is cheaper and faster than fixing an unpermitted ramp after the fact.
Do I need to hire a contractor to build a ramp, or can I do it myself?
You can absolutely build a ramp yourself. Homeowners are legally allowed to do their own construction work in most states. You'll still need to obtain the permit (as the owner-builder) and pass inspection, but you don't need to hire a contractor unless you want to. If you're hiring a contractor, confirm in the contract whether they'll pull the permit or if you will. Some states or jurisdictions require owner-builders to file an owner-builder affidavit or take out a license depending on the contract value; ask your building department. If a structural engineer or electrician is involved, they may pull their own subpermit.
What if my ramp slope ends up steeper than 1:12 because my space is tight?
If you can't fit a 1:12 ramp due to site constraints (short lot depth, existing obstacles, near property line), you have a few options. Request an ADA alteration exception — the ADA allows steeper ramps (up to 1:8) when the site is truly constrained and no other solution exists. This is not a permit rejection; it's a code variance request that the building department evaluates. Alternatively, you can design a longer ramp (more run to achieve the rise at 1:12), add switchbacks or turns, or raise the landing point (if that's safe). A steeper slope also triggers additional handrail and landing requirements, which increases cost. Call the building department early in your design to discuss what's feasible in your specific situation — they might approve an exception or steer you toward a compliant solution that works for your space.
Next step: Call your local building department
The fastest way to know if you need a permit is a 3-minute phone call to your building department. Describe your ramp (total rise, material, how you'll anchor it, whether it's temporary or permanent) and ask whether a permit is required. Ask for the fee, the typical review timeline, and what documents they'll need. Get the name of the person you speak with and keep notes — if they say no permit is required, email them a summary and ask them to confirm in writing. Most building departments have this conversation dozens of times a year and can give you a clear answer fast. If they say a permit is required, ask for their permit application form and their online portal (if they have one). Ask about over-the-counter vs. plan-review timelines — many straightforward ramps don't need full review and can be filed and approved in an hour. If your site is complex or you're unsure about code details, hire a local draftsperson or structural engineer for 1-2 hours to help you prepare the submittal — it's cheaper than rework after rejection.
