The question most landowners ask is the wrong one. Instead of "do I need a permit?" the better question is: "Do I need an engineered drawing — and if so, at what level?"
These are different questions with different answers. A permit may be required for work that doesn't require professional engineering. Some work requires neither. And some work is entirely outside city jurisdiction by operation of Ohio law.
This article breaks down each tier.
Tier 1: No Permit, No Drawing Required
Ohio Building Code Section 105.2 exempts certain work from permit requirements entirely. Strongsville follows the Ohio Building Code and applies these state-level exemptions. Work that does not require a permit in residential zones includes:
Landscaping and gardening:
- Planting trees, shrubs, ground cover, flowers, vegetables, or native plants
- Removing grass and installing garden beds
- Mulching, composting, and soil amendment on your own property
- Rain gardens and bioswales that do not tie into the public storm system
- Installing native meadow or prairie plantings
Minor grading and earthwork:
- Topsoil application (spreading soil on the surface)
- Regrading lawn areas where drainage does not direct water onto neighboring property or into streets
- Installing swales for on-site drainage management that stay within your property
Small structures:
- Portable structures (no foundation) with a footprint under 200 sq ft — this is the Ohio Building Code threshold for permit exemption (OBC § 105.2.1)
- Playground equipment, garden art, temporary shelters
- Trellises, garden fencing under 7 feet high (some municipalities have stricter rules — verify with the Strongsville building department, as city fencing ordinances may impose lower height limits or setback requirements)
Trail improvements:
- Installing mulch or wood chip trails on private property
- Placing stepping stones
- Installing wooden foot bridges that are not engineered structures over water
Tree work:
- Pruning branches below a certain height (verify Strongsville's tree preservation ordinance, which has its own permit trigger for trees above certain caliper)
- Removing dead limbs and storm damage
- Note: Strongsville has a Tree Preservation Plan under Section 1138 that may require a separate tree removal permit for certain trees — this is a zoning review, not a building permit
Tier 2: Permit Required — Applicant-Drawn Sketch Acceptable
For many small-scale projects, Strongsville will issue a permit based on a clear, dimensioned sketch drawn by the applicant — not a professionally stamped engineering drawing. This applies when:
- The project is simple, clearly described, and within standard code parameters
- The work does not involve structural engineering calculations
- Grading is minor and drainage does not present a public impact concern
Examples of permit-required, sketch-acceptable projects:
- Accessory structures from 200–600 sq ft (a small shed or storage building) — simple plan showing dimensions, setbacks from property lines, and basic materials
- Fences (if over the city's permit threshold) — drawing showing location, height, and materials along property lines
- Paved driveways and parking pads — showing impervious surface area and drainage direction
- Retaining walls under 4 feet in height (Ohio Building Code exempts walls under 4 feet from the engineered drawing requirement, but a site sketch is still often required for permit)
- Decks and patios under a certain size threshold
What your sketch must show:
- Property boundaries and dimensions (from your deed or survey)
- Location and footprint of the proposed work, measured from property lines
- Direction of drainage / any nearby waterways or drainage features
- Any existing structures that are relevant to setback calculations
- North arrow and scale
You do not need an architect's seal or a professional engineer's stamp for these sketch permits. A hand-drawn diagram that clearly shows dimensions and location is sufficient.
Tier 3: Permit Required — Licensed Designer Drawing Required
Projects that involve structural calculation, significant grading impact, or utility connections require a drawing prepared or reviewed by a licensed professional:
Structural work:
- New construction of any habitable structure
- Additions to existing buildings
- Structural repairs (replacing load-bearing elements)
- Bridges, elevated walkways, or platforms over certain height or span
Significant grading:
- Grading that involves moving more than a threshold volume of soil (varies by municipality — Strongsville's engineering department handles grading permits for substantial work)
- Grading within a setback or near property lines that could direct drainage to adjacent properties
- Any grading within a mapped floodplain
- Drainage connections to public storm infrastructure
Utility work:
- Electrical service panels, new service entry, or buried utilities
- Plumbing connections to the municipal system
- HVAC systems in structures
For these projects, "engineered" means:
- An architect, professional engineer (PE), or licensed designer prepares the drawings
- Drawings are stamped with the designer's license number and seal
- The designer takes legal responsibility for the design meeting code
Tier 4: Engineering Required — Professional Stamped Plans
The highest tier requires a licensed professional engineer's stamped site plan before any permit will be issued:
- New impervious surface over a certain threshold connecting to public storm drainage — Strongsville's engineering department will require stormwater management plans
- Retaining walls over 4 feet — structural engineering required
- Bridges or creek crossings — Army Corps and Ohio EPA may additionally require separate permits; a PE stamp is required for structural design
- Any site development affecting a FEMA floodplain — elevation certificates and PE-stamped grading plans
- Major grading projects — typically defined as moving more than a certain cubic yardage (consult with Strongsville Engineering at 440-580-3120 for the current threshold)
- Utility installation or tie-in — electrical, plumbing, and gas work requires licensed contractor drawings
A full engineered site plan from a civil engineer typically costs $2,000–$8,000 for a residential-scale project in northeast Ohio. At the higher end, with surveys, environmental review, and structural engineering, costs can exceed $15,000.
The key question: Before committing to engineering costs, confirm with the Strongsville building department exactly which tier your project falls into. Many landowners assume Tier 4 applies when Tier 2 or 3 is actually sufficient.
What you can do on your land without city interference
The following activities are not regulated by Strongsville's building or zoning codes — they are matters of private property rights and are not subject to permit requirements:
Ecological restoration:
- Removing invasive species
- Planting native trees, shrubs, wildflowers, grasses, and ground covers
- Installing compost, leaf mulch, or wood chip material
- Creating brush piles and habitat features for wildlife
Soil management:
- Amending soil with compost, leaf material, wood chips
- Manual or small-equipment grading that stays on-site and doesn't redirect drainage
- Soil testing and sample collection
Water management on private land:
- Rain garden installation (vegetated, on-site retention)
- Installing a rain barrel or cistern
- Managing surface water that stays within your property boundaries
Agricultural and horticultural activities:
- Growing vegetables, fruits, herbs, and flowers for personal use
- Beekeeping (Strongsville allows up to 4 hives with a zoning permit — verify current code)
- Composting organic material
- Growing native plant nursery stock for personal planting on-site
Private trails and informal paths:
- Establishing walking trails on your own property
- Installing stepping stones, log steps, or informal surface materials
- Creating trail markers and small signs
Tree work within certain parameters:
- Removing hazard trees with no storm drain or right-of-way impacts
- Pruning and maintenance within your property (Strongsville's Tree Preservation Plan applies to trees over a certain caliper on developable lots — confirm with the city for your specific situation)
The bottom line for vacant lot owners
If your project falls in Tier 1 — gardening, native planting, trail installation, rain garden, soil amendment — no permit is required and no drawing is needed.
If your project is in Tier 2 — a small structure, fence, or simple grading — a permit is likely required but a hand-drawn sketch is typically all you need for the application. The permit cost is usually under $200 for small accessory work.
Before spending money on engineering, call the Strongsville Building Department at 440-580-3110, describe your project specifically, and ask: "What tier of documentation is required for this work?" Get the answer in writing. The investment in that conversation is zero. The investment in an engineering firm you didn't need is not.
