For hardscaping in Uxbridge, the Township's Site Alteration By-law is usually the rule to understand first, because most patios, walkways and walls start by digging out soil and reshaping the ground. Michael Durham Landscaping builds interlock and natural stone patios, walkways, steps and retaining walls for Uxbridge homes, and we repair and seal interlock that is already in place.
How We Build a Patio or Walkway
Our interlocking and hardscaping service uses natural stone or concrete pavers on the same base every time:
- Six inches of engineered aggregate, placed and compacted in three separate lifts, so the stone above it stays flat through Ontario winters.
- Water planned before stone. We work out every slope and swale so runoff heads away from the house.
- Polymeric sand in the joints, which binds the pavers and keeps out weeds and ants.
- Edge restraint along the borders so the pattern cannot creep.
- Full commercial liability insurance on every hardscape job.
A typical residential patio is 3 to 5 days of work, from digging out to sweeping in the polymeric sand. When a project includes retaining walls, plan on a week or longer.
What the Township of Uxbridge Requires
Moving soil: the Site Alteration By-law
Uxbridge's Site Alteration and Fill Permits page says you need a permit before you remove topsoil, bring in fill or change the grade of land, unless the work is exempt. The consolidated Site Alteration By-law 2010-084 lists the exemptions. Two matter most for a backyard project:
- Spreading soil for lawn dressing, landscaping or garden beds needs no permit if the ground rises by no more than 20 centimetres, drainage toward neighbouring properties does not change in any significant way, the work stays at least 60 centimetres from every property line, and the total stays under 50 cubic metres a year.
- Other site alteration under 50 cubic metres of soil on a lot in a year is also exempt on the same drainage and 60 centimetre conditions, unless the site includes or borders a body of water.
The by-law also limits when site alteration can happen: not between 7 p.m. and 7 a.m. on weekdays, only from 8 a.m. to 3 p.m. on Saturdays, never on Sundays or statutory holidays, and not during an Environment Canada wind warning or within 24 hours of precipitation. Stricter limits apply on parts of the Oak Ridges Moraine (Natural Core, Natural Linkage and some Countryside Area lands), in Environmental Protection zones and on former pits or quarries. The by-law does not apply in areas regulated under the Conservation Authorities Act.

Building permits
The Township's Building and Construction page lists what does and does not need a building permit. A deck under 24 inches off the ground does not. An attached deck or raised porch does when it has a roof or stands higher than 24 inches, and so does a pergola, trellis or gazebo over 15 square metres. Replacing a deck completely needs a permit even on the same footprint, and the new one must meet current zoning. If you are trading an old deck for a ground-level stone patio, ask the Building Division how that change is treated.
Retaining walls do not appear on that list. Under the Ontario Building Code, a wall over 1 metre of exposed height next to public property, a building entrance or a space the public can use is a designated structure that needs a permit. For our retaining wall work, we check at the quote and handle the application when one is needed.
Pools, grading and property lines
A patio around a pool sits inside the rules of the Township's Fence By-law 2012-119. The Pool Enclosure Permits page says a permit is needed before installing or digging for a pool, and the enclosure work and final inspection must be finished within six months. The by-law sets the enclosure at no less than 1.2 metres high and no closer than 1.2 metres to the water's edge, with self-closing, self-latching gates.
The same by-law says owners must not alter the natural grading and drainage swales of their property, and that no site alteration may take place within 60 centimetres of a property line. It also excludes retaining walls from its definition of a fence, so the fence height limits do not set the height of a wall.
Historic downtown
The Township's Heritage Planning page says buildings and storefronts must follow the Heritage Impact Assessment and Heritage Conservation Plan Guidelines in By-law 2021-019, and that these guidelines affect patios, fences and landscape features. It calls patios welcome downtown and points to wood, stone and wrought iron as historic materials. Natural stone often suits those properties better than modern pavers.
Homes on septic
Many rural Uxbridge homes rely on a septic system. Durham Region's Health Department approves septic systems for the Township and runs a maintenance inspection program for older systems near lakes, rivers and streams in the Lake Simcoe watershed. Its Sewage and Septic Systems page explains how current owners can request septic records, though it holds nothing before 1974. Know where your tank and leaching bed are before you sketch a patio.
Rules change. Confirm current requirements with the Township of Uxbridge Building Division before work begins.
Common Questions
Do I need a fill permit for a patio in Uxbridge?
Often not, but check. Moving less than 50 cubic metres of soil on a lot in a year is exempt when drainage to the neighbours does not change in any significant way, the work stays 60 centimetres from property lines and the site does not include or border a body of water. Bigger grade changes need a Site Alteration Permit.
Can a patio replace my old deck without a permit in Uxbridge?
A deck under 24 inches high needs no building permit, and a full deck replacement does. A ground-level patio is not on the Township's permit list, but zoning and the Site Alteration By-law still apply, so ask the Building Division about your plan.
How close to the pool can the stone go?
The Fence By-law keeps the enclosure at least 1.2 metres from the water's edge and at least 1.2 metres high. Plan the patio layout so the enclosure and its self-closing, self-latching gate still meet those distances.
Do you repair or seal interlock in Uxbridge?
Yes. We repair and seal existing interlock as well as building new. Describe the problem in your quote request and we will inspect it on site.
