Custom Homes & Renovations in Abbotsford

Abbotsford covers 389 square kilometres, and the City says 72% of that land is in the Agricultural Land Reserve. So the first question on any Abbotsford project is which kind of land the lot sits on, before anyone draws a house.

We sort lots into three groups. Lots inside the City's Urban Development Boundary follow the normal zoning rules, and most of them can now hold more than one home. Farmland in the reserve follows provincial limits on house size that the City cannot raise. Hillside lots with slopes over 20%, on Sumas Mountain and around McKee Peak, need a geotechnical report before design. The Sumas Prairie floodplain adds its own rules on top of these.

The City's online WebMap shows the Urban Development Boundary and the zone for every property, and that is where we start each feasibility review.

The City's 2025 zoning update, summarised in January 2026, gave new houses more room. Single detached houses and duplexes can now be 9.5 metres tall everywhere in the city, up from 8.5 metres. Up to 30 square metres of an attached garage no longer counts toward the house's floor area, and floor area is now measured from the inside face of the outside walls. The City says plainly that these changes allow bigger buildings than before.

Secondary suites changed too. In most zones a suite used to be capped at 100 square metres. It can now be anything under half the size of the main home, so a 240 square metre house can hold a suite of up to 119 square metres. Infill houses also lost the rule that kept the upper floor to 80% of the floor below.

Inside the Urban Development Boundary, a lot of 280 square metres or less can hold up to 3 homes, and a larger lot up to 4, if the lot is under 4,050 square metres, has no heritage protection, and sits outside a Transit-Oriented Area. Coach houses are allowed in the SR, RS6-C, RCH and N30 zones, and garden suites in the RS3-ig, RS7 and N78 zones. The City's guide limits a garden suite or coach house to 15% of the lot, with a maximum of 100 square metres. Suites, garden suites and coach houses cannot be sold apart from the main house.

A single detached house needs 2 parking spaces, and each suite or coach house needs 1 more. The City also asks for a State of Title Certificate with the permit, because a covenant on title can block a plan that the zoning allows.

Bradner and Mount Lehman sit in the northwest corner of Abbotsford, an area of 65 square kilometres that the City describes as mostly farmland. On parcels there that are in the Agricultural Land Reserve, the Agricultural Land Commission's rules come first and the City's zoning second.

The Commission allows one main house of up to 500 square metres of total floor area without an application, as long as the fill placed for it covers 1,000 square metres or less. A suite inside that house is allowed. On parcels of 40 hectares or less, one extra residence of up to 90 square metres may be allowed when the main house is 500 square metres or less; on larger parcels the limit is 186 square metres. The City of Abbotsford can set tighter limits than these, and a bigger house needs a separate application to the Commission.

We plan farmland houses around those numbers from the first sketch. A family that wants a 600 square metre house on reserve land needs to know at the start that it means an application, extra time and an uncertain answer. Where a parcel is not on City sewer or water, the septic system and well are designed with the house, because the number of bedrooms affects the size of the septic system.

Sloped lots on the east side of the city need engineering work before design. If a property has slopes steeper than 20%, or sits within 20 metres of a steep slope, the City may require a Steep Slope Development Permit. That permit needs a geotechnical report that sets how far the house must stay from the top or bottom of the slope, a signed landslide assessment assurance statement, and an erosion and sediment control plan for clearing and grading.

The City's hazard guide records that in January 1935, repeated slides in the Kilgard Road area of Sumas Mountain swept ten homes down the mountain. The City's housing guide also says a development permit may be required for lots inside the McKee Neighbourhood Plan area.

On a sloped lot we bring the geotechnical engineer in before the architect finishes the plans, because the setbacks in the report often move the house. Driveway grade, retaining walls and drainage are priced at the same time as the house.

In November 2021 the Nooksack River overflowed into Sumas Prairie. The City calls it a 1-in-100-year event, and more than 1,100 properties and over 3,300 people were evacuated. In December 2025 the river overtopped its banks again, in what the City describes as a 1-in-35-year event, and 485 properties were placed under an evacuation order.

Properties inside the floodplain areas shown in Schedule E of the Zoning Bylaw must follow its floodproofing rules, including setbacks from watercourses. The City's zoning checklist asks the designer to show the height of the underside of the main floor, or the top of a slab on grade, for floodproofing. Where fill is used to raise the ground, the slope of that fill cannot extend into the setback area. We confirm the required floor height with the City before the house is designed, because it changes the foundation, the entry stairs and the driveway.

Abbotsford's Building Bylaw sets what goes in with a new house permit. Section 40 asks for lot grading plans, the minimum building and garage pad elevations, and driveway details. On an infill lot in an existing subdivision, it also asks for a current survey by a BC Land Surveyor and the depths of the storm and sanitary sewer connections at the property line. Under section 65, the City will not issue the permit without proof of home warranty insurance and a Licensed Residential Builder, or an owner builder declaration.

Energy rules apply to every new house. Since May 1, 2023, new homes must meet Step 3 of the BC Energy Step Code, and since March 10, 2025 the energy model must also report the home's greenhouse gas emissions (Zero Carbon Step Code level EL-1). The City asks for the energy model with the permit application and requires an airtightness test partway through construction, before the insulation inspection.

Clayburn Village is a heritage conservation area. The City says it holds houses, a schoolhouse, a church and a general store from the time of the Clayburn Brick Company. Building or renovating there needs a Heritage Alteration Permit, the City's approval for altering or developing property inside a heritage conservation area.

Clearbrook and West Abbotsford are two of the 22 communities in the City's 2024 neighbourhood profiles. On their lots inside the Urban Development Boundary, the city lot rules above apply: up to 4 homes on most lots, houses up to 9.5 metres tall, and larger suites than before.
