Home Renovations in Langley, BC

A whole-home renovation usually touches more than one room and needs more than one trade: walls moved or taken out, a new kitchen, new bathrooms, new floors, a finished basement, new wiring and plumbing, and sometimes new windows or an addition. As the general contractor, we hold the contract with you and the contracts with the trades. Plumbers, electricians, framers, drywallers, tile setters and finishers all work to one schedule that we set.

Our part starts before any drawing. We visit the house and check which municipality it is in, how old it is, whether it is on sewer or septic, and what its zone allows. Then we coordinate the designer and, where the structure changes, the engineer who seals the plans. We apply for the building permit, and the licensed electrician applies for the electrical permit through Technical Safety BC. During the work we book each inspection, and the next stage starts after the previous inspection passes. You get daily logs, schedules and live budget updates during the job.

Parisian Elements, in the photos below, is a whole-home renovation we finished in Rosemary Heights, Surrey. The work covered the main floor and the basement and took 6 months. We did it in two phases so the owners could keep living in the house.

If you need one room done, see our page on bathroom renovations in Langley. We take bathroom-only jobs.

The Township's renovation guide (January 2025) says a building permit is needed to alter, repair, renovate, move or add to a house, to finish a basement or build a secondary suite, to install new plumbing fixtures or re-arrange piping, to build a chimney or put in a wood stove, and to build a retaining wall over 1.2 m tall. Electrical and gas permits come from Technical Safety BC.

Applications go in online. The guide asks for a title search no older than 30 days, a site plan that shows any rights-of-way, easements and watercourses, scaled drawings, plans sealed by a structural engineer where the structure changes, a soil declaration and an erosion and sediment control form. The Township's checklist for additions and alterations also asks for the contractor's business licence number, and for a tree cutting and removal declaration on land outside the Agricultural Land Reserve. On a septic lot, a Registered Onsite Wastewater Practitioner (ROWP) adds the Fraser Health paperwork.

Inspections are booked online through a MyTownship account by 3:30 pm on the business day before. The Township does not promise next-day visits, and the business licence number of the trade doing the work goes in the booking notes. Once the permit is issued, and before any work starts, an inspector checks the waste bins, the tree protection fencing and the silt control on site. After that, work must not go past an inspection stage until the inspector clears it.

The Township does not publish permit processing times. Its guides say timing depends on the number of applications, how complex the project is, and whether the application is complete.

The City's guide for an addition or alteration to a single-family house (April 12, 2022) lists the permit work that comes up on a large renovation: repairing, renovating or adding to a house, removing, moving or building interior walls, finishing an unfinished area, building or removing a secondary suite, enclosing a porch or deck, turning a carport into a garage or living space, and installing new plumbing fixtures. It lists window replacement, re-roofing, replacing exterior finishes, new cupboards and painting as work that needs no building permit.

Our bathroom renovation page explains the City's utility review for houses over 30 years old or renovations worth more than $100,000. A whole-home job can pass that dollar figure on its own, and the guide says the applicant asks the Engineering Department for an estimate of any upgrade. The guide also sets site rules: storm drainage connects to the City storm sewer, or to an engineered infiltration gallery where there is no connection, and sanitary or storm lift pumps are not allowed in single-family areas.

South Langley has its own rule. Where a lot there has no City storm sewer, an addition needs an integrated rainwater management plan, unless it adds 25 m² of roof or less. The City's guide places South Langley south of Grade Crescent and 50 Avenue, between 196 Street and 210 Street, and its Design Criteria Manual maps the exact lots.

City inspections follow the stages in its guide: forms, service connection, before backfill, rough plumbing, floor slab, framing, insulation and vapour barrier, and final. Which ones apply depends on the work. Additions must meet the current energy and ventilation rules of the BC Building Code, and every contractor and trade working in the City needs a City business licence.

In the Township, a basement finish needs a building permit, with a scaled floor plan that labels every room and gives the total area being finished. The Township's basement guide says a room with a closet counts as a bedroom, and bedroom windows must meet the emergency exit size. The City's guide gives that size: an opening of at least 0.35 m², with no side shorter than 380 mm. When new bedrooms go into a house on septic, the ROWP signs a referral form and seals the floor plan.

A secondary suite takes its own permit. The Township limits a suite to 120 m² of finished living area, not counting shared laundry and exits, and its zoning allows one suite per house. The suite drawings must show the fire separation between the suite and the main house, the fire-resistance details of walls and floors, photoelectric smoke alarms and carbon monoxide alarms with their interconnection, and the heating and ventilation system. On a lot with a private well, the checklist asks for well water potability reports when a suite is added.

The 2024 BC Building Code also asks for cooling. The Township's bulletin on requirement 9.33.3.1(2) says a suite counts as its own dwelling unit, so it needs at least one living space that the cooling equipment can hold at 26°C or lower. The equipment must be permanently installed, which rules out portable and window air conditioners.

Suites in the Township carry a yearly Secondary Suite Infrastructure Fee of $145 from 2026, billed with property taxes. In the City of Langley, a suite can be up to 100 m² and no more than 40% of the building, and the owner must live on the lot.

The Township's community plan says Brookswood and Aldergrove grew fast in the 1970s, and that Walnut Grove was established as a new urban community in the 1980s. Houses from both decades fall before 1990, the year the Township uses in its renovation guide: a hazardous material survey and a Notice of Project may be required for homes built before then.

WorkSafeBC says asbestos was widely used in BC building materials until the early 1990s, that homeowners need their home tested before a renovation or demolition, and that only qualified professionals can remove it. A licensed abatement contractor does that work before our demolition starts. For moderate or high risk asbestos work, WorkSafeBC must receive a notice at least 48 hours before it begins.

A large renovation brings a second WorkSafeBC rule. Section 20.2 of the Occupational Health and Safety Regulation requires a Notice of Project at least 24 hours before work starts when labour and materials are estimated to cost more than $100,000, or when a professional engineer designed the project. We plan it into the start date.

Older houses on rural and suburban lots add septic and well questions. The Township's community plan says rural areas are served by on-site sewer systems, and the Brookswood-Fernridge plan says many properties in its undeveloped south use private wells. A renovation that adds bedrooms or plumbing fixtures on septic goes to a ROWP first. The Township issues the permit once it has the Fraser Health record of filing, or a referral form when the system needs no work.

Some houses are worth keeping. Others no longer fit the owner's plans, and a new house makes more sense. BC Housing's Regulatory Bulletin 6 (October 2023) says a renovation normally needs no new home registration. But when 25% or less of the original structure above the foundation remains, or 75% or more of the finished home is new, BC Housing treats the project as a new home. A licensed residential builder must then arrange home warranty insurance, or the owner needs a formal exemption such as an Owner Builder Authorization. An addition that creates a legal secondary suite needs no registration. The City of Langley's guide adds that when an addition or alteration exceeds 75% of the original building, the City may ask for that paperwork.

A rebuild follows the new house rules. Since April 1, 2025, every new house in the Township must meet Step 4 of the BC Energy Step Code and EL-3 of the Zero Carbon Step Code, and the Township issues the permit only after it receives the BC Housing warranty form. In the suburban (SR) and residential (R) zones, the old house must be demolished when a new one replaces it. On a rural (RU) lot, the Township may let the owner convert the old house into an accessory building, once the kitchen and bathroom fixtures, 220 volt appliances, furnace and hot water tank are taken out.

Near the rivers, the flood rules may decide which option works. Section 105 of Zoning Bylaw 2500 exempts a renovation with no addition, and an addition of less than 25% of the floor area, from the flood construction level. A new house near the Fraser, in Fort Langley for example, must put its living space at or above that level.

If a rebuild fits better, our page on the custom home builder in Langley covers lots, farmland rules and new house permits. We can price both options from the same site visit.

BC Housing licenses residential builders for new homes: a general contractor who wants to build a new home in BC must first hold that licence. BC Housing's separate licence for building envelope renovations lists buildings with only one or two units among its common exemptions. For a house renovation, these are the checks a homeowner can make:

We have found no named, credible source for Langley renovation prices, so we print none. Each job is priced from a site visit and a written scope of work, and where something behind a wall cannot be seen until it is opened, we set a documented contingency for it at the start. These change the price:
