Home Renovations in Langley, BC
Langley is two municipalities — the Township of Langley and the City of Langley — with separate building departments, tree bylaws and construction hours. Kyrax Developments renovates homes in both as a licensed general contractor, and the first thing we confirm on any Langley job is which one the address is in.
A whole-home renovation, permit to final.
Additions
New floor area on a house under the right municipality’s building permit, with the site plan, soil and erosion forms and, on septic, the Fraser Health filing the Township asks for.
Interiors & basements
Kitchens, bathrooms, moved walls and finished basements. Both Langleys need a building permit to renovate or finish a basement; the City lists moving interior walls by name.
Decks & porches
Decks, porches and sundecks, and carport conversions, which the City of Langley lists among the work that needs a permit.
Retaining walls
Walls that need a permit over 1.2 metres in the Township and over 1 metre in the City, engineered where required.
Trees
A tree check before design: the Township protects trees from 20 centimetres, and reviews tree protection before it issues a building permit.
Older homes
A hazardous material survey where the Township may ask for one, and in the City, Engineering’s call on utility upgrades for older houses and larger renovations.
Two Langleys, two rulebooks.
The Township and the City write their permit lists, tree rules and hours differently, and some of the differences are small enough to miss: a retaining wall a few centimetres over a metre, or a Saturday that ends at 5 p.m.

From jurisdiction to final inspection.
Jurisdiction & lot check
Township or City first, then the lot: protected trees, septic, watercourses and easements, and the age of the house and its services.
Drawings & application
The municipality’s own list: a title search no older than 30 days in the Township and 48 hours in the City, and the forms each one asks for.
Review & permits
Plan review, the Township’s tree review where the bylaw applies, then the building permit; gas and electrical permits from Technical Safety BC.
Construction
Work inside each municipality’s hours: to 8 p.m. on Saturdays in the Township, to 5 p.m. in the City, and never on a Sunday or statutory holiday in either.
Inspections & final
Building inspections with the municipality that issued the permit, and Technical Safety BC’s gas and electrical inspections.
What's different about renovating in Langley.
In the Township, a building permit affected by the Tree Protection Bylaw has to be reviewed and accepted for tree protection before it can issue, and drawings that ignore the bylaw can be rejected or delayed. The City adopted a new tree bylaw in January 2026.
Both Langleys bar construction on Sundays and statutory holidays. On Saturdays the Township allows it until 8 p.m. and the City until 5 p.m.; on weekdays the Township’s day ends at 8 p.m. and the City’s at 7.
Many Township properties are on septic. There, the Township wants a registered onsite wastewater practitioner’s Fraser Health filing, or a referral form, before an addition’s building permit can issue.
In the City, a house over 30 years old or a renovation valued over $100,000 goes to the Engineering Department, which decides whether the existing utilities need upgrading.
No two renovations price the same.
We don't publish a flat price for a Langley renovation, because scope varies too much from one home to the next for a single number to be honest. These are the factors that move the estimate.
Township or City
Each has its own permit list, forms and fees, and a project that is permit-free in one can need a permit in the other.
Engineering
Moving load-bearing walls or adding floor area brings sealed structural drawings and a Schedule B from a registered professional.
Walls & septic
A retaining wall over the municipality’s height limit, or a septic system on the lot, adds professionals and paperwork to the permit.
Tree permits
Protected trees on the lot bring tree permits, arborist reports where required, and in the Township a tree review before the building permit.
Utility upgrades
In the City, an older house or a larger renovation can mean Engineering requires utility upgrades, estimated on request.
Survey & abatement
If the survey finds asbestos in the materials being disturbed, licensed abatement comes before demolition — a separate contractor and a separate line item.
Answers before you ask.
Usually, in either Langley, but the two lists differ. The Township of Langley's guide requires a building permit to alter, repair, renovate, relocate or add to a building, finish a basement or build a suite, build retaining walls over 1.2 metres, and install new plumbing fixtures or re-arrange piping. The City of Langley's guide adds moving or building interior walls, enclosing a porch or sundeck, converting a carport and retaining walls over 1 metre, and says no permit is needed for non-structural work such as replacing cupboards, painting or re-roofing.

Only with a permit if it is protected, and most mature trees are. The Township's Tree Protection Bylaw protects any tree with a trunk diameter of 20 centimetres or more at breast height, along with replacement trees and trees used by nesting raptors, osprey, pileated woodpeckers, herons or hummingbirds. Removal in conjunction with a building permit application is one of the situations the Township allows; cutting is not permitted between 6 p.m. and 8 a.m.; and a building permit affected by the bylaw has to be reviewed and accepted for tree protection before it can issue. Sources: Township of Langley, Tree Protection Bylaw 2019 No. 5478, Tree Protection and Building Permits, verified September 2026.
Under the City's Tree Protection and Management Bylaw, which it adopted in January 2026: significant trees of 75 centimetres in diameter or more at breast height, trees in environmentally sensitive areas, replacement trees, trees that must stay through redevelopment and trees over 20 centimetres on lots with active development applications, and City trees. Unauthorized removal of a protected tree can bring fines starting at $3,000 per tree. The City's page sets out when a hazardous tree can come down without a permit.

It depends which Langley. The Township's Community Standards Bylaw allows construction sound from 7 a.m. to 8 p.m. Monday to Saturday and bars it on Sundays and statutory holidays; its bulletin counts warming up equipment when trades arrive or leave as construction activity. The City's Noise Bylaw allows construction from 7 a.m. to 7 p.m. Monday to Friday and 7 a.m. to 5 p.m. on Saturdays, with no construction noise on Sundays or statutory holidays. Sources: Township of Langley, Community Standards Bylaw 2019 No. 5448, sections 10.3 and 10.4, and Construction Sound bulletin; City of Langley, Noise Bylaw No. 2628, sections 2.1 and 2.2, verified September 2026.
In the Township, when it is over 1.2 metres high; in the City, when it is over 1 metre. Both municipalities list retaining walls among the work that needs a building permit, and an engineer's sealed design is typically part of it.

A building permit application and checklist, a title search or freehold transfer no older than 30 days, a site plan disclosing rights-of-way, watercourses and easements, sealed structural drawings and a Schedule B where they apply, a soil declaration, and an erosion and sediment control form. On a property served by a septic system, a registered onsite wastewater practitioner's Fraser Health record of filing, or a building permit referral form, has to be in before the permit issues. For a home built before 1990, a hazardous material survey and a WorkSafeBC notice of project may be required.

It can. The City's addition and alteration guide says that where a house is more than 30 years old, or the renovation's construction value is greater than $100,000, the Engineering Department will determine whether the existing utilities need to be upgraded, and the applicant should ask Engineering for an estimate. The same guide asks for a title search no older than 48 hours with the application. Source: City of Langley, Addition or Alteration guide (April 2022), verified September 2026.
On our projects, a bathroom renovation runs 4 to 8 weeks and a basement finished as a recreation room 6 to 10 weeks, measured from demolition. That is our own clock, and it doesn't include the permit: neither municipality's permit pages we read publish a processing time, and in the Township a permit affected by the Tree Protection Bylaw can't issue until the tree review is accepted. Sources: Township of Langley, Building Permits and Residential Building Permits; City of Langley, Addition or Alteration guide, verified September 2026.
In the City of Langley, yes: its guide lists constructing, covering or enclosing a porch or sundeck, and converting a carport to a garage or living space, among the work that needs a building permit. The Township's guide requires a permit to construct a new structure or add to an existing building, which covers a deck attached to the house.

WorkSafeBC's guidance is yes. It tells homeowners to get their home tested for asbestos before starting a renovation or demolition project, noting that many older homes contain some form of it, and says any asbestos found must be properly removed or contained before the project can begin; if only some areas will be renovated, only those need to be surveyed. The Township of Langley notes that a hazardous material survey and notice of project may be required for homes built before 1990, and since January 1, 2024 abatement contractors must be licensed in BC.

Yes. Kyrax Developments Ltd. holds BC Housing Residential Builder Licence #57802, in good standing, as a General Contractor and Developer. On a Langley renovation that means a single contract for the whole job: we pull the permits, coordinate the trades and book the inspections, and permitted work is inspected the same as any other licensed scope of work. Verify the licence on the BC Housing Licence Registry.
Yes. Kitchen renovations in Langley and bathroom renovations in Langley cover those rooms in both municipalities, and basement suites in Langley covers each one's suite rules.
