Home Renovations in Surrey, BC

The City of Surrey issues a different permit for each kind of renovation work on a single family or detached house. An interior renovation needs an Interior Renovation Permit. Finishing a basement needs its own Basement Finishing Permit. Building out or up needs an Addition Permit.

Every one of them starts with the Building Permit Application Form, a current title search and, when the applicant is not the owner, an Owner Authorization Form. Applications go in by email or in person at City Hall, 13450 104 Avenue. The City's interior renovation page says most interior renovations involve some structural work, and that a Registered Professional may need to provide signed and sealed drawings when a structural part changes. If a window or door is enlarged or added, the plans need an elevation of that wall and a cross-section through it.

The fee is a flat fee based on the proposed cost of the work. The City collects part of it during review and the balance before it issues the permit. Once the permit is issued, the approved drawing set must stay on site for the whole job.

On October 26, 2026, the City's permitting timelines page showed 2.4 weeks for residential addition and renovation building permits, against a City target of 6 weeks. The City calculates the current figure as an average of the permits it processed over the last 30 days. It applies to complete applications, so a missing document or drawing adds time that the figure does not show.

We check each package against the City's list before it goes in, and we ask the designer and engineer for anything that is missing first.

The City of Surrey allows coach houses and garden suites in the residential zones that allow detached houses, duplexes and houseplexes. A unit must be between 35 m² and 75 m². In the RA, R2, R2-O and R3 zones it can reach 120 m² when the existing house is below the maximum floor area ratio, the limit on floor area compared with lot size. A coach house must be attached to a garage, and garage space inside it counts toward that ratio.

On smaller R3, R4, R5, R5-S and R6 lots a coach house needs lane access. Without a lane, a garden suite may be possible instead. Each unit needs one parking space beyond what the house and any secondary suite already require. The City asks for an arborist report when the property has more than 5 trees, a pre-construction BC Step Code compliance checklist, and signed and sealed Schedule B forms from each Registered Professional. Our Langley coach house page shows how we plan these units in the Township and City of Langley.

A general contractor who wants to build a new home in BC must hold a BC Housing builder licence. For a renovation of an existing house, these are checks any homeowner can make:

We have found no named, credible source for Surrey renovation prices, so we print none. Each job is priced from a site visit and a written scope of work. 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:

Parisian Elements, in the photos below, is a whole-home renovation we finished in Rosemary Heights, Surrey. It covered the main floor and the basement. We did it in two phases so the owners could keep living in the house. We take bathroom-only jobs in Surrey too.
