What can I build on my Whistler lot?
Whistler allows up to four homes on most residential parcels. What almost nobody tells you is that all four share a single floor area cap of 511 square metres, and that the in-ground basement exclusion is worth more than the extra units. This tool runs Section 35 of Bylaw 303 and shows you both.
Run the numbersThe rules are not in the zone pages, which is why most summaries of Whistler get this wrong. The small-scale multi-unit housing regime lives in Part 5, Section 35 of Zoning and Parking Bylaw 303, and it applies "despite any other provision in this Bylaw". Read the RS1 page on its own and it still looks like one house and an auxiliary unit. Anyone parsing the zone tables alone is out by two or three homes on nearly three thousand parcels.
Your parcel, under Section 35
This is what drives the in-ground basement exclusion, which is the single most valuable number on this page. Same units as the parcel area above. Set it to zero to leave the basement out of the calculation.
Four homes, one envelope
Section 35 lets a parcel over 280 square metres hold four homes. Clauses 35(8) to 35(10) then cap the gross floor area for the whole parcel at a floor space ratio of 0.40, or 511 square metres, whichever is lower, and in RT1 and RT6 at 0.45 or 511. The cap does not rise with the unit count.
| Parcel | Homes | Whole-parcel floor area | Average per home |
|---|---|---|---|
| 250 m² RS1 | 3 | 100 m² | 33 m² (359 sq ft) |
| 700 m² RS1 | 4 | 280 m² | 70 m² (753 sq ft) |
| 900 m² RT1 | 4 | 405 m² | 101 m² (1,090 sq ft) |
| 1,400 m² RS1 | 4 | 511 m², capped | 128 m² (1,375 sq ft) |
There is a hard floor underneath this. Clause 35(11)(c) says no home may be smaller than 32.5 square metres. On a parcel under about 244 square metres in the 0.40 zones, three homes at the minimum size do not fit inside the floor area, so the by-law permits a unit count the envelope cannot hold. The tool flags that when it happens.
The basement is where the space actually is
Section 26(1)(a)(ii) excludes in-ground basement floor area from gross floor area completely, up to 125 per cent of the floor area of the storey immediately above. Not a discount. Excluded.
The test has three limbs, all of which must hold. At least 50 per cent of the exterior wall height must sit below finished grade at each wall, with wall height measured from the finished floor to the underside of the floor system above. It must be the lowest floor of the building. And the exclusion is capped at 125 per cent of the storey immediately above.
On a flat parcel that is difficult. On a sloped Whistler parcel it is often achievable on three walls and marginal on the fourth, and the difference between three walls and four is worth hundreds of square metres. This is the part of a Whistler project where design work pays for itself, and it is why two houses of the same permitted floor area can end up very different sizes.
Crawl spaces, void spaces, parking areas, elevators and fixed machinery are excluded separately under other limbs of Section 26(1)(a) and are not counted inside the 125 per cent. They may sit on the same level as the in-ground basement or above it, but not below it. Under Section 35 the parking exclusion is capped at 87.5 square metres for three homes and 105 for four.
The five gates, and the one that catches people
Section 35(5) applies only if all five of these are true. Fail any one and you are back to the base zone.
- The parcel is not in a transit-oriented area. No Whistler parcel currently is, because transit frequency does not meet the provincial standard, so this one passes everywhere.
- It is serviced by municipal water and sewer.
- It is wholly or partly inside the Whistler Urban Development Containment Area, the boundary in Schedule A to the Official Community Plan.
- It is 4,050 square metres or less.
- Its zone has a minimum subdivision area under 4,050 square metres.
A bigger parcel gets fewer homes
Gate four is a ceiling, not a floor. At 4,050 square metres you may have four homes. At 4,051 you may have one, plus an auxiliary unit. That is the opposite of how every other municipality on this list works, and it is the single most surprising line in the Whistler by-law.
RS-E1 is out, whatever its size
Gate five looks at the zone rather than the parcel. RS-E1 has a minimum subdivision area of 40 hectares, far above 4,050 square metres, so no RS-E1 parcel qualifies no matter how modest it is. A 900 square metre RS-E1 lot gets the base zone answer.
The containment boundary is not published
Gate three is decisive and we cannot check it for you. The Whistler Urban Development Containment Area is defined in Schedule A to the Official Community Plan and illustrated in Figure 5-H, but it is not available as a dataset anywhere we could find. The tool asks you rather than guessing.
RI1 owners get a choice nobody else has
Clause 35(26) lets an RI1 parcel be developed entirely under the RI1 zone rules, or entirely under Section 35. Not a mixture. RI1 is also the only zone permitting two auxiliary residential dwelling units, on parcels over 695 square metres. Both routes are worth modelling before you commit.
For scale, the Municipality's own figures: 93 parcels allow up to three dwelling units and 2,942 allow up to four. That is the whole addressable set, a little over three thousand parcels.
Can any of it be nightly rented?
This is the question most Whistler owners are actually asking, and the honest answer is that Section 35 does nothing for it. Clause 35(23) is explicit: the Section "shall not be interpreted or applied to increase the number of dwelling units on any parcel of land that may be used as tourist accommodation, over the number that would otherwise be permitted".
Four separate things have to line up.
| 1. Zoning | Your zone must list tourist accommodation or temporary accommodation as a permitted use. Most residential zones do not. An auxiliary residential dwelling unit never qualifies, in any zone, including RTA1 where the text says it "shall not be used for the temporary accommodation of paying guests". |
|---|---|
| 2. Your title | A Phase 1 or Phase 2 covenant can control how you use the property regardless of zoning. Phase 2 typically caps the owner at 28 days per winter season and 28 per summer, with the property in a rental pool the rest of the year. |
| 3. Business licence | An RMOW tourist accommodation business licence, required since 2017 and independent of the provincial rules. |
| 4. Provincial registration | Registration with the BC short-term rental registry, required since 1 May 2025. Platforms validate listings against the number. |
The BC principal residence requirement does not apply in Whistler. In the Municipality's own words, "the requirement that limits short-term rentals to the host's principal residents and one secondary suite or accessory dwelling unit on the same property does not apply to Whistler". Whistler regulates by zoning, covenants and enforcement instead. Almost every generic article about BC short-term rental rules is misleading if you read it about a Whistler property.
On the licence fee: RMOW's fee schedule lists Tourist Accommodation Business at a flat $250.00, while the tourist accommodation page renders it as $250 per guest unit. The Hotel and Campground rows do carry explicit per-unit qualifiers and the Tourist Accommodation row does not, so we read it as a flat fee, but confirm with RMOW Licensing before budgeting on it.
One thing we could not resolve
Whistler met the original provincial small-scale housing requirement on time. Bylaw 2440 was adopted on 11 June 2024, and Bylaw 2461 replaced Section 35 with the current text, adopted 11 March 2025. No extension, no exemption, nothing late.
Bill 25 then raised the requirement to between three and six units, with a compliance date of 30 June 2026. The consolidated bylaw dated 7 August 2026 still delivers three or four, and its table of contents still attributes Section 35 to Bylaw 2461, which is how that document records the most recent amendment to a section. One further zoning amendment, Bylaw 2507, was adopted on 14 July 2026, but its contents do not appear against any section heading we could read, and the Municipality's own small-scale housing page has not been updated since 31 October 2025.
So there are three possibilities and we cannot tell them apart from published documents: the Minister granted an extension, Bylaw 2507 made the change without the annotation being updated, or Whistler is out of step. We are not going to guess. If you are planning around unit counts in Whistler this autumn, call RMOW Planning on 604-935-8170 or email planning@whistler.ca and ask what Bylaw 2507 did, and we will do that alongside you.
Part 6 of the bylaw, which sets the base parking rates, could not be retrieved either, so this page shows no base zone parking figures. The Section 35 rate of one space per home to a maximum of six is confirmed from the clause itself and from the Municipality's own FAQ.
What it costs to build in Whistler
Eurohouse builds new multi-unit work at $450 to $650 per square foot, subject to access, terrain and finishes. That is construction only. It excludes land, municipal fees, consultants, geotechnical and arborist reports, survey, landscaping and furniture. The number we stand behind is the fixed price after we have walked the site.
Whistler sits toward the upper half of that range more often than the Lower Mainland does, for reasons that are structural rather than negotiable: snow load and the resulting structure, the short building season, trades and materials travelling up the highway, rock, and steep access. A four home project inside a 511 square metre cap is also a lot of envelope and servicing per square foot of sellable area, which is the opposite of the economics that make a large single house efficient.
The basement is where the value hides. Excluded floor area still costs money to build, but it costs considerably less per square foot than above-grade area, and it does not consume any of your 511 square metres.
These are construction ranges for planning purposes, not quotes.
Questions we get asked
How many homes can I build on a Whistler lot?
Three on a parcel of 280 square metres or less, and four above that, provided all five gates in Section 35(5) are met. The Municipality's own count is 93 parcels at three units and 2,942 at four. What the by-law does not do is raise the floor area to match: all of those homes share a single whole-parcel cap.
Why is my Whistler floor area capped at 511 square metres?
Because clauses 35(8) to 35(10) set the maximum for the whole parcel at a floor space ratio of 0.40, or 511 square metres, whichever is lower, in RS1, RS2, RS4, RI1 and RT2, and at 0.45 or 511 in RT1 and RT6. It applies "irrespective of site dimensions", so the usual frontage rules stop mattering once you build three or four homes. On a large parcel the 511 binds and four homes average about 128 square metres each.
Does the in-ground basement really not count?
Correct, up to 125 per cent of the floor area of the storey immediately above, provided at least 50 per cent of the exterior wall height is below finished grade at each wall and it is the lowest floor. Wall height is measured from the finished floor to the underside of the floor system above. On a sloped lot this is frequently the difference between a cramped project and a comfortable one, and it is worth designing around from the first sketch rather than discovering late.
Do I have to rent some of the homes out?
Yes, but more lightly than people expect. On three homes, one must be residential rental tenure; on four, two must be. That means occupied under a tenancy agreement as a principal residence. There is no rent restriction and no price restriction. You designate them on the building permit application, and the Municipality may require a statutory declaration once a year confirming they were rented. If you later strata title the parcel, an employee housing agreement with the Municipality is required on at least those units.
My lot is over an acre. Do I get more homes?
No, you get fewer. Clause 35(5)(d) sets a ceiling of 4,050 square metres, so a parcel above that size is excluded from Section 35 entirely and falls back to the base zone, which is generally one detached dwelling and an auxiliary unit. It is the only rule of its kind among the municipalities we work in.
Can I nightly rent the extra units?
No. Clause 35(23) says Section 35 cannot increase the number of units on a parcel that may be used as tourist accommodation. Auxiliary residential dwelling units can never be nightly rented in any zone. Where the zoning does permit tourist accommodation, you still need clear title covenants, an RMOW business licence and provincial registration. The BC principal residence rule does not apply in Whistler.
Which Whistler zones does Section 35 actually reach?
Those that limit residential development to a detached dwelling, a detached dwelling with one or two auxiliary residential dwelling units, or a duplex. In practice that is RS1, RS2, RS4, RI1, RT1, RT2 and RT6 for the named floor area figures, with other qualifying zones falling back to their base zone maximum under clause 35(7). RS-E1 is excluded by its 40 hectare subdivision minimum.
Does Eurohouse build in Whistler?
Yes. We are a licensed general contractor working in Whistler, Squamish, West Vancouver, North Vancouver and Vancouver, on custom homes, multi-unit and infill work, European kitchens and windows, and insurance restoration. Call 604-728-5682 or email info@eurohouse.ca.

Send us the address and we will model the basement first
On a Whistler parcel the in-ground basement exclusion usually decides whether the project works. We will check the containment boundary, confirm the zone and servicing, and model what the slope actually gives you before anyone draws a plan. No charge for the first conversation.
