What a Coquitlam Multiplex Costs in City Charges Before You Lay a Brick
Before a single shovel goes in the ground, Coquitlam collects two charges on every new home. On a fourplex they add up to more than a quarter of a million dollars. Budget for those first, then work out what construction costs per square foot.
The two charges, and what they pay for
Development cost charges pay for roads, water, sewer, drainage, parkland and, since recent provincial changes, fire protection and police facilities. Coquitlam's current rates come from Bylaw 5411, 2025, effective June 23, 2025:
| Type | Rate per dwelling unit |
|---|---|
| Single family | $64,396 |
| Duplex, triplex, fourplex or multiplex | $43,483 |
| Townhouse | $38,537 |
| Apartment | $24,435 |
Amenity cost charges pay for community centres, recreation facilities, libraries and public spaces. Coquitlam's Council adopted the programme on July 7, 2025. The city groups single-detached homes, duplexes, triplexes, fourplexes, multiplexes and townhomes together as low-rise residential and charges $21,205 per dwelling unit. Buildings for business, industry and institutions are charged nothing.
These charges replaced most of what the city used to collect through its density bonus and community amenity contribution programs, which were negotiated case by case. The new system is a fixed published rate.
What it adds up to
On a fourplex, using the published rates:
- Development cost charges: 4 × $43,483 = $173,932
- Amenity cost charges: 4 × $21,205 = $84,820
- City charges total: $258,752
That is $64,688 per home before land, design, permits or construction. And that figure covers only the City of Coquitlam. The city also collects money on behalf of the Greater Vancouver Sewerage and Drainage District, the Greater Vancouver Water District, TransLink and school site acquisition. Those rates change, so ask Development Planning to confirm what applies to your project rather than working from a number you read somewhere.
The distinction that changes the maths
Coquitlam's development cost charge guidelines define "single-detached residential use" as including a dwelling unit in a building that contains one dwelling unit and no other principal uses, and which may include a secondary suite, carriage house or garden cottage.
A fourplex, by contrast, is four principal dwelling units.
So the way you arrange three homes on a lot can change how the city classifies the project. That is a question for the city and your designer at the pre-application stage, before you commit to a layout. Ask it early and in writing.
Paying it, and the deposits on top
Both charges are due before the building permit is issued, and development cost charges are also collected when a subdivision is approved. If the total city development cost charge reaches $50,000 or more, you can pay in instalments: 25% up front, with the remaining 75% due within four years of the building permit or on final occupancy, whichever comes first. You provide a letter of credit or surety bond for the balance.
Then there are refundable securities:
- Development permit security: 2.5% of the estimated cost of construction
- Frontage works security: 110% of your engineer's estimate, if you join the Frontage Works Program
- Engineering and public works damage deposit
Frontage works are the upgrades to the street in front of your property: curbs, gutters, sidewalks, lighting, landscaping and lane improvements. Every new development contributes to them, either by paying into the programme or by building them.
The reports you will pay for before you apply
Coquitlam's small-scale housing page lists the professionals a triplex or fourplex usually needs. A BC land surveyor for a topographic plan current within one year. A designer or architect. A civil engineer for the water, sewer and storm connections. A structural engineer. Add an arborist report if there are trees on or next to the property, a geotechnical report if there is a slope, a qualified environmental professional if a creek is nearby, and a heritage professional if the property is on the city's heritage inventory.
Because triplex and fourplex applications count as complex under the city's Building Bylaw, a Coordinating Registered Professional, either an architect or an engineer, must coordinate everyone and sign the building code schedules.
One thing that can stop a project
Fire flow is the volume of water available at enough pressure for firefighters. Coquitlam says redevelopment can proceed without restriction where the supply is 150 litres per second or more. Where it is lower, you can still build, but you pay to upgrade the water system on or near the property first. Check the city's available fire flow map before you buy a lot for redevelopment.
What this comes down to
- Coquitlam charges $43,483 per unit in development cost charges on a multiplex and $21,205 per unit in amenity cost charges.
- A fourplex therefore carries $258,752 in city charges, before regional, TransLink and school charges.
- A single-family home is charged $64,396 in development cost charges, and the city's guidelines treat a house with a secondary suite, carriage house or garden cottage as single-detached residential use.
- Securities add 2.5% of construction cost and 110% of the frontage works estimate, both refundable.

Frequently asked questions
How much are development cost charges in Coquitlam?
Under Bylaw 5411, 2025, effective June 23, 2025, Coquitlam charges $64,396 per single family dwelling unit, $43,483 per unit for a duplex, triplex, fourplex or multiplex, $38,537 per townhouse unit and $24,435 per apartment unit. Commercial space is charged $131 per square metre of gross floor area, industrial $73 and institutional $132.
What is an amenity cost charge and how much is it in Coquitlam?
An amenity cost charge helps pay for community centres, recreation facilities, libraries and public spaces as the city grows. Coquitlam adopted its programme on July 7, 2025. Low-rise residential, which the city defines to include single-detached homes, duplexes, triplexes, fourplexes, multiplexes and townhomes, is charged $21,205 per dwelling unit. Business and industrial buildings are charged nothing.
What do city charges add up to on a Coquitlam fourplex?
Using the published rates, four units at $43,483 in development cost charges is $173,932, and four units at $21,205 in amenity cost charges is $84,820. That is $258,752 in city charges alone. Charges collected for other agencies, such as the regional water and sewer districts, TransLink and school site acquisition, are on top of that.
Is a house with a suite and a carriage house charged the same as a fourplex?
No, and the gap is large. Coquitlam's development cost charge guidelines define single-detached residential use to include a dwelling unit in a building with one dwelling unit that may also contain a secondary suite, carriage house or garden cottage. A fourplex has four principal units and is charged per unit. Confirm your own project's classification with the city before budgeting.
When do I have to pay Coquitlam's development and amenity charges?
Both are due before the building permit is issued, and development cost charges are also collected when a subdivision is approved. If the total city development cost charge is $50,000 or more, you can pay in instalments: 25 per cent up front, with the remaining 75 per cent due within four years or on final occupancy, whichever comes first.
Are there other agencies' charges beyond the City of Coquitlam's?
Yes. The city collects charges on behalf of the Greater Vancouver Sewerage and Drainage District, since Coquitlam sits in the Fraser Sewerage Area, the Greater Vancouver Water District, TransLink, and school site acquisition. Those rates change over time, so ask Development Planning to confirm the amounts in effect for your project.
What deposits does Coquitlam hold during construction?
Coquitlam takes refundable securities. A development permit security is set at 2.5 per cent of the estimated cost of construction. A frontage works security, if you join the Frontage Works Program, is set at 110 per cent of your engineer's estimate. There is also an engineering and public works damage deposit. These come back once staff are satisfied the work is done and has held up.
Which professionals do I have to hire for a Coquitlam multiplex?
Expect a BC land surveyor for the topographic plan, a building designer or architect, a civil engineer for water, sewer and storm connections, and a structural engineer. You may also need an arborist, a geotechnical engineer, a qualified environmental professional and a heritage professional. At building permit stage a Coordinating Registered Professional must oversee the group.
What is a fire flow requirement and can it stop my project?
Fire flow is the amount of water available at the right pressure for firefighters. Coquitlam says areas with a supply of 150 litres per second or more can redevelop without restriction. Where supply is lower, the project can still go ahead but the builder must upgrade the water system on or near the property to reach the safety standard, which costs money.
Can I use the city's free triplex and fourplex designs to save money?
Coquitlam publishes standard plan packages for triplexes and fourplexes that your designer adjusts to your lot's shape and slope, which speeds up staff review. The trade-off is strict: the city requires the interior layout to stay substantially the same, and the exterior appearance and materials cannot change. Alter either and the application returns to the normal design review process.
