Martindale, Calgary: where Northeast owners build additions

Additions are rare in Calgary's Northeast, and Martindale has more of them than anywhere else in the sector. City of Calgary open data shows 18 addition permits issued here from January 2023 to 29 September 2026, ahead of Saddle Ridge's 16, in a community where 2021 households averaged 3.7 people. Owners also filed 135 development permit applications for suites, the fifth most in Calgary.

Why do Martindale owners build additions?

The permits don't give reasons, but the households do. The 2021 census counted 14,540 people in 3,945 households, averaging 3.7 people, tied with Coral Springs for fourth highest in Calgary. Only 10% of households were one person.

Population and household figures are from the 2021 Census of Canada as published by the City of Calgary; dwelling types are from the City's 2019 civic census, the last one it ran. Newer communities have grown since.

The houses are the other half of it. The 2019 civic census counted 3,553 single-detached dwellings among 4,270, about 83%, with no apartments at all and 499 converted structures. With so few apartments or townhouses in the community, the data suggests that when a household here grows, building out is a common answer.

What does an addition look like in Martindale's permits?

Slower than most permits here, and mid-range on paper. Martindale's additions ran 4 in 2023, 3 in 2024 and 7 in 2025, with 4 through 29 September 2026. The median permit took 56 days from application to issue, against 9 days for a detached garage and 13 for a basement.

Permits issued, excluding cancelled ones. "Share of Calgary" is this community's part of the citywide count for the same project type and years. Declared value is what the applicant wrote on the permit application. It is not a quote and runs below real costs. Medians are shown only where a category has at least 5 permits.

The median declared value was $51,067, 25th of 58 communities. That's what the applicant wrote on the permit, and it runs well below what an addition costs. The home addition cost guide has 2026 ranges, and the bedroom size page helps if the addition is a bedroom.

Garages are still the biggest single build here, with 103 permits, and renovations the most common permit overall at 136. Martindale had no new house permits in the window.

How many Martindale homes add a suite?

A lot went through the development permit process. Of 254 applications since 2023, 135 were for suites, and 191 of 195 decided applications were approved, with 4 refused and a median 44 days to a decision.

Development permits applied for from 1 January 2023; many home projects in Calgary need only a building permit, so these are a subset of all work. The registry lists suites the City has confirmed meet the rules, not every suite that exists.

Building permits followed: 36 for altering existing space into a suite and 16 in the City's New work class, suites built as new construction, most likely inside existing homes since no new houses were permitted here. The alteration permits took a median 39 days to issue, slower than 72 of 80 communities with a median. The registry lists 367 Martindale suites, sixteenth in the data, adding 30 to 37 a year.

The 8 backyard suites are new. All were issued from 2025 on, with a median declared value of $129,227. As of October 2026 a lot can hold one suite, not both, and a backyard suite in R-C1N or R-C2 is discretionary. The backyard suites guide and the legal basement suite guide carry the current rules.

What land use covers Martindale?

R-C1N on 49% of the districted area and R-C2 on 23.3%. S-SPR covers 11.6% and S-R 5.4%, and residential districts take 74.2% of Martindale in all.

The share of the community's districted area in each land use district, from the City's district and community boundary maps intersected exactly. Districts change by lot and by amendment: check a specific lot on the City's land use map before you plan.

Development permit applications tell a slightly different story: R-CG was named 120 times, R-C1N 92 times and R-C2 33 times. Check your lot's district on the City's land use map, because an addition's setbacks and height come from it.

Walking a Martindale addition at full size

An addition has to join the house without wrecking what's already there: the hallway it opens from, the room it borrows light from, the stair it sits next to. On the studio's walkable LED floor, the existing floor and the addition are lit together at full size with room names and dimension lines, so you can walk from the old kitchen into the new room and feel where the opening lands. Freestanding walls, a dining table and a sofa can be moved in to test it.

Elevations go up on a wall-size screen behind the floor, changes appear on the floor as they're made, and the session is recorded for you. Send the plans as a PDF or DWG at least three days ahead. The quote is free and based on the plan's size: see pricing, book a session, or go back to the communities hub.
