What zoning means in Calgary
Zoning decides what can be built on a piece of land and how it is used. In Calgary, zones are officially called land use districts, and each property has a land use designation. The two terms mean the same thing. The rules for every district are written in the City's Land Use Bylaw 1P2007.
Your district sets the kind of building allowed, such as a single detached house, a duplex or rowhouses, along with height limits, how much of the lot can be covered, setbacks from the property lines and whether a secondary suite or backyard suite is allowed. It does not set building safety rules. Those come from the Alberta building code and are checked through a building permit.
How to find your zone
- Search your address on the City of Calgary's land use district map, which shows the district for every property in the city.
- Your district code appears on the map along with a link to its rules in the Land Use Bylaw.
- If the code starts with DC, your property has a custom Direct Control district, explained below, and you need to read its own bylaw.
- Zones change over time, so check before you design anything, not just when you bought the house.
- The City's Planning Services Centre can answer questions about a specific property.
How to read a zoning code
Calgary codes follow a pattern. The first letter tells you the family. R is low density residential, H is housing, M is multi-residential, C is commercial, I is industrial, S is special purpose, CC is the Centre City and DC is Direct Control. A C after the R, as in R-C1, means contextual, which is used in established neighbourhoods so new homes fit the street around them.
Some codes carry extra letters or numbers on the map. In mixed use and commercial districts, the number after f is the maximum floor area ratio, the number after h is the maximum height in metres and the number after d is the maximum density in units per hectare. A small s at the end, as in R-C1s, comes from older rules that marked properties where a secondary suite was allowed.

The 2024 rezoning and its repeal
In 2024 Calgary rezoned most low density residential land to R-CG. Council voted to repeal that citywide rezoning, and the change took effect on August 4, 2026, which restored districts such as R-C1, R-C1L, R-C1N, R-C2, R-1, R-1N, R-2 and R-CGex for many properties. In October 2026 the province directed the City to keep the restored rules in place until its review of the Land Use Bylaw, expected in 2027. Our guide to the rezoning repeal explains what changed for additions and suites.
What your zone means for a renovation
- Most interior renovations do not depend on zoning at all. They need building and trade permits, not a change of zone.
- Additions, second storeys, garages and decks are limited by your district's height, lot coverage and setback rules. If a design does not fit, the City may approve a relaxation through a development permit.
- Whether you can add a secondary suite or a backyard suite depends on your district. Our guides to legal basement suites and backyard suites explain the rest.
- Building a duplex, rowhouses or more units usually needs the right district, or a land use redesignation, which is the formal name for rezoning and is decided by City Council after a public hearing.
- Our guide to building and development permits in Alberta explains the permits that go with each kind of project.
Outside Calgary
Every municipality in Alberta has its own land use bylaw and its own codes. Airdrie, Chestermere, Cochrane, Okotoks and Rocky View County all use different district names and rules, so check the bylaw for the municipality your property is in.
