Important legal and code disclaimer — information reviewed July 18, 2026
This page is provided by MarsLED solely for general educational and product-selection information. It summarizes publicly available Saskatchewan code, government, municipal and manufacturer information reviewed as of July 18, 2026. It is not legal advice, engineering advice, architectural advice, fire-protection design advice, electrical advice, a code interpretation, an inspection, an approval, or a representation that any product or installation complies with every requirement applicable to a particular property, occupancy, permit, tenancy or project.
Building, fire, electrical, rental and accessibility requirements may be amended, replaced, interpreted differently or supplemented by local bylaws, permit conditions, inspection orders or project-specific requirements. Before purchasing, specifying, replacing or installing an alarm, the customer, owner, landlord, contractor and design professional must independently verify current requirements with the applicable local authority, fire department, electrical authority, permit issuer and any other authority having jurisdiction.
Current Saskatchewan alarm requirements
Saskatchewan’s Building Code Regulations require carbon-monoxide alarms and smoke alarms, or approved combination smoke and CO alarms, in all residential buildings regardless of when the building was constructed. Enforcement of the province-wide requirement began July 1, 2022.
Official sources:
Saskatchewan alarm requirements
2022 province-wide requirement
CO alarms
Working carbon-monoxide alarms are also required. A listed combination alarm may provide smoke and CO detection where its location and configuration satisfy the applicable requirements.
Owner responsibility
Building owners are responsible for installing and maintaining required alarms and replacing them at the end of their manufacturer-specified service life.
Do not assume one alarm covers the entire building.
The required number and location of alarms depend on the building layout, sleeping areas,
fuel-burning equipment, suites, common spaces and local requirements.
Henry’s Law and the November 1, 2026 change
Saskatchewan announced Henry’s Law on May 5, 2026. The enhanced rule is scheduled to require carbon-monoxide alarms in every residential suite in multi-unit residential buildings by November 1, 2026, regardless of the suite’s location, building age or last renovation date.
Official source:
Saskatchewan introduces Henry’s Law
Multi-unit residential buildings
The announced change covers apartments, condominiums, houses with secondary suites and other buildings containing multiple residential suites.
Every residential suite
The new rule is intended to require a CO alarm in each residential suite regardless of where that suite is located within the building.
Effective-date caution
As of this page’s July 18, 2026 review date, the announced implementation date is November 1, 2026. Confirm the final regulation and effective date before relying on it.
Current rules still apply before November 1, 2026.
Henry’s Law strengthens the existing Saskatchewan framework; it does not eliminate current
owner obligations for working smoke and CO alarms.
Alarm types permitted for different buildings
Saskatchewan identifies several alarm formats that may be suitable depending on the circumstances and building layout. Product type alone does not determine compliance; placement, listing, backup power and manufacturer instructions also matter.
Official source:
Saskatchewan alarm types and installation
Hardwired alarms
Hardwired alarms may detect smoke, CO or both. Fixed wiring and interconnection must follow applicable electrical, code and manufacturer requirements.
Ten-year battery alarms
Tamper-resistant alarms with a 10-year battery may be accepted in applicable locations and building conditions.
Plug-in CO alarms
Plug-in CO alarms with battery backup may be suitable for applicable locations, subject to the installation requirements and manufacturer instructions.
Local requirements can be more specific.
Additional alarms or different power arrangements may be required by the Building Code
Regulations, the building’s layout or a community bylaw.
Location, installation and maintenance
Saskatchewan requires alarms to be installed, tested and replaced according to the manufacturer’s instructions. Additional locations can be required based on the building layout, existing alarm system and the location and type of fuel-burning appliances.
| Installation factor | What to verify | Why it matters |
|---|---|---|
| Sleeping areas | Required alarm locations in relation to bedrooms and sleeping rooms | Occupants must receive effective warning while asleep. |
| Building layout | Storeys, suites, corridors, common areas and shared walls or floors | Larger or multi-unit buildings can require multiple alarms. |
| Fuel-burning equipment | Furnaces, boilers, fireplaces, stoves, dryers and water heaters | Equipment type and location can affect required CO-alarm placement. |
| Existing alarm network | Power source, wiring connector, mounting plate and interconnection | A replacement must be compatible with the existing approved system. |
| Service life | Manufacture date, expiry marking and replacement instructions | Smoke, CO and combination alarms must be replaced at end of life. |
Replace alarms when their age is unknown.
Saskatchewan advises replacing an alarm when the owner cannot determine how old it is.
Rental properties and municipal requirements
Saskatchewan’s province-wide smoke and CO requirements apply to residential buildings, including rental housing. Municipal fire bylaws may add testing, recordkeeping, hardwiring, permit and installation requirements.
Municipal example:
City of Regina rental-property rules
Province-wide owner duty
Building owners are responsible for installing and maintaining required smoke and CO alarms in Saskatchewan residential buildings.
Regina rental properties
Regina’s Fire Bylaw requires hardwired smoke alarms in rental properties, six-month testing, testing before a new tenancy and written testing records.
Electrical installation
Regina requires hardwired rental-property smoke alarms to be installed by a licensed journeyperson electrician with an electrical permit in place.
Do not apply Regina’s bylaw province-wide.
Rental owners outside Regina must confirm the applicable municipal bylaw, permit and fire-authority requirements.
Existing homes, renovations and new construction
Saskatchewan’s province-wide alarm requirement applies regardless of building age, but new construction, renovations, secondary suites and multi-unit projects may trigger additional Building Code, electrical and interconnection requirements.
| Project context | Planning approach | What to verify |
|---|---|---|
| Existing house | Confirm current smoke and CO coverage and alarm age | Required locations, approved alarm type and manufacturer instructions |
| Rental property | Review province-wide owner duties and municipal bylaws | Testing, records, hardwiring, permits and tenant-change requirements |
| Renovation or addition | Review the permit scope and current Building Code provisions | Hardwiring, backup power, interconnection and room locations |
| Secondary suite | Coordinate alarms across suites and common spaces | Smoke and CO interconnection, separation design and Henry’s Law timing |
| Multi-unit residential building | Review current suite coverage and prepare for the November 1, 2026 change | Every residential suite, shared spaces, owner responsibility and final regulation |
| New construction | Follow approved plans and the current Saskatchewan-adopted code | Complete alarm layout, power, backup, interconnection and commissioning |
Visual signalling and LED strobe alarms
Audible alarms may not provide effective notification for every occupant. Where an approved design, accessibility requirement or occupant need calls for visual warning, use a listed visual-signalling device or integrated strobe alarm suitable for the application.
Manufacturer sources:
Kidde smoke/CO strobe alarm
Kidde smoke strobe alarm
177-candela visual warning
The Kidde P4010ACLEDSCA and P4010ACLEDSCOCA product families use an integrated 177-candela LED strobe designed for visual notification.
Smoke-only versus smoke + CO
P4010ACLEDSCA detects smoke only. P4010ACLEDSCOCA-2 adds independent carbon-monoxide detection.
Strobe requires AC power
The integrated strobe requires normal AC power. Backup power supports the alarm functions identified by the manufacturer, not necessarily the visual strobe during an outage.
A product feature is not a compliance guarantee.
Candela rating, sensing functions, placement, power, interconnection and any synchronization
requirements must match the approved project design.

Replacing a Kidde P1275CA smoke alarm
Customers searching for P1275CA are commonly replacing an existing alarm rather than planning a new alarm system. Replacement selection must consider the entire interconnected network, not only the physical appearance of the old alarm.

Kidde 20SAR-CA specifications
Evaluate a current replacement
Current Kidde hardwired smoke alarms such as 20SAR-CA may be replacement options to evaluate, subject to full compatibility and project review.
An adaptor may be required
A newer alarm may require an approved Kidde wiring adaptor or new mounting plate. Never force or modify a connector simply to make a replacement fit.
Verify the entire system
Confirm voltage, wiring connector, mounting plate, sensing functions and compatibility with every interconnected alarm before ordering.
Do not treat a suggested model as an automatic drop-in replacement.
Final compatibility must be confirmed through Kidde Canada, product documentation and a
qualified installer familiar with the existing alarm network.
