Muskoka Lakes STR Bylaw Is Live: What Cottage Owners Must Do Now
If you own a cottage in the Township of Muskoka Lakes and you've been renting it out on Airbnb, VRBO, or through a local property manager, the rules of the game have officially changed. The Township's Short-Term Rental (STR) licensing bylaw (By-law 2025-049) is on the books — and while the Township permitted operators to advertise and operate without a licence through 2025 due to technical implementation issues, that grace period is ending. Licence applications were required to be submitted by December 31, 2025, and full enforcement of rental restrictions takes effect May 1, 2026. After that date, operating without a licence carries real teeth — fines, licence revocations, and the potential to shut down your rental operation entirely.
At BrambleRidge Home Design Group, we've been fielding calls from cottage owners across the region trying to figure out what this means for their properties. Here's what you need to know right now.

Understanding What the Bylaw Actually Requires
The Muskoka Lakes STR bylaw requires property owners to obtain a municipal licence before advertising or operating any short-term rental — defined as any accommodation rented for 28 consecutive days or fewer. The licensing process isn't just paperwork. It requires a floor plan, site map, proof of adequate insurance, and occupancy information — and the Township reserves the right to inspect properties, and may require confirmation that your cottage meets applicable safety standards before a licence is issued.
That last point is where many owners are getting caught off guard. A cottage that's been in the family for decades — lovingly maintained but never formally upgraded — may not meet current Ontario Building Code requirements for things like egress windows, smoke and carbon monoxide detector placement, electrical panel capacity, or septic system compliance. If an inspector identifies deficiencies, you'll need to address them before a licence is issued.

The Safety Upgrades That Come Up Most Often
In our experience working with Northern Ontario cottage properties, the most common compliance gaps we see involve:
- Egress windows in sleeping areas — Ontario Building Code requires at least one compliant egress opening — a window or exterior door meeting minimum dimensions — on each floor level that contains a sleeping area. Many older cottages have small, fixed, or casement windows that don't meet the standard, and if there's no qualifying exterior door on that level, the deficiency needs to be addressed.
- Smoke and CO detector placement — Detectors must be installed on every level and outside every sleeping area. Battery-operated, plug-in, and hardwired units may all comply with Ontario's Fire Code; however, if you replace a hardwired unit, it must be replaced with another hardwired unit. As of January 1, 2026, hardwired and plug-in CO alarms must include battery backup.
- Septic capacity — This is a big one in cottage country. If your STR licence application increases the declared occupancy of your property, your existing septic system may need to be assessed for adequacy by a licensed inspector.
- Deck and structural integrity — Waterfront decks, docks, and exterior stairs take a beating from freeze-thaw cycles and seasonal humidity. A BCIN-certified designer can assess whether existing structures meet current load and guardrail requirements.

Why Working With a BCIN-Certified Designer Matters Here
This is where having the right team in your corner makes a significant difference. BCIN certification means your designer is qualified to prepare and submit permit drawings directly to the municipality — which streamlines the approval process considerably when you're working against a licensing deadline.
At BRHDG, we understand how Northern Ontario's climate and construction environment shapes what's practical and what's code-compliant. Cottage-country properties present unique challenges: irregular lot sizes, shoreline setbacks under the District of Muskoka Official Plan and applicable Conservation Authority regulations, aging infrastructure, and seasonal construction windows that can be frustratingly short. We design around these realities, not in spite of them.
Whether you need a formal compliance review, a set of stamped drawings for a permit application, or a phased upgrade plan that fits your budget and your rental season, we can help you build a clear path forward.

Practical Steps to Take Before Your Next Rental Season
Don't wait until a guest is booked and a licence is pending. Here's a straightforward action list:
1. Review the Township's licensing checklist — Available on the Muskoka Lakes municipal website. Read it carefully before assuming your property qualifies. 2. Book a site assessment — Have a qualified designer or building professional walk the property with fresh eyes. Issues that seem minor often have code implications. 3. Pull any required permits early — Permit processing timelines in cottage country municipalities can run longer than in urban centres. Build that time into your plan. 4. Talk to your insurer — STR use may require a specific policy endorsement or a commercial liability rider. Confirm your coverage is appropriate for licensed rental use. 5. Document everything — Keep records of inspections, permits, approvals, and correspondence with the Township. You'll need them at licensing time and potentially long after.

The Bottom Line
The Muskoka Lakes STR bylaw isn't going away, and the municipalities surrounding it are watching closely. With full enforcement taking effect May 1, 2026, the window to get your property assessed, permitted, and licensed is shorter than it may feel. Getting compliant now — rather than scrambling later — protects your investment, your guests, and your ability to keep renting.
