Buying An Accessory Dwelling Unit: Mistakes To Avoid

Thinking about buying an accessory dwelling unit? You're not alone. These small, self-contained homes have become very popular, especially in places like Parksville. Whether you want one for extra income, family, or just more space, an ADU is a smart move—if you do it right.

There are a few common mistakes that can turn your ADU dream into a real headache. Let’s talk about what to avoid so your journey goes smoothly from start to finish.

NOT UNDERSTANDING LOCAL REGULATIONS

Every city has different rules when it comes to building or buying an ADU. What works in one town might not be allowed in another. In Parksville, there are specific zoning and bylaw rules that apply to accessory dwelling units.

Before buying, always check with your local municipality. You might need permits, inspections, or approvals that take time and money. If you skip this step, you could face fines or even be forced to remove your unit. That’s an expensive mistake no one wants.

UNDERESTIMATING THE COSTS

Many people assume ADUs are cheap. While they’re more affordable than full homes, they still come with costs. Some of these are easy to miss.

You’ll need to budget for things like land preparation, utilities, permits, and possibly landscaping. If you're buying a pre-built unit, delivery and setup can also cost more than expected. It’s smart to add a buffer to your budget. Things often cost more than planned, especially with construction.

CHOOSING THE WRONG LOCATION

Location is everything. You might find the perfect unit, but if the property isn’t in a good spot, it can cause problems. Think about access, privacy, sun exposure, and how close it is to the main home.

If you plan to rent it out, you’ll want it to feel private for your tenant. If it’s too close to your own home or hard to reach, renters might not be interested. Pick a spot that makes sense for both function and comfort.

IGNORING THE IMPORTANCE OF DESIGN

Just because an ADU is small doesn’t mean design doesn’t matter. A poorly designed unit can feel cramped, dark, and unwelcoming. That’s the last thing you want, whether you live in it or rent it out.

Look for smart layouts, natural light, and clever storage. A good design will make even the smallest space feel open and livable. Don’t rush this part. Take your time and choose something that really fits your needs.

NOT THINKING LONG-TERM

Buying an ADU is a big investment. You need to think beyond your current situation. Will your needs change in a few years? Could you see yourself downsizing into the ADU later in life?

Make sure the unit you choose is flexible enough to grow with you. Maybe you’ll rent it now and move in later. Or maybe it will become space for aging parents. Keep your future in mind as you decide.

SKIPPING A PROPERTY INSPECTION

If you’re buying a property that already has an ADU, don’t skip the inspection. Just like any other home, an ADU can have hidden issues. Plumbing, electrical systems, roofing, and foundations all need to be checked.

An inspection can uncover costly problems before you commit. It might seem like an extra step, but it can save you thousands down the road. Always know what you’re getting into.

FORGETTING ABOUT TENANT LAWS

Planning to rent your ADU? Make sure you understand tenant laws in your area. In British Columbia, there are clear rules for landlords, even if the tenant lives in your backyard.

You’ll need to follow rules about rent increases, eviction notices, and repairs. Ignoring these laws can land you in legal trouble. Do your homework or talk to a local expert before bringing in a renter.

TRYING TO DO EVERYTHING YOURSELF

It’s tempting to take the DIY route, especially if you’re handy. But building or managing an ADU involves a lot of moving parts. Permits, construction, utility connections, and design choices can be overwhelming.

Consider working with professionals who know how to navigate these projects. Contractors, designers, and city planners can save you time, money, and stress. You don’t have to go it alone.

UNDERESTIMATING HOW MUCH TIME IT TAKES

Even with a solid plan, these projects take time. Permits can take weeks or even months to process. Building or setting up the unit also doesn’t happen overnight.

Be patient and realistic about your timeline. Rushing the process can lead to mistakes or poor decisions. A bit of extra planning now will save you from future frustration.

NOT THINKING ABOUT RESALE VALUE

Accessory dwelling units add value to a property—but only if they’re done right. If you cut corners or go with a poor design, the unit might not appeal to future buyers.

Choose high-quality finishes and energy-efficient systems. Keep the look of the unit in harmony with the main house. Buyers will notice, and it can increase your resale value.

ASSUMING IT WILL ALWAYS BE RENTED

Many people see an ADU as a great rental income source—and it can be. But don’t depend on that income without considering market changes.

Rental demand can shift. There could be times when the unit sits empty. Make sure your budget can handle some downtime. It’s better to be safe than stuck.

OVERLOOKING ACCESSIBILITY

Think about who might use the ADU. Older parents? Guests with mobility issues? A unit with steps, narrow hallways, or high counters might not work for everyone.

Design with accessibility in mind. Features like wider doorways, walk-in showers, and step-free entries can make a big difference. Plus, they increase the unit’s appeal and future value.

WRAPPING UP: KEEP IT SIMPLE AND SMART

Buying an accessory dwelling unit is an exciting step, but it’s not something to rush. The key is to plan carefully, do your homework, and avoid the common mistakes others have made. Keep it simple. Think long-term. Ask for help when you need it.

Accessory dwelling units in Parksville offer amazing opportunities—more space, extra income, or a cozy spot for family. But only if you approach the process with care.

By avoiding these pitfalls, you’ll set yourself up for success. Whether you’re new to the world of ADUs or just looking to make a smart choice, a little guidance goes a long way. Keep your goals in mind, stay flexible, and enjoy the journey. Your perfect ADU might be closer than you think.
