Thinking about adding an Accessory Dwelling Unit (ADU) to your property? 

Wondering if an architect is needed?

Let’s dive straight into the details to see whether an architect is something you need to worry about or not.

What is an ADU?

An ADU is a secondary housing unit on a single-family residential lot.

These can be attached or detached, and are great ways of adding space, increasing property value, or generating rental income.

Do You Need an Architect for an ADU?

Not always

Like with most things in life, the answer isn’t clear-cut, and it depends on the ADU project you have in mind.

Here are two situations to consider, and whether an architect is useful:

  • Standard/Simple Plans: There are pre-approved ADU plans (see some examples here) available that do not need an architect to look over.
  • Custom Designs: For unique designs or challenging sites, an architect can be crucial.

Generally speaking, hiring an architect isn’t a bad idea in most cases, as their expertise can come in handy.

However, if you’re happy to use a pre-approved plan as is, then it could be an unnecessary cost.

Advantages of Hiring an Architect

Making the decision of using an architect doesn’t need to be complicated; it’s generally an argument of whether spending the money is worthwhile for an easier process and a more custom design.

Here’s a recap of all the benefits that an architect can provide so you can see whether it’s worth it for you or not.

Expert Design

Architects provide customization that will get approved under your local codes.

This one can’t be said enough – getting approval for a custom ADU can take forever, and without an architect with ADU experience in your area, you simply won’t be able to build a custom ADU to your liking.

Maximizing Space

Another great thing about architects is that they know how to make the most out of a space, which is particularly useful for ADUs.

Their expertise helps in designing layouts that make the most of limited space, often incorporating multifunctional areas and innovative storage solutions.

Sreamlined Process

Architects can help a lot with things like permits and construction, saving you both time and stress.

They are familiar with the local building codes and regulations, which means they can streamline the approval process. 

They also coordinate with contractors and oversee the construction to ensure the project stays on track and within budget.

Long-Term Value

Hiring an architect leads to a more custom design in most cases, which means your ADU and property will be worth more to the right buyer.

This goes both ways, of course, but a lot of people place value on custom ADUs.

Customization

Pre-approved plans are great, but do you really want an ADU that is the same as X amount of others?

Architects can make your dream come to life, and even suggest customisations you might have not even considered in the first place.

This is particularly beneficial if you have a unique property layout or specific aesthetic preferences.

When Can You Skip an Architect?

There are some cases where skipping an architect is a viable option.

This doesn’t necessarily mean it’s easier, though, often, the investment into an architect is more than worth it.

Here are a few situations where you can get away without hiring an architect.

Pre-Approved Plans

If you’re going ahead with a pre-approved plan and are not interested in any customisation – like at all -then hiring an architect can be pointless.

Simple Projects

If you’re just looking to build a simple ADU using a pre-approved plan with zero changes to the scope, an architect could be a wasted expense.

However, even simple projects can benefit from professional input to ensure they are executed correctly and efficiently. 

If you try to take things on yourself, especially if you have no experience with this type of construction, you may encounter issues with submitting the plans and getting them approved.

Architect Costs

The cost of hiring an architect is obviously a big factor that will determine whether it’s worth it or not for many people.

Architects cost an average of $2,000 to $20,000 for basic plans, however the rate they charge can vary a lot. This can be a pretty big downside to the argument of hiring an architect, however the price is very often worth it to create a more custom design.

FAQs

Can I use a pre-approved plan? 

Yes, many cities offer these plans to streamline the process. They are typically designed to meet local zoning and building regulations, making them a convenient option for homeowners.

Are there benefits to hiring an architect, even for simple projects? 

Yes, an architect can ensure the project is well-integrated with your existing home and meets all regulations. They can also help identify potential issues early on, saving you time and money in the long run.

So There You Have It

Adding an ADU to your property can be a fantastic investment, and the question of whether you need an architect depends on your project’s complexity. 

Looking to build a highly customized ADU and don’t want the headache of dealing with restrictions? Hiring an architect is the best option.

If you’re happy with a pre-approved plan, the funds you would use on an architect would be better spent on furnishings.
