What’s an ADU and Can You Build One?

The Backyard Home You’ve Been Hearing About

You might’ve seen the term “ADU” floating around lately, especially if you’re a homeowner or shopping for one.

It stands for Accessory Dwelling Unit, and it’s just a formal way of saying “extra living space” on a single family property.

Think a small backyard cottage, a converted garage, or even a separate side unit built onto your home.

Florida recently passed a law to make ADUs easier to build and Pembroke Pines is already on board.

So…What is an ADU, Really?

An ADU is a secondary housing unit on the same property as a main home.

It has its own entrance, kitchen, bathroom, and living space, basically a small self contained apartment.

Some are attached (like a garage conversion), others are detached (like a backyard unit).

ADUs can be used for:

• Long-term rental income

• Space for extended family or a live-in caregiver

• A home office, guest suite, or future downsizing option

Current Rules in Pembroke Pines

ADUs Are Allowed but only under certain conditions:

• You must own a single family home on a standard city lot (not a duplex or townhome)

• The property must be connected to city sewer (no septic)

• Only one ADU per property

• Size must be 300–1,000 square feet, and the design must match your main home

• You still need to meet zoning rules like setbacks and lot coverage limits

ADUs Are Not Allowed:

• In planned communities (PUDs) like Walnut Creek or Grand Palms

• On properties with septic systems

• If your HOA rules prohibit it

• As short term rentals (Airbnb style is not permitted)

Why Would You Want One?

Pros:

• Rental income from long term tenants

• Extra space for guests, caregivers, or work from home needs

• Boosts resale value and future flexibility

• Addresses housing needs without changing neighborhood character

Cons:

• Construction costs and permitting hurdles

• Parking and privacy considerations

• HOAs may still say no, even if the city says yes

• Utility upgrades may be required

What It Means for Your Property Value

Done right, an ADU can increase your property’s value, especially in a tight housing market.

They appeal to buyers looking for rental income, future flexibility, or multi use space.

But in HOA controlled neighborhoods where they’re not allowed, values may grow more slowly by comparison.

Final Thought

ADUs are one of those ideas that sound simple until you start digging into the zoning, the costs, and the fine print.

I’ve had buyers ask if they can build one, sellers wonder if it adds value, and homeowners try to figure out if it’s even worth the hassle.

From what I see on the ground: a well done ADU can absolutely add flexibility and long term value, especially for people thinking ahead.

But they’re not turnkey.

There are permitting hoops, design rules, and some big question marks in HOA and PUD neighborhoods.

It’s not a one size fits all decision and it doesn’t have to be.

Stay Safe,

Mike
