Apartment Weight Limits and Terriers: Which Breeds Make the Cut?

Most apartment weight limits hover around 20-25 lbs, which means the smaller and mid-size terriers fit easily while the bigger ones get caught. If you’re choosing a terrier for apartment life, the breed’s typical adult weight is the single number that decides whether you’ll clear the lease.

There’s no national rule here. Each landlord, building, or HOA sets its own cap. The most common limits land around 20-25 lbs, some buildings stretch to 35-50 lbs, and a few have no limit at all. So the first step is always reading the lease and getting the exact number in writing. Once you have it, you can match it against the breed.

Here’s how the common terriers stack up.

Comfortably under 25 lbs

These breeds clear most standard caps without drama:

• Yorkshire Terrier (~7 lbs) — Toy-size and well under almost any limit. The classic apartment terrier.
• Border Terrier (~11-15 lbs) — Compact and consistently under the line.
• Cairn Terrier (~13-14 lbs) — Small, sturdy, and easily within range.
• Jack Russell Terrier (~13-17 lbs) — Fits on weight; just plan for the high energy.
• West Highland White Terrier / Westie (~15-20 lbs) — Reliably under 25 lbs.
• Scottish Terrier (~18-22 lbs) — Near the top of this group but still typically under a 25-lb cap.

If your building uses a 20-25 lb limit, anything in this list is a safe bet on weight alone. For more on temperament and noise fit, see our Best Apartment-Friendly Terrier Breeds guide.

The borderline cases

A couple of breeds have wide weight ranges, so the same breed can pass or fail depending on the individual dog and the cap:

• Boston Terrier (~12-25 lbs) — A smaller Boston sails under, but one at the top of the range bumps right against a 25-lb limit.
• Rat Terrier (~10-25 lbs) — Comes in size varieties; the smaller ones fit comfortably, larger ones flirt with the cap.

For these, weigh the actual dog (or ask the breeder/shelter for the adult estimate) before you sign. A building with a 35-lb limit removes the worry entirely; a strict 20-lb cap may not work for a larger individual.

The 25-40 lb middle

These breeds clear a generous 35-50 lb limit but get caught by the common 25-lb cap:

• Staffordshire Bull Terrier (~24-38 lbs) — Often over a 25-lb limit, usually fine under a 40-lb one. Note that some buildings also restrict bully-type breeds regardless of weight, so check breed rules too.
• Soft Coated Wheaten Terrier (~30-40 lbs) — Almost always over a 25-lb cap; fits a more generous limit.

Likely over the limit

The big terriers exceed nearly every common apartment cap:

• Bull Terrier (~50-70 lbs) — Over most limits, including the generous 35-50 lb ones at the high end.
• Airedale Terrier (~50-70 lbs) — The “King of Terriers” is simply too large for typical weight-restricted buildings.

If you’ve got your heart set on one of these and your building has a weight limit, you’re generally looking at finding a different building, negotiating with the landlord, or the route below.

When the weight limit doesn’t apply: the ESA exception

There’s one situation where a weight cap legally doesn’t matter. Under the federal Fair Housing Act, an emotional support animal is treated as an assistance animal, not a pet. Per HUD guidance, breed and weight restrictions generally don’t apply to assistance animals, and a landlord can’t charge pet rent or a pet deposit for one. That means a qualifying tenant with, say, an Airedale or a Bull Terrier can be entitled to keep that dog even in a building with a 25-lb cap.

The catch is that this requires a real qualification. The only document with legal standing is an ESA letter written by a licensed clinician after an actual evaluation of your need. There is no official ESA registry, and the “certificates” or registration cards sold online without an evaluation are decorative — they carry no legal weight. If you think you may qualify, you can start the process of getting a legitimate ESA letter through a licensed provider.

The honest bottom line: if you’re shopping for a terrier and abide by a standard pet policy, pick from the breeds that fit your building’s number. If you genuinely qualify for an ESA, the weight cap stops being the deciding factor.

Related Questions

What’s the most common apartment dog weight limit?

Many apartments cap dogs around 20-25 lbs, though some are more generous at 35-50 lbs. There’s no national standard, so the number is set by each landlord or HOA. Always confirm the exact limit in the lease before you commit to a breed.

Which terriers usually fit under a 25-lb apartment limit?

Small and mid-size terriers comfortably clear 25 lbs: Yorkshire Terriers (~7 lbs), Cairn Terriers (~13-14 lbs), Border Terriers (~11-15 lbs), Jack Russells (~13-17 lbs), Westies (~15-20 lbs), and Scottish Terriers (~18-22 lbs). Boston Terriers (~12-25 lbs) and Rat Terriers (~10-25 lbs) fit at the smaller end but can press against a strict cap.

Which terriers are usually too big for apartment weight limits?

The larger terriers typically exceed common caps. Bull Terriers and Airedales run ~50-70 lbs, Soft Coated Wheatens ~30-40 lbs, and Staffordshire Bull Terriers ~24-38 lbs, which puts them over most 25-lb limits and often over 35-lb ones too.

Can a weight limit keep out my emotional support animal?

No. Under the federal Fair Housing Act, an emotional support animal is an assistance animal, not a pet. Per HUD guidance, breed and weight restrictions generally don’t apply, and the landlord can’t charge pet rent or a pet deposit. You need a valid ESA letter from a licensed clinician.
