Duplexes, Triplexes, and Fourplexes: Property Taxes When You Live in One Unit and Rent the Others
Buying a small multi-family property — a duplex, triplex, or fourplex — and living in one unit while renting the others (sometimes called ‘house hacking’) is a popular entry point into real estate. To wrap up our property types category, here’s how property taxes work for this kind of property.

The Property Is Generally Appraised as a Whole
Unlike a condo, where each unit is typically a separately platted, separately appraised parcel, a duplex/triplex/fourplex is generally a single property (one parcel, one appraisal record) — even though it contains multiple separate living units.
The Homestead Exemption Applies Proportionally
This is the key concept: if you live in one unit of a multi-unit property and rent out the others, the homestead exemption generally applies only to the portion of the property corresponding to your owner-occupied unit — not the entire property. For example, if you live in one unit of a fourplex (and the units are roughly equal in size/value), the homestead exemption might apply to roughly a quarter of the property’s value, not all of it.
How This Compares to Other Scenarios We’ve Discussed
This is conceptually similar to:
- ADUs that are rented out — a smaller-scale version of the same owner-occupied-plus-rented-portion concept
- Mixed-use properties — though there it’s residential vs. commercial use; here it’s owner-occupied vs. tenant-occupied residential use
- Short-term rental scenarios — though there the focus was on short-term vs. long-term use of the same space
The common thread: when only part of a property is your primary residence, homestead benefits generally apply only to that part.
How the Allocation Might Work in Practice
The specific method for determining the homestead-eligible portion (equal split among units, based on relative square footage, or another method) can depend on the appraisal district’s approach and the property’s specific configuration — this is worth confirming directly when applying for the exemption on this type of property.
The 10% Cap Also Applies Proportionally
Following from the above, the 10% appraisal cap would generally apply to the homestead-eligible portion of the property’s value — the rental portions wouldn’t have this protection.
At What Point Does It Become ‘Commercial’?
As properties scale up in unit count, at some point they may be treated more like commercial/income-producing property for valuation purposes — potentially involving income-approach valuation for the property as a whole, even for the portion you occupy. Where exactly this transition happens (and how it affects an owner-occupied unit within a larger property) can vary, and is worth discussing with your appraisal district if you’re scaling beyond a small number of units.
Documentation for Applying
When applying for a homestead exemption on a property where you occupy only one unit, you’ll likely need to provide information establishing both your occupancy of that specific unit and the property’s overall configuration (number of units, relative sizes) to support the proportional allocation.
What If Your Living Situation Changes?
If you move out of your unit (renting it out too) or move into a larger unit within the same property, these changes in occupancy could affect the homestead allocation — similar to how moving generally affects homestead exemption status, updating the appraisal district when your occupancy changes helps keep your exemption accurate.
Wrapping Up the Property Types Category
Across this category, we’ve covered manufactured homes, agricultural valuation, condos/townhomes, vacant land, mixed-use properties, historic properties, and now small multi-family. Together, these show how the core concepts (appraisal, exemptions, the homestead cap, protests) apply across the diverse range of property types found across Texas.

Generally no — it would typically apply only to the homestead-eligible (owner-occupied) portion.
This can vary; as unit count increases, valuation may shift toward commercial/income approaches — worth discussing with your appraisal district for larger properties.
