# Townhome lots: how a townhouse subdivision works on the land

A townhome lot is a narrow lot that holds one home in a row of attached homes. The ordinance sets most rules for the whole site, and each lot meets only a few. Common land goes to an owners association, and the declaration decides whether the project is a planned community or a condominium.

> **Quick summary:** This guide explains how a townhouse subdivision sits on the land: the site, the small lots, the common area, and the law that governs ownership. It is for builders and tract buyers who want to know what a townhome plan asks of a tract. The key takeaway: most zoning rules apply to the whole site, the lot rules are thin, and the ownership form decides who owns the land between the buildings.

## What a townhome lot is

A townhome lot is a lot that holds one home in a row of homes with shared side walls. Each home sits on its own lot, and the owner holds that lot in fee simple.

Durham's ordinance gives a clear [definition of a townhouse](https://udo.durhamnc.gov/udo/7_01_Housing%20Types.htm). It is a building of three or more attached dwelling units, except where the ordinance allows fewer. Each unit is on an individual lot, the units line up in a row, and they share side walls.

The lot is often little more than the footprint of the home plus a yard or a parking pad. The rest of the land, such as drives, parking, open space, and stormwater areas, sits in common area lots.

## Site rules and lot rules

A townhouse ordinance applies most of its rules to the whole site and only a few to each lot. That split decides how many homes fit on a tract.

Raleigh's ordinance shows the two layers. It defines a [site](https://udo.raleighnc.gov/sec-151-site) as any lot or group of contiguous lots that one owner controls and assembles for development. Its [townhouse standard](https://udo.raleighnc.gov/sec-223-townhouse) then sets these rules:

| Rule | Applies to | R-6 | R-10 |
|---|---|---|---|
| Net site area per unit (min) | Site | 4,500 sq ft | 3,000 sq ft |
| Site width (min) | Site | 50 ft | 45 ft |
| Outdoor amenity area (min) | Site | 10 percent | 10 percent |
| Side site boundary setback (min) | Site | 10 ft | 6 ft |
| Rear site boundary setback (min) | Site | 20 ft | 20 ft |
| Internal building separation (min) | Between buildings | 10 ft | 10 ft |
| Lot width (min) | Each lot | 16 ft | 16 ft |
| Lot area (min) | Each lot | none | none |

The same section limits a townhouse development in the R-2 and R-4 districts to two dwelling units. So the district decides whether a row of homes is possible at all.

**Unit count.** In this model, net site area per unit sets the yield. Divide the net site area by the per-unit minimum, then check the district density.

**Lot width.** Raleigh measures [lot width](https://udo.raleighnc.gov/sec-152-lot) for a townhouse lot that does not front a public street at the front property line, across the drive aisle or parking lot it faces. That rule lets lots face a private drive.

Durham sets its rules by tier. Its [townhouse table](https://udo.durhamnc.gov/udo/7_01_Housing%20Types.htm) sets a street yard of 25 feet in the Suburban Tier and 12 feet in the Urban and Compact Neighborhood tiers. It measures the 20-foot rear yard from the boundary of the development site. Where an improved and maintained alley exists, all vehicle access comes from the alley.

> **The short version:** The site carries the area, width, perimeter setback, and open space rules. The lot carries a minimum width. Count the homes from the site rules, then draw the lots.

## Townhome or condominium

A townhome and a condominium can look the same from the street, but the owner holds different land. The declaration decides which one a project is.

**Condominium.** Under the [North Carolina Condominium Act](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_47C/GS_47C-1-103.html), a condominium is real estate where portions are designated for separate ownership and the remainder for common ownership by those owners. The unit owners hold undivided interests in the common elements. The [act applies](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_47C/GS_47C-1-102.html) to all condominiums created in North Carolina after October 1, 1986.

**Planned community.** Under the [Planned Community Act](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_47F/GS_47F-1-103.html), a planned community is real estate where a lot owner is obligated by a declaration to pay expenses to maintain other lots or other real estate. The common elements are real estate the association owns or leases, other than a lot. A condominium is not a planned community under that definition.

A fee-simple townhouse project is usually a planned community. The owner holds the lot under the home, and the association holds the common area.

| Question | Fee-simple townhome | Condominium |
|---|---|---|
| What the owner holds | A platted lot | A unit plus a share of the common elements |
| Who holds the common land | The association | The unit owners together |
| Governing statute | Chapter 47F, the Planned Community Act | Chapter 47C, the Condominium Act |
| Each home on its own lot | Yes | No |

Size matters for the statute. The Planned Community Act [applies](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_47F/GS_47F-1-102.html) to planned communities created on or after January 1, 1999. It does not apply to one with no more than 20 lots, unless the declaration says it does. A North Carolina real estate attorney drafts the declaration and decides the form.

## The owners association and the common area

The owners association holds the common area and collects the money to maintain it. A townhome project depends on it more than a detached subdivision does, because the drives, parking, and open space sit outside the lots.

The declaration sets what the association maintains, such as roofs, exterior walls, private drives, stormwater controls, and open space. It also sets the assessments. Under [the Planned Community Act](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_47F/GS_47F-3-116.html), an assessment unpaid for 30 days or longer becomes a lien on the lot when the association files a claim of lien with the clerk of superior court.

**Shared walls.** The declaration or a recorded party wall agreement says who repairs a shared wall. Have the attorney confirm which document controls.

**Building code.** The North Carolina Residential Code covers townhouses not more than three stories above grade plane with a separate means of egress. The [state's amendment record](https://www.ncosfm.gov/2017-2024-approved-amendments-241210residential-code/open) shows that scope. Building inspections answers fire separation and sprinkler questions for a taller or different building.

## What a tract buyer checks

A tract buyer checks whether the district allows a row of homes, then how many the site rules allow. These are the checks, in order:

1. **District.** Confirm the zoning district allows the townhouse type and how many units a building may hold.
2. **Yield.** Apply the site area per unit and the density cap to the net site area. See [How many houses fit on an acre](/insights/how-many-houses-per-acre/).
3. **Perimeter.** Take the site setbacks, buffers, and any stream buffers off the edges.
4. **Access.** Check whether the ordinance requires alley access and whether lots may face a private drive.
5. **Open space and stormwater.** Reserve the required amenity area and the stormwater control area. See [Stormwater rules for a new subdivision in North Carolina](/insights/stormwater-rules-for-subdivisions/).
6. **Utilities.** Confirm a water and sewer connection for each home. See [Sewer, septic, or a package plant](/insights/sewer-septic-or-package-plant/).
7. **Covenants.** Read any recorded restriction on the tract that limits it to detached homes. See [Restrictive covenants: what they are and how to find them](/insights/restrictive-covenants/).

A townhome plan is one way to hold more homes on part of a tract. A conservation design is another, and it puts the saved land into open space. See [Conservation subdivision: clustered lots and open space](/insights/conservation-subdivision/). On a single infill lot, a duplex or a two-unit townhouse follows different rules. See [Missing middle housing: duplexes, triplexes, and townhouses on single lots](/insights/missing-middle-housing/).

## Who answers the question

Planning staff answer the zoning question. Other professionals answer the rest.

- **Planning staff** confirm the district, the site rules, and the plat review path.
- **A licensed land surveyor** prepares the plat with each townhome lot and common area lot.
- **A professional engineer** designs the drives, utilities, and stormwater controls.
- **A North Carolina real estate attorney** drafts the declaration and decides between a planned community and a condominium.
- **Building inspections** answers the building code questions for the attached homes.

The public record shows the zoning district, the tract lines, and any recorded covenant. It does not show sewer capacity or the yield after buffers. We read the record in a fixed order and hand you the open questions.

## Key recap

- A townhome lot holds one home in a row of attached homes, and the owner holds the lot in fee simple.
- Most townhouse rules apply to the whole site: area per unit, width, perimeter setbacks, and open space. The lot carries a minimum width.
- A condominium owner holds a unit and a share of the common elements. A townhome owner holds a lot, and the association holds the common area.
- The Planned Community Act applies to planned communities created since January 1, 1999, with an exception for 20 lots or fewer.
- Count the homes from the site rules, then check access, open space, stormwater, utilities, and covenants.

## Questions

### What is the difference between a townhouse and a condo?

A townhouse owner holds a platted lot under the home, and the owners association holds the common area. A condominium owner holds a unit and an undivided share of the common elements. The declaration, not the building style, decides which one a project is.

### How wide is a townhome lot?

The ordinance sets the minimum. Raleigh's townhouse standard sets a minimum lot width of 16 feet in its residential districts that allow townhouses, with no minimum lot area. Other towns set their own widths.

### Do I need an HOA for a townhome development?

In practice, yes. The drives, parking, open space, and stormwater controls sit outside the lots, and an owners association holds and maintains them under a recorded declaration. A North Carolina real estate attorney drafts the declaration.

### How many townhomes fit on an acre?

The site area per unit and the district density decide it, after buffers, streets, and open space come off. One acre is 43,560 square feet, so divide the net site area, not the gross acre, by the per-unit minimum.
