A young town between two cities

Morrisville is mostly in Wake County, with a part in Durham County. The Census Bureau estimates 32,466 residents on July 1, 2025 (PEP Vintage 2025). Its homes are among the newest in the Triangle: the ACS 2020–2024 5-year estimates put the median year built at 2007, with only about 2.6% of homes built before 1980.

The bigger number is tenure. About 54.6% of Morrisville homes are renter-occupied, compared with 47.7% in Durham and 33.4% in Cary. A renter majority that large points to many apartments and townhomes, and the RTP office parks are close by.

The official weather normals for this whole region are measured at Raleigh-Durham International Airport, close by: about 46 inches of rain a year, July and September the wettest months, about 52 days at 90°F or hotter, and summer dew points in the upper 60s (NOAA 1991–2020).

Where mold shows up in newer apartments and townhomes

These are general patterns for newer buildings, not findings about any property:

  • A leak from upstairs. In stacked units, a washer hose or toilet supply line can wet a ceiling below.
  • The AC closet. Air handlers in interior closets can back up through a clogged condensate line. See HVAC and duct mold.
  • Bathrooms without enough exhaust. Ceiling spotting near the fan is common. See bathroom ceiling mold.
  • Shared walls. Moisture can travel from a neighboring unit, which is one reason a moisture reading helps before anyone opens a wall.

When the source is not obvious, an inspection comes before a removal quote. See mold inspection and testing.

Renters and owners have different first steps

If you rent

Send a written repair request with photos. G.S. 42-42 requires landlords to keep units fit and habitable and lists leaks that contribute to mold as an imminently dangerous condition. Do not withhold rent without a court ruling (G.S. 42-44(c)). The rental mold page has a sample approach. Not legal advice.

If you own or manage

North Carolina does not license mold inspection or remediation companies, so checking credentials is up to you. Ask for IICRC or ACAC credentials, an insurance certificate, a written scope that fixes the moisture source, and independent clearance testing. In a condo or townhome, check with the HOA about shared walls and roofs before work starts.

Non-structural repair work of $40,000 or less in a single-family home usually needs no building permit (G.S. 160D-1110(c)); multifamily work can differ, so your contractor should confirm with the local inspections office. Published ranges for bathroom jobs run $500–$1,500 (Fixr) or $500–$1,000 (This Old House). See the cost guide.

Morrisville and RTP mold questions

I rent an apartment in Morrisville. What should I do about mold?

Tell your landlord or property manager in writing, with photos and dates, and keep a copy. North Carolina landlords must keep rentals fit and habitable (G.S. 42-42), and leaks that contribute to mold are on the state's imminently dangerous list. Keep paying rent unless a court rules otherwise (G.S. 42-44(c)). Not legal advice.

Can a landlord charge me for mold cleanup?

Under G.S. 42-42(a)(8), a landlord may recover the actual and reasonable cost of repairs that are the tenant's fault. Whether mold is the tenant's fault depends on the cause, such as a plumbing leak versus a blocked bath fan. Report problems early and in writing so the record shows when the landlord knew.

Does RTP have its own mold rules?

No. Research Triangle Park is not a separate set of mold rules. North Carolina has no state mold license, and the same landlord-tenant and permit laws apply. For a home or condo, the county and the local inspections office that covers your address handle any rebuild permit.
