Home improvement in Hillsborough

Hillsborough is the Orange County seat and one of the oldest towns in the North Carolina Piedmont. Its downtown and the streets around it hold houses and public buildings from the colonial era through the early 1900s, many inside the town's historic district. Beyond that core are mill-era and mid-century neighborhoods, newer subdivisions along the Eno River and the I-85/I-40 corridor, and rural homes on wells and septic.

A Hillsborough project often has two separate approval tracks, one with the town and one with the county. Knowing which is which saves weeks.

Town approvals vs. county permits

• The Town of Hillsborough issues zoning compliance permits and, inside the historic district, Certificates of Appropriateness or staff approvals for exterior work. The town also handles its own zoning and stormwater rules.
• Orange County Planning and Inspections issues and inspects building, electrical, mechanical and plumbing permits for the Town of Hillsborough and for rural Orange County. Building permit documents go to the county's permit email or portal; trade permit documents go to a separate county inspections email. Fees can be paid online in the county's permit portal. The county's office is open 8 a.m. to 5 p.m. weekdays, and in-person meetings must be scheduled in advance.

Chapel Hill, Carrboro and Mebane have their own building departments, but Hillsborough does not. If you have a Hillsborough address outside town limits, you'll deal with the county for zoning as well.

The historic district

Inside Hillsborough's historic district, exterior construction, alteration, restoration and demolition need approval before work begins. That approval is either:

• a Certificate of Appropriateness from the Historic District Commission, or
• a staff approval for work the town's design standards classify as minor work or ordinary maintenance.

The town's design standards list which items fall under minor work and maintenance. Bigger changes, and anything that doesn't fit the standards, go to the commission. Commission applications have firm submission deadlines ahead of each meeting, so build the review calendar into your schedule.

What this means for common projects:

• Window replacement on a historic house is reviewed closely. Repair is usually the path of least resistance.
• Porch rebuilds should match original details: columns, railings, decking direction and trim.
• Additions generally need to be set back and subordinate to the historic house, so they don't overwhelm it from the street.
• Roofing with a material change usually needs review; like-for-like repair may qualify as maintenance.

A realistic timeline for a historic-district project

For a project that needs the commission, plan backward from the start date you want:

1. Talk to town planning staff about whether the work is minor, maintenance or commission-level.
2. Prepare drawings and material samples, with photos of the existing conditions.
3. Submit by the deadline for the meeting you're targeting. Late applications roll to the next month.
4. Attend the meeting, where the commission may approve, deny or continue the application.
5. Apply to Orange County for the building permit once the town approves, with the zoning compliance permit in hand.
6. Build and inspect. Any change from the approved design may need to go back to the town.

Staff-level approvals are much faster, which is one reason many owners scope projects to repair rather than replace.

Climate, soil and the river

Orange County is in climate zone 3A in the 2024 North Carolina Energy Conservation Code. Hillsborough's older houses mostly sit on crawl spaces or stone and brick piers, where moisture and wood rot are the usual problems. Lots near the Eno River and its tributaries may have floodplain or stream buffer limits on decks, additions and grading, so ask the town early. Piedmont clay and rock make digging harder; call NC 811 before you do.

HOAs

The historic core and older neighborhoods mostly have no HOA, though the historic district has its own design review. Newer subdivisions usually have HOAs with architectural rules.

Projects that make sense in Hillsborough

• Wood window repair, storm windows and restoration in historic houses. See windows.
• Exterior painting with trim and siding repair. Hire painters who follow lead-safe practices for pre-1978 houses. See exterior painting.
• Roof replacement and repair, with historic review where materials change. See roofing.
• Porch restoration and new screened porches. See porches and decks.
• Kitchen and bath remodels inside older floor plans. See kitchen remodeling and bathroom remodeling.
• Heat pumps or mini-splits in houses without good ductwork. See HVAC.
• Additions on larger lots, designed to respect the historic district standards. See home additions.

Rebates and licensing

Duke Energy customers can use Smart $aver rebates on qualifying HVAC, insulation and air-sealing work through participating contractors. Rural homes may be on an electric cooperative instead. North Carolina requires a licensed general contractor for jobs of $40,000 or more. Check one on the NCLBGC license search.
