Senate Bill 497 would require local governments in North Carolina to allow “middle housing” in all residential zoning districts, including areas currently zoned for detached single-family homes. The bill defines middle housing broadly to include duplexes, triplexes, fourplexes, fiveplexes, sixplexes, and townhouses, and it requires these housing types to be treated as permitted uses subject to the same basic permit and review process as detached single-family dwellings. Local governments could still regulate middle housing, but not in ways that create unreasonable cost or delay or that effectively limit these homes to less than three stories or a floor area ratio below one.
The bill also places several limits on local regulation. It would prohibit local governments from banning long-term rentals in middle housing, requiring commercial building codes or fire sprinklers, dictating parking layout, or forcing the creation of homeowners’ associations, condominium associations, shared amenities, or private streets. The bill applies only in areas served by public water or sewer infrastructure, and it exempts local historic districts and properties on the National Register of Historic Places. It also states that private covenants and recorded property restrictions remain enforceable except where they conflict with the bill’s new rule that instruments cannot bar middle housing or accessory dwelling units on property otherwise allowed for single-family homes.
In terms of state law impact, the bill would significantly preempt local zoning authority under Chapter 160D by mandating that middle housing be allowed statewide in residential zones and by limiting the kinds of design, development, and review standards local governments may impose. It would also affect property law by voiding certain recorded restrictions that would block middle housing or accessory dwelling units on lots that otherwise permit single-family housing. The bill would therefore expand housing density options and reduce local discretion over residential land use, while preserving some local control over site plan conformity and historic preservation.
The general sentiment reflected by the bill itself is strongly pro-housing and pro-development, with an emphasis on increasing housing supply and affordability. Although no committee transcript or vote history is provided, the structure of the bill suggests support for housing diversification, reduced zoning barriers, and more predictable approval processes for missing-middle housing. The bill’s affordability language also indicates an intent to encourage lower-cost housing production through streamlined regulation and possible fee or infrastructure incentives.
The main points of contention are likely to be local control versus statewide zoning mandates, neighborhood character, infrastructure capacity, and the scope of limits on design standards. Local governments may object to the bill’s restrictions on their ability to require parking, open space, private streets, or association governance, while supporters are likely to argue that these limits are necessary to prevent exclusionary zoning and to make middle housing feasible. The carve-outs for historic districts and utility-served areas may also be important in balancing preservation and infrastructure concerns against broader housing access goals.
The bill would amend Chapter 160D of the North Carolina General Statutes to create a new statewide zoning requirement for middle housing in residential districts. It would preempt local ordinances to the extent they prevent duplexes, triplexes, fourplexes, fiveplexes, sixplexes, and townhouses from being built in areas zoned for residential use, including single-family zones, and it would restrict local governments from imposing certain design, parking, code, and association requirements. It would also invalidate certain post-enactment deed restrictions that conflict with the bill’s allowance of middle housing and accessory dwelling units, while preserving private covenants generally and exempting historic districts.
The bill appears to be framed positively and reform-minded, with a clear policy goal of expanding housing supply and improving affordability by reducing zoning barriers. Because there are no recorded committee discussions or votes in the provided material, there is no direct evidence of opposition or support from legislators, but the bill’s language suggests a strong pro-housing, pro-density posture. The overall tone is that middle housing should be treated as a normal residential option rather than a discretionary or exceptional use.
Likely areas of contention include the bill’s override of local zoning authority, its limits on parking and design standards, and its prohibition on certain local requirements such as sprinklers, commercial code compliance, private streets, and mandatory homeowners’ or condominium associations. Local governments and neighborhood groups may view these provisions as reducing their ability to manage growth, infrastructure, and neighborhood character, while housing advocates are likely to support them as necessary to make middle housing practical and affordable. The bill’s treatment of recorded property restrictions may also raise concern among property owners and developers who rely on covenants to control land use.
