Independent New Hampshire Journalism · Northfield, NHCorrection and update, Sept. 22, 2026, 9:33 a.m. EDT: An earlier version of this article said New Hampshire’s rental vacancy rate “hovered around 4%, one of the lowest in the Northeast,” citing the New Hampshire Fiscal Policy Institute. That source reports a 0.6 percent vacancy rate for two-bedroom apartments in early 2023; the roughly 4 percent figure is the Census Bureau’s broader statewide rate (3.9 percent in 2025), and no source supports the regional ranking. The article also gave July 2025 job-openings figures from a Bureau of Labor Statistics page that now reports December 2025 data (25,000 openings; 1.0 unemployed person per opening). Since publication, Manchester adopted its new zoning ordinance (Manchester Ink Link), and the statewide median single-family price set a new record of $580,000 in July 2026 (New Hampshire Bulletin, citing NH REALTORS). We corrected the vacancy passages, updated the job, price and Manchester items, and replaced links to New Hampshire Housing reports that had moved.
Clarification, Oct. 17, 2026, 8:08 p.m. EDT: This article said the New Hampshire Supreme Court has affirmed local authority to treat short-term rentals as “transient” uses distinct from dwelling units, in Working Stiff Partners v. Portsmouth (2019) and later cases. Working Stiff upheld Portsmouth’s ordinance; in Town of Conway v. Kudrick (2023) and Appeal of Hoekstra (2024), the court read Conway’s and Sunapee’s ordinances in favor of the short-term rental owners (New Hampshire Supreme Court opinions). We revised the passage.
Update, Oct. 17, 2026, 8:08 p.m. EDT: A 2026 amendment to the state ADU law, HB 1079 (Chapter 210, effective Aug. 31, 2026), requires towns to allow ADUs converted from structures that existed on or before July 1, 2025 (RSA 674:72). We added it to the list of what changed.
New Hampshire's Housing Challenge: 60,000 Homes by 2030
By GSR Staff
New Hampshire’s housing crunch isn’t a feeling—it’s measurable and severe. Median sale prices have smashed records, apartments are scarce, and employers report more open jobs than jobseekers. State and local leaders are moving on multiple fronts—from a 2025 statewide ADU law to targeted infrastructure grants—but the central challenge remains: adding roughly 60,000 homes by 2030 while protecting the character and environmental quality that Granite Staters cherish. (New Hampshire Housing)
The short of it: where things stood in 2025
- Prices are still near record highs. New Hampshire REALTORS reported a record median single-family price of $566,250 in June 2025; the market cooled slightly to $545,000 by July, but remained historically elevated. (New Hampshire REALTORS; the June figure was later revised to $569,450, per NHPR) The record did not last: NH REALTORS reported a median of $580,000 in July 2026. (New Hampshire Bulletin)
- Buying power has lagged. New Hampshire Housing’s 2025 buyer survey shows 2024’s median single-family sale price (statewide) at $514,000, up 71% since 2019, far outpacing incomes. (New Hampshire Housing)
- Rentals are tight. New Hampshire Housing puts a balanced rental market at about 5% vacancy; it found a 0.6% vacancy rate for two-bedroom apartments in early 2023. The Census Bureau’s broader statewide rental vacancy rate was 3.9% in 2025 (Census Bureau Housing Vacancy Survey, FRED series NHRVAC). (New Hampshire Fiscal Policy Institute)
- The labor market is tight. In December 2025, New Hampshire had 25,000 job openings and 1.0 unemployed person per opening, according to the Bureau of Labor Statistics. (Bureau of Labor Statistics)
Those numbers are the symptoms. The diagnosis comes from the state’s 2023 Housing Needs Assessment: about 60,000 new homes are needed by 2030, nearly 90,000 by 2040, including an immediate shortage in the tens of thousands just to stabilize the market. Permitting would need to rise roughly 36% above recent levels to get there. (New Hampshire Housing)
How we got here: three drivers you can’t ignore
1) Demographics changed faster than land use rules
New Hampshire’s population growth since 2020 has been driven entirely by in-migration, not births—31,500 net new residents despite more deaths than births over the period. Many arriving households also brought higher-than-average incomes, intensifying pressure in for-sale and rental markets. (Carsey School)
2) We underbuilt for years
The state added far fewer homes than demand required through the 2010s. New Hampshire Housing estimates we must increase building permit activity by about 36% versus recent levels to catch up by 2030. (New Hampshire Fiscal Policy Institute)
3) Local zoning made small, modest homes hard to build
The New Hampshire Zoning Atlas catalogs district-by-district rules across 247 jurisdictions and shows just how limited “missing-middle” options—duplexes, triplexes, small multifamily—often are. When the rules mostly allow large lots and single-family houses, you mostly get large lots and single-family houses. (anselm.edu)
2025’s big policy shift: a statewide ADU reset (HB 577)
In July, Governor Kelly Ayotte signed HB 577—a major update to RSA 674:71–73—that rewires how accessory dwelling units (ADUs) work statewide. The law took effect July 1, 2025 and does three consequential things:
What changed (in plain English):
- One ADU allowed by right (no special permits) anywhere single-family homes are allowed—and the ADU can be attached or detached.
- Equal treatment: towns can’t impose extra lot size, setback, frontage, design review, or aesthetic standards on ADUs beyond what applies to a single-family home in the same district.
- Reasonable limits are still allowed: towns may require owner-occupancy (but cannot dictate which unit the owner lives in); may cap ADU size between 750 and 950 sq ft (unless they choose to allow larger); and may require up to one additional parking space only if the principal dwelling already has an off-street requirement.
- Utilities sanity: no mandatory separate septic or water systems if the combined home+ADU meets state standards; separate electric service may not be prohibited.
- No family-only rules and no one-bedroom caps; two bedrooms can be allowed.
- Conversions (2026 amendment): HB 1079 (Chapter 210, effective Aug. 31, 2026) requires towns to allow ADUs converted from structures that existed on or before July 1, 2025, including detached garages, even where they do not meet current setback or lot-coverage rules. (RSA 674:72)
Why it matters: ADUs add gentle, small-scale housing that fits on existing lots, helps seniors age in place, creates new rental options near jobs and schools, and can be financed incrementally by homeowners—not just developers. Best of all, the units are dispersed—which spreads traffic and infrastructure loads.
Money and tools: how projects get from paper to ribbon-cutting
InvestNH and the Affordable Housing Fund
The state’s InvestNH initiative put $100 million of federal ARPA dollars (plus $10 million in follow-on funds) to work on capital, demolition, per-unit, and planning programs—some via NH Housing and some via BEA—to accelerate workforce housing. Those funds paired with the Affordable Housing Fund created a larger runway in 2023–24; NH Housing entered FY2025 with roughly $15.6 million in capital subsidy to begin the year. (NH Economy)
“Housing Champion” designation (RSA 12-O:71–76)
Towns that modernize zoning and streamline approvals can earn Housing Champion status—unlocking infrastructure dollars and per-unit production grants. Applications were open through May 31, 2025; early designees include Keene (December 2024). What’s new here is the state explicitly funding the infrastructure gap—water, sewer, and streets—that often kneecaps otherwise good infill or redevelopment. (NH Economy)
The Housing Appeals Board (HAB)
Since 2020, the Housing Appeals Board offers a faster, less costly route than superior court to appeal local housing-related land-use decisions. Knowing there’s a predictable appellate path can lower project risk and financing costs. (New Hampshire General Court)
Case studies & local motion
- Manchester rewrote its land-use code to enable more “missing-middle” housing, including reduced minimum lot sizes where the urban core meets single-family neighborhoods, after public engagement through 2024–25. The Board of Mayor and Aldermen approved the new ordinance 11-2-1 on Dec. 16, 2025, its first major update since 2001, effective March 1, 2026. (Manchester Ink Link) (manchesternh.gov)
- Keene earned the Housing Champion designation, making it eligible for targeted infrastructure and production grants to speed up projects aligned with local goals. (City of Keene)
- Laconia has used historic-core redevelopment (e.g., Colonial Block Apartments near the Colonial Theatre) to add small units downtown without greenfield sprawl. (Conneston Construction, Inc.)
Rentals, neighborhoods, and short-term rentals (STRs)
New Hampshire communities have wrestled with how short-term rentals intersect with neighborhood stability and housing supply. The New Hampshire Supreme Court has upheld Portsmouth’s treatment of daily short-term rentals as “transient occupancies” excluded from its definition of a dwelling unit in Working Stiff Partners v. Portsmouth (2019). Later rulings turned on each town’s wording and went the other way: in Town of Conway v. Kudrick (2023) the court read Conway’s ordinance to allow short-term rentals in residential districts, and in Appeal of Hoekstra (2024) it reversed a Housing Appeals Board ruling that Sunapee’s ordinance barred the short-term rental of a travel trailer. Policy takeaway: clear, explicit zoning language beats assumptions or silence. (nhhousingtoolbox.org)
The economics under the hood
- Tight labor market. With about one unemployed person per job opening in December 2025, housing availability can limit hiring, especially for new hires relocating from out of state. (Bureau of Labor Statistics)
- In-migration with higher incomes. Pandemic-era movers brought substantial purchasing power, which bid up limited inventory—especially in desirable school districts and near job centers. (Carsey School)
- Property taxes shape the map. New Hampshire’s overall tax burden ranks competitive nationally, but we rely heavily on property taxes—with among the highest effective rates in the U.S.—which can influence where and what gets built (and at what price). (Tax Foundation)
What it would take to actually add 60,000 homes
The needs assessment is blunt: 60,000 by 2030 means more of everything—infill, gentle density, mill conversions, small apartments over shops, small-lot single-family, and ADUs—distributed across all regions. That requires: (New Hampshire Housing)
- By-right small multifamily near jobs, schools, and transit corridors
Allow triplexes and fourplexes on residential lots that already permit single-family. Where infrastructure exists, make approvals administrative and predictable. - ADUs at scale
With HB 577 in effect since July 1, 2025, municipalities can focus on educational toolkits, pre-approved plan sets, and permit concierge services to help homeowners actually build ADUs. (Some towns pair this with small grants or zero-interest loans supported by CDBG or local trusts.) - Infrastructure where it unlocks housing
Target state dollars to water, sewer, culverts, and complete-streets upgrades that unlock infill parcels or mill sites. The Housing Champion program is a lever here—use it. (NH Economy) - Predictable timelines & a known appeal path
Codify time limits on local reviews; keep the Housing Appeals Board resourced so good projects aren’t stranded by uncertainty. (New Hampshire General Court) - Modern parking rules
Right-size or eliminate minimums near downtowns. Even allowing unbundled parking (renting it separately from units) can cut costs and expand affordability. - Workforce Housing Law compliance
RSA 674:58–61 already requires “reasonable and realistic opportunities” for workforce housing. Periodically auditing local codes against this standard—and the Zoning Atlas data—keeps towns on the right side of both the law and the need. (New Hampshire General Court) - Focus on missing-middle builders
Small, local builders and tradespeople are the ones who deliver duplexes, three-flats, and ADUs. Offer fee waivers for small projects, faster inspections, and pre-approved plans to cut carrying costs.
What cities and towns can do (a pragmatic checklist)
- Map your “easy wins.” Use the NH Zoning Atlas to quickly identify districts where small multifamily is nearly possible now; tweak setbacks, lot sizes, and lot coverage to make it actually feasible. (anselm.edu)
- Adopt an ADU how-to. Publish homeowner guides that mirror HB 577 requirements, plus model permit packets and links to financing options.
- Apply (or re-apply) for Housing Champion status. Line up water/sewer projects with direct housing yield, then pull in infrastructure and per-unit grants. (NH Economy)
- Write clear STR rules. If you want to allow STRs, say where and how; if you want to limit them, be explicit. The courts have favored clarity over implication. (nhhousingtoolbox.org)
- Pilot pre-approved small plans. Three or four plan sets (ADUs, duplexes, corner triplexes) that meet your code can trim months off approvals and lower costs.
Data brief: market signals
- Record price (June 2025): $566,250 as first reported (later revised to $569,450). July 2025: $545,000. July 2026: $580,000, a new record. (New Hampshire REALTORS)
- Balanced rental market ≈ 5% vacancy; NH two-bedroom apartments 0.6% (early 2023); Census statewide rental vacancy 3.9% (2025). (New Hampshire Fiscal Policy Institute)
- Homebuyer affordability: Median prices rose ~71% between 2019 and 2024; incomes rose ~26%—a widening gap. (New Hampshire Housing)
- Permit pace must rise ~36%. (New Hampshire Fiscal Policy Institute)

Bottom line
The math is stark but solvable. New Hampshire needs 60,000 more homes by 2030—not skyscrapers and sprawl, but a tapestry of small, well-located units: ADUs, duplexes, three-flats, main-street apartments, and mill conversions. The 2025 ADU law (HB 577) is a major pivot; the Housing Champion program and InvestNH dollars can make infrastructure work; and the Housing Appeals Board keeps the process predictable. If towns modernize codes with surgical precision, builders—big and small—can do the rest.
New Hampshire has changed before without losing itself. We can do it again—add homes, welcome people, keep what’s special—and make “Live Free” mean live here.
