Executive Summary

Development Pipeline

Industrial & Specialized Projects

Entitlement Risk

Approval Patterns

• Sustainability and Clean Energy: Projects advancing solar use or energy efficiency are prioritized, with new ordinances clarifying that rooftop solar is a permitted accessory use .
• Infill Redevelopment: The city favors projects that reuse existing footprints or consolidate parking, provided they contribute to public infrastructure like trails .
• Public Utility Maintenance: Infrastructure improvements, such as Eversource’s line extensions, receive consistent approval for necessary tree removals .

Denial Patterns

• Excessive Relief Requests: The ZBA denies variances for projects seeking "more and more relief" in multiple dimensions (setbacks, height, coverage) without proving a unique property hardship .
• Speculative Use Changes: Applications for "storage" that function as unpermitted office or residential space in restricted zones face high rejection or deferral rates .

Zoning Risk

• Industrial Erasure: The Economic Development Commission and Planning Board are targeting Office Research and Industrial districts for conversion to higher-value Gateway zones .
• Solar Overlays: New zoning definitions for residential and commercial solar are being established to reduce permitting barriers .
• State Housing Mandates: Recent state legislation has stripped local control over ADU and parking minimums, forcing a shift in city development standards .

Political Risk

• Anti-State Preemption Sentiment: The Council and School Board are organizing against state-level bills like universal open enrollment (HB 751) and housing mandates that they believe destabilize local budgets .
• Fiscal Pressure: Rising costs in healthcare and school insurance are driving a push for departmental consolidations and potential reductions in city staffing .

Community Risk

• Wetland Buffer Sensitivity: Neighborhood and conservation advocates closely monitor any development within 100-foot wetland buffers, often demanding extensive mitigation and signage .
• Neighborhood Density Concerns: Residents in established areas like Humphreys Court have successfully lobbied against "infill" subdivisions that they claim compromise neighborhood character .

Procedural Risk

• Construction Management Plan (CMMP): Large-scale redevelopments now routinely face requirements for a CMMP to manage traffic and neighborhood complaints during construction .
• Third-Party Oversight: The city increasingly mandates third-party oversight for any utility work within the public right-of-way .

Key Stakeholders

Council Voting Patterns

• Fiscal Accountability Bloc: Councilor Tabor and Councilor Cook are leading efforts to find efficiencies through attrition and service consolidation (IT, custodial) to manage a projected 5% tax increase .
• Logistics/Infrastructure Skeptics: Most council members prioritize residential growth over industrial expansion, as seen in the push for Gateway rezoning .

Key Officials & Positions

• Douglas McCacron (Mayor): Driving the 2035 Master Plan with a heavy focus on housing action plans and sustainability .
• Lisa Rappaport (School Board Chair): Leading local opposition to state-level education and enrollment policy shifts .
• Max (City Arborist): Holds significant influence over project-related tree removals and replacement species selection .

Active Developers & Consultants

• Mark McNabb (McNabb Properties): Highly active in downtown commercial and mixed-use redevelopments, including the 134 Pleasant Street project .
• Haley Ward (Engineering): The primary technical consultant for major site plan reviews and Gateway conversions .
• Altus Engineering: Active in complex downtown multifamily redevelopments and historic restorations .

Analysis & Strategic Insights

Industrial Pipeline Momentum vs. Entitlement Friction

Portsmouth is transitioning toward a "Gateway" economy that prioritizes high-density residential over traditional industrial use. Momentum for new manufacturing or warehouse space is minimal within the city core; developers should instead focus on the Pease International Tradeport for industrial-scale logistics .

Probability of Approval

• Solar/Green Energy: High. The city is codifying solar as an accessory use by right to meet climate goals .
• Downtown Mixed-Use: Moderate. These projects are policy-favored but face intense scrutiny over stormwater, parking easements, and construction management .
• Non-Conforming Subdivisions: Low. The ZBA has set a high bar for physical hardship, frequently denying applications motivated by economic gain .

Strategic Recommendations

• Leverage State Parking Preemption: Use RSA mandates to limit parking requirements to one space per unit, even if local character-based zoning suggests more .
• Prioritize Wetland Mitigation: Any buffer encroachment must be accompanied by a net reduction in impervious surface and clear, permanent markers to gain Conservation Commission support .
• Engage on "Future of Work": The EDC is forming working groups on the "future of work" and infrastructure (5G/Smart City); developers of tech-flex or R&D space should engage early to shape these regulatory frameworks .

Near-Term Watch Items

• 2035 Master Plan Outreach: Ongoing business community surveys will determine the final extent of industrial-to-residential conversions .
• Water/Sewer Rate Hikes: A follow-up work session in March 2026 will finalize new rate structures intended to offset declining industrial usage .
• HB 1648 (Homestead Exemption): The city is tracking state legislation that could significantly shift the tax burden toward commercial and industrial properties .
