Pennsylvania 2025-2026 Regular Session

Pennsylvania Senate Bill SB1256

Introduced
4/6/26  

Caption

In general provisions, further providing for definitions; and, in zoning, providing for accessory dwelling units and for public availability of public utility fees.

Summary

SB1256 would amend Pennsylvania’s Municipalities Planning Code to require municipalities to allow accessory dwelling units (ADUs) on lots with single-family homes. The bill defines an ADU as a self-contained living unit on the same parcel as a single-family dwelling and permits ADUs to be attached, detached, or contained within the primary home, including units that are already constructed or may be constructed. Municipalities would have to create an ordinance process for permitting at least one ADU per eligible parcel, and the bill sets statewide limits on size, application review, and local regulation. The bill also establishes a streamlined permitting framework for ADUs. Local governments would have to approve or deny completed applications within 30 days, or 60 days if additional review is needed, and applications would be deemed approved if the municipality misses the deadline. The bill limits application and review fees to $250 each, prohibits permit renewal requirements, and bars municipalities from imposing a range of restrictions such as owner-occupancy mandates, parking minimums, design matching rules, familial relationship requirements, impact fees, and certain setback, lot size, or frontage standards that are more restrictive than those for single-family dwellings. It also requires public utilities regulated by the Pennsylvania Public Utility Commission to post estimated connection fees and timelines online, including separate fee schedules for ADUs. If enacted, the bill would significantly preempt local zoning authority by standardizing how municipalities must treat ADUs and by voiding inconsistent local ordinances after January 1, 2027. It would also create new statutory obligations for utilities to disclose service-connection costs and timeframes for new housing, including ADUs. The practical effect would be to make it easier and faster for homeowners to add rental or secondary living space on existing residential lots across the Commonwealth. The general sentiment reflected by the bill text is strongly pro-housing and pro-ADU, with an emphasis on reducing local barriers, increasing housing supply, and simplifying permitting. Because there are no committee transcripts or recorded votes provided, there is no documented public debate in the supplied materials, but the structure of the bill suggests support for housing affordability and infill development. The absence of recorded votes or hearing remarks means no formal sentiment from legislators can be inferred beyond the bill’s policy direction. The main points of contention likely involve local control, neighborhood character, infrastructure capacity, and municipal revenue. The bill limits municipalities’ ability to require parking, owner occupancy, design conformity, impact fees, or stricter dimensional standards, which could draw objections from local governments and residents concerned about zoning flexibility and enforcement costs. Utilities and municipalities may also object to the administrative burden of meeting the bill’s disclosure and permitting timelines, while supporters would likely argue that these limits are necessary to make ADUs a realistic housing option.

Impact

The bill would amend the Pennsylvania Municipalities Planning Code to add statewide rules for accessory dwelling units and public utility fee transparency. It would require municipalities to allow at least one ADU on a lot with a single-family dwelling, establish a uniform permit-review process, and preempt local ordinances that conflict with the new standards after January 1, 2027. It would also require PUC-regulated utilities to publish estimated connection fees and timelines, including separate classifications for ADUs.

Sentiment

No committee transcript or vote history is provided, so there is no recorded legislative debate to summarize. Based on the bill’s text, the measure appears to be framed as a housing-supply and permitting-reform bill, suggesting generally supportive sentiment among its sponsors and likely housing advocates. The policy is likely to be controversial with municipalities and some neighborhood stakeholders because it reduces local zoning discretion and limits common ADU restrictions.

Contention

The likely points of contention are the bill’s preemption of local zoning authority and its restrictions on municipal conditions for ADUs. Municipalities may object to being required to permit ADUs, to the ban on owner-occupancy and parking requirements, and to the limits on fees and design standards. Supporters would likely favor these provisions as necessary to prevent local barriers from blocking small-scale housing expansion and rental opportunities.
