Montgomery Township, Montgomery County, Pennsylvania Building Permit Guide

In Montgomery Township, the Department of Planning and Zoning (215-393-6920) issues building, plumbing, mechanical, electrical and zoning permits and carries out the building inspections; the township has no in-house electrical inspector, so electrical plans and inspections go to an authorized third-party agency. The Board of Supervisors adopted the 2026 Fee Schedule on January 5, 2026: an addition or alteration costs $150 up to $7,000 of estimated cost plus $10 per additional $1,000, and new houses are priced from building valuation data. The township says residential permits typically take 2 to 3 weeks.

What requires a building permit in Montgomery Township?

The township’s rule is broad: a building permit is needed before any addition, alteration, demolition, replacement or new construction. Its list of common projects shows how far that reaches.

Fences may not sit directly on the property line (a setback of at least 2 inches is recommended) and the finished side must face the neighbor; a fence crossing an easement needs a recorded fence easement agreement. Every exterior project in a homeowners’ association needs a copy of the association’s approval. Any water 24 inches or deeper meant for swimming is a pool, and inflatable on-ground pools are not exempt from the 48-inch barrier rule; downspouts, floor drains and sump pumps may never be tied into the sanitary sewer.

What Montgomery Township decides and what the state holds

The township lists the 2021 International Residential, Building, Fuel Gas, Fire, Plumbing, Mechanical, Energy Conservation and Existing Building codes as modified by the state, with 2018 accessibility provisions, the 2020 National Electrical Code and 2019 sprinkler and alarm standards. Montgomery opted in on July 7, 2004 and kept its earlier local amendments, first written for the 1996 BOCA codes: lower sprinkler thresholds of 5,000 square feet, a Knox Box on all buildings, a five-inch Storz hose connection, and carbon monoxide detectors in homes with fuel-burning heat. Local design values are climate zone 4, seismic zone B, 90 mph wind, 30 pounds per square foot of ground snow and 36-inch frost depth.

Montgomery Township building department: who handles permitting

The Department of Planning and Zoning handles permits, plan review, inspections, zoning, land development and stormwater management; Jesse Hill is the Director of Planning & Zoning and is listed by L&I as the township’s building code official. Electrical plan review and inspection are done by one of six agencies on the township’s electrical inspection policy, hired by the applicant.

Montgomery Township permit types

The township’s Building Permit application, revised in September 2026, covers building, electrical or alarm, plumbing, and HVAC, mechanical or sprinkler permits, with a checklist of common jobs from basement renovations to tenant fit-outs. All contractors on it must be registered before the permit issues, and new construction or new living space heated by an existing system needs Manual J heat-load calculations.

Residential permits

An addition or new single-family house needs zoning, building, electrical, plumbing and mechanical permits. The submittal list asks for two sets of scaled plans: complete floor plans showing how an addition attaches, a foundation plan with footing and wall sizes, reinforcing and drains, framing plans for every floor and roof with truss layouts sealed by a design professional, a wall section with insulation values and anchoring, and electrical and plumbing plans, the electrical set stamped by an approved third-party agency. A pool needs zoning, building and electrical permits and a curb escrow, two sets of drawings showing distances, the fence and gates, and for an in-ground pool a grading plan sealed by a design professional. New-construction plan sets not supplied as PDFs carry a scanning fee of at least $25.

Commercial permits

Non-residential projects use the same application and the township’s non-residential requirements, including a separate packet for Montgomery Mall tenants. A business opening, re-occupying or changing use needs a Non-Residential Use & Occupancy Permit ($300), and a business license may also be required. Truss placards, interior demolition and underground storage tank removals have their own forms. Commercial contractors and builders of new houses register for $50 a year with liability coverage of at least $500,000 per occurrence ($1.5 million for blasting) under Ordinance 15-288; contractors with a state home improvement registration register free.

For tenant improvements and new commercial builds, Alliance handles commercial permit expediting through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning. A zoning review is $125 for new construction and $75 for additions, alterations and accessory structures such as garages, sheds, pools, walkways, driveways and generators. Variances go to the Zoning Hearing Board ($600 residential, $1,200 otherwise).
• Stormwater. A residential project adding more than 1,000 and less than 5,000 square feet of impervious surface pays a fee in lieu of detention of $1.50 per square foot; non-residential stormwater site plans cost $1,500 to review.
• Grading. A grading permit under Chapter 205 has a $1,500 base fee.
• Sewer and wells. The township’s plumbing amendments refer to the Montgomery Township Municipal Sewer Authority’s laterals, and a sewer lateral permit is $45. Private wells, including geothermal wells, need a Montgomery County health department permit first.
• Roads. Openings in a township road or right-of-way need a road occupancy permit ($50 plus $100 per 100 feet) and may need a $500 escrow held for two years; state roads need a PennDOT Highway Occupancy Permit.
• Land development. Plans pay filing fees and escrows, plus the Montgomery County Planning Commission’s Act 247 review fee.

Montgomery Township permit costs and fees

The Board of Supervisors adopted the 2026 Fee Schedule, as amended, by a 5–0 vote on January 5, 2026, effective that day. Most construction lines carry the $4.50 state education and training fee.

Worked from the schedule: a $25,000 addition is $150 plus 18 × $10 ($180), or $330, plus the $75 zoning review and the $4.50 state fee, for $409.50 before its trade permits. A $12,000 roof replacement is $35 plus 11 × $10, or $145, plus $4.50. New houses are priced with the building valuation table in the schedule’s Appendix A; the text refers to valuation data of February 2023 while the appendix prints the February 2025 table, so confirm which figure Planning & Zoning applies before estimating a new home. Work begun without a permit pays double, and a withdrawn permit keeps 10% of the fee (at least $50).

Trade permits and who may pull them

• Electrical: the township does not inspect electrical work. Before applying, have the electrical plans approved by one of the six authorized agencies (Bureau Veritas North America, Code Inspections, Middle Atlantic Electrical Inspections, Middle Department Inspection Agency, United Inspection Agency or Municipal Inspection Corp); fire alarm plans do not need that approval. The rough electrical must pass before the township’s rough framing inspection, and the final electrical before the final use and occupancy inspection.
• Plumbing: priced by fixture, with water laterals at $85 and sewer laterals at $45.
• Mechanical: HVAC is $15 per $1,000 for homes and $20 per $1,000 for other buildings, $150 minimum; gas inserts are $75 and new fireplaces or wood stoves $150.
• Sprinklers and alarms: sprinkler systems are $100 for the first $2,000 plus $30 per $1,000; alarm systems $15 per $1,000, $150 minimum.

The township’s pages set no local electrician or plumber license. Registration is the local requirement: contractors on new houses and commercial jobs, and any contractor without a state home improvement registration, pay $50 a year and file insurance meeting Ordinance 15-288 before a permit issues.

How to apply for a Montgomery Township building permit

Review, corrections and what causes delay

The township says residential applications typically take 2 to 3 weeks depending on volume, and asks for complete applications and drawings to keep review on time; the state’s deadlines are 15 business days for residential and 30 for commercial decisions. Missing electrical agency approval, unregistered contractors, absent HOA approval and plans that need a design professional’s seal are the requirements the forms spell out. Outside plan review or site visits can be billed at consultant rates.

Inspections in Montgomery Township

Each permit comes with its own list of required inspections. Schedule them with Planning & Zoning at 215-393-6920 at least 24 to 48 hours in advance. The township’s inspectors handle the building stages, including the rough framing inspection, which can only be booked once the electrical agency has passed the rough wiring. The final use and occupancy inspection likewise waits for the agency’s final electrical approval.

The first two visits for an item are covered; each further visit on the same matter, such as a third framing inspection, costs $85 and must be paid before more inspections. Work covered up or finished without a permit may need special inspections or tests at the owner’s cost. A use and occupancy permit is issued for new homes ($150) and for non-residential occupancy, re-occupancy and changes of use; the township’s residential occupancy fee applies to new construction only.

The Zoning & Building Certification application ($100 per item) reports a property’s zoning classification, use compliance, variances, open violations, non-conforming status, certificate of occupancy and open or expired permits; the township notes it is not an occupancy permit application.
