Lower Merion Township, Pennsylvania Building Permit Guide

Lower Merion protects a large share of its building stock through historic districts and a township-wide inventory, and the penalty for getting a demolition wrong is restoration at the owner’s cost, secured as a lien.

The township enforces the statewide code with its own staff from the Building and Planning Department on Lancaster Avenue in Ardmore. What sets it apart from comparable Montgomery County townships is the depth of its historic framework: a survey completed in 1991 identified more than 80 potential historic districts, and the resulting protections reach well beyond the formally designated districts.

Scope: Lower Merion Township in Montgomery County. Narberth Borough is a separate municipality entirely surrounded by the township and permits its own territory.

What requires a building permit in Lower Merion Township?

Local amendments, fee schedules and the choice of third-party agency differ from one municipality to the next, so an exempt list from a neighbouring township is not reliable. An exemption from a building permit is never an exemption from zoning, the energy code, or an electrical or plumbing permit. Confirm scope with the Building and Planning Department before work starts.

Local rules worth knowing

Lower Merion carries a township-wide Historic Resource Inventory alongside its local historic districts, and demolishing an inventoried resource in violation of the ordinance obliges the owner to restore it — with the township able to perform the restoration itself and charge the cost plus an administrative fee as a municipal lien against the property.

Pennsylvania enforces one statewide Uniform Construction Code under Act 45 of 1999, based since January 1, 2026 on the 2021 ICC codes and administered by most municipalities themselves or through certified third-party agencies; counties issue no building permits. Building codes in Pennsylvania

Who handles permitting in Lower Merion Township?

Building permits, plan review, zoning and land development all sit with the Building and Planning Department at the township building in Ardmore, with the Building Regulations Division handling construction permits and inspections.

The two historic bodies were created 20 years apart and serve different populations of property. The review board, created in 1980, has nine members appointed by the Board of Commissioners and reviews applications within the local historic districts; work there needs a certificate of appropriateness before it can proceed. The commission, created in 2000, has seven members and reviews properties on the Historic Resource Inventory outside those districts. Design guidelines finalised in 2022 govern the substance of both reviews. Separately, the township runs a property resale certification: an application is filed ahead of settlement and the certificate confirms that sidewalks and kerbs are sound, house numbers are visible from the street and smoke detectors are installed, with a lower fee where the application arrives 20 or more days before settlement.

In 2025, building permits issued in Lower Merion Township authorized 442 new privately owned housing units, 12 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Residential work here runs through large older houses across the Main Line, many of them inventoried as historic resources even where they are not inside a designated district. Alterations, additions, demolitions and signage all draw a historic question before they draw a code one. Floodplain parcels pick up a further layer: improvements in the Floodplain District are subject to the floodplain overlay provisions, and grading or a fence within the floodplain requires a zoning permit in its own right.

How Pennsylvania contractor credentials work

Commercial permits

Commercial work along the Lancaster Avenue corridor and the township’s business districts is reviewed against the 2021 editions with accessibility on the 2018 standards, alongside zoning, land development and, where the property is inventoried or in a district, historic review. Change in use and change in tenant have their own application route, separate from the construction filing.

Licenses, trade classifications and design professionals

Practically, three credential layers appear on Pennsylvania projects: HICPA registration with the Attorney General on residential home improvement; separately licensed electrical, plumbing and HVAC trades, licensed by the municipality rather than the state; and, on commercial and larger residential work, drawings sealed by a Pennsylvania-licensed architect or professional engineer. Confirm what the Building and Planning Department requires for the specific building before filing.

Pennsylvania has no state contractor licence; contractors doing at least $5,000 a year of home improvement work register with the Office of Attorney General under the Home Improvement Consumer Protection Act. Contractor licensing in Pennsylvania

Lower Merion Township permit costs and fees

Lower Merion sets its own fee schedule by permit type and collects the state Uniform Construction Code surcharge with the permit. Zoning permits, historic review and the resale certification carry separate charges, and the resale certification fee itself is tiered on how far ahead of settlement the application is filed.

Pennsylvania fees are substantially local: the municipality or its certified third-party agency sets the building-permit and plan-review charge, and the state adds only a modest Uniform Construction Code surcharge collected with the permit. Where a municipality uses a third-party agency, that agency’s fee schedule applies. A figure from a neighbouring municipality is not reliable — ask the Building and Planning Department for the schedule in force on your filing date.

Fees are set by the municipality or its third-party agency, plus the flat $4.50 state Uniform Construction Code fee on each permit. Permit fees in Pennsylvania

Trade permits and who may pull them

Trade work follows the Uniform Construction Code; electrical, plumbing and HVAC licences are issued locally where they exist, not by the state. Trade permits in Pennsylvania

How to apply for a Lower Merion Township building permit

Review, corrections and what actually causes delay

In Pennsylvania, the first cause of delay is uncertainty over who enforces the code — filing with the municipality when it uses a certified third-party agency, or not realising that in a municipality that has opted out of local enforcement, homeowners must hire a certified third-party agency themselves. After that come a missing HICPA registration or local trade licence, energy-code and plan documentation, and, along the state’s rivers, floodplain requirements that were not addressed up front. Build the plan-review time into the schedule and confirm the checklist with the Building and Planning Department before filing.

A Pennsylvania permit lapses if work does not start within 180 days or stops for 180 days, and lasts no more than 5 years; residential applications must be decided within 15 business days. Permit validity in Pennsylvania

Inspections in Lower Merion Township

Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and energy-code compliance, fire systems on commercial work, and final, with a use-and-occupancy certificate before the building is used. Lower Merion inspects through the construction sequence, and the property resale certification is a separate process running on its own 30 to 60 day timetable ahead of settlement rather than as part of the construction final.

Pennsylvania inspections follow the code edition in force when the permit was applied for, and are carried out by a certified code official — the municipality’s own inspector or its certified third-party agency, the city department in Philadelphia and Pittsburgh, the Department of Labor and Industry for commercial work in opted-out municipalities, or a third-party agency the owner hires. Keep the approved plans and the energy-code documentation on site for the inspector to check against, and confirm the notice the Building and Planning Department needs and its inspection windows.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, energy-code documentation and your correction responses available on site.

Lower Merion Township permit search and official resources

Permit records in Pennsylvania sit with the authority that issued them — the municipality or its certified third-party agency, or the city department in Philadelphia and Pittsburgh. Where the Building and Planning Department is the authority for Lower Merion Township, it holds the building permit, the inspection history and the use-and-occupancy certificate. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — open permits and missing certificates are a common closing problem.

Frequently asked questions

Why are there two historic bodies in Lower Merion?

They cover different property. The Historical Architectural Review Board, created in 1980 with nine members, reviews applications within the local historic districts. The Historical Commission, created in 2000 with seven members, reviews properties on the township’s Historic Resource Inventory that are not inside a local district.

What happens if I demolish a historic resource without approval?

The ordinance requires restoration. Anyone who demolishes a building, structure or site on the Historic Resource Inventory in violation of the chapter must restore it to its prior appearance, and in default the township may carry out the restoration and charge the cost, plus an administrative fee, as a municipal lien against the property. That is in addition to any other penalty.

Is my house on the Historic Resource Inventory?

It may be even if it is not in a designated district. A state-funded survey completed in 1991 identified more than 80 potential historic districts across the township, and the inventory reaches well beyond the formally designated ones. Confirm the status with the department before finalising a design.

What is the property resale certification?

A township requirement filed ahead of settlement. The certificate confirms that sidewalks and kerbs are in good condition, house numbers are visible from the street and smoke detectors are installed. It takes 30 to 60 days, and the fee is lower when the application is received 20 or more days before settlement.

Does the township recommend contractors?

No. The township declines to recommend contractors because of the conflict of interest and liability that would follow. It does keep resident feedback, positive or negative, on file and available for public review.

What contractor credential applies?

Pennsylvania has no statewide general-contractor licence. The township code carries its own contractor licensing chapter, and for residential home improvement the state registration with the Attorney General applies as well. Registration is administrative rather than a skills licence: there is no examination, the fee is $100 every two years, and new-home construction falls outside it. The online registration system has been working again since April 24, 2026 after an outage, and the grace period that followed it closed on the eighth of June 2026, so a current registration number is the expectation now.
