Building permits, zoning and septic rules in Adams County, Pennsylvania

A building permit is required before starting work covered by Pennsylvania's Uniform Construction Code in Adams County, although emergency repairs may proceed if an application reaches the building code official within three business days¹. The borough or township administers the permit process; Adams County does not issue building permits². Inspections apply to construction or changes to residential buildings and to electrical, gas, mechanical and plumbing systems, and the enforcing office depends on the municipality¹. Covered residential work must remain accessible for foundation, systems, framing, masonry, wallboard and final inspections⁸. A residential building governed by the code may not be occupied until the building code official issues a certificate of occupancy⁸. A qualifying agricultural building can be excluded from the Construction Code Act when it has no habitable space, is not open to the public and is used for a listed agricultural purpose⁹. That exclusion does not settle zoning or other local approvals, so take the proposed use to the municipal building and zoning office².

The borough or township where the parcel sits is the first stop for an Adams County building permit, exemption letter and building official or certified inspection agency². For zoning, the Adams County Office of Planning & Development administers the county ordinance in Germany and Menallen townships and acts as East Berlin Borough's zoning officer under contract; every other municipality administers its own ordinance³. In Germany and Menallen townships, a new structure, addition, sign or change in use requires an Adams County zoning permit, and zoning permit applications follow the county ordinance's fee schedule^3,10. Even there, building permits and septic permits stay with the township, not the county planning office^1,4. Municipal permit procedures vary, so ask the applicable office for its current application sequence and fees⁷. Subdivision and land-development proposals receive county review, but applicants must follow the procedure of the municipality and its applicable ordinance⁷.

Adams County has zoning, but the governing ordinance depends on the parcel's municipality: the county ordinance applies in Germany and Menallen townships, East Berlin Borough has its own ordinance administered by the county planning office under contract, and every other municipality administers its own ordinance³. The county ordinance publishes several districts for Germany and Menallen townships, while other municipalities maintain their own district systems⁶. In the county ordinance's Rural Residential example, the minimum lot is one acre with 150 feet of width⁶. The cited Rural Residential height starts at 35 feet and can increase with extra lot width, but cannot exceed 50 feet⁶. The county ordinance also limits a property to one accessory dwelling unit, subject to the full accessory-dwelling standards⁶. In the county ordinance's Agricultural District, farms require 25 acres, a single-family detached dwelling requires one acre, and setbacks are 35 feet front, 20 feet side and 20 feet rear⁶. Vacation rentals in Germany and Menallen townships must meet listed conditions, including an on-call local contact and hotel-room rental tax registration⁶. These examples are not countywide; get the parcel's district and dimensional table from its zoning officer before designing a house⁶.

Installing, repairing or replacing a septic system in Adams County requires a permit from the Sewage Enforcement Officer for the parcel's borough or township; routine tank pumping or distribution-pipe flushing does not require that permit⁴. The municipal office can identify the correct Sewage Enforcement Officer². Pennsylvania places most on-lot permitting and enforcement with local agencies rather than a countywide septic office⁴. Hamiltonban Township illustrates how the sequence can work locally: when applicable, its septic permit comes before another construction permit, and its Sewage Enforcement Officer reviews the plans and inspects during and after construction¹¹. Only 14% of Adams County soils are rated without severe limits for a conventional drain field, so arrange the site evaluation before committing to a house location¹².

We could not confirm a countywide rule allowing RV or tiny-home occupancy on private land in Adams County. The parcel's municipality controls the relevant zoning: the county ordinance covers Germany and Menallen townships, the county administers East Berlin Borough's separate ordinance, and all other municipalities administer their own ordinances³. Pennsylvania's state-park campground rules do not answer whether an RV may be used as a residence on private land¹³. In Germany and Menallen townships, an accessory dwelling unit is limited to one per property and must meet the ordinance's complete standards, but that does not establish that every tiny home qualifies⁶. Before buying, ask the municipal zoning officer whether the proposed unit is an allowed dwelling, whether temporary occupancy during construction is allowed, and what sewage approval is required².

1. Identify the parcel's borough or township and zoning district; Adams County publishes the districts it administers in Germany and Menallen townships, while other municipalities administer their own systems⁶.
2. Take the proposed use and site plan to the zoning officer: Adams County handles Germany and Menallen townships and serves East Berlin Borough under contract, while other municipalities handle their own zoning³.
3. Apply through the municipality for the UCC building permit before covered work starts, and arrange the required inspections^1,8.
4. Contact the municipal Sewage Enforcement Officer before installing, repairing or replacing an on-lot system⁴.
5. Ask the municipality whether floodplain approval is needed; participating municipalities require a development permit for regulated floodplain work⁷.
6. Obtain PennDOT approval if the driveway connects to state highway land or a PennDOT drainage facility; Hamiltonban Township separately requires approval for driveways on township-maintained roads^11,14.
7. If the project subdivides land or qualifies as land development, follow the municipality's procedure and applicable ordinance for county review and local approval⁷.

Start with jurisdiction: the parcel's borough or township determines the building-permit route and, except for the county-administered arrangements in Germany Township, Menallen Township and East Berlin Borough, administers zoning directly^2,3. Confirm the district, allowed use, lot size, setbacks and height table before treating acreage as buildable because standards vary by district and municipality⁶. Only 14% of Adams County soils are rated without severe limits for a conventional drain field, making early septic evaluation especially valuable¹². Ask the municipality about mapped floodplain status because floodplain regulation and development permits are local, and New Oxford Borough is the county's exception to NFIP participation⁷. Confirm road jurisdiction before designing access; state-highway connections need PennDOT approval, while local-road rules vary¹⁴. For carrying-cost context, the effective property-tax rate is about 1.4%, and the median annual property-tax bill is about $3,569¹².
