Zoning, building permits and septic rules in Monessen, Pennsylvania

The City of Monessen, Pennsylvania, in Westmoreland County, administers its own Uniform Construction Code, so building permits come from the city12. Monessen also has its own zoning ordinance, with variances handled by the Zoning Hearing Board3. We could not confirm who issues septic permits inside city limits; ask City Hall at 724-684-90004.

Does Monessen have zoning, and what does it mean for RVs, tiny homes and setbacks?

Yes. Monessen adopted its own zoning ordinance, and uses and structures inside city limits must comply with it3. Variances and special exceptions go through the Zoning Hearing Board3.

Westmoreland County does not zone, so the county has no say over land inside Monessen11. The ordinance's district rules decide what you can build and where.

We could not confirm what the ordinance says about RV occupancy, tiny homes, accessory dwellings, minimum house size or lot coverage. Do not assume any of them is allowed. Ask City Hall for the zoning district of the exact parcel and the use table for that district4.

Do you need a building permit in Monessen, and who issues it?

Yes. The City of Monessen adopted the Pennsylvania Uniform Construction Code as its building code1 and elected to administer and enforce it itself2. Building permits for construction inside city limits therefore come from the city, not from Westmoreland County, which does not issue building permits12.

The city posts an application for UCC building permits on its permits page13. Fees are set by city resolution, and the state adds $2 to every construction permit issued under the UCC10.

Emergency repairs or equipment replacements may start before a permit if an application reaches the building code official within three business days2. Covered work is inspected, and a certificate of occupancy must be issued before a building can be used56.

How do septic permits work inside Monessen?

We could not confirm who issues on-lot septic permits inside Monessen city limits. City Hall is the place to ask first4.

One rule is clear: where a property abuts a public sanitary or combined sewer, the city code makes it unlawful to dispose of sewage any other way than into that sewer8. A lot on a sewer line is not a septic lot.

Pennsylvania requires a permit for any building served by an onlot sewage system, and local agencies and Sewage Enforcement Officers handle that permitting under state oversight1415. Pennsylvania also does not require a license for homeowners who drill their own water wells, though we could not confirm any Monessen well rule16.

Building a home in Monessen: the steps, in order

  1. Call City Hall at 724-684-9000 and give the parcel address to confirm its zoning district and whether public sewer abuts it43.
  2. Check the use and dimensional rules for that district; variances go to the Zoning Hearing Board3.
  3. If you are dividing a lot, review the city's subdivision and land development chapter first7.
  4. Submit the UCC building permit application and pay the fee set by city resolution1310.
  5. Schedule the inspections the UCC requires as work proceeds5.
  6. Obtain a certificate of occupancy before anyone uses the building6.

What stays with Westmoreland County, and what to check before you buy in Monessen

Westmoreland County has no zoning ordinance and no building permit office, so neither decision sits with the county for Monessen addresses1112. The county's subdivision ordinance applies only in municipalities without their own, and Monessen has its own subdivision chapter177. For land outside the city, see the Westmoreland County page.

Driveways onto a PennDOT road need a state highway occupancy permit18. Check whether the parcel lies in a Special Flood Hazard Area, because development there needs a floodplain permit19.

Westmoreland County's effective property tax rate is about 1.3%20.

Watch-outs

  • We could not confirm the owner-builder rules inside Monessen city limits; ask City Hall before acting as your own contractor4.
  • We could not confirm short-term rental, driveway or accessory-dwelling rules inside Monessen; ask City Hall before you buy for those uses4.
  • Monessen's city code lists floodplain provisions, so confirm flood status for any parcel before you commit19.

Unanswered questions are usually a sign that Monessen publishes no rule on the point, not that none exists. Westmoreland County’s page lists the county offices to call.
