Does Doylestown Township have zoning, and can you live in an RV or tiny home?

Doylestown Township has its own zoning ordinance and a Zoning Hearing Board that handles special exceptions and variances.³ We could not confirm general RV occupancy, tiny-home occupancy, minimum dwelling size, or district-specific lot size and setbacks; ask Township Code and Zoning to review the intended use and parcel before buying.⁸

The verified R-1 accessory-family-apartment route requires a special exception and limits occupancy to family members or a family caregiver.⁶ That route limits the apartment to 25% of the principal residence’s usable floor area and excludes manufactured homes, RVs and wheeled structures; it does not establish a general tiny-home entitlement.⁶

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

Doylestown Township residential construction covered by Pennsylvania’s Uniform Construction Code requires a building permit before work begins, subject to the code’s listed exceptions.¹ The township’s new-home checklist calls for building, mechanical, plumbing, electrical and applicable sprinkler applications to be submitted together.²

Start with Doylestown Township Code and Zoning for building-code and zoning questions; the township makes reference copies of its construction codes available at the administration building.⁸ The township identifies the 2021 ICC codes as its current construction-code references, with separate accessibility provisions for nonresidential buildings.⁹ Ask the office which current fee schedule and project-specific applications apply before preparing a submission.⁸

How do septic permits work inside Doylestown Township?

Bucks County Department of Health requires a septic permit for covered installation, construction, alteration, repair, connection or occupancy involving an individual or community sewage system.⁴ The township’s new-home checklist requires a copy of the county septic permit or a sewer connection agreement from BCW&SA.² County sewage approval therefore belongs in the building-application plan, rather than being left until construction finishes.²

Before occupancy of a structure served by a permitted on-lot system, the county requires written Approval to Cover and a final inspection by its Sewage Enforcement Officer.¹⁰ County rules also prohibit use of an on-lot system where an approved public sewer is accessible; ask Health to resolve sewer availability before designing a septic system.¹¹

Building a home in Doylestown Township: what are the steps?

Begin with the township’s new-home application checklist and resolve sewage, water and access documentation alongside the building plans.²

1. Ask Code and Zoning to confirm the proposed use and identify any special-exception or variance review.³⁸
2. Obtain the county septic and well documentation, or the relevant sewer and water connection agreements listed by the township.²
3. Prepare the driveway highway-occupancy application or PennDOT permit copy, site plans, architectural plans and construction applications required by the checklist.²
4. Keep permitted residential construction accessible and notify the construction code official when work is ready for inspection.¹²
5. Complete final inspection and obtain the residential certificate of occupancy before moving in; the township checklist also requires a signed stormwater maintenance agreement before issuance.⁷²

What stays with Bucks County, and what should you check before buying in Doylestown Township?

Bucks County Health retains the septic-permit role and regulates wells outside Pennsylvania DEP’s well program, including construction, alteration and abandonment standards.⁴⁵ The township checklist requires a well permit and water test when a new home uses a well, or a water connection agreement from Doylestown Township Municipal Authority.²

County sewage rules require kitchen and laundry wastewater and water-softener backwash to enter a treatment tank; an off-grid plan still needs an approved wastewater approach.¹¹ We could not confirm the parcel-specific floodplain, grading or driveway requirements; ask Township Code and Zoning to identify the applicable reviews before closing.⁸ For land outside the township, consult the Bucks County guide and identify the municipality responsible for local zoning.¹³

Watch-outs

• An R-1 accessory family apartment is a conditional family-or-caregiver use, not blanket permission to rent a separate dwelling.⁶
• We could not confirm permission to occupy an RV while building in Doylestown Township; ask Township Code and Zoning before planning temporary housing.⁸
• A residential building in Doylestown Township needs a certificate of occupancy before use.⁷
