Reading PA tiny home guide: ADU permits $400–$900, PA UCC building standards, with THOW options in surrounding Berks County.
Last researched May 2026
Reading offers tiny home residents a lower cost of living than most Pennsylvania cities, proximity to the Amish farmland and outlet shopping that define the region, and easy access to rural Berks County for those seeking acreage. Median home prices are among the lowest of any major PA city, which tempers the typical tiny-home savings story somewhat. Climate is humid continental with cold winters (average January low 22°F) and hot, humid summers. Rural Berks County remains the stronger pathway for THOW placement; the city itself is more accessible for foundation-built ADUs.
Reading permits accessory dwelling units in designated residential districts, with fees ranging $400–$900 through the Department of Building and Housing. The city follows the Pennsylvania Uniform Construction Code (2018 IRC), which requires at least one habitable room of 120 square feet and any additional rooms of 70+ square feet. Reading's zoning is less permissive than Philadelphia, Pittsburgh, or Allentown — there is no explicit recognition of tiny home villages, and THOWs are not permitted as permanent residences on standard residential lots. Berks County, which surrounds the city, has more flexibility in rural areas for both foundation-built tiny homes and THOWs placed on private property with the owner's permission. As of April 2026, tiny home pathways in Reading are primarily through the ADU route; THOW owners must rely on RV parks or rural Berks County placements. Affidavits for fire code compliance are required with ADU applications.
Verify current requirements with your local planning department.
ADU permits in Reading run $400–$900 through the Department of Building and Housing. Applications require affidavits confirming fire code compliance and PA UCC (2018 IRC) construction standards. Typical approval timeline is 5–8 weeks. ADUs must be accessory to a primary single-family dwelling and meet setback and utility-connection requirements. The city does not currently offer dedicated tiny home village zoning; multi-unit small-home developments would require rezoning or special-exception relief.
Communities, RV parks, and parking options in and near Reading.
THOWs are not permitted as permanent dwellings on standard residential lots in Reading. Full-time THOW living is limited to licensed RV parks and campgrounds in Berks County and surrounding rural areas. Monthly lot rent at area RV parks typically runs $300–$550, often including water, sewer, and electric. Rural Berks County townships have lighter zoning enforcement — private property placements with owner consent are more feasible outside the city. THOWs must be titled and registered with PennDOT as recreational vehicles under Act 134 of 2018.
