Do you need a building permit in Rochester Hills, Michigan?

Rochester Hills requires a building permit before construction of a building or structure, and a permit is also required when a structure’s use or occupancy changes.1 Ordinary repairs are exempt, but structural, egress, plumbing, electrical, mechanical and other work affecting health or safety falls outside that exception.1 Michigan’s own-use owner-builder exemption concerns residential-builder licensing: an owner building for personal use and occupancy on the owner’s property still must meet applicable building-permit, inspection and zoning requirements.7

Who handles Rochester Hills building permit applications and inspections?

Contact the Rochester Hills Building Department at 248-656-4615 for building permit application questions.8 Rochester Hills allows required documents and fees to be submitted online, and building-permit inspections must be scheduled through BS&A Online using the application login.8 Ask the Building Department for the application requirements and fee schedule for your proposed work before submitting plans.8 For zoning questions, contact Rochester Hills Planning & Economic Development at 248-656-4660; septic permits remain with Oakland County Environmental Health Services.93

Does Rochester Hills have zoning, lot-size rules and setbacks?

Rochester Hills has city zoning districts, so confirm the parcel’s district with Planning & Economic Development before choosing a building layout.29 In the R-5 One-Family Flex Residential District, the single-family building type requires at least 6,000 square feet per dwelling unit and a minimum lot width of 50 feet.6 R-5 requires a front and street-facing side yard of at least 15 feet, an interior side yard of at least 5 feet with 15 feet total, and a rear yard of at least 35 feet.10 R-5 building lot coverage is capped at 50 percent; these R-5 dimensions should not be applied to parcels in other districts.1112

How do septic permits work inside Rochester Hills?

Oakland County Environmental Health Services issues septic permits and conducts construction and final inspections for onsite systems serving Rochester Hills property where municipal sewer is unavailable.3 A new residential onsite system needs a new-system permit; replacement, alteration or repair of an existing residential system needs a repair permit under the stated existing-structure and sewage-flow conditions.5 Oakland County lists a new residential septic permit for vacant land at $325 and a repair permit at $221.13 Follow the inspection requirements written on the septic permit; if no special inspections are listed, the final inspection must occur before covering the system.14

Can you live in an RV or tiny home in Rochester Hills?

Rochester Hills prohibits using recreational vehicles and similar units for living or housekeeping on residential premises; the parking rule also requires an occupied dwelling on the lot.4 Utility connections are prohibited except temporary electricity for battery recharging.4 A Building Department temporary permit can allow RV parking on private property for up to 2 weeks, but that parking provision does not authorize residential occupancy.4 We could not confirm a distinct tiny-home or accessory-dwelling rule; ask Rochester Hills Planning & Economic Development about the proposed dwelling and parcel before buying.9

Building a home in Rochester Hills: what should you do first?

  1. Ask Rochester Hills Planning & Economic Development to confirm the parcel’s zoning district and the dimensions applicable to your proposed home.29
  2. Establish whether municipal sewer is available; where onsite sewage disposal is needed, arrange the septic application with Oakland County Environmental Health Services.35
  3. Submit the building permit application and required documents to Rochester Hills before construction.18
  4. Schedule building inspections through BS&A Online and arrange the septic inspection before covering the system.814

What should you check before buying land in Rochester Hills?

Ask Oakland County Health Division about the private-well requirements for the proposed parcel: Michigan counties require a local-health-department well permit or notification before drilling, and the applicable local conditions differ.15 We could not confirm Rochester Hills’ general new-home utility-connection rule or a complete rule for off-grid sanitation; ask the city Building Department and Oakland County Environmental Health Services about the proposed setup.814 State floodplain rules prohibit new residential construction in the floodway.16 For property outside Rochester Hills, consult the Oakland County guide; Oakland County’s absence of county zoning does not establish an absence of municipal or township zoning.17

Watch-outs

  • Temporary RV parking permission in Rochester Hills does not allow living or housekeeping in the RV.4
  • We could not confirm when Rochester Hills requires a certificate of occupancy; ask the Building Department before planning a move-in date.8
  • Manufactured homes in Rochester Hills manufactured-housing communities must be connected to water, sanitary sewer, electricity and other necessary facilities before dwelling occupancy.18
