Do you need a building permit in Big Lake, MN?
Big Lake requires a building permit for most projects that build, repair, replace or remodel something; painting, wallpapering and carpeting alone do not require one.1 Big Lake enforces the Minnesota State Building Code inside incorporated city limits.11 City zoning applications are separate from building permits, and electrical permits are issued by the state.1 Do not start construction before the city building permit has been paid for and issued.12 A qualifying owner who personally builds a home may have a state contractor-licensing exemption, but that exemption does not waive building permits or inspections.10
Who is the Big Lake building department, and how do you reach it?
For Big Lake city building permits, contact the Big Lake Building Department through City Hall at 763-263-2107.12 Big Lake contracts with Inspectron Inc. for building inspections; the direct inspection-request line is 651-322-6626.12 Inspection requests need at least 24 hours of notice, and the inspection record card must be posted where it is visible from the street.13 The city publishes a fee schedule, but the applicable cost depends on the project and local fee structure.1415 For a fence, parking pad, pool or shed of 200 square feet or less, use the city’s zoning-application route.12
Does Big Lake have zoning, and what are its lot sizes and setbacks?
Big Lake has city zoning; residential dimensions depend on the zoning district rather than a single citywide acreage rule.5616 In Big Lake’s R-1 Single-Family Residential District, single-family lots need at least 10,000 square feet and 75 feet of width.6 R-1 principal structures have front and rear setbacks of 30 feet and side setbacks of 10 feet; additional road, wetland and overlay standards may apply.7 R-1 maximum impervious surface coverage is 35%, subject to applicable shoreland standards.17 In the AG Agricultural District, single-family lots need at least 5 acres and 500 feet of width, with additional density and subdivision conditions.16 AG single-family principal-structure setbacks are 50 feet front, 30 feet rear and 20 feet side, subject to additional zoning requirements.18
How do septic permits work inside Big Lake?
Sherburne County Planning & Zoning administers septic-system installation and compliance throughout Sherburne County, including land inside Big Lake.3 For a new septic system, start with a state-licensed designer, hire an installer and submit the design and applicable fee to the county Zoning Office for approval.198 The installer must arrange county inspections at least 24 hours ahead; final approval leads to a certificate of installation.19 Holding-tank replacement requires a permit and pumping contract, while listed maintenance such as pump replacement and filter cleaning does not require a septic permit.8 Before planning private sanitation, ask Big Lake Community Development about the parcel’s sewer-connection requirements; we could not confirm a city connection threshold.2
Can you live in an RV or tiny home on land in Big Lake?
Big Lake prohibits using a tent, boat or recreational camping vehicle as living quarters at any time, temporarily or permanently.4 That prohibition rules out using an RV as temporary housing while building a home in Big Lake.4 A tiny house used as a dwelling must comply with Minnesota’s residential code, while local zoning determines placement and residential use.9 We could not confirm Big Lake’s specific tiny-home occupancy, accessory-dwelling or minimum-total-dwelling-size rules; take the proposed structure and parcel details to Big Lake Community Development before buying.2 State tiny-house construction standards alone do not establish local zoning permission.9
Building a home in Big Lake: what are the steps, in order?
- Ask Big Lake Community Development to identify the parcel’s zoning district and review the proposed use against district lot dimensions and setbacks.267
- Resolve wastewater service: ask the city about sewer connection, or obtain county design approval for a proposed septic system.28
- Submit the city building-permit application with the work description, property location, proposed use, construction documents and estimated valuation required by state rules.20
- Pay for the issued building permit before starting work, and arrange required inspections with Inspectron Inc.1213
- Keep work accessible for inspection and obtain the building official’s required certificate of occupancy before using the new home.2122
What stays with Sherburne County, and what should Big Lake buyers check?
Big Lake administers city zoning and building permits, while septic-system installation and compliance remain with Sherburne County Planning & Zoning.213 For land outside city limits, use the Sherburne County guide; the county building-permit jurisdiction excludes incorporated municipalities.23 Sherburne County’s soil rating shows only 0.8% of soils rated not limited for a conventional septic drain field; that countywide figure calls for a site evaluation, not a conclusion that septic is impossible on a Big Lake parcel.24 In regulated Minnesota floodplains, construction and fill require local floodplain approval, and mapped floodways prohibit dwellings.2526 Ask Big Lake Community Development to review floodplain and shoreland constraints before committing to a building site.2
Watch-outs
- Big Lake’s RV living prohibition includes temporary occupancy; do not plan to camp in an RV while building inside city limits.4
- Big Lake R-1 lot and setback standards can be affected by shoreland overlays and other additional standards.67
- We could not confirm Big Lake’s private-well, off-grid sanitation or mandatory sewer-connection rules; ask city Community Development before designing independent utilities.2

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
