| Single-Section Modular Home |
Approximately 600–1,200 sq. ft. |
1–3 bedrooms; usually one level with a compact kitchen and living area. |
- Generally easier to deliver to narrow or constrained sites.
- Requires a route review for width, turning radius, overhead lines, and bridge limits.
- May need fewer on-site module connections than larger designs.
|
Permanent foundation or engineered pier, crawl-space, slab, or basement system, subject to local requirements. |
Confirm locations for electrical service, water or well connection, septic connection, stormwater drainage, and heating or cooling equipment. |
Verify whether the local code classifies the unit as a modular dwelling, manufactured home, or another residential structure. Check minimum floor area, setbacks, lot coverage, and short-term-rental rules. |
Small guest retreat, couple’s cabin, or lower-cost vacation rental. |
| Multi-Section Ranch Home |
Approximately 1,200–2,400 sq. ft. |
2–4 bedrooms; single-story plan with larger shared living spaces and multiple bathrooms. |
- Needs a wider access route and a staging area for multiple modules.
- Confirm crane or set equipment access before finalizing the site plan.
- Suitable for relatively level lots with adequate maneuvering space.
|
Common options include crawl spaces, basements, slabs, and frost-protected foundations, depending on soil, climate, and local code. |
Higher peak demand may require larger electrical service. Plan for water pressure, septic capacity, hot-water demand, and drainage from several bathrooms. |
Review lot width, building separation, fire access, parking count, bedroom limits, and occupancy rules that may apply to vacation rentals. |
Family vacation home, group rental, or accessible single-level accommodation. |
| Two-Story Modular Home |
Approximately 1,600–3,200 sq. ft. |
3–5 bedrooms; bedrooms often occupy the upper floor while living areas remain on the main level. |
- May reduce the building footprint on a small lot.
- Requires careful assessment of road grades, delivery clearances, crane reach, and utility-line conflicts.
- Foundation and structural design must account for local wind, snow, seismic, and soil conditions.
|
Typically requires an engineered permanent foundation designed for two-story loads and local frost depth or seismic conditions. |
Plan vertical plumbing runs, adequate electrical capacity, heating and cooling distribution, and reliable internet service for guest use. |
Check maximum building height, height measurement method, view or ridge-line restrictions, stair and egress rules, parking, and emergency access. |
High-occupancy rental on a smaller site where preserving outdoor area is important. |
| Cabin-Style Modular Home |
Approximately 700–1,800 sq. ft. |
1–3 bedrooms; open living area, covered porch, loft, or large windows are common planning features. |
- Often selected for wooded, mountain, or waterfront settings.
- Site access may be limited by steep grades, trees, narrow roads, or seasonal conditions.
- Minimize disturbance by confirming delivery and crane paths before clearing vegetation.
|
Foundation selection should reflect slope stability, drainage, frost depth, flood risk, and soil-bearing capacity. |
Remote sites may require a private well, septic system, propane or electric heating, backup power, and freeze-protection measures. |
Review tree-clearing limits, slope ordinances, shoreline buffers, wildfire requirements, floodplain rules, and restrictions on seasonal or short-term occupancy. |
Nature-oriented retreat, lake property, mountain rental, or seasonal getaway. |
| Compact Modular Cottage |
Approximately 400–900 sq. ft. |
Studio or 1–2 bedrooms; compact kitchen, combined living area, and one bathroom. |
- Lower material volume can simplify delivery, but small lots may still have difficult access.
- Confirm minimum road width, placement clearance, and service-panel location.
- Outdoor decks, porches, and stairs may require separate permits.
|
Must meet the applicable residential code and local foundation standards; small size does not eliminate structural or anchoring requirements. |
Confirm whether the existing well, septic system, electrical service, and water-heating capacity can support an additional dwelling or guest unit. |
Check minimum dwelling size, accessory-dwelling-unit rules, owner-occupancy requirements, parking, setbacks, and rental licensing. |
Couples’ retreat, backyard guest accommodation, or accessory dwelling on an existing residential property. |
| Accessible Single-Level Modular Home |
Approximately 900–2,000 sq. ft. |
1–3 bedrooms; wider circulation areas, low-threshold entries, and adaptable or accessible bathrooms. |
- Requires a practical route from parking to the main entrance.
- Site grading should limit abrupt changes in elevation.
- Reserve space for accessible ramps, landings, walkways, and vehicle loading.
|
A slab or crawl-space foundation may simplify level entry, but the final design must follow local structural and drainage requirements. |
Place outlets, switches, controls, plumbing fixtures, and mechanical equipment where they can be reached and serviced safely. |
Confirm applicable accessibility provisions, local parking standards, bedroom and bathroom requirements, and any rules for lodging or transient occupancy. |
Multi-generational vacation home, accessible rental, or property serving guests with mobility needs. |
