Types of Home Additions Popular in Ogden

Homes in Ogden range from older bungalows and brick homes to 1970s split levels to new suburban developments. The most common additions Salt to Summit builds in Weber County include:

1. Primary Suite Additions

A popular upgrade for older Ogden homes lacking large bedrooms or ensuite bathrooms.

These additions typically include:

• Large bedroom space

• Walk-in closet

• Custom bathroom with tile shower

• Optional vaulted ceilings

  
  

2. Living Room or Great Room Extensions

Useful for homes with smaller original layouts. Often involves removing a rear wall and extending outward.

3. Kitchen Expansions

One of the most requested addition types. Helps transform older galley kitchens into open, modern spaces.

4. Attached Garage Additions

Older Ogden neighborhoods often lack garage space. Attached garages add value and storage.

5. Second-Story Additions

Ideal for neighborhoods where yard space is limited. These are more complex and typically require significant structural upgrades.

6. Sunrooms and Four-Season Rooms

Great for maximizing natural light and adding flexible square footage without a full structural addition.

7. Basement or Lower-Level Additions (Walk-Outs)

In South Ogden and Pleasant View, some homes with slopes can create walk-out additions under existing structures.

What Affects the Cost of a Home Addition in Ogden?

Several factors determine total cost.

1. Foundation and Footings

Every addition needs new footings and foundation work. Soil conditions on the east bench or areas with slope may require additional engineering.

2. Structural Tie-In

Connecting the new addition to the existing home can involve:

• Removing exterior walls

• Adding beams

• Reinforcing load paths

  
  

Homes built before modern building codes often require structural upgrades.

3. Utilities

Plumbing, HVAC, and electrical must extend into the new area. Bathrooms and kitchens increase costs more than bedrooms or offices.

4. Roofing Modifications

Blending the new roofline into the existing structure can add engineering and labor cost.

5. Interior Finishes

Flooring, trim, cabinetry, tile, and fixtures vary widely in price depending on style and quality.

6. Window and Door Upgrades

Additions typically require new windows, exterior doors, headers, and energy-efficient options.

7. Size and Complexity

Bigger additions cost more, but complex shapes and second-story builds dramatically increase cost per square foot.

Zoning and Permitting Rules in Ogden

The permitting process is one of the most important steps in planning an addition.

Ogden requires permits for:

• Any structural addition

• Adding or moving plumbing

• Adding new electrical circuits

• Foundation or footing work

• Roof extensions

  
  

Zoning considerations may include:

• Setback requirements

• Lot coverage limits

• Height restrictions

• Proximity to neighbors

  
  

Neighborhoods like East Bench, Downtown Ogden, or older historic districts may have additional rules or architectural guidelines.

Salt to Summit helps homeowners navigate drawings, engineering, and the city application process.

Home Addition Timelines in Ogden

Typical addition timeline:

10–20+ weeks, depending on scope

General schedule:

• Engineering and design: 2–4 weeks

• Permitting: 2–6 weeks depending on complexity

• Foundation and framing: 3–6 weeks

• Mechanical trades (electrical, plumbing, HVAC): 2–4 weeks

• Insulation and drywall: 1–2 weeks

• Flooring, trim, and finishes: 2–4 weeks

Weather can impact timelines, especially during winter months.

Design Tips for a Successful Home Addition in Ogden

1. Match the Architecture

Additions look best when they blend seamlessly with the original home’s design.

2. Align Rooflines and Eaves

Matching pitch and soffits makes the addition look intentional and cohesive.

3. Consider Natural Lighting

Strategic window placement improves livability and reduces the need for artificial light.

4. Plan for Future Use

Think about resale, aging-in-place needs, multigenerational living, or rental scenarios.

5. Keep Traffic Flow Simple

Avoid layouts that create bottlenecks or dead-end spaces.

6. Avoid Overbuilding for the Neighborhood

Salt Lake or Park City-level finishes may not yield the same ROI in every part of Ogden.

Are Home Additions Worth the Investment in Ogden?

In most cases, yes.

Benefits include:

• Increased square footage

• Higher resale value

• Better layout for growing families

• Potential for added bedroom count

• Modernized home design

  
  

Ogden homes in neighborhoods such as North Ogden, South Ogden, Pleasant View, and East Bench typically see strong returns for well-designed additions.
