Looking to build new?

  • Prescriptive (spec) built new home: $400-600 a square foot
  • Custom built new home: $650-1200 a square foot

Keep in mind that these are very rough estimates, and depending on your situation you could spend much more, or perhaps less if you’re crafty!


Contractors, are super busy right now and are booking 6-12+ months out. 


What if you want a killer yard? Jeff’s cheat sheet for landscaping is to take the value of your house:

  1. Irrigation and planting: if you scrape the lot and just do irrigation and planting ~5% of house value
  2. Some hardscape and wood fencing: (but nothing fancy, maybe a fire pit)  ~10%
  3. Outdoor kitchen, extensive paving/deck, arbor, etc  ~15%
  4. Going for it? You can spend 20%+

If you’re only doing part of the site, you can divide by the total area. However, areas that are hard to reach will cost more. For a deeper dive, see their post on the subject
