What are possible environmental concerns that delay home construction/additions and why do they do so?
Social: 1) Neighborhood, 2) schools: Many clients come to us to “remodel” their existing house because they like the neighborhood. They could find better land values elsewhere and probably build new cheaper, but they like their neighbor’s, etc. 

Economic: 1) Financial, 2) investment: You probably won’t own that investment forever. Review trends in your area for increasing value. Will you need financing? Lending institutions require adequate time for closing. 

Regulatory: 1) Adequate review period for permits, 2) adequate time for sub bids, utility install, etc. 

Environmental: 1) Weather acceptable for material installation: Where I live, we build year-around, but it costs more in the winter because it’s slower and we have to protect our work from the weather. 

Design: 1) adequate time for design review considerations, changes, etc. 2) adequate time to obtain materials and equipment. If you’re adding a second floor bath, do you have adequate water pressure? Will you a new electrical service added by utility? If you are not hooked up to the local sewer utility, you’ll need adequate time for soil sample analysis, testing and design approval. Likewise for water and you’ll need adequate distance between water supply (well) and septic system (septic tank and drainfield.
