We recently completed a 2 bedroom, one bath, kitchen and living room in 537 square foot addition. This is for a 1,572 square foot home in South San Francisco. Affectionately called “Grandma’s House”, this accessory dwelling is for the mother of the owners.
Below you can see the floor plans, site plans, and the budget for the entire project.
This budget is right before the final invoice. The “Budget” amount is the total cost of all design, engineering, and construction. You can see that the soft costs were approximately $35,000 before the project broke ground. The soft costs are mostly architecture time that we bill hourly.
