Home Building questions, answered by experts

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

Most cottages are around 1,000 square feet, making them smaller than most other styles. However, cottages are defined more by their decor and architectural focus on simplicity, functionality, and a connection to nature than they are by a rigid square footage or floor plan. While cottages are defined more by their charm and appearance than size, the smaller footprint does help maximize the comfort and charm, and it keeps the focus on connection to nature and family.

A construction lien results from unpaid services. For instance, if a homeowner hires a contractor to do a large renovation on their home and then fails to pay for the services and materials, the contractor can take out a lien on the property. This lien is a legal claim against the property for the amount of money owed. If the homeowner does not pay their debt, the lien may stay on the title until the homeowner tries to sell and cannot do so until the title is cleared.

Yes, a garage apartment is generally considered a valuable asset as long as the new structure has been legally built. It's important to weigh the cost to build a garage with an apartment against the cost to convert a garage to living space if you already have a garage.
