Questions people ask

Can I get one of these exactly?

Each was designed to its lot and city. Yours starts from the same standard and the size your lot allows.

Are these "pre-approved"?

Depends on the city. Some run pre-approved plan programs; elsewhere the design goes in with your permit.

What about an addition or a conversion?

Those are designed to your house, not picked from a catalog. The report covers them the same way.

Which one fits your lot?

Two minutes to ask. A few hours to know.
