What’s behind these numbers?

A curated Seattle demo, calculated by the studio engine: 600 sq ft, cedar finish, shed roof, openings included. Base construction is $340/sq ft, with an 18% soft-cost allowance. Operating expenses use 32.5% of gross rent; estimated annual net operating income is $16,605 before financing and income tax. Simple payback uses the central project estimate divided by this operating income. These are demo assumptions, not verified local quotes or rental comparables. Artwork illustrates the idea, not this parcel or design.

05A LITTLE MORE CLARITY

Good questions.
Straight answers.

A little more help
What is a backyard home?

An accessory dwelling unit, or ADU, is a smaller home on the same property as a primary residence. It can offer independent living space for family or potential rental income, subject to local requirements.

Can I check my address?

Sign in to search a real property. Available parcel and market detail varies by location; the studio identifies assumptions and missing information. You can also explore Seattle, Portland, and Austin demo lots without signing in.

How are the estimates calculated?

The studio combines the proposed size and finish with construction assumptions, rent inputs, and operating expenses. Live-address results show their market basis when available. Demo figures use curated assumptions, and all results need local confirmation.

Does this mean I can build?

No. LotFoundry helps you explore an early concept. It does not grant a permit or guarantee a buildable design. A local professional and your jurisdiction must confirm property conditions and applicable requirements.

What is free, and what costs extra?

Exploring the studio and its initial estimates is free. The complete Certificate of Feasibility is a one-time $29 purchase. You can review what is included before checkout.
