Mount Washington is a genuinely steep hillside neighbourhood with a wide mix of housing, from small 1920s cottages to architect-designed contemporary houses, much of it on parcels with significant grade.
What that means for building here
- Nearly everything here is a hillside project: Baseline Hillside Ordinance limits, geotechnical reports, deep foundations and drainage design.
- Street access is the practical constraint. Narrow winding roads add real cost to deliveries, concrete and staging.
- Retaining walls are ubiquitous and frequently need repair before any other work proceeds.
- A detached ADU here is an expensive proposition, and a conversion or junior ADU is often the better answer.

How we run the job
1. Walk the property
We meet you on site, listen, and look at what the building and the city will need. You get a written scope and a budget range.
2. Drawings
When drawings are needed we bring in the architect and engineer, and price the design while it is being drawn.
3. Permit
We file with the city, handle the corrections they send back, and tell you where it stands.
4. Price and contract
An itemized price, a schedule and payment terms. Anything new after signing gets priced in writing first.

One supervisor on your job, licensed trades, inspections in order, and a weekly update with photos.
6. Walkthrough
A final fix list, the city's sign-off, and a written warranty on our work.
