If you don’t mind my asking, how much did the entire addition cost — fees and permits, design/architectural work, engineering, materials, labor, etc? Also, what are the specifics: attached/detached, size?
We would be interested in doing the same thing when (if??) we buy.

Our case was about as atypical as possible.
We built a detached companion unit – 700sf. Handicap accessible. A very nice looking “casita”.
Architecture – free. My husband is a registered architect.
It was on a slope, so we had civil engineering – 11k for the civil plan
4k for structural (2k building related, 2k for retaining walls)
10k for geotechnical (aka dirt).
If we had a level lot – you could eliminate the geotechnical, civil, and 2k of the structural… Engineering would have been 2k instead of 25k.
Permits – again atypical because we had the hill issues and had to get a civil permit and a separate permit for the retaining walls that hold the building site in place. The building permit was probably $30k, the others were a lot less. Oh and because of the retaining wall footings, we triggered a CalOSHA permit requirement. (Not at all typical.)
Our construction costs are not easily transferable, either… There was grading, building of retaining walls, etc. Oh… and the small issue that our first contractor ripped us off then abandoned the job – adding well over $100k to our total. If we had had a level lot with an honest contractor… It would have probably cost about $140-160k. You don’t want to know what it cost. It was far more due to our specific lot and the worlds worst contractor.
Judging by your screen name, I presume you’re renting. If you plan to do this, make sure the home you buy has a big enough lot. In San Diego (city) you need to have double the nominal size for your zone… In our case we needed at least a 10k sf lot since the nominal was 5k. Our lot was big – but on a canyon – so we had the added expense of grading/retaining walls. Unincorporated county has completely different rules. You’ll want to check what the requirements are for a companion unit for whatever city you buy in. San Diego probably has the most restrictive.
But – it’s worked out well (except financially)… my mother in law finds it much easier to care for my wheelchair bound father in law in a house that was designed handicapped accessible from the start. And my kids get to spend quality time with their grandparents – which is HUGE.[/quote]
Ouch! That was a lot of money, and I remember you mentioning the contractor — even though you tried to do a thorough background check, IIRC. Not uncommon, unfortunately. We’ve heard many similar stories, and this is probably my biggest fear in building or adding on.
I thought your DH did commercial work…would he be interested in doing residential, and if so, how much would he charge for a 2,500-3,000 s.f single-story house?
Your last paragraph is what makes it all worthwhile, though. This is exactly what we want to do. If we build our home from scratch, I want to incorporate “universal design” elements just for this purpose, and for ourselves in our old age. The companion unit is a given as far as handicap accessibility. Even if your in-laws aren’t using it, there is a shortage of wheelchair-friendly rental housing, IMHO.
Not sure why so many houses were built during the boom with absolutely no regard for ADA compliance. My biggest gripe is with the two-story houses without a full (wheelchair-friendly) bathroom and bedroom on the bottom floor. As if nobody ever gets injured or disabled???
