Oak Park

Which era's questions apply here

For a house of 1950, the questions are the post-war ones: 60-amp original service, galvanized steel supply piping, cast-iron and clay drains, and the pre-1978 lead-based paint disclosure requirement.

If houses run into the 1960s and 1970s, aluminum branch circuit wiring becomes a live question for a substantial part of the neighborhood — it was used from roughly the mid-1960s to the mid-1970s, and the concern is the connections rather than the wire, with a specific and well-established remedy at every device rather than wholesale rewiring.

And if any houses reach the late 1970s, polybutylene supply piping enters the picture instead, which is a different question again with a different answer.

A twenty-year range means alteration as well as variety

At seventy years or more, alteration explains much of the size and bathroom range.

Houses of this era and size are among the most commonly extended and reconfigured in any market. Bedrooms get added into a lower level, over a garage or in a rear extension. Bathrooms get added, which at this vintage is the single most common improvement of all — a one-bathroom original becoming a two- or three-bathroom house is an ordinary history here.

That means bedroom and bathroom count do more work in setting a price than square footage does, and comparables must be matched on both rather than averaged. A one-bathroom original and a three-bathroom altered house on the same street are not the same product, and the difference is proportionally large in a house of this size because there is less of everything else to compensate.

It also makes the permit record unusually valuable. The city's building department holds it, checking costs nothing, and it tells you whether an addition was inspected, whether an added sleeping room has proper egress, whether plumbing was vented correctly, and whether a converted space was ever brought up to standard.

For a seller of an altered house, having the permits to hand converts the largest question about the property into a documented answer. For a seller of an unaltered one, original condition is itself worth stating.

Michigan states bathroom counts with full bathrooms before the decimal and half bathrooms after: two-point-one means two full and one half. Count fixtures at a showing rather than trusting the notation.

Ranches and two-story houses

A neighborhood holding both is holding two products, and matching on form comes before matching on area.

The ranch reaches the widest and most persistent buyer pool, because single-level living is a requirement rather than a preference for a substantial and growing number of buyers — and there are always more of those buyers than there are single-level houses. That is why ranches routinely outperform what their measured area suggests, and why the gap tends to widen rather than narrow over time.

A ranch also has more roof per square foot of living space than a two-story house, which makes the roof a proportionally larger replacement expense — relevant at seventy years, when the roof has been done several times and the question is when and with what.

And a ranch usually has a full basement beneath, which is where the wiring, plumbing and any period materials are visible, making it the most informative room for an inspection and the one worth spending time in.

Where a basement has been finished, below-grade space is generally not credited by appraisers in the same way as above-grade square footage — so a house with a finished basement offers more usable space than its stated area implies while appraising closer to that stated area. That is an opportunity for a buyer and a reason for a seller to describe the space carefully rather than simply adding it to a total.

A finished basement in a house of this age also conceals what an inspector would otherwise see, which makes the seller's written answer about water history more valuable, not less.

The east side, and a park next door

Oak Park is a city holding, and publicly held parkland is the most durable tier of protected open space: not a business that can close and be sold, and not dependent on anyone continuing to fund it out of an assessment. It is the only category that does not need somebody to keep paying for it.

That is a permanent feature of the location, and it is exactly the kind of advantage a square-footage comparison ignores — an automated valuation reads a city park and an unbuilt private field identically.

A public park is used, and the balance between outlook and activity depends on what it contains and where a house sits relative to it. A quiet green is a different neighbor from a lit court or a playing field, and the difference is felt most on summer weekends. Standing on the lot on a Saturday afternoon in season tells you more than any description.

The east side of the city sits in the Malletts Creek drainage in part, and that watershed is worth knowing about: Malletts is the main outlet for stormwater runoff from the city, much of it in underground piping, with close to thirty-seven percent of the land draining to it impervious — which is why it responds sharply to heavy rain. The Washtenaw County Water Resources Commissioner is the authority, flood plain status is parcel-specific.

Mature canopy on a street of this age is both an asset and an owner's obligation: an arborist's opinion on anything large near the house, four-figure removal costs, recurring pruning, and leaf drop into the gutters and valleys where roofs fail first. And on a street of this age, a camera inspection of the clay or cast-iron drain lateral is among the better-value additional checks available.

Pittsfield Township, with an Ann Arbor address

Oak Park pays Pittsfield Township taxes and takes its mail at an Ann Arbor address. Pittsfield is a separate government from the City of Ann Arbor, with its own board, tax rate, services, zoning and assessor, and the rate difference between a township parcel and a city one is real and recurring. Comparable sales are matched on municipality first.

Ann Arbor Public Schools serves the subdivision. For a seller, naming Pittsfield Township, the Ann Arbor address and Ann Arbor schools together widens the pool: buyers searching on any of the three will find the property, and none will be surprised by the tax bill.

Four tiers of protected open space

Where open ground adjoins a property, ownership is the first thing that decides whether it stays open — but not the only one.

Land held by a public body is generally the most durable, though a public body can still sell or repurpose land. Land under a recorded conservation easement is next — an easement runs with the land, surviving a change of owner and of local board. Association common area is real protection that the owners themselves pay for. Unbuilt private land carries the least protection of the four, but that is not the same as none: zoning, recorded deed restrictions and state wetland regulation can each constrain what may be built, filled or cleared, and EGLE requires authorization for specified activities affecting regulated wetland.

From a window all four look identical, which is why it is worth checking the record rather than the view: ownership, any recorded easement or restriction, the zoning, whether wetland is mapped, and whether a development application has already been approved.

Schools

Oak Park is served by Ann Arbor Public Schools. District boundaries are redrawn from time to time.

Buying or selling here

The year built and the permit record are the two things that decide a transaction here, and both are free.

For a seller, the assessor's year built settles which era a house belongs to, and the permit record for every addition and added bathroom converts the largest question about an altered house into a documented answer. Very few sellers obtain either.
